Touch Screen guide
There are so many LCD monitors on the market, it can be difficult to
know where to start to find the right ones for your application. From
desktop monitors, medical monitors, colour accurate displays to large
format displays for public areas and video walls to touch screens.
The terminology doesn’t always help, as people refer to LCD monitors as
LCD displays, LFD’s (large format displays) and LED monitors. The latter
are LCD monitors with LED back lights which means these monitors
have lower power consumption, therefore are energy efficient with
slimmer design.
The aim of this guide is to give you an overview of LCD monitors and
touch screens, keeping technology simple with solution ideas and
hopefully help you make the right choice for your requirements.
Wedgwood AV Ltd., supply a wide range of LCD monitors and touch
screens for education, healthcare and businesses: projectors, interactive
whiteboards, lecterns, visualisers, digital signage and other audio
visual and IT equipment, across the UK. For product comparisons,
manufacturers’ brochures and sales support please visit our website or call 01754 769967. Contact form.

NEC video wall
LCD monitors range in size from around 15” upwards
for desktop monitors and from 32” upwards for public displays
This LCD monitor and touch
screen guide is intended to give an
overview of the different types of
LCD monitors on the market, from
desktop models to large format
displays designed for video walls
and digital signage advertising in
public areas.
Specialist medical monitors are
available for healthcare for diagnostic,
review and reporting of medical
images. For example, X-Rays, CAT
scans and MRI images can be viewed
on desktop medical monitors, perhaps
with students observing on large
format portrait (vertical) displays for
medical training.
We look at the differences between
buying a consumer TV intended for
4-5 hours viewing a day, compared
to professional displays some of
which are designed to be used
24/7 for a range of applications.
Other specialist desktop LCD monitors
include colour correction models for
CAD, photographic, publishing and
other colour critical applications.
Desktop computer monitors are
available in 4:3 video format and
16:9 or 16:10 widescreen formats. A
wide range of mounting options are
available on the market, including
multiple screen desktop stands so
you can mount dual monitors, triple
monitors, quad monitors, 6 or 8
monitors, ideal for financial and
control room applications.
Large format displays start from 32”
upwards and are used for a variety of
applications across several industries.
You can buy IP (Ingress Protection)
rated outdoor screens or TVs for hotel
gardens, pub patios and spa and pool
areas; dust and grease proof monitors
for fast food restaurants and factories;
and high brightness ‘sunlight readable’
models, for displaying information in
shop and office windows, especially
for digital signage applications.
LCD monitors are sometimes referred
to as TFT LCD monitors. A Thin Film
Transistor (TFT) is a variant of Liquid
Crystal Display (LCD) and is widely
used for TVs, computer monitors,
projectors and mobile phones.
In-Plane Switching (IPS) panels
give wide viewing angles and good
colour and can be found in high-end
ViewSonic LED desktop monitor
More common these days are LED
monitors, also referred to as LED TV’s
or LED panels. These monitors are
LCD monitors with LED (light emitting
diode) back lights. LED display

screens are much thinner in design
than traditional LCD monitors, use
less power consumption, therefore
saving energy, and the LED’s can be
controlled, for example, dimming the
light in bright environments.
We are also seeing curved display
screens on the market, especially
curved LED TVs for the consumer
market. Coupled with high contrast,
LED TVs and LED monitors display
images with deeper blacks and richer
Large format display screens for
public areas can often be used
(depending on make and model) in
either landscape (horizontal) or portrait
(vertical) mode. Large screens in
portrait mode are particularly useful
when reviewing medical images for
medical training, or for life size images
in museums and galleries or in retail for
displaying fashion show videos.
Large widescreen LCD monitors are
impressive for exhibition stands and
reception areas. Four, nine, twelve
or sixteen 32” to 80” (diagonal inch)
screens wall mounted to form a video
wall are ideal for shopping malls,
sporting events and concerts.
The size of the bezel (the screen’s
surround) is important when using
display screens in video walls. Some
screens have an almost seamless
bezel, but these tend to be more
expensive than standard size bezels.
Some manufacturers large format
displays have Open Pluggable
Specification (OPS) slots to
accommodate a slot-in PC, ideal for
displaying digital signage presentations
at varying times of the day in bars,
restaurants, schools and retail stores.
LCD TVs are designed for home users
and generally have a manufacturer
1 year RTB (return to base) warranty.
They are designed for watching TV
4-5 hours a day. Commercial LCD
monitors, especially those that are
warranted for 24/7 usage, are of much
better build, have more inputs, and
better manufacturer warranties, such
as 3 year RTB or 3 year swap-out
where the manufacturer swaps your
faulty LCD for a working one of similar
age and usage.
Hotel TVs are available for hospitality
and hotels and these can include
clocks and provision for hotel logo
and menus. Models that allow cloning
save time, for once you’ve chosen
settings such as maximum volume,
then you can save the settings onto
a USB memory stick, which can then
be inserted into all the hotel TVs in
the establishment and the settings
transferred simply and quickly.
Touch screen overlays are available
for LCD monitors. However in recent
years there has been a growth of
touch screen monitors. Single touch,
dual touch, and now multi-touch
which let you use gesturing such as
zoom and pinch, are in use for many
applications. 4-point, 6-point, 10-point
and even 20-point touches or more
are available on the market.
NEC medical monitors
iiyama multi-touch monitors
Large widescreen touch screens with
anti-bacterial coating, so they can be
wiped down, are ideal for medical
applications such as on hospital wards
for bed management. Anti-bacterial
wall brackets and trolleys are available
to complement medical monitors.
When choosing touch screens it is
advisable to seek specialist advise
before purchasing, as there are several
types of touch technology including
infrared (IR), optical sensing (OS) and
AG Neovo LED
projected capacitive (PCAP). Some
surveillance monitors
are best for drag and drop
applications whilst others are
CleverTouch LCD displays
better when using gloved hands
such as in hospitals, science
laboratories and factories.
High resolution surveillance
displays are designed with
control centres, security
command centres and other
security environments in mind.
Typical features may include
hard glass protection, anti-burn
protection, robust for 24/7
usage and technology that reproduces
CCTV images at high resolutions.

Displaying video and LCD televisions
LCD monitors are normally designed for computer use and
so anything that can be run on the computer will appear on
the monitor. If the computer has a DVD drive, then you can
play DVD movies with DVD player software...
LCD monitors normally have a
High-Definition Multimedia Interface
(HDMI) or Digital Visual Interface (DVI)
port on the back to connect a DVD
player, Freeview box or other video
source into them. Prior to these
video ports, you would normally have
connected devices using component
video inputs.
LCD televisions are video compatible
LCD monitors that have a TV tuner
built in. A TV tuner allows television
signals to be received. An external
TV tuner box can be purchased for
use with any video compatible LCD
monitor which will effectively turn it
into a television. You can connect
satellite systems and digital set-top
boxes on any video compatible LCD
monitor to receive digital television
signals, such as Sky. Games
consoles such as the PlayStation 3
or the Microsoft X-Box, can also be
In the UK, we usually look in high street
retailers, such as Argos, when we want
a new television. You can buy 32” LED
TV’s (LCD TVs with LED backlights) for
around £249 including VAT, and a 42”
Full HD Freeview HD 3D Smart TV for
around £399 including VAT. Other sizes
include 40”, 50”, 55” 60”, 65”, 70” and
84” diagonal. Being TVs, they come
with speakers, a desktop stand and
built in digital TV tuner, most come with
Freeview or Freeview HD.
Netflix for watching digital movies,
YouTube for uploading and watching
videos, Skype for instant messages
and communication and Facebook, a
social media website, for keeping in
touch with family and friends. You can
share content from your laptop, tablet
or smartphone with your TV.
Full high definition (Full HD 1920x1080
pixels) Smart LED TVs are slim models
which normally include Freeview
HD, an Internet browser and Apps
(Applications) and a USB connection
which lets you view your digital photos,
music and movies on a large screen
and even play your digital music
from a USB memory stick. You can
also pause live TV. Smart Apps may
include BBC iPlayer, for catching up
on missed BBC TV programmes,
A Smart 3D LED TV, for example, lets
you view television programmes in 3D.
There are two types of 3D, passive or
active. Passive 3D is cinema-like 3D
that you view with inexpensive passive
3D glasses. Active 3D uses battery
operated shutter glasses, which are
more expensive than passive 3D
Smart TVs with an in-built HDD
recorder (digital video recorder) allows
you to pause and rewind live TV.
Combi TVs are televisions with builtin DVD player and are ideal for a
bedroom, study or small room.

Commercial LCD TV models are
designed for use in business premises,
such as bars, hotels and restaurants.
Commercial TVs with hotel mode allow
you to customise display settings such
as setting a maximum volume control,
and then copy the settings onto a
USB Flash memory, which can then be
copied to other hotel mode TVs.
LCD monitors
LCD desktop monitors are commonly
used in education and business
administration, whilst large format
displays (LFD), which are generally 32”
diagonal and upwards, are designed
for commercial applications, especially
in reception areas, museums and
galleries, airports, retail and other
public areas. These usually do not
include a TV tuner. Most do not
include speakers or any sort of stand
in the basic price. When you add
speakers or a soundbar and a stand
or wall mount bracket, you are looking
at paying around 50% more for what
looks like an LCD TV.
The reason for paying around 50%
more for the widescreen LCD monitor,
is the usage. LCD TV’s are for home
use and are designed to be used
4-5 hours per day and usually have a
manufacturer 1 year RTB warranty.
Commercial LCD / LED monitors are
designed to be used 12-24 hours
per day (depending on make and
model) as information displays and
usually come with 2 or more years
manufacturer warranty and have a
far higher build quality and choice of
inputs. For example, a London retail
chain put consumer TVs in their shops
to display video advertisements during
opening hours. After a few months
the TVs began to fail, as they were not
up to the task of being used 10 hours
per day. Large format displays (LFD),
as these LCD screens are commonly
called, which 24/7 warranty are
available, often with landscape and
portrait mounting options.
Another difference is the connectors
(inputs) on the back of the monitor
display screens, there being normally
more connectivity on commercial
models than on consumer ones.
If you want to run digital signage
software on a display screen in a shop
window, then buy an LCD monitor
not an LCD TV. However, if you want
to show TV in reception areas, then
a commercial TV would be a better
option than a consumer TV. AquaLite,
for example, specialise in Ingress
Protection (IP) rated TVs and sunlight
readable TVs for outdoor use. They
manufacture both weather-proof and
waterproof televisions suitable for
indoor and outdoor entertainment,
digital signage and advertising
displays. Samsung include MagicInfo
Lite with their LFDs, which an uses
HTML5 browser to display basic digital
signage presentations on screen, with
an option to upgrade to their Premium
editions of MagicInfo signage software.
Video cameras and visualisers
(document cameras) can also be
connected into an LCD monitor with
a video port. Visualisers are desktop
cameras with a flexible neck, flatbed
or ceiling mounted, the latter being
used in operating theatres for
displaying live images, in higher
education for demonstrations and
in the corporate world for video
conferencing. Visualisers allow you to
display small objects and documents
such as papers and book or magazine
pages, onto an LCD monitor or large
format display screen. Images or video
can also be captured to a computer.
AVer flexible arm visualiser
and contrast
Brightness is measured in candelas
(cd/m2) and LCD monitors normally
range from 250 to 700 cd/m2. The
brightness doesn’t usually matter
if you are using an LCD monitor on
your desk, but if you are using one
as a display board in a reception area
for example, the brighter the better.
High brightness models are available,
sometimes referred to as ‘sunlight
readable’, which have around 1,500
cd/m2, designed for use in retail stores
where ambient light is very bright and
for shop and office windows, especially
south facing where bright sunlight can
be a problem.
The contrast ratio is the difference in
definition between the colours black
and white when displayed on screen.
The higher the number, the better the
definition and the better the colour
black is displayed on screen which
gives a better image especially if you
are playing DVD movies.

You can find out which resolution your computer is using on Windows based
machines by opening the Windows Control Panel and searching for the
adjust screen resolution option.
Do this for all the computers you may be using with your LCD monitor.
On any type of screen, the more pixels
there are, the finer the image. Fine
images, made up of lots of pixels (dots),
are important for detailed images.
Generally, 15” LCD monitors have
a maximum computer resolution of
1024x768 pixels. This would not be a
problem as a higher resolution would
result in text and icons being too small
to display properly on the screen. 17”
and above LCD monitors usually have
a maximum resolution of 1280x1024
pixels or 1600x1200 in some cases.

The number of pixels makes a
difference normally only if you are
involved in graphic design and need
high resolutions for creating very fine
images. If you need a resolution
of 1280x1024 then you need to
purchase at least a 17” monitor.
Please note, that if you know which
resolution you want to work at, then
make sure you get a screen with
exactly that number of pixels. For
example, don’t buy a screen with
1600x1200 pixels if you are going

Toshiba Ultra HD 4K display screens
Full HD v Ultra HD
Full HD (high definition) resolution
has 1920x1080 pixels which is
the equivalent of 2.1 megapixels.
This is a viewing aspect ratio of
16:9 and gives a widescreen
image and is the typical shape of
most commercial displays and
consumer TVs today.
Ultra HD has four times as many
pixels as Full HD (3840x2160) and
can deliver stunning picture quality,
regardless of screen size.
Traditionally, Full HD images
can begin to break up and lose
detail on TV screens of 55" or
140cm and above. With an
Ultra HD TV, you get incredible
resolution allowing you to enjoy
uncompromisingly crisp, clear
images and text - even when
sitting close to the screen.
Ultra HD is also known as 4k2k - and
is one of the most talked about and
desirable new technologies on the
market. This technology will have a
huge effect on how we watch things
in the future. This is because Ultra
HD delivers by far the most incredible
picture quality to date.
This will effect everything you watch
from movies to TV shows and from
documentaries to sports - all in new
levels of details.

Ultra HD is the equivalent quality of an
8mp image. Great for images taken
via digital cameras, smartphones or
even tablets. Plus, if connected to a

Inputs and connectors
When you want to connect your
computer to a TV or LCD monitor you
can use the analogue VGA connector,
or the digital connectors - DVI, HDMI
or DisplayPort. Not all of these ports
will be available on your LCD monitor
or TV as it depends on individual
makes and models. It is useful to
check the manufacturer’s specification
sheet prior to purchase.

The above picture shows a DVI port
on the left and a normal monitor (VGA)
port on the right.
The majority of TVs and many LCD
monitors have HDMI (high definition
multimedia interface). Being
multimedia it carries video and audio
DVI (digital video input) carries video
signals but not audio. As most LCD
monitors do not include speakers, this
isn’t likely to be a problem.
DisplayPort connector
DisplayPort is a video and audio
interface standard developed by and
for the personal computer industry as
the next generation A/V interface. It is
administered by the Video Electronics
Standards Association (VESA).
DisplayPort products currently support
up to 4K video, and the release of
DisplayPort 1.3 will enable higher
resolution including 5K monitors
(5120x2880), using a single cable.
The Thunderbolt connector now used
by Apple and others is also based
on DisplayPort, and Thunderbolt
is backwards-compatible with
DisplayPort cables and monitors. See for more information.
There are many solutions on the
market for splitting and distributing
signals. For example, CYP’s HDMI
1 to 2 distribution amplifier supports
4K resolutions. Besides splitting and
USB hubs
The picture on the left shows a 4 port
USB hub (Universal Serial Bus) on the
back of an LCD monitor. The picture
on the right shows a two port version.
In a normal computer set-up a mouse
and a keyboard are connected to the
computer. The mouse and keyboard
wires trail across the desk and back to
the computer, which could be on the
desk or under it. Most computers now
have USB keyboards and mice which
plug into a USB port on the computer.
Some LCD monitors have a USB
hub built-in, which is then connected
by a single USB cable back to the
computer base unit. You can then
connect your USB keyboard, USB
mouse, USB web cam, USB digital
camera, etc, into the monitor base.
The USB hub therefore simplifies your
cabling especially if the computer
base unit is ever removed for repair or
Edis mini PC
Devices such as digital signage
players (mini PCs) have USB
connectors, for the connecting
of a keyboard and mouse to
allow you to create your signage
presentation onto your LCD
monitor or large format display.
NEC rear speakers for LFD
Unlike televisions which include
speakers, most LCD monitors do
not come with speakers. Some
makes and models offer optional
speakers or soundbars.
A cable comes from the speakers
on the monitor to plug into the
speaker socket on the computer.

Energy saving and technology Warranties
Manufacturer warranties for consumer
televisions tend be a standard 1 year
RTB (Return to Base), which means
you return it to the repair centre.
iiyama light sensor feature
Most LCD desktop monitors and large
format displays (LFD) now have energy
saving features. You may see TCO
(total cost of ownership), followed by
a number, for example, TCO 5.0 This
tells you what level of energy saving
the LCD monitor is. This is a bit like the
A, B, C energy ratings you now see
when you buy a new fridge or washing
machine at home. Displays also have
to be less than a certain wattage when
on standby.
LED TVs and LED monitors are
actually LCD TVs and LCD monitors
with LED (light emitting diode) backlight. LEDs are energy saving,
economical and rather than the
old-style CCFL lighting, LEDs can be
controlled, therefore you see some
displays, such as iiyama ProLite large
format displays, have ambient light
sensors. The ambient light sensor
detects changes in environmental
lighting conditions and automatically
adjusts the screens backlight
brightness to compensate for and
increase or decrease in light. LED
TVs and LED monitors also are much
slimmer in design.
As technology develops and
continually improves, you will see
display manufacturers using different
technologies for their panels. For
example, the iiyama ProLite 65”
touch screen display uses AMVA3
technology. AMVA3 technology
offers higher contrast, darker blacks
and much better viewing angles
than standard TN (twisted nematic)
technology. The screen will look good
no matter what angle you look at it.
IPS panel technology also offers higher
contrast, with darker blacks and much
better viewing angles than standard
TN technology.
Another function available on LFDs
and most televisions, depending on
make and model, is PiP. PIP (Picture
in Picture) function allows you to watch
images coming from two different
sources at the same time.
iiyama display with PIP (Picture in Picture)
iiyama display with AMVA3 technology
Warranties on commercial LCD
monitors and large format displays,
are usually 2 year RTB or more.
Some manufacturers offer an on-site
warranty, which normally means a visit
to your premises within a set number
of hours to repair the display. C&R
(Collect and Repair) warranty is when
a courier collects the faulty display
and once repaired the manufacturer’s
repair centre will ship it back to you.
Swap-out warranty is where your faulty
display will be taken away and you are
given a replacement of similar model
and age as a swap.
For education, a manufacturer
warranty may be 3 year de/reinstall.
This means that the display will be
de-installed from its mounting, taken
away for repair and then re-installed.
This saves time and expense on the
educational establishment and gives
peace of mind for 3 years.
Many of the manufacturers of leading
brands of large format displays have
models in their range that are designed
for 24/7 (24 hours a day, 7 days a
week) applications, such as in airports
and 24/7 supermarkets. However, it
is important to read the manufacturer’s
warranty to check whether their
warranty does covers you if the LCD
monitor is in use for the full 24 hours
every day, or whether they recommend
it be switched off periodically.
NEC Displays, for instance, offer a
range of large format displays that
offer 24/7 or 16/7 warranties (16 hours
a day, 7 days a week). Ideal for cost
efficient retail signage, conferencing
applications and lobby or reception
installations not exceeding 16/7
operation time.
NEC also have models with 12/7
warranties. These are suitable for light
retail environments, such as leisure
and museums, hospitality, education
and conferencing applications.

format displays in their range that
allow you to change from landscape
(horizontal) to portrait (vertical) mode.
Portrait mode is especially useful
in medical training so that students
can view X-Rays and other medical
images. Museums can benefit from
using large format displays in portrait,
to bring history to life. Retail fashion
shows is another example.

3M™ privacy filters
Privacy filters keep information private.
When you walk into a high street bank
there is normally a privacy filter fitted
to the receptionist’s LCD monitor.
Teachers and school administration
staff working on sensitive data such
as students' personal information,
students' examination results, school
accounts and online banking, etc.,
may be interested to learn that
privacy filters are available for LCD
monitors, laptops and tablets to help
protect sensitive information from
unauthorised viewing.
In colleges and universities, libraries
and museums, where there are open
plan reception and office areas,
on-screen privacy may well be an
issue. The use of privacy filters is
beneficial during exam times as a lot
of exams are now moving down the
e-assessment (on-line examinations)
route. With guidelines that exist
stating that desks need to be placed a
certain distance apart and separated
by dividers, it can be an expensive
and laborious process for schools
to implement. Privacy filters offer an
easier and less expensive solution,
allowing more computers and
students in a smaller space (the filters
also comply with JCQ regulations).
3M™ have developed a black filter
to fit widescreen desktop monitors
available in varying sizes. With a
simple attachment system the filter
can be removed for screen sharing.
Using 3M™ microlouver technology
the filter gives you full 60 degree
privacy protection from either side
of the monitor, thus protecting your
information. The filter is available in
reversible glossy finish or matte finish,
the latter reduces discomfort from
screen glare. LCD desktop monitors
and touchscreens already fitted with
3M™ privacy filter are also available.
3M™ black privacy filters and gold
privacy filters are also available for
Notebook computers and Macbooks,
whilst 3M™ black privacy screen
protector is available for use on
Apple® iPad® 2/3/4, iPad Air and
iPad Mini. 3M™ gold privacy
filters offer nearly twice the privacy;
protecting from above and below, as
well as the side and offer 14% better
viewing clarity compared to the black
filters. They also appear a vibrant
gold colour from the side view, giving
an obvious privacy warning.
Furthermore, there is privacy
protection for tablets and mobile
phones. For dual orientation tablets
(landscape/portrait), you can keep
your information private or share it
with others by simply changing the
orientation of your tablet screen.

TouchGENiE touch screen overlays
attach to your monitor, transforming it
into a touch screen.
You attach the touch screen overlay to
your monitor using the strap provided,
plug the cable from the touch screen
overlay into a USB port in your
computer, and your monitor is now a
touch screen.
TouchGENiE have brought out a
range of touch screen overlays for
desktop screen sizes from 17” to large
format screens up to 132” diagonal.
These are available in various aspect
ratios, namely, 4:3, 16:9 and 16:10,
with either 2-point touch, 6-point
touch or 10-point touch when used
with Windows 7 or Windows 8/8.1.
Compatible with Windows, Mac and

LCD monitor and touch screen guide
Touch screens
NEC 65” touch screen
In this article we look at the uses of
touch screens and also the different
technologies available to make touch
screens “touchable”.
Touch screen technologies
This is primarily a guide to touch
screen monitors to be attached to a
PC and other computers.
From the first version of Windows and
with Apple computers, a mouse has
been used to control the mouse cursor
on the computer’s screen. Then touch
screen monitors became available,
which then allowed the mouse cursor
to be controlled by touching the
screen with either a finger or stylus
instead. Programmers could then
create programs/applications with
large buttons on screen and hide the
mouse cursor altogether when using
their programs, if necessary. Then
we got multi-touch, which allows
additional control by allowing more
than one finger to control the screen at
the same time. Movements such as
pinching the index finger and thumb
on the screen allowed the resizing of
pictures, etc. With the latest operating
systems, such as Windows 8, touch
screens are used with swipeing
motions on screen to scroll around.
The majority of us with mobile phones
have moved to smartphones with
Android or the iPhone. These also
have a touch screen interface, without
any sign of a mouse cursor in sight.
There are many different technologies
that are used to make screens into
touch screens. We are assuming that
many you reading this has a smart
phone, so let us start by looking at
the technology used in many phones
which then gives us a yard stick for
comparing the other technologies.
Capacitive technology
The majority of smart phones use
a capacitive technology. What this
means is that the screen has a small
electric current over the surface and
when you touch it with your finger
a circuit is created as your finger
conducts electric currents. If you have
ever tried to use your smart phone
with gloves on, then you will find
that it doesn’t work (unless you buy
special touch screen gloves). This is
because your finger is insulated within
the glove. This is the main draw back
of capacitive technology. You have
to either use a body part, or a special
stylus (that conducts electric) to use
it. You will also find that if it is raining
and you try to use your smartphone
that you have trouble if the screen
gets rain drops on or your fingers
are wet. This is because liquids and
moisture interferes with the capacitive
technology. That said, your phone will
Projected capacitive

be very sensitive and responsive and
allows you to use multi-touch gestures
(using more than one finger at a time)
to control the phone with ease.
There are basically two types of
capacitive technology - projected
capacitive sometimes known as PCAP,
and surface capacitive. The latter
tend to be used in large touch screen
panels, whilst projected capacitive is
often used in smaller screen sizes.
The iPhone and iPad, for example, use
projected capacitive technology.
OK, so hopefully you now (if you
have a smartphone) have a grasp of
capacitive technology. The next major
technology, that has been around for a
long time, is resistive technology.
Resistive Technology
Resistive touch screens are made by
having a hard but slightly flexible top
layer, then a small gap and another
layer underneath. When the flexible
layer is touched, it presses through
to the layer underneath so that the
touch screen knows where the screen
was pressed. The great thing about
this is that you don’t need a finger
like in the capacitive technology. You
can use practically anything to touch
the screen including gloved hands
or any kind of stylus. This is single
touch technology. On the downside,
since you are continually flexing the
front layer when touching it, then the
lifespan, i.e. the amount of times it can
be touched, is a lot lower as effectively
you have a moving part. The capacitive
technology is a lot longer lasting in that
Infrared (IR) Technology
Many of the first interactive
whiteboards on the market used ether
electromagnetic (pen) or resistive
(touch) technology. Infrared uses the
same technology as in your infrared
TV remote control at home to create
a curtain of light across the board’s
surface. You can use either a finger or
a stylus to operate the board and the
surface of the board can be replaced
if damaged, unlike resistive, which if
damaged is unusable.
Optical Touch Technology
Optical touch (or optical sensing)
technology has cameras in the
corner of the screen and a reflective
strip, so that it knows when you are
touching the screen. Some screens
have two cameras and others have
four cameras, one in each corner.
The bezel (surround) on optical
sensing touch screens is a little bigger
to incorporate the cameras. One
advantage of optically sensed touch
systems is that it can function with
light scratches and surface wear,
as can projected capacitive. Touch
is activated by bare fingers, gloved
fingers or a stylus.
Optical sensing technology is ideal
when handwriting annotation is
required. In the training room, an
optical sensing technology LCD touch
screen can also be used in the same
way as an interactive whiteboard.
Obviously, you would need touch
screen software.
In hospitals where regular cleaning
takes place, care is needed with the
cleansing of optical touchscreens as
the cameras in the corners tend to
collect dust.
Some universities and science
museums have installed “graffiti
walls”. These are basically large touch
screens that people scribble on by
controlling applications like Windows
Paint with their fingers to draw on.
Now the technology used by the touch
screen does make a big difference
here. Drawing a line with your finger on
any capacitive screen is fine, however
if you try to annotate this gives you a
jerky line. Optical sensing would be a
better choice, especially as sizes are
currently available up to 82” diagonal.
You would also need an annotation
package such as Windows Paint or a
bespoke annotation package.
Infrared Acrylic Projection
Infrared acrylic projection also uses
cameras to detect the positions of
touches on the screen. This is a
multi-touch technology and is used
in Microsoft PixelSense (Microsoft
Surface) and allows multiple users to
use a screen at the same time.
Dispersive Signal Technology
Dispersive Signal Technology (DST)
from 3M™, radiates bending waves
to Piezoelectric receptors around
the edge of the screen. It is mainly
used for annotation applications and
tabletop touch screens. You can put
your hand on the table touch screen
and it recognises that and would not
act as a mouse until you tapped the
touchscreen. The disadvantage of
bending wave is that it is not suitable
for drag and drop routines and external
vibration will interfere with the touch
operation. These are not affected by
dust or scratches on the surface of
the screen and allow any object to be
used to touch the screen including a
stylus. Table touch screens are used
in primary and early learning centres
where several children can touch and
move digital objects around, whilst
in bars and restaurants table touch
screens can be used to display menus
and drinks for customers to place
orders by swipeing across the table.

LCD monitor and touch screen guide
Single, dual and multi-touch
A single-touch screen is one that will
only detect a single position being
touched at one time. If you touch
this type of screen with more than
one finger then it will get confused.
With Windows based computers this
allows the control of the mouse cursor,
and the mouse cursor will follow your
finger around the screen. You can
use some touch gestures such as tap
(tap the screen once with your finger
to perform a single mouse click) or
double tap (where you tap the screen
twice in one location to simulate a
double mouse click).
Dual-touch is where a touch screen
will allow two (but no more) positions
on screen to be touched as once. If
you think about using a Windows
based notebook computer (before the
latest versions) then when you used
a touch pad on a laptop computer it
just controls the cursor’s position on
screen. This is a good example of
dual touch as most of these will allow
dual touch gestures. For example,
the pinch gesture where the thumb
and the index finger are placed on
the screen at the same time and
then ‘pinched’ together. This also
allows the zooming out when viewing
something like a website page, and
then ‘spread’ gesture is the opposite
of this where the thumb and index
finger and pinched together, then the
screen touched and then the thumb
and index finger and spread apart.
Multi-touch is where you can use 3 or
more fingers at a time. For example
the three-finger drag is where you
touch the top of the screen or a touch
pad with your 3 middle fingers (slightly
spread) and then drag these around
the screen and the selected object will
be moved with it.
Touch screens with interactive
whiteboard software
Large format LCD / LED Interactive
panels are available with touch pen,
eraser and pen annotation software
(interactive whiteboard software).
Interactive whiteboard (IWB) software
allows you to use the touch screen
in the same way as teachers do
with interactive whiteboards in the
classroom. It allows you to write over
the top of information displayed on
screen and then save your annotations
to a picture file on disk which can then
either be printed or emailed. This is a
good tool for brainstorming sessions
and meetings. Touch screens with
interactive whiteboard software
These can be a good choice for
schools rather than going for the
traditional whiteboards. The standard
interactive whiteboards use a projector
to shine the image on the screen. If a
teacher or child using the whiteboard
turns around, they may end up looking
into the projector’s light which can hurt
their eyes. Short throw and ultra short
throw projectors solve the problem of
light shining in your eyes and you can
purchase an interactive whiteboard
with short throw or ultra short
throw projector on a fixed or height
adjustable stand. Projectors also use
expensive projector lamps that will
require changing every few thousand
hours of use.
SMART Technologies, one of the
largest whiteboard manufacturers,
manufacture large touch screens with
their interactive whiteboard software
(SMART Notebook) included. If the
teachers in a school already use
SMART Boards, then changing to a
touch screen panel (display screen)
will mean the same software is used,
hence saving learning new software.
The main thing to weigh up is the cost
of an interactive projector and bracket;
an interactive whiteboard, projector,
projector bracket and on-going cost
of replacing projector bulbs; a large
format (60” diagonal or over) LCD /
LED interactive (touch screen) display
with interactive whiteboard software.
Other factors come into play, such as
ultra-short throw, room space, product
durability, quality of the interactive
software and budget. Don’t forget that
interactive whiteboards are just big
touch screens, even though you tend
to use touch or special pens and the
manufacturer’s interactive whiteboard
software. It’s the software that comes
with them that makes them useful for
class and meeting rooms.
Interactive whiteboards
Earlier models of interactive
whiteboards used either resistive or
electromagnetic technology. The latter
used special pens to transmit a signal
to the receiver in the whiteboard. The
downside to this is that because the
pens are electronic, they tended to be
expensive to replace and if you lose
the pens you can’t use the whiteboard.
The plus side is that you can replace
the surface if it gets damaged as the
electronics are in the pen and the
whiteboard’s surround.
Interactive whiteboards tend
nowadays to use Infrared or Optical
Sensing technology. Some interactive
whiteboards, such as PolyVision eno
are 3-in-1 boards, in that they can be
used as a standard dry-erase board, a
magnetic board, and with a projector
as an interactive whiteboard.
With whiteboards, the quality of the
software that is shipped with them
makes all the difference, rather than
the actual technology used. You
may find that a particular hospital,
university or business has all one make
of interactive whiteboards so that
you only need to learn one piece of
whiteboard software. ‘Open platform’
lets you run many other third party
software programmes. Whiteboards
Any other touch solutions?
Portable devices such as eBeam
and mimio turn dry-wipe boards
into interactive whiteboards. Some
manufacturers have interactive
projectors in their range, so you
can project large images onto most
surfaces such as plain white walls.

Touch screens in reception areas
Let’s imagine that you decide it is a
good idea to have a touch screen
on the wall in your reception area to
promote your products or services.
Your IT manager (or outsourced IT
company) may create the software,
which surprisingly can be made
with Microsoft PowerPoint, which
costs around £100+VAT in the UK.
PowerPoint presentations can be
created with buttons (so that someone
using a touch screen can easily
press them with their finger) that
allow the user to navigate between
different PowerPoint slides. You can
use videos, PDF’s, pictures, etc., in
PowerPoint slides, to create a good
information system quite easily.
The IT manager could look at other
commercial touch screen software or
by programming it with software such
as Microsoft Visual Basic, but this may
be quite costly either in terms of the
cost of software or the time it takes to
write a program.
Next, a computer base unit is needed
to play the touch screen presentation,
which could be an old one laying
around (it would need Windows®
XP, Vista or Windows® 7/8) or you
could use a digital signage player.
Some signage players have Windows
Embedded software, which is a
cut-down version of a full Windows®
operating system and is normally
found in small mobile devices such as
signage players. Windows Embedded
Pro 8.1, for example, is designed
specifically for building automated
solutions and embedded devices,
such as kiosks, medical devices and
digital signage solutions.
Then the touchscreen itself is needed.
This will look like any other LCD
monitor but will also have a mouse
cable that goes back to the computer
base unit. This cable sends back
where the user has touched on the
screen, so that the computer knows
where the mouse cursor should be.
You can now start searching the
Internet looking at different touch
screens which will usually range in size
from 15” to 84” diagonal. A good 17”
on the reception desk may do the job
costing around £300+VAT. Whilst a
42” touch screen used for way finding
in a large reception area will cost from
£990+VAT upwards. Touch screens.
The size of the screen is really going to
be determined by your budget. So you
narrow it down to the size and screens
you can afford. Then you come to the
choice of different technologies.
Which technology do I choose for
the reception area touch screen?
In this example, as your visitors using it
will be in a nice warm reception waiting
area and using their fingers, then it
really doesn’t matter. Go for one within
your budget, as large as you can
afford and with the best warranty. Look
for a warranty with 3 years (or better)
and with the highest number of pixels
in your price range. The other thing
to watch out for is the cable type. We
mentioned that you need a “mouse
cable” going back to the computer.
You need to make sure the touch
screen uses USB, which will work
with all your computers, unless you
specifically need serial and understand
the difference.
Keep in mind that touch screens
are not vandal proof and should be
installed in areas that are monitored.
By monitored, we mean areas where
there are usually members of staff,
such as in a reception area. Some
touch screens have reinforced glass
and although the glass is vandal
resistant the actual product isn’t. Even
the touch screen kiosks you may
have seen in shopping centres are not
completely vandal proof. Here too, a
shopping centre is a monitored area,
often with security guards and CCTV.
You can buy protective overlays but
these do not work with touch screens.
There are LCD touch screen kiosks
sealed for weather resistance with
protective glass to deter vandalism,
ideal for unsupervised public areas.
What if I want a video wall of
touch screens?
Video walls are made of multiple
screens either close together such as
a 2x2 video wall which has 4 screens
(or a matrix of various size screens).
The computer or video image is then
spread across all of the screens. The
downside is that there is a small gap
between screens. When you watch
the news on a TV channel, you often
see presenters standing in front of a
giant screen, but when you look at the
screen you can see lines which are the
gaps between the screens that make
up the video wall. The size of the bezel
(surround) determines how big a gap
you get between the screens. Some
manufacturers have LCD screens
which are almost seamless.
What happens if I need to wear
surgical or disposable gloves?
If you are installing touch screens
in areas such as a biology lab in a
university teaching hospital, then you
would need to choose the technology
carefully. Using a touchscreen to
control a computer, instead of using a
keyboard and mouse, in areas where
medical style gloves are needed,
then out goes surface capacitive
technology as gloves will not give the
conduction that they need. In this
situation, you are left with Resistive,
Projected Capacitive or Optical
Sensing Technology. Optical Touch
and Projected capacitive are normally
available in screen sizes 32” to 84”.
Surface Capacitive touch technology
allows only single touch and is used
on small screens up to 32” diagonal.
Surface Capacitive touch technology
has been around for a long time
and is mainly used for public access
applications and contaminant prone
environments. This is because it is
largely unaffected by contaminants
such as grease, dirt and water. Whilst
this is good in biology labs or medical
teaching hospitals, the disadvantage
is it supports only finger touch (no
gloves) or a tethered pen and a severe
scratch can affect operation in the
damaged area.

Create eye-catching displays with multi-screen video walls
whilst multiple desktop monitors expand your working space
Multi-screen LCD monitors allow
you to expand the working space
on your computer. A good
example would be that you can
have a dual screen monitor with
Microsoft Word running on one
screen and Microsoft Excel on
another screen.
Usually when you are working with two
programs, you have to switch between
them when working. A two screen
multiple LCD monitor would allow you
to see both at the same time. Two
Microsoft Word documents could also
be displayed which would allow you to
read one while working on the other.

Imagine a computer is running three
programs: Word, Excel and Windows
Explorer, all at the same time on
different screens, you can then copy
and paste information between
programs with ease.
Extending the Windows desktop
onto multiple monitors
You need to have two monitors (or
more) monitors attached to your
system to be able to do this.
Desktop computers - connecting
additional monitors
Many new desktops come with two
ports on the graphics card, either VGA,
DVI or HDMI. You can plug monitors
into each of these. If you only have a
single monitor port, then you can either
replace the existing graphics card with
a dual port one, or in some cases you
could install a second graphics card.
Most local computer shops will be able
to do this for you if you do not have an
IT Department.
