VERSUS DLP
WHY 3LCD IS BRIGHTER THAN DLP3
­–
EVERYTHING’S BRIGHTER WITH EPSON
1-chip DLP projectors shine light through red, green,
blue and white5 segments of a spinning colour wheel
– These colour bursts must be combined by the viewer’s
brain to perceive the intended colour
No-one sells more projectors than Epson. Why? All our
projectors have an equally high WLO and CLO to ensure
everything’s bright.
– This results in a loss of brightness, and some viewers
can perceive the individual colours, instead of the
intended colour. This is called ‘colour break-up’, or
the ‘rainbow effect’
In fact, our projectors’ colours are up to three times
brighter1 than 1-chip DLP3 projectors.
– Epson’s 3LCD system combines red, green and
blue image portions and projects them as a single-full
colour image
98% SAY WE’RE BRIGHTEST
Don’t just take our word for it. In a blind test conducted
with an Epson projector against five other 1-chip DLP
brands with similar quoted lumens of white light, 95 per
cent of people surveyed said that the Epson projector
had the most vivid colours, and 98 per cent said we
have the brightest picture overall4.
– As the final colour is perfectly blended before being
projected, the result is a stable, true-to-life image that’s
easier on the eyes

Compared to leading 1-chip DLP home entertainment projectors. Epson 720p projectors are three times brighter; Epson 1080p projectors
are consistently two and up to three times brighter. Based on NPD data, July 2011 through June 2012. Colour brightness (Colour Light Output)
measured in accordance with IDMS 15.4. Colour brightness will vary depending on usage conditions. For more information please visit

RS Consulting, March 2013, base sample n200. 5 Some 1-chip DLP™ projectors do not contain white but contain other colours. 6 Data source:
ProjectorCentral.com Jan. 2012. Average of 1,122 shipping models for which the manufacturers provided lumens and total power data for all
resolutions and brightness levels. Energy efficiency was measured as wattage per lumen. It was measured for both 3LCD and 1-chip projectors
in each of five brightness segments. 3LCD projectors averaged less required electricity per lumen in each of the five segments.

Low maintenance – 3LCD runs at relatively low
temperatures and has virtually no moving parts to
repair or replace

WHAT IS CLO?
WHY IS CLO IMPORTANT?
WHAT IS COLOUR LIGHT OUTPUT?
WHY COLOUR IS CRITICAL?
When choosing a projector, you already know that it’s
important to find out its brightness, which is the main
figure quoted in lumens. But did you know you should
also check its Colour Brightness?
With today’s high-quality, high-resolution digital content,
the ability to reproduce colour and detail accurately is
more important than ever. After all, you’ve worked hard on
your presentation, so you want your audience to get the
full picture.
Colour Brightness is a global standard that scientifically
measures a projector’s Colour Light Output (CLO).
Projectors blend red, blue and green light to create colour
images, and it’s the brightness of these three colours that
is measured to give the CLO figure.
THE BENEFITS OF
EQUALLY HIGH WLO
AND CLO
1
Colour is an important part of image quality. If a projector’s
CLO is not as bright as its WLO, coloured images are likely
to appear dull and washed-out.
2
DOES ‘LUMENS’ INCLUDE
COLOUR BRIGHTNESS?
No. Unless you see a separate specification for Colour
Brightness or CLO, the lumens figure will only give
you the White Brightness of the projector. The Colour
Brightness could be much lower than the White
Brightness – so high lumens does not necessarily mean
high brightness overall.
WHAT SHOULD I LOOK OUT FOR?
Look for two separate measurements in lumens – one
for Colour Light Output (CLO), and one for White Light
Output (WLO).
MAKING A BETTER CHOICE
Not all digital projectors produce colour in the same way.
This means there’s a big difference in their CLO.
Many manufacturers only quote the brightness of their
projector’s white light – usually the main figure shown in
lumens in the projector’s spec. However, this only tells
you how bright a projector is when showing a plain white
image, which can be misleading.
If you know the CLO of a projector, then you can
make a much more accurate assessment of its overall
performance, and a more informed purchase decision.
For the optimum projected images with vibrant colour
and crisp detail, you should select a projector with an
equally high CLO and WLO.
Epson Example
1-Chip DLP example
Accurate colours that can be instantly
identified – essential for education, medicine,
training, artists, photographers and anyone
who wants their presentation to look exactly
as intended
Brighter images that make a
bigger impact
3
Clearer details that are easier to see
4
Flexibility to present in different light
conditions – thanks to brighter images, you
can keep the blinds open and the lights on
so your audience isn’t struggling to take notes
in the dark
5
More for your money – when WLO
and CLO are the same, the image is brighter
overall, meaning you don’t have to buy a more
expensive projector with very high WLO to
benefit from a bright projection
