General Description
Description
LTM215HT04 is a color active matrix liquid crystal display (LCD) that uses amorphous
silicon TFT (Thin Film Transistor) as switching components. This model is composed of
a TFT LCD panel, a driver circuit and a back light unit. The resolution of a 21.5” is 1920
x 1080 and this model can display up to 16.7 millions colors.
Features
 High contrast ratio, high aperture structure
 High speed response
 FHD(1920 x 1080 pixels) resolution
 White LED Edge slim Backlight (Vertical)
 DE (Data Enable) only mode
 LVDS (Low Voltage Differential Signaling) interface (2pixel/clock)
 RoHS,
RoHS Halogen Free
 TCO 5.1 compliance
(Except for 2.2 Response time; this product does not have over driving function.
It is recommended to support in system level.)

c. Test method
-1st gray step : move a square of 255 gray level should be moved into the center of the
screen and measure luminance and u’ and v’ coordinates.
- Next gray step : Move a 225 gray square into the center and measure both
luminance and coordinates, too.
F
d. Test evaluation
u' v' = (u' A - u' B) 2 + (v' A - v' B) 2
Where A, B : 2 gray levels found to have the largest color differences between them
i.e. get the largest ∆u’ and ∆v’ of each 6 pair of u’ and v’ and calculate the ∆u’v’.

8. General Precautions
8.1 Handling
(a) When the module is assembled,
assembled it should be attached to the system firmly
using all mounting holes. Be careful not to twist and bend the module.
(b) Because the inverter uses high voltages, it should be disconnected from power
source before it is assembled or disassembled.
(c) Refrain from strong mechanical shock and / or any force to the module.
In addition to damage
damage, it may cause improper operation or damage to the module
and CCFT back light.
(d) Note that polarizer films are very fragile and could be damaged easily.
Do not press or scratch the surface harder than a HB pencil lead.

(e) Wipe off water droplets or oil immediately. If you leave the droplets for a long
time staining or discoloration may occur

(f) If the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth.
(g) Desirable cleaners are water, IPA (Isopropyl Alcohol) or Hexane.
Do not use Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid
or Methyl chloride. It might cause permanent damage to the polarizer due to chemical
reaction.
reaction
(h) If the liquid crystal material leaks from the panel, it should be kept away
from the eyes or mouth . In case of contact with hands, legs or clothes, it must
be washed away with soap thoroughly.
(i) Protect the Module from static, or the CMOS Gate Array IC would be damaged.
F
(j) Use finger-stalls with soft gloves in order to keep display clean during the
incoming inspection and assembly process.
(k) Do not disassemble the Module.

(m) Protection film for polarizer on the Module should be slowly peeled off just
before use so that the electrostatic charge can be minimized.
(n) Pins of I/F connector should not be touched directly with bare hands.

PRODUCT INFORMATION
8.4 Operation Condition Guide
(a) The LCD product should be operated under normal conditions.
Normal condition is defined as below;
- Temperature : 20±15℃
- Humidity : 65±20%
- Display pattern : continually changing pattern (Not stationary)
(b) If the product will be used in extreme conditions such as high temperature,
humidity, display patterns or operation time etc.., It is strongly recommended
to contact SEC for Application engineering advice. Otherwise, its reliability and
function may not be guaranteed. Extreme conditions are commonly found at
Airports, Transit Stations, Banks, Stock market, and Controlling systems.

8.5 Others
(a) Ultra-violet ray filter is necessary for outdoor operation.
(b) Avoid condensation of water. It may result in improper operation or disconnection
of electrode.
electrode
(c) Do not exceed the absolute maximum rating value. ( supply voltage variation,
input voltage variation, variation in part contents and environmental temperature,
and so on)
Otherwise the Module may be damaged.
F
(d) If the Module keeps displaying the same pattern for a long period of time,
the image may be "sticked" to the screen.
To avoid image sticking, it is recommended to use a screen saver.
(e) This Module has its circuitry PCB's on the rear side and should be handled
carefully in order not to be stressed.
(f) Please contact SEC in advance when you display the same pattern for a long time.
