Notes : 1) Temperature and relative humidity range is shown in the figure below.
(a) 90 %RH Max. (Taİ40 ºC).
(b) Wet-bulb temperature should be 39 ºC Max. (Ta > 40 ºC).
(c) No condensation.
Unit Note
2) The maximum operating temperature is based on the test condition that the surface
temperature of display area is less than or equal to 65 ºC with LCD module alone in a
temperature controlled chamber. Thermal management should be considered in final
product design to prevent the surface temperature of display area from being over 65 ºC.

The range of operating temperature may degrade in case of improper thermal management
in final product design.
3) The rating of environment is base on LCD module. Leave LCD cell alone, this environment
condition can’t be guaranteed. Except LCD cell, the customer has to consider the ability
of other parts of LCD module and LCD module process.

Note (3) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) = L255 / L0
L255: Luminance of gray level 255
L 0: Luminance of gray level 0
CR = CR (5), where CR (X) is corresponding to the Contrast Ratio of the point X at the figure
in Note (6).
Note (4) Definition of Gray to Gray Switching Time:
The driving signal means the signal of gray level 0, 123, 168, 202, 230, 255. Gray to gray average
time means the average switching time of gray level 0, 123, 168, 202, 230, 255 to each other.
Note (5) Measurement Setup:
The LCD module should be stabilized at given temperature for 60 minutes to
avoid abrupt temperature change during measuring. In order to stabilize the luminance,
the measurement should be executed after lighting Backlight for 60 minutes in a windless room.

Note (6) Definition of White Variation (W):
Measure the luminance of gray level 255 at 5 points
W = Maximum [L (1), L (2), L (3), L (4), L (5)] / Minimum [L (1), L (2), L (3), L (4), L (5)]
where L (X) is corresponding to the luminance of the point X at the figure below.

8. PRECAUTIONS
8.1 ASSEMBLY AND HANDLING PRECAUTIONS
1) Do not apply rough force such as bending or twisting to the module during assembly.
2) It is recommended to assemble or to install a module into the user’s system in clean working areas.
The dust and oil may cause electrical short or worsen the polarizer.
3) Do not apply pressure or impulse to the module to prevent the damage of LCD panel and
backlight.
4) Always follow the correct power-on sequence when the LCD module is turned on. This can
prevent the damage and latch-up of the CMOS LSI chips.
5) Do not plug in or pull out the I/F connector while the module is in operation.
6) Do not disassemble the module.
7) Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft
and easily scratched.
8) Moisture can easily penetrate into LCD module and may cause the damage during operation.
9) High temperature or humidity may deteriorate the performance of LCD module. Please store LCD
modules in the specified storage conditions.
10) When ambient temperature is lower than 10ºC, the display quality might be reduced. For
example, the response time will become slow, and the starting voltage of CCFL will be higher than
that of room temperature.
8.2 SAFETY PRECAUTIONS
1) The startup voltage of a backlight is over 1000 Volts. It may cause an electrical shock while
assembling with the inverter. Do not disassemble the module or insert anything into the backlight unit.
2) 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, skin or clothes, it has to be washed away thoroughly with soap.
3) After the module’s end of life, it is not harmful in case of normal operation and storage.
8.3 STORAGE PRECAUTIONS
When storing modules as spares for a long time, the following precaution is necessary. 1) Do not
leave the module in high temperature, and high humidity for a long time. It is highly
recommended to store the module with temperature from 0 to 35ćat normal humidity without
condensation.
2) The module shall be stored in dark place. Do not store the TFT-LCD module in direct sunlight or
fluorescent light.
