Unit Note
Min. Max.
(c) No condensation.
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.
Note (3) 11 ms, half sine wave, 1 time for ± X, ± Y, ± Z.
Note (4) 10 ~ 200 Hz, 10 min, 1 time each X, Y, Z.
Note (5) At testing Vibration and Shock, the fixture in holding the module has to be hard and rigid enough so
that the module would not be twisted or bent by the fixture.

2.2 PACKAGE STORAGE
When storing modules as spares for a long time, the following precaution is necessary.
(a) 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 35 к at normal humidity without condensation.
(b) The module shall be stroed in dark place. Do not store the TFT-LCD module in direct sunlight or fluorescent
light.

5.3 COLOR DATA INPUT ASSIGNMENT
The brightness of each primary color (red, green and blue) is based on the 8-bit gray scale data input for the color.
The higher the binary input, the brighter the color. The table below provides the assignment of the color versus
data input.

Note (1) The supply voltage of the external system for the module input should follow the definition of Vcc.
Note (2) Apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD
operation or the LCD turns off before the backlight turns off, the display may momentarily become
abnormal screen.
Note (3) In case of Vcc is in off level, please keep the level of input signals on the low or high impedance.
Note (4) T4 should be measured after the module has been fully discharged between power off and on period.
Note (5) Interface signal shall not be kept at high impedance when the power is on.

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 ] When storing modules as spares for a long time, the following precaution is necessary.
[ 9.1 ] 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 35кat normal humidity without
condensation.
[ 9.2 ] The module shall be stored in dark place. Do not store the TFT-LCD module in direct sunlight or
fluorescent light.
[ 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 approximately 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.
