5.3 RELATIONSHIP BETWEEN DISPLAY COLORS AND INPUT SIGNALS
The brightness of each primary color(red,green,blue) is based on the 10-bit gray scale data input for the
color. The higher binary input, the brighter the color. Table 6 provides a reference for color versus data
input.

9. PRECAUTIONS
9.1 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.
9.2 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.
9.3 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 35℃at 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.
