Note (1) There should be no condensation on the surface of panel during test.
Note (2) Temperature of panel display surface area should be 90 ºC Max.
Note (3) 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.
Note (4) In the standard conditions, there is no function failure issue occurred. All the cosmetic specification
is judged before reliability test.

5.3 COLOR DATA INPUT ASSIGNMENT
The brightness of each primary color (red, green and blue) is based on the 6-bit gray scale data input for
the color. The higher the binary input, the brighter the color. The table below provides the assignment of
color versus data input.

Note (1) Please avoid floating state of interface signal at invalid period.
Note (2) When the interface signal is invalid, be sure to pull down the power supply of LCD Vcc to 0 V.
Note (3) The Backlight inverter power must be turned on after the power supply for the logic and the
interface signal is valid. The Backlight inverter power must be turned off before the power supply
for the logic and the interface signal is invalid.

Note (2) Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following expression.
Contrast Ratio (CR) = L63 / L0
L63: Luminance of gray level 63
L 0: Luminance of gray level 0
CR = CR (5)
CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (6).

Note (4) Definition of Luminance of White (LC):
Measure the luminance of gray level 63 at center point
LC = L (5)
L (x) is corresponding to the luminance of the point X at Figure in Note (6).
Note (5) Measurement Setup:
The LCD module should be stabilized at given temperature for 20 minutes to avoid abrupt
temperature change during measuring. In order to stabilize the luminance, the measurement
should be executed after lighting Backlight for 20 minutes in a windless room.

10. PRECAUTIONS
10.1 ASSEMBLY AND HANDLING PRECAUTIONS
(1) Do not apply rough force such as bending or twisting to the module during assembly.
(2) To assemble or install module into user’s system can be only in clean working areas. The dust and oil
may cause electrical short or worsen the polarizer.
(3) It’s not permitted to have pressure or impulse on the module because the LCD panel and Backlight
will be damaged.
(4) Always follow the correct power sequence when LCD module is connecting and operating. This can
prevent damage to the CMOS LSI chips during latch-up.
(5) Do not pull the I/F connector in or out while the module is operating.
(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) It is dangerous that moisture come into or contacted the LCD module, because moisture may damage
LCD module when it is operating.
(9) High temperature or humidity may reduce the performance of module. Please store LCD module
within the specified storage conditions.
(10) When ambient temperature is lower than 10ºC may reduce the display quality. For example, the
response time will become slowly, and the starting voltage of CCFL will be higher than room
temperature.
(11) Do not keep same pattern in a long period of time. It may cause image sticking on LCD.
10.2 SAFETY PRECAUTIONS
(1) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while
assembling with 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.
