MODULE PRECAUTIONS
1. PRECAUTIONS
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 10
º
C, 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.
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.
