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 10C 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.
