Note (2) The lamp starting voltage VS should be applied to the lamp for more than second after startup. Otherwise the lamp may not be turned on. Note (3) The lamp frequency may produce interference with horizontal synchronous frequency of the display input signals, and it may result in line flow on the display. In order to avoid interference, the lamp frequency should be detached from the horizontal synchronous frequency and its harmonics as far as possible. Note (4) The lifetime of lamp can be defined as the time in which it continues to operate under the condition Ta = 25 2 o C and I L = 7 marms until one of the following events occurs (a) When the brightness becomes or lower than 5% of its original value. (b) When the effective ignition length becomes 8% of its original value. (The effective ignition length is a scope that luminance is over 7% of that at the center point.) 4. BLOCK DIAGRAM 4.

(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. () When ambient temperature is lower than ºC, 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. () Do not keep same pattern in a long period of time. It may cause image sticking on LCD..2 SAFETY PRECAUTIONS () The startup voltage of a Backlight is approximately 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. 24
