issued date: dec. 19, 2001 model no.: m170e4 -l01 approval 10 / 28 version 2.3 note (2) the voltage shown above should be applied to the lamp for more than 1 second after startup. otherwise the lamp may not be turned on. note (3) the lamp frequency may produce interference with horizontal synchronous frequency from the display, and this may cause line flow on the display. in order to avoid interference, the lamp frequency should be detached from the horizontal sy nchronous frequency and its harmonics as far as possible. note (4) p l = i l v l note (5) 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 = (2.0) ~ (6.5) marms until one of the following events occurs: (a) when the brightness becomes or lowe r than 50% of its original value. (b) when the effective ignition length becomes or lower than 80% of its original value. (effective ignition length is defined as an area that ha s less than 70% brightness compared to the brightness in the center point.) note (6) the waveform of the voltage output of inverter must be area-symmetric and the design of the inverter must have specifications for the modularized lamp. the performance of the backlight, such as lifetime or brightness, is greatly influenced by the characteristics of the dc-ac inverter for the lamp. all the parameters of an inverter s hould be carefully designed to avoid producing too much current leakage from high voltage output of the inverter. when designing or ordering the inverter please make sure that a poor lighting ca used by the mismatch of the backlight and the inverter (miss-lighting, flicker, etc.) never occu rs. if the above situation is confirmed, the module should be operated in the same manners when it is installed in your instrument.

(1) the supply voltage of the external system for the m odule input should be the same as the definition of vcc. (2) apply the lamp voltage within the lcd operation range. when the backlight turns on before the lcd operation of the lcd turns off before the backlight turns off, the display may momentarily become abnormal screen. (3) in case of vcc = off level, please keep the level of input signals on the low or keep a high impedance. (4) t4 should be measured after the module has been fully discharged between power of and on period. (5) interface signal shall not be kept at high impedance when the power is on.

issued date: dec. 19, 2001 model no.: m170e4 -l01 approval 26 / 28 version 2.3 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 shor t 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 c ontacted the lcd module, because moisture may damage lcd module when it is operating. (9) high temperature or humidity may reduce the per formance 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 slow ly, and the starting voltage of ccfl will be higher than room temperature. 10.2 safety precautions (1) the startup voltage of backlight is approximat ely 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.
