(b) when the effective ignition length becomes ?? 80% of its original value. (the effective ignition length is a scope that luminance is over 70% of that at the center point.) note (5) p l = i l ?? v l ?? 2 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 generating 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 hv ( black ) hv ( blue ) lv ( white ) hv ( red ) lcd module 1 2 1 2 inverter a a ta = 252 j a current meter yokogawa 2016 www.datasheet.net/ datasheet pdf - http://www..co.kr/

doc no.: 44085408 issued date: nov. 12, 2008 model no.: n184h4 - l04 approval 24 / 29 version 2.1 8. precautions 8.1 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 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. 8.2 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 mo dule 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. www.datasheet.net/ datasheet pdf - http://www..co.kr/
