(b) when the effective ignition length becomes 80% of its original value. ?? (the effective ignition length is a scope that luminance is over 80% of that at 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 1 a hv (pink) 2 lv (white) oscillosco p e current amplify current probe 1 a hv (pink) 2 lv (white) lcd module inverter www.datasheet.co.kr datasheet pdf - http://www..net/

doc no.: 400028698 issued date: feb. 23, 2009 model no.: M190A1-L0G approval 16 / 25 version 2.0 6.2 power on/off sequence to prevent a latch-up or dc operation of lcd module, the power on/off sequence should be as the diagram below. timing specifications: 0.5< t1 ?? 10 msec 0 < t2 ?? 50 msec 0 < t3 ?? 50 msec t4 ? 500 msec t5 ? 450 msec t6 ? 90 msec 5 ?? t7 ?? 100 msec note. (1) the supply voltage of the external system for the modul e input should be the same as the definition of vcc. (2) apply the lamp voltage within the lcd operatio n range. when the backlight turns on before the lcd operation of the lcd turns off before the backlight tu rns 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 off and on period. (5) interface signal shall not be kept at high impedance when the power is on. (6) cmo won?t take any responsibility for the products which are damaged by the customers not following the power sequence. (7) there might be slight electronic noise when lcd is turned off (even backlight unit is also off). to avoid this symptom, we suggest "vcc falling timing" to follow "t7 spec" 50% 50% t6 t5 on off off valid data 10% t4 t3 90% - power supply for lcd, vcc - interface signal (lvds signal of transmitter), v i - power for lamp restart power on power off 0v 0v t2 t1 10% 90% 10% t7 www.datasheet.co.kr datasheet pdf - http://www..net/

(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. 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 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. 10.3 safety standards the lcd module should be certified with safety regulations as follows: (1) ul60950-1 or updated standard. (2) iec60950-1 or updated standard. 10.4 other when fixed patterns are displayed for a long ti me ,remnant image is likely to occur. www.datasheet.co.kr datasheet pdf - http://www..net/
