product specification 10 / 24 EG121X1-L02-THA liquid crystal display ver0.1 dec. 08, 2008 bi-search international, inc. display solutions company 4. the output of the led driver must have symmetrical(negative and positive) voltage waveform and symmetrical current waveform.(unsymmetrical ratio is less than 10%) please do not use the led driver which has unsymmetrical voltage and unsymmetrical current and spike wave. led frequency may produce interface with horizontal synchronous frequency and as a result this may cause beat on the display. therefore led frequency shall be as away possible from the horizontal synchronous frequency and from its harmonics in order to prevent interference. 5. let?s define the brightness of the led after being lighted for 5 minutes as 100%. t s is the time required for the brightness of the center of the led to be not less than 95%. 6. the led power consumption shown above does not include loss of external led driver. the used led current is the led typical current. 7. the life is determined as the time at which bri ghtness of the led is 50% compared to that of initial value at the typical led current on c ondition of continuous operating at 25 2 ? c. 8. do not attach a conducting tape to led connecting wire. if the led wire attach to a conducting tape, tf t-lcd module has a low luminance and the led driver has abnormal action. because leakage current is occurred between led wire and conducting tape. note : the design of the led driver must have specification for the led in lcd assembly. the performance of the led in lcm, for example life time or brightness, is extremely influenced by the characteristics of the dc-dc led driver. so all the parameters of an led driver should be carefully designed so as not to produce too much leakage current from high-voltage output of the led driver. when you design or order the led driver, please make sure unwanted lighting caused by the mismatch of the led and the led driver(no lighting, flicker, etc) never occurs. when you confirm it, the lcd assembly should be operated in the same condition as installed in you instrument. 1. the specified current and pow er consumption are under the v cc =3.3v, 25 ? c,f v =60hz condition whereas mosaic pattern is displayed and f v is the frame frequency. 2. the variance of the voltage is 10%. 3. the voltage above v s should be applied to the leds for more than 1 second for start-up. otherwise, the leds may not be turned on. the used led current is the led typical current. www.datasheet.co.kr datasheet pdf - http://www..net/

product specification 22 / 24 EG121X1-L02-THA liquid crystal display ver0.1 dec. 08, 2008 bi-search international, inc. display solutions company 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 impuls e on the module because the lcd panel and backlight will be damaged. (4) always follow the cor r ect power sequence when lc d 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 performance of module. please store lcd module within the specified storage conditions. (10) when ambient temperature is lower than 10 c may reduce the display quality. for example, the response time will become slowly, and the starting volt age of led will be higher than room temperature. 10.2 safety precautions (1) the startup voltage of backlight is approximately 1000 volts. it may cause electrical shock while assembling with led driver. do not disassemble the m odule 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.co.kr datasheet pdf - http://www..net/
