doc no.: 44087341 issued date: sep, 23, 2008 model no.: n121ib - l06 approval 23 / 28 version 2.0 9. precautions 9.1 assembly and handling precautions (1) the module should be assembled into the system fi rmly by using every mounting hole. be careful not to twist or bend the module. (2) while assembling or installing modules, it can only be in the clean area. the dust and oil may cause electrical short or damage the polarizer. (3) use fingerstalls or soft gloves in order to keep display clean during the incoming inspection and assembly process. (4) do not press or scratch the surface harder than a hb pencil lead on the panel because the polarizer is very soft and easily scratched. (5) if the surface of the polarizer is dirty, please clean it by some absorbent cotton or soft cloth. do not use ketone type materials (ex. acetone), ethyl alcohol, toluene, ethyl acid or methyl chloride. it might permanently damage the polarizer due to chemical reaction. (6) wipe off water droplets or oil immediately. staining and discoloration may occur if they left on panel for a long time. (7) if the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. in case of contacting with hands, legs or clothes , it must be washed away thoroughly with soap. (8) protect the module from static electricity, it may cause damage to the c-mos gate array ic. (9) do not disassemble the module. (10) do not pull or fold the lamp wire. (11) pins of i/f connector should not be touched directly with bare hands. 9.2 safety precautions (1) the startup voltage of backlight is approximat ely 1000 volts. it may cause electrical shock while assembling with converter. 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. 9.3 operation precautions (1) do not pull the i/f connector in or out while the module is operating. (2) always follow the correct power on/off sequence when lcd module is connecting and operating. this can prevent the cmos lsi chips from damage during latch-up. (3) the startup voltage of backlight is approximat ely 1000 volts. it may cause electrical shock while assembling with converter. do not disassemble the module or insert anything into the backlight unit. 9.4 other precautions (1) when fixed patterns are displayed for a long time, remnant image is likely to occur. www.datasheet.co.kr datasheet pdf - http://www..net/
