(b) because the inverter use high voltage, it shoul d be disconnected from power before it is assembled or disassembled. (c) refrain from strong mechanical shock and / or a ny force to the module. in addition to damage, this may cause improper oper ation or damage to the module and ccft back light. (d) note that polarizers are very fragile and could be damage easily. do not press or scratch the surface harder than a h b pencil lead. (e) wipe off water droplets or oil immediately. if you leave the droplets for a long time, staining or discoloration may occur. (f) if the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth. (g) desirable cleaners are water, ipa(isopropyl alc ohol) or hexane. do not use ketone type materials(ex. acetone), ethy l alcohol, toluene, ethyl acid or methyl chloride. it might permanent damage to th e polarizer due to chemical reaction. (h) if the liquid crystal material leaks from the p anel, it should be kept away from the eyes or mouth . in case of contact with ha nds, legs or clothes, it must be washed away with soap thoroughly. (i) protect the module from electrostatic discharge . otherwise the asic ic or semiconductor would be damaged. (j) use finger-stalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (k) do not disassemble the module. (l) do not disassemble shield case of inverter & lv ds board (m) do not connect n.c pins. (samsung internal use only) (n) protection film for polarizer on the module sho uld be slowly peeled off just before use so that the electrostatic charge can be minimized. must put on antistatic glove while handling a module (o) pins of i/f connector should not be touched dir ectly with bare hands. www..net www..net

(b) do not store the tft-lcd module in direct sunli ght. (c) the module should be stored in a dark place. it is prohibited to apply sunlight or fluorescent light in storing. 9.3 operation (a) do not connect or disconnect the module in the "power on" condition. (b) power supply should always be turned on/off by the "power on/off sequence" (c) module has high frequency circuits. sufficient suppression to the electromagnetic interference should be done by system manufacturers . grounding and shielding methods may be important to minimize the interference. (d) the cable between the back light connector and its inverter power supply should be connected directly with a minimized length. a lo nger cable between the back light and the inverter may cause lower lum inance of lamp(ccft) and may require higher startup voltage(vs). 9.4 operation condition guide (a) the lcd product should be operated under normal conditions. normal condition is defined as below; - temperature : 20 15 - humidity : 55 20% - display pattern : continually changing pattern (no t stationary) (b) if the product will be used in extreme conditio ns such as high temperature, humidity, display patterns or operation time etc.., it is strongly recommended to contact sec for application engineering advice. otherwise, its reliability and function may not be guaranteed. extreme conditions are commonly found at airports, transit stations, banks, stock market, an d controlling systems. www..net www..net

(b) avoid condensation of water. it may result in i mproper operation or disconnection of electrode. (c) do not exceed the absolute maximum rating value . ( supply voltage variation, input voltage variation, variation in part contents and environmental temperature, and so on) otherwise the module may be damaged. (d) if the module keeps displaying the same pattern for a long period of time, the image may be "sticked" to the screen. to avoid image sticking, it is recommended to use a screen saver. (e) this module has its circuitry pcb's on the rear side and should be handled carefully in order not to be stressed. (f) please contact sec in advance when you display the same pattern for a long time. www..net www..net
