(b) because the inverter us e high voltage, it should be disconnected from power before it is assembled or disassembled. (c) refrain from strong mechanical shock and / or any force to the module. in addition to damage, this may cause im proper operation or damage to the module and ccft back light. (d) note that polarizers are very fragile and coul d be damage easily. do not press or scratch the surf ace harder than a hb pencil lead. (e) wipe off water droplets or oil immedi ately. 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 absorbe nt cotton or soft cloth. (g) desirable cleaners are water, ipa(isopropy l alcohol) or hexane. do not use ketone type materi als(ex. acetone), ethyl alco hol, toluene, ethyl acid or methyl chloride. it might permanent damage to the polarizer due to chemical reaction. (h) if the liquid crystal material leaks fr om the panel, it should be kept away from the eyes or mouth . in case of cont act with hands, legs or clothes, it must be washed away with soap thoroughly. (i) protect the module from static, or the cmos gate array ic would be damaged. (j) use finger-stalls with soft gloves in order to keep displa y clean during the incoming inspection and assembly process. (k) do not disassemble the module. (l) do not pull or fold the lamp wire. (m) do not adjust the variable resistor located on the module. (n) protection film for polarizer on the module should be slowly peeled off just before use so that the electrostati c charge can be minimized. (o) pins of i/f connector should not be touched directly with bare hands. www..net www..net
1bhf ( %pd/p -5*"" .0%&- 10.2 storage (a) do not leave the module in high temper ature, and high humidity for a long time. it is highly recommended to store the module with temperature from 0 to 35 ? and relative humidity of less than 70%. (b) do not store the tft-lcd module in direct sunlight. (c) the module should be stored in a dark plac e. it is prohibited to apply sunlight or fluorescent light in storing. 10.3 operation (a) do not connect or disconnect t he 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 frequ ency circuits. sufficient suppr ession to the electromagnetic interference should be done by system manufacturers. grounding and shielding meth ods may be important to mi nimize the interference. (d) the cable between the back light connector and its inverter power supply should be connected directly with a minimi zed length. a longer cable between the back light and the inverter may ca use lower luminance of lamp(ccft) and may require higher startup voltage(vs). 10.4 operation condition guide (a) the lcd product should be oper ated under norm al conditions. normal condition is defined as below; - temperature : 20 ? 15 ? - humidity : 55 ? 20% - display pattern : continually ch anging pattern (not stationary) (b) if the product will be used in extreme conditions such as high temperature, humidity, display patterns or operation time etc.., it is strongly recommended to contact sec for application engineerin g advice. otherwise, its reliability and function may not be guarant eed. extreme conditions are commonly found at airports, transit stations, banks, stock market, and controlling systems. www..net www..net
1bhf ( %pd/p -5*"" .0%&- 10.5 others (a) ultra-violet ray filter is necessary for outdoor operation. (b) module should be turned clockwise (regular front view perspective) when used in portrait mode (c) avoid condensation of water. it may result in improper operat ion or disconnection of electrode. (d) do not exceed the absolute maximum ra ting value. ( supply voltage variation, input voltage variation, variation in part contents and envir onmental temperature, and so on) otherwise the module may be damaged. (e) if the module keeps displaying the sa me 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. (f) this module has its circuitry pcb's on the rear side and should be handled carefully in order not to be stressed. (g) please contact sec in advance when you display the sa me pattern for a long time. www..net www..net
