5.3 power on/off sequence to prevent a latch-up or dc operation of the lcd module, the power on/off sequence should be as the diagram below. 0LTA320AB02 doc. no 06-000-g- 071220 page 19/26 t1 : v dd rising time from 10% to 90% t2 : the time from v dd to valid data at power on. t3 : the time from valid data off to v dd off at power off. t4 : v dd off time for windows restart t5 : the time from valid data to b/l enable at power on. t6 : the time from valid data off to b/l disable at power off. the supply voltage of the external system for the module input should be the same as the definition of v dd . apply the lamp voltage within the lcd operation range. when the back light turns on before the lcd operation or the lcd turns off before the back light turns off, the display may momentarily show abnormal screen. in case of v dd = off level, please keep the level of input signals low or keep a high impedance. t4 should be measured after the module has been fully discharged between power off and on period. interface signal should not be kept at high impedance when the power is on.

9. general precautions 9.1 handling (a) when the module is assembled, it should be attached to the system firmly using all mounting holes. be careful not to twist and bend the module. (b) because the inverter use high voltag e, 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 improper operation or damage to the module and ccfl back light. (d) note that polarizers are very fragile and could be damage easily. do not press or scratch the surface harder than a hb 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 alcohol) or hexane. do not use ketone type materials(ex. acetone), ethyl alcohol, toluene, ethyl acid or methyl chloride. it might permanent damage to the polarizer due to chemical reaction. model LTA320AB02 doc. no 06-000-g- 071220 page 24/26 (h) 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, 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 & lvds board. (m) do not connect n.c pins. (samsung internal use only) (n) protection film for polarizer on the module should be slowly peeled off just before use so that the electrostatic charge can be minimized. must put on antistatic glove while handle a module (o) pins of i/f connector should not be touched directly with bare hands. www..net www..net
9.2 storage (a) do not leave the module in high temperature, and high humidity for a long time. it is highly recomm ended to st ore the module with tem perature 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 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 model LTA320AB02 doc. no 06-000-g- 071220 page 25/26 (d) the cable between the back light connector and its inverter power supply should be connected directly with a minimized length. a longer cable between the back light and the inverter may cause lower luminance of lamp(ccfl) and may require higher startup voltage(vs). 9.4 operation condition guide (a) the lcd product should be oper ated under normal conditions. normal condition is defined as below; - temperature : 20 15 - humidity : 55 20% - display pattern : continually changing pattern (not stationary) (b) if the product will be used in extreme conditions such as high temperature, humidity, display patterns or operation ti me etc.., it is strongly recommended to contact sec for application engineer ing advice. otherwise, its reliability and function may not be guaranteed. extreme conditions are commonly found at airports, transit stati ons, banks, stock market, and controlling systems. www..net www..net
9.5 others (a) ultra-violet ray filter is necessary for outdoor operation. (b) avoid condensation of water. it may result in improper operation or disconnection of electrode. (c) do not exceed the absolute maximum rati ng 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. model LTA320AB02 doc. no 06-000-g- 071220 page 26/26 www..net www..net
