(1) the supply voltage of the external system for the module input should be the same as the definition of v dd . ( 2) 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 become white. (3) in case of v dd = off level, please keep the level of input signals on the low or keep a high impedance. (4) t4 should be measured after the module has been fully discharged between power off and on period. (5) interface signal shall not be kept at high impedance when the power is on. power supply v dd 0.9 v dd 0.9 v dd 0v 0 v valid signals t 3 0.5 < << < t 1 10 msec 0 < << < t 2 50 msec 0 < << < t 3 50 msec 500 msec t 4 t 1 t 2 t 4 0.1 v dd 0.1 v dd power on/off sequence back-light 200 msec t 5 200 msec t 6 power on power off t 5 t 6 5 0% 50% t1 : vdd rising time from 10% to 90% t2 : the time from vdd to valid data at power on. t3 : the time from valid data off to vdd off at power off. t4 : vdd 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. ??? ?? ??? ???? ??? http://www.notebook-lcd.ru ??? , ????? , .75, ?.2 ? .: +79015534828 www.datasheet.co.kr datasheet pdf - http://www..net/

doc.no. rev.no page / 30 LTN156AT02-D 26 04-a01-s-081205 approval samsung secret 10. general precautions 1. handling (a) when the module is assembled, it should be attached to the system firmly using every mounting holes. be careful not to twist and bend the modules. (b) 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. (c) note that polarizers are very fragile and could be easily damaged. do not press or scratch the surface harder than a hb pencil lead. (d) wipe off water droplets or oil immediately. if you leave the droplets for a long time, staining and discoloration may occur. (e) if the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth. (f) the desirable cleaners are water, ipa (isoprophyl 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. (g) 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 thoroughly with soap. (h) protect the module from static , it may cause damage to the c-mos gate array ic. (i) use fingerstalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (j) do not disassemble the module. (k) do not pull or fold the lamp wire. (l) do not adjust the variable resistor which is located on the back side. (m) protection film for polarizer on the module shall be slowly peeled off just before use so that the electrostatic charge can be minimized. (n) pins of i/f connector shall not be touched directly with bare hands. ??? ?? ??? ???? ??? http://www.notebook-lcd.ru ??? , ????? , .75, ?.2 ? .: +79015534828 www.datasheet.co.kr datasheet pdf - http://www..net/
doc.no. rev.no page / 30 LTN156AT02-D 27 04-a01-s-081205 approval samsung secret 2. storage ( a) do not leave the module in high temperature, and high humidity for a long time. it is highly recommended to store the module with temperature from 0 to 35 c and relative humidity of less than 70%. (b) do not store the tft-lcd module in direct sunlight. (c) the module shall be stored in a dark place. it is prohibited to apply sunlight or fluorescent light during the store. 3. operation (a) do not connect,disconnect the module in the power on condition. (b) power supply should always be turned on/off by following item 6.3 power on/off sequence . (c) module has high frequency circuits. sufficient suppression to the electromagnetic interference shall be done by system manufacturers. grounding and shielding methods may be important to minimize the interference. (d) the standard limited warranty is only applicable when the module is used for general notebook applications. if used for purposes other than as specified, sec is not to be held reliable for the defective operations. it is strongly recommended to contact sec to find out fitness for a particular purpose. 4. 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 rating value. ( the supply voltage variation, input voltage variation, variation in part contents and environmental temperature, so on) otherwise the module may be damaged. (d) if the module displays the same pattern continuously for a long period of time,it can be the situation when the image sticks to the screen. (e) this module has its circuitry pcbs on the rear side and should be handled carefully in order not to be stressed. ??? ?? ??? ???? ??? http://www.notebook-lcd.ru ??? , ????? , .75, ?.2 ? .: +79015534828 www.datasheet.co.kr datasheet pdf - http://www..net/
