(2) apply the led voltage within the lcd operation range. when the back-light turns on before the lcd operation or the lcd tu rns off before the leds turns off, the display may momentarily become white. (3) in case of vdd = off level, please keep the level of input signals on the low or keep a high impedance. (4) t8 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.

(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 and led back-light. (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 t he droplets for a long time, staining and discoloration may occur. (e) if the surface of the polarizer is dirty, clean it using some absorb ent cotton or soft cloth. (f) the desirable cleaners are wate r, ipa(isopropyl alcohol) or hexane. do not use ketone type materials(ex. acetone), ethyl alcohol, toluene, ethyl acid or methyl chloride. it might perma nent 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 cmos ic. (i) use finger-stalls with soft gloves in orde r to keep display clean during the incoming inspection and assembly process. (j) do not disasse mble the module. (k) do not adjust the variable resi stor which is located on the back side. (l) protection film for polarizer on the modul e shall be slowly peele d off just before use so that the electrostatic charge can be minimized. (m) pins of i/f connector shall not be touched directly with bare hands.
doc.no. rev.no page LTG430WQ-F02 / 28 28 05-002-g-050630 preliminary 11.2 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 te mperature from 0 to 35 cand 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. 11.3 operation (a) do not connect,disconnect t he module in the ? power on? condition. (b) power supply should always be tu rned on/off by following item 6.5 ? power on/off sequence ?. (c) module has high frequenc y circuits. sufficient suppression to the electromagnetic interference shall be done by system manufa cturers. grounding and shielding methods may be important to minimize the interference. 11.4 others (a) ultra-violet ray filter is necessary for outdoor operation. (b) avoid condensation of water. it may result in improper operat ion or disconnection of electrode. (c) do not exceed the absolute maximum rating va lue. ( the supply volt age variation, input voltage variation, variation in part contents an d environmental temp erature, so on) otherwise the module may be damaged. (d) if the module displays the sa me 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 fpc?s on the rear side and should be handled carefully in order not to be stressed.
