cpt chunghw a pictures tubes, ltd., cpt co nfidential 20/22 10.1 a ssemb ly precaution (1) please use the mounting hol e on the module side in installing and do not beading or wrenching lcd in assembling. and please do not drop, bend or twist lcd module in handling. (2) please design display housing in acco rdance with the following guidelines. ? housing case must be destined carefully so as not to put stresses on lcd all sides and not to wrench module. the stresses may cause non-uniformity even if there is no non-uniformity statically. ? keep sufficient clearance between lcd m odule back surface and housing when the lcd module is mounted. approximately 1.0 mm of the clearance in the design is recommended taking into account the to lerance of lcd module thickness and mounting structure height on the housing. ? when some parts, such as, fpc cable and ferrite plate, are installed underneath the lcd module, still sufficient clearance is required, such as 0.5mm. this clearance is, especially, to be reconsidered when the additional parts are implemented for emi countermeasure. ? design the inverter location and connector position carefully so as not to give stress to lamp cable, or not to interface the lcd module by the lamp cable. ? keep sufficient clearance between lcd module and the others parts, such as inverter and speaker so as not to interface the lcd module. approximately 1.0mm of the clearance in the design is recommended. (3) please do not push or scratch lcd panel surface with any-thing hard. and do not soil lcd panel surface by touching with bare hands . ( polarizer film, surface of lcd panel is easy to be flawed.) (4) please do not press any parts on the rear side such as source tcp, gate tcp, control circuit board and fpcs during handling lcd module. if pressing rear part is unavoidable, handle the lcd module with care not to damage them. (5) please wipe out lcd panel surface with absorb ent cotton or soft clothe in case of it being soiled. (6) please wipe out drops of adhesives like saliva and water on lcd panel surface immediately. they might damage to cause panel surface variation and color change. (7) please do not take a lcd module to pi eces and reconstruct it. resolving and reconstructing modules may cause them not to work well. (8) please do not touch metal frame s with bare hands and soiled gloves. a color change of the metal frames can happen during a long preservation of soiled lcd modules. (9) please pay attention to handling lead wire of backlight so that it is not tugged in connecting with inverter. 10.2 operating precautions (1) please be sure to turn off the power s upply before connecting a nd disconnecting signal input cable. (2) please do not change variable resistance settings in lcd module. they are adjusted to the most suitable value. if they are chan ged, it might happen lcd does not satisfy the characteristics specification. (3) please consider that lcd backlight takes longer time to become stable of radiation characteristics in low temperature than in room temperature. (4) a condensation might happen on the surface a nd inside of lcd module in case of sudden change of ambient temperature. (5) please pay attention to displaying the same pattern for very long time. image might stick on lcd. if then, time going on can make lcd work well. (6) please obey the same caution descriptions as ones that need to pay attention to ordinary electronic parts. www.yslcd.com.tw studio technology co.,ltd www.datasheet.net/ datasheet pdf - http://www..co.kr/
cpt chunghw a pictures tubes, ltd., cpt co nfidential 21/22 10.3 precauti ons w ith electrostatics (1) this lcd module use cmos-ic on circuit board and tft-lcd panel, and so it is easy to be affected by electrostatics. please be careful with electrostatics by the way of your body connecting to the ground and so on. (2) please remove protection film very slowly on the surface of lcd module to prevent from electrostatics occurrence. 10.4 storage precautions (1) when you store lcds for a long time, it is recommended to keep the temperature between 0 ~40 without the exposure of sunlight and to keep the humidity less than 90%rh. (2) please do not leave the lcds in the envir onment of high humidity and high temperature such as 60 90%rh. (3) please do not leave the lcds in the e nvironment of low temperature; below -20 . 10.5 safety precautions (1) when you waste lcds, it is recommended to crush damaged or unnecessary lcds into pieces and wash them off with solvents su ch as acetone and ethanol, which should later be burned. (2) if any liquid leaks out of a damaged-glass cell and comes in contact with the hands, wash off thoroughly with soap and water. 10.6 others (1) a strong incident light into lcd panel might cause display characteristics' changing inferior because of polarizer film, color f ilter, and other materi als becoming inferior. please do not expose lcd m odule direct sunlight land strong uv rays. (2) please pay attention to a panel side of lcd module not to contact w ith other materials in preserving it alone. (3) for the packaging box, please pa y attention to the followings: ? packaging box and inner case for lcd are designed to protect the lcds from the damage or scratching dur ing transportation. please do not open except picking lcds up from the box. ? please do not pile them up more than 3 boxes. (they are not designed so.) and please do not turn over. ? please handle packaging box with care not to give them sudden shock and vibrations. and also please do not throw them up. ? packing box and inner case for lcds are made of cardboard. so please pay attention not to get them wet. (such like keeping them in high humidity or wet place can occur getting them wet.) www.yslcd.com.tw studio technology co.,ltd www.datasheet.net/ datasheet pdf - http://www..co.kr/
