cpt chunghwa pictures tubes, ltd., cpt confidential 23/24 CLAA156WA12-scl-v1-20111117 10. handling precautions for tft-lcd module please pay attention to the followings in handling- tft-lcd products. 10.1 assembly precaution (1) please use the mounting hole 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 accordance wit h 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-unifo rmity even if there is no non-uniformity statically. keep sufficient clearance between lcd module back surface and housing when the lcd module is mounted. approximately 1.0 mm of the cle arance in the design is recommended taking into account the tolerance of lc d module thickness and mounting structure height on the housing. when some parts, such as, fpc cable and ferrite pl ate, are installed underneath the lcd module, still sufficient clearance is required, suc h as 0.5mm. this clearance is, especially, to be reconsidered when the additional parts are im plemented for emi countermeasure. keep sufficient clearance between lcd module and t he others parts, such as speaker so as not to interface the lcd module. approximately 1.0 mm 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. (polariz er 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 pres sing rear part is unavoidable, handle the lcd module with care not to damage them. (5) please wipe out lcd panel surface with absorben t 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 pieces and r econstruct it. resolving and reconstructing modules may cause them not to work well. (8) please do not touch metal frames with bare hand s and soiled gloves. a color change of the metal frames can happen during a long preservation of soiled lcd modules. 10.2 operating precautions (1) please be sure to turn off the power supply bef ore connecting and disconnecting signal input cable. (2) please do not change variable resistance settin gs in lcd module. they are adjusted to the most suitable value. if they are changed, it might happen lcd does not satisfy the characteristics specification. (3) please consider that lcd backlight takes longer time to become stable of radiation
cpt chunghwa pictures tubes, ltd., cpt confidential 24/24 CLAA156WA12-scl-v1-20111117 characteristics in low temperature than in room tem perature. (4) a condensation might happen on the surface and inside of lcd module in case of sudden change of ambient temperature. (5) please pay attention to displaying the same pat tern 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 on es that need to pay attention to ordinary electronic parts. 10.3 precautions with electrostatics (1) this lcd module use cmos-ic on circuit board an d 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 th e surface of lcd module to prevent from electrostatics occurrence. 10.4 storage precautions (1) when you store lcds for a long time, it is reco mmended to keep the temperature between 0 ~40 without the exposure of sunlight and to keep the h umidity less than 90%rh. (2) please do not leave the lcds in the environment of high humidity and high temperature such as 60 90%rh. (3) please do not leave the lcds in the environment 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 such 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 throughly with soap and water. 10.6 others (1) a strong incident light into lcd panel might ca use display characteristics' changing inferior because of polarizer film, color filter, and other materials becoming inferior. please do not expose lcd module direct sunlight land strong uv ra ys. (2) please pay attention to a panel side of lcd mod ule not to contact with other materials in preserving it alone. (3) for the packaging box, please pay attention to the followings: packaging box and inner case for lcd are designed to protect the lcds from the damage or scratching during transportation. please do not op en except picking lcds up from the box. please do not pile them up more than 3 boxes. (the y 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 car dboard. so please pay attention not to get them wet. (such like keeping them in high humidity or we t place can occur getting them wet.)
