ld-20z53b13 10. handling precautions a) be sure to turn off the power supply when inserting or disconnecting the cable. b)our tft-lcd module is designed to be fixed to the hardware with mounting holes on 4-corners on the backside. be sure to design the cabinet so that the module can be in stalled without any extra stress such as warp or twist. c) wipe off water drop immediately. long contact with water may cause discoloration or spots. d) when the panel surface is soiled, wipe it with absorbent cotton or other soft cloth. e) since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. handle with care. f) since cmos lsi is used in this module, take care of static electricity and ensure the human earth when handling. observe all other precautionary requirements in handling components. g) since there is a circuit board in the module b ack, stress shall not be impressed in designing and assembling. if stress is impressed, there ari ses a possibility that circuit parts may be damaged. h) direct sunlight on lcd panel may cause degrad ation of panel quality. do not expose the lcd panel to direct sunlight. lightproof shade etc. s hould be attached when lcd panel is used under such environment. i) connect gnd to 4 place of mounting holes to get stable against emi and external noise. j) when handling lcd modules and assembling th em into cabinets, please be noted that long-term storage in the environment of oxidization or deoxidization gas and the use of such materials as reagent, solvent, adhesive, resin, etc. wh ich generate these gasses, may cause corrosion and discoloration of the lcd modules. k) when installing lcd modules in the cabin et, we recommend to tighten screws with ?torque=0.25 0.30n ? m?. be sure to confirm it in the same condition as it is built in your instrument. inserting length to the module shall be within 5mm. tapping screws shall be tighten only one time. more than two time tightening is not assured. please take care in the case of reworking. l) liquid crystal contained in the panel may leak if the lcd is broken. rinse it as soon as possible if it gets inside your eye or mouth by mistake. m) notice: never dismantle the module , because it will cause failure. please don't remove the fixed tape, insulating tape etc that was pasted on the original module. (except for protection film of the panel and the cr epe tape(yellow tape) temporarily adhered on the module.) n) be careful when using it for long time with fixed pattern display as it may cause afterimage. please use a screen saver etc., in order to avoid an afterimage. o) adjusting volume have been set optimally before shipment, so do not change any adjusted value. if adjusted value is changed, the specification may not be satisfied. p) if a minute particle get into the module and adheres on an optical material, it may cause display irregularity issue, etc. therefore, fine-pitch filters have to be built into cooling and inhalation hole if you intend to install a fan. q) liquid crystal can be damaged by ultraviolet light . be sure not to operate or storage under direct sunlight or strong ultraviolet light for a long time. r) please storage modules in ambient temperature if possible. below the storage temperature, liquid crystal can freeze and damage the lcd paenel. above st orage temperature, it can irreversibly turn into isotropic state which cannot work as display.
