preliminary 9. general precautions 9-1. handling assembled, lcd module should be firmly attached to the set. do not bent or twist. refrain from strong mechanical shock and forces to the module. it may cause improper operating or damage to the module. do not touch, press or rub the display panel with hard or stiff tools or subjects. the polarizer is easily damaged. wipe off water or oil drop immediately if you leave drop for a long time, stain and discoloration may occur. when cleaning the surface of polarizer, use so ft cloth with solvent like isopropyl or ethyl alchol or hexane. do not use water, ketone, acetone, ethyl al chol, toluene, ethyl acid, methyl chloride. be care full of applying hcfc, chlorine(cl) , salfur(s), spittle, fingerprint to ito pattern these may cause ito corrosion. when handling the lcd module, put on a soft glover like finger-glover. protection film on the polarizer shall be slowly peeled off just before use, so that the electrostatic charge can be minimized. do not touch pads or pins of interface directly with bare hands. protect the module from static electricity, it may cause damage to cmos lsi. if the liquid crystal leaks from the panel it should be kept away from the eyes and mouths. in case of contact with skins, wash away thoroughly with soap and water. 9-2. operation do not input any signals before power is turned on. do not connect or disconnect the module on the state of power-on. power supply should be turned on or off according to power on/off sequence. supply voltage within the specified voltage li mit, the maximum rating, higher voltage cause the shorter lcd life or damaged. avoid condensation of water, it may cause improper operation or disconnection of electrode. do not leave lcd module in direct sunlight and strong ultraviolet ray for many hours. at that time the liquid crystal sh all be deteriorated by ultraviolet. 9-3. storage do not leave the module in high temperature and humidity for a long time. it is recommended to store the module in the place with temperature from 0 to 35 and relative humidity of less than 70%. do not store the lcd module in the direct sunlight. store the module in a dark place without sunlight and fluorescent. avoid intensive shock and falls from a height. model no. : vg-17h29-b voda tech doc no. : vg-17h29-b page : 13/15 free datasheet http:///
