6.general precautions 6.1.safety liquid crystal is poisonous. do not put it in your mouth . if liquid crystal touches your skin or clothes, wash it off immediately by using soap and water. 6.2.handling 1. the lcd panel is plate glass. do not subject the pane l to mechanical shock or to excessive force on its surface. 2. the polarizer attached to the display is easily da maged. please handle it carefully to avoid scratch or other damages. 3. to avoid contamination on the display surface, do no t touch the module surface with bare hands. 4. keep a space so that the lcd panels do not touch o ther components. 5. put cover board such as acrylic board on the surface of lcd panel to protect panel from damages. 6. transparent electrodes may be disconnected if you use the lcd panel under environmental conditions where the condensation of de w occurs. 7. do not leave module in direct sunlight to avoid malfunction o f the ics. 6.3.static electricity 1. be sure to ground module before turning on power or operating module. 2. do not apply voltage which exceeds the absolute maxi mum rating value. 6.4.storage 1. store the module in a dark room where must keep at +2510 and 65%rh or less. 2. do not store the module in surroundings contai ning organic solvent or corrosive gas. 3. store the module in an anti-electrostatic container or bag. 6.5.cleaning 1. do not wipe the polarizer with dry cloth. it migh t cause scratch. 2. only use a soft sloth with ipa to wipe the polarize r, other chemicals might permanent damage to the polarizer. www..net
