9. HANDLING CAUTIONS
9.1 ESD (Electrical Static Discharge) Strategy ESD will cause serious damage of the panel, ESD strategy is very important in handling. Following items are the recommended ESD strategy (1) In handling LCD panel, please wear non-charged material gloves. Connect the wrist conduction ring to the earth and the conducting shoes to the earth are necessary. (2) The machine and working table for the panel should have ESD protection strategy. (3) In handling the panel, using ionized air to decrease the charge in the environment is necessary. (4) In the process of assembly the module, shield case should connect to the ground. 9.2 Environment (1) Working environment of the panel should be in the clean room. (2) The front polarizer is easy to be damaged. Handle it carefully and do not scratch it by sharp material. (3) Panel has polarizer protective film in the surface. Please remove the protection film of polarizer slowly with ionized air to prevent the electrostatic discharge. 9.3 Others (1) Turn off the power supply before connecting and disconnecting signal input cable. (2) The connection area of FPC and panel is very weak, do not handle panel only by FPC or bend FPC. (3) Water drop on the surface or condensation as panel power on will corrode panel electrode. (4) As the packing bag open, watch out the environment of the panel storage. High temperature and high humidity environment is prohibited. (5) When the TFT LCD module is broken, please watch out whether liquid crystal leaks out or not. If your hand touches liquid crystal, wash your hand cleanly by water and soap as soon as possible.
