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. Fol-
lowing items are the recommend ESD strategy
(1) In handling LCD panel, please wear non-charged material gloves. And the conduction
ring connect wrist to the earth and the conducting shoes to the earth is necessary.
(2) The machine and working table for the panel should have ESD prohibition strategy.
(3) In handling the panel, ionize flowing decrease the charge in the environment is neces-
sary.
(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 in the clean room.
(2) The front polarizer is easy 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 elec-
trode.
(4) As the packing bag open, watch out the environment of the panel storage. High tem-
perature 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
