11-4 Cautions in assembly / Handling pre cautions.
As the polarizer can be easily scratched, be most careful in handling it.
① Work environments in assembly.
Working under the following environments is desirable:
a) Implement more than 1MΩ conductive treatment (by placing a conductive mat or applying
Conductive paint) on the floor or tiles.
b) No dusts come in to the working room. Place an adhesive, anti-dust mat at the entrance of the room.
c) Humidity of 50～70% and temperature of 15～27°C are desirable.
d) All workers wear conductive shoes, conductive clothes, conductive fingerstalls and grounding
belts without fail.
e) Use a blower for electrostatic removal. Set it in a direction slightly tilt downward so that each
Module can be well subjected to its wind. Set the blower at an optimum distance between the
blower and the module.
② How the remove dust on the polarizer
a) Blow out dust by the use of an N2 blower with antistatic measures taken. Use of an ionized air
Gun is recommendable.
b) When the panel surface is soiled, wipe it with soft cloth.
③ In the case of the module’s metal part (shield case) is stained, wipe it with a piece of dry, soft
cloth. If rather difficult, give a breath on the metal part to clean better.
④ If water dropped, etc. remains stuck on the polarizer for a long time, it is apt to get discolored or
cause stains. Wipe it immediately.
⑤ As a glass substrate is used for the TFT-LCD panel, if it is dropped on the floor or hit by
something hard, it may be broken or chipped off.
⑥ Since CMOS LSI is used in this module, take care of static electricity and take the human earth into
consideration when handling.
