12-2) Precautions in Mounting
Polarizer which is made of soft material and susceptible to flaw must be handled carefully.
Protective film (Laminator) is applied on the surface to protect it against scratches and
dirties. It is recommended to peel off the laminator immediately before the use, taking care
of static electricity.
Precautions in peeling off the laminator
A) Working Environment
When the laminator is peeled off, static electricity may cause dust to stick to the
polarizer surface. To avoid this, the following working environment is desirable.
a) Floor：Conductive treatment of 1MΩ or more on the tile
(conductive mat or conductive paint on the tile)
b) Clean room free form dust and with an adhesive mat on the doorway.
c) Advisable humidity：50%∼70% Advisable temperature：15℃∼27℃
d) Workers shall wear conductive shoes, conductive work clothes, conductive gloves and
an earth band.
B) Working Procedures
a) Direct the wind of discharging blower somewhat downward to ensure that module is
blown sufficiently. Keep the distance between module and discharging blower within
20 cm.
b) Attach adhesive tape to the laminator part near discharging blower so as to protect
polarizer against flaw.
c) Peel off laminator, pulling adhesive tape slowly to your side taking 5 or more second.
d) On peeling off the laminator, pass the module to the next work process to prevent the
module to get dust.
e) Method of removing dust from polarizer
･ Blow off dust with N
2
blower for which static electricity preventive measure has been
taken.
･ Since polarizer is vulnerable, wiping should be avoided.

C) 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.
D) 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.
