Notes on Handling

(1) Static charge prevention

Be sure to take the following protective measures. TFT-LCD panels are easily damaged by static charges.

a) Use non-chargeable gloves, or simply use bare hands.

b) Use an earth-band when handling.

c) Do not touch any electrodes of a panel.

d) Wear non-chargeable clothes and conductive shoes.

e) Install conductive mats on the working floor and working table.

f) Keep panels away from any charged materials.

g) Use ionized air to discharge the panels.

(2) Protection from dust and dirt

a) Operate in a clean environment.

b) When delivered, the panel surface (glass panel) is covered by a protective sheet. Peel off the protective

sheet carefully so as not to damage the glass panel.

c) Do not touch the glass panel surface. The surface is easily scratched. When cleaning, use a clean-

room wiper with isopropyl alcohol. Be careful not to leave a stain on the surface.

d) Use ionized air to blow dust off the glass panel.

(3) Light resistance

Orientation film and organic matter such as liquid crystal used inside of the LCD panel deteriorate by the

light chemical reaction. As a result, its indication characteristic may irreversible change. The progress of its

chemical reaction is influenced by short wavelength side's light (characteristics of UV cut filter) and

temperature when quantitiy of light is constant. To control its progress, attach suitable UV cut filter between

light source and LCD panel. (Sharp characteristic's filter of

λ > 425nm is recommended.) Also, use suitable

IR cut filter to lower the temperature of LCD panel and cool the panel carefully.

(4) Other handling precautions

a) Do not twist or bend the flexible PC board especially at the connecting region because the board is

easily deformed.

b) Do not drop the panel.

c) Do not twist or bend the panel or panel frame.

d) Keep the panel away from heat sources.

e) Do not dampen the panel with water or other solvents.

f) Avoid storing or using the panel at a high temperature or high humidity, which may result in panel

damages.

g) Minimum radius of bending curvature for a flexible substrate must be 1mm.

h) Torque required to tighten screws on a panel must be 0.098N · m (measurement screw : JCIS Type 1,

M1.7 flat head screw) or less.

i) Do not pressure the portion other than mounting hole (cover).
