11. LCD MODULES HANDLING PRECAUTIONS
 Please remove the protective foil of polarizer before using.
 The display panel is made of glass. Do not subject it to a mechanical shock by dropping it from a high
place, etc.
 If the display panel is damaged and the liquid crystal substance inside it leaks out, do not get any in
your mouth. If the substance come into contact with your skin or clothes promptly wash it off using
soap and water.
 Do not apply excessive force to the display surface or the adjoining areas since this may cause the color
tone to vary.
 The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this
polarize carefully.
 To prevent destruction of the elements by static electricity, be careful to maintain an optimum work
environment.
-Be sure to ground the body when handling the LCD module.
-Tools required for assembly, such as soldering irons, must be properly grounded.
-To reduce the amount of static electricity generated, do not conduct assembly and other work under
dry conditions.
-The LCD module is coated with a film to protect the display surface. Exercise care when peeling off
this protective film since static electricity may be generated.
 Storage precautions
When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps.
Keep the modules in bags designed to prevent static electricity charging under low temperature /
normal humidity conditions (avoid high temperature / high humidity and low temperatures below 0°C).
Whenever possible, the LCD modules should be stored in the same conditions in which they were
shipped from our company.
12. OTHERS
 Liquid crystals solidify at low temperature (below the storage temperature range) leading to defective
orientation of liquid crystal or the generation of air bubbles (black or white). Air bubbles may also be
generated if the module is subjected to a strong shock at a low temperature.
 If the LCD modules have been operating for a long time showing the same display patterns may remain
on the screen as ghost images and a slight contrast irregularity may also appear. Abnormal operating
status can be resumed to be normal condition by suspending use for some time. It should be noted that
this phenomena does not adversely affect performance reliability.
 To minimize the performance degradation of the LCD modules resulting from caused by static
electricity, etc. exercise care to avoid holding the following sections when handling the modules:
- Exposed area of the printed circuit board
- Terminal electrode sections
