13. LCD MODULES HANDLING PRECAUTIONS
Please remove the protection 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.
14. 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
