14. 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 dam aged and the liquid crysta l substance inside it leak s out, do not get any in
your mouth. If the substance com e into contact with your skin or clothes prom ptly wash it of f 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 elem ents by static electric ity, be caref ul to m aintain 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 am ount of static electricity gene rated, 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 st atic electricity char ging under low te mperature /
normal humidity conditions (avoi d high tem perature / high hum idity a nd low temperatu res be low
0°C).Whenever possible, the LCD modules should be stored in the same conditions in which they were
shipped from our company.
.15. 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 im ages 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 m inimize the perform ance degradation of th e 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
