10.1 Handling Precautions
10.1.1 The display panel is made of glass. Do not subject it to a mechanical
shock by dropping it from a high place, etc.
10.1.2 If the display panel is damaged and the liquid crystal substance inside it
leaks out, be sure not to get any in your mouth, if the substance comes
into contact with your skin or clothes, promptly wash it off using soap
and water.
10.1.3 Do not apply excessive force to the display surface or the adjoining areas
since this may cause the color tone to vary.
10.1.4 The polarizer covering the display surface of the LCD module is soft and
easily scratched. Handle this polarizer carefully.
10.1.5 If the display surface is contaminated, breathe on the surface and gently
wipe it with a soft dry cloth. If still not completely clear, moisten cloth
with one of the following solvents:
Isopropyl alcohol
Ethyl alcohol
Solvents other than those mentioned above may damage the polarizer.
Especially, do not use the following:
Water
Ketone
Aromatic solvents
10.1.6 Do not attempt to disassemble the LCD Module.
10.1.7 If the logic circuit power is off, do not apply the input signals.
10.1.8 To prevent destruction of the elements by static electricity, be careful to
maintain an optimum work environment.
a. Be sure to ground the body when handling the LCD Modules.
b. Tools required for assembly, such as soldering irons, must be properly
ground.
c. To reduce the amount of static electricity generated, do not conduct
assembly and other work under dry conditions.
d. The LCD Module is coated with a film to protect the display surface.
Be care when peeling off this protective film since static electricity may
be generated.
10.2 Storage precautions
10.2.1 When storing the LCD modules, avoid exposure to direct sunlight or to
the light of fluorescent lamps.
10.2.2 The LCD modules should be stored under the storage temperature range.
If the LCD modules will be stored for a long time, the recommend
condition is:
Temperature : 0 40
Relatively humidity: 80%
10.2.3 The LCD modules should be stored in the room without acid, alkali and
harmful gas.
10.3 The LCD modules should be no falling and violent shocking during
transportation, and also should avoid excessive press, water, damp and
sunshine.
