9. PRECAUTIONS FOR USING LCD MODULES
Handing Precautions
(1) The display panel is made of glass. Do not subject it to a mechanical shock by dropping it
or impact.
(2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to
get any in your mouth. If the substance contacts your skin or clothes, wash it off using soap and
water.
(3) Do not apply excessive force to the display surface or the adjoining areas since this may
cause the color tone to vary.
(4) The polarizer covering the display surface of the LCD module is soft and easily scratched.
Handle this polarizer carefully.
(5) If the display surface becomes contaminated, breathe on the surface and gently wipe it
with a soft dry cloth. If it is heavily contaminated, moisten cloth with one of the following
solvents :
- Isopropyl alcohol
- Ethyl alcohol
(6) Solvents other than those above-mentioned may damage the polarizer. Especially, do not
use the following.
- Water
Version 1.0
- Ketone
- Aromatic solvents
(7) Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is
accelerated by water droplets, moisture condensation or a current flow in a high-humidity
environment.
(8) Install the LCD Module by using the mounting holes. When mounting the LCD module
make sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend
the IO cable or the backlight cable.
(9) Do not attempt to disassemble or process the LCD module.
(10) NC terminal should be open. Do not connect anything.
(11) If the logic circuit power is off, do not apply the input signals.
(12) 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 modules.
- Tools required for assembling, such as soldering irons, must be properly grounded.
- To reduce the amount of static electricity generated, do not conduct assembling 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 (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.
Others
Liquid crystals solidify under low temperature (below the storage temperature range) leading
to defective orientation or the generation of air bubbles (black or white). Air bubbles may also be
generated if the module is subject to a low temperature.
If the LCD modules have been operating for a long time showing the same display patterns,
the display patterns may remain on the screen as ghost images and a slight contrast irregularity
may also appear. A normal operating status can be regained by suspending use for some time. It
should be noted that this phenomenon does not adversely affect performance reliability.
To minimize the performance degradation of the LCD modules resulting from destruction
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.
