10. PRECAUTIONS FOR USING LCD MODULE
10.1 HANDING PRECAUTIONS
(1) The display panel is made of glass. Do not subject it to a mechanical shock or impact by dropping it.
(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 a 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
- Ketone
- Aromatic solvents
(7) Extra care to minimize corrosion of the electrode. Water droplets, moisture condensation or a current flow in a
high-humidity environment accelerates corrosion of the electrode.
(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 I/O 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 he LCD Module.
- 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.

10.2 STORAGE PRECAUTIONS
When storing The LCD Module, avoid exposure to direct sunlight of fluorescent lamps. Keep the modules in bags
(avoid high temperature/ high humidity and low temperatures below 0℃). Whenever possible, the LCD Module should
be stored in the same conditions in which they were shipped from our company.
10.3 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 Module 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 recovered 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 Module 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.
11. USING LCD MODULES
11.1 LIQUID CRYSTAL DISPLAY MODULES
LCD is composed of glass and polarizer. Pay attention to the following items when handling.
(1) Please keep the temperature within specified range for use and storage. Polarization degradation, bubble generation
or polarizer peel-off may occur with high temperature and high humidity.
(2) Do not touch, push or rub the exposed polarizers with anything harder than a HB pencil lead (glass, tweezers, etc).
(3) N-hexane is recommended for cleaning the adhesives used to attach front/rear polarizers and reflectors made of
organic substances, which will be damaged by chemicals such as acetone, toluene, toluene, ethanol and isopropyl
alcohol.
(4) When the display surface becomes dusty, wipe gently with absorbent cotton or other soft material like chamois
soaked in petroleum ether. Do not scrub hard to avoid damaging the display surface.
(5) Wipe off saliva or water drops immediately, contact with water over a long period of time may cause deformation or
color fading.
(6) Avoid contacting oil and fats.
- 22 -
(7) Condensation on the surface and contact with terminals due to cold will damage, stain or polarizers. After products
are tested at low temperature they must be warmed up in a container before coming is contacting with room
temperature air.
(8) Do not put or attach anything on the display area to avoid leaving marks on.
(9) Do not touch the display with bare hands. This will stain the display area and degrade insulation between terminals
(some cosmetics are determinate to the polarizers).
(10)As glass is fragile, it tends to become or chipped during handling especially on the edges. Please avoid dropping or
jarring.
11.2 INSTALLING LCD MODULE
Attend to the following items when installing the LCM.
(1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
(2) When assembling the LCM into other equipment, the spacer to the bit between the LCM and the fitting plate should
have enough height to avoid causing stress to the module surface, refer to the individual specifications for
measurements. The measurement tolerance should be ±0.1mm.
11.3 ELECTRO-STATIC DISCHARGE CONTROL
Since this module uses a CMOS LSI, the same careful attention should be paid for electrostatic discharge
as for an ordinary CMOS IC.
(1) Make certain that you are grounded when handing LCM.
(2) Before removing LCM from its packing case or incorporating it into a set, be sure the module and your body have
the same electric potential.
(3) When soldering the terminal of LCM, make certain the AC power source for the soldering iron does not leak.
(4) When using an electric screwdriver to attach LCM, the screwdriver should be of ground potentiality to minimize as
much as possible any transmission of electromagnetic waves produced sparks coming from the commutator of the
motor.
(5) As far as possible, make the electric potential of your work clothes and that of the workbenches to the ground
potential.
(6) To reduce the generation of static electricity , be careful that the air in the work is not too dried. A relative humidity
of 50%-60% is recommended.

11.4 PRECAUTION FOR SOLDERING TO THE LCM
(1) Observe the following when soldering lead wire, connector cable and etc. to the LCM.
-Soldering iron temperature: 280 ±10°C.
-Soldering time: 3-4 sec.
-Solder: eutectic solder.
If soldering flux is used, be sure to remove any remaining flux after finishing to soldering operation. (This
does not apply in the case of a non-halogen type of flux.) It is recommended that you protect the LCD surface with a
cover during soldering the prevent any damage due to flux spatters.
(2) When soldering the electroluminescent panel and PC board, the panel and board should not be detached more than
three times. This maximum number is determined by the temperature and time conditions mentioned above, though
there may be some variance depending on the temperature of the soldering iron.
(3) When removing the electroluminescent panel from the PC board, be sure the solder has completely melted, otherwise
the soldered pad on the PC board could be damaged.
11.5 PRECAUTIONS FOR OPERATION
(1) Viewing angle varies with the change of liquid crystal driving voltage (Vo). Adjust Vo to show the best contrast.
(2) Driving the LCD in the voltage above the limit will shorten its lifetime.
(3) Response time is greatly delayed at temperature below the operating temperature range. However, this does not
mean the LCD will be out of the order. It will recover when it returns to the specified temperature range.
(4) If the display area is pushed hard during operation, the display will become abnormal. However, it will return to
normal if it is turned off and then on.
(5) Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit. Therefore, it must
be used under the relative condition of 40°C, 50% RH.
(6) When turning the power on, input each signal after the positive/negative voltage becomes stable.
11.6 STORAGE
When storing LCDS as spares for some years, the following precaution are necessary.
(1) Store them in a sealed polyethylene bag. If properly sca
