impact by dropping it.
(2) If the display panel is damaged and the liquid crystal substance leaks out, besure 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 andgently wipe it with a soft dry cloth. If it is heavily contaminated, moisten a clothwith 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-The LCD Module is coated with - Aromatic solvents(7) Extra care to minimize corrosion of the electrode. Water droplets, moisturecondensation or a current flow in a high-humidity environment acceleratescorrosion 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, donot 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 tomaintain 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 properlygrounded.
-To reduce the amount of static electricity generated, do not conduct-- 17 --

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 begenerated.

11.2 Precaution For Soldering To The LCM
Observe the following when soldering lead wire, connector cable and etc. tothe 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 tosoldering 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.
When soldering the electroluminescent panel and PC board, the panel andboard should not be detached more than three times. This maximum number isdetermined by the temperature and time conditions mentioned above, though
there may be some variance depending on the temperature of the soldering iron.
When removing the electroluminescent panel from the PC board, be sure thesolder has completely melted, otherwise the soldered pad on the PC board could
be damaged.

11.3 Precaution 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 theorder. 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 of40°C, 50% RH.
(6) When turning the power on, input each signal after the positive/negative
voltage becomes stable.

11.4 Precaution For Storage
When storing LCDS as spares for some years, the following precaution arenecessary.
Store them in a sealed polyethylene bag. If properly scaled, there is no need for
desiccant.
Store them in a dark place. Do not expose to sunlight or fluorescent light, keep
the temperature between 0°C and 35°C.
The polarizer surface should not come in contact with any other objects. (Weadvise you to store them in the container in which they were shipped.)
Environmental conditions:-Do not leave them for more than 168hrs. at 60 °C.
-Should not be left for more than 48hrs. at –20 °C.

11.5 Safety
It is recommended to crush damaged or unnecessary LCDs into pieces andwash them off with solvents such as acetone and ethanol, which should later beburned.
If any liquid leaks out of a damaged glass cell and comes in contact with thehands, wash off thoroughly with soap and water.

11.6 Limited Warranty
Unless agreed between Matrix and customer, Matrix will replace or repair anyof its LCD and modules which are found to be functionally defective wheninspected in accordance with Matrix LCD acceptance standards (copies availableupon request) for a period of one year from date of shipments. Cosmetic/visual
defects must be returned to Matrix within 90 days of shipment. Confirmation ofsuch date shall be based on freight documents. The warranty liability of Matrix islimited to repair and/or replacement on the terms set forth above. Matrix will not be
responsible for any subsequent or consequential events.
