LCD MODULE

(4)Soldering iron is not allowed to touch the surface of FPC’s cover film directly.
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 shortens its life.
(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 back 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.
Storage
When storing LCDs as spares for some years, the following precaution are necessary.
(1) Store them in a sealed polyethylene bag. If properly sealed, there is no need for dessicant.
(2) Store them in a dark place. Do not expose to sunlight or fluorescent light, keep the temperature between
0°C and 35°C.
(3) The polarizer surface should not come in contact with any other objects. (We advise you to store them in
the container in which they were shipped.)
(4) Environmental conditions :
- Do not leave them for more than 160hrs. at 70°C.
- Should not be left for more than 48hrs. at -20°C.
Safety
(1) It is recommended to crush damaged or unnecessary LCDs into pieces and wash them off with solvents
such as acetone and ethanol, which should later be burned.
(2) If any liquid leakes out of a damaged glass cell and comes in contact with the hands, wash off thoroughly
with soap and water.
Limited Warranty
Unless agreed between EAST and customer, EAST will replace or repair any of its LCD modules which are
found to be functionally defective when inspected in accordance with EAST LCD acceptance standards (copies
available upon request) for a period of one year from date of shipments. Cosmetic/visual defects must be
returned to EAST within 90 days of shipment. Confirmation of such date shall be based on freight documents.
The warranty liability of EAST limited to repair and/or replacement on the terms set forth above. EAST will not
be responsible for any subsequent or consequential events.
Return LCM under warranty
No warranty can be granted if the precautions stated above have been disregarded. The typical examples of
violations are :
- Broken LCD glass.
- PCB eyelet’s damaged or modified.
