(1) 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 to 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 remove the electroluminescent panel from the PC board, be sure the solder has completely
melted, the soldered pad on the PC board could be damaged.
Precautions for Operation
(1) Viewing angle varies with the change of liquid crystal driving voltage (VLCD). Adjust VLCD to show the best
contrast.
(2) It is an indispensable condition to drive LCD's within the specified voltage limit since the higher voltage then
the limit cause the shorter LCD life. An electrochemical reaction due to direct current causes LCD's undesirable
deterioration, so that the use of direct current drive should be avoided.
(3) Response time will be extremely delayed at lower temperature than the operating temperature range and on the
other hand at higher temperature LCD's show dark color in them. However those phenomena do not mean malfunction
or out of order with LCD's, Which will come back in the specified operating temperature.
(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) A slight dew depositing on terminals is a cause for electro-chemical reaction resulting in terminal open circuit.
Usage under the maximum operating temperature, 50%RH or less is required.
(6) Input logic voltage before apply analog high voltage such as LCD driving voltage when power on. Remove
analog high voltage before logic voltage when power off the module. Input each signal after the positive/negative voltage
becomes stable.
(7) 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.
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 leaks 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 TRULY and customer, TRULY will replace or repair any of its LCD modules which are
found to be functionally defective when inspected in accordance with TRULY LCD acceptance standards (copies
available upon request) for a period of one year from date of production. Cosmetic/visual defects must be returned to
TRULY within 90 days of shipment. Confirmation of such date shall be based on data code on product. The warranty
liability of TRULY limited to repair and/or replacement on the terms set forth above. TRULY 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 is damaged or modified.
- PCB conductors damaged.
- Circuit modified in any way, including addition of components.
- PCB tampered with by grinding, engraving or painting varnish.
- Soldering to or modifying the bezel in any manner.
