4.3.1 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.
4.3.2 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.
4.3.3 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.
4.4 Precautions for Operation
4.4.1 Viewing angle varies with the change of liquid crystal driving voltage (VLCD). Adjust
VLCD to show the best contrast.
4.4.2 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.
4.4.3 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.
4.4.4 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.
4.4.5 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.
4.4.6 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.
4.4.7 Please keep the temperature within the specified range for use and storage. Polarization
degradation, bubble generation or polarizer peel-off may occur with high temperature and
high humidity.
4.5 Safety
4.5.1 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.
4.5.2 If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash
off thoroughly with soap and water.
