14. Handling Cautions
14-1) Mounting of module
a) Please power off the module when you connect the input/output connector.
b) Please connect the ground pattern of the inverter circuit surely. If the connection is not
perfect, some following problems may happen possibly.
1.The noise from the backlight unit will increase.
2.The output from inverter circuit will be unstable.
3.In some cases a part of module will heat.
c) Polarizer which is made of soft material and susceptible to flaw must be handled carefully.
d) Protective film (Laminator) is applied on surface to protect it against scratches and dirt’s.
e) Protection film for polarizer on the module shall be slowly peeled off just before use so that
the electrostatic charge can be minimized
14-2) Precautions in mounting
a) When metal part of the TFT-LCD module (shielding lid and rear case) is soiled, wipe it with
soft dry cloth.
b) Wipe off water drops or finger grease immediately. Long contact with water may cause
discoloration or spots.
c) TFT-LCD module uses glass, which breaks or cracks easily if dropped or bumped on hard
surface. Please handle with care.
d) Since CMOS LSI is used in the module. So take care of static electricity and earth yourself
when handling.
14-3) Adjusting module
a) Adjusting volumes on the rear face of the module have been set optimally before
shipment.
b) Therefore, do not change any adjusted values. If adjusted values are changed, the
specifications described may not be satisfied.
14-4) Others
a) Do not expose the module to direct sunlight or intensive ultraviolet rays for many hours.
b) Store the module at a room temperature place.
c) The voltage of beginning electric discharge may over the normal voltage because of
leakage current from approach conductor by to draw lump read lead line around.
d) If LCD panel breaks, it is possibly that the liquid crystal escapes from the panel.
Avoid putting it into eyes or mouth. When liquid crystal sticks on hands, clothes or feet.
Wash it out immediately with soap.
e) Observe all other precautionary requirements in handling general electronic components.
f) Please adjust the voltage of common electrode as material of attachment by 1 module.
