12 Handling Precautions of the module
The module includes the inverter circuit, which generates high voltage. Do not touch the inverter cover and
CCFT lamp terminals when inverter is turning on. Please alert ”Don’t touch it”,if someone may touch..
a) Be sure to turn off the power supply when inserting disconnecting the cable.
b) This product is using the parts(inverter, CCFT etc) which generate the high voltage. Therefore, during
c) Brightness control voltage is switched for “ON” and “OFF”, as shown in Fig.5. Voltage difference generated
d) Be sure to fix the module in the same plane so that the module can be installed without any extra stress
e) Since the front polarizer is easily damaged, pay attention to treat it.
f) Since long contact with water may cause discoloration or spots, wipe off water drop immediately.
g) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
h) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with
i) Since CMOS LSI is used in this module, take care of static electricity and consider wearing the earth
j) Ground attachment to the LCD module should be considered, so that influences from EMI and outer noise is
k) The module has some printed circuit boards (PCBs) on the back side, take care to keep them form any
l)
m) When some pressure is added onto the module from rear side constantly, it causes display non-uniformity
