10. Display Quality
The display quality of the color TFT-LCD module shall be compliance with the incoming inspection standard.
11. Warning
The module includes the inverter circuit, which generates high voltage. Do not touch the inverter cover and
CCFT lamp terminals in current carrying. Clearly, alert the possibility of the inverter touched by someone.
12. Handling Precautions of the module
a)
Be sure to turn off the power supply when inserting or disconnecting the cable.
b)
Brightness control voltage is switched for “ON” and “OFF”, as shown in Fig.4. Voltage difference generated
by this switching,
V
INV,
may affect a sound output, etc. when the power supply is shared between the
inverter and its surrounding circuit. So, separate the power supply of the inverter circuit with the one of its
surrounding circuit.

c)
Be sure to fix the module in the same plane so that the module can be installed without any extra stress such
as warp or twist.
d)
Since the front polarizer is easily damaged, pay attention to treat it.
e)
Since long contact with water may cause discoloration or spots, wipe off water drop immediately.
f)
When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
g)
Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with
care.
h)
Since CMOS LSI is used in this module, take care of static electricity and consider wearing the earth
personnel when handling.
i)
Observe all other precautionary requirements in handling components.
j)
Blow off dust with N2 blower for which static electricity preventive measure has been taken. Ionized air gun
is recommended.
