1.0 Handling Precautions
1) Do not press or scratch the surface harder than a HB pencil lead because the polarizers are very fragile
and could be easily damaged.
2) Be sure to turn off power supply when inserting or disconnecting from input connector.
3) Wipe off water droplets or oil immediately. Long contact with the droplets may cause discoloration or
spots.
4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
6) Protect the module from static electricity and insure proper grounding when handling. Static electricity
may cause damage to the CMOS Gate Array IC.
7) Do not disassemble the module.
8) Do not press the reflector sheet at the back of the module.
9) Avoid damaging the TFT module. Do not press the center of the CCFL Reflector when it was taken out
from the packing container. Instead, press at the edge of the CCFL Reflector softly.
10) Do not rotate or tilt the signal interface connector of the TFT module when you insert or remove other
connector into the signal interface connector.
11) Do not twist or bend the TFT module when installation of the TFT module into an enclosure (Notebook
PC Bezel, for example). It should be taken into consideration that no bending/twisting forces are applied
to the TFT module from outside when designing the enclosure. Otherwise the TFT module may be
damaged.
12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local regulations for
disposal.
13) The LCD module contains a small amount of material that has no flammability grade, so it should be supplied
by power complied with requirements of limited power source (2.11, IEC60950 or UL1950).
14) The CCFL in the LCD module is supplied with Limited Current Circuit (2.4, IEC60950 or UL1950). Do not
connect the CCFL in Hazardous Voltage Circuit.
