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 rotate or tilt the signal interface connector of the TFT module when you insert or remove other
connector into the signal interface connector.
9) 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.
