Appendix A Appendix A Handling the LCD Module Precautions for handling the LCD module The LCD module can be easily damaged during assem bly or disassembly.
3. If the panel’s surface gets dirty, wipe it with cotton or a soft cloth. If it is still dirty, try breathing on the surface to create a light condensate and wipe it again. If the surface is very dirty, we recommend a CRT cleaning agent. Apply the agent to a cloth and then wipe the panel’s surface.
5. Glass is used in the panel, so be careful not to drop it or let it strike a hard object, which could cause breakage or cracks. 6. CMOS-LSI circuits are used in the module, so guard against damage from electrostatic discharge. Be sure to wear a wrist or ankle ground when handling the module.
7. Do not expose the module to direct sunlight or strong ultraviolet rays for long periods. 8. Do not store the module at temperatures be low specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage.
10. If you transport the module, do not use packing material that contains epoxy resin (amine) or silicon glue (alcohol or oxime). These materials can release gas that can dam age the panel’s polarization.
