Handling the LCD Module Appendix A Appendix A Handling the LCD Module Precautions for handling the LCD module The LCD module can be easily damaged during assembly or disassembly. Observe the following precautions when handling the LCD module: 1. When installing the LCD module in the LCD cover, be sure to seat it so that it is properly aligned and maximum visibility of the display is maintained.
Page 240 Handling the LCD Module 3. If the panel’s surface gets fingerprint or dust, put on gloves and wipe it with static electricity cloth. If it is still dirty, drop some cleaning alcohol on the surface and wipe it again. If the surface is much more fingerprint or dust, we recommend a CRT cleaning agent. Apply the agent to a cloth and then wipe the panel’s surface.
Page 241 Handling the LCD Module 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. Satellite L600D/L640D/L645D, Satellite Pro L600D/Pro L640D/Pro L645D Maintenance Manual (960-Q08)
Page 242 Handling the LCD 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 below specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage. 9.
Page 243 Handling the LCD Module 10. If you transport the module, do not use packing material that contains epoxy resin (amine) or silicon glue (alcohol or oxide). These materials can release gas that can damage the panel’s polarization. Satellite L600D/L640D/L645D, Satellite Pro L600D/Pro L640D/Pro L645D Maintenance Manual (960-Q08)
