The Following precautions will guide you in handling our product correctly.
10.Precautions Relating Product Handling
1) Liquid crystal display devices
2) Care of the liquid crystal display module against static electricity discharge.
3) When the LCD module alone must be stored for long periods of time:
4) Use the module with a power supply that is equipped with an overcurrent protector circuit,
5) Do not ingest the LCD fluid itself should it leak out of a damaged LCD module. Should hands
6) Conduc1tivity is not guaranteed for models that use metal holders where solder connections
7) For models which use CFL:
① The liquid crystal display device panel used in the liquid crystal display module is made of plate
② The polarizer adhering to the surface of the LCD is made of a soft material.
① When working with the module, be sure to ground your body and any electrical equipment you may
② Avoid the use of work clothing made of synthetic fibers. We recommend cotton clothing or other
③ Slowly and carefully remove the protective film from the LCD module, since this operation can
① Protect the modules from high temperature and humidity.
② Keep the modules out of direct sunlight or direct exposure to ultraviolet rays.
③ Protect the modules from excessive external forces.
① High voltage of 1000V or greater is applied to the CFL cable connector area.
② Protect CFL cables from rubbing against the unit and thus causing the wire jacket to become worn.
③The use of CFLs for extended periods of time at low temperatures will significantly shorten their
since the module is not provided with this protective feature.
