11. General Precautions
11.1 Handling
(a) When the module is assembled, it should be attached to the system firmly. Be careful not to twist and bend the module. (b) Refrain from strong mechanical shock and / or any force to the module. In addition to damage, this may cause improper operation or damage to the module and back-light unit. (c) Note that polarizers are very fragile and could be easily damaged. Do not press or scratch the surface harder than a HB pencil lead. (d) Wipe off water droplets or oil immediately. If you leave the droplets for a long time, Staining and discoloration may occur. (e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth. (f) The desirable cleaners are water, IPA(Isopropyl Alcohol) or Hexane. Do not use Ketone type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might permanent damage to the polarizer due to chemical reaction. (g) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In case of contact with hands, legs or clothes, it must be washed away thoroughly with soap. (h) Protect the module from static , it may cause damage to the Integrated Gate Circuit.
(i) Use finger-stalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (j) Do not disassemble the module. (k) Do not adjust the variable resistor which is located on the back side. (l) Protection film for polarizer on the module shall be slowly peeled off just before use so that the electrostatic charge can be minimized. (m) Pins of I/F connector shall not be touched directly with bare hands
