MODULE PRECAUTIONS
1. GENERAL PRECAUTIONS
1.1 Handling
(a) When the module is assembled, It should be attached to the system firmly using every mounting
holes.
Be careful not to twist and bend the modules.
(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 CCFT back-light.
(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 CMOS Gate Array IC.
(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 pull or fold the lamp wire.
(l) Do not adjust the variable resistor which is located on the module.
(m) Protection film for polarizer on the module shall be slowly peeled off just before use so that the
electrostatic charge can be minimized.
(n) Pins of I/F connector shall not be touched directly with bare hands.
1.2 Storage
(a) Do not leave the module in high temperature, and high humidity for a long time. It is highly
recommended to store the module with temperature from 0 to 35C and relative humidity of less than
70%.
(b) Do not store the TFT-LCD module in direct sunlight.
