12. PRECAUTION FOR USING LCD/LCM
After reliability test, recovery time should be 24 hours minimum. Moreover, functions, performance
and appearance shall be free from remarkable deterioration within 50,000 hours（average） under
ordinary operating and storage conditions room temperature (20+8°C), normal humidity (below 65%
RH), and in the area not exposed to direct sun light. Using LCM beyond these conditions will
shorten the life time.
Precaution for using LCD/LCM
LCD/LCM is assembled and adjusted with a high degree of precision. Do not attempt to make any
alteration or modification. The followings should be noted.
General Precautions:
1. LCD panel is made of glass. Avoid excessive mechanical shock or applying strong pressure onto
the surface of display area.
2. The polarizer used on the display surface is easily scratched and damaged. Extreme care should
be taken when handling. To clean dust or dirt off the display surface, wipe gently with cotton, or
other soft material soaked with isoproply alcohol, ethyl alcohol or trichlorotriflorothane, do not
use water, ketone or aromatics and never scrub hard.
3. Do not tamper in any way with the tabs on the metal frame.
4. Do not make any modification on the PCB without consulting DISPLAY.
5. When mounting a LCM, make sure that the PCB is not under any stress such as bending or
twisting. Elastomer contacts are very delicate and missing pixels could result from slight
dislocation of any of the elements.
6. Avoid pressing on the metal bezel, otherwise the elastomer connector could be deformed and
lose contact, resulting in missing pixels and also cause rainbow on the display.
7. Be careful not to touch or swallow liquid crystal that might leak from a damaged cell. Any liquid
crystal adheres to skin or clothes, wash it off immediately with soap and water.
Static Electricity Precautions:
1. CMOS-LSI is used for the module circuit; therefore operators should be grounded whenever
he/she comes into contact with the module.
2. Do not touch any of the conductive parts such as the LSI pads; the copper leads on the PCB and
the interface terminals with any parts of the human body.
3. Do not touch the connection terminals of the display with bare hand; it will cause disconnection
or defective insulation of terminals.
