Recovery time should be 24 hours minimum. Moreover, functions, performance and appearance shall be free
from remarkable deterioration within 50,000 hours 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.
14.4 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 isopropyl 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 Newhaven 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.
