14.3 Reliability of LCM
Reliability test condition:
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+8qC), normal humidity (below 65% RH), and in the area not exposed to direct sun light.

LCD/LCM is assembled and adjusted with a high degree of precision. Do not attempt to make
1. LCD panel is made of glass. Avoid excessive mechanical shock or applying strong
2. The polarizer used on the display surface is easily scratched and damaged. Extreme care
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
6. Avoid pressing on the metal bezel, otherwise the elastomer connector could be deformed
7. Be careful not to touch or swallow liquid crystal that might leak from a damaged cell. Any liquid crystal
