3) Frequency of the vibration is between 15 Hz and 100 Hz. (Remove the resonance point)
4) Pulse width of the shock is 10 ms.
5) The temperature of LCD front surface would be 65 㷄 in operating, it may affect the optical
characteristics however it does not damage the function of the module.
6) Environmental Absolute Maximum Ratings is based on Panasonic Liquid Crystal Display Co., Ltd.
TFT-LCD module.
If the TFT-LCD cell is left alone, this environmental ratings can't be guaranteed.
The users have a responsibility in considering ability of other parts of TFT-LCD module and its process.
1.3 Environmental Absolute Maximum Ratings of TFT-LCD cell
1) Storage Condition : With shipping package
2) Storage temperature range : 25±5 㷄
3) Storage humidity range : 50±10䋦RH

2. INITIAL OPTICAL CHARACTERISTICS
The following optical characteristics are measured under stable conditions. It takes about 30 minutes
to reach stable conditions. The measuring point is the center of display area unless otherwise noted.
The optical characteristics should be measured in a dark room or equivalent state.
