Note 1. Ta at -20 C --------< 48hours, at 70 C --------< 120 hours.

Note 2. Background color changes slightly depending on ambient temperature.
This phenomenon is reversible.

Note 3. When LCM is operated at 0 C, the lifetime of the CFL will be reduced.

The response time at 0 C will increase.

Note 4. Ta<=50 C : 85%RH MAX.

Ta> 50 C : Absolute humidity must be lower than the humidity of 85% RH at 50 C.

6.3 Power Supply and Signal Sequence

Do not apply DC voltage to the LCD panel because this induces an electrochemical

reaction and reduces its lifetime. Please follow the power supply ON/OFF sequence below
to prevent DC driving of the LCD or latch-up of the LSIs.
