3.1.1 Absolute Ratings of Environment

If the operating condition exceeds the following absolute maximum ratings, the TFT LCD module may be

damaged permanently.

(Ta=25±2°C, V

=GND=0)

Item Symbol Min. Max. Unit Note

Storage temperature T

STG

-30 80 °C (1)

Operating temperature T

OPR

-20 70 °C (1,2,3)

Note (1) 95 % RH Max. (40°C ≥ Ta). Maximum wet-bulb temperature at 39°C or less. (Ta > 40°C) No

condensation.

Note (2) In case of below 0°, the response time of liquid crystal (LC) becomes slower and the color of

panel becomes darker than normal one. Level of retardation depends on temperature, because

of LC's character

Note (3) Only operation is guarantied at operating temperature. Contrast, response time, another display

quality are evaluated at +25°C.
