(a) 90 %RH Max. (Ta Љ 40 ºC).
(b) Wet-bulb temperature should be 39 ºC Max. (Ta > 40 ºC).
(c) No condensation.
Note (2) The maximum operating temperature is based on the test condition that the surface temperature of
display area is less than or equal to 65 ºC with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in final product design to prevent the surface temperature of
display area from being over 65 ºC. The range of operating temperature may degrade in case of
improper thermal management in final product design.

Unit Note
Note (5) At testing Vibration and Shock, the fixture in holding the module has to be hard and rigid enough so that
the module would not be twisted or bent by the fixture.
