Note (1) Temperature and relative humidity range is shown in the figure below.
(a) 90 %RH Max. (Ta
≦
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 60 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 60 ºC. The range of operating temperature may degrade in case of improper
thermal management in final product design.
Note (3) 11 ms, half sine wave, 1 time for ± X, ± Y, ± Z.
Note (4) 10 ~ 200 Hz, 10 min, 1 time each X, Y, Z.
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.
