2. ABSOLUTE RATINGS OF ENVIRONMENT
Note
(1) Temperature and relative humidity range is shown in the figure below.
(a) 90% RH Max. (Ta ≦40ºC)
(b) Wet-bulb temperature should be 39ºC Max. (Ta ＞ 40ºC)
(c) No condensation.
(2)The maximum operating temperature is based on the test condition that the
surface temperature of display area is less than or equal to 60ºC with LCD
module alone in a temperature controlled chamber. Thermal management
should be considered in final product design to prevent the surface tempera-
ture of display area from being over 60ºC. The range of operating tempera-
ture may degrade in case of improper thermal management in final product
design.
(3) 11 ms, half sine wave, 1 time for ±X, ±Y, ±Z.
(4)10~200 Hz, 10 min, 1 time each X, Y, Z.
(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.
