(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.
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.

Note (1) The Dimming signal should be valid before backlight turns on by BLON signal. It is inhibited to
change the internal/external PWM signal during backlight turn on period.
Note (2) The power sequence and control signal timing are shown in the following figure. For a certain
reason, the converter has a possibility to be damaged with wrong power sequence and control
signal timing.
Note (3) While system is turned ON or OFF, the power sequences must follow as below descriptions:
Turn ON sequence: VBL Ш PWM signal Ш BLON
Turn OFF sequence: BLOFF Ш PWM signal Ш VBL
