(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.

and IL = 4.5 ~ 5.5 mArms.
Note (5) The power supply capacity should be higher than the total inverter power consumption PBL. Since
the pulse width modulation (PWM) mode was applied for backlight dimming, the driving current
changed as PWM duty on and off. The transient response of power supply should be considered
for the changing loading when inverter dimming.

Note (1) The SEL signal should be valid before backlight turns on by BLON signal. It is inhibited to change
the internal/external PWM selection (SEL) during backlight turn on period.
Note (2) The power sequence and control signal timing are shown in the following figure.
Note (3) The power sequence and control signal timing must follow the figure below. For a certain reason,
the inverter has a possibility to be damaged with wrong power sequence and control signal
timing.
