(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, 30 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.

2.2 PACKAGE STORGE
When storing modules as spares for a long time, the following precaution is necessary.
(a) Do not leave the module in high temperature, and high humidity for a long time. It is highly recommended to
store the module with temperature from 0 to 35кat normal humidity without condensation.
(b) The module shall be stored in dark place. Do not store the TFT-LCD module in direct sunlight or
fluorescent light.

Note (1) The power supply capacity should be higher than the total converter 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 converter dimming.
Note (2) The measurement condition of Max. value is based on 31.5" backlight unit under input voltage 24V,
average LED current 127.2 mA and lighting 1 hour later.
Note (3) The duration of rush current is about 30ms.
Note (4) 5% minimum duty ratio is only valid for electrical operation.

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.
