Unit Note
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 (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.

2.2 PACKAGE STORAGE
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 35 at normal humidity without condensation.к
(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 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.
