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 ~ 500 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 (2) The lamp starting voltage VS should be applied to the lamp for more than 1 second under starting
up duration. Otherwise the lamp could not be lighted on completed.
Note (3) The lamp frequency may produce interference with horizontal synchronous frequency from the
display, and this may cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronous frequency and its harmonics as far
as possible.

Note (4) The life time of a lamp is defined as when the brightness is larger than 50% of its original value
and the effective discharge length is longer than 80% of its original length (Effective discharge
length is defined as an area that has equal to or more than 70% brightness compared to the
brightness at the center point.) as the time in which it continues to operate under the condition Ta

Note (1) When inverter protective function is triggered, ERR will output open collector status. In normal
operation, the signal of ERR will output a low level voltage.
Note (2) The power sequence and control signal timing are shown in the following figure. For a certain
reason, the inverter 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:
