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.

Note (2) The lamp starting voltage V
should be applied to the lamp for more than 1 second under starting
S
up duration. Otherwise the lamp could not be lighted on completed.
Note (3) The lamp frequency may produce interference with horizontal synchronous frequency of the
display input signals, and it may result in 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 of lamp.) as the time in which it continues to operate under the
condition at Ta = 25 2к and I

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 (6) The measurement condition of Max. value is based on 31.5" backlight unit under input voltage 24V,
average lamp current 5.5 mA and lighting 30 minutes later.
