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 ~ 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 (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

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 of Max. value is based on 26” backlight unit under 24V input voltage and 7.8mA
lamp in average after lighting for 30 minutes.
Note (7) 10% minimum duty ratio is only valid for electrical operation.
