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) For enhancing the performance of display in power on initial status, the power consumption will be
increased to 1.5 times and 20 seconds later it will be return to typical value. Thus, the power
source capacity for inverter should be considered to supply the initial power consumption at power
on duration.
Note (7) The backlight turn on voltage should be under the rated withstanding voltage of transformer.
