BACKLIGHT CHARACTERISTICS
This module is used the backlight with 4 CFL.
Please follow the characteristics of 1 CFL as below.
Ta= 25qC

Lamp voltage VL- 570 - Vrms at IL=6.0mArms
Lamp current IL3 - 8 mArms

[ Note 1 ] Backlight driving conditions (operating frequency fL especially) may interfere with
horizontal frequency f
operating frequency f
, causing the beat or flicker on the display. Therefore the
H
shall be adjusted in relation to horizontal frequency fH to
L
avoid interference. And please make sure that frequency, phase of Drive voltage
and current of four lamps, match each other.
[ Note 2 ] The inverter open voltage should be larger than start up voltage, otherwise
backlight may blinking for a moment after turns on or not be turned on. And this
voltage should be applied to lamp for more than 1 second to start up, otherwise
backlight may not be turned on.
[ Note 3 ] If driving current waveform is asymmetrical, mercury deviation inside of CFL will
incline to one side and consequently abnormal lighting may occur.
To prevent such unfavorable lighting, driving current waveform is asked to have
unbalance rate of less than 10% and wave-height rate of less than C2 r 10%.
And this driving waveform shall be confirmed in your system.
Unbalance rate = | Ip - I-p | / IL u 100 (%)

[ Note 4 ] The inverter of ground reference type should be used. The inverter of ground
floating type should not be used.
