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 2 +/- 10%.
And this driving waveform shall be confirmed in your system.
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.
