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 voltage should be applied to lamp for more than 1 second to start up,
otherwise backlight may not be turned on.
The inverter of ground floating type should not be used.
