And this voltage should be applied to lamp for more than 1 second to start up,
otherwise backlight may not be turned on.
incline to one side and consequently abnormal lighting may occur.
To prevent such unfavorable lighting, driving current wave form is asked to have
unbalance rateof less than 10% and wave-height rateoflessthan 2 +/- 10%.
And this driving wave form shall be confirmed in your system.
