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%.
(1) Measurement equipment : BM-7(TOPCON Corp.), Field=2 degree
(2) Ambient temperature : 25 +/- 2 degC
(3) LCD : All pixels are WHITE, VDD=3.3V, fV=60Hz
(4) Measure after 30 minutes of CFL warm up.
(5) IL=3.5 mArms with the CFL inverter CFP-66-5.
