5.2 Backlight Unit
5.2.1 Parameter guideline for CCFL
Following characteristics are measured under a stable condition using an inverter at 25
Note 1: IRCFL is defined as the return current of an inverter. (In Figure 1)

A stable IRCFL is a current without flicker or biasing waveform provided by inverter that ensures the
backlight perform to its specification. The ideal sine waveform should be symmetric in positive and negative
polarities and the asymmetry rate of the inverter waveform should be below 10%.
Crest Factor = Ip or (I-p) / Irms should have the range within 1.414 + 10%

DC Bias = (| Ip – I-p| / Irms ) x 100 % <10%
