Abstract
This paper presents the effects of various driving waveforms on the discharge characteristics of the Hg-free backlight unit (BLU). First, the square-type and sine-type waveforms are compared. The sine-type driving waveform shows the unstable discharge characteristics even at a higher driving voltage condition. Next, for the square-type driving waveform, two types of square-type waveform, that is, with and without a transformer, are examined. Finally, for the two types of square-type waveform, the effects of duty ratio on the luminance, consumption power and luminous efficiency are examined in detail.
