Analysis of luminance variation with display load and display pattern in AC-plasma display panels
The luminance variance according to the display load was found to be mainly due to a distortion of the sustain waveform. In particular, the distortion of the rising slope of the sustain waveform according to the display load was shown to affect the sustain discharge characteristics, thereby varying the luminance of the ac-PDP. Therefore, the luminance variation relative to the display load was significantly compensated by proper control of the rising slope of the sustain waveform according to the display load.
