The new facing reset discharge waveform is designed and proposed to reduce a dark image sticking in AC‐PDP. In particular, the influences of two types of reset discharge (surface reset and facing reset discharges) on dark image sticking are investigated intensively. It is observed that the dark image sticking is reduced considerably when a reset discharge is produced between the scan and address electrodes instead of between the scan and sustain electrodes during a reset‐period.
In this paper, a new driving scheme is proposed to improve the luminous efficiency using a self‐erasing discharge during a sustain‐period in an AC PDP. The self‐erasing discharge is produced between successive sustain pulses by simultaneously applying the short address pulses at the falling edge of the sustain pulses, thereby resulting in improving the luminous efficiency without reducing the luminance. It is found that this new driving scheme can improve the luminous efficiency by 37.5 % and the luminance by 3.5 %, when compared with the conventional driving scheme of an AC PDP.
In this paper, we present a new reset waveform for a large‐sustain‐gap structure in ac PDPs. In the driving of the large‐sustain‐gap structure with a conventional ramp reset waveform, we cannot avoid the condition of an address being a cathode, which causes lots of trouble in stabilizing a reset discharge. To solve these problems, we use the square pulse instead of the conventional rising ramp pulse. Before making a strong discharge between the address (cathode) and scan (anode) electrodes, we make a priming discharge between the address (anode) and the scan (cathode) electrodes to stabilize the strong discharge in which the address electrodes are the cathode. With this scheme, we obtained 60V minimum address voltage and 145V maximum address voltage in 250μm and 350μm gap structures.
