Cell geometry designs for efficient plasma display panels

Abstract

Summary form only given, as follows. We use a two-dimensional self-consistent simulation model to study the effect of the geometric parameters on the operating voltages and the efficiency of a coplanar-electrode plasma display panel cell. For the standard coplanar-electrode geometry it is found that there is a trade-off between high efficiency and low operating voltages as the electrode gap, or other parameters of the upper dielectric are varied, while variation of the sustain electrode width has no significant effect on either the operating voltages or efficiency. We also investigate the performance of several non-standard cell geometry designs involving two-dimensional variations of the coplanar-electrode PDP cell. A PDP cell with modified shape of sustain electrodes is found to have /spl sim/20% larger luminous efficiency without substantial increase of the operating voltages. Similar performance improvement is achieved by designs with different shapes of the upper dielectric, or by those involving two different dielectric layers. The dependence of PDP performance on the design parameters of these structures is also investigated.
