Discharge characteristics of plasma display panel with box-shaped apertures in transparent dielectric layer

This article presents an improved front panel structure for an alternating current plasma display panel (ac-PDP) based on a transparent dielectric layer with a box-shaped aperture between the sustain electrodes. The suggested structure can reduce driving voltages than conventional ac-PDPs due to a strong electric field between the sustain electrodes. Experiments were conducted with 10% and 20% Xe contents at a gas pressure of 450 Torr , and the results confirmed that the structure with the box-shaped apertures reduced the firing and sustain voltages by about 83.6 and 45.2 V than the conventional structure at 10% Xe content, respectively. Also, the proposed structure with a 20% Xe content improved the luminous efficiency and the luminance by about 21.2% and 19.7%, respectively, when compared to a conventional structure with a 10% Xe content at the same sustain voltage. In addition, the discharge and dynamic characteristics show that the suggested structure is very suitable for high-resolution plasma display panel.
