We have developed a display device that has a large-area, full-color flat screens and consists of many cells fabricated together on a single glass sheet. The device utilizes a Xe dielectric barrier discharge similar to the process used in plasma display panel. We have already reported on 64-inch display system employing 10-mm-pixel-pitch devices, at IDW'99. We have recently developed a 6-mm-pixel-pitch device. This paper describes the method of operation of these devices. The operating voltage margins were formulated by considering gas dielectric barrier discharges, and they were compared with the experimental data. There is an optimum operating frequency at which the device achieves maximum efficiency. The optimum operating frequency is 125 kHz in the case of a 6-mm-pixel-pitch device. In this operating method, a biasing voltage is added to a common electrode voltage pulse to reduce the required addressing voltage. The addressing voltage has thus been decreased by 50 V with respect to the conventional device for a given sustain voltage. The threshold addressing voltage is only 30 V for a 10-mm-pixel-pitch device.
