Abstract: An AC plasma display panel (PDP) incorporating the invention includes opposed substrates with an enclosed dischargeable gas positioned therebetween; plural elongated address electrodes positioned on one substrate; and plural scan electrode structures positioned on a second opposed substrate and orthogonally oriented to the address electrodes. A plurality of sustain electrode structures are positioned in parallel configuration and interdigitated with the scan electrode structures. Each sustain electrode structure and scan electrode structure is configured as an elongated conductive layer with plural apertures positioned therein. The elongated conductive layer for each sustain electrode structure and each scan electrode structure may be a cross-hatched conductor pattern or a plurality of parallel conductors connected by shorting bars. Moiré effects of the shorting bars are negated by widely spacing the bars and minimizing their length within a pixel site.

Abstract: An AC PDP incorporating the invention includes a first substrate having plural elongated address electrode structures, which include sets of color phosphors. A second substrate is opposed to the first substrate and encloses a dischargeable gas therebetween. The second substrate supports a plurality of scan loops and sustain loops that are interdigitated with the scan electrode loops. Gas discharges occur at intersections between address electrodes and both traces of a scan loop to which a scan voltage is applied and a single side of each adjacent sustain loop to which a sustain voltage is applied. This action creates wall charges at each of two subpixel sites for each color subpixel. Thereafter, sustain signals applied to sustain and scan electrode loops causes discharges at each of the dual subpixel sites at which wall charges exist. Electrically isolated contrast enhancement bars are placed within scan and sustain electrode loops and act to block ambient light from reflecting off the phosphor layer.

Each scan electrode structure includes a scan loop with a first trace and a second trace and a plurality of sustain electrode structures that are interdigitated with the scan electrode structures, each sustain electrode structure including a first trace and a second trace. Address circuitry selectively applies address signals to the address electrode structures and scan circuitry applies a scan voltage to the scan electrode structures.

Abstract: An energy efficient driver circuit for driving a display panel having panel electrodes and panel capacitance includes an inductor means coupled to the panel electrodes; a driving voltage source; a voltage supply for providing a supply voltage of a magnitude which is greater than the driving voltage; a first switch device for selectively coupling the driving voltage to the inductor in response to a rising input signal transition, the input signal transition commencing a first state wherein a first current flow occurs through the inductor to charge the panel capacitance, the inductor causing the panel electrodes to rise to a voltage in excess of the driving voltage, at which point the first current flow reaches zero; and a second switch device for selectively coupling the voltage supply to the inductor and panel electrodes.
