DESCRIPTION:
BRIEF SUMMARY
DESCRIPTION
Technical Field
The invention relates to gas-discharge engineering and, in particular, to gas-discharge engineering that can be used in display systems such as AC PDPs and color TV gas-discharge videomodules.
BACKGROUND OF THE INVENTION
The following known plasma display panels lack a desired technical result when used.
1) There is a known alternating current plasma display panel (AC PDP) with a surface discharge where each pixel is comprised of two parallel electrodes arranged on one glass plate and drive electrodes perpendicular to them arranged on another plate separated by dielectric barrier ribs. See EP 05541724A1.
2) There is a known method of driving an alternating current plasma display panel with a surface discharge consisting of a) address pulses on one of the parallel and drive electrodes of a pixel and b) discharge sustain pulses on the parallel electrodes. Primary discharges are formed in all pixels of the plasma panel before application of address pulses. See EP 0549275A1.
3) There is a known alternating current plasma display panel comprising in each pixel two parallel electrodes arranged on one glass plate and drive electrodes perpendicular to them, the latter being arranged on another plate and separated by dielectric barrier ribs. The adjacent pixels being also separated by dielectric barrier ribs arranged along the parallel electrodes. See T. Nakamura, "Drive for 40 in Diagonal Full-Color AC Plasma Display" SID '95 Digest, pp 807-810.
4) There is a known method of AC plasma display panel driving with a surface discharge consisting of a) address pulses on one of the parallel electrodes and one drive electrode per pixel and b) discharge sustain pulses where primary discharges are formed in the part of plasma display panel pixels prior to address pulses application. See T. Nakamura, "Drive for 40 in Diagonal full color AC Plasma Display" SID 95 DIGEST, pp 807-810.
5) The closest device of the same purpose as the invention as to totality of features is an AC Plasma display panel with a surface discharge comprising in each pixel, three parallel electrodes, one of them being an address one, and perpendicular to them, drive electrodes separated by dielectric barrier ribs. See U.S. Pat. No. 4,914,352.
6) The closest method of the same purpose as the method of the invention as to totality of features is the method of driving of an alternating current plasma display panel with a surface discharge consisting in formation of pulses, primary, address and discharge sustain on the electrodes. See U.S. Pat. No. 4,914,352.
DISCLOSURE OF INVENTION
Reasons for the lack of achievement of the desired technical result when using the known plasma display panels 1), 2), 3), 4), 5), and 6) above is the fact that in these methods there are no conditions for improving effectiveness.
The essence of the invention is as follows.
The invention solves the objectives of improving operating parameters of display systems comprising AC plasma display panels.
When performing the invention, a single technical result can be achieved, namely, the increase in effectiveness which is determined by a ratio of a light flux emitted by a plasma display panel in the direction toward a viewer to power consumption of a plasma display panel.
The technical result is achieved by the fact that there is in the inventive device: pixel three parallel electrodes with one of them being an address one, and drive electrodes being perpendicular to them and separated by dielectric barrier ribs; fixed from conditions of performance of a surface discharge in a pixel between two extreme parallel electrodes over the address electrode arranged between them; and dm=pixel address electrode width, de=pixel extreme parallel electrode width; the distance between adjacent edges of the parallel electrodes set from the radio a/b is 0.5 to 1.5, where a=the distance between 30 edges of the address and one of the extreme parallel electrodes of a pixel, b=the distance between edges of the address and the other extreme parallel electrode of a pixel
