Method for driving plasma display panel

The present invention relates to a method and apparatus for driving a plasma display panel that can be driven at a low voltage and prevent undesired discharge from being generated under high temperature environment.

Method and apparatus for driving plasma display panel

A plasma display device includes: a dielectric layer on which a plurality of through-holes of a dielectric layer is disposed in a matrix shape; upper and lower electrode layers formed at both upper and lower surfaces of the dielectric layer; upper and lower substrates disposed on the outer surface of the upper and lower electrode layers; and a third electrode layer having a plurality of third electrodes which are formed between the upper substrate and the upper electrode layer, or the lower substrate and the lower electrode layer, and are insulated from the upper and lower electrode layers. Accordingly, a plasma display device can be realized which has stability and efficiency of a micro discharge. In addition, each pixel can concurrently carry out a sustain discharge by applying an alternating voltage to upper and lower electrodes forming sustain electrodes.

Plasma Display Panel

A method for driving a plasma display panel including discharge cells formed at the intersections of the scan electrodes, maintaining electrodes, and data electrodes. One field consists of a plurality of sub fields, each having an initialization period, a write period, and a maintaining period. The maintaining period of at least one sub field has a first maintaining period during which the maintaining pulse has a first rise time and a second maintaining period during which the maintaining pulse has a second rise time shorter than the first rise time. The second maintaining period includes at least the final period of the maintaining period.

Plasma display panel drive method

A method of driving a plasma display panel that is adaptive for improving a picture quality. In the method, first and second sustain pulses having a different width during the sustain period are alternately applied to the first and second row electrodes.

PROBLEM TO BE SOLVED: To provide a high picture quality, more specifically high definition, gradation and brightness, enhanced display quality, and high contrast. SOLUTION: An electrode driving circuit performs interlaced scanning so that the odd- and even-numbered lines of surface-discharge electrode spacings L1 to L8 have their maintaining pulse voltage waveforms set in opposite phase to each other. Thus, when either the odd- or even-numbered line is displayed, the voltage applied to the other electrode spacing becomes zero, eliminating the need to provide bulkheads over the surface-discharge electrodes. As the surface-discharge electrodes, an X (X1 to X5) electrode is placed on each side of a Y (Y1 to Y4) electrode, and the display line of an odd-numbered frame is set between the Y electrode and the X electrode on one side and supplied with a maintaining pulse while the display line of an even- numbered frame is set between the Y electrode and the X electrode on the other side and supplied with a maintaining pulse. Blind lines are set at every other spacing between the surface-discharge electrodes, and at the blind lines, light emitted from a discharge is blocked or external light is absorbed. A plurality of address electrodes are arranged on one line of picture elements and are selectively connected to a pad thereon so that a plurality of the lines can be selected simultaneously.

PROBLEM TO BE SOLVED: To make further high gradation and brightness and better black display quality or high contrast. SOLUTION: Surface discharge electrodes containing X-electrodes and Y- electrodes are alternately arranged in parallel and shading masks 41-43 are formed alternately between the surface discharge electrodes to be blind rows B1-B3 so that discharge emission in the blind rows can be shaded. In a resetting period, voltage is applied between the electrodes constituting the blind rows B1-B3 so that voltage applied between the electrodes constituting display rows L1-L4 can be in-phase, to cause priming discharge. The surfaces on the observer' s side of the shading masks 41-43 are colored black, by which outside light is absorbed. Plural address electrodes are arranged in one picture element column and selectively connected to pads located thereon so that plural rows can be selected at the same time.
