Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] One embodiment of the present invention provides a driving method for a plasma display. The plasma display includes a plurality of row scanning electrodes, a plurality of column address electrodes, and a common electrode. The display mode of the plasma display is that one field is divided into a plurality of Each subfield is divided into a reset period, a scan-address period and a sustain period, including the following steps: forming an overlapping portion in phase between the Y sustain period of the row scan electrodes and the X sustain period of the column address electrodes.

[0026] The driving method of the above embodiment introduces waveform overlap in individual cycles on the driving waveforms of the driving electrodes X and Y, and conducts orderly distribution in the entire sustaining cycle, so that the frequently cha...

Abstract

The invention provides a drive method for a plasma display. The plasma display comprises a plurality of line scanning electrodes, a plurality of row addressing electrodes and a public electrode. The plasma display has the display way that a field is divided into a plurality of subfields, and each subfield is divided into a reset period, a scanning-addressing period and a maintaining period. The method comprises the following step of: forming a same-phase overlapping part between a Y maintaining period of the line scanning electrodes and an X maintaining period of the row addressing electrodes. The invention introduces wave shape overlapping in an individual period on an X drive wave shape and a Y drive wave shape of a drive electrode and carries out sequential distribution in the whole maintaining period, therefore, the wall charge with frequent change can be effectively adjusted, the residual charge and space retaining charge are reduced, and the optimal image quality can be ensured.

Description

technical field [0001] The invention relates to the field of plasma displays, in particular to a driving method for the plasma display. Background technique [0002] A color plasma display (PDP, Plasma Display Panel) is a display device that has developed rapidly in recent years. Color plasma display has become the first choice for large-screen display devices due to its superior performance. At present, large-screen color plasma display devices have begun to enter the market, especially the AC-type AC-PDP has been extensively researched and applied due to its simple driving method and other advantages. And it will gradually become popular in recent years. [0003] The plasma display screen is coated under the action of ultraviolet rays generated during the discharge of inert gases such as helium + xenon (He+Xe), neon + xenon (Ne+Xe), helium + neon + xenon (He+Ne+Xe) The phosphor emits light to display the image. This kind of PDP can not only be made thinner and larger, b...
