Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing driving method is prone to cause misfire and affect the display quality due to the uneven wall charge generated in the discharge cells, and to invent a method that does not care about the discharge of each cell in the previous subfield during the recovery period. No matter how the state is, after the recovery period, all the cells can get stable and uniform wall charges. The driving method of the slot-type plasma display panel

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] As shown in Figures 1-7.

[0026] A method for driving a slot-type plasma display panel. During the recovery period for initializing the distribution of wall charges in each discharge cell in a subfield of each display frame, while applying a recovery pulse to a sustain electrode (that is, an X electrode), the subsequent A pulse voltage is correspondingly applied to the substrate addressing electrode (i.e., A electrode) to form a new composite recovery pulse as the recovery voltage pulse of the slot-type plasma display, so that each discharge cell in the full screen is sufficiently accumulated to the previous display state. Independent stable uniform wall charge. The reliability of the entire screen when displaying images of the slot-type plasma display panel is further improved.

[0027] During specific implementation, while applying a reset p...

Abstract

The invention discloses a wall electric charge in a recovery period of an erasing period of a groove type plasma display according to the characteristic of phase discharge by two electrodes in existing groove type plasma display, which forms an electric field by applying a pulse voltage via a rear basal plate addressing electrode (electrode A), generates impact on a display unit of the groove type plasma display in the recovery period, eliminates the impact of wall electric discharge accumulated in an ignited unit in a front sub-field and ensures each discharge unit in the full screen to accumulate to a status irrelevant to previous display status. Therefore, the invention further enhances the reliability and display quality of the groove type plasma display panel and realizes the object of making the groove type plasma display panel the display of next generation.

Description

technical field [0001] The invention relates to a driving method of a groove type plasma display panel. Background technique [0002] The plasma flat panel display (PDP), which emerged in the early 1990s, has attracted widespread attention for its advantages of digitization, large screen, high resolution, high definition, wide viewing angle, thin thickness and light weight. [0003] Existing slot-type plasma display panel (SM-PDP) adopts two electrodes which are the sustain electrode (X electrode) on the front substrate respectively; the AC opposite discharge mode of the address electrode (A electrode) on the rear substrate . In the reset period in the erase period of SM-PDP, a composite high-voltage pulse is applied to the sustain electrode (X electrode) of the front substrate, while the address electrode (A electrode) is kept at the ground voltage state (0V). Participate in the accumulation of wall charges, in order to obtain stable wall charges, make the full screen in ...
