Plasma display and driving method for plasma display panel

Abstract

In a plasma display panel whose screen size is made larger and higher definition, a first ramp waveform voltage rising from a potential (Vi1) toward a potential (Vi2) is applied to scanning electrodes(SC1 to SCn) in order to stably generate a writing discharge in the initialization period of at least one subfield (first SF) of one field period. A second ramp waveform voltage is also applied to the scanning electrodes (SC1 to SCn) that allows the waveform voltage to immediately drop when it rises from a base potential toward a predetermined potential (Vers) and reaches the predetermined potential (Vers) at the end of the sustain period of each of the subfields (first SF, second SF, ).

Description

technical field [0001] The invention relates to a plasma display device for a wall-mounted TV and a large monitor and a driving method for the plasma display. Background technique [0002] As a plasma display panel (hereinafter referred to as "panel"), in a typical AC surface discharge type panel, a large number of discharge cells are formed between a front panel and a rear panel that are oppositely arranged (confronting). In the front panel, a plurality of display electrode pairs consisting of a pair of scan electrodes and sustain electrodes are formed parallel to each other on a front glass substrate, and a dielectric layer and a protective layer are formed to cover these display electrode pairs. On the rear glass substrate, a number of parallel data electrodes, a dielectric layer covering them, and a plurality of barrier ribs parallel to the data electrodes are formed on the rear glass substrate, and phosphor layers are formed on the surface of the dielectric layer an...

Problems solved by technology

On the other hand, in recent years, the process of further large-screen and high-definition screens has been extremely rapid, and at the same time, there is also a tendency for the drive impedance of the screen to increase.

Moreover, with the increase of the driving impedance of the screen, waveform distortions such as transients are likely to occur in the driving waveform generated by the driving circuit of the screen.

The above-mentioned narrow-width erasing discharge is intended to stabilize the writing operation in the subsequent sub-scanning field, but if, for example, waveform distortion occurs in the drive waveform intended to generate the narrow-width erasing discharge, it may be severely narrowed. Eliminate discharge

In this case, there is a problem that it is difficult to stably generate the subsequent write discharge.
