Driving method of plasma display panel and plasma display device

Abstract

A method for driving a plasma display panel including a plurality of scan electrodes, a plurality of sustain electrodes, and a plurality of address electrodes crossing the scan electrodes and the sustain electrodes. A voltage which is greater than a sustain-discharge pulse voltage and less than a voltage obtained by subtracting the sustain-discharge pulse voltage from two times a discharge firing voltage is applied to at least one of the scan electrodes in a reset period of at least one subfield of a plurality of subfields forming a field. At this time, the voltage applied to the at least one of the scan electrodes can be applied as a pulse-type voltage or as a gradually increasing voltage.

Description

technical field [0001] The present invention relates to a method of driving a plasma display panel (PDP). Background technique [0002] A PDP is a flat panel display that displays characters or images using plasma generated by gas discharge, and includes hundreds of thousands to millions of pixels in a matrix, where the number of pixels is determined by the size of the PDP. refer to figure 1 with figure 2 Describe the structure of a conventional plasma display. [0003] figure 1 represents a portion of the perspective view of the plasma display, and figure 2 Indicates the electrode arrangement of the plasma display. [0004] Such as figure 1 As shown, the plasma display screen includes two glass substrates 1 and 6 . Multiple pairs of parallel scan electrodes 4 and sustain electrodes 5 are formed on the first glass substrate 1 and covered with a dielectric layer 2 and a protective film 3 . A plurality of address electrodes 8 are formed on the second glass substrate ...

AI Technical Summary

Problems solved by technology

However, wall charge loss often occurs due to mutual interference caused by adjacent cell discharges and spontaneous disappearance of wall charges caused by internal fields in cells that do not generate sustain discharge after the reset period

It is impossible to rearrange the wall charges by the reset waveform of the second subfield in the above-mentioned conventional method, so the addressing operation cannot be performed correctly in the addressing period

And, when applying image 3 When the reset waveform of the first subfield is shown, the brightness quality deteriorates and the reset operation time increases
