Problems solved by technology

Therefore, the X and Y electrode drive circuits are not impedance-matched, and the waveforms alternately applied to the X and Y electrodes during the sustain discharge cycle are deformed, and bad discharges are generated
[0019] Also, when the first (or initial) sustain discharge pulse is applied after the address period of a conventional PDP, a problematic (or weak) discharge may occur due to the generation of insufficient priming particles

Abstract

A method for driving a plasma display panel (PDP) and for safely erasing wall charges in an erase period. The PDP includes a middle (M) electrode formed between an X electrode and a Y electrode. A sustain discharge pulse voltage is periodically applied to the X electrode and the Y electrode in a pulse train fashion. In addition, a reset waveform, a scan pulse voltage, and a sustain discharge voltage are applied to the middle electrode. Moreover, to prevent a strong discharge, an erase waveform is applied to the M electrode in the erase period while the X and Y electrodes are biased with the same voltage level. Alternatively, to prevent a strong discharge, an erase waveform (a gradually rising waveform) is applied to the X electrode in the erase period while the M and Y electrodes are biased with the same voltage level (a ground voltage).

Description

technical field [0001] The present application relates to a driving method of a plasma display panel (PDP). Background technique [0002] In recent years, liquid crystal displays (LCDs), field emission displays (FEDs), and plasma displays have been actively researched. Among these flat panel devices, the plasma display has better brightness and luminous efficiency, and also has a wider viewing angle than other types of flat panel devices. Therefore, plasma displays have attracted attention as a substitute for conventional cathode ray tubes (CRTs) in large displays larger than 40 inches. [0003] A plasma display is a flat panel display that uses plasma generated by a gas discharge process to display characters or images. Depending on its size, a plasma display may include tens to millions of pixels arranged thereon in a matrix. Plasma displays can be classified into direct current (DC) plasma displays and alternating current (AC) plasma displays according to supplied driv...
