Abstract

The invention involves a method to maintain the discharge waveform for the double-discharge plasma center display. The plasma display panel includes the first electrode, the second electrode and the third electrode. The method to maintain discharge waveforms includes the following steps: provide a voltage to the first electrode, the voltage wave features include a first maintain voltage and a second maintain voltage; provide a voltage to the third electrode, the voltage wave features include a third voltage and a fourth voltage; and the second electrode discharge with the first electrode and the third electrode to form two discharge centers.

Description

technical field [0001] The invention relates to a plasma display panel and a method for maintaining discharge waveforms, in particular to a plasma display panel with double discharge centers and a method for maintaining discharge waveforms. Background technique [0002] A plasma display panel (PDP) is a panel display device that uses internal gas discharge phenomena to display dynamic or static images. According to the number of electrodes per pixel (pixel), the current mainstream of plasma display panels is three polar AC type, such as figure 1 As shown, it is composed of two front and rear substrates plated with conductive electrodes arranged in parallel. [0003] On the front substrate 100 of the plasma display panel, sustain electrodes (sustain electrodes, also known as X electrodes) 110 and scan electrodes (scan electrodes, also known as Y electrodes) 120 are arranged in parallel, and the material of the electrodes is transparent conductive material indium oxide Tin (...
