A method of driving an AC type plasma display (AC PDP) using a phase difference method and a circuit therefor and a PDP panel

摘要

The present invention uses a phase difference between a data input pulse and a scan pulse in an AC PDP having a three-electrode surface discharge structure, so that the complexity of the driving apparatus is not increased as compared with the conventional driving method The present invention relates to a method of driving an AC PDP, a circuit therefor, and a PDP panel.;For this purpose, in the present invention, in a three-electrode surface discharge AC PDP in which each cell is composed of two row electrodes and one column electrode, the row electrodes are divided into the upper and lower groups of the screen and the driving pulses The phase difference is shifted by 1/2 cycle of the sustain pulse so that the time required for the full screen scan is reduced to 1/2 and the data pulses are applied to the column electrodes, The time required for the full-screen scanning is set to 1/2 by setting the phase difference between the upper and lower scan pulses of the screen by 1/2 cycle of the sustain pulse, by separating the electrodes and the scan electrodes to which the sustain and scan and erase pulses are applied together. 2, respectively.
