Abstract
A plasma display apparatus which is capable of reducing power consumption and achieving a high definition display. A plasma display panel has a plurality of first row electrodes and second row electrodes extending in a horizontal direction and formed in alternation, a discharge space filled with a discharge gas, and a plurality of column electrodes formed opposite to and extending in a direction perpendicular to the first row electrodes and the second row electrodes through the discharge space. The plasma display panel also has discharge cells corresponding to pixels, formed at respective intersections of the first row electrodes and second row electrodes with the column electrodes, and a spacing between each of the first row electrodes and each of the second row electrode is conformed to a display line on the screen. A reset discharge is caused to occur for forming wall charges in all of the discharge cells; a selective erasure discharge for selectively erasing the wall charges formed in the respective discharge cells in accordance with an input video signal; and a sustaining discharge for forcing only those discharge cells formed with the wall charges to repeatedly emit light. According to a second aspect of the present invention, a plasma display apparatus comprises a capacitor, a first switching current path for selectively discharging a charge accumulated on the capacitor to supply the charge to a power supply line, a second switching current path for selectively applying a power supply potential to the power supply line, a third switching current path for selectively charging the capacitor with charges accumulated on column electrodes through the power supply line, and a pixel data pulse generator circuit for connecting the power supply line to the column electrodes for a predetermined period of time in response to the input video signal to generate pixel data pulses corresponding to the input video signal and applying the pixel data pulses onto the column electrodes.
