摘要： The present invention provides a plasma display device including: a plurality of scan electrodes sequentially scanned to be impressed with a scan pulse; an address electrode that is impressed with an address pulse corresponding to the scan pulse, for selection of a display pixel; a scan driving circuit generating the scan pulse; and an address driving circuit generating the address pulse. The address pulse rises in n stages (n is an integer equal to or larger than 2), and a period in a period during which the address pulse rises from a lowest voltage to a highest voltage overlaps a scan pulse immediately prior to the scan pulse corresponding to the address pulse.

摘要： A method and an apparatus for driving a plasma display in which supply of a driving waveform to the non-lighting display line of a plasma display screen is stopped while preventing level difference in luminance or instability of operational margin incident to stoppage of driving waveform supply. In the inventive plasma display, a sustain waveform is created and supplied to each display line of the plasma display, and supply of the sustain waveform is stopped for such a display line as no cell is lighted at all in a unit of sub-field thus quickening the clamp period of sustain waveform by using an inductance having an increased L value and shortening the sustain cycle.

摘要： In a long-gap discharge using a trigger discharge in a display cell of a PDP having three electrodes (X, Y, A), a technology capable of stably generating the trigger discharge with low power consumption by using a float electrode is provided. In a dielectric layer of the PDP, a long gap is formed between first and second display electrodes, first and second float electrodes which are capacitive-coupled to the first and second display electrodes are formed, and a short gap is formed between the first and second float electrodes. A sustain pulse is applied to the first and second display electrodes, thereby generating a small trigger discharge in the short gap. Subsequently to this discharge, a main discharge at the long gap is generated. Electrodes and capacitances are structured so that the main discharge has an intensity equal to or smaller than one-fifth of an intensity of the trigger discharge.

摘要： A plasma display panel has a front substrate (3) and a back substrate (2) arranged opposed to each other through a discharge space (4). On the back substrate, a fluorescent layer (5) is formed. On the front substrate, display electrodes are formed extending in a horizontal direction, a discharge cell area is demarcated corresponding to the display electrodes, and a plurality of shielding films (13) extending in the horizontal direction are moreover formed at each position which is among the display electrodes and within the discharge cell area. When the distance between the shielding films and the fluorescent layer is set to be D, the width L of a shielding film and the distance S between the shielding films satisfy 0.58≦L≦D and D≦S≦1.73D. This reduces the reflectance ratio of outdoor daylight to improve lighted room contrast.
