摘要： In the reset step for initializing an amount of wall charge in each of the plurality of discharge cells that define each of the picture elements in a plasma display panel, the number of reset discharges that are caused to occur in the discharge cells that handle the emission of light of at least one color within the picture element is greater than the number of reset discharges that are caused to occur in the discharge cells that handle the emission of light of the other color(s). The plasma display panel drive method provides a stable electrical discharge effect while increasing contrast.

摘要： A plasma display panel and a drive method therefor, which can enhance a representation capability when displaying a dark image. The plasma display panel includes fluorophor layers containing magnesium oxide. The drive method includes a reset step to initialize all the pixel cells into states of one of a light-up mode and a light-off mode, and an address step in which the pixel cells are caused to perform address discharges selectively in accordance with pixel data, which are successively executed in each of a head subfield and a second subfield within a one-field display period. In reset step, a voltage that sets row electrodes on one side, in the row electrode pairs as an anode and sets the column electrodes set as a cathode is applied between the row electrodes on the one side and the column electrodes.

摘要： The object is to provide a method for driving a plasma display panel, the method being capable of providing improved display quality. A display cell of the plasma display panel is reset to a light-emitting cell state (or a non-light-emitting cell state) only in the head subfield during the display period of one field. Then, in each subfield, executed is a data write process for applying successively a scanning pulse, for generating a selective erase discharge, to each of the row electrodes in order to change selectively each of the display cells from the light-emitting cell state (non-light-emitting cell state) to the non-light-emitting cell state (light-emitting cell state) in accordance with an input video signal. Also executed in each subfield is a light emission sustain process for applying a train of sustain pulses to each of the row electrodes in conjunction with the scanning pulse, the train of sustain pulses generating a sustain discharge to allow only a display cell in the light-emitting cell state to emit light for the number of times corresponding to a weight of each of the subfields.

摘要： A plasma display device and a method of driving a plasma display panel are provided for improving the contrast without degrading the image quality. Each of display cells formed on the plasma display panel has a magnesium oxide layer containing magnesium oxide crystals. The magnesium oxide crystals are excited by an electron beam irradiated thereto and emit cathode luminescence light having a peak in a wavelength range of 200 to 300 nm. In order to trigger a rest discharge in all the display cells, each row electrode pair of the plasma display panel is applied with a reset pulse which has a particular pulse waveform. The voltage value of this reset pulse slowly changes over time to reach a peak voltage value.
