摘要： A method for driving a plasma display panel is provided in which wasteful power consumption is reduced and light emission efficiency is improved when the number of cells to be lighted is relatively small. The method includes classifying a display ratio into plural group ranges, selecting a suitable display pulse waveform for each group range, detecting the display ratio of an object to be displayed in a real display, and plural types of display pulses having different waveforms are used differently in accordance with the result of the detection. The display ratio means a ratio of the number of cells to be lighted to the number of cells of the screen.

摘要： There is provided a plasma display device capable of high luminous efficacy and stable driving for displaying images at various image display load factors. The plasma display device performs the sustain discharge for a light-emission display, and is configured to apply a sustain pulse voltage between a sustain electrode pair in a respective one of the plural discharge cells to generate a sustain discharge in a respective one of the following operating modes selected based upon use of the plasma display device: (a) generating a pre-discharge and then a main discharge; (b) generating a main discharge without a pre-discharge preceding the main discharge; and (c) switching between the mode (a) and the mode (b). The sustain voltage waveforms are used which compensate for an increase in voltage drop due to an increase in discharge current when the image display load factor is excessively increased.

摘要： In a conventional method of driving a plasma display panel, for example, an auxiliary discharge is executed between an A electrode and a Y electrode to improve light-emission efficiency of a display discharge. However, since a phosphor layer is present between the A electrode and the Y electrode, the phosphor layer is exposed to a discharge, whereby there is a problem that its characteristic deteriorates. A method of driving a plasma display panel having a structure, in which at least three display electrodes X, Y, and Z used for a display discharge are provided to a display cell and no phosphor layer is formed between said display electrodes and a discharge space, the method comprising the steps of: varying a potential of at least one display electrode Z of said display electrodes during said display discharge; and making a potential of said at least one display electrode Z at a time of starting said display discharge different from that at a time of ending said display discharge.
