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.

摘要： An interlace-type PDP is driven by an improved driving method so as to achieve a greater operating margin, higher resolution, and higher brightness. The interlace-type PDP is driven using odd and even frames in such a manner that the cells are grouped into cell groups such that each cell group includes two or three cells which are adjacent in a direction crossing the electrode pairs, and the cells are driven in units of cell groups. The grouping of cells is performed differently for even and odd frames such that, in one type of frame, locations of two or three cells grouped into each group are shifted by one cell, in the direction crossing the electrode pairs, from the locations of cells grouped together in the other type of frame.
