Abstract:
1. A plasma display apparatus in which a plasma display panel on which a display cell having a discharge space is formed in each of crossing portions of a plurality of row electrode pairs and a plurality of column electrodes extending in the direction which crosses each of said row electrode pairs is driven for each of a plurality of subfields having different luminance weights, comprising: a magnesium oxide layer containing magnesium oxide crystals which are formed in each of said display cells, and have a characteristic of performing a cathode luminescence light emission having a peak in a wavelength range of 200 to 300 nm when irradiated by an electron beam; an addressing component for setting each of said display cells into a light-on cell state or a light-off cell state by selectively causing a selective discharge in said discharge space of each of said display cells by sequentially applying a scanning pulse to one row electrode of each of said row electrode pairs and applying a data pulse corresponding to an input video signal to each of said column electrodes; and a sustaining component for causing a sustaining discharge in said display cell which has been set into said light-on cell state by applying sustaining pulses to each of said row electrode pairs by the number of times corresponding to said luminance weight of each of said subfields, wherein said sustaining component applies said sustaining pulse to said row electrode pair only once in said subfield having the minimum luminance weight among said subfields.
