Abstract:
1. A plasma display device comprising: a plasma display panel including a plurality of row electrode pairs extending in a row direction and a plurality of column electrodes extending in a column direction perpendicularly to the row direction, with a plurality of display cells each having a discharge space being formed at each of intersections of the plurality of row electrode pairs with the plurality of column electrodes; a magnesium oxide layer having an magnesium oxide crystal formed in each said display cell and excited by an electron beam irradiated thereto to emit cathode luminescence light having a peak in a wavelength range of 200 to 300 nm; resetting means for applying a reset pulse to one or two electrodes in each said row electrode pair to produce reset discharge in said discharge space of each said display cell to initialize each said display cell; addressing means for sequentially applying a scanning pulse to one electrode in each said row electrode pair, and applying a data pulse corresponding to an input video signal to each said column electrode to selectively produce a selective discharge in said display space in each said display cell so as to set each said display cell to a lit state or an unlit state; and sustaining means for applying a sustain pulse to one or two electrodes in each said row electrode pair to produce a sustain discharge in said discharge space in each said display cell which has been set to the lit state, wherein part of said reset pulse has a voltage value which slowly changes over time.
