Plasma display device and method of driving plasma display panel
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.
