Abstract
Plural subfields are provided in one single field period, where each subfield has an initialization period during which a gradient waveform voltage gently falling is applied to a scan electrode to generate initializing discharge in a discharge cell; a writing period during which a scan pulse voltage is applied to a scan electrode to generate writing discharge in a discharge cell; and a sustain period during which sustain discharge is generated in a discharge cell selected, by the number of times corresponding to a luminance weight. The lowest voltage of a falling gradient waveform voltage in a subfield with the smallest luminance weight is set so as to be lower than that with the largest luminance weight. A method of driving a plasma display panel is provided that generates stable writing discharge without increasing voltage required for generating writing discharge even for a large-screen, high-luminance panel.
