Abstract
A method and apparatus for driving a plasma display panel in which pairs of sustain electrodes lines respectively including X-electrode lines and Y-electrode lines that are alternately arranged parallel with each other are disposed to be orthogonal to address electrode lines, and discharge cells are defined by intersections between the sustain electrodes and the address electrode lines. In the method, a unit frame as a display period is divided into a plurality of subfields to realize time-division grayscale display, and the individual subfields include a reset period, an address period, and a sustain period. The method includes maintaining the Y-electrode lines at a reference level during the reset period and the sustain period; and addressing the Y-electrode lines by biasing the Y-electrode lines to a first level and simultaneously, sequentially applying a scan signal of the reference level to the Y-electrode lines during the address period.
