Verfahren und Vorrichtung zur Ansteuerung einer Plasmaanzeige

摘要

Disclosed herein is a method and apparatus for driving a plasma display panel in which signal distortion can be minimized while reducing contour noise. According to the present invention, the method of driving the plasma display panel includes the steps of performing a first inverse gamma correction operation on externally inputted video data, performing a confined error diffusion operation on the first inverse gamma corrected video data within a range of a dither mask pattern of an upper gray scale, dithering the confined error diffused video data by using a plurality of dither mask patterns which are separated every gray scale and every frame, performing a second inverse gamma correction operation on the dithered video data, and mapping the second inverse gamma corrected video data to a sub-field pattern in which one frame includes one or more selective writing sub-fields and one or more selective erasing sub-fields.
