A method and apparatus for driving a plasma display panel that is adaptive for improving a capability of gray scale expression as well as a picture quality. In the method and apparatus, an average brightness of an image is detected. A gray level number of the current image is adjusted in accordance with said average brightness of said image using a pre-stored reference gray level number.

Method and apparatus for driving plasma display panel

There is disclosed a method and apparatus of driving a plasma display panel that is adaptive for expressing linear gray levels by way of preventing a gray level inversion. A driving method of a plasma display panel according to an embodiment of the present invention includes allocating a first brightness weight to the sub-fields; and setting a second brightness weight by way of subtracting the amount of light generated during the address period from the first brightness weight.

Method and apparatus of driving plasma display panel

An optimal light-emission pattern generation method for a plasma display panel according to an embodiment of the present invention includes steps of determining a plurality of light-emission patterns with respect to an arbitrary gray level; calculating a contour noise degree between a contour noise free gray level being set in advance and the light-emission patterns given to each gray level in plurality; and selecting a light-emission pattern whose contour noise degree is minimal as a light-emission pattern with respect to an arbitrary gray level.

Method of generating optimal pattern of light emission and method of measuring contour noise and method of selecting gray scale for plasma display panel
