  • Method and apparatus for driving plasma display panel
    Patent number: 7239295
    Abstract: 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 of generating optimal pattern of light emission and method of measuring contour noise and method of selecting gray scale for plasma display panel
    Patent number: 6693609
    Abstract: 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.
