  • Patent number: 7474279
    Abstract: The present invention relates to a plasma display panel, and more particularly, to a method and apparatus for driving a plasma display panel. According to a first embodiment of the present invention, there is provided a method for driving a PDP including the steps of dividing two frame data items into three frame data items; and providing the divided frame data items to the PDP. According to a first embodiment of the present invention, there is provided a method for driving a PDP including the steps of dividing two frame data items into three frame data items; and providing the divided frame data items to the PDP. The method and apparatus for driving a PDP according to the present invention can reduce large area flicker and dynamic false contour noise in a high-resolution PDP.

  • Patent number: 7081906
    Abstract: The present invention relates to a driving device for a flat panel display and driving method of, capable of enhancing an image quality. In the present invention, a gray level of an original image is rearranged using the minimal distribution lower and upper gray levels determined using a histogram. The present invention provides the means to solve an excessive change of color that can be generated when rearranging the gray level of the original image, an image display deterioration due to the low gray level area and a saturation of the high gray level area.

  • Patent number: 6621230
    Abstract: The present invention relates to a plasma display panel, and more particularly, to a method for operating a plasma display panel (PDP), in which a pulse applied to an electrode in the PDP is controlled according to a gray scale of a picture to be displayed. The method for operating a PDP having three electrodes, the PDP for displaying one frame which includes a plurality of sub-fields each having a reset period, an addressing period, and a sustain period in view of time, the method including the steps of applying a fixed number of pulses in a fixed frequency in each period for displaying an image of a particular grey scale, and adjusting a number of pulses and/or a frequency applied in each period for displaying an image having a grey scale different from the particular grey scale.

  • Patent number: 6433763
    Abstract: A plasma display panel drive art capable of restraining a contour noise in a picture displayed on a PDP and reducing a maximum power consumption. The drive art allows one frame to be consisted of a plurality of sub fields each having a different weighting value for brightness so as to display a video signal of gray scale. The plurality of the sub fields are differently arranged along with a distribution of logical values in the video data for one frame, thereby dividing the one frame into a display interval and a non-display interval. Also, the plurality of the sub fields are equal to sub fields without a sub field having a least weighting value for the brightness.

  • Patent number: 6320313
    Abstract: A plasma display panel with a bilateral display function that is adaptive for displaying a picture in two directions and a driving apparatus thereof are disclosed. In the plasma display panel, a first plasma display panel displays a picture by a discharge. A second plasma display panel is installed such that its display face is opposed to that of the first plasma display panel. An optical shutter is installed between the first and second plasma display panels to transmit or shut off lights incident thereto from the first and second plasma display panels.
