Abstract:
An apparatus for driving an interlaced plasma display panel (PDP), including a delay device, an image upper and lower edge detection device, an image border processing device, an image processing and analog control loop. The delay device receives an image signal, delays the image signal for two fields and outputs the delayed image signal. The image upper and lower edge detection device receives and analyzes the image signal, outputs the image upper and lower edge positions, saves and provides the odd field upper and lower edge data of the image signal. The image border processing device outputs the image signal after border processing according to the delayed image signal, the image upper and lower edge positions, the odd field upper and lower data. The image processing and analog control loop outputs a driving signal according to the image signal after border processing and the image upper and lower edge positions.

Abstract:
A driving device of a plasma display panel including a gray level arrangement unit, a still frame detection unit and a gray level arrangement controller is provided. The gray level arrangement unit receives image data and arranges the image data according to different gray level arrangement rules. The still frame detection unit detects whether the image data is a still frame. The gray level arrangement controller is electrically connected to the still frame detection unit and the gray level arrangement unit, and controls the gray level arrangement unit to output the image data with different gray level arrangements according to whether the image data is a still frame or not. A driving method of a plasma display panel is also provided.
Abstract:
A driving method and a driving circuit of a plasma display panel are provided. The driving circuit comprises a calculating unit, a gain unit, and a control unit, wherein the calculating unit is used for receiving an image signal to output a first display loading corresponding to the image signal. The gain unit is used for receiving the first display loading and by multiplying the first display loading with a gain constant, and then a second display loading is outputted. Furthermore, the control unit is used for receiving the second display loading to correspondingly output a sustain frequency. The power consumption of the plasma display panel is conformed to a rated value by driving with the sustain frequency.

Abstract:
A front panel structure of Plasma Display Panel (PDP) is disclosed sequentially comprising a first electrode, a second electrode and a third electrode, wherein the second electrode has transparent electrodes located on both top and bottom sides of a bus electrode. A first discharge center is formed between a transparent electrode of the first electrode and one transparent electrode of the second electrode. A second discharge center is formed between the other transparent electrode of the second electrode and a transparent electrode of the third electrode. Therefore, an emitting cell of PDP has two discharge centers. To make the discharge more stable, we choose the first electrode and the third electrode to become the scan electrodes, or to form a thicker dielectric layer or discharge deactivation film below the second bus electrode as a scan electrode.
