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.
