Abstract

See full text

The present invention relates to an apparatus and method for driving a PDP (plasma display panel). An image signal processor of the apparatus performs gamma correction and error diffusion processes of input image signals. A quantization error compensator compensates quantization errors with respect to an automatic power control (APC) level of image data output from the image signal processor. An error diffuser sets part of the image data output from the quantization error compensator as display errors and diffuses the display errors to peripheral pixels. A memory control and address driver generates sub-field and address data corresponding to image data that have undergone error diffusion by the error diffuser, and applies the data to the PDP. An APC and sustain/scan pulse generator generates a sub-field arrangement structure according to the APC level, generates control signals based on the generated sub-field arrangement, and applies the control signals to the PDP.
