Patent ID: 8773407

Claim:
A driver for pixels of a display, the pixels arranged into a plurality of pixel blocks being in at least two rows and at least two columns, the driver comprising: a first converter receiving input image signals for a pixel block of the plurality of pixel blocks for a first frame, and generating compressed image signals by compressing the input image signals for the first frame based on both the input image signals for the first frame and compression reference image signals for the first frame; a frame memory storing the compressed image signals; and a second converter reading the compressed image signals from the frame memory, and restoring the compressed image signals based on the compression reference image signals to generate restoration image signals, wherein the compressed image signals are generated from the pixel block as a unit, wherein the compression reference image signal for compressing data for a first pixel in a first pixel block is the restoration image signal generated from performing a decompression on compressed data of a single second pixel in a neighboring second pixel block, and wherein the compression reference image signal for compressing data for a third pixel in the first pixel block is the restoration image signal generated from performing a decompression on compressed data of a single pixel in the first pixel block other than the third pixel.
