A driver for pixels of a display, having pixels arranged into a plurality of pixel blocks including at least two pixels in a row and at least two pixels in a column is presented. The driver includes a first converter, a second converter, and a frame memory. The first converter receives input image signals for a pixel block of the plurality of pixel blocks and generates compressed image signals by compressing the input image signals based on compression reference image signals. The frame memory stores the compressed image signals. The second converter reads the compressed image signals from the frame memory, and restores the compressed image signals based on compression reference image signals to generate restoration image signals. A compression reference image signal for a first pixel of the pixel block is the restoration image signal for a second pixel of a neighboring pixel block. Compression reference image signals for the remaining pixels in the pixel block are restoration image signals for different pixels in the pixel block.
