Abstract
A display driving device includes an encoding unit and a frame memory. The encoding unit is configured to generate final mode information and a compressed bit stream based on a macro block and a first reference pixel, and generate a final bit stream using the final mode information and the compressed bit stream. The frame memory is configured to store and provide the stored final bit stream to a decoding unit. The final mode information includes mode information and a reconstruction reference value. The mode information indicates a selected mode from a plurality of modes, each of the plurality of modes indicating selection pixels and non-selection pixels in the macro block. The selection pixels are pixels in the macro block selected for undergoing a compression operation, the non-selection pixels are pixels not selected for undergoing the compression operation, and the reconstruction reference value indicates encoding information for the non-selection pixels.
