Image Compression Circuit, Display System Including the Same, and Method of Operating the Display System

摘要

An image compression circuit includes an encoder configured to compress a current frame and to output current frame compressed data and a current frame bitstream; a decoder configured to decode the previous frame bitstream and to output previous frame compressed data; a frame memory controller configured to write the current frame bitstream to a frame memory and simultaneously read a previous frame bitstream from the frame memory; a dynamic capacitance compensation controller configured to output a previous frame reference value based on the current frame, the current frame compressed data, and the previous frame compressed data; and an overdrive circuit configured to generate a current overdriven frame including an overdrive pixel value for a current pixel based on a pixel value of the current pixel in the current frame and the previous frame reference value.
