Overdrive technique is mandatory for liquid crystal display (LCD) to mitigate the motion blur phenomenon. As the display resolution increases, the image data should be highly compressed to reduce the usages of frame memory and bandwidth. Since current high quality compression algorithms inevitably require large embedded memory (line buffer) and complex computations, a low complexity line-buffer-free edge-preserved compression algorithm is proposed in this paper to reserve the edge information for overdrive technique of LCD. Performance evaluations show that the proposed edge-preserved compression achieves above 20% PSNR improvements as compared to the conventional DPCM compression up to 6:1 compression ratio.
