PROBLEM TO BE SOLVED: To provide an image compression method, an image enlarging method, and a dynamic image detecting method of a thin-film transistor liquid crystal display device. SOLUTION: A previous time frame and a present time frame which are two temporaly neighboring frame images are compressed by a cutoff technology and an evenly dividing technology. Whether the pixels of the present time frame image are of a dynamic image is detected by the two compressed data corresponding to the two frame images. When the pixels are of a dynamic image, the compressed pixel data of the previous time frame are enlarged, and an overdrive process is executed on the enlarged pixel data of the present time frame image and the original pixel data, and an overdrive output is created. When the pixels are not of a dynamic image, no overdrive process is executed. COPYRIGHT: (C)2006,JPO&NCIPI
