Controller driver, liquid crystal display apparatus using the same, and liquid crystal driving method

摘要

A controller driver includes a first compressor for compressing received image data to generate first compressed image data, a second compressor to generate second compressed image data, and an image memory capable of storing the second compressed image data of at least one frame. It also includes an overdrive processing unit for generating corrected image data where a tone value of the received image data is corrected from the first compressed image data or its expanded data and second compressed image data of one frame previous to the first compressed image data or its expanded data. The compression processing performed in the first compressor is the same as compression processing performed in the second compressor in compressing image data of one frame previous to the received image data.
