Abstract
AbstractAuthors have been engaged in the development of a feed forward driving technique, as part of the overdrive technique to improve the response time of liquid crystal displays. They have developed, in particular, a compression feed forward driving system in which an image compression technique was applied, focusing on a method of reducing the frame memory necessary for the signal processing of overdrives. Further, they are now studying motion adaptive CODEC feed forward driving that reduces the amount of overdrive errors by adding a motion‐adaptive process to the image decoding section in cFFD. This paper discusses macFFD that does not use SDRAM as the overdrive for entry model LCD TVs. Setting the image compression ratio to 1/10 or so will enable the fabrication of frame memory for overdrive for SDTV using SRAM.
