There have been many reported problems associated with the response time of a liquid crystal display (LCD) display, typically termed as an afterimage seen especially when a motion picture video is being played. To reduce afterimage artifacts, we propose a new 'overdrive' method, named Response Time Acceleration (RTA), in this paper. The proposed new overdrive method effectively controls truncation errors, quantization errors, and fully non-accelerated errors present in conventional overdrive methods. Furthermore, video image quality is dramatically improved by utilizing only a few incremental gates.
