Abstract
Display standards in common use for the display of computer or television images on high resolution displays, commonly assume that the output image will be displayed on a output device having a high refresh rate. A high refresh rate is normally required to avoid the viewer observing flicker, stilted motion or other visual artifacts if a lower refresh rate were used. It is difficult to drive a high resolution Ferroelectric Liquid Crystal Display at a high refresh rate. The subject apparatus is provided for using the memory function characteristics of such a display and driving such a display at a slower refresh rate while still maintaining the appearance of a device having a higher refresh rate by refreshing those portions of the screen where motion has been detected at a high rate and only occasionally refreshing the whole screen.
