Abstract
Video displays using relatively low frame rates of about 10 to about 20 frames per second, but having acceptable video quality are described. The displays may use bistable media, and may be driven such that the medium, when driven, changes its optical properties continuously during the driving of each frame. The displays may use an electro-optic medium such that the frame period is from about 50 to about 200 per cent of the switching time of the electro-optic medium at the driving voltage used.
