摘要： A wavelength selective reflection display (10) comprises a wavelength selective reflection medium (20) and a backing member (30) having a first, non-reflective optical state, and a second, reflective optical state. Both the wavelength selective reflection medium (20) and the backing member (30) are divided into pixels (40, 50, 60), and the backing member (30) is switchable between its first and second optical states on a pixel-by-pixel basis. The pixels of the backing member (30) are substantially aligned with those of the wavelength selective reflection medium (20).

摘要： 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.
