Abstract: A method of driving a display uses first and second illumination cycles of the display. In each cycle, a first set of pixels is illuminated with a first color and a second set of pixels is illuminated with a second color. The first and second colors of the two cycles together include at least three colors for forming an image. This method provides a sequential drive scheme, in that at least two cycles are used with different color properties. However, each cycle uses at least two different colors, so that each cycle is not a single color across the whole display area. In this way, the color sequence is alternated spatially as well as temporally.

Abstract: There is disclosed an optical beam deflection arrangement which may be used in an autostereoscopic display device. The arrangement comprises a substrate; a first layer, for example formed of an optically isotropic solid and having a curved surface facing towards the substrate; and a second layer, for example formed of a liquid crystal material confined between the substrate and the first layer. An interface between the first and second layers may, for example, define an array of parallel lenticulars. A refractive index of the second layer, for light of a predetermined polarization, maybe switchable between a first value matching the refractive index of the first layer and a second value different to the refractive index of the first layer, to thereby selectably provide a beam deflection function.
