Patent abstract
A time-sequential colour projector comprises a pixellated light valve (2), such as a liquid crystal device, and a plurality of light sources (30, 31, 32). The light sources (30, 31, 32) direct light on different sets of pixels of the light valve (2) via an optical system (1), such as a lens array, which focuses the light on pixels of the light valve (2). At least two of the light sources (30, 31, 32) are multiple colour light sources and the multiple colour light sources emit different colour components during each set of frames making up a complete image frame.
