ILLUMINATION SYSTEM FOR DISPLAYING IMAGES WITHOUT COLOUR BREAK

摘要

The invention concerns an image display system comprising: a light source (1) emitting an illuminating laser beam, a spatial light modulator (2) controlled by control video signals corresponding to a succession of image frames; a matrix filter (3) consisting of an array of different elementary colour filters, illuminated by said illuminating beam and transmitting a spatially colour-filtered beam to the spatial light modulator (2), an image of said filter being produced on an input surface of the spatial light modulator; means for displacing the filter image (3) on the input of the spatial light modulator (2); and a control device for controlling at least one sequence of displacements of the filter image upon each image frame display.
