Abstract

See full text

An illuminator for a display panel includes a slab of transparent material for propagating illuminating light between outer surfaces of the slab, an out-coupling grating supported by the slab for out-coupling portions of the illuminating light along one of the outer surfaces of the slab, and an amplitude and/or phase mask for forming an array of light spots from the out-coupled illuminating light portions downstream of the focusing element for illuminating pixels of the display panel. The array of light spots may be repeated at a distance from the mask due to Talbot effect. A beam redirecting element such as a tiltable reflector and/or a steering surface may be provided to shift the lateral location of the illuminating light spots.
