Abstract:
1. A projection system comprising: a plurality of controllable emitters, said controllable emitters capable of being locally dimmed according to control signals, each said emitter providing light for a light path; a plurality of first optical elements, each said first optical element receiving light from one of said emitters; one or more controllable modulators receiving light from said plurality of first optical elements; a plurality of conduits, each said conduit disposed over a portion of said one or more controllable modulators; a plurality of second optical elements, each of said second optical elements receiving light from at least one of said plurality of conduits; a controller, said controller sending control signals to said controllable emitters and said one or more controllable modulators, said control signals applied according to image data to be rendered upon a screen by projected light from said plurality of second optical elements; and further wherein said one or more controllable modulators are disposed to transmit light to affect a plurality of overlapping areas of illumination upon a projection screen; and wherein said one or more controllable modulators are organized into groups, and further wherein a group of said groups of controllable modulators provides illumination for one of said second optical elements; and wherein illumination from the group of said groups of controllable modulators generates a projected image with imaging gaps.
