Abstract:
A display system comprising:a light source for producing a beam of white light along a first light path; a filter wheel on said first light path for filtering said beam of white light, said filter wheel having at least one set of primary colored filters thereon; a motor connected to said filter wheel for spinning said filter wheel at a nominal speed; a spatial light modulator on said first light path for receiving said filtered beam of light traveling along said first path and selectively modulating said filtered beam of light traveling along said first path to form an image; and a controller receiving an input video signal at a video frame rate and providing image data decoded from said input video signal to said spatial light modulator, said input video signal having one of at least two native frame rates, said controller detecting said native frame rate and converting said input video signal to said native frame rate when said native frame rate is not equal to said video frame rate and displaying said decoded image data at said native frame rate.
