Patent ID: 8705133

Claim:
A display system for producing an image from image data for an image to be displayed, comprising: an illumination light valve comprising a first array of individually addressable pixel elements; an imaging light valve comprising a second array of individually addressable pixel elements; and projection optics; wherein the illumination light valve is dimensioned and configured to modulate an incident beam of light by the first pixel element array using the image data and to direct the modulated beam from the first pixel element array to form a blurred defocused image on the imaging light valve; wherein the imaging light valve is dimensioned and configured to modulate light of the blurred image by the second pixel element array using the image data; wherein the projection optics is dimensioned and configured to project the modulated light of the blurred defocused image from the second pixel element array onto a display surface; and wherein pixel elements of the illumination light valve are dimensioned and configured to provide illumination light for modulation by the imaging light valve having intensity variations, with highest and lowest intensities of the illumination light directed in general spatial correspondence onto pixel elements of the imaging light valve that image highest and lowest luminance parts of a scene of the image to be displayed.
