Patent ID: 7377652

Claim:
A display comprising: a first array of pixels configured to project individually-selectable amounts of light onto a second array of pixels; the second array of pixels configured to transmit individually-selectable amounts of light; and, a controller connected to the first and second arrays, the controller configured to drive the first array to project an approximation of an image specified by image data onto the second array, and to drive the second array to modulate the approximation of the image according to differences between characteristics of light incident on each individual pixel of the second array and desired characteristics of light specified by image data for a location of the image which corresponds to that individual pixel of the second array; wherein each pixel of the first array is configured to project light onto the second array in a manner characterized by a spread function having a full width at half-maximum in the range of 0.3×d 2 to 3×d 2 , where d 2 is a center-to-center inter-pixel spacing of pixels of the first array.
