Patent ID: 7719552

Claim:
A display device for displaying a three dimensional image such that different views are displayed according to the viewing angle, the display device including: a display panel ( 20 ) having a plurality of separately addressable pixels (p -7 . . . p 22 ) for displaying said image, the pixels being grouped such that different pixels in a group ( 21 ) along a first axis correspond to different views of the image, each pixel in a group being positioned relative to a respective discrete light source ( 22 ) and each pixel being separately controllable to vary an optical characteristic of each pixel to generate an image according to received image data; wherein the sizes of the pixels within a group vary as a function of the viewing angle of the pixels with respect to the respective light source along the first axis as: 0.5h[tan((n+1)Δφ eye )−tan((n−1)Δφ eye )] where n is the pixel position from the central pixel ( 0 , 15 ) of the group, h is the orthogonal separation of the light source to the plane of the group of pixels and Δφ eye is the angular separation between the left and right human eye, wherein Δφ eye approximates to arctan (s/d), where s is the average inter-ocular spacing between the left and right eyes and d is the viewing distance between the viewer and the display device; and polarizing elements of said display panel are oriented so as to minimize viewing angle dependence relative to a second axis, wherein said second axis is orthogonal to the first axis.
