Supersampled 3D display with improved angular resolution

A three-dimensional (3D) electronic display, comprising:

• a driver configured to drive pixels of the 3D electronic display with angular combinations of different 3D views of a 3D image and products of intermediate 3D views of the 3D image and associated weights, wherein the intermediate 3D views are between the different 3D views;
• wherein, when viewing the 3D electronic display along a principal angular direction associated with a 3D view in the different 3D views, a viewer sees the 3D view and, when viewing the 3D electronic display along an intermediate principal angular direction associated with an intermediate 3D view in the intermediate 3D views, the viewer sees the intermediate 3D view;
• a plate light guide configured to guide collimated light as a guided light beam at a non-zero propagation angle;
• and
• an array of multibeam diffraction gratings at a surface of the plate light guide, a multibeam diffraction grating of the array being configured to diffractively couple out a portion of the guided light beam as a plurality of coupled-out light beams having different principal angular directions corresponding to directions of the different 3D views of the 3D electronic display.

A method of providing supersampling, the method comprising:

• driving an adjacent pair of pixels in a three-dimensional (3D) electronic display based on angular combinations, wherein a pixel in the pair of pixels is driven by an angular combination in the angular combinations of a pixel in a 3D view of a 3D image and at least one product of a pixel in an intermediate 3D view and an associated weight,
• wherein 3D views applied to the pair of pixels have different associated angular ranges with different principal angular directions,
• wherein the intermediate 3D view has an associated intermediate angular range with an intermediate principal angular direction that is between the principal angular directions;
• and
• wherein when viewing the 3D electronic display along a principal angular direction in the principal directions of the 3D view, a viewer sees the 3D view, and when viewing the 3D electronic display along the intermediate principal angular direction, the viewer sees the intermediate 3D view.

A computer-program product for use in conjunction with a driver circuit, the computer-program product comprising a non-transitory computer-readable storage medium and a computer-program mechanism embedded therein to provide super resolution, the computer-program mechanism including:
