The present invention provides a glasses-free optical 3D stereoscopic display screen comprising an optical element assembly wherein the optical element assembly utilizes refraction effects to generate one of the following viewing modes: positive parallax hyperstereo viewing mode, positive parallax hypostereo viewing mode, negative parallax hyperstereo viewing mode, and negative parallax hypostereo viewing mode, which can causes a viewer to perceive 3D stereoscopic vision of a 2D image content shown on a conventional display screen, such as movie, TV, computer, tablet, gaming console, billboard, mobile device, etc. screens.

Systems and methods are described for providing a 3D display, such as a light-field display. In some embodiments, a display device includes a light-emitting layer comprising an addressable array of light-emitting elements. An optical layer overlays the light-emitting layer. The optical layer includes a plurality of distributed lenses. In some embodiments, the distributed lenses include non-contiguous lens regions. In some embodiments, distributed lens regions with different optical centers are interlaced with one another. A spatial light modulator is operative to provide control over which lens regions transmit light from the light-emitting layer outside the display device. In some embodiments, the use of interlaced and/or non-contiguous distributed lenses provides improved display resolution with a reduction in diffraction effects.

Among the sub-pixels located to correspond to each of the optical elements, at least two sub-pixels, adjacently arranged, display the same view image.

A device for MR/VR systems that includes a two-dimensional array of cameras that capture images of respective portions of a scene. The cameras are positioned along a spherical surface so that the cameras have adjacent fields of view. The entrance pupils of the cameras are positioned at or near the user's eye while the cameras also form optimized images at the sensor. Methods for reducing the number of cameras in an array, as well as methods for reducing the number of pixels read from the array and processed by the pipeline, are also described.

A display device includes: a first substrate and a second substrate; and a plurality of pixel portions provided between the first substrate and the second substrate, wherein the second substrate includes a plurality of lenticular lens portions, and each of the plurality of lenticular lens portions includes: a curved portion corresponding to a first pixel portion among the plurality of pixel portions; and a plane portion corresponding to a second pixel portion that neighbors the first pixel portion among the plurality of pixel portions.

A lenticular display device that is effective in increasing both perceived angular resolution and spatial resolution. These desirable results are achieved by modifying the lenslet array to better match the content of a given light field. An optimization algorithm or method (which may be implemented with software run on a computing device) is provided that analyzes an input light field and computes an optimal lenslet size, shape, and arrangement of sets of lenslets across the width of the array to better (or even best) match the input light field given a set of output parameters. The resulting lenticular display device (or print) shows higher detail and smoother motion parallax compared with fixed-size lens arrays. The usefulness of these content-adaptive lenticular prints has been demonstrated or proven using rendered simulations, by generating 3D-printed lens arrays according to the present description, and with user studies.

A three-dimensional (3D) image display apparatus includes a display panel and a 3D image optical structure. The display panel has pixels arranged in an array and the pixels have a first region and a second region disposed adjacent to each other. The 3D image optical structure includes a plurality of first optical units disposed along a first direction. Each first optical unit has at least one first portion corresponding to the first region and at least one second portion corresponding to the second region. The first portion has a first curvature radius and a plurality of corresponding first circle centers, and the second portion has a second curvature radius and a plurality of corresponding second circle centers. The first curvature radius is different from the second curvature radius, and the first circle centers are not overlapped with the second circle centers in the vertical projection direction.
