The invention provides a thin film with integrated grating and polarizer. The thin film with integrated grating and polarizer includes a grating film and a polarizer film. The polarizer film is prepared on a light incident side of the grating film and thereby the grating film and the polarizer film are disposed integrally. By the above method, the invention can reduce film thickness and simplify manufacturing process.

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 three-dimensional display apparatus comprises a display panel (display element) and a parallax barrier (optical element). The display panel displays a left-eye image and a right-eye image respectively in first subpixels and second subpixels. The parallax barrier transmits at least part of the left-eye image toward the left eye, and at least part of the right-eye image toward the right eye. A first certain number of the first subpixels and of the second subpixels are each successively arranged in each column. A region in which the first subpixels are arranged and a region in which the second subpixels are arranged are displaced from each other by a second certain number between two adjacent columns. The first certain number is greater than the second certain number and is not a multiple of the second certain number.
