Abstract
The invention provides an integrated imaging three-dimensional (3D) display device based on a gradually-variable-aperture pinhole array. The integrated imaging 3D display device comprises a 2D display device and the gradually-variable-aperture pinhole array which is placed in front of the 2D display device. In the gradually-variable-aperture pinhole array, the horizontal aperture widths of pinholes in any column are the same, the vertical aperture widths of pinholes in any row are the same, and the aperture widths of the pinholes of the gradually-variable-aperture pinhole array become greater gradually from the edges to the center of the array. The horizontal viewing angle of the integrated imaging 3D display device is only related to the horizontal aperture widths of the pin holes in a first column of the gradually-variable-aperture pinhole array. However, the optical efficiency is related to the horizontal aperture widths and the vertical aperture widths of all the pinholes of the gradually-variable-aperture pinhole array. Due to the fact that the aperture widths of the pinholes of the gradually-variable-aperture pinhole array become greater gradually from the edges to the center of the array, on the premise that the horizontal viewing angle is not reduced, high-brightness integrated imaging 3D displaying is realized.
