Problems solved by technology

However, there are three obvious shortcomings in the existing integrated imaging dual-view 3D display: 1. The two 3D viewing areas are separated, and the viewer needs to move the viewing position to see another 3D picture; 2. The resolution is not uniform; 3. low optical efficiency
Therefore, the application of integrated imaging dual-view 3D display in home entertainment equipment and medical equipment is limited

Abstract

The invention discloses a high optical efficiency and uniform resolution dual-view 3D display device and method, wherein first polarization units and second polarization units are alternately arrangedin the horizontal and vertical directions, and first image elements and second image elements respectively correspond to and align with the first polarization units and the second polarization units,in the premise of not increasing the 3D image resolution, the resolution of the 3D image is more uniform, and the display effect is improved; different 3D images can be switched by wearing differentpolarization glasses without moving the viewing spots; the aperture width of the graded aperture pinhole array gradually increases from the edge to the center, the optical efficiency is increased, andthe brightness of the 3D image is improved.

Description

technical field [0001] The present invention relates to dual-view 3D display, and more specifically, the present invention relates to a dual-view 3D display device and method with high optical efficiency and uniform resolution. Background technique [0002] Integrated imaging dual-view 3D display is the fusion of dual-view display technology and integrated imaging 3D display technology. It can make viewers see different 3D images in different viewing directions. However, there are three obvious shortcomings in the existing integrated imaging dual-view 3D display: 1. The two 3D viewing areas are separated, and the viewer needs to move the viewing position to see another 3D picture; 2. The resolution is not uniform; 3. Optical efficiency is low. Therefore, the application of integrated imaging dual-view 3D display in home entertainment equipment and medical equipment is limited. Contents of the invention [0003] The object of the present invention is to overcome the abov...
