Aperture time sequence gating multiplexing optical waveguide display module

Abstract

The invention discloses an aperture time sequence gating multiplexing optical waveguide display module, which consists of a display device, a relay device, a time sequence aperture array, an optical waveguide device and other components, and is characterized in that the time sequence aperture array comprises more than one aperture and each aperture time sequence switch, and only one aperture is opened at one time point. The divergence degree of divergent light emitted by each pixel of the display device is reduced by the relay device, the size and the propagation vector direction of the divergent light are restrained by each aperture of the time sequence aperture array, and then the divergent light is guided by the optical waveguide device and enters an area where pupils of an observer are located in a narrow light beam or thin light beam mode in the respective corresponding vector direction. A monocular three-dimensional display capable of freely focusing is carried out on the basis of a monocular multi-image or / and Maxwellian view display mechanism, and the inherent focusing-convergence conflict problem of traditional three-dimensional display is solved. The optical waveguide display module for aperture time sequence gating multiplexing has a light and thin structure, and is suitable for portable display terminals such as head-mounted VR / AR and the like.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional display, and more particularly relates to an optical waveguide display module with aperture timing multiplexing. Background technique [0002] Compared with the traditional two-dimensional display, the three-dimensional display capable of presenting depth information has attracted much attention because the dimension of the displayed scene is consistent with the real space in which people live. However, most of the existing 3D displays are based on traditional stereoscopic technology for the presentation of 3D scenes, that is, by projecting a corresponding image to the observer's binoculars, and using binocular parallax to realize the presentation of depth information. During this process, each eye of the observer needs to focus on the display surface in order to see their corresponding images clearly, while the binocular gaze crosses the displayed scene out of the screen to trig...

Problems solved by technology

That is to say, the focus-convergence conflict of traditional stereoscopic technology is contrary to the physiological habits of the natural evolution of the human body, resulting in visual discomfort for the observer, which is a bottleneck problem hindering the popularization and application of 3D display technology
