Optical assembly, display system and manufacturing method

Abstract

The present disclosure relates to an optical assembly. The optical assembly comprises a light beam generator configured to emit a light-cone-distributed light beam group, a light conducting medium which is provided with a first surface and a second surface which are not parallel, a first beam combiner located on the first surface, and a second beam combiner located on the second surface, wherein the first beam combiner is configured to receive the light-cone-distributed light beam group and change the propagation direction of the light beam group, so as to make at least part of the light beam group propagated to the second beam combiner through the light conducting medium, and the second light beam combiner is configured to change the propagation direction of light beams entering the second light beam combiner from the first light beam combiner so as to make the light beams leave the second light beam combiner at different angles and continuously propagated, wherein the light beams of the same light-cone-distribution light beam group are converged at one point after leaving the second light beam combiner. According to the optical assembly, reverse projection compensation is performed on a projection area to form an image expanded in equal proportion, the image is coupled out and imaged on the retina, and therefore distortion-free large-view-field retina imaging is achieved.

Description

technical field [0001] The present disclosure generally relates to the field of optical display, and in particular to an optical component without imaging distortion based on trapezoidal back projection compensation, a display system and a manufacturing method. Background technique [0002] With the development of computer technology and display technology, virtual reality (Virtual Reality, VR) technology to experience the virtual world through computer simulation system, and augmented reality (Augmented Reality, AR) technology and hybrid technology to integrate display content into real environment background. Reality (Mixed Reality, MR) technology has developed rapidly. [0003] Near-eye VR, AR and MR display technologies that combine the aforementioned VR, AR and MR technologies with near-eye displays are important new display technologies that can bring unprecedented visual experience and human-computer interaction to people. Near-eye VR display mainly pursues immersive...

Problems solved by technology

The lens group of this solution is large in volume, and the half-transparent and half-mirror will attenuate the brightness of the ambient light by half. Realizing a compact display module with a large field of view that does not attenuate the ambient light is an important problem that needs to be solved urgently in retinal imaging technology.
