Novel augmented reality near-to-eye display device and augmented reality display equipment

Abstract

The invention relates to a novel augmented reality near-to-eye display device and augmented reality display equipment. The augmented reality near-to-eye display device comprises a display source, a collimation system and an X-type polarization array optical waveguide lens; the display source is arranged on a main optical axis of the collimation system and used for loading and outputting an image, the display source comprises a red light Micro-LED micro-display, a green light Micro-LED micro-display, a blue light Micro-LED micro-display and a light combination prism, and the light combination prism is used for combining emergent light of the red light Micro-LED micro-display, emergent light of the green light Micro-LED micro-display and emergent light of the blue light Micro-LED micro-display into one beam; the collimation system is positioned on the light emitting surface of the display source and is used for collimating and correcting an image output by the display source and then enabling the image to enter the ''X-type'' polarization array optical waveguide lens; and the ''X-shaped'' polarization array optical waveguide lens is arranged on an emergent light path of the collimation system and is used for coupling the coupled light to human eyes. According to the scheme, high-brightness color display of the near-to-eye display device can be realized.

Description

technical field [0001] The present disclosure relates to the technical field of augmented reality display, and in particular to a novel augmented reality near-eye display device and augmented reality display device. Background technique [0002] Augmented reality technology is a technology that projects virtual images to the human eye while allowing users to view the surrounding environment. Due to the unique feature of this technology that can superimpose the projected images on the real world perceived by users, it is widely used in the military. , industrial design and manufacturing, medical and entertainment and other fields of virtual reality and augmented reality have been widely used. [0003] Currently, image sources for display devices in augmented reality technology mainly include Liquid Crystal on Silicon (LCOS), Organic Light Emitting Display (OLED), Liquid Crystal LCD (Liquid Crystal Display), and Micro-LED microarrays (Micro-Light Emitting Display). Emitting D...
