A large field of view optical waveguide lens with transmission decoupling

Abstract

The invention discloses a large-field optical waveguide lens for transmission decoupling. The lens comprises a projection module, a waveguide module, and a light modulation module, wherein the projection module is at one end of the waveguide module, the light modulation module is at the other end of the waveguide module, the light modulation module comprises a liquid crystal layer, a quantum dot emitting layer, and an antireflection layer that are overlaid in sequence, and the liquid crystal layer is close to the waveguide module. Multi-color light transmission is decoupled, and single-color light transmission is adopted, so that a largest transferable angle spectrum range is obtained, and the FOV is enlarged; further, single color avoids problems like color shift caused by interference ofmultiple-color light; and the optical structure is guaranteed light and thin, further, large field-of-view, full color near eye display is realized, the delivered image is clear, and visual experience is improved.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a transmission decoupling large-field optical waveguide lens. Background technique [0002] In recent years, with the development and progress of computing power, micro-display optics, sensing technology and AI (artificial intelligence) technology, the helmet display system originated from pilot combat assistance can achieve low power consumption and thinness, and has become a kind of Wearable smart device, a kind of smart glasses based on augmented reality technology (Augmented Reality). AR glasses generate matching virtual information or images through the perception and calculation of the real world, and superimpose the real world through the optical display system, so as to increase the user's perception of the real world. AR glasses involve key technologies such as environment recognition, tracking and positioning, 3D registration and modeling, image rendering, and ...

AI Technical Summary

Problems solved by technology

At present, companies such as Microsoft and Waveoptics use a multi-color multi-waveguide transmission scheme in order to obtain full-color display. However, in this technology, multi-waveguides increase the optical thickness and weight. At the same time, multi-channel transmission superposition limits the maximum transmittable angular spectrum range. It also leads to more optical crosstalk problems, affecting the clarity and color of imaging

[0004] The existing technology does not solve the problems of multi-color crosstalk and channel superposition limiting the field of view in the full-color imaging solution.
