Compact-type waveguide light field AR (augmented reality) display device

Abstract

The invention discloses a compact-type waveguide light field AR (augmented reality) display device, and the display device comprises a first image source and a second image source, which respectivelygenerate a first depth virtual image and a second depth virtual image; a first coupling mirror group and a second coupling mirror group which respectively perform the modulation of the virtual image light transmitted by the first image source and the second image source, and then perform the coupling and input the virtual image light into a first waveguide lens and a second waveguide lens; the first waveguide lens which transmits the virtual image light emitted by the first image source to a depth modulation module; the depth modulation module which reflects the virtual image light which is coupled and emitted by the first waveguide lens to human eyes; and the second waveguide lens which transmits and couples the virtual image light emitted by the second image source to the human eyes, wherein the environment light are transmitted to the human eyes through the depth modulation module and the waveguide lenses. The display device of the invention realizes multi-depth light field displaythrough double waveguides and the depth modulation module, and effectively solves a problem of adjusting the convergence conflicts.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to a compact waveguide light field augmented reality display device. Background technique [0002] Augmented reality technology (Augmented Reality, referred to as AR), is a technology that calculates the position and angle of the camera image in real time and adds the corresponding image. The goal of this technology is to put the virtual world on the screen and interact with the real world. . This technology was proposed in 1990. With the improvement of the computing power of portable electronic products, it is expected that the application of augmented reality will become more and more extensive. [0003] Augmented reality technology not only shows real world information, but also displays virtual information at the same time, and the two kinds of information complement and superimpose each other. In the visual augmented reality, users use the head-mounted display to m...

Problems solved by technology

[0007] However, the above two display systems require several laminated planar optical units or depth adjusters, which occupy a large volume and high cost.

[0008] At present, most display solutions are still bulky. For example, the newly released NED+Glass X2, a well-known AR company in China, has a shape similar to a helmet, which is far from the shape of glasses in consumers’ minds.
