Problems solved by technology
This image segmentation display method is not only complex in structure and difficult to assemble the device, but also difficult in image segmentation and splicing, and the image effect is not good.
[0005] Adding and positioning virtual objects in three-dimensional space is the main purpose of the AR system. However, the current 3D display systems including the above-mentioned technical solutions have the disadvantage of a small field of view, and the existing solutions are difficult to achieve a wide viewing angle, such as greater than 60 degree of 3D display

Abstract
The invention discloses a wide viewing angle waveguide lens, a manufacturing method and a head-mounted three-dimensional display device. By using a nano grating structure having a concentrated light field viewing angle amplifying function, namely a grating lens function, the viewing angle of three-dimensional virtual information is amplified and projected in front of human eyes; a virtual object is perfectly fused with a real scene via the wide viewing angle waveguide lens; because the viewing angle is amplified, human eyes are difficult in perceiving the fused image of the virtual object and the real scene, and the experience is more real; simultaneously based on the holographic principle, computer-generated holography can be conveniently combined with a nano structured functional light field lens, thereby realizing visual fatigue-free, high-brightness and head-mounted 3D augmented reality display schemes and devices, and conveniently supporting dynamic focusing of 3D display images.
Description
technical field [0001] The invention belongs to the field of three-dimensional image display, and in particular relates to a wide viewing angle waveguide lens, a manufacturing method and a head-mounted three-dimensional display device. Background technique [0002] Augmented reality (AR) technology is a new technology that "seamlessly" integrates real world information and virtual world information. Sound, taste, touch, etc.), through science and technology such as computers, simulate and then superimpose, apply virtual information to the real world, and be perceived by human senses, so as to achieve a sensory experience beyond reality. The real environment and virtual objects are superimposed on the same screen or space in real time. One of the characteristics of the AR system: adding and positioning virtual objects in a three-dimensional scale space is a difficult point in display technology. [0003] US patent US008014050B2 discloses an optical holographic phase plate f...
