Abstract

The invention discloses resin holographic waveguide lenses and a preparation method thereof, and a three-dimensional display device constructed thereof. The resin holographic waveguide lenses comprise one piece, two pieces, and three pieces or three pieces above resin holographic waveguide lens units, the resin holographic wave guide lens unit comprises a polymer lining and a functionality film arranged on the polymer lining, a functionality region is arranged on the functionality film, and a Nano diffraction grating is arranged within the functionality region. According to the resin holographic waveguide lenses, the lenses have good image coupling and coupling efficiency, under the condition of using Nano diffraction grating to guarantee enough field view and observation area, the lenses have the advantages of low copy cost and high fidelity factor, the resin material prepared resin holographic waveguide lenses can be formed by impact and does not require regular lens processing.

Description

technical field [0001] The invention relates to the technical field of display equipment, and more specifically, to a resin holographic waveguide lens, a preparation method thereof, and a 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, simulated and then superimposed, so that people can obtain a sensory experience beyond reality. In fields where virtual display technology has been applied, such as cutting-edge weapons, research and development of aircraft, visualization of data models, virtual training, entertainment and art, augmented reality technology also has great potential. In addition, because AR has the characteristic of enhancing the display output of the real environment, it has more obvious advantages than virtual display technology VR ...
