Abstract

The invention discloses a single holographic diffraction optical waveguide lens and a 3D display device using the lens. The single holographic diffraction optical waveguide lens comprises a diffraction optical waveguide lens unit; the diffraction optical waveguide lens unit comprises an optical waveguide and three functional areas arranged in the upper or lower surface of the optical waveguide; and the three functional areas, namely, the first, second and third functional areas, are arranged in different positions of the same planar space of the optical waveguide, used to output an image light bean to the human eyes, and are provided with holographic diffraction gratings respectively. The space multiplexing single holographic diffraction optical waveguide lens is provided with the multiple functional areas creatively, the single waveguide can satisfy requirements for a near 3D display system, and compared with a multi-layer holographic diffracted waveguide lens, the lens of the invention is much thinner.

Description

technical field [0001] The invention relates to the technical field of display equipment, and more specifically, relates to a holographic diffraction optical waveguide lens and a three-dimensional display device using the optical waveguide lens. Background technique [0002] With the development of virtual reality and augmented reality technologies, near-eye display devices have developed rapidly, such as Google Glass of Google and Hololens of Microsoft. The near-eye display of augmented reality is a technology that images light fields in real space, and can take into account both virtual and real operations. Coupling image light into the human eye using traditional optical waveguide components has been used, including the use of prisms, mirrors, transflective waveguides, holograms, and diffraction gratings. The optical waveguide display system uses the principle of total reflection to realize light wave transmission, combined with diffraction elements to realize directiona...
