Embodiment Construction

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] The near-eye light field display system and control circuit according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0027] Due to the existing 3D display technology based on binocular stereo vision, the focus distance of the user's left and right eyes on the display screen is not the same as the convergence distance of the left and right eyes at the 3D display, that is, there is a problem of convergence adjustment conflicts, which requires the user's left ...

Abstract

The invention provides a near-vision optical field display system and a control circuit. The system comprises N layers of holographic elements, waveguides corresponding to each layer of holographic elements and an imaging device; each layer of holographic elements comprises a holographic input sub-element and a holographic output sub-element, which occur in pairs; within a display period, the imaging device projects light to the holographic input sub-element in the i layer of holographic elements according to a preset time interval, the holographic input sub-element emits the projected light to the waveguide corresponding to the i layer for conduction to arrive at the holographic output sub-element of the i layer, the light output by the holographic output sub-elements of the layers are fused and output based on time division multiplexing so as to form 3D images in human eyes. By adoption of the system, the real optical field in a three-dimensional space can be simulated, natural 3D display is realized, and the visual fatigue and dizziness caused by convergence condition conflict in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of stereo vision, in particular to a near-eye light field display system and a control circuit. Background technique [0002] With the development of virtual reality (Virtual Reality, VR) equipment and augmented reality (Augmented Reality, AR) equipment, near-to-eye display (Near-to-Eye Display, NED) technology has emerged as the times require, and has gradually become a research hotspot. [0003] In the current near-eye display technology, after the user wears an augmented reality device (such as Microsoft's HoloLens), the displayed 3D object is a stereoscopic vision formed by displaying different images to the user's left and right eyes respectively. [0004] However, the 3D display technology based on binocular stereo vision has the problem of conflicting convergence conditions, which makes users feel visual fatigue and dizziness easily when wearing the device for a long time. Therefore, how to solve thi...
