A near-eye display device

Abstract

The invention discloses a near-to-eye display apparatus relating to the field of display technology, and aims to solve the problem that existing near-to-eye display devices are inconsistent with the demand for lightness and thinness due to the necessity of wearing diopter corrective glasses of users with poor eyesight. The near-to-eye display apparatus includes a laser two-dimensional scanning unit, a collimating coupling unit, an optical waveguide component and a lens array. The laser two-dimensional scanning unit is sued for sequentially changing a propagation direction of a laser beam emitted by itself in a two-dimensional direction to output a laser beam array. The collimating coupling unit is used to collimate the laser beam emitted by the laser two-dimensional scanning unit and then couple the collimated laser beam array into the optical waveguide component. The optical waveguide component includes a plurality of semi-reflective and semi-transmissive surfaces for transmitting the laser beam array input into the optical waveguide component to a display side. A plurality of lenses in the lens array is in one-to-one correspondence with the plurality of semi-reflective and semi-transmissive surfaces. The plurality of lenses is used to converge the laser beam array output by the plurality of semi-reflective and semi-transmissive surfaces to a same position. The near-to-eye display apparatus is used to display images.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a near-eye display device. Background technique [0002] Virtual reality (Virtual Reality, VR) and augmented reality (Augmented Reality, AR) both belong to the category of near-eye display, that is, the display screen is placed relatively close to the user's eyes, so that the user can experience the virtual world or the world that combines virtual and real. Roaming, virtual reality and augmented reality correspond to non-transmissive and transmissive near-eye displays, respectively. [0003] figure 1 It is a near-eye display device in the prior art, which is mainly composed of three parts: optical waveguide element 01, projection system 02 and microdisplay 03. 012 Realize the coupling incident and exit of light. Specifically, the image displayed on the micro-display 03 is amplified by the projection system 02 and then projected onto the entrance reflection surface 011...
