Abstract

The invention discloses a near-eye display structure, comprising an angle selection film, the display structure further comprises a screen, a first semi-transparent and semi-reflective film arranged on the side of the angle selection film facing the human eye and arranged obliquely, and a The second semi-transparent and semi-reflective film on the side of the angle-selective film away from the human eye, the first semi-transparent and semi-reflective film, the angle-selective film, and the angle-selective film disposed diagonally above the first semi-transparent and semi-reflective film and facing the angle-selective film The screen of the film is enclosed to form a light walking space, the side of the second transflective film away from the human eye is a curved surface that protrudes outward, and the angle between the film and the second transflective film is selected. There is a spacing adjustment structure for adjusting the spacing by moving toward or in the opposite direction. With the arrangement of the structure, the perspective efficiency is improved; and by adjusting the position of the outermost mirror, the definition of the image viewed by the human eye can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of optical display, and particularly relates to a near-eye display structure. Background technique [0002] One of the core technologies in the field of Augmented Reality (AR, Augmented Reality) is a transmissive optical display system, which can superimpose computer-generated images on the user's real vision and seamlessly integrate virtual and real images. The combination of the digital world and the real world will bring users a new experience. At present, AR technology has been widely used in the fields of games, retail, education, industry and medical care. [0003] At present, augmented reality technology usually adopts transmissive optical display methods, including solutions such as holographic gratings, reflective waveguides, ordinary reflective prisms, and free-form surface prisms. In the existing optical display structure, the high-brightness screen is generally an opaque screen, and the locatio...
