The invention discloses a near-to-eye display structure. The display structure includes an angle selection diaphragm, and also includes a screen, a first semi-transparent and semi-reflective diaphragmwhich is obliquely arranged on the side, facing the human eyes, of the angle selection diaphragm, and a second semi-transparent and semi-reflective diaphragm which is arranged on the side, away fromthe human eyes, of the angle selection diaphragm. A light walking space is defined by the first semi-transparent and semi-reflective diaphragm, the angle selection diaphragm and a screen which is arranged obliquely above the first semi-transparent and semi-reflective diaphragm and faces the angle selection diaphragm; one side surface, far away from the human eyes, of the second semi-transparent and semi-reflective diaphragm is a curved surface protruding outwards; and a distance adjusting structure for adjusting the distance through opposite or reverse movement is arranged between the angle selection diaphragm and the second semi-transparent and semi-reflective diaphragm. Through the structural arrangement, the perspective efficiency is improved; and through the position adjustment of a reflector at the outermost side, the definition adjustment of the image seen by the human eyes is realized.
Description
technical field [0001] The invention belongs to the technical field of optical display, and in particular 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 penetrating optical display system, which can superimpose computer-generated images on the user's real vision, and seamlessly blend virtual images 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 games, retail, education, industry and medical fields. [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 screens are generally opaque screens, and the position of the ...
