Ocular lens system and head-mounted display

Abstract

The invention discloses an ocular lens system and a head-mounted display. The ocular lens system comprises a display screen, a concave reflecting mirror and a positive lens set, wherein the concave reflecting mirror reflects light emitted by the display screen onto the positive lens set, and the positive lens set refracts light reflected by the concave reflecting mirror to people's eyes. The concave reflecting mirror and the lens sets cooperate with each other to reduce the size of the ocular lens system. In a light convergence process, the concave reflecting mirror bears partial focal power of the ocular lens system, which lowers the requirements of the ocular lens system on the focal power of the lens set, minimizes color difference of the lens set, and reduces the processing material of the lens set. Since the concave reflecting mirror may not generate color difference during a light convergence process, the color difference of the ocular lens system is lowered substantially, the imaging quality is improved, and the mass and the size of the ocular lens system are reduced. The ocular lens system is applicable to the head-mounted display, and provides perfect visual experience for users.

Description

technical field [0001] The invention relates to the technical field of visual equipment, in particular to an eyepiece system and a head-mounted display. Background technique [0002] At present, with the continuous development of technology, head-mounted displays have entered the civilian market, and more and more people have begun to use such products to enjoy an immersive visual experience through the eyepiece system in the head-mounted display. However, in the design scheme of the eyepiece system of the head-mounted display currently on the market, the lens group is generally required to bear the optical power of the entire eyepiece system, so multiple lenses are required to adapt to each other, and the chromatic aberration produced by the multiple lenses makes the imaging of the eyepiece system The quality is greatly reduced, and the overall eyepiece system has the disadvantages of large volume and high quality. The bulky head-mounted display puts a lot of pressure on th...
