Problems solved by technology

[0003] In the existing short-distance virtual reality modules, semi-transparent and semi-reflective films are used to realize the return of the light path, but the introduction of semi-transparent and semi-reflective films will cause serious ghost images and noise between the wave plate and the lens attached to the screen surface. Even if the wave plate attached to the surface of the screen is coated with an anti-reflection coating, it can only reduce ghost images and stray light, but cannot completely eliminate them.
The image is not clear, and it is easy to cause problems such as dizziness of the user

Abstract

The embodiment of the invention discloses a virtual reality optical module and a virtual reality device. The virtual reality optical module includes a first absorption type polaroid, a first phase retardation piece, a selective transflective film, a first lens structure, a second phase retardation piece, and a reflective polaroid. The first lens structure includes at least one first lens; the selective transflective film is used for transmitting light in a first circular polarization direction and reflecting light in a second circular polarization direction, wherein the first circular polarization direction and the second circular polarization direction are opposite to each other. Therefore, short-distance virtual reality imaging without ghost images and stray light can be realized; and the performance of the virtual reality device can be improved.

Description

technical field [0001] The embodiment of the present invention relates to virtual reality technology, in particular to a virtual reality optical module and a virtual reality device. Background technique [0002] Virtual reality (Virtual Reality, VR) technology is a computer simulation system that can create and experience virtual worlds, and has been widely used in game entertainment, education, medical treatment, military simulation and other aspects. [0003] In the existing short-distance virtual reality modules, semi-transparent and semi-reflective films are used to realize the return of the light path, but the introduction of semi-transparent and semi-reflective films will cause serious ghost images and noise between the wave plate and the lens attached to the screen surface. Even if the wave plate on the surface of the screen is coated with an anti-reflection coating, it can only reduce ghost images and stray light, but cannot completely eliminate them. As a result, t...
