VR glasses based on laser projection technology

Abstract

The invention discloses VR glasses based on a laser projection technology. A light source and glasses split mode is adopted for realization. A dodging device, a spatial light modulator, a projection lens and a projection screen are arranged on a glasses body, the emergent end of a laser light source coupling element is connected with the incident end of the dodging device, the emergent end of thedodging device is connected with the incident end of the spatial light modulator, and the projection lens and the emergent end of the spatial light modulator are connected and imaged on the projectionscreen. Through the VR glasses based on a laser projection technology, laser light is adopted as a light source, the wider color gamut of the laser light source is utilized, and more colors can be displayed; if the laser light source is externally arranged, the projection screen is used for imaging, the design of an imaging lens system is simplified, the weight of the VR glasses body is reduced,the wearing comfort is improved, meanwhile, the endurance time is prolonged, and better experience and immersion are brought to a user.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to VR glasses based on laser projection technology. Background technique [0002] Virtual reality (VR) is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. It is a system simulation of multi-source information fusion, interactive three-dimensional dynamic vision and entity behavior. Immerse the user in that environment. The goal of this technology is to give participants a sense of immersion in the virtual environment. The display principle is that the left and right eye screens display the images of the left and right eyes respectively. After seeing this image with binocular parallax, the human eye produces a three-dimensional feeling in the mind. In order to get a better sense of immersion, users have the following three requirements for virtual reality technology: [0003] 1. A large im...

Problems solved by technology

[0007] The light sources of current VR glasses all use flat panel display technologies, such as LCD, LED, and OLED, which have many problems such as high heat, high energy consumption, and complex imaging lens systems.

Moreover, the resolution is low, and it is easy to produce screen window effect, which affects the viewing experience of users. Moreover, when VR glasses are used for a long time, they are prone to generate heat. comfort, and will also affect the service life of VR glasses
