Problems solved by technology

Traditional viewing methods can no longer meet users' requirements for resolution, field of view, and portability.
Although multifunctional and miniaturized electronic display devices can bring convenience to users, "portable" and "miniaturization" also limit the size of the display screen, and a small display screen is likely to cause eye fatigue for users

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the drawings and embodiments.

[0024] reference figure 1 and figure 2 As shown, the head-mounted micro-projection stereo vision display includes three parts: a support unit, an image display unit, and an optical system unit.

[0025] The supporting unit includes a support 1 located on the top of the wearer's head and a support 2 located around the wearer's head. There is a fastening bolt at the intersection of the bracket 1 and the bracket 2 for fixing the bracket and adjusting the size of the helmet. The bracket can adopt a structure similar to a head massager, and an optical system composed of a lens and an analyzer is placed at the position of a traditional eye massager, facing the user's eyes. When the user wears it, first loosen the fastening bolt, put the bracket on the head, and then tighten the fastening bolt to fix the bracket.

[0026] Such as figure 1 As shown, the image display unit inclu...

Abstract

The invention discloses a headset micro-projection stereoscopic vision display belonging to the field of virtual reality. The headset micro-projection stereoscopic vision display comprises a supporting unit, an image display unit and an optical system unit. Through the four-projection double-screen splicing technology of a micro projector, the field angle is increased, and the image quality is improved so that the resolution of a display screen can reach 1600*800. Through polarizer and analyzer equipment in different polarization directions added to the micro projector and an optical system before eyes of a user, the stereoscopic image display function is realized. Through the lens group added to the optical system, the function of easing the use fatigue of a user is realized, and market potential is great.

Description

Technical field [0001] The invention relates to a head-mounted micro-projection stereo vision display, in particular to a head-mounted micro-projection stereo vision display adopting an optical structure, belonging to the field of virtual reality. Background technique [0002] Virtual Reality (Virtual Reality, referred to as VR, also translated as Lingjing, Huanzhen) is a high-tech that has emerged in recent years, also known as Lingjing technology or artificial environment. Virtual reality is the use of computer simulation to generate a three-dimensional virtual world, providing users with the simulation of sight, hearing, touch and other senses, allowing users to observe things in the three-dimensional space in a timely manner and without restrictions. . [0003] Head-mounted display (HMD), also known as near-eye display, was developed by the Fraunhofer Institute of Optical Microsystems in Germany. It is a portable high-immersion stereoscopic image display device widely used in ...
