Problems solved by technology

However, the head-mounted display system with the above-mentioned structure has at least the following defects: the field of view β (monocular field of view) of the head-mounted display system is limited, and it is difficult to increase; There is no included angle, so the requirements for structural design accuracy are high, and it is easy to reduce the yield rate during mass production; the baffle plate in the middle of the two display screens will increase the structural complexity and weight burden of the system
[0004] Therefore, the research on the virtual reality head display system still needs to be in-depth

Abstract

The invention provides a virtual reality display screen, a head display device and a virtual reality head display system. The display screen comprises a display panel and a first polaroid, wherein thefirst polaroid is arranged on a first surface of the display panel, the first polaroid comprises multiple first regions and multiple second regions, the multiple first regions and the multiple secondregions are alternately distributed in the first direction, and polarization directions of the first regions and the second regions are perpendicular to each other. The display screen is advantaged in that the whole display screen can be seen by two eyes of a user, the visual view field and the double-eye overlapped region of the virtual reality head display system can be greatly improved, the virtual world immersion effect of the user is enhanced, compared with the prior art, the use of one display screen can eliminate restriction of the strict alignment relationship in the dual display screen mounting process, and the production yield is improved.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a display screen, a head-mounted display device and a virtual reality head-mounted display system for virtual reality. Background technique [0002] refer to figure 1 , the virtual reality (VR) head-mounted display system in the related art usually adopts the form of dual display screens (left-eye display screen 4 and right-eye display screen 6 ) and dual lenses (left-eye lens 3 and right-eye lens 5 ), that is, human The left eye 1 and the right eye 2 respectively correspond to a display screen and a lens, and the observer can respectively see the images on the respective display screens through the two eyes to obtain a stereoscopic vision, wherein the image 9 seen by the left eye and the image 9 seen by the right eye After the images 10 are overlapped, an overlapping image 7 seen by both eyes is obtained. But there is a very important structural light barrier 8 (lens b...
