Abstract

The present invention provides a VR device, comprising: a relatively rotatable outer lens barrel, an inner lens barrel, and a lens installed on the inner lens barrel and / or the outer lens barrel; the inner lens barrel and the outer lens One of the tubes is equipped with a first polarizing film, and the other is equipped with a second polarizing film; wherein, when the inner lens barrel and the outer lens barrel rotate relatively, the first polarizing film and the second polarizing film The polarization direction of the polarizing film remains the same or differs. The technical scheme of the present invention can perform light-shielding treatment on the lens on the VR device.

Description

technical field [0001] The present invention relates to the field of optical technology, in particular to a VR device. Background technique [0002] VR (Virtual Reality, Virtual Reality) technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment, and through multi-source information fusion, interactive three-dimensional dynamic vision and entity behavior The system simulation immerses the user in this simulated environment. [0003] Existing VR devices include a lens for viewing virtual images, through which a user views a display screen fixed inside the VR device or detachably installed on the VR device. When the VR device is in an external environment with strong light, more light passes through the lens and reaches the vicinity of the display screen. If too much light reaches the vicinity of the display, it can easily damage the display. In order to solve this defect, a new VR device...
