Abstract

The invention discloses a pair of AR (Augmented Reality) glasses and an optical path for the AR glasses. The AR glasses comprise a display panel, and the optical path comprises a semi-transparent semi-reflective spectroscope arranged on the light path of image light emitted by the display panel, a polarization splitting curved surface semi-reflective mirror arranged on the light path of the reflected image light, and a reflective mirror arranged on the light path of the transmitted image light. The semi-transmitting and semi-reflecting spectroscope is used for dividing the image light into reflected image light and transmitted image light. The polarization beam splitting curved surface half-reflecting mirror is used for dividing the reflected image light into reflected propagated verticalpolarization image light and transmitted parallel polarization image light. The reflector is used for reflecting the transmission image light to the polarization splitting curved surface half-reflecting mirror. Thus, the optical path improves the utilization rate of the image light, so that the AR glasses can reduce the display brightness of the display panel and ensure the imaging quality of thedisplay panel, and the problems of high power consumption and high heat productivity of the display panel are solved.

Description

technical field [0001] This application relates to the field of optics, in particular to an optical path and AR glasses. Background technique [0002] Existing augmented reality (augmented reality, AR) glasses are equipped with a beam splitter, and the image light emitted by the display panel is reflected by the beam splitter, superimposed on the curved half mirror and the scene light, and transmitted through the beam splitter, then transmitted to the eyes. Overlay images for augmented reality. However, part of the image light will be lost after being transmitted through the beam splitter, resulting in low light utilization efficiency. Therefore, it is necessary to increase the display brightness of the panel, resulting in problems such as high power consumption and high heat generation. Contents of the invention [0003] The present application provides an optical path for AR glasses, the AR glasses include a display panel, and the optical path includes: [0004] The s...
