Abstract

The invention provides a near-eye display device, which includes a planar waveguide array display device, an infrared emitting device, an infrared camera module and an infrared reflection and diffraction element capable of converting plane waves into spherical waves. The planar waveguide array display device includes a display output light group, a light guide substrate and at least one inclined coupling surface. The inclined coupling surface is covered with a spectroscopic film that is transparent and reflective to the visible light band. The infrared reflective diffraction element is arranged on the side of the light guide substrate close to the human eye or away from the human eye. The reflected and outgoing optical axis of the infrared reflective diffraction element is substantially parallel or coaxial with the optical axis of the infrared camera module. The infrared light emitted by the infrared emitting device covers the range of the human eye, and the infrared light reflected by the human eye is reflected and diffracted by the infrared reflection diffraction element, and the virtual image of the human eye formed by the infrared camera module is captured. The near-eye display device can obtain a clear ortho-eye image without directly facing the human eyes, does not interfere with the visual effect of the user viewing a virtual picture, and can be used for eyeball tracking, iris recognition, and the like.

Description

technical field [0001] The present invention relates to the technical field of augmented reality, in particular, to a near-eye display device. Background technique [0002] Augmented Reality (AR, Augmented Reality) is a technology that uses virtual objects or information to augment real scenes, and is widely used in scientific research, military, industry, games, video, education and other fields. With the development and wide application of emerging technologies, security issues such as the protection of personal privacy and payment usage will also be highlighted. Iris recognition for identity authentication is considered to be a biotechnology second only to DNA recognition. Applying iris recognition technology to near-eye display devices solves the identity verification problems of users using display devices, transaction payment, etc., which is a technological development trend. [0003] The iris recognition module requires that the camera that captures the human eye ima...
