Near-eye display is an important component of an augmented reality/virtual reality system, determining the quality of the reproduced display image, affecting the viewing experience of the user.
Binocular parallax type near-eye display can only reproduce one image in the pupil range of a single human eye, and stereoscopic vision is generated by utilizing the binocular to receive two-dimensional parallax images through brain fusion. The resolution of the binocular parallax near-eye display reproduction image is high, but the display mode cannot present stereoscopic vision for a single eye, and visual fatigue is easily caused when the binocular parallax near-eye display reproduction image is watched for a long time.
