AI Technical Summary

Technical Problem

Existing AR display devices suffer from a mismatch between the actual focusing distance of the left and right eyes and the distance to the image when displaying stereoscopic images, leading to convergence problems that can cause discomfort and dizziness for users.

Method used

The device employs a focusing assembly, including a zoom element and a meta-lens. It obtains the user's focusing position through an eye tracker, controls the zoom element to zoom, adjusts the imaging focal plane of the virtual image, and eliminates chromatic aberration through the meta-lens, thereby achieving adaptive zoom of the virtual image.

Benefits of technology

It alleviates the focusing and convergence conflict in AR displays, improves the user experience, ensures the imaging quality of virtual images, and facilitates the miniaturization design of AR optical systems.
