AI Technical Summary

Technical Problem

Existing glasses-type wearable displays are burdensome in terms of size and weight, and the image quality needs to be improved, especially in terms of field of view (FOV) and image sharpness.

Method used

The design employs a transparent substrate with a light source module array and a pinhole array. The light source module array generates images through an optical driver and provides them to the user through the pinhole array. The pinhole array consists of multiple micro-cluster pinholes, and the aperture and spacing of the micro-cluster pinholes are optimized to improve image quality.

Benefits of technology

It achieves a wider field of view (FOV) and higher image quality, while reducing the size and weight of the device and reducing noise interference.
