AI Technical Summary

Technical Problem

Existing transparent display devices suffer from interface reflection and refraction problems within the transparent area, leading to reduced transmittance and purity.

Method used

In transparent display devices, by removing the portion of the touch buffer layer, the touch intermediate insulating layer, and the first protective layer in the transparent area, and using an encapsulation layer and a second protective layer with similar refractive indices, combined with the design of a light-shielding layer, interface reflection and refraction are reduced, thereby improving the transmittance and purity of the transparent area.

Benefits of technology

It effectively reduces interface reflection and refraction in the transparent area, improves the transmittance and purity of transparent display devices, enhances visibility, and achieves environmental, social, and governance (ESG) goals.
