AI Technical Summary

Technical Problem

Existing display devices have insufficient bonding strength between the sealing components and the encapsulation substrate, resulting in poor durability and an inability to effectively resist external impacts.

Method used

A sealing component is placed between the display panel and the packaging substrate, and a fusion zone is formed by strong light irradiation to improve the bonding force between the sealing component and the packaging substrate. The fusion zone is separated from the metal wiring layer and overlaps in the thickness direction to enhance the bonding strength.

Benefits of technology

It improves the durability of the display device, enhances its resistance to external impacts, and improves the bonding force between the sealing components and the packaging substrate.
