AI Technical Summary

Technical Problem

Flexible displays face issues with stress concentration on connection wires during bending, leading to potential cracks, and the manufacturing process is hindered by the need for a separate anti-etching layer requiring a mask process.

Method used

A display panel design that incorporates a bending wire and a planarization layer made of organic material to protect connection wires, and uses an etching process to form grooves on a glass substrate, eliminating the need for a separate anti-etching layer, thereby simplifying the manufacturing process.

Benefits of technology

The solution prevents damage to connection wires and enhances manufacturing productivity by maintaining substrate rigidity while reducing the number of process steps.
