US 2022/0036771 A1 · FLEXIBLE DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR

Abstract

A flexible display panel and a manufacturing method therefor. The flexible display panel comprises an organic insulating layer and a metal layer disposed on the organic insulating layer, and is divided into a display region located in the middle, a binding region located outside the display region, and a bending region located between the display region and the binding region. The organic insulating layer is provided with a plurality of protrusions in the bending region so that the surface of the organic insulating layer is uneven in the bending region. The metal layer comprises a plurality of metal wires penetrating the bending region, and each metal wire covers a part the protrusions of the organic insulating so that the surface the metal wire is also uneven along with the organic insulating layer. During the bending of the flexible display panel, the protrusions would release part of stress.
