Abstract
The present application discloses a support film layer and a flexible display panel. By periodically arranging at least one elliptical hollow structure and a plurality of shuttle-shaped hollow structures in a bending region of the support film layer, stress concentrations in the bending region can be weakened, which is beneficial to increase a bending lifespan of the support film layer. The present application can improve an overall ductility of the flexible display panel, increase a bending performance of the flexible display panel, reduce a risk of peeling and fracture between film layers, and increase production yields of products.
Claims8
A flexible display panel, comprising:
- a flexible substrate;
- and
- a support film layer disposed on a side of the flexible substrate,
- wherein the support film layer comprises a bending region and non-bending regions on two opposite sides of the bending region;
- wherein the bending region comprises at least one elliptical hollow structure and a plurality of shuttle-shaped hollow structures, which are arranged periodically;
- wherein the elliptical hollow structure and the shuttle-shaped hollow structures have a same width direction, the elliptical hollow structure and the shuttle-shaped hollow structures have a same length direction, and the width direction is a bending direction of the support film layer;
- wherein each of the shuttle-shaped hollow structures comprises a first semi-elliptical hollow structure, a rectangular hollow structure, and a second semi-elliptical hollow structure, which are sequentially connected to each other along the length direction;
- wherein in the length direction, the elliptical hollow structure is disposed between two adjacent first semi-elliptical hollow structures and/or second semi-elliptical hollow structures;
- wherein in the width direction, the elliptical hollow structure is disposed between two adjacent rectangular hollow structures;
- wherein the first semi-elliptical hollow structure is same as half of the elliptical hollow structure in the length direction, and the second semi-elliptical hollow structure is same as another half of the elliptical hollow structure in the length direction;
- and
- wherein a width of the rectangular hollow structure is twice that of a semi-minor axis of the elliptical hollow structure,
- wherein in the length direction, a distance between adjacent two of the elliptical hollow structures and the first semi-elliptical hollow structure or the second semi-elliptical hollow structure ranges from 100 μm to 240 μm.
