Abstract
A supporting layer and a flexible display panel are provided. Openings and notches are repeatedly disposed in the supporting layer, and a first striped hollow portion of the notch extends through an edge and/or a side of the supporting layer, such that an extensibility of a module stacked structure can be improved as a whole to ensure an adaptability and coordination between the supporting layer and film layers of the module stacked structure. Thus, a bending performance of an organic light emitted diode module is improved, a risk of the film layers being peeled off or broken is reduced, and a bending lifespan of the module stacked structure is improved.
Claims20
A supporting layer, comprising a plurality of non-bending areas, a bending area disposed between two adjacent non-bending areas, and a plurality of openings and a plurality of notches repeatedly disposed in the bending area,
- wherein the openings are arranged row by row along a first direction from one of the non-bending areas to the bending area, and a width direction of the openings is the same as the first direction;
- wherein the notches are arranged with a row inserted between two adjacent rows along the first direction, and a width direction of the notches is the same as the first direction;
- wherein each of the notch comprises a first striped hollow portion and a first arc-shaped hollow portion that are in contact with and connected to each other, a vertex of the first arc-shaped hollow portion is disposed on an extension centerline of the first striped hollow portion along a second direction, and the first striped hollow portion extends through an edge and/or a side of the supporting layer;
- and
- wherein the second direction is a length direction of the notches or the openings, and the first arc-shaped hollow portion comprises a semi-elliptical shape.
