Abstract

A method for fabricating a stretchable display panel includes: providing a substrate, wherein a displaying unit, a connecting unit and a hollowed-out region are provided on the substrate; forming film-layer components on the substrate, wherein orthographic projections of the film-layer components on the substrate are within the displaying unit, the connecting unit and the hollowed-out region; forming a first planarization layer on a surface of the film-layer components that is away from the substrate; forming a color-film layer on one side of the first planarization layer that is away from the substrate, wherein an orthographic projection of the color-film layer on the substrate is within the displaying unit; forming a color-film protecting layer on one side of the color-film layer that is away from the substrate; and performing an ashing process to the hollowed-out region, to remove the first planarization layer and the film-layer components within the hollowed-out region.

Claims (19)

1 . A stretchable display panel, wherein the stretchable display panel comprises a displaying unit, a connecting unit and a hollowed-out region, the hollowed-out region is provided between the displaying unit and the connecting unit, and the stretchable display panel comprises:

film-layer components, wherein the film-layer components are in the displaying unit and the connecting unit;

a first planarization layer, wherein the first planarization layer is provided on one side of the film-layer components, and an orthographic projection of the first planarization layer on the film-layer components are within the displaying unit and the connecting unit;

a color-film layer, wherein the color-film layer is provided on one side of the first planarization layer that is away from the film-layer components, and an orthographic projection of the color-film layer on the film-layer components is within the displaying unit; and

a color-film protecting layer, wherein the color-film protecting layer is provided on one side of the color-film layer that is away from the film-layer components, and covers merely the displaying unit and the connecting unit;

wherein the film-layer components comprise a flexible matrix, a flexible-matrix protecting layer, a thin-film-transistor component, a second planarization layer, a source-drain-electrode protecting layer, an organic luminescent component and a columnar supportor that are arranged in stack, orthographic projections of the flexible matrix, the flexible-matrix protecting layer and the second planarization layer on the film-layer components are within the displaying unit and the connecting unit, and orthographic projections of the thin-film-transistor component, the organic luminescent component and the columnar supportor on the film-layer components are within the displaying unit.

2 . The stretchable display panel according to claim 1 , wherein the stretchable display panel further comprises:

a substrate, wherein the substrate is provided on a surface of the film-layer components that is away from the first planarization layer.

3 . The stretchable display panel according to claim 1 , wherein the stretchable display panel further comprises:

a back film, wherein the back film is adhered to a surface of the film-layer components that is away from the first planarization layer.

4 .
