Abstract

Disclosed in embodiments of the present disclosure are a display panel and a manufacturing method therefor, and a display apparatus. The display panel includes: a base substrate; an organic functional film layer provided on the base substrate; an insulating layer provided on the organic functional film layer, a plurality of dents distributed at intervals are provided on one side of the insulating layer distant from the organic functional film layer; and an amorphous silicon solar cell film layer provided at one side of the insulating layer distant from the organic functional film layer, the amorphous silicon solar cell film layer has the same morphology as the surface of the insulating layer where the dents are provided.

First claim

What is claimed is:

1. A display panel, comprising:
a base substrate;
an organic functional film layer disposed on the base substrate;
an insulating layer disposed on the organic functional film layer, wherein the insulating layer is provided, on a side facing away from the organic functional film layer, with a plurality of pits distributed at intervals; and
an amorphous silicon solar cell film layer disposed on the side, facing away from the organic functional film layer, of the insulating layer, wherein the amorphous silicon solar cell film layer has the same morphology as a surface, provided with the pits, of the insulating layer.

2. The display panel of claim 1 , wherein the insulating layer comprises an encapsulating layer;
the encapsulating layer comprises:
at least two inorganic film layers, and
at least one organic film layer;
wherein the at least two inorganic film layers and the at least one organic film layer are stacked alternately in sequence, and
along a light emitting direction of the display panel, the organic film layer, at an outermost side of the light emitting direction, in the encapsulating layer, is provided with the plurality of pits distributed at intervals.

3. The display panel of claim 2 , wherein a depth of the pit is less than a thickness of the organic film layer.

4. The display panel of claim 1 , wherein the insulating layer comprises an encapsulating layer and a resin film layer;
the resin film layer is disposed on a side, facing away from the base substrate, of the encapsulating layer;
wherein the resin film layer is provided, on a side facing away from the encapsulating layer, with the plurality of pits distributed at intervals.

5. The display panel of claim 1 , wherein a ratio of an aperture size of the pit to a depth size of the pit is less than or equal to 1.

6. The display panel of claim 1 , wherein the pits are distributed in the insulating layer at equal intervals.

7. The display panel of claim 1 , wherein a thickness of the insulating layer is greater than 2 μm.

8. The display panel of claim 1 , wherein the amorphous silicon solar cell film layer comprises a lower electrode, a PIN film layer and an upper electrode which are stacked in sequence on the insulating layer.

9. A display device, comprising the display panel of claim 1 .

10. The display device of claim 9 , wherein the insulating layer comprises an encapsulating layer;
the encapsulating layer comprises:
at least two inorganic film layers, and
at least one organic film layer;
wherein the at least two inorganic film layers and the at least one organic film layer are stacked alternately in sequence, and
along a light emitting direction of the display panel, the organic film layer, at an outermost side of the light emitting direction, in the encapsulating layer, is provided with the plurality of pits distributed at intervals.

11. The display device of claim 10 , wherein a depth of the pit is less than a thickness of the organic film layer.

12. The display device of claim 9 , wherein the insulating layer comprises an encapsulating layer and a resin film layer; the resin film layer is disposed on a side, facing away from the base substrate, of the encapsulating layer;
wherein the resin film layer is provided, on a side facing away from the encapsulating layer, with the plurality of pits distributed at intervals.

13. The display device of claim 9 , wherein a ratio of an aperture size of the pit to a depth size of the pit is less than or equal to 1.

14. The display device of claim 9 , wherein the pits are distributed in the insulating layer at equal intervals.

15. The display device of claim 9 , wherein a thickness of the insulating layer is greater than 2 μm.

16. The display device of claim 9 , wherein the amorphous silicon solar cell film layer comprises a lower electrode, a PIN film layer and an upper electrode which are stacked in sequence on the insulating layer.

17. A method for preparing the display panel of claim 1 , comprising:
forming the organic functional film layer on the base substrate;
forming the insulating layer on the base substrate, wherein the insulating layer is provided, on the side facing away from the organic functional film layer, with the plurality of pits distributed at intervals; and
forming the amorphous silicon solar cell film layer on the side, facing away from the organic functional film layer, of the insulating layer, wherein the amorphous silicon solar cell film layer has the same morphology as the surface, provided with the pits, of the insulating layer.
