Abstract

The present disclosure provides a display panel and a display device. The display panel includes a substrate, including a display area and a non-display area; a display functional layer disposed on the display area; a plurality of protruding blocks disposed on the non-display area; and an encapsulation layer disposed on the display functional layer; wherein the encapsulation layer extends along an edge of the display functional layer to the non-display area and covers the plurality of protruding blocks.

First claim

What is claimed is:

1. A display panel, comprising:
a substrate comprising a display area and a non-display area;
a display functional layer disposed on the display area;
a plurality of protruding blocks disposed on the non-display area; and
an encapsulation layer disposed on the display functional layer, wherein the encapsulation layer extends along an edge of the display functional layer to the non-display area and covers the plurality of protruding blocks;
wherein surfaces of the plurality of protruding blocks toward the encapsulation layer all have a roughened structure.

2. The display panel as claimed in claim 1 , wherein the encapsulation layer comprises a first inorganic layer, an organic layer, and a second inorganic layer disposed on the display functional layer in sequence;
wherein a retaining wall is disposed on an edge region of the first inorganic layer, the organic layer is disposed on the first inorganic layer, the organic layer is blocked in the retaining wall, the organic layer is provided with the second inorganic layer covering the first inorganic layer, the organic layer, and the retaining wall, and the first inorganic layer and the second inorganic layer extend along the edge of the display functional layer to the non-display area and cover the plurality of protruding blocks.

3. The display panel as claimed in claim 2 , wherein the plurality of protruding blocks are spaced apart, a gap is formed between adjacent protruding blocks, and the first inorganic layer and the second inorganic layer extend along the edge of the display functional layer to the non-display area and cover the plurality of protruding blocks and a plurality of gaps.

4. The display panel as claimed in claim 3 , wherein each of the protruding blocks comprises a first side wall and a second side wall oppositely disposed, a third side wall and a fourth side wall disposed respectively at two sides of the first side wall, and the third side wall and the fourth side wall are oppositely disposed; and
wherein the first side wall is disposed on the substrate, and the first inorganic layer and the second inorganic layer are disposed along the second side wall, the third side wall, and the fourth side wall.

5. The display panel as claimed in claim 4 , wherein the plurality of protruding blocks are arranged in an array.

6. The display panel as claimed in claim 4 , wherein the plurality of protruding blocks comprise a plurality of first protruding blocks and a plurality of second protruding blocks;
wherein the plurality of first protruding blocks are arranged at intervals, and each of the plurality of second protruding blocks is correspondingly disposed between adjacent ones of the first protruding blocks.

7. The display panel as claimed in claim 6 , wherein a distance between the adjacent ones of first protruding blocks is equal to a distance between the adjacent ones of second protruding blocks.

8. The display panel as claimed in claim 6 , wherein a distance between the adjacent ones of first protruding blocks is greater than a distance between the adjacent ones of second protruding blocks.

9. The display panel as claimed in claim 1 , wherein the substrate comprises a first horizontal section, a second horizontal section, and a bending section disposed between the first horizontal section and the second horizontal section, the display area comprises a first display area, a second display area, and a bent display area, and the non-display area comprises a first bending area, a second bending area, and a non-bending area;
wherein the first display area is located on the first horizontal section, the second display area is located on the second horizontal section, the bent display area is located at a center of the bending section, the first bending area and the second bending area are both located on the bending section and are disposed on opposite sides of the bent display area, the non-bending area is disposed at a periphery of the first display area and the second display area, and the plurality of protruding blocks are respectively disposed on the first bending area and the second bending area.
