Embodiment Construction

[0035] Just like the background technology, during use of the existing stretchable display panel, a large amount of heat will be generated, which will damage the display panel. The inventors have found that this is because the existing stretchable display panel generates a lot of heat during use, and in addition, the stretching action will cause the stretchable substrate to deform, further increasing the heat generation.

[0036] Such as figure 1 as shown, figure 1 It is a schematic top view structure diagram of an existing stretchable display panel when it is not stretched, and it includes a plurality of rectangular island structures 10, with a first gap 101 between the island structures 10, and two adjacent island structures The structures 10 are connected by bridge structures 11 .

[0037] Such as figure 2 as shown, figure 2 for figure 1 Shown is a schematic diagram of the top view structure of a stretchable unit in a stretchable display panel when it is stretched. W...

Abstract

The invention provides a display panel, a manufacturing method and a display device. The display panel comprises a stretchable substrate, an array layer, a light-emitting device layer and a heat dissipation unit, the stretchable substrate comprises a plurality of stretchable units, each stretchable unit comprises two island-shaped structures and a bridging structure connected with the two island-shaped structures, and the island-shaped structures are arranged on the plane where the display panel is located at intervals. An array layer is arranged on the surface of one side of the island-shapedstructure or the bridging structure, a light-emitting device layer is arranged on the surface of the side, away from the island-shaped structures, of the array layer located on the island-shaped structures, and a heat dissipation unit is arranged on the side, away from the light-emitting device layer, of the island-shaped structures or the bridging structure. Therefore, according to the scheme, heat dissipation of the island-shaped structures or the bridging structure can be achieved through the heat dissipation units, and the heat dissipation capacity of the stretchable panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a manufacturing method and a display device. Background technique [0002] Flexible display panels have become a major development trend of current display screens due to their characteristics of being bendable and easy to carry. In particular, the stretchable display panel brings a new viewing experience to users. However, during use of the stretchable display panel, a large amount of heat will be generated, thereby damaging the display panel. Contents of the invention [0003] In view of this, the present invention provides a display panel, a manufacturing method and a display device, which can improve the heat dissipation capability of the stretchable panel. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A display panel, comprising: a stretchable substrate, an array layer,...
