Abstract

The invention relates to a display device, a stretchable display panel and a manufacturing method of the display panel, and relates to the technical field of display. The stretchable display panel comprises a flexible substrate and a plurality of pixel islands and island connection lines on the flexible substrate, wherein the island connection lines connect the adjacent pixel islands; each islandconnection line comprises a first outer protective layer arranged on the flexible substrate, a first inner protective layer arranged on the surface, deviating from the flexible substrate, of the firstouter protective layer and made of an elastic hydrophobic material, a conductive layer arranged at the local part of the surface, deviating from the flexible substrate, of the first inner protectivelayer, a second inner protective layer covering the conductive layer and the first inner protective layer and made of the elastic hydrophobic material, a second outer protective layer arranged on thesurface, deviating from the flexible substrate, of the second inner protective layer, and a packaging layer covering the second outer protective layer; the Young moduli of the first inner protective layer and the second inner protective layer are lower than the Young moduli of the first outer protective layer and the second outer protective layer; and the Young moduli of the first outer protectivelayer and the second outer protective layer are lower than that of the packaging layer.

Description

technical field

[0001] The present disclosure relates to the field of display technology, in particular, to a display device, a stretchable display panel, and a method for manufacturing a stretchable display panel. Background technique

[0002] At present, the stretchable display panel has received extensive attention. It generally includes a plurality of pixel islands, each pixel island includes a plurality of pixels, and the pixel islands are connected by connecting lines between the islands. Since the pixel islands are hollow structures, Thus stretching is possible. However, for the existing stretchable display panel, during the stretching process, the inter-island connection is prone to stress concentration, and cracks or even breakage may occur, thereby affecting normal display.

[0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may...
