Abstract

The disclosure relates to a display device, a stretchable display panel and a manufacturing method thereof, and relates to the field of display technology. The stretchable display panel includes a flexible substrate and a plurality of pixel islands on the flexible substrate and inter-island connections, the inter-island connections connect adjacent pixel islands; the inter-island connections include: a first outer protective layer, On the flexible substrate; the first inner protective layer is arranged on the surface of the first outer protective layer away from the flexible substrate, and the first inner protective layer is made of elastic hydrophobic material; the conductive layer is arranged on the first inner protective layer away from the flexible substrate Part of the surface; the second inner protective layer covers the conductive layer and the first inner protective layer, and the second inner protective layer is made of an elastic hydrophobic material; the second outer protective layer is located on the second inner protective layer away from the flexible substrate surface; encapsulation layer, covering the second outer protective layer; the Young's modulus of the first inner protective layer and the second inner protective layer are lower than the first outer protective layer and the second outer protective layer, the first outer protective layer and the second outer protective layer The Young's modulus of the two outer protective layers is lower than that of the encapsulation 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...
