Stretchable display substrate, manufacturing method thereof and display device

Abstract

The invention provides a stretchable display substrate, a manufacturing method thereof and a display device. The stretchable display substrate comprises a substrate body, multiple display pixel unitsdistributed in an array and multiple wires; multiple first split bands and multiple second split bands which are crossed and not mutually penetrated are distributed on the substrate body and split thesubstrate body into multiple islands arranged in an array and multiple bridges connected with all the islands; each island is at least provided with one display pixel unit; the multiple wires are electrically connected with the display pixel units; at least part of the display pixel units comprise first electrodes, second electrodes and luminescent layers, the multiple wires comprise the first wires and the second wires, the first electrodes are connected through the first wires laid on the bridges and the islands, and the second electrodes are connected through the second wires laid on the bridges and the islands. Accordingly, the problem that in the prior art, the stretchable display device adopts negative poles of the whole surface for conducting level lap joint on the screen edge, andthen potential is unstable can be solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a stretchable display substrate, a manufacturing method thereof, and a display device. Background technique [0002] The stretchable display device designed for the flexible substrate mainly completes the stretchable operation by the deformable characteristics of the flexible substrate. The flexible substrate of the stretchable display device is mainly divided into a stretchable substrate and a non-stretchable (but Deformable) substrate two structures, no matter which of the above structures is used, in order to ensure the stability of the TFT (thin film transistor) device during the stretching action of the stretchable display device, the area where the TFT device is located should be fixed. way (that is to say, the area where the TFT device is located maintains a stable shape, that is, adopts an independent island design), so as to ensure that the TFT device will not change it...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a stretchable display substrate, its manufacturing method, and a display device, which can solve the problem that the stretchable display device in the prior art adopts the entire surface of the cathode to overlap the level at the edge of the screen, resulting in unstable potential question
