Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Each embodiment be explained in detail.However, it will be understood by those skilled in the art that in each embodiment party of the present invention
In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details
And various changes and modifications based on the following respective embodiments, the application technical solution claimed also may be implemented.
The first embodiment of the present invention is related to a kind of flexible display substrates as shown in Figure 1, the core of present embodiment exists
In, comprising: connect between flexible substrate 1, multiple pixel islands 2 in flexible substrate and the island for connecting adjacent pixel island 2
Wiring 3；Between island connecting line 3 include: the first routing layer 31 being connect respectively with two neighboring pixel island 2 and the second routing layer 32,
And the articulamentum 33 of connection the first routing layer 31 and the second routing layer 32, wherein articulamentum 33 is stretchable conductive material layer.
By the way that connecting line 3 between island is arranged to the first routing layer 31, the second routing layer 32 and articulamentum 33, the connection of articulamentum 33 first
Routing layer 31 and the second routing layer 32, since articulamentum 33 is made of stretchable conductive material, this improves connecting lines between island
