Background

With the continuous development of electronic display technology, flexible display devices have become a new generation of display technology with development potential due to their advantages of light weight, small thickness, flexibility, etc. The stretchable display panel has wide application prospects in the fields of biomedicine, flexible display, intelligent wearing and the like due to the extensibility.

At present, most of the mainstream stretchable display panels are formed by directly disposing a patterned and etched flexible substrate on a pre-strained elastomer, so that the flexible substrate can be directly attached to the surface of the elastomer after releasing strain.

Moreover, the structure of the display module is also destroyed after bearing the stress for many times, thereby reducing the display performance of the stretchable display panel.
