Abstract

The invention discloses a stretchable display panel and a display device, which belong to the field of display technology. The stretchable display panel includes a plurality of display islands and a plurality of stretch bridges connecting two adjacent display islands; The bottom and the second substrate, the first substrate is bonded and fixed to the second substrate through the adhesive layer, and the display island and the tensile bridge are all formed on the side of the second substrate away from the first substrate; the adhesive layer includes A plurality of adhesive blocks, the orthographic projection of the adhesive block to the light-emitting surface of the stretchable display panel and the orthographic projection of the display island to the light-emitting surface of the stretchable display panel are at least partially overlapped. The display device includes the aforementioned stretchable display panel. The present invention can make the second substrate at the position of the stretching bridge free to stretch according to its own material properties, the second substrate can be freed from the stretching of the first substrate as far as possible, and the second substrate is not easy to be stretched during the stretching process. The middle is broken, which can improve the reliability of the entire panel structure while satisfying the tensile performance.

Description

Technical field [0001] The present invention relates to the field of display, and more particularly to a stretchable display panel and a display device. Background technique [0002] With the continuous development of electronic display technology, users' requirements for electronic devices have become higher and higher. In recent years, flexible electronic equipment and tensile electronic equipment have been developed. Flexible electronic devices are devices that can be bent or folded, typically fabricated by mounting electronic devices on a flexible substrate. The stretchable electronic device is an apparatus which can be increased in one or more dimensions. A stretchable electronic device acts greatly in various applications including display devices and sensor arrays. Therefore, it is a tensile display that is one of the important development directions of the electronic device display device, which has gradually received more and more attention. [0003] The stretchable disp...
