Abstract

Embodiments of the present invention provide a stretchable display device, which solves the problem of low stretchability of stretchable display devices in the prior art. A stretchable display device provided by an embodiment of the present invention includes: an elastic substrate, a plurality of protrusions arranged on the elastic substrate, and the elastic substrate and the plurality of protrusions form a three-dimensional structure , a functional film layer superimposed on the elastic substrate provided with a plurality of protrusions, wherein the functional film layer is superimposed on the three-dimensional structure composed of the elastic substrate and the protrusions; When the display device is stretched, the protrusions on the elastic substrate are stretched, which increases the stretchability of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a stretchable display device and a preparation method thereof. Background technique [0002] With the development of display technology, various display devices have been developed, and have been widely used in TVs, personal computers, laptop computers, tablet PCs, mobile phones, curved TVs, wearable devices, and the like. In order to meet users' more demands for new functions, efforts have been made to develop new forms of display devices, such as stretchable display devices, that is, it is desired to form a display device that can extend or shrink as well as bend when it is pulled. However, when the display substrate is stretched, the pressure generated by the extension, shrinkage or bending of the substrate may make the metal wires of the substrate very likely to be stretched. Cracks or even breaks appear, that is to say, even though the display substrate is stretchable, the...
