Abstract

The invention discloses a display substrate, a preparation method thereof and a display device. The preparation method of the display substrate comprises the steps that a flexible substrate is formedon a hard substrate, and the flexible substrate is provided with an open hole in an open hole region; the open hole is filled with a soluble organic material; a pixel island structure located in a pixel island region and a connecting bridge structure located in a connecting bridge region are prepared on the flexible substrate; the hard substrate and the display substrate are separated; and a solvent is used for treating the organic material so as to remove the organic material. In the process of preparing the display substrate by the adoption of the method, tensile fracture caused by the openhole region to the pixel island region and the connecting bridge region in the separating process of the hard substrate and the display substrate is reduced, damage to the display substrate is avoided, and the yield of the display substrate is increased; and meanwhile, in the production process of a flat layer, exposure and etching difficulty is lowered, production cost is lowered, and the production difficulty of the display substrate is lowered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] Stretchable displays are display devices that can be stretched to a certain extent while maintaining image quality. Stretchable display devices can be used in fitness trackers, wearable devices, Internet of Things devices, automobiles and artificial intelligence. fields. [0003] There are many ways to prepare stretchable display devices. At present, the commonly used stretchable display devices mainly include shrinkage and opening methods. Shrinkage is the shrinkage of the substrate to achieve stretchability through the shrinkage characteristics of the substrate. The hole-type stretchable display device includes a pixel island region, a connection bridge region and an opening region, the hole region is located between the pixel island regions, and adjacent pixel island regio...
