preparation example Construction

[0069] At least one embodiment of the present disclosure provides a method for preparing a substrate. The method includes: providing a substrate, the substrate including a bendable area; forming an intermediate layer on the substrate in the bendable area; At least one signal line is formed on one side of the bottom, at least part of the signal line is formed in a curved shape, and the orthographic projection of the signal line on the substrate is in the orthographic projection of the intermediate layer on the substrate; At least one groove is formed on at least one side of the portion of the signal line (that is, at least one groove is formed in the portion of the intermediate layer that does not overlap the signal line).

[0070] In the substrate obtained by the above preparation method, at least one groove is formed in the intermediate layer. When the substrate is bent, the groove can improve the stress release ability of the intermediate layer, prevent the signal line from brea...

Abstract

Provided are a baseplate and a preparation method thereof, a display panel and a display device. The baseplate includes a substrate including a bendable region, an intermediate layer located on the substrate and in the bendable region, and at least one signal line located on one side of the intermediate layer far away from the intermediate layer, wherein an orthographic projection of the at leastone signal line on the substrate is located in an orthographic projection of the intermediate layer on the substrate, and at least part of the signal line is a curve, and at least one side of the partof the intermediate layer corresponding to the at least one signal line is provided with at least one groove. According to the technical scheme, through the groove located in the intermediate layer,the stress release capability of the intermediate layer is improved, and the signal line is prevented from breaking.

Description

Technical field [0001] At least one embodiment of the present disclosure relates to a substrate and a preparation method thereof, a display panel, and a display device. Background technique [0002] With the popularization of electronic display products, users also have higher requirements for the appearance and structure of electronic display products. Therefore, electronic display products with narrow or no borders, such as display screens, emerge as needed. A design structure of narrow-frame or borderless display can bend the non-display part of the product to the back of the display, but the bending process may cause some signal lines to break, affecting product yield and increasing production costs . Summary of the invention [0003] At least one embodiment of the present disclosure provides a substrate, including: a substrate including a bendable area; an intermediate layer located on the substrate and in the bendable area; at least one signal line located in the middle On...
