Abstract

The invention discloses a substrate. The substrate comprises a flexible substrate, an array function layer arranged above the flexible substrate and a back plate arranged on the side, away from the array function layer, of the flexible substrate. At least one groove is formed in one side, far away from the flexible substrate, of the back plate; according to the embodiment of the invention, the back plate is arranged at one side, far away from the array function layer, of the flexible substrate; the back plate is used for protecting the flexible substrate, at least one groove is formed in the side, away from the flexible substrate, of the back plate and can be used for releasing stress generated in the bending process of the substrate, and therefore, the substrate can be bent with larger curvature, and the curvature radius of the substrate is effectively reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a substrate, a preparation method thereof, and a display panel. Background technique [0002] Smart terminal devices (such as smart phones, tablet computers, etc.) have been developing towards a larger display area, that is, a larger display screen, and a thinner, lighter, and more portable direction. At present, smart terminal devices, especially mobile phones, with the wide application of borderless technology, their screen-to-body ratio has approached the limit. As a result, larger screens require larger carrying volumes. Therefore, as solutions that can provide larger display screens and smaller carrying volumes, the emergence and application of foldable display screens and rollable display screens is an inevitable result of demand. Compared with the folding method of the display screen of smart terminal equipment, the curling and retracting method of the display screen has...
