Abstract

An embodiment of the invention provides a substrate and a preparation method thereof and a display device, relates to the technical field of display, and can solve the problem of substrate deformationcaused by overlarge superimposition stress of a line recognition unit and an insulating layer. The substrate comprises a substrate body, the insulating layer and the line recognition unit, wherein the insulating layer and the line recognition unit are arranged on the substrate body. The insulating layer is provided with a groove; and at least one part of the line recognition unit is located in the groove.

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 device. Background technique [0002] Currently, the fingerprint recognition function has become an essential part of mobile phones. Among them, under-screen fingerprint recognition is a hot topic in current research. [0003] Such as figure 1 As shown, in the prior art, an optical sensor 102 is provided in the display device to enable the display device to realize the fingerprint recognition function. [0004] However, since the optical sensor 102 and the thin film transistor 101 used to control the operation of the optical sensor 102 have many stacked layers, the stress on the optical sensor 102 and the thin film transistor 101 is too large, which easily leads to deformation or even breakage of the display device. Contents of the invention [0005] Embodiments of the present invention provide a substrate, a manufact...
