Problems solved by technology

[0004] However, the flexible display substrate includes a plurality of film layers stacked, the plurality of film layers include wiring layers, and the plurality of film layers are partially located in the bending area, and the binding area is bent to the side where the non-display surface is located. During the process, the part of the multiple film layers located in the bending area is prone to film layer separation, resulting in breakage of the signal lines of the wiring layer, and poor process of the flexible display substrate.

Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the application, not all of them. . Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] The flexible display substrate is famous for its thin thickness and bendable performance. The flexible display substrate has an opposite display surface and a non-display surface. The display surface has a display area and a non-display area. The non-display area usually includes a binding area. The binding The area is used to bind the IC to the flexible display substrate. Usually, the binding area can be bent to the side where the non-display surface is locat...

Abstract

The present application relates to a flexible display substrate, a manufacturing method thereof, and a display device, and belongs to the field of display technology. The flexible display substrate includes: a flexible base substrate and a wiring layer stacked on the flexible base substrate, a first adhesion enhancement layer and a first insulating layer, the first insulating layer is located on one side of the wiring layer, and the first The adhesion enhancement layer is located between the first insulation layer and the wiring layer, and the first adhesion enhancement layer is bonded to the first insulation layer and the wiring layer respectively; the flexible substrate has a bending area, and the first adhesion The orthographic projection of the adhesion enhancement layer on the flexible substrate is at least located in the bending area, the orthographic projection of the signal traces in the wiring layer on the flexible substrate is located in the bending area, and the first adhesion is enhanced layer is used to enhance the adhesion between the wiring layer and the first insulating layer. The present application is used to prevent the breakage of the signal wiring of the wiring layer of the flexible display substrate.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible display substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, display devices are gradually developing towards a narrow frame or even a frameless direction. Currently, display devices with narrow borders are mainly flexible display devices. [0003] The flexible display device includes a flexible display substrate. The flexible display substrate has an opposite display surface and a non-display surface. The display surface has a display area and a non-display area. The binding area bound to the flexible display substrate can be bent to the side where the non-display surface is located to achieve a narrow frame or even no frame of the display device. When the binding area is bent to the side where the non-display surface is located, the non-display The bent region of the re...
