Problems solved by technology

[0004] However, the back of the flexible substrate is usually provided with a back film for blocking water and oxygen. When the end of the flexible substrate is bent toward the back of the flexible substrate, the part of the back film located in the bending area of ​​the flexible substrate will generate a large bending stress. As a result, the metal wires inside the flexible substrate are prone to disconnection under the bending stress of the back film

Embodiment Construction

[0025] In order to further illustrate the flexible substrate, the manufacturing method thereof, and the display device provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0026] When a back film is provided on a flexible substrate, in order to facilitate production, the back film is usually covered on the entire back of the flexible substrate, and the back film is generally made of polyethylene terephthalate (PET) material. The back film is relatively hard, and the flexibility of the back film is relatively poor, resulting in that the back film is prone to generate a large bending stress when it is bent, causing damage to the metal wires inside the flexible substrate, resulting in disconnection of the metal wires.

[0027] Currently, in order to reduce the tensile stress required to withstand the metal lines inside the flexible substrate, see figure 1 and figure 2 , the bending stre...

Abstract

An embodiment of the invention discloses a flexible substrate, a manufacturing method thereof and a display device, relates to the technical field of display, and is used for reducing breaking risks of metal wires in the flexible substrate when the flexible substrate is bent. The flexible substrate comprises a flexible substrate body as well as a wiring layer and a back film which are arranged onthe two sides of the flexible substrate body respectively; a plane area for reserving the back film and a bending area for removing the back film are formed on one side, opposite to the wiring layer,of the flexible substrate body; a photocuring adhesive film is arranged in the bending area, elasticity modulus of the photocuring adhesive film is smaller than that of the back film. The flexible substrate, the manufacturing method thereof and the display device provided in the embodiment are applied to border narrowing of the display device.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a flexible substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous development of technology, users have increasingly diversified demands on display devices such as mobile phones and tablet computers, such as thinner and lighter, narrower bezels or ultra-narrow bezels. [0003] At present, in order to realize the narrow frame or ultra-narrow frame of the display device, a flexible substrate is usually provided in the display device, so as to take advantage of the bendable characteristics of the flexible substrate and use the flexible substrate for the end connected to the external circuit. The back of the flexible substrate is folded in half to reduce the packaging size of the flexible substrate, thereby reducing the frame size of the display device. [0004] However, the back of the flexible s...
