Problems solved by technology

[0005] An embodiment of the present invention provides a flexible display panel, which is used to solve the problem of the flexible display panel in the prior art. Due to the large Young's modulus of the flexible substrate in the bending area, the neutral layer in the bending area is formed on the metal wiring. When the panel is bent, the metal wiring is easily damaged by stress and the circuit breaks, which leads to the technical problem of poor display of the panel

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0029] In the flexible display device, due to the flexible display panel in the prior art, the Young's modulus of the flexible substrate in the bending area is relatively large, so that the neutral layer in the bending area is formed under the metal wiring layer, resulting in When the panel is bent, the metal traces are easily damaged by stress and cause circuit breakage, resulting in poor display of the panel. This embodiment can solve this defect.

Abstract

The invention provides a flexible display panel. A bending section is arranged at a non-display area of the flexible display panel, the bending section comprises a flexible substrate, an insulating layer arranged on the flexible substrate, a metal wiring layer arranged on the insulating layer, and a flat layer covering the metal wiring layer, wherein a groove for thinning the flexible substrate atthe bending section is formed in the surface of the flexible substrate. The flexible display panel provided by the invention has the advantages of entirely thinning the flexible substrate at the bending section so as to adjust a neutral layer to the metal wiring layer, and the technical effects of reducing the line loss and avoiding the bad display at a panel display area can be reached.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel and a display device. Background technique [0002] With the development of science and technology, people's requirements for products are getting higher and higher. Full-screen and borderless products can enable users to obtain a better experience, and increasing the screen ratio has become the goal pursued by the display market. The screen-to-body ratio is the most effective technical method. However, there are many metal traces in the bending area of ​​the display panel. The small bending radius of the bending area makes the metal traces more susceptible to stress damage and breakage, which in turn leads to the display of the panel. The area is bad. [0003] For example Figure 1a As shown, the metal wiring layer 102 in the bending area 101 of the flexible display panel in the prior art is a metal wire with a specific shape processed above th...
