Problems solved by technology

The structure of the wire layer from bottom to top is a substrate, a buffer layer composed of inorganic materials such as SiOx or SiN, and a metal wire for conducting the active area and the secondary active area. Above the metal wire is a layer SiOx or SiN inorganic layer, the inorganic layer below and above the metal wiring can block the external water and oxygen and protect the metal wiring. However, these continuous inorganic film layers are less flexible and easy to break during bending. These cracks will go to the metal. wire stretches, causing metal traces to break
[0006] The US patent application US20170315399 discloses a flexible OLED display device. The display device is divided into two parts: the display area and the bending area. Layers also run the risk of breaking during bending

Embodiment Construction

[0024] The specific implementation manners of the display panel provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] figure 1 It is a top view structure diagram of the first embodiment of the display panel of the present invention, figure 2 It is a schematic diagram of the side structure of the first embodiment of the display panel of the present invention. see figure 1 and figure 2 , the display panel of the present invention includes a display area DA and a bending area BA.

[0026] The display area DA refers to an area serving as a display surface of a display panel. The bending area BA refers to an area that can be bent, wherein the bending area BA can be bent relative to the display area DA. Specifically, the bending area BA can be bent toward the back of the display area DA. The back side of the display area DA refers to the side of the display panel that does not need to be displayed. In thi...

Abstract

A display panel provided by the invention has the advantages that the metal wires of a bending area are provided with the bulges extending in a second direction, and the design of the convex metal wires can effectively reduce the fracture risk and prevent the longitudinal extension of cracks.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a display panel. Background technique [0002] OLED has the advantages of fast response speed, self-illumination, high contrast, and wide temperature range. Compared with other display technologies, the biggest feature of OLED is that it can realize flexible display. Flexible display puts forward higher requirements on component manufacturing process and materials. Nowadays, full-screen mobile phones are more and more favored by consumers, and OLED flexible display technology can bend the non-display part of the component, making the display part relatively larger, thereby increasing the screen-to-body ratio of the display device. However, bending has higher requirements on the device, and long-term dynamic or static bending is likely to cause film breakage, so how to effectively avoid film breakage has become the current top priority.
