Example Embodiment

[0021] Example 1:

[0022] Combine Figure 1-4 As shown, this embodiment provides a wiring structure, which includes a plurality of hollow units 1 connected in series, and each hollow unit 1 includes a hollow area 11 and a non-hollow area 10; wherein, any two adjacent ones The hollow area 11 of the hollow unit 1 at least partially overlaps, and the non-hollow area 10 does not overlap.

[0023] It should be noted here that the positions where the hollow areas 11 of any two adjacent hollow units 1 at least partially overlap can be formed on the same layer during preparation, that is, the two hollow units 1 are in the same layer. Of course, the two hollow units 1 can also be arranged in two layers. In this case, it is necessary to provide an insulating layer between the layers where the two hollow units 1 are located during the preparation. A via is formed at the connection position so that the two can be electrically connected later.

[0024] Since the wiring structure in this embodi...

Example Embodiment

[0034] Example 2:

[0035] This embodiment provides a display substrate, which includes a base and a wiring structure disposed on the base. The wiring structure may be any wiring structure in the first embodiment.

[0036] The display substrate in this embodiment is preferably a flexible substrate, that is, the base material used is a flexible material, such as polyimide (PI).

[0037] Since the wiring structure in the display substrate in this embodiment includes a plurality of hollowed-out units 1, during the process of bending, stretching, and twisting of the display substrate, the wiring structure can perform stress relief through the hollowed-out units 1 thereon. In order to avoid the occurrence of breakage, which may affect the failure of the device on the substrate to which the wiring structure is applied. Especially for flexible substrates, due to the nature of the flexible substrate itself, it is prone to bend. The use of the wiring structure in this embodiment can greatly ...

Example Embodiment

[0038] Example 3:

[0039] This embodiment provides a display device, which includes the display substrate in the second embodiment. Therefore, the performance of the display device of this embodiment is better.

[0040] Among them, the display device can be a liquid crystal display device or an electroluminescent display device, such as liquid crystal panels, electronic paper, OLED panels, mobile phones, tablet computers, televisions, monitors, notebook computers, digital photo frames, navigators, etc., which have display functions. Products or parts.

Abstract

The invention provides a wiring structure, a display substrate and a display device, and belongs to the technical field of display. The wiring structure comprises a plurality of hollowed units which are connected in series, and each hollowed unit comprises a hollowed area and a non-hollowed area, wherein the hollowed areas of any two adjacent hollowed units are at least partially overlapped, and the non-hollowed areas are not overlapped. Compared with a linear wiring structure, when the wiring structure is bent or stretched or warped, stress can be released through the hollowed areas of the hollowed units so as to avoid the situation that the wiring structure breaks and consequently a device on a substrate with the wiring structure fails. Besides, as the hollowed areas of any two adjacent hollowed units are at least partially overlapped, namely, the area of the connecting portion of the two hollowed units is large, it can be effectively avoided that the connecting portion of the two hollowed units breaks, and thus the yield of the wiring structure is guaranteed.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a wiring structure, a display substrate and a display device. Background technique [0002] In order to manufacture flexible display devices, many display components have been developed to use organic materials, such as organic light emitting layers, organic passivation layers, and polymer substrates (such as PI substrates) as flexible substrates. However, it is difficult to replace metal traces in displays with organic materials because the conductivity of organic materials is much lower than that of metal traces. When the flexible display device is bent, the metal traces in the display panel may be broken (its fracture strain trace is about 1%), resulting in failure of the display device. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art, and provides a wiring structure that is...
