Problems solved by technology

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 break (its fracture strain trace is about 1%), causing the display device to fail

Embodiment 1

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

[0023] It should be noted here that the positions where the hollowed out regions 11 of any two adjacent hollowed out units 1 at least partially overlap may be structures formed on the same layer during manufacture, that is, the two hollowed out units 1 are in the same layer. Of course, the two hollow units 1 can also be arranged in two layers. In this case, an insulating layer needs to be arranged between the layers of the two hollow units 1 during preparation, and then the insulating layer and the two A via hole is formed at the connected position so that the two can be electr...

Embodiment 2

[0035] This embodiment provides a display substrate, which includes a base and a wiring structure disposed on the base, and the wiring structure may be any wiring structure in Embodiment 1.

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

[0037] Since the routing structure in the display substrate in this embodiment includes a plurality of hollowed-out units 1, the routing structure can release stress through the hollowed-out units 1 on the display substrate during bending, stretching, and twisting. In order to avoid breakage, which affects the failure of devices 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 easy to bend. Adopting the routing structure in this embodiment can greatly improve the yield of the flexible substrate.

Embodiment 3

[0039] This embodiment provides a display device, which includes the display substrate in Embodiment 2. Therefore, the performance of the display device of this embodiment is better.

[0040]Wherein, the display device can be a liquid crystal display device or an electroluminescence display device, such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a TV set, a monitor, a notebook computer, a digital photo frame, a navigator, etc. product or part.

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...
