This application is the U.S. national phase entry of PCT Application No. PCT/CN2017/109517, filed Nov. 6, 2017, which is based upon and claims priority to Chinese Patent Application No. 201710296363.8, filed on Apr. 28, 2017, the entire disclosure of which is incorporated herein by reference.
The present disclosure belongs to the field of display technologies, and specifically to a wiring structure, a display substrate and a display device.
In order to fabricate a flexible display device, many display members made of organic materials have been developed, for example, an organic light emitting layer, an organic passivation layer, and a polymer substrate (e.g., a PI substrate) serving as a flexible substrate. However, it is infeasible to replace metallic wiring in a display with organic materials because the electrical conductivity of organic materials is much lower than that of the metallic wire. When a flexible display device is being bent, the metallic wiring in the display panel may break (the ratio is about 1%), resulting in failure of the display device.
The present disclosure is intended to at least alleviate or mitigate one of the technical problems existing in the prior art, and provide a wiring structure, a display substrate and a display device that are not easily broken.
A wiring structure provided by an exemplary embodiment comprises a plurality of hollow patterns, and edges of the wiring structure along a length direction of the wiring structure extend in a straight line.
Further, in some exemplary embodiments, the wiring structure further comprises at least one bridge portion within a region where the hollow patterns are located, and the bridge portion is connected across different sides or endpoints of the hollow patterns.
In some exemplary embodiments, the plurality of hollow patterns are sequentially arranged along the length direction of the wiring structure.
In some exemplary embodiments, any adjacent hollow patterns of the plurality of hollow patterns are arranged in a staggered manner along the length direction of the wiring structure.
Alternatively, in some exemplary embodiments, any adjacent hollow patterns of the plurality of hollow patterns are arranged in a staggered manner along the length direction of the wiring structure and a direction perpendicular to the length direction of the wiring structure.
Further, in certain exemplary embodiments, any adjacent hollow patterns of the plurality of hollow patterns are symmetrical to each other.
In some exemplary embodiments, the plurality of hollow patterns comprise at least one selected from a group consisting of a triangle, a quadrangle, a hexagon, a circle and an ellipse.
In some exemplary embodiments, the material for the wiring structure comprises a metal.
A further exemplary embodiment provides a display substrate comprising a substrate and the wiring structure according to any of the above exemplary embodiments.
In some exemplary embodiments, the substrate comprises a flexible substrate.
Yet another exemplary embodiment provides a display device comprising the display substrate according to the above exemplary embodiments.
Since the wiring structure in the exemplary embodiments is provided with a plurality of hollow patterns, during the process of being bent, stretched and twisted, the wiring structure can release stress through the hollow patterns so as to avoid breakage of the wiring structure which would result in failure of devices on the substrate to which the wiring structure is applied. Particularly, for a flexible substrate, since the flexible substrate itself is prone to bending, use of the wiring structure in such embodiments can greatly improve the yield of the flexible substrate.
To enable those skilled in the art to better understand the technical solution provided by the exemplary embodiments of the disclosure, it will be further described in detail below in conjunction with the accompanying drawings and examples.
As shown in
Since the wiring structure in this exemplary embodiment is provided with a plurality of hollow patterns 10, during the process of being bent, stretched and twisted, the wiring structure can release stress through the hollow patterns 10 thereon to avoid breakage of the wiring structure that would result in failure of devices on the substrate to which the wiring structure is applied. Particularly, for a flexible substrate, since the flexible substrate itself is prone to bending, the wiring structure in this exemplary embodiment can greatly improve the yield of the flexible substrate.
In some exemplary embodiments, as shown in
In the exemplary embodiments, the shapes of the hollow patterns 10 successively disposed along the length direction of the wiring structure may be the same or different. It can be understood that the hollow patterns 10 having the same shape may facilitate the preparation of the wiring structure.
In another exemplary embodiment, as shown in
In another exemplary embodiment, as shown in
In the example shown in
In some exemplary embodiments, as shown in
In a further exemplary embodiment, the wiring structure may further comprise at least one bridge portion 12 that is located within a region where the hollow pattern 10 is located and connects different sides or endpoints of the hollow pattern 10.
Taking the wiring structure shown in
Another exemplary embodiment provides a display substrate comprising a substrate and a wiring structure on the substrate. The wiring structure may be a wiring structure as described in any of the foregoing exemplary embodiments.
The display substrate in this exemplary embodiment may be a flexible display substrate, that is, the substrate is made of a flexible material such as polyimide (PI) or the like.
Since the wiring structure in the display substrate of this exemplary embodiment is provided with a plurality of hollow patterns, during the process of being bent, stretched and twisted, stress can be released through the hollow patterns 10 so as to avoid breakage of the wiring structure which would in turn result in failure of devices on the substrate to which the wiring structure is applied. Particularly, for a flexible substrate, since the flexible substrate itself is prone to bending, usage of the wiring structure in this embodiment can greatly improve the yield of the flexible substrate.
A further exemplary embodiment provides a display device comprising the display substrate described in the foregoing exemplary embodiments. The display device may be a liquid crystal display device or an electroluminescent display device, for example, any product or component having display function such as a liquid crystal panel, an electronic paper, an OLED panel, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, and the like.
It is to be understood that the above-described embodiments are merely some exemplary embodiments for illustrating the principles of the disclosure, but the disclosure is not so limited. Various modifications and improvements can be made by those ordinarily skilled in the art without departing from the spirit and scope of the disclosure. These modifications and improvements are also considered to be within the scope of the application.
