Abstract

提供一种走线结构、显示基板及显示装置。走线结构包括多个镂空图案（10），且走线结构沿走线结构的长度延伸方向延伸的两个边缘（11）均为直线。由于走线结构设置有多个镂空图案，因此，走线结构在发生弯折、拉伸、扭曲过程中，可以通过镂空图案进行应力释放，以避免走线结构、显示基板及显示装置发生断裂而影响应用该走线结构的基板上的器件失效。特别是对于柔性基板而言，由于柔性基板本身容易发生弯曲的性质，采用该走线结构可大大提高柔性基板的良率。

走线结构、显示基板及显示装置
相关申请的交叉引用
本申请要求于2017年4月28日递交的中国专利申请No.201710296363.8的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
技术领域
本公开属于显示技术领域，具体涉及一种走线结构、显示基板及显示装置。
背景技术
为了制造柔性显示装置，目前已开发出了很多由有机材料制成的显示部件，诸如有机发光层、有机钝化层和作为柔性基板的聚合物基板(如PI基板)。然而，很难用有机材料来替代显示器中的金属走线，因为有机材料的电导率远不如金属走线高。在柔性显示装置弯曲时，显示面板中的金属走线可能会断裂(其断裂应变走线约1％)，造成显示器件失效。
公开内容
本公开旨在至少缓解或减轻现有技术中存在的技术问题之一，提供一种不易断裂的走线结构、显示基板及显示装置。
根据本公开的一个实施例提供的走线结构包括多个镂空图案，且所述走线结构的沿所述走线结构的长度延伸方向延伸的两个边缘均为直线。
进一步地，在一些实施例中，所述走线结构还包括至少一个桥接部，所述桥接部处于镂空图案所在区域内，并与所述镂空图案的不同侧边或端点连接。
在一些实施例中，各个所述镂空图案沿所述走线结构的长度延伸方向顺序排列。
在一些实施例中，在沿所述走线结构的长度延伸方向上，任意相邻的所述镂空图案错位排布。
替代性地，在一些实施例中，在沿所述走线结构的长度延伸方向，以及与所述走线结构长度延伸方向垂直的方向上，任意相邻的所述镂空图案错开排布。
进一步地，任意两相邻的所述镂空图案互为对称图形。
在一些实施例汇总，镂空图案包括由三角形、四边形、六边形、圆形、椭圆形构成的组中的任意一种或多种。
在一些实施例中，所述走线结构的材料包括金属。
本公开的另一实施例提供了一种显示基板，其包括基底，以及如前述实施例中任一实施所述的走线结构。
在一些实施例中，所述基底包括柔性基底。
本公开的另外的实施例还提供了一种显示装置，其包括上述的显示基板。
由于本公开实施例中的走线结构设置有多个镂空图案，因此，走线结构在发生弯折、拉伸、扭曲过程中，可以通过镂空图案进行应力释放，以避免走线结构发生断裂，而影响应用该走线结构的基板上的器件失效。特别是对于柔性基板而言，由于柔性基板本身容易发生弯曲的特点，采用本实施例中的走线结构，可大大提高柔性基板的良率。

具体实施方式
为使本领域技术人员更好地理解本公开的实施例提供的技术方案，下面结合附图和示例对本公开作进一步详细描述。
如图1-8所示，本公开的各实施例提供一种走线结构，其包括多个镂空图案10，且走线结构的沿所述走线结构的长度延伸方向延伸的两个边缘11为直线。
由于本实施例中的走线结构上设置有多个镂空图案10，因此走线结构在发生弯折、拉伸、扭曲过程中，可以通过其上的镂空图案10进行应力释放，以避免走线结构发生断裂，而影响应用该走线结构的基板上的器件失效。特别是对于柔性基板而言，由于柔性基板本身容易发生弯曲的性质，采用本实施例中的走线结构，可大大提高柔性基板的良率。
在一些实施例中，如图1-5所示，走线结构中的各个镂空图案10沿走线结构的长度延伸方向排列。也即，沿走线结构的长度延伸方向排列的各个的镂空图案10的重心的连线处于同一条直线上。在此需要说明的，各个镂空图案10是间隔设置的，相邻的镂空图案10之间间距根据具体情况可以具体确定。
在本公开的各实施例中，沿走线结构的长度延伸方向依次设置的镂空图案10的图形可以相同，也可以不同。能够理解到的是，在设置图案相同的镂空图案10的示例中，可以方便走线结构的制备。
在本公开的另一实施例中，如图7所示，对于走线结构中的各个镂空图案10，在走线结构的长度延伸方向上，任意两相邻的所述镂空图案10错位排布，错位排布是指：将任意两相邻的所述镂空图案10中的一者沿走线结构的长度延伸方向向另一者所在的位置移动，若二者部分重叠，此时认为这两个镂空图案10之前的排布方式是错位排布的。这种错位排布也意味着任意相邻的镂空图案在走线结构的与长度延伸方向垂直的侧边上的正投影部分重叠。在该种情况下，镂空图案10的排布可包括两种情形。在一个示例中，在走线结构的长度延伸方向上，各个镂空图案10呈阶梯排布；在另一示例中，仅仅是两相邻的 镂空图案错位排布，而各奇数编号的镂空图案10的重心的连线在一条直线上，各偶数编号的镂空图案10的重心的连线在一条直线上，如图7所示。
在另一实施例中，如图8所示，对于走线结构中的各个镂空图案10，在沿所述走线结构的长度延伸方向以及与所述走线结构长度延伸方向垂直的方向上，任意两相邻的所述镂空图案10错开排布，错开排布是指：将任意两相邻的所述镂空图案10中的一者沿走线结构的长度延伸方向向另一者所在的位置移动，或者沿与长度延伸方向垂直的方向想另一者所作的位置的移动，若均不存在重叠，此时认为这两个镂空图案10之前的排布方式是错开排布的。这种错开排布也意味着任意相邻的镂空图案在走线结构的与长度延伸方向垂直的侧边上的正投影无重叠，而且它们在于长度延伸方向平行的侧边上的正投影无重叠。在该种情况下，镂空图案10的排布同样可包括两种情形。在一个示例中，在沿走线结构的长度延伸方向上，各个镂空图案10呈阶梯排布；在另一示例中，仅仅是两相邻的镂空图案10错开排布，而奇数编号的镂空图案10的重心的连线在一条直线上，偶数编号的镂空图案10的重心的连线在一条直线上，如图8所示。
在图8所示的示例中，任意两相邻的所述镂空图案10互为对称图形。这样，可以使得镂空图案10均匀的排布在走线结构中，有利于走线结构的均一性。在一个示例中，如图8所示，镂空图案10包括三角形，相邻的两个三角形的镂空图案10相对设置。在此需要说明的是，图8中只是示意性地示出两列镂空图案10，在沿走线结构的长度延伸方向上，也可以设置多列镂空图案10。
在本公开的一些实施例中，如图1-5所示，上述的镂空图案10包括三角形、四边形、六边形、圆形、椭圆形中的任意一种或多种。也即，走线结构上的各个镂空图案10的形状可以是全部相同，也可以是全部不同，也可以是部分相同。在一个示例中，走线结构上的各个镂空图案10的形状全部相同，这样可方便走线结构的制备。
在另外的实施例中，走线结构还可以包括至少一个桥接部12，桥接部12处于镂空图案10所在的区域内，并连接镂空图案10的不同的侧边或端点。
以图6所示的走线结构为例，镂空图案10包括六边形图案，在该 六边形的镂空图案10中设置有两个桥接部12，这两条桥接部12连接在六边形的镂空图案10的两条平行的侧边之间。当然，桥接部12的数量也可以为一条或者更多条，不同的桥接部12可以以彼此交叉或者相互平行方式设置在六边形的镂空图案10的区域内。本实施例中走线结构的材料可包括金属材料，此时可以使得走线结构具有良好的导电性。
本公开的另一实施例提供一种显示基板，其包括基底和设置在基底上的走线结构，该走线结构可以是如前述实施例中任一实施例所述的走线结构。
本实施例中的显示基板可以为柔性基板，也即所采用的基底的材料为柔性材料，例如聚酰亚胺(PI)等。
由于本实施例中显示基板中的走线结构上具有多个镂空图案10，因此显示基板在发生弯折、拉伸、扭曲过程中，走线结构可以通过其上的镂空图案10进行应力释放，以避免发生断裂而影响应用该走线结构的基板上的器件失效。特别是对于柔性基板而言，由于柔性基板本身容易发生弯曲的性质，采用本实施例中的走线结构，可大大提高柔性基板的良率。
本公开的另外的实施例提供了一种显示装置，其包括前述实施例所述的显示基板。显示装置可以为液晶显示装置或者电致发光显示装置，例如液晶面板、电子纸、OLED面板、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
可以理解的是，以上实施例仅仅是为了说明本发明的原理的一些示例性实施例，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
