Description

柔性基板以及显示面板 技术领域
本申请涉及显示技术领域，具体涉及一种柔性基板以及显示面板。
 背景技术
有机发光二极管（Organic Light Emitting Diode，OLED）作为一种电流型发光器件。因其具有自发光、色彩丰富、响应速度快、视角广、重量轻以及可做成柔性显示屏等优点而受到广泛关注。
随着产品的不断升级，窄边框设计成为了一种趋势。窄边框设计要求减小边缘无显示区域的宽度，尤其是下边框的宽度。目前，常用的封装方案是将柔性基板弯折到屏幕背面，实现窄边框设计。

 本发明的实施方式
请参阅图1，图1为本申请提供的柔性基板的第一种实施方式的结构示意图。
本申请提供一种柔性基板1，包括基底10、走线20以及第一过孔31。多条走线20设置在基底10上，多个第一过孔31设置在基底10上，且该第一过孔31沿走线20的延伸方向设置。
该基底10可以为柔性基底。该基底10上设置有多条走线20，多条走线20均沿着预设方向延伸，且该多条走线可以包括数据线、信号线以及电源线中的一种或多种。第一过孔31可以为长条形过孔。该第一过孔31沿着走线20的延伸方向设置。比如，该走线20的延伸方向为竖直向下，则该第一过孔31沿着竖直向下的方向设置。
需要说明的是，第一过孔31的两侧可以分别设置有一条走线20。即，第一过孔31设置在相邻走线20之间。当然，第一过孔31的两侧可以分别设置有多条走线。具体的设置方式根据实际情况而定，在此不再赘述。
在基底10上设置多个第一过孔31，并且第一过孔31沿着走线20的延伸方向设置。当柔性基板1弯折时，多个第一过孔31可以分散柔性基板1弯折时的应力，因此可以降低设置在柔性基板1上的走线20由于弯折而导致断裂的风险，从而提高了显示面板的产品良率。
请参阅图2，图2为本申请提供的柔性基板的第二种实施方式的结构示意图。本申请还提供一种柔性基板1。图2与图1的区别在于：基底10上还设置有第一凹槽501和第二凹槽502。
其中，基底10包括相对设置的第一侧11和第二侧12，以及设置在第一侧11和第二侧12之间的第三侧13和第四侧14，走线20自第一侧11至第二侧12延伸。第一凹槽501与第二凹槽502相对设置，且第一凹槽501设置在第三侧13，第二凹槽502设置在第四侧14。
在基底10的第三侧13设置第一凹槽501，以及在基底10的第四侧14设置第二凹槽502。当柔性基板1弯折时，多个第一过孔31、第一凹槽501以及第二凹槽502以分散柔性基板2弯折时的应力。因此可以降低设置在柔性基板1上的走线20由于弯折而导致断裂的风险，从而提高了显示面板的产品良率。
请继续参阅图2，第一过孔31设置在第一凹槽501和第二凹槽502之间，可以更进一步降低设置在柔性基板1上的走线20由于弯折而导致断裂的风险，从而提高了显示面板的产品良率。
请参阅图3，图3为本申请提供的柔性基板的第三种实施方式的结构示意图。本申请还提供一种柔性基板1。图3与图2的区别在于：在基底10上设置有多个第一凹槽501和多个第二凹槽502。
多个第一凹槽501间隔排布在第三侧13，多个第二凹槽502间隔排布在第四侧14。每个第一凹槽501均对应一个第二凹槽502。也即，第一凹槽501与第二凹槽502以基底10的中线为轴线对称设置。
由于在基底10的第三侧13设置多个第一凹槽501，以及在基底10的第四侧14设置多个第二凹槽502，且第一凹槽501和第二凹槽502对称设置。柔性基板1弯折时，第一凹槽501、第二凹槽502以及第一过孔31会减小柔性基板1弯折时的应力，使得柔性基板1上的走线20不会因为弯折而发生断裂，导致柔性基板1失效，进而造成显示面板失效的问题。
请参阅图4，图4为本申请提供的柔性基板的第四种实施方式的结构示意图。本申请还提供一种柔性基板1。图4的柔性基板1与图1的柔性基板1的区别在于：在基底10上还设置有第二过孔32。
其中，第一过孔31具有相对设置的第一端部311和第二端部312。在该第一过孔31的第一端部311和第二端部312均设置有第二过孔32。并且，第一过孔31与第二过孔32相连通。
例如，该第一过孔31为长条形过孔，第二过孔为圆孔。首先，可以通过如刀轮等工具在柔性基板1上开设第一过孔31。然后，在开设有第一过孔31的基础上，再在第一过孔31的第一端部311和第二端部312上开设第二过孔32，以使得第一过孔31与第二过孔32相连通。当然，第一过孔31和第二过孔32也可以一并制成。
在第一过孔31的第一端部311和第二端部312上均设置第二过孔32，可以防止第一过孔31沿着走线20的延伸方向撕裂。同时，还可以进一步降低弯折时，柔性基板1承受的应力。因此可以降低设置在柔性基板1上的走线20由于弯折而导致断裂的风险，从而提高了显示面板的产品良率。
在一种实施方式中，第二过孔32的宽度D大于第一过孔的宽度d。
请参阅图5，图5为本申请提供的柔性基板的第五种实施方式的结构示意图。本申请还提供一种柔性基板1。图5的柔性基板1与图1的柔性基板1的区别在于：多个第一过孔31设置在弯折区101外。
其中，基底10具有一弯折区101，多个第一过孔31设置在弯折区101外，且分布在弯折区101两侧。将多个第一过孔31设置在弯折区101外，可以减小柔性基板1弯折时所产生的应力，可以降低设置在柔性基板1上的走线20由于弯折而导致断裂的风险。
在一种实施方式中，设置在弯折区101一侧的第一过孔31与设置在弯折区101另一侧的第一过孔31以弯折区101为轴对称，如图5所示。
请参阅图6，图6为本申请提供的柔性基板的第六种实施方式的结构示意图，本申请还提供一种柔性基板1。图6的柔性基板1与图5的柔性基板1的区别在于：第一过孔31的两端均设置有第三过孔33，且设置在弯折区101一侧的第一过孔31通过第三过孔33与设置在弯折区101另一侧的第一过孔31相连通。
请参阅图7，图7为本申请提供的柔性基板的第七种实施方式的结构示意图。
本申请提供一种柔性基板1，包括基底10、走线20以及第一凹槽503。其中，多条走线20设置在基底10上，多个第一凹槽503设置在基底10上，且该第一凹槽503沿走线20的延伸方向设置。
需要说明的是，图7的柔性基板1与前面实施例任一个柔性基板1的区别在于：图7的柔性基板1是在基底10上设置多个第三凹槽503。该凹槽503的设置方式与前面实施例的相同，在此不再赘述。
相应的，本申请还提供了一种显示面板。该显示面板包括柔性基板1。柔性基板1具体的设置方法请参阅前面实施例，在此不再赘述。
以上对本申请实施例提供的柔性基板以及显示面板进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
