也就是说，显示区A和第一子区C2同用第一刚性基板10。第二子区C2和绑定区B共用第二刚性基板20。其中第一刚性基板10和第二刚性基板20可以是刚性的玻璃基板。柔性基板30可以是PI（聚酰亚胺）基板。
其中，弯折子区C3形成在柔性基板30上便于弯折子区C3进行弯折。另外，第一刚性基板10和第二刚性基板20在显示面板100的制程中由同一块玻璃基板切割形成。
在现有技术中，由于显示面板的显示区和下边框区（下边框区包括扇出区和绑定区）均形成在刚性的玻璃基板上，无法进行弯折，以使得下边框区的宽度过大。本实施例则将扇出区C的一部分单独取出形成在柔性基板30上，便于进行弯折，进而将绑定区B设置到显示区A的背面，缩小下边框的宽度。该部分为弯折子区C3。
请参考图4和图5，图4为本申请实施例的显示面板的显示区、第一子区、第二子区和绑定区处于平展状态时的结构示意图；图5为本申请实施例的显示面板的弯折子区处于平展状态时的结构示意图。
本实施例的显示面板100中，扇出区C包括多条扇出走线。每一扇出走线40包括设置在第一子区C1的第一部分41、设置在弯折子区C3的弯折部分43和设置在第二子区C2的第二部分42。弯折部分43电连接于第一部分41和第二部分42。第一部分41电连接于显示区A。第二部分42电连接于绑定区B。
具体的，每一第一部分41包括一第一金属走线411和连接设置在第一金属走线411一端的第一焊盘412。第一焊盘412设置在第一金属走线411远离显示区A的一端。
每一第二部分42包括一第二金属走线421和连接设置在第二金属走线421一端的第二焊盘422。第二焊盘422设置在第二金属走线421远离绑定区B的一端。
每一弯折部分43包括一第三金属走线431和分别连接设置在第三金属走线431两端的第三焊盘432和第四焊盘433。
第三焊盘432电性连接于第一焊盘412。第四焊盘433电性连接于第二焊盘422。
其中，第三焊盘432和第一焊盘412、以及第四焊盘433和第二焊盘422之间通过导电胶电性连接。
第一焊盘412、第二焊盘422、第三焊盘432和第四焊盘433与导电胶的接触面均为凹形面。这样，当第一焊盘412和第三焊盘432以及第二焊盘422和第四焊盘433之间进行配合时，便于捕获导电胶中的导电粒子及增加与导电胶的接触面积，提高第一焊盘412和第三焊盘432、第二焊盘422和第四焊盘433的稳定性。
在本实施例的显示面板100中，第三金属走线431包括走线本体4311和设置在走线本体4311上的通孔4312。通孔4312沿着走线本体4311的延伸方向间隔设置。通孔4312的设置，使得第三金属走线431在弯折时，可以释放弯折应力，提高了第三金属走线431的耐弯折性能。
其中，通孔4312之间的间距从两侧向中间逐渐递减。由于弯折子区C3在进行弯折时，第三金属走线431形成一弧状结构，使得第三金属走线431的中间部分受到的弯折应力最大，且从中间线两侧递减。因此将通孔4312之间的间距从两侧向中间逐渐递减的设置，使得第三金属走线431具有针对性的进行弯折应力的释放，进一步提高了第三金属走线431的耐弯折性能。可选的，通孔4312的形状为椭圆形、圆形和菱形中的一种。
走线本体4311的两条侧边均为曲线边。这样的设置，便于提高第三金属走线431的耐弯折性能。
本实施例的显示面板100的制备过程是：
第一，提供一刚性玻璃基板；
第二，在刚性玻璃基板上形成显示区A、扇出区C和绑定区B。即，在玻璃基板上形成整个面板的电路结构，其中包括在扇出区C和绑定区B形成完整的扇出走线和绑定电路结构；
在形成扇出走线的过程中，在刚性玻璃基板上形成扇出走线，同时在每条金属走线上形成两个焊盘，分别为第一焊盘412和第二焊盘422。第一焊盘412和第二焊盘422之间间距在500纳米~5毫米之间。
第三，柔性基板30上形成弯折子区C3；即在柔性基板30上形成多条第三金属走线431、第三焊盘432和第四焊盘433，其中每条第三金属走线431的两端分别连接一个第三焊盘412和一个第四焊盘433，且每条第三金属走线431与刚性玻璃基板上扇出走线一一对应。
第四，将显示面板中第一焊盘412和第二焊盘422之间的部分进行切割去除，其中刚性玻璃基板被分割成了三块，设置有显示区A和第一子区C1的刚性玻璃基板为第一刚性基板10，位于所述第一子区C1的扇出走线为第一部分41；设置在绑定区B和第二子区C2的刚性玻璃基板为第二刚性基板20，位于所述第二子区C2的扇出走线为第二部分42；最后一块刚性玻璃基板连通对应于其上的扇出走线被切除。
第五，将弯折子区C3中的多个第三焊盘432和第一子区C1中的多个第一焊盘412一一对应并通过导电胶绑定在一起；将弯折子区C3中的多个第四焊盘433和第二子区C2中的多个第二焊盘422一一对应并通过导电胶绑定在一起。
最后，弯折弯折子区C3，将扇出区C的第二子区C2和绑定区B弯折至显示区A的背面。
这样便完成了本申请的制备过程。
相较于现有技术的显示面板，本申请的显示面板通过在扇出区设置弯折子区，通过弯折子区的弯折将第二子区和绑定区弯折至显示区的背面，从而达到缩小边框宽度的效果；解决了现有的显示面板对边框宽度需求较大的技术问题。
以上所述，对于本领域的普通技术人员来说，可以根据本申请的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本申请后附的权利要求的保护范围。
