Description

显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板。
 背景技术
为实现液晶显示和触控功能的集成，在中小尺寸显示领域，一般通过将公共（Common）电极图案化，既作为液晶显示的公共电极，又作为触控功能的感应电极，通过分时作业同时驱动显示和触控功能。根据感应电极在液晶面板中的内嵌程度分为On-Cell触控技术和In-Cell触控技术。其中，In-Cell触控技术将触控功能完全内嵌到液晶像素中，因此具有整机厚度薄、显示效果优、穿透率佳等突出优点，是高端市场的首选方案。具体地，In-Cell触控技术根据工作原理不同分为互电容式触控技术和自电容式触控技术。自电容式In-Cell触控技术通过图形化方法将感应电极分割成棋盘排列的感应垫（sensor pad），每个sensor pad通过布置一根或多根触控金属引线（TP_trace）单独接出形成触控通道。TP_trace在显示面板底部集成芯片（IC）处聚集形成扇出区（TP_fanout），依次接入IC，从而实现多点触控。因此，TP_trace的完整性决定了触控功能能否完整实现。
 技术问题
在薄膜晶体管阵列基板的实际制程中，由于TP_trace通过物理气相沉积工艺在非金属膜层上形成，因此与非金属膜层间存在较大应力，导致显示面板在实际应用中极易因落摔或其他外力造成TP_fanout直线部分的TP_trace断线，造成触控功能不良。

进一步地，包括：所述凸起包括左侧凸起和右侧凸起，均匀分布于每一第一直线部的左右两侧，而且位于相邻第一直线部之间的左侧凸起和右侧凸起交错分布。
进一步地，每根触控走线还包括一第二直线部以及连接部；所述第二直线部设于所述基板的显示区，相邻第二直线部相互平行；所述连接部连接所述第一直线部以及第二直线部。

如图1以及图2所示，本发明提供一种显示面板100，包括:基板101、介电层102以及感应电极层103。
所述基板101的材料为聚酰亚胺（PI），用以实现柔性弯折。
所述介电层102设于所述基板101上。
所述介电层102包括：缓冲层1021、栅极绝缘层1022、层间绝缘层1023以及平坦化层1024。
所述缓冲层1021中设有一遮光层1025。
所述栅极绝缘层1022设于所述缓冲层1021上，所述栅极绝缘层1022中设有一有源层106。
所述层间绝缘层1023设于所述栅极绝缘层1022上，所述层间绝缘层1023中设有一第一金属层107。所述第一金属层107中包括形成薄膜晶体管的栅极线。
所述平坦化层1024设于所述层间绝缘层1023上，所述平坦化层1024中设有第二金属层108。
所述感应电极层103设于所述介电层102上。所述感应电极层103包括多个感应垫（sensor pad）。所述感应垫阵列分布。
所述介电层102具有一过孔1026，所述过孔1026向下延伸至所述触控走线1081表面，所述感应电极层103通过所述过孔1026连接所述触控走线1081。本发明对过孔1026的数量并未作出限定。
其中，所述介电层102中设有多根触控走线1081，每根触控走线1081连接所述感应电极层103。每根触控走线1081连接对应的感应垫。
至少一根触控走线1081连接所述感应垫。所述触控走线1081形成于所述第一金属层107或所述第二金属层108中。本发明优选设置于所述第二金属层108中。
每根触控走线1081还包括一第一直线部1081-1、第二直线部1081-3以及连接部1081-2。面板具有一中心线。
所述第一直线部1081-1设于所述基板101的扇出区110，所述第一直线部1081-1连接驱动IC。相邻第一直线部1081-1的相互平行，所述第一直线部1081-1的左右两侧具有多个凸起109。
所述凸起109包括左侧凸起和右侧凸起，均匀分布于每一第一直线部1081-1的左右两侧，而且位于相邻第一直线部1081-1之间的左侧凸起和右侧凸起交错分布。
进一步地，在相邻的两个第一直线部1081-1上，其中一第一直线部1081-1的左侧凸起是与另一第一直线部1081-1的右侧凸起之间的间隔位置相对应，从而形成交错结构。实际上，在同一第一直线部1081-1上，所述左侧凸起和所述右侧凸起也是交错分布，而非对称分布。
本发明第一直线部1081-1的结构，如图3所示，当触控走线1081受到剪切力时，左右两侧凸起109的对角线方向补偿面板受力形变，缓冲触控走线1081（第一直线部1081-1）所受到的应力，降低触控走线1081受力强度，避免断线。
现有技术中，无左右两侧的凸起109，在跌落或者受到其他外力时，TP_trace与非金属膜层之间存在剪切力，TP_trace受力无缓冲，无形变空间，极易发生断线。
所述第二直线部1081-3设于所述基板101的显示区，相邻第二直线部1081-3相互平行。
所述连接部1081-2连接所述第一直线部1081-1以及第二直线部1081-3，相邻的连接部1081-2相互平行。所述连接部1081-2关于中心线左右对称。
在每根触控走线1081中，所述第一直线部1081-1与所述第二直线部1081-3相互平行，所述第一直线部1081-1至所述显示面板100的中心线的距离小于所述第二直线部1081-3至所述显示面板的中心线的距离。
每根触控走线1081由于连接部1081-2的作用，在扇出区110收紧，因此所述相邻第二直线部1081-3的间距大于所述第一直线部1081-1的间距。即触控走线1081通过连接部1081-2形成一迂回走线结构，进而在扇出区110收紧，可以实现窄边框结构。
所述第二直线部1081-3的长度由所述显示面板100的中心线向左右两侧递增；所述第一直线部1081-1的长度由所述显示面板100的中心线向左右两侧递减。这样可以形成迂回结构，可以实现窄边框结构。
所述显示面板100还包括：钝化层104以及像素电极105。
所述钝化层104设于所述感应电极层103上。
所述像素电极105设于所述钝化层104上且连接所述第二金属层108。具体的，连接薄膜晶体管的源漏电极。
本发明的技术范围不仅仅局限于所述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对所述实施例进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
