Description

一种显示面板和电子设备 技术领域
本申请涉及显示技术领域，更具体的涉及一种显示面板和电子设备。
背景技术
随着显示技术的不断发展，液晶显示器以及有机发光显示器等显示器件不断涌现，成为时下显示行业的主流产品，并处于日新月异的发展变革之间中，与此同时，消费者对显示器的要求也在日带提升，如超高分辨率显示、触控显示以及全面屏显示等，成为显示领域研究的热点和重要课题。
目前，实现触控功能的方案包括自容触控和互容触控两种。一般情况下，自容触控方案中通道走线的总数目为互容触控方案中的7倍左右。所以传统的自容触控方案会明显增加显示面板的边框宽度，无法适应目前的窄边框设计理念。因此，提供一种应用自容触控方案的显示面板和电子设备，对通道走线进行设计以减小通道走线在非显示区占据的空间，窄化边框是目前亟待解决的技术问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在 没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
图1为相关技术中显示面板的局部示意图。如图1所示，显示面板的显示区1包括多条触控信号线11和多个触控电极13，图中仅示意出了显示区1的一部分、以及围绕该部分显示区1的非显示区2。触控信号线11分别连接到非显示区2的触控引线12，在非显示区2所有的触控引线12构成一个扇出走线区，扇出走线区包括扇形区31和直线区32，所有的触控引线12由显示区1的边缘引出后，在直线区32收敛汇成一束沿方向e延伸的线。触控引线12包括位于扇形区31的第一子引线121和位于直线区32的第二子引线122。在扇出走线区内触控引线12密集排布，为了保证触控引线12之间相互绝缘，且最终汇聚成一束线，扇形区31在非显示区宽度方向e上需要占据一定的宽度d，宽度d较大限制了显示面板边框的窄化。基于此，本申请实施例提供了一种显示面板和电子设备，通过对非显示区内触控引线的排布方式进行设计，以减小触控引线在非显示区内占据的边框宽度。
图2为本申请实施例提供的显示面板一种可选实施方式示意图。
如图2所示的，显示面板包括：显示区1和包围显示区1的非显示区2；显示区1包括多个触控电极13组成的触控电极阵列和多条触控信号线11，一个触控电极13与至少一条触控信号线11电连接；非显示区2包括至少两个扇出走线区，至少两个扇出走线区沿非显示区2和显示区1之间的第一边界10排列。每个扇出走线区可以紧贴第一边界10，也可以与第一边界10有一定距离，具体可以根据需要设计。每个扇出走线区内均包括有多条触控引线12。需要说明的是，对于一个扇出走线区来说，扇出走线区仅为密集排布的 多条触控引线所占据的区域。触控引线12与触控信号线11一一对应电连接。各个扇出走线区内的触控引线12的数目可以相同也可以不同。图2中仅以非显示区包括两个扇出走线区进行示意。需要说明的是，本发明所有实施例中的非显示区2也可以不包围显示区1。例如，非显示区2仅在显示区1的一侧，或者仅在显示区1的相对的两侧。显示区1的任意一侧的非显示区中包括本发明实施例中的至少两个扇出走线区即可。
每个扇出走线区均包括扇形区31和直线区32，扇形区31位于第一边界10和直线区32之间；在方向e上扇形区31的宽度为d1。每条触控引线12均包括相互连接的第一子引线121和第二子引线122，第一子引线121位于扇形区31，第二子引线122位于直线区32。也即本申请中定义的扇形区31为被密集排布的多条第一子引线121占据的区域，直线区为沿着同一方向被密集排布的多条第二子引线122占据的区域。
本申请实施例中，第一子引线121的两端分别连接触控信号线11和第二子引线122，第二子引线122连接到驱动芯片的引脚(图中未示出)，从而实现在触控检测阶段，触控信号线11通过触控引线12与驱动芯片之间传递信号。触控电极阵列中的各个触控电极分别与地构成电容，当手指触摸显示面板时，手指的电容会叠加到触控电极构成的电容上，使得触控电极对地电容量产生变化，根据检测到电容变化的触控电极的位置来确定手指的触摸位置，从而实现触控功能。
位于不同的直线区32且相邻的两个第二子引线122之间的间距为第一距离H1，位于同一个直线区32且相邻的两个第二子引线122之间的间距为第二距离H2，第一距离H1大于第二距离H2。由图2中示意也可以看出，第一距离H1明显大于第二距离H2。在本申请实施例中，与触控信号线11电连接的触控引线12由第一边界10引出后，在非显示区2内分成至少两个扇出走线区进行走线，在每个扇出走线区内多条触控引线逐渐收敛汇聚成一束线。
在面板制作过程中，触控引线通常采用刻蚀工艺制作，为了保证采用同层金属制作的触控引线之间相互绝缘，相邻的两条触控引线之间的间隔距离大于等于最小的工艺间距。如果间隔距离小于最小的工艺间距的话，可能在刻蚀工艺制程中存在刻蚀不良，导致相邻的两条触控引线之间短路的现象。其中，最小的工艺间距，与触控引线所采用的材料、触控引线的厚度、刻蚀触控引线工艺中所采用的光刻胶、刻蚀液等有关。通常情况下，为了保证所有的触控引线占据的总空间最小以节省非显示区的空间，设置多条触控引线密集排布，保证相邻的触控引线之间相互绝缘，也满足最小的工艺间距。
图3为本申请实施例的原理示意图一。如图3所示，仅简化示意出显示区的触控信号线11和非显示区的触控引线，触控引线包括位于扇形区31的第一子引线121和位于直线区(未标示)的第二子引线122，图3示意的触控引线的布线方式中，扇形区31内部分第一子引线的形状为折线。在实际产品中触控引线数量非常多，为了进行原理说明仅以包括16条触控引线进行示意。其中，图3中(a)为相关技术中设置16条触控引线在一个扇出走线区内密集排布的示意图，扇形区31在方向e上占据的宽度为D1；图3中(b)为采用本申请方案后将16条触控引线设置在两个扇出走线区内分别密集排布的示意图，扇形区31在方向e上占据的宽度为D2。
在相关技术和本申请方案中，触控引线由第一边界10引出后均逐渐向中间收敛形成一束线。在图(a)和(b)采用相同制作工艺的情况下，刻蚀触控引线工艺中相邻两条触控引线之间的最小工艺间距相同。由于本申请方案(b)将16条触控引线设置在两个扇出走线区内排布，则每个扇出走线区内的触控引线的个数均小于16条，图中仅以每个扇出走线区内均包括8条触控引线进行示意。在本申请方案(b)与相关技术(a)采用相同的制作工艺时，本申请方案(b)中相邻第二子引线122之间的间距和相关技术(a)中相邻第二子引线122之间的间距相同，并且，本申请方案(b)中同一个扇 形区31内的多条第一子引线121密集排布。假设，相关技术(a)中的触控引线排布方式为触控引线之间相互绝缘，且满足最小工艺间距的情况下，制作工艺能够做到的扇形区31占据空间最小的情况。则本申请方案(b)中每一个扇出走线区内的8条触控引线的排布方式可以与相关技术(a)中扇出走线区中间的8条触控引线(图中虚线框出的55)的排布方式相同，可见本申请方案(b)中扇形区31在方向e上占据的宽度为D2小于相关技术(a)中扇形区31在方向e上占据的宽度为D1。本申请通过将非显示区内的触控引线划分在两个扇出走线区内进行走线后，能够明显减小扇形区占据的宽度，从而有利于实现边框的窄化。
图4为本申请实施例的原理示意图二。如图4所示，仅简化示意出显示区的触控信号线11和非显示区的触控引线，触控引线包括位于扇形区31的第一子引线121和位于直线区(未标示)的第二子引线122。与图3中触控引线的布线方式不同，图4中扇形区31内第一子引线121的形状均为斜线。其中，图4中(c)为相关技术中设置16条触控引线在一个扇出走线区内密集排布的示意图，扇形区31在方向e上占据的宽度为D3；图4中(g)为采用本申请方案后将16条触控引线设置在两个扇出走线区内分别密集排布的示意图，扇形区31在方向e上占据的宽度为D4。
如图4中相关技术(c)示意的，相邻两条触控信号线11之间的间距为H5，在直线区内相邻两条第二子引线122之间的间距为H6，其中，H5>H6。图4(c)还示意出了位于扇形区中心的一条中心第一子引线121-1，距离中心第一子引线121-1越远的第一子引线121与图中水平方向之间的夹角越小，而且越远离中心第一子引线121-1方向，相邻两条第一子引线121之间的间距越大。需要说明的是，如图中示意的，相邻两条第一子引线121之间的间距沿方向e逐渐变化，也就是说相邻两条第一子引线121之间存在最大间距和最小间距。所以对于最靠近扇出走线区外侧的两条第一子引线121-2和121-3来说，θ1>θ2，并且为了保证相邻的第一子引线之间相互 绝缘，且所有的第一子引线占据的总空间最小，则第一子引线121-2和第一子引线121-3之间的最小间距为最小工艺间距。
当采用本申请方案将16条触控引线设置在两个扇出走线区内排布，则每个扇出走线区内的触控引线的个数均小于16条，图4中仅以每个扇出走线区内均包括8条触控引线进行示意。假定依然与图3原理说明中相同，将每一个扇出走线区内的8条触控引线的排布方式与相关技术(c)中扇出走线区中间的8条触控引线(图中虚线框出的66)的排布方式相同，可见本申请方案(g)中虚线的示意，并不能减小扇形区在方向e上占据的宽度。这是因为，在用虚线示意的第一子引线的排布方式下，扇形区最外侧的两条虚线第一子引线之间的最小间距大于最小工艺间距，最外侧的虚线第一子引线与水平方向之间的夹角为θ3，θ3>θ2。采用本申请方案设计，且与相关技术采用相同的制作工艺时，本申请方案(g)的最小工艺间距与相关技术(c)的最小工艺间距相同。所以，本申请方案(g)的扇形区的最外侧的第一子引线与水平方向之间的夹角为θ4，设置θ4与θ2大致相等，此时能够保证扇形区的最外侧相邻的两条第一子引线之间的最小间距大约为最小工艺间距，从而相邻的第一子引线之间相互绝缘，且所有的第一子引线占据的总空间最小，此时本申请方案(g)的扇形区在方向e上占据的宽度为D4，D4<D3。本申请通过将非显示区内的触控引线划分在两个扇出走线区内进行走线后，能够明显减小扇形区占据的宽度，从而有利于实现边框的窄化。
本申请实施例将触控引线划分在至少两个扇出走线区内走线，能够减少每个扇形区内排列的触控引线的数目，在每个扇出走线区内触控引线均密集排布，保证任意相邻的两条触控引线都相互绝缘，且满足最小工艺间距保证一个扇出走线区内所有的触控引线中间的总空间最小时，能够减小扇形区占据的宽度，有利于实现边框的窄化。
需要说明的是，在图3和图4的原理说明中，给出了两种扇形 区的第一子引线的排布方式，一种排布方式为扇形区内多条第一子引线中至少部分为折线，另一种排布方式为扇形区内多条第一子引线均为斜线。对于上述两种排布方式，本申请均能够适用，在具体的实施例中仅以其中一种排布方式进行示意。
在一种实施例中，如图5所示，图5为本申请实施例提供的显示面板另一种可选实施方式示意图。非显示区2包括在沿第一边界10排列的四个扇出走线区，其中，扇出走线区为多条密集排布的触控引线占据的区域，扇形区31在方向e上占据的宽度为d2。在触控引线总数目一定的情况下，非显示区2内包括的扇出走线区个数越多，则每个扇出走线区内设置的触控引线的数目越少，相应的在每个扇形区内排列的触控引线的数目也越少，根据上述图3和图4的原理说明可以知道，每个扇形区内排列的触控引线的数目也越少，则越有利于减小扇形区在方向e上占据的宽度。在实际产品中可以根据具体的制作工艺以及设计需求，对非显示区内扇出走线区的个数进行设计，以保证能够实现边框的窄化，同时不增加制作工艺的复杂度。
本申请实施例提供的显示面板适用于液晶显示面板，也适用于有机发光显示面板，图6为图2中区域77位置处的放大示意图，图7为图6中切线333位置处一种截面示意图，图8为图6中切线333位置处另一种截面示意图。
如图6中示意出了触控信号线11与触控电极13通过过孔88连接。

在另一种实施例中，显示面板为液晶显示面板，在触控电极层之上仅设置有一层金属层走线层，所有的触控信号线均位于同一个金属走线层中，采用一个金属层来制作触控信号线，可以降低显示面板的膜层厚度，在此不再附图示意。
图8示意本申请实施例提供的显示面板为有机发光显示面板，如图8所示，显示面板包括衬底层201、以及在衬底层201之上依次排列的薄膜晶体管阵列层202、显示层205、封装层206和触控电极层107，触控电极13位于触控电极层107，金属走线层位于触控电极层107远离封装层206的一侧。其中，衬底层201可以为刚性衬底，也可以为柔性衬底；薄膜晶体管阵列层202包括多个薄膜晶体管，用于形成控制显示面板像素发光的像素电路；显示层205包括多个发光器件2051，发光器件2051包括依次堆叠的阳极4、发光层5和阴极6；封装层206用于对显示层205进行封装，以隔绝水氧，保证发光器件2051的使用寿命。可选的，封装层206包括两个 无机封装层和位于无机封装层之间的有机封装层。如图示意的，金属走线层包括第一金属走线层1081和第二金属走线层1082，图中第一金属走线层1081和第二金属走线层1082的相对位置仅作示意性表示。在相邻的金属层之间均设置有绝缘层(未标示)。其中，触控信号线中至少部分线段为降阻线段，降阻线段包括并联连接的第一子线段1111和第二子线段1112，第一子线段1111和第二子线段1112分别位于第一金属走线层1081和第二金属走线层1082。图中示意出了一条降阻线段111，第一子线段1111和第二子线段1112至少在两个位置处通过过孔相连接，第一子线段1111通过绝缘层上的过孔与触控电极13电连接。第一子线段和第二子线段并联连接构成的降阻线段能够降低电阻，也即能够降低触控信号线上的电阻，从而降低触控信号线上的压降，进而降低显示面板功耗。
在另一种实施例中，显示面板为有机发光显示面板，在触控电极层之上仅设置有一层金属层走线层，所有的触控信号线均位于同一个金属走线层中，采用一个金属层来制作触控信号线，可以降低显示面板的膜层厚度，在此不再附图示意。
本申请中触控电极层的制作材料包括金属钼、金属铝、金属钛中的一种或多种，金属走线层的制作材料包括金属钼、金属铝、金属钛中的一种或多种。可选的，触控电极层采用单层金属钼制作，或者采用钛铝钛三层金属，或者采用钼铝钼三层金属。金属走线层采用单层金属钼制作，或者采用钛铝钛三层金属，或者采用钼铝钼三层金属。
进一步的，在一种实施例中，图9为本申请实施例提供的显示面板的另一种可选实施方式局部俯视示意图。如图9所示，仅示意出了触控电极阵列中的部分触控电极13，触控电极13包括多个开口133，开口133在触控电极13厚度方向上贯穿触控电极13。其中，图中开口的形状仅作示意性表示。在有机发光显示面板中，触控电极位于显示层之上(可参见上述图8中的示意)，发光器件发出的光线需要穿透触控电极所在的膜层才能够射出显示面板，本申请实施 例通过在触控电极上设置多个开口，从而形成网格状的触控电极，发光器件发出部分光线能够由开口射出显示面板，减少了光线穿透膜层时的光损失，从而在采用金属材料制作触控电极时，触控电极不会对发光器件的出光造成遮挡，能够保证发光器件的出光效率，避免对显示面板的亮度产生影响。
可选的，各个扇出走线区中的触控引线的数目相同，在根据上述图3和图4原理说明中示意的两种排布方式进行布线时，均能够保证各个扇出走线区内的扇形区在方向e上的宽度基本相同，从而节省扇形区占据的空间，有利于实现边框的窄化。
可选的，各个扇出走线区均具有中心轴，从而实现触控引线的合理排布，保证各个扇形区在方向e上占据的宽度基本相同。
在一种实施例中，图10为本申请实施例提供的显示面板的另一种可选实施方式局部示意图，图11为图10中弯折区为弯折状态时的简化示意图。如图10所示，非显示区2还包括弯折区7，弯折区7的弯折轴71与所述第一边界10平行，第二子引线122在垂直于第一边界10的方向上贯穿弯折区7，弯折轴71为虚拟轴并非显示面板中的实体结构，弯折区7能够沿弯折轴71进行弯折。在弯折区7的远离显示区1的一侧还设置有绑定区8，绑定区8用于绑定柔性电路板，驱动芯片可以固定在柔性电路板上，从而实现驱动芯片与显示面板的连接。弯折区7能够实现弯折，如图11中示意的，绑定有驱动芯片82的柔性电路板81随弯折区弯折后，能够置于显示面板的背离显示面的一侧。在弯折区为弯折状态时，驱动芯片位于显示面板的背面而不是正面，从而进一步的窄化显示面板的边框。
在一种实施例中，图12为本申请实施例提供的显示面板的另一种可选实施方式局部示意图。图13为本申请实施例提供的显示面板的另一种可选实施方式局部示意图。如图12和图13所示的，均以非显示区2包括四个扇出走线区为例，其中，一个扇出走线区为密集排布的多条触控引线占据的区域，在每个扇出走线区外侧设置有与触控引线相邻的屏蔽信号线14。图12中示意的相邻的两个扇出 走线区之间的分别与两条位于不同扇出走线区的触控引线相邻的两条屏蔽信号线14相互连接。图13中示意出在扇出走线区外侧设置的屏蔽信号线14不与其他屏蔽信号线连接。对于屏蔽信号线的设置方式可以根据具体的工艺需要进行设定。在面板应用中，屏蔽信号线14上通入直流电压信号或者将屏蔽信号线14接地，或者屏蔽信号线14上也可以通入与触控电极相同的电压信号。屏蔽信号线14能够起到信号屏蔽的作用，有效隔绝显示面板的信号串扰。其中，屏蔽信号线14可以与驱动芯片(比如上述图10实施例中介绍到的驱动芯片)电连接，通过驱动芯片给屏蔽信号线14提供电压信号，或者屏蔽信号线14通过柔性电路板与主板电连接，由主板直接给屏蔽信号线14提供信号。
进一步的，图14为本申请实施例提供的显示面板的另一种可选实施方式简化示意图。如图14所示，在触控电极阵列包括多个触控电极行131和多个触控电极列132；每个触控电极行131包括多个触控电极13，每个所述触控电极列132包括多个触控电极13，显示区1的中心轴9与第一边界10垂直。
多条触控信号线中的至少部分为跳转触控信号线112，跳转信号线的形状为折线。为了清楚示意跳转触控信号线112的设置方式，图中仅示意出部分触控信号线为跳转触控信号线112。跳转触控信号线包括起点91和终点92，起点91与一个触控电极13电连接，终点92与第一边界10相交；起点91距显示区1的中心轴9的距离为第三距离H3，终点92距中心轴9的距离为第四距离H4，第三距离H3大于第四距离H4。如图中示意的，跳转触控信号线112延伸出显示区的位置向靠近中心轴9的方向偏移。也即，在本申请中定义的跳转触控信号线的起点为跳转触控信号线与触控电极电连接的位置点；跳转触控信号线的终点为跳转触控信号线向设置有触控引线的非显示区的方向延伸时，跳转触控信号线在显示区的终点。
在相关技术中，触控信号线的延伸方向基本与中心轴9平行，触控信号线与触控电极电连接后直接在与中心轴9平行的方向上延 伸到显示区1与非显示区2的第一边界10(如图14中虚线框出的区域99，为相关技术中触控信号线在显示区的终点的位置)，则触控信号线在显示区1的终点基本均匀分布在显示区1与非显示区2的第一边界10上，相应的触控引线与触控信号线连接位置也均分分散在第一边界10上，然后多条触控引线再逐渐收敛成一束走线，相关技术中的触控信号线的设置方式影响下边框空间的利用。而在本申请实施例中多条触控信号线中至少部分为跳转触控信号线，如图14中示意的，跳转触控信号线在显示区的终点向靠近中心轴9的方向发生偏移，则跳转触控信号线构成的扇出走线区也向中心轴9的方向靠拢，从而能够减小所有的扇出走线区在与第一边界10平行的方向上占据的总宽度，进一步节省了非显示区的空间。
在一种实施例中，图15为本申请实施例提供的显示面板的另一种可选实施方式局部示意图。如图15所示，多个触控电极列包括两个位于触控电极列边缘的边缘触控电极列1321，图中仅示意出了一个边缘触控电极列1321，其中，边缘触控电极列1321与显示区1的中心轴9平行；与至少一个边缘触控电极列1321中至少部分触控电极电连接的触控信号线为跳转触控信号线112。如图中仅示意出边缘触控电极列1321中的部分触控电极13，对于一条跳转触控信号线112来说，其起点91距显示区1的中心轴9的距离大于其终点92距中心轴9的距离。跳转触控信号线112延伸出显示区1的位置向靠近中心轴9的方向偏移，这些跳转触控信号线不需要再从图中区域20位置处引出与非显示区的触控引线相连，如图中示意的相应的触控引线12也向中心轴9方向靠拢(也可参照上述图14实施例说明进行理解)，则能够减小图中区域20位置处非显示区内设置的触控引线数目，或者边缘触控电极中触控电极电连接的触控信号线均为跳转触控信号线，在该非显示区域20内不需要设置触控引线，从而能够节省出与显示区的拐角22相邻的非显示区的空间。
进一步的，继续参考图15所示，显示区1的靠近扇出走线区3一侧的拐角22为弧形拐角。采用本申请实施例中的跳转触控信号线 的设计，能够节省出与显示区的拐角22相邻的非显示区的空间，与拐角相邻的非显示区形状的可以适应拐角的形状进行设计，则与拐角22相邻的非显示形状可以根据拐角22的形状设计成弧形形状，能够实现与显示区的弧形拐角相邻的边框区的窄化。
在一种实施例中，图16为本申请实施例提供的显示面板的另一种可选实施方式局部示意图。如图16所示，多个触控电极列包括非边缘触控电极列1322，非边缘触控电极列1322位于两个边缘触控电极列1321之间，图中局部示意图，仅示意出了一个边缘触控电极列1321，以及位于边缘触控电极列1321和显示屏的中心轴(未示出)之间的非边缘触控电极列1322；与非边缘触控电极列1322中至少部分触控电极电连接的触控信号线为跳转触控信号线112。图中示意边缘触控电极列1321和非边缘触控电极列1322均对应有跳转触控信号线112。跳转触控信号线112形状为折线，跳转触控信号线的起点距中心轴的距离大于终点距中心轴的距离，如图16中示意的，跳转触控信号线112采用折线设计时，为了保证跳转触控信号线112的中心向中心轴的方向偏移，则在显示区1内两条跳转触控信号线由于走线方向不同可能会存在交叉，如图中虚线框出的区域666内存在跳转触控信号线之间交叉的情况。当相互交叉的两条跳转触控信号线采用同一个金属层来制作时，为了实现交叉位置处两条跳转触控信号线之间相互绝缘，可以采用跨桥线的设计，设置其中一个条跳转触控信号线在交叉位置处断开，然后通过另一个金属层中的跨桥线连接断开的跳转触控信号线线。当相互交叉的两条跳转触控信号线采用不同的金属层来制作时，即使走线方向不同导致这两条跳转触控信号线交叉，但是在交叉位置处这两条跳转触控信号线仍然是绝缘的。本申请实施例能够通过对跳转触控信号线的膜层位置和排布方式进行设计，实现各个位置处的跳转触控信号线在显示区的终点向靠近中心轴的方向发生偏移，从而相应的触控引线构成的扇出走线区也向中心轴的方向靠拢，能够减小所有的扇出走线区在第一边界平行的方向上占据的总宽度，节省了非显示区的空间。
进一步的，与跳转触控信号线的起点电连接的触控电极和与其终点相邻(例如，离该终点最近，或者与该终点在垂直于面板方向上交叠但没有电性连接)的触控电极位于不同的触控电极列。具体的，可参考上述图14中的示意，与跳转触控信号线112的起点电连接的触控电极13和与跳转触控信号线112终点相邻的触控电极13之间间隔有一个触控电极列132，则跳转触控信号线的终点向中心轴9方向偏移的偏移量至少为一个触控电极列的宽度。在实际产品中，与跳转触控信号线112的起点电连接的触控电极13和与跳转触控信号线112终点相邻的触控电极13之间间隔的触控电极列的个数，可以根据具体的设计需求进行选择。
本申请实施例中，跳转触控信号线的形状为折线，跳转触控信号线至少包括第一线段，其中，第一线段与显示区的中心轴不平行，也即第一线段与中心轴垂直，或者第一线段的延长线与中心轴形成一定夹角。如图17中的示意，图17为本申请实施例提供的显示面板的另一种可选实施方式局部示意图。仅示意出部分跳转触控信号线，跳转触控信号线的形状为折线，跳转触控信号线均包括第一线段41，图中仅以第一线段41与中心轴9大致垂直进行示意。相关技术中位于显示区的触控信号线的延伸方向基本显示区的中心轴平行，而本申请实施例设置跳转触控信号线包括第一线段，第一线段能够改变跳转触控信号线在显示区内的走线方向，从而使得跳转触控信号线的终点向靠近中心轴的方向移动，并且第一线段41的长度越长，跳转触控信号线的终点向显示区中心轴方向的偏移量越大，则与该条跳转触控信号线连接的触控引线向中心轴9延长线的方向移动，从而由触控引线构成的扇出走线区也向中心轴的方向靠拢，能够减小所有的扇出走线区在第一边界平行的方向上占据的总宽度。
继续参考图17所示，跳转触控信号线112包括第一类跳转触控信号线和第二类跳转触控信号线，其中，第一类跳转触控信号线包括第一线段41、与显示区的中心轴9平行的第二线段42和第三线段43，第一线段41的两端分别连接第二线段42的一端和第三线段 43的一端，第二线段42的另一端为跳转触控信号线的起点91，第三线段43的另一端为终点92，其中，终点92为跳转触控信号线在显示区1的终点；第一类跳转触控信号线由与触控电极13电连接的位置引出后，首先在与中心轴9平行的方向走线，然后走线方向转折向靠近中心轴9的方向延伸，然后走线方向再次转折沿与中心轴9平行的方向走线延伸到显示区1和非显示区2的第一边界10。
第二类跳转触控信号线包括第一线段41、与显示区的中心轴9平行的第四线段44，第一线段41的一端为跳转触控信号线的起点91，第一线段41的另一端与第四线段44的一端电连接，第四线段44的另一端为终点92。第二类跳转触控信号线由与触控电极13电连接的位置引出后，首先向靠近中心轴9方向走线，然后走线方向发生转折，在与中心轴9平行的方向走线延伸到显示区1和非显示区2的第一边界10。
通过采用第一类跳转触控信号线或者第二类跳转触控信号线的走线方式实现触控信号线在显示区的终点的位置向靠近中心轴的方向偏移，从而与该触控信号线连接的引线也向中心轴的延长线的方向偏移，则由多条触控引线构成的扇出走线区也向中心轴的延长线靠拢，从而能够减小所有的扇出走线区在与第一边界平行的方向占据的总宽度，节省了非显示区的空间。在实际面板中可以根据具体的需求，合理的应用第一类跳转触控信号线或者第二类跳转触控信号线的走线方式，对显示区内的触控信号线进行排布设计。
实际面板中触控信号线的数量非常多，以显示区中的触控电极阵列为18*40的阵列为例，则触控电极阵列中包括18个触控电极行和40个触控电极列，相应的与一个触控电极列对应的触控信号线的数目为40条，总共的触控信号线数目为40*18＝720。在对触控信号线采用跳转走线设计时，部分的触控信号线之间可能存在交叉的情况，交叉是指两条触控信号线由于延伸方向不同均延伸到显示区的同一个位置后存在的交叉，为了避免触控信号线之间交叉短路，可以设置交叉位置处的触控信号线位于不同的金属层，或者采用跨桥 线的设计避免短路，具体可参考上述图16实施例中的说明，在此不再赘述。
在一些可选的实施方式中，跳转触控信号线的第一线段与第一边界平行，跳转触控信号线的起点距中心轴的第三距离与第一线段距第一边界的距离呈正相关。也即触控电极列距中心轴的距离越远，则与该触控电极列中的触控电极电连接的跳转触控信号线中的第一线段距第一边界的距离越远。以图17示意的显示面板进行说明，参考图中示意的跳转触控信号线112-1和跳转触控信号线112-2，跳转触控信号线112-1的起点91距中心轴9的距离大于跳转触控信号线112-2的起点91距中心轴9的距离。跳转触控信号线112-1中第一线段41距第一边界10的距离为h1，跳转触控信号线112-2中第一线段41距第一边界10的距离为h2，h1>h2。该实施方式能够简化在跳转走线区域内的触控信号线的布线方式，减小跳转触控信号线之间的交叉次数。其中，跳转走线区域即为第一线段所在区域、以及终点与第一线段之间的部分触控线段所在的区域。
在一种实施例中，触控电极阵列包括依次排列的第1触控电极列、第2触控电极列、第3触控电极列至第N触控电极列，N为正整数，其中，第1触控电极列与中心轴平行，并且第N触控电极列与中心轴的距离小于第1触控电极列与中心轴的距离；
与第n个触控电极列的多个触控电极电连接的触控信号线均为跳转触控信号线，与第n+1个触控电极列的多个触控电极电连接的触控信号线均为跳转触控信号线，且跳转触控信号线的终点与第n+2个触控电极列相邻，n为奇数，且n<N。以下以图18为例予以说明。
图18为本申请实施例提供的显示面板的局部示意图。触控电极阵列包括依次排列的第1触控电极列132-1、第2触控电极列132-2、第3触控电极列132-3、第4触控电极列132-4和第5触控电极列132-5。其中，与第1触控电极列132-1和第2触控电极列132-2中的触控电极电连接的跳转触控信号线的终点均与第3触控电极列 132-3相邻，其中跳转触控信号线的终点为跳转触控信号线与第一边界10相交的点，图中未示出，与第3触控电极列132-3和第4触控电极列132-4中的触控电极电连接的跳转触控信号线的终点均与第5触控电极列132-5相邻，以此类推。该实施方式中，对跳转触控信号线进行规律性的跳转走线设计，与第奇数个触控电极列中的触控电极连接的跳转触控信号线的终点和与第偶数个触控电极列中的触控电极连接的跳转触控信号线的终点均与同一个触控电极列相邻，规律性设计能够相对简化跳转触控信号线整体的布线方式，并且能够减少在跳转走线区域内跳转触控信号线之间的交叠次数，有利于简化制作工艺。
继续参考图18中示意的，多个触控电极行中包括相邻的第一个触控电极行131-1和第二个触控电极行131-2，且第一个触控电极行131-1与第一边界10相邻，其中，与第1触控电极列132-1和第3触控电极列132-3(也即与第n触控电极列，n为奇数)的多个触控电极13分别电连接的跳转触控信号线112中的第一线段41与第二个触控电极行131-2交叠；与第2触控电极列132-2和第4触控电极列132-4(也即与第n+1触控电极列)的多个触控电极13分别电连接的跳转触控信号线112中的第一线段41与第一个触控电极行131-1交叠。也即，与第n触控电极列中触控电极电连接的触控信号线在第二个触控电极行对应的位置开始转折向靠近显示区中心轴的方向走线，与第n+1触控电极列中触控电极电连接的触控信号线在第一个触控电极行对应的位置开始转折向靠近显示区中心轴的方向走线，仅占用显示区内第一个触控电极行和第二个触控电极行所在的区域作为跳转触控信号线的跳转走线区域，跳转走线区域占用面积小，其中，跳转走线区域即为第一线段所在区域、以及终点与第一线段之间的部分触控线段所在的区域。
另外，在跳转走线区域之外的触控信号线均可以设计成降阻线段，能够较大程度的降低各条触控信号线上电阻，进而降低功耗损失。同时如图18中示意的，跳转触控信号线112-3由与其电连接的 触控电极13引出后需要先向上拉线，然后再开始转折，本申请实施例中的方式，与第一触控电极行131-1中的触控电极电连接的跳转触控信号线向上拉线距离短，能够简化跳转触控信号线的拉线设置方式，减少跳转触控信号线之间的交叉，从而有利于简化工艺制程。
图19为图18中切线444位置处一种可选实施方式截面示意图。如图19所示，以显示面板为有机发光显示面板为例，显示面板包括位于触控电极层107远离封装层206一侧的第一金属走线层1081和第二金属走线层1082，在另一种实施例中，第一金属走线层1081和第二金属走线层1082的相对位置可以互换。图中示意，在跳转走线区域(第一个触控电极行131-1和第二个触控电极行131-2对应的位置)之外的跳转触控信号线采用降阻线段的设计，触控信号线组51中的三条跳转触控信号线在跳转转折后的走线均位于第二金属走线层1082，触控信号线组52中的三条跳转触控信号线在跳转转折后的走线均位于第一金属走线层1081。触控信号线组51中的三条触控信号线分别与同一个触控电极列中的触控电极电连接，触控信号线组52中的三条触控信号线也分别与同一个触控电极列中的触控电极电连接。该实施方式设计跳转走线区的分别与不同触控电极列中触控电极电连接的跳转触控信号线位于不同的金属走线层，从而实现合理的布线，避免跳转触控信号线交交叉导致短路。
在一种实施方式中，图20为图18中切线555位置处一种可选实施方式截面示意图，如图20所示，每条触控引线12均包括位于第一金属走线层1081的第一并联引线124和位于第二金属走线层1082的第二并联引线125，并且第一并联引线124和第二并联引线125并联连接，从而能够降低触控引线12上的电阻，降低触控信号在触控引线上传输时的压降，进一步降低功耗损失。
在另一种实施例中，位于非显示区的所有触控引线位于同一个金属层。
基于同一发明构思，本申请实施例还提供一种电子设备，图21为本申请实施例提供的电子设备示意图，如图21所示，电子设备包 括本申请任意实施例提供的显示面板100。其中，显示面板100的具体结构已经在上述实施例中进行了详细说明，此处不再赘述。当然，图21所示的电子设备仅仅为示意说明，该电子设备可以是例如手机、平板计算机、笔记本电脑、电纸书或电视机等任何具有显示功能的电子设备。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明保护的范围之内。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
