具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。需要注意的是，附图中各图形的尺寸和形状不反映真实比例，目的只是示意说明本公开内容。并且自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其它实施例，都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“内”、“外”、“上”、“下”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
相关技术中，采用两层金属制作触控功能层，一层为金属网格层(Metal Mesh)，另一层为桥接层(Bridge)。金属网格位于显示区AA，并且按照横纵方向金属网格可以分为触控驱动电极和触控感应电极，其中，触控驱动电极和触控感应电极中的一个相互连接，另一个通过桥接层连接。因此无需外挂触控模组(TSP)，从而可以减小屏幕厚度，进而有利于折叠；同时没有贴合公差，可减小边框宽度。
另外，为了向触控驱动电极和触控感应电极提供有效信号，在显示区AA周围的非显示内设置了多条触控线。然而，由于空间分布限制，触控线的起始点与终止点距离不一致，会造成触控线长短不一的情况，从而导致各触控线的电阻相差很大，影响触控电学性能。在追求高精度触控性能的趋势下， 显然对触控线的布线设计提出了更高的要求。
为了至少解决相关技术中存在的上述技术问题，本公开实施例提供了一种显示基板，如图1至图6所示，可以包括：
衬底基板101，包括显示区AA、以及位于显示区AA周围的非显示区BB；
阻挡坝102，位于非显示区BB并围绕显示区AA设置；
多条触控线103，位于非显示区BB，至少部分触控线103包括导电绕线部1031，以使各条触控线103的电阻大致相同，导电绕线部1031在衬底基板101上的正投影位于阻挡坝102在衬底基板101上的正投影与显示区AA之间；
上述至少部分触控线103可以包括多条第一触控线Tx1和多条第二触控线Rx，其中，每条第一触控线Tx1的导电绕线部1031为单独绕线设置，全部第二触控线Rx的导电绕线部1031为相互嵌套绕线设置。
在本公开实施例提供的上述显示基板中，通过将每条第一触控线Tx1导电绕线部1031设置为单独绕线，全部第二触控线Rx的导电绕线部1031设置为相互嵌套绕线，使得包括多条第一触控线Tx1和多条第二触控线Rx至少部分触控线103、与其他不包括导电绕线部103的触控线103之间的电阻大致相同，即各触控线103的电阻差值在可接受的范围(例如±10％)内，因此，有效改善了各触控线103的电阻差别较大对触控的影响，利于提高触控性能。并且，本公开的导电绕线部1031设置在阻挡坝102与显示区AA之间的区域，可以将阻挡坝102内侧的空间合理利用起来，从而不需要增大非显示区BB的宽度。
需要说明的是，在本公开实施例提供的上述纹路识别基板中，由于工艺条件的限制或测量等其他因素的影响，“大致”可能会完全等同，也可能会有一些偏差，因此各特征之间“大致”的关系只要满足误差(例如上下10％的浮动)允许，均属于本公开的保护范围。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图2和图4所示，阻挡坝102可以包括环绕显示区AA的第一阻挡坝1021、以及环绕第一阻挡坝1021的第二阻挡坝1022，为了便于布线，全部导电绕线部1031在 衬底基板101上的正投影，与阻挡坝102在衬底基板101上的正投影之间的最小距离d1可以大于或等于130μm；全部导电绕线部1031在衬底基板101上的正投影与显示区AA之间的最小距离d2可以大于或等于20μm。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1至图4所示，非显示区BB可以包括：用于与触控芯片IC绑定的第一非显示区BB1；
显示基板还可以包括：位于显示区BB的多个第一触控电极104，各第一触控电极104沿第一方向Y延伸，至少部分第一触控电极104与第一触控线Tx1电连接，第一方向Y为由第一非显示区BB1指向显示区AA的方向；
第一触控线Tx1可以位于第一非显示区BB1，第一触控线BB1的导电绕线部1031与第一触控电极104电连接。
由图1和图3可以看出，在第一非显示区BB1内设置有连接第一触控电极104与触控芯片IC的第一触控线Tx1，由于相较于自第二非显示区BB2、第三非显示区BB3和第四非显示区BB4，第一非显示区BB1与触控芯片IC之间的距离最小，因此，在不对第一触控线Tx1进行绕线设计的前提下，第一触控线Tx1的长度相对较小，从而使得第一触控线Tx1的电阻相对较小。本公开中通过对第一非显示区BB1内的第一触控线Tx1设置导电绕线部1031，可以增大第一触控线Tx1的长度，从而增大第一触控线Tx1的电阻，使得第一触控线Tx1的电阻与其他触控线103的电阻大致相同，从而可以有效提高触控性能。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1和图3所示，在第二方向X上，第一触控线Tx1的导电绕线部1031的宽度可以与第一触控电极104的宽度大致相同，第二方向X与第一方向Y相互交叉，相当于在第一触控电极104的宽度范围内的第一非显示区AA1处，设置与该第一触控电极104电连接的第一触控线Tx1的导电绕线部103，这样避免了不同第一触控线Tx1的导电绕线部103之间短接的风险，利于布线设计。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1至图4所示，全部第一触控线Tx1汇聚至第一非显示区BB1的一侧(例如图1中的 右侧、图3中的左侧)；
第一触控线Tx1所含导电绕线部1031的长度，与第一触控线Tx1所含导电绕线部1031到汇聚侧(例如图1中的右侧、图3中的左侧)的距离成负相关关系，换言之，第一触控线Tx1所含导电绕线部1031到汇聚侧(例如图1中的右侧)的距离越小，第一触控线Tx1所含导电绕线部1031的长度越大，以使得第一触控线Tx1的长度基本一致、电阻基本相同。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1至图4、图7至图12所示，第一触控线Tx1还可以包括扇出引线部1032，扇出引线部1032用于连接导电绕线部1031与触控芯片IC，且扇出引线部1032位于全部第一触控线Tx1所含导电绕线部1031远离显示区AA的一侧；
扇出引线部1032包括第一错位结构F1，第一错位结构F1位于相邻导电绕线部1031之间的区域远离显示区AA的一侧，在不同导电绕线部1031的位置处，同一扇出引线部1032与相邻的第一触控线Tx1之间的距离大致相同。
由于第一触控线Tx1所含导电绕线部1031的长度不同，而较长导电绕线部1031所占布线空间大于较短导电绕线部1031所占布线空间，所以连接导电绕线部1031与触控芯片IC的扇出引线部1032需要在相邻导电绕线部1031远离显示区AA的一侧错位设置。在本公开中通过在扇出引线部1032中设置第一错位结构F1，可以实现扇出引线部1032在相邻导电绕线部1031远离显示区AA的一侧错位设置的目的，使得同一扇出引线部1032与相邻的第一触控线Tx1之间的距离大致相同。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图7至图12所示，第一错位结构F1可以为斜线段，该斜线段从相邻第一触控线Tx1所含较长的导电绕线部1031朝向相邻第一触控线Tx1所含较短的导电绕线部1031倾斜，以实现扇出引线部1032在相邻导电绕线部1031远离显示区AA的一侧错位设置的效果。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图7至图12所示，相邻导电绕线部1031之间的各第一错位结构F1的长度在远离显示 区AA的方向上可以递减或递增，以避免不同扇出引线部1032之间短接。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图5、图7至图12所示，第一触控线Tx1的导电绕线部1031可以包括依次交替连接的第一线段1031a和第二线段1031b，第一线段1031a与第二线段1032b大致沿第二方向X延伸，第一线段1031a到显示区AA的最小距离小于第二线段1032b到显示区AA的最小距离，第一线段1031a与第二线段1031b的连接处可以为直线段或弧线段。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图7至图12所示，为了便于连接第一触控电极104，与显示区AA距离最小的第一线段1031a的线宽可以大于其他第一线段1031a的线宽、及全部第二线段1031b的线宽，且其他第一线段1031a的线宽、及全部第二线段1031b的线宽可以大致相等。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1和图3所示，非显示区BB还可以包括：与第一非显示区BB1相对的第二非显示区BB2，以及连接第一非显示区BB1与第二非显示区BB2的第三非显示区BB3；
多条触控线103还可以包括多条第三触控线Tx2，多条第三触控线Tx2自第二非显示区BB2经过第三非显示区BB3延伸至第一非显示区BB1，第三触控线Tx2与第一触控电极104电连接，且第三触控线Tx2电连接的第一触控电极104与第一触控线Tx1电连接的第一触控电极104相同或不同，即可以通过第一触控线Tx1和第三触控线Tx2为相同或不同的第一触控电极104提供对应的驱动信号。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1和图3所示，受限于布线空间的大小，第三触控线Tx2在第三非显示区BB3的线宽可以大于在第一非显示区BB1的线宽且可以小于在第二非显示区BB2的线宽，换言之，针对一条第三触控线Tx2而言，其在第二非显示区BB2的线宽、在第三非显示区BB2的线宽、以及在第一非显示区BB1的线宽逐渐减小。可见，在不改变长度的情况下，可以通过合理调整第三触控线Tx2在不同非显示区 BB内的线宽，使得第三触控线Tx2的电阻与第一触控线Tx1的电阻、及第二触控线Rx的电阻大致相同。
在一些实施例中，在本公开实施例提供的上述显示基板中，为便于制作，可以设置在第一非显示区BB1，各第三触控线Tx2的线宽大致相同；在第三非显示区BB3，各第三触控线Tx2的线宽大致相同；在第二非显示区BB2，第三触控线Tx2的线宽与第三触控线Tx2电连接的第一触控电极104到第三非显示区BB3的距离成正相关关系，即第三触控线Tx2电连接的第一触控电极104到第三非显示区BB3的距离越远，该第三触控线Tx2的线宽越大。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1至图4所示，非显示区BB还可以包括：与第三非显示区BB3相对的第四非显示区BB4；
多条第二触控线Rx可以自第四非显示区BB4延伸至第一非显示区BB1，第二触控线Rx的导电绕线部1031可以位于全部第一触控线Tx1远离显示区AA的一侧，以避免第二触控线Rx与第一触控线Tx1发生短接不良。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1至图4所示，在第二方向X上，第二触控线Rx的导电绕线部1031的宽度可以与至少一个第一触控电极1031的宽度大致相同。通过将第二触控线Rx的导电绕线部1031设置在至少一个第一触控电极1031的宽度对应的第一非显示区BB1，从而可以在尽可能大的范围内设置第二触控线Rx的导电绕线部1031，利于全部第二触控线Rx的导电绕线部1031之间相互嵌套设置。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图13至图18所示，第二触控线Rx的导电绕线部1031可以包括第二错位结构F2，第二错位结构F2可以位于相邻第一触控线Tx1所含导电绕线部1031之间的区域远离显示区AA的一侧，在不同第一触控线Tx1所含导电绕线部1031的位置处，同一第二触控线Rx所含导电绕线部1031与相邻的第一触控线Tx1之间的距离大致相同。
由于第一触控线Tx1所含导电绕线部1031的长度不同，而较长导电绕线 部1031所占布线空间大于较短导电绕线部1031所占布线空间，所以位于第一触控线Tx1远离显示区AA一侧的第二触控线Rx需要在相邻第一触控线Tx1所含导电绕线部1031的位置处错位设置。在本公开中通过在第二触控线Rx所含导电绕线部1031中设置第二错位结构F2，可以实现在第二触控线Rx所含导电绕线部1031的上述错位设置目的。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图13至图18所示，第二位错结构F2可以为直线段或斜线段，直线段与第二方向X垂直，斜线段从相邻第一触控线Tx1所含较长的导电绕线部1031朝向相邻第一触控线Tx1所含较短的导电绕线部1031倾斜，以实现第二触控线Rx所含导电绕线部1031在相邻第一触控线Tx1所含导电绕线部1031远离显示区AA的一侧错位设置的效果。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图13至图18所示，相邻第一触控线Tx1所含导电绕线部1031之间的各第二位错结构F2的长度大致相同，以避免不同扇出引线部1032之间短接。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图2、图4、如图13至图18所示，第二触控线Rx所含导电绕线部1031的长度，可以与第二触控线Rx的导电绕线部1031到显示区AA的最小距离成负相关关系。也就是说，第二触控线Rx的导电绕线部1031到显示区AA的最小距离越小，第二触控线Rx所含导电绕线部1031的长度越大。这样可以使得第二触控线Rx所含较短的导电绕线部1031容易嵌入第二触控线Rx所含较长的导电绕线部1031围成的空间内。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图13至图18所示，为了便于实现第二触控线Rx与第二触控电极105的电连接，在全部第二触控线Rx的导电绕线部1031中，最外侧的导电绕线部1031的线宽，大于内嵌的其他导电绕线部1031的线宽，其他导电绕线部1031的线宽可以大致相同。
在一些实施例中，在本公开实施例提供的上述显示基板中，如图1和图3 所示，还可以包括位于显示区AA的多个第二触控电极105，第二触控电极105沿第二方向X延伸，第二方向X与第一方向Y交叉设置，第二触控电极105与第二触控线Rx电连接。
在一些实施例中，第一触控电极104可以为触控驱动电极，第二触控电极105可以为触控感应电极，或者，第一触控电极104可以为触控感应电极，第二触控电极105可以为触控驱动电极，在此不做限定。第一触控电极104和第二触控电极105可以为同层、同材料的金属网格结构，其中，同一第一触控电极104的金属网格一体设置，同一第二触控电极105的金属网格在与第一触控电极104相交的位置断开设置，并通过桥接层电连接。
