在示例性实施方式中，显示结构层包括发光区域和非发光区域。如图6所示，由于有机发光层是在像素定义层所限定的像素开口区域出射光线，因而像素开口区域为发光区域P1，像素开口以外区域为非发光区域P2，非发光区域P2位于发光区域P1的外围。本公开示例性实施例中，将每个发光区域P1称为子像素(sub pixel)，如红色子像素、蓝色子像素或绿色子像素，每个不发光区域P2称为子像素边界，如红色子像素与绿色子像素之间的红绿子像素边界、蓝色子像素与绿色子像素之间的蓝绿子像素边界。这样，显示结构层的发光区域包括周期性排布的多个子像素，显示结构层的非发光区域包括位于相邻子像素之间的子像素边界。
图7-1到图7-3为本公开示例性实施例显示面板的结构示意图。显示面板包括在基底上叠设的显示结构层700和触控结构层800。在本示例中，显 示结构层700包括周期性排布的第一子像素、第二子像素、第三子像素和第四子像素，4个正方形状的子像素以正方形方式排列，如图7-1所示。图7-1示意了20个子像素行和20个子像素列，形成20*20个子像素701，位于相邻子像素行之间的多条子像素水平边界702，以及位于相邻子像素列之间的多条子像素竖直边界703，子像素水平边界702沿着水平方向延伸，子像素竖直边界703沿着竖直方向延伸。在本示例中，触控结构层800包括周期性排布的第一网格图案、第二网格图案、第三网格图案和第四网格图案，第一网格图案的形状与第一子像素的形状可以相同，第二网格图案的形状与第二子像素的形状可以相同，第三网格图案的形状与第三子像素的形状可以相同，第四网格图案的形状与第四子像素的形状可以相同，如图7-2所示。图7-2示意了20个网格行和20个网格列，形成20*20个网格图案801，20*20个网格图案801由多条水平金属线802和多条竖直金属线803垂直交叉构成。在示例性实施方式中，20*20个网格图案可以称为一个重复单元。图7-3示意了触控结构层800设置在显示结构层700上的示意图。如图7-3所述，将触控结构层设置在显示结构层上后，触控结构层800中20*20个网格图案801与显示结构层700中20*20个子像素701的位置相对应，即第一网格图案的位置与第一子像素的位置相对应，第二网格图案的位置与第二子像素的位置相对应，第三网格图案的位置与第三子像素的位置相对应，第四网格图案的位置与第四子像素的位置相对应。触控结构层800中多条水平金属线802与显示结构层700中多条子像素水平边界702的位置相对应，触控结构层800中多条竖直金属线803与显示结构层700中多条子像素竖直边界703的位置相对应，子像素水平边界702在基底上的正投影包含水平金属线802在基底上的正投影，子像素竖直边界703在基底上的正投影包含竖直金属线803在基底上的正投影。这样，金属线在基底上的正投影所围成的区域包含至少一个子像素在基底上的正投影。本公开示例性实施例中，“A的正投影包含B的正投影”即是“B的正投影位于A的正投影的范围内”，是指B的正投影的边界落入A的正投影范围内，或者A的正投影的边界等于B的正投影的边界。这样形成的显示面板中，触控结构层800中的金属线均位于显示结构层700中不发光的子像素边界区域，金属线没有穿越出射光线的发光区域，当显示面板在显示暗画面或者在外部环境光线强烈时，金属网格不会被肉眼观 察到，不会影响显示效果。在一些可能的实现方式中，网格图案的形状可以不同于子像素的形状，本公开在此不做限定。
在示例性实施方式中，触控结构层800的多个网格图案上设置有多个切口，多个切口将网格图案的金属线断开，使触控结构层800形成触控区、边界区和连接桥区。如图7-3所示，图中无颜色填充位置的子像素701所对应的网格图案为触控区，深色填充位置的子像素701所对应的网格图案为边界区，边界区为X形状，X形状中部的重叠区域为连接桥区。触控区包括第一触控电极和第二触控电极，边界区设置在相邻的第一触控电极与第二触控电极之间，边界区的多个网格图案中设置有多个切口，切口截断网格图案的金属线，使得相邻的第一触控电极和第二触控电极绝缘。被X形状边界区隔开的四个触控区中，上触控区和下触控区可以是第一触控电极，左触控区和右触控区是第二触控电极，或者，上触控区和下触控区可以是第二触控电极，左触控区和右触控区是第一触控电极。
图8-1到图8-4为几种触控区、边界区和连接桥区的示意图，示意了一个重复单元内触控区、边界区和连接桥区的形状，实线表示边界区，虚线表示连接桥区。在示例性实施方式中，触控区的形状可以是三角形，边界区的形状为X形，如图8-1所示。或者，触控区的形状可以是矩形，边界区的形状为#形，如图8-2所示。或者，触控区的形状可以是菱形，边界区的形状为菱形，如图8-3所示。或者，触控区的形状可以是六边形，边界区的形状为六边形，如图8-4所示。在一些可能的实现方式中，触控区的形状可以是三角形、正方形、矩形、菱形、梯形、平行四边形、五边形和六边形中的任意一种或更多种，边界区的形状可以是X形、#形、十字形、正方形、矩形、菱形、平行四边形和六边形中的任意一种或更多种，本公开在此不做具体的限定。
在示例性实施方式中，触控结构层金属网格由多个重复单元拼接而成，重复单元是构成触控结构层金属网格的基本单元，通过重复且沿着某一方向连续设置重复单元，可以构成触控结构层金属网格。每个重复单元包括多个网格图案，多个网格图案上设置有多个切口。在示例性实施方式中，重复单元可以包括5*5个网格图案到25*35个网格图案。在一些可能的实现方式中， 考虑到设计过程中设计人员的设计便捷性及变更灵活性，采用重复排列方式进行重复单元排列设计中，重复排列的重复单元可以包括基本的重复单元、镜像的重复单元、反转的重复单元、旋转的重复单元中的任意一种或多种，本公开在此不做限定。
当触控结构层和显示结构层叠合后，触控结构层的触控区会出现水印(mura)缺陷，水印缺陷具体表现为暗态下的点状、线状或块状印记，亮态下的不同方位角的亮度衰减差异。图9-1到图9-2为触控区水印缺陷的示意图。图9-1示意了触控区内9*6个网格图案中切口的设置情况，通过多个切口将金属线切断，隔离出相应的区域，在触控区内形成虚拟区。但这种切口设置使得触控区的水印缺陷比较明显，会被肉眼观察到，如图9-2所示。
图10为本公开示例性实施例一种重复单元的示意图，重复单元包括9*6个六边形的网格图案。如图10所述，在水平方向和竖直方向，重复单元分别具有第一特征长度S1和第二特征长度S2。在示例性实施方式中，第一特征长度S1大于或等于第二特征长度S2，第一特征长度S1称为重复单元的最大特征长度S，即最大特征长度S是第一特征长度S1和第二特征长度S2中的最大值。在示例性实施方式中，重复单元的最大特征长度S为0.2mm到1.2mm，以使得观看者眼睛1度范围内的空间频率大于或等于10。
图11为观看者眼睛1度范围内的空间频率的示意图。通常，眼睛的空间分辨能力(即视力)用可分辨视角(degree)的倒数为单位，正常人眼睛的最小可辨视觉阀值约0.5，最大视觉范围200度(宽)×135度(高)。观看者眼睛1度范围内的空间频率(Cycle/Degree，简称CPD)，表示眼球每转动一度扫过的黑白条纹周期数。如图11所示，观看者眼睛1度范围内的空间频率CPD与观看者眼睛到显示屏的距离L和条纹周期h有关，计算公式为：
CPD＝1/(57.3*arctan(h/L))
对给定的条纹周期h，观看者眼睛到显示屏的距离L越大，观看者眼睛1度范围内的空间频率CPD越大。对于给定的观看者眼睛到显示屏的距离L，条纹周期h越小，观看者眼睛1度范围内的空间频率CPD越大。研究表明，对于由多个重复单元重复拼接而成的触控结构层，多个重复单元会形成明暗条纹，明暗条纹的条纹周期h即是重复单元的最大特征长度S，因而观看者 眼睛1度范围内的空间频率CPD＝1/(57.3*arctan(S/L))，则有：
S＝L*tan(1/(57.3*CPD))
在示例性实施方式中，观看者眼睛到显示屏的距离L为100mm到1000mm，CPD≥10，，所述重复单元的最大特征长度为所述重复单元某一方向的最大尺寸，1/(57.3*CPD)为弧度值。
在观看者观看触控结构层时，观看者眼睛到显示屏的距离L可以分为近观看距离和远观看距离两类，近观看距离是针对小尺寸显示屏，远观看距离是针对大尺寸显示屏。在示例性实施方式中，近观看距离中，观看者眼睛到显示屏的距离L可以为100mm到400mm，远观看距离中，观看者眼睛到显示屏的距离L可以为400mm到1000mm。
在示例性实施方式中，针对近观看距离，设置重复单元的最大特征长度S为0.2mm到0.4mm。在一些可能的实现方式中，设置重复单元的最大特征长度S为0.25mm到0.35mm。
在示例性实施方式中，针对远观看距离，设置重复单元的最大特征长度S为0.4mm到1.2mm。在一些可能的实现方式中，设置重复单元的最大特征长度S为0.5mm到1.0mm。
在一些可能的实现方式中，设置重复单元的最大特征长度S使得观看者眼睛1度范围内的空间频率CPD大于或等于30。
触控结构层的金属网格是由多个重复单元重复拼接而成，多个重复单元会形成明暗条纹，本公开示例性实施例通过设置重复单元的最大特征长度，增大了观看者眼睛1度范围内的空间频率，降低了观看者分辨明暗条纹的敏感度，能够规避不同方位角下的水印，降低水印的可见性。
图12-1到图12-3为几种重复单元形状的示意图。重复单元包括多个网格图案，网格图案是由金属线构成的多边形。在示例性实施方式中，重复单元的形状可以为正方形，沿着水平方向连续设置，正方形的边长为最大特征长度S，如图12-1所示。或者，重复单元的形状可以为长方形，沿着水平方向连续设置，长方形长边的边长为最大特征长度S，如图12-2所示。或者，重复单元的形状可以为六边形，沿着水平方向连续设置，六边形水平方向顶 角间的最大距离为最大特征长度S，如图12-3所示。在一些可能的实现方式中，重复单元的形状可以包括三角形、正方形、矩形、菱形、梯形、五边形和六边形中的任意一种或多种，本公开在此不做限定。
在示例性实施方式中，在触控区、边界区和连接桥区设置切口时，按照切口之间的相对位置，切口可以包括孤立切口、连续切口和拐角切口中的任意一种或多种。按照切口方向，切口可以包括第一方向切口、第二方向切口和第三方向切口中的任意一种或多种。按照切口与子像素的位置关系，切口可以包括第一切口、第二切口和第三切口中的任意一种或多种。
在示例性实施方式中，当一个方向上存在多个切口连续设置时，一个方向上连续切口中切口的个数小于或等于3个。图13-1到图13-2为本公开示例性实施例连续切口的示意图，图中黑色块表示切口，切口可以理解为切割金属线的假想线，虚线表示切割假想线的方向。本文中，一个多边形的网格图案至少包括两个相互平行的第一边和两个相互平行的第二边，第一边与第二边不平行。“连续切口”是指，在第一方向上连续设置的至少一个网格图案中每个网格图案的两个第一边上均设置有切口，第一方向与每个网格图案的第一边交叉。或者，在第二方向上连续设置的至少一个网格图案中每个网格图案的两个第二边上均设置有切口，所述第二方向与每个网格图案的第二边交叉。或者说，一个多边形的子像素至少包括两个相互平行的第一侧边，两个相互平行的第一侧边上的金属线均设置有切口，则两个第一侧边上的金属线的切口是连续切口，子像素具有连续切口。子像素侧边上的金属线是指位于子像素边界所在区域的金属线，子像素是指发光区域，子像素边界是指子像素周围的非发光区域。“孤立切口”是指，一个多边形的网格图案只有一条边上设置有切口，则网格图案具有孤立切口。或者，一个子像素只有一个侧边上的金属线设置有切口，则子像素具有孤立切口。本文中，“平行”是指两条直线形成的角度为-10°以上且10°以下的状态，“垂直”是指两条直线形成的角度为80°以上且100°以下的状态。
如图13-1所示，可以采用网格图案来说明连续切口和孤立切口。对于第一网格行、第二网格列对应的网格图案，该网格图案左侧的第一边(金属线)上设置有一个切口，右侧的第一边(金属线)上设置有另一个切口，左侧的 第一边和右侧的第一边平行，则两个切口属于连续切口，且连续切口中切口的个数为2。如果行方向上一个邻近的网格图案也具有连续切口，则行方向上连续切口中切口的个数为3。对于第三网格行、第二网格列对应的网格图案以及第三网格行、第三网格列对应的网格图案，网格图案只有一个边上设置有切口，则该切口属于孤立切口。
如图13-1所示，可以采用子像素来说明连续切口和孤立切口。对于第一网格行、第二网格列对应的B子像素，该B子像素左侧侧边的子像素边界区域内的金属线上设置有一个切口，右侧侧边的子像素边界区域内的金属线上设置有另一个切口，左侧侧边和右侧侧边相互平行，则两个切口属于连续切口，且连续切口中切口的个数为2。如果左侧方向上与B子像素邻近的G子像素的左侧侧边和右侧侧边的金属线上均设置有切口，则该方向上连续切口中切口的个数为3。对于第二网格行、第六网格列对应的G子像素，该G子像素上侧侧边的子像素边界区域内的金属线上设置有一个切口，下侧侧边的子像素边界区域内的金属线上设置有另一个切口，上侧侧边和下侧侧边相互平行，则两个切口属于连续切口，且连续切口中切口的个数为2。如果下侧方向上与G子像素邻近的B子像素的上侧侧边和下侧侧边的金属线上均设置有切口，则该方向上连续切口中切口的个数为3。对于第三网格行、第二网格列对应的B子像素以及第三网格行、第三网格列对应的G子像素，B子像素只有右侧侧边的子像素边界区域内的金属线上设置有一个切口，G子像素只有左侧侧边的子像素边界区域内的金属线上设置有一个切口，则B子像素与G子像素之间的切口属于孤立切口。
如图13-2所示，一个连续切口是水平方向，连续切口中切口的个数为3，另二个连续切口是倾斜方向，连续切口中切口的个数为3。倾斜方向包括左上方向和右上方向，或者包括右下方向和左下方向。
在示例性实施方式中，对于拐角切口，当拐角切口在第一方向或第二方向上存在连续切口时，连续切口中切口的个数小于或等于2个。图14-1到图14-2为本公开示例性实施例拐角切口的示意图。本文中，“拐角切口”是指，一个多边形的网格图案的一个第一边和一个第二边均设置有切口，则该两个切口是拐角切口，网格图案具有拐角切口，相当于网格图案两个边的切口方 向发生了折转。或者说，一个多边形的子像素至少包括不平行的第一侧边和第二侧边，两个不平行的第一侧边和第二侧边上的金属线均设置有切口，则两个切口是拐角切口，相当于子像素两个侧边的切口方向发生了折转。
如图14-1所示，可以采用网格图案来说明拐角切口。对于第一网格行、第三网格列对应的网格图案，该网格图案左侧方向的第一边上设置有一个切口，下侧方向的第二边上设置有另一个切口，第一边与第二边不平行，则该两个切口是拐角切口，拐角切口的方向分别是左侧方向和下侧方向。第一网格行、第二网格列对应的网格图案是与第一边邻近的网格图案，该网格图案具有连续切口，则拐角切口左侧方向上包括连续切口，且连续切口中切口的个数为2个。第二网格行、第三网格列对应的网格图案是与第一边邻近的网格图案，该网格图案具有连续切口，则拐角切口下侧方向上包括连续切口，且连续切口中切口的个数为2个。
如图14-1所示，可以采用子像素来说明拐角切口。对于第一网格行、第三网格列对应的G子像素，该G子像素左侧侧边的子像素边界区域内的金属线上设置有向左侧方向延伸的一个切口，下侧侧边的子像素边界区域内的金属线上设置有向下侧方向延伸的另一个切口，则向左侧方向延伸的切口和向下侧方向延伸的切口形成拐角切口，拐角切口的方向分别是左侧方向和下侧方向。当左侧方向与该G子像素邻近的B子像素具有连续切口时，则拐角切口左侧方向上包括连续切口，且连续切口中切口的个数为2个。当下侧方向与该G子像素邻近的R子像素具有连续切口时，则拐角切口下侧方向上包括连续切口，且连续切口中切口的个数为2个。
如图14-2所示，一个拐角切口分别是左侧方向和右下侧方向，两个方向均包括连续切口，连续切口中切口的个数为2。另一个拐角切口分别是右侧方向和左下侧方向，左下侧方向包括连续切口，连续切口中切口的个数为2。
在示例性实施方式中，当多个拐角切口连续设置时，多个拐角构成开放图形。图15-1到图15-2为本公开示例性实施例开放图形的示意图。如图15-1所示，第一网格行、第三网格列对应的G子像素处形成一个拐角切口，该拐角切口的一个端部是第一网格行、第一网格列对应的G子像素。第三网格行、第三网格列对应的G子像素处形成另一个拐角切口，该拐角切口的一个端部 是第三网格行、第一网格列对应的G子像素。由于两个拐角切口的端部没有重叠，因而两个拐角切口所形成的图形是开放图形，两个拐角切口中所有切口没有形成闭合回路。如图15-2所示，第一网格行、第三网格列对应的G子像素处形成一个拐角切口，该拐角切口的一个端部是第一网格行、第一网格列对应的G子像素。第三网格行、第四网格列对应的B子像素处形成另一个拐角切口，该拐角切口的一个端部是第三网格行、第六网格列对应的B子像素。由于两个拐角切口的端部没有重叠，因而两个拐角切口所形成的图形是开放图形。
本公开示例性实施例通过设置切口之间的相对位置关系，可以使得切口在金属网格上最大限度地均匀设置，可以避免在一个方向上或一个区域内多个切口因干涉产生亮度差异，可以降低切口的可见性，能够改善触控区的水印缺陷。
在示例性实施方式中，在触控区、边界区和连接桥区设置切口时，按照切口的方向，切口可以至少包括第一方向切口和第二方向切口。由于网格图案是由金属线构成的多边形，因此网格图案至少包括相互不平行的第一边和第二边，第一方向切口是截断第一边的切口，第二方向切口是截断第二边的切口。图16-1到图16-2为本公开示例性实施例方向切口的示意图。如图16-1所示，矩形的网格图案中，截断竖直方向金属线(第一边)的切口为第一方向切口(水平切口)，截断水平金属线(第二边)的切口为第二方向切口(竖直切口)。如图16-2所示，六边形的网格图案中，截断右上方向金属线(第一边)的切口为第一方向切口(左上切口)，截断左上方向金属线(第二边)的切口为第二方向切口(右上切口)。在示例性实施方式中，第一方向切口可以是水平切口、竖直切口和倾斜切口中的任意一种，第二方向切口可以是不同于第一方向切口的任意一种，倾斜切口包括左上切口和右上切口中的任意一种或多种。以下实施例中，以第一方向切口是水平切口、第二方向切口是竖直切口、第三方向切口是切斜切口为例进行说明。
在示例性实施方式中，切口密度是指一个重复单元内切口的数量与一个重复单元内网格图案的数量之比。图17为本公开示例性实施例切口密度的示意图。如图17所示，在一个重复单元内，如12*12个矩形网格图案，网格图 案的数量为144个，当重复单元内设置有58个切口时，则切口密度为58/144＝0.403。58个切口中，水平切口的数量是31，竖直切口的数量是27，则水平切口密度为31/144＝0.215，竖直切口密度为27/144＝0.188。在示例性实施方式中，一个重复单元内切口密度可以为10％到90％。
图18为本公开示例性实施例一种重复单元的示意图，重复单元包括12*12个网格图案，网格图案为矩形。重复单元的12*12个网格图案与显示结构层上12*12个子像素的形状相同，且位置相对应，12*12个子像素以GBRG正方形方式周期性排布。如图18所示，重复单元的切口包括第一水平切口901、第二水平切口902、第一竖直切口903和第二竖直切口904，第一水平切口901设置在水平方向排列的R子像素与G子像素之间，第二水平切口902设置在水平方向排列的B子像素与G子像素之间，第一竖直切口903设置在竖直方向排列的R子像素与G子像素之间，第二竖直切口904设置在竖直方向排列的B子像素与G子像素之间。
在示例性实施方式中，在一重复单元内，第一水平切口密度与第二水平切口密度的比值可以为0.7到1.3，第一竖直切口密度与第二竖直切口密度的比值可以为0.7到1.3。在一些可能的实现方式中，第一水平切口密度可以等于第二水平切口密度，第一竖直切口密度可以等于第二竖直切口密度。第一水平切口密度是重复单元中第一水平切口901的数量与重复单元中网格图案的数量之比，第二水平切口密度是重复单元中第二水平切口902的数量与重复单元中网格图案的数量之比，第一竖直切口密度是重复单元中第一竖直切口903的数量与重复单元中网格图案的数量之比，第二竖直切口密度是重复单元中第二竖直切口904的数量与重复单元中网格图案的数量之比。
例如，对于图18所示的12*12个网格图案的重复单元内，第一、第三、第五、第七、第九、第十一网格行中，第二水平切口902的数量分别是2、4、2、2、3、3，重复单元内第二水平切口902的数量为16。第二、第四、第六、第八、第十、第十二网格行中，第一水平切口901的数量分别是3、2、4、3、2、3，重复单元内第一水平切口901的数量为17，第一水平切口密度与第二水平切口密度的比值为1.06。又如，对于图18所示的12*12个网格图案的重复单元内，第一、第三、第五、第七、第九、第十一网格列中，第一竖直切 口903的数量分别是3、2、2、2、3、2，重复单元内第一竖直切口903的数量为14。第二、第四、第六、第八、第十、第十二网格列中，第二竖直切口904的数量分别是2、3、2、3、3、3，重复单元内第二竖直切口904的数量为16，第一竖直切口密度与第二竖直切口密度的比值为1.14。
由于第一水平切口设置在R子像素与G子像素之间，可以理解为一个第一水平切口对应一个R子像素和一个G子像素，因而当第一水平切口的数量为16时，16个第一水平切口将对应R子像素和G子像素。由于第二水平切口设置在B子像素与G子像素之间，可以理解为一个第二水平切口对应一个B子像素和一个G子像素，因而当第二水平切口的数量为17时，17个第二水平切口将对应B子像素和G子像素。这样，所有的水平切口中，对应R子像素的数量为16个，对应B子像素的数量为17个，对应G子像素的数量为33个，对应R子像素和对应B子像素的数量相近，对应G子像素的数量与对应R子像素和B子像素的数量相同。
由于第一水平切口设置在R子像素与G子像素之间，可以理解为一个R子像素有邻近的第一水平切口，一个G子像素有邻近的第一水平切口，因而当第一水平切口的数量为16时，16个R子像素有邻近的第一水平切口，16个G子像素有邻近的第一水平切口。由于第二水平切口设置在B子像素与G子像素之间，可以理解为一个B子像素有邻近的第二水平切口，一个G子像素有邻近的第二水平切口，因而当第二水平切口的数量为17时，17个B子像素有邻近的第二水平切口，17个G子像素有邻近的第二水平切口。这样，所有的子像素中，邻近有水平切口的R子像素的数量为16个，邻近有水平切口的B子像素的数量为17个，邻近有水平切口的G子像素的数量为33个，邻近有水平切口的R子像素和邻近有水平切口的B子像素的数量相近，邻近有水平切口的G子像素的数量与邻近有水平切口的R子像素和B子像素的数量相同。
重复单元内的切口可以划分为第一切口和第二切口，第一切口设置在R子像素与G子像素之间，即第一切口包括第一水平切口和第一竖直切口，第二切口设置在B子像素与G子像素之间，即第二切口包括第二水平切口和第二竖直切口。在示例性实施方式中，在重复单元内，第一切口密度与第二切 口密度的比值可以为0.7到1.3。
在示例性实施方式中，当子像素以其它方式周期性排布时，重复单元内的切口可以划分为第一切口、第二切口和第三切口，第一切口设置在R子像素与G子像素之间，第二切口设置在B子像素与G子像素之间，第三切口设置在R子像素与B子像素之间。在一重复单元内，第一切口密度与第二切口密度的比值可以为0.7到1.3，第二切口密度与第三切口密度的比值可以为0.7到1.3，第一切口密度与第三切口密度的比值可以为0.7到1.3。在一些可能的实现方式中，第一切口、第二切口和第三切口可以均包括水平(第一方向)切口、竖直(第二方向)切口和倾斜(第三方向)切口中的任意一种或多种，倾斜切口可以包括左上切口和右上切口中的任意一种或多种，本公开在此不做限定。
在一些可能的实现方式中，第一切口密度与第二切口密度的比值可以为0.7到1.3包括如下的任意一种或多种：第一水平切口密度与第二水平切口密度的比值可以为0.7到1.3，第一竖直切口密度与第二竖直切口密度的比值可以为0.7到1.3，第一倾斜切口密度与第二倾斜切口密度的比值可以为0.7到1.3。
在一些可能的实现方式中，第二切口密度与第三切口密度的比值可以为0.7到1.3包括如下的任意一种或多种：第二水平切口密度与第三水平切口密度的比值可以为0.7到1.3，所述第二竖直切口密度与第三竖直切口密度的比值可以为0.7到1.3，所述第二倾斜切口密度与第三倾斜切口密度的比值可以为0.7到1.3。
在一些可能的实现方式中，第一切口密度与第三切口密度的比值可以为0.7到1.3包括如下的任意一种或多种：第一水平切口密度与第三水平切口密度的比值可以为0.7到1.3，第一竖直切口密度与第三竖直切口密度的比值可以为0.7到1.3，第一倾斜切口密度与第三倾斜切口密度的比值可以为0.7到1.3。
图19为本公开示例性实施例另一种重复单元的示意图，重复单元包括9*6个网格图案，网格图案为六边形。如图19所示，在该重复单元中，第一水平切口的数量为4，第二水平切口的数量为4，第三水平切口的数量为4， 则第一水平切口密度与第二水平切口密度的比值为1，第二水平切口密度与第三水平切口密度的比值为1，第一水平切口密度与第三水平切口密度的比值为1。如图19所示，在该重复单元中，第一左上切口的数量为4，第二左上切口的数量为4，第三左上切口的数量为4，则第一左上切口密度与第二左上切口密度的比值为1，第二左上切口密度与第三左上切口密度的比值为1，第一左上切口密度与第三左上切口密度的比值为1。如图19所示，在该重复单元中，第一右上切口的数量为4，第二右上切口的数量为4，第三右上切口的数量为4，则第一右上切口密度与第二右上切口密度的比值为1，第二右上切口密度与第三右上切口密度的比值为1，第一右上切口密度与第三右上切口密度的比值为1。

图26-1到图26-3为一种连接桥区金属网格的结构示意图，为图3中B 区域的放大区，网格图案为菱形状。在垂直于触控结构层的方向上，触控结构层包括沿着远离显示结构层方向依次设置的桥接层、绝缘层和触控层，绝缘层设置在触控层和桥接层之间，实现两者的绝缘。在示例性实施方式中，桥接层包括下层金属网格，触控层包括上层金属网格。连接桥区金属网格包括位于桥接层的下层金属网格和位于触控层的上层金属网格，下层金属网格作为连接桥，配置为使位于触控层的第二触控电极20相互连接，上层金属网格配置为使位于同层的第一触控电极10相互连接。
图26-1为一种下层金属网格的结构示意图，下层金属网格设置在桥接层，作为在第二触控电极20之间建立连接的连接桥，第二触控电极20沿竖直方向间隔设置。如图26-1所示，下层金属网格包括相对于竖直线对称设置的两个连接网格301，每个连接网格301包括多个连接桥302，每个连接桥302包括焊盘部303和第二连接线304。焊盘部303设置在连接桥302的两端，配置为通过绝缘层上开设的过孔与位于触控层的第二触控电极20连接，第二连接线304设置两端的焊盘部30之间，配置为连接两端的焊盘部303。第二连接线304包括与连接桥302第一侧的焊盘部303连接的一条第二连接线和与连接桥302第二侧的焊盘部303连接的另一条第二连接线，一条第二从第一侧的焊盘部303向第二侧的焊盘部303延伸，另一条第二连接线从第二侧的焊盘部303向第一侧的焊盘部303延伸，两条第二连接线在交叉处相互连接。在示例性实施方式中，每个连接网格301包括2个到5个依次设置的连接桥302，形状相同的连接桥302从小到大依次套设。在示例性实施方式中，每个连接桥可以包括多个网格结构，多个网格结构相互连接。在示例性实施方式中，位于连接桥302端部的焊盘部303包括2个到4个第一焊盘，多个第一焊盘形成线形状、三角形状或正方形状排布。在示例性实施方式中，折线状的第二连接线304分别与两端的焊盘部303中的第一焊盘连接。
图26-2为一种上层金属网格的结构示意图，上层金属网格设置在触控层。如图26-2所示，上层金属网格包括第一触控电极10、第二触控电极20、第一连接单元305和第二连接单元306，第一触控电极10沿水平方向间隔设置，作为第一连接部的第一连接单元305将邻近的两个第一触控电极10连接起来。第二触控电极20沿竖直方向间隔设置，第二连接单元306和下层金属 网格一起作为第二连接部，连接邻近的两个第二触控电极20。第一连接单元305包括多条交织线，如图26-2中粗线所示，多条交织线相互交叉并分别向着两个第一触控电极10方向延伸，使邻近的两个第一触控电极10和第一连接单元305形成相互连接的一体结构。实际的交织线的线宽与网格图案中金属线的线宽相同，图26-2中用粗线标识只是为了清楚地描述交织线。第二连接单元306包括多个第二焊盘，多个第二焊盘的位置与下层金属网格的多个第一焊盘的位置相对应，配置为通过绝缘层上开设的过孔与位于桥接层的下层金属网格连接。多个第二焊盘分别位于第一连接单元305的两侧，每侧的第二焊盘与该侧的第二触控电极20连接。
一种连接桥区金属网格的设计中，上层金属网格的多个第二焊盘的位置与下层金属网格的多个第一焊盘的位置一一对应，下层金属网格的多个第一焊盘之间设置有第二连接线304，而上层金属网格中与第二连接线304相对应位置的金属线被去除，形成无金属线区域307，如图26-2所示。
图26-3为一种连接桥区金属网格的结构示意图，实线表示上层金属网格的金属线，虚线表示下层金属网格的金属线。上层金属网格和下层金属网格形成连接桥区后，下层金属网格有金属线的位置，上层金属网格没有金属线，上层金属网格有金属线的位置，下层金属网格没有金属线，如图26-3所示。研究表明，由于连接桥区的上层金属网格不完整，且连接桥区既有上层金属网格的金属线的反射，又有下层金属网格的金属线的反射，因而使得连接桥区的网格图案与触控区和边界区的网格图案差别较大，导致连接桥区出现点状、线状或块状的水印缺陷。
图27-1到图27-2为本公开示例性实施例连接桥区金属网格的结构示意图，为图3中B区域的放大区，网格图案为菱形状。连接桥区金属网格包括位于桥接层的下层金属网格和位于触控层的上层金属网格，下层金属网格作为连接桥，配置为使位于触控层的第二触控电极20相互连接，上层金属网格配置为使位于同层的第一触控电极10相互连接。
图27-1为本公开示例性实施例上层金属网格的结构示意图，上层金属网格设置在触控层。在示例性实施方式中，本公开下层金属网格可以采用图26-1所示结构。如图27-1所示，上层金属网格包括第一触控电极10、第二 触控电极20、第一连接单元305、第二连接单元306和第一连接线308，第一触控电极10沿水平方向间隔设置，作为第一连接部的第一连接单元305将邻近的两个第一触控电极10连接起来。第二触控电极20沿竖直方向间隔设置，作为第二连接部的第二连接单元306和下层金属网格一起连接邻近的两个第二触控电极20，第二连接单元306和第一连接线308间隔设置且相互绝缘。第一连接单元305的结构与图26-1所示的第一连接单元305的结构相同，使邻近的两个第一触控电极10和第一连接单元305形成相互连接的一体结构。第二连接单元306包括多个第二焊盘，多个第二焊盘的位置与下层金属网格的多个第一焊盘的位置相对应，即第二连接单元306的位置与下层金属网格的焊盘部的位置相对应，第二连接单元306配置为通过绝缘层上开设的过孔与位于桥接层的多个第一焊盘连接。多条第一连接线308的位置与下层金属网格的多条第二连接线304的位置相对应，第一连接线308配置为遮挡下层金属网格的第二连接线，第一连接线308上设置有多个切口，多个切口将第一连接线308截断，保证了上层金属网格的第二焊盘分别与第一触控电极10和第一连接单元305隔离。图27-1中粗线示意了第一连接线，实际的第一连接线的线宽与网格图案中金属线的线宽相同，图27-1中用粗线标识只是为了清楚地描述第一连接线。
图27-2为本公开示例性实施例连接桥区金属网格的结构示意图。如图27-2所示，上层金属网格和下层金属网格形成连接桥区后，下层金属网格有金属线的位置，上层金属网格设置有第一连接线，上层金属网格的第一连接线在基底上的正投影与下层金属网格的第二连接线在基底上的正投影基本重叠。本公开示例性实施例中，“A在基底上的正投影与B在基底上的正投影基本重叠”，是指A的正投影与B的正投影的重叠范围大于90％。在示例性实施方式中，第一连接线上设置有多个切口，上层金属网格的第一连接线在基底上的正投影与下层金属网格的第二连接线在基底上的正投影的重叠范围大于95％。这样，保证了连接桥区的上层金属网格的完整，连接桥区下层金属网格的金属线的反射被上层金属网格设置的第一连接线遮挡，连接桥区中金属线的反射主要来自于上层金属网格的金属线，因而使得连接桥区的网格图案与触控区和边界区的网格图案差别很小，有效避免了连接桥区出现点状、线状或块状的水印缺陷。
