技术领域

背景技术
随着有源矩阵有机发光二极管(Active-matrix organic light-emitting diode，AMLOED)显示行业的飞速发展，显示装置也朝着窄边框和轻薄化发展。目前，采用柔性多层一体化集成触控技术(Flexible Multi Layer On Cell，FMLOC)便可更好地实现这些高的需求。采用FMLOC技术的显示装置在设计时，触控结构层直接制作在叠设的发光结构层和封装层上面，减少了光学透明胶(Optically Clear Adhesive，OCA)的使用，且不需要通过驱动触控的柔性电路板(Touch FPC，TFPC)连接，可以很好地实现产品的轻薄化。
触控基板在设计过程中，存在较多工艺和技术问题，从而导致较多触控不良。其中，触控结构层在制备过程中，由于刻蚀后显示区域金属残留(Remain)而导致的触控结构层中金属走线之间短路(Short)不良占的比例最大。一些技术中，触控结构层中的驱动电极(Tx)和感应电极(Rx)采用金属网格(Metal Mesh)形式，检测设备在对触控结构层中的触控不良进行检测时，不能确定 不良出现的具体位置，导致不能及时对不良进行修复，影响产品良率提升。

在一些示例性实施方式中，图2-1到图2-5为几种金属网格的结构示意图。如图2-1到图2-5所示，金属网格包括多个网格图案，网格图案是由金属线构成的多边形，或者说，金属网格是由网格图案重复且连续设置拼接而成。在一些示例性实施方式中，金属线围成的网格图案的形状可以为菱形，如图2-1所示。或者，金属线围成的网格图案的形状可以为三角形，如图2-2所示。或者，金属线围成的网格图案的形状可以为矩形，如图2-3所示。或者，金属线围成的网格图案的形状可以为六边形，如图2-4所示。或者，金属线围成的网格图案的形状可以为多种形状的组合，如五边形和六边形的组合，如图2-5所示。或者，金属线围成的网格图案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。在一些可能的实现方式中，金属线围成的网格图案可以为规则的形状，或者为不规则的形状，网格图案的边可以为直线，或者可以为曲线，本公开实施例在此不做限定。在一些可能的实现方式中，金属网格的金属线的线宽≤5μm。
在一些示例性实施方式中，图3为一种金属网格形式的触控结构层的结构示意图，图3为图1中A区域的放大图，图3所示结构可看做是触控结构层的一个重复单元。如图3所示，触控结构层的触控层为金属网格状，网格图案为六边形。第一触控电极10和第二触控电极20同层设置在触控层上，为了使第一触控电极10和第二触控电极20相互绝缘，金属网格上设置有多个第一切口30，多个第一切口30断开网格图案的金属线，实现第一触控电极10的网格图案与第二触控电极20的网格图案的隔离。图3中采用黑色块表示第一切口30，第一切口30可以理解为切断金属线的假想线。位于第一触控电极10和第二触控电极20分界位置的多个第一切口30的假想连线可称为第一分界线500。在一些示例性实施方式中，触控结构层在平行于触控基板的方向上包括触控(Bulk)区100、边界(Boundary)区200和连接桥(Bridge)区300。位于边界区200的触控层的每一个网格图案中均设置有第一切口30，第一切口30截断网格图案的金属线，使每一个网格图案分为两部分，一部分属于第一触控电极10，另一部分属于第二触控电极20。触控区100包括第一触控电极10和第二触控电极。连接桥区300包括第一连接部和第二连接部，第一连接部用于实现相邻两个第一触控电极10之间的连接，第二连接部用于实现相邻两个第二触控电极20之间的连接，第一连接部和第二连接部中的一个位于触控层，另一个位于桥接层。在一些示例性实施方式中，触控区100的触控层上还设置有多个第二切口40，多个第二切口40断开网格图案的金属线，多个第二切口40在触控区100内可以形成一个或多个虚拟(Dummy)区70，虚拟(Dummy)区70可以与其所在触控区100内的第一触控电极10或第二触控电极20绝缘，虚拟区70的形状可以不受限制。虚拟(Dummy)区70可看做是多个第二切口40的假想连线所围成的区域，多个第二切口40的假想连线可称为第二分界线900。位于边界区200一侧的触控区100包括第一触控电极10和虚拟区70，位于边界区200另一侧的触控区100包括第二触控电极20和虚拟区70。在另一些示例性实施方式中，触控区100的触控层上设置的多个第二切口40可以不形成虚拟区70，在第一触控电极10和第二触控电极 20内部设置多个第二切口40，可使得切口在金属网格上尽可能均匀设置，避免只在边界区200设置切口，这样可改善边界区200的水印缺陷。
在一些示例性实施方式中，显示结构层包括规则排布的多个像素单元。每个像素单元可以包括红色(R)子像素、绿色(G)子像素和蓝色(B)子像素三个子像素。在另一些示例中，每个像素单元可以包括四个子像素，比如，每个像素单元包括红色子像素、绿色子像素、蓝色子像素和白色子像素，或者，每个像素单元包括红色子像素、两个绿色子像素和蓝色子像素。本公开实施例中对每个像素单元中的子像素的个数和排布方式不作限制。图4-1至图4-3示出了三种像素单元的结构示意图。四个子像素可以采用矩形状，以并列方式排列，从左到右分别为：R子像素、G子像素、B子像素和G子像素，如图4-1所示。或者，四个子像素可以分别采用五边形和六边形状，以并列方式排列，两个五边形的G子像素位于像素单元的中部，六边形的R子像素和六边形的B子像素分别位于G子像素的两侧，如图4-2所示。当像素单元包括三个子像素时，三个矩形状的子像素可以以水平方向并列方式排列，或者可以以竖直方向并列方式排列，如图4-3所示。在一些可能的实现方式中，子像素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、六边形和其它多边形中的任意一种或多种，排列方式可以是X形、十字形或品字形等，本公开实施例在此不做限定。

在一些示例性实施方式中，基底61为柔性基底，基底61可以包括叠设 的第一柔性材料层、第一无机材料层、半导体层、第二柔性材料层和第二无机材料层，第一柔性材料层和第二柔性材料层的材料可以采用聚酰亚胺(PI)、聚对苯二甲酸乙二酯(PET)或经表面处理的聚合物软膜等材料，第一无机材料层和第二无机材料层的材料可以采用氮化硅(SiNx)或氧化硅(SiOx)等，用于提高基底的抗水氧能力，半导体层的材料可以采用非晶硅(a-si)。
在一些示例性实施方式中，驱动电路层62可以包括构成像素驱动电路的晶体管和存储电容，图5中以每个子像素包括一个晶体管和一个存储电容为例进行示意。在一些可能的实现方式中，每个子像素的驱动电路层62可以包括：设置在基底上的第一绝缘层，设置在第一绝缘层上的有源层，覆盖有源层的第二绝缘层，设置在第二绝缘层上的栅电极和第一电容电极，覆盖栅电极和第一电容电极的第三绝缘层，设置在第三绝缘层上的第二电容电极，覆盖第二电容电极的第四绝缘层，第四绝缘层上开设有过孔，过孔暴露出有源层，设置在第四绝缘层上的源电极和漏电极，源电极和漏电极分别通过过孔与有源层连接，覆盖前述结构的平坦层。有源层、栅电极、源电极和漏电极组成晶体管，第一电容电极和第二电容电极组成存储电容。在一些可能的实现方式中，第一绝缘层、第二绝缘层、第三绝缘层和第四绝缘层可以采用硅氧化物(SiOx)、硅氮化物(SiNx)和氮氧化硅(SiON)中的任意一种或多种，可以是单层、多层或复合层。第一绝缘层可称之为缓冲(Buffer)层，用于提高基底的抗水氧能力，第二绝缘层和第三绝缘层可称之为栅绝缘(GI)层，第四绝缘层可称之为层间绝缘(ILD)层。第一金属薄膜、第二金属薄膜和第三金属薄膜可以采用金属材料，如银(Ag)、铜(Cu)、铝(Al)、钛(Ti)和钼(Mo)中的任意一种或多种，或上述金属的合金材料，如铝钕合金(AlNd)或钼铌合金(MoNb)，可以是单层结构，或者多层复合结构，如Ti/Al/Ti等。有源层薄膜可以采用非晶态氧化铟镓锌材料(a-IGZO)、氮氧化锌(ZnON)、氧化铟锌锡(IZTO)、非晶硅(a-Si)、多晶硅(p-Si)、六噻吩或聚噻吩等材料，即本公开实施例适用于基于氧化物(Oxide)技术、硅技术或有机物技术制造的晶体管。
在一些示例性实施方式中，发光结构层63可以包括阳极、像素定义层、有机发光层和阴极，阳极设置在平坦层上，通过平坦层上开设的过孔与漏电极连接，像素定义层设置在阳极和平坦层上，其上设置有像素开口，像素开口暴露出阳极，有机发光层设置在像素开口内，阴极设置在有机发光层上，有机发光层在阳极和阴极施加电压的作用下出射相应颜色的光线。在一些示例性实施方式中，封装层64可以包括叠设的第一封装层、第二封装层和第三封装层，第一封装层和第三封装层可采用无机材料，第二封装层可采用有机材料，封装层64可以防止外界水汽进入发光结构层63。
在一些示例性实施方式中，显示结构层包括发光区域和非发光区域。如图5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。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。
在一些示例性实施方式中，如图6所示，显示结构层包括规则排布的多个像素单元50，当像素单元50采用图4-2所示的结构时，触控结构层中触控层的金属网格的网格图案801为六边形，网格图案801的形状与像素单元50中的B子像素和R子像素的形状相适配。一个像素单元50中的B子像素和R子像素分别位于两个网格图案801所围成的区域内，两个G子像素位于同一个网格图案801所围成的区域内。网格图案801的金属线位于相邻子像素之间的子像素边界内。
本公开实施例中，网格图案的形状为多边形的情况下，多边形的每条边可看做为网格图案的每条金属线，多边形的边数即为网格图案的金属线的条数。比如，网格图案为六边形时，网格图案具有六条金属线。网格图案中，设置有第一切口的金属线称为第一金属线，设置有第二切口的金属线称为第 二金属线。以第一切口和第一金属线为例说明，第一切口可以设置在第一金属线的中间位置(可以是居中位置或者非居中位置)，则第一金属线从中间断开而形成两个第一断线。或者，第一切口可以设置在第一金属线的一端位置，则可看作第一金属线的该端部被第一切口切掉，第一金属线剩下的部分形成一个第一断线。同理，第二切口、第二金属线和第二断线可做相同理解。
一些触控基板中，如图7所示，位于第一触控电极10和第二触控电极20分界位置的网格图案设置有第一切口30，第一触控电极10内部设置有第二切口40。由第一切口30形成的第一断线31的形态与由第二切口40形成的第二断线41的形态相同。这样，当第一切口30或第二切口40处存在金属残留(Remain)而导致金属线之间短路(Short)不良时，由于第一切口30和第二切口40不能被区分，因此，检测设备(例如自动光学检测(Automated Optical Inspection)设备，简称AOI设备)在检测出金属残留类不良时，不能确定该不良所在的具体位置是属于边界区还是属于触控区，从而不能及时对不良进行维修，影响良率提升。
在一些示例性实施例中，所述第一断线单元的形态包括所述第一断线31的端面形状，所述第二断线单元的形态包括所述第二断线41的端面形状，所述第一断线31的端面形状不同于所述第二断线41的端面形状。示例性地，如图8所示，图8示出了并排的三个网格图案，网格图案为六边形。网格图案中的细线代表第一触控电极10，粗线代表第二触控电极20。本文中，网格图案中的细线和粗线只是为了区分第一触控电极10和第二触控电极20，不代表真实线宽，真实线宽可以是相同的。中间的网格图案和右侧的网格图案所共用的金属线的中间位置设有第一切口30，该金属线(即第一金属线)包括两个第一断线31。左侧的网格图案和中间的网格图案所共用的金属线的中间位置设有第二切口40，该金属线(即第二金属线)包括两个第二断线41。第二切口40设置在第一触控电极10的网格图案上。本示例的图8中，只是示出了一个第一切口30和一个第二切口40，三个网格图案中第一触控电极10和第二触控电极20分界位置的其他第一切口30并未示出。示例性地，第二 断线41的端面411为平面，第一断线31的端面311可以为曲面、斜面、折面中的任一种或多种。曲面可以是弧面、波浪面等。折面包括至少两个相交的面，比如，折面包括相交的平面和斜面，或者，折面包括相交的多个斜面。在其他示例中，第二断线41的端面411可以为曲面、斜面、折面中的任一种，第一断线31的端面311可以为平面、曲面、斜面、折面中不同于第二断线41的端面形状的任一种或多种。图8所示的示例中，两个第二断线41的端面411均为平面，两个第一断线31的端面311均为弧面，或者，其中一个第一断线31的端面311设置为弧面，另一个第一断线31的端面311设置为平面或其他任意形状。
在一些示例性实施例中，所述第一切口使所在的金属线从中间断开而形成两个所述第一断线，所述第二切口使所在的金属线从中间断开而形成两个所述第二断线；所述第一断线单元的形态包括两个所述第一断线的长度，所述第二断线单元的形态包括两个所述第二断线的长度；两个所述第一断线的长度相同，两个所述第二断线的长度不同；或者，两个所述第一断线的长度不同，两个所述第二断线的长度相同。以两个所述第一断线的长度不同，两个所述第二断线的长度相同为例说明，如图9所示，图9示出了并排的三个网格图案，网格图案为六边形。网格图案中的细线代表第一触控电极10，粗线代表第二触控电极20。中间的网格图案和右侧的网格图案所共用的金属线的非居中位置设有第一切口30，第一切口30使得该金属线从中间断开而形成两个不同长度的第一断线31。左侧的网格图案和中间的网格图案所共用的金属线的居中位置设有第二切口40，第二切口40使得该金属线从中间断开而形成两个相同长度的第二断线41。第二切口40设置在第一触控电极10的网格图案上。
在一些示例性实施例中，所述第一断线单元的形态包括所述第一断线的数目，所述第二断线单元的形态包括所述第二断线的数目，所述第一断线的数目与所述第二断线的数目不同；所述第一切口使所在的金属线从中间断开而形成两个所述第一断线，或者，所述第一切口使所在的金属线的一端切掉 而形成一个所述第一断线。以所述第一切口使所在的金属线的一端切掉而形成一个所述第一断线为例说明，如图10所示，图10示出了五个网格图案，五个网格图案呈两行排布，网格图案为六边形。第一行左侧的网格图案的一个竖直金属线上设有第一切口30，第一切口30使该竖直金属线的一端切掉而形成一个第一断线31。第一行左侧的网格图案与第二行中间的网格图案所共用的金属线上设有第一切口30，第一切口30使该金属线的一端切掉而形成一个第一断线31。第二行中间的网格图案与第二行右侧的网格图案所共用的金属线设有第一切口30，第一切口30使该金属线的一端切掉而形成一个第一断线31。第二行右侧的网格图案的另一个金属线设有第一切口30，第一切口30使该金属线的一端切掉而形成一个第一断线31。图10示出的五个网格图案中共四个第一切口30和四个第一断线31，设置有第一切口30的金属线(即第一金属线)均形成一个第一断线31。第二触控电极20的网格图案中设置有第二切口40，第二切口40使所在的金属线从中间断开而形成两个第二断线41。
在一些示例性实施例中，在所述第一切口使所在的金属线的一端切掉而形成一个所述第一断线的情况下，将所述多个第一切口的假想连线称为第一分界线，沿着所述第一分界线的延伸方向，相邻的两个所述第一断线中的一个与所述第一触控电极连接，另一个与所述第二触控电极连接。如图10所示，设置有第一切口30的网格图案中，网格图案的至少两个金属线均设置有第一切口30，设置有第一切口30的金属线(即第一金属线)均形成一个第一断线31。图10示出的五个网格图案中共四个第一切口30和四个第一断线31，串连这四个第一切口30的假想连线为第一触控电极10和第二触控电极20的第一分界线500。第一分界线500一侧的网格图案为第一触控电极10，第一触控电极10的网格图案用细线表示，第一分界线500另一侧的网格图案为第二触控电极20，第二触控电极20用粗线表示。沿着第一分界线500的延伸方向，相邻的两个第一断线31中的一个第一断线31与第一触控电极10连接，另一个第一断线31与第二触控电极20连接，也可理解为，沿着第一分界线500的延伸方向，第一触控电极10和第二触控电极20交替设置有第一断线31。 沿着第一分界线500的延伸方向，第一触控电极10和第二触控电极20交替设置有第一断线31，这样，一方面有利于区分第一切口30和第二切口40，另一方面可减少第一触控电极10和第二触控电极20的分界位置发生金属走线短路的风险。
在一些示例性实施例中，所述第一切口使所在的金属线从中间断开而形成两个所述第一断线，所述第二切口使所在的金属线从中间断开而形成两个所述第二断线；所述第一断线单元的形态包括两个所述第一断线之间的距离，所述第二断线单元的形态包括两个所述第二断线之间的距离，两个所述第一断线之间的距离不同于两个所述第二断线之间的距离。示例性地，如图11所示，图11示出了并排的三个网格图案，网格图案为六边形。网格图案中的细线代表第一触控电极10，粗线代表第二触控电极20。中间的网格图案和右侧的网格图案所共用的金属线的中间位置设有第一切口30，第一切口30使该金属线从中间断开而形成两个第一断线31。左侧的网格图案和中间的网格图案所共用的金属线的中间位置设有第二切口40，第二切口40使该金属线从中间断开而形成两个第二断线41。第二切口40设置在第一触控电极10的网格图案上。图11所示实施例中，两个第一断线31之间的距离大于两个第二断线41之间的距离，也可理解为，第一切口30的宽度大于第二切口40的宽度。两个第一断线31之间的距离增大，一方面有利于区分第一切口30和第二切口40，另一方面可减少第一触控电极10和第二触控电极20的分界位置发生金属走线短路的风险。
在一些示例性实施例中，为了使所述第一断线单元的形态不同于所述第二断线单元的形态，可以采用如下方案：所述第一断线上设置有标记部，所述第二断线上未设置所述标记部；或者，与所述第一断线相邻的金属线上设置有标记部，与所述第二断线相邻的金属线上未设置所述标记部。示例性地，所述标记部可以包括凸出于其所在的金属线设置的凸条或凸块。所述凸块可以为多边形、圆形、椭圆形中的任一种或多种。多边形可以为三角形、矩形、菱形等。
在一些示例性实施例中，所述第一断线的靠近所述第一切口的端部设置有所述标记部。示例性地，如图12所示，图12示出了并排的三个网格图案，网格图案为六边形。网格图案中的细线代表第一触控电极10，粗线代表第二触控电极20。中间的网格图案和右侧的网格图案所共用的金属线的中间位置设有第一切口30，第一切口30使该金属线从中间断开而形成两个第一断线31，第一断线31的靠近第一切口30的端部设置有标记部600，该标记部600为凸块，凸块的形状可以不受限制，比如可以为矩形、菱形、圆形、椭圆形等规则图形或不规则图形，凸块在垂直于第一断线31的方向上凸出于第一断线31的其余部分。左侧的网格图案和中间的网格图案所共用的金属线的中间位置设有第二切口40，第二切口40使该金属线从中间断开而形成两个第二断线41，第二断线41上未设置所述标记部600，第二切口40设置在第一触控电极10的网格图案上。本实施例中，两个第一断线31中至少一个的靠近第一切口30的端部设置有标记部600，两个第一断线31的靠近第一切口30的端部可以均设置有标记部600。
在一些示例性实施例中，所述第一断线与其他金属线相交的位置设置有所述标记部。本实施例中，当第一切口使所在的金属线从中间断开而形成两个第一断线时，两个第一断线与其他金属线相交的位置有两个，该两个相交位置中可以有一个相交位置设置所述标记部，或者两个相交位置均设置有所述标记部。所述标记部可以为凸出于其所在相交位置的凸条或凸块。本实施例的一个示例中，如上图13所示，图13示出了五个网格图案，五个网格图案呈两行排布，网格图案为六边形。网格图案中的细线代表第一触控电极10，粗线代表第二触控电极20。第一行左侧的网格图案的左侧竖直金属线上设有第一切口30，第一切口30使该竖直金属线从中间断开而形成上下两个第一断线31，下部的第一断线31与第一行左侧的网格图案的左下部的倾斜金属线相交的位置设置有标记部600。第一行左侧的网格图案与第二行中间的网格图案所共用的金属线上设有第一切口30，第一切口30使该金属线从中间断开而形成两个第一断线31，两个第一断线31分别与第一行左侧的网格图案的左下部 的倾斜金属线和第一行左侧的网格图案的右侧竖直金属线相交的位置均设置有标记部600。第二行中间的网格图案与第二行右侧的网格图案所共用的金属线设有第一切口30，第一切口30使该金属线从中间断开而形成上下两个第一断线31，两个第一断线31分别与其他金属线相交的位置均设置有标记部600。第二行右侧的网格图案的左下部的倾斜金属线设有第一切口30，第一切口30使该金属线从中间断开而形成两个第一断线31，其中一个第一断线31与第二行右侧的网格图案的左侧竖直金属线相交的位置设置有标记部600。第二行右侧的网格图案的右上部的金属线上设置有第二切口40，第二切口40使该金属线从中间断开而形成两个第二断线41，两个第二断线41上未设置标记部600。第二切口40设置在第二触控电极20内部。本示例中，标记部600为凸块，凸块的形状为矩形，在其他示例中，凸块的形状可以为圆形、椭圆形、菱形或三角形等规则图形或不规则图形。本示例中，第一切口30使所在的金属线从中间断开而形成两个第一断线31，第二切口40使所在的金属线从中间断开而形成两个第二断线41，在其他示例中，第一切口30可以使所在的金属线的一端切掉而形成一个第一断线31，第二切口40可以使所在的金属线的一端切掉而形成一个第二断线41。
在一些示例性实施例中，与所述第一断线相邻的金属线上设置有标记部，与所述第二断线相邻的金属线上未设置所述标记部。本实施例的一个示例中，与所述第一断线相邻的金属线的中间位置(居中或非居中位置)设置有所述标记部。所述标记部可以为凸出于其所在金属线的凸条或凸块。示例性地，如图14所示，图14示出了五个网格图案，五个网格图案呈两行排布，网格图案为六边形。网格图案中的细线代表第一触控电极10，粗线代表第二触控电极20。第一行左侧的网格图案的一个竖直金属线上设有第一切口30，第一切口30使该竖直金属线从中间断开而形成上下两个第一断线31。第一行左侧的网格图案与第二行中间的网格图案所共用的金属线上设有第一切口30，第一切口30使该金属线从中间断开而形成两个第一断线31。第二行中间的网格图案与第二行右侧的网格图案所共用的金属线设有第一切口30，第一切口30 使该金属线从中间断开而形成两个第一断线31。第二行右侧的网格图案的左下部的倾斜金属线设有第一切口30，第一切口30使该金属线从中间断开而形成两个第一断线31。第二行右侧的网格图案的右上部的金属线上设置有第二切口40，第二切口40使该金属线从中间断开而形成两个第二断线41，两个第二断线41与第一断线31不相邻(可理解为不直接相连)。第二切口40设置在第二触控电极20内部。第一行左侧的网格图案与第二行左侧的网格图案所共用的金属线上设置有标记部600，该设置有标记部600的金属线与连接在其两端的两个第一断线31均相邻。第二行中间的网格图案的右上部的倾斜金属线上设置有标记部600，该金属线与连接在其两端的两个第一断线31均相邻。第二行中间的网格图案中，位于右下部的倾斜金属线上设置有标记部600，该倾斜金属线与连接在其同一端的两个第一断线31均相邻。网格图案中，与第二断线41相邻的金属线上未设置标记部。本示例中，标记部600为凸出于其所在金属线的凸条，标记部600的数目设置为一个。在其他示例中，标记部600可以为凸出于其所在金属线的凸块，标记部600的数目可以为一个或多个。本示例中，第一切口30使所在的金属线从中间断开而形成两个第一断线31，第二切口40使所在的金属线从中间断开而形成两个第二断线41，在其他示例中，第一切口30可以使所在的金属线的一端切掉而形成一个第一断线31，第二切口40可以使所在的金属线的一端切掉而形成一个第二断线41。
上述图8-图14示出的实施例中，通过采用多种方案使得所述第一断线单元的形态不同于所述第二断线单元的形态，从而使得第一切口与第二切口能够被区分。这样，检测设备(例如AOI设备)在对触控结构层出现的不良进行检测时，由于第一切口和第二切口能够被区分，因此，检测设备可以确定不良所在的具体位置是属于第一触控电极和第二触控电极的分界位置还是属于分界位置以外的其他位置，进而可以及时对不良进行维修，提升产品良率。
基于同一发明构思，本公开实施例还提供了另一种触控基板，请参考图15至图23。具体地，图16为图15中虚线框区域S的触控电极层结构的放大示意图。图17至图23的结构示意图是对本公开具体实施例的示例说明。触 控基板包括衬底基板100和位于衬底基板100上的触控电极层，触控电极层具有由导线组成的网格状结构；
如图15至图23所示，触控电极层包括多条沿第一方向X延伸的第一触控电极1和多条沿第二方向Y延伸的第二触控电极2，第一方向X和第二方向Y相交；第一触控电极1包括沿第一方向X布置的多个第一触控子电极10，第二触控电极2包括沿第二方向Y布置的多个第二触控子电极20，第一触控子电极10包括多个第一触控电极网格11(图16中由灰色线条所围成的网格)，第二触控子电极20包括多个第二触控电极网格12(图16中由黑色线条所围成的网格)；触控电极层还包括位于相邻的第一触控子电极10与第二触控子电极20之间的多个分界网格13(图16中由灰色线条和黑色线条共同围成的网格)，每个分界网格13中包括至少两个第一网线21，每个第一网线21上设有第一断口210，多个分界网格13中的第一断口210使得相邻的第一触控子电极10和第二触控子电极20之间绝缘；第一触控电极网格11和/或第二触控电极网格12中设有第二网线22，第二网线22上设有第二断口220；
如图17至图23所示，第一网线21与第二网线22的图案形状不同；或者，分界网格13中的网线上设有凸出部3。
具体地，‘网线’即围成网格的线条，本公开中触控电极层为通过导线围成的网格状结构，则网线的材料即为导线；示例性的，导线可以为金属材料，即触控电极层可以为金属网格图形结构。
具体地，第一触控电极(第一触控子电极)和第二触控电极(第二触控子电极)可以分别被配置为发射电极和感应电极。图15中的虚线框区域包括一条第一触控电极1与一条第二触控电极2的交叉区域，该交叉区域沿第一方向X的两个第一触控子电极10(第一触控电极网格11)直接相连，该交叉区域沿第二方向Y的两个第二触控子电极20(第二触控电极网格12)通过桥结构200电连接。具体地，桥结构200也可以采用网格结构，例如，图16中所示的交叉区域内放大图即是触控电极层网格和桥结构网格图案交叠后的示意图。具体地，触控电极层网格中，第一触控电极网格11与第二触控电极网 格12之间具有分界网格13，分界网格13中的第一断口210将第一触控电极网格11和第二触控电极网格12之间断开，从而使得第一触控子电极10与第二触控子电极20之间绝缘。
具体地，本公开实施例提供的附图中，参照图16至图23所示，完全由灰色线条围成的网格为第一触控电极网格11，完全由黑色线条围成的网格为第二触控电极网格12，由灰色线条和黑色线条共同围成的网格为分界网格13。需要说明的是，本公开实施例提供附图中仅示意性的画出了触控电极层中的部分网格结构以及网格结构中的部分断口，因此具体实施时，触控电极层的实际图形并不限定以这些附图为标准。具体地，触控电极层中，分界网格中设有的所有第一断口被配置为能够将第一触控电极网格与第二触控电极网格之间的电连接断开；第一触控电极网格和第二触控电极网格中设有的第二断口，具体可以根据电流分配需求和/或避免连续图案导致摩尔纹等要求进行布置。
具体地，第一方向X和第二方向Y为正交，即第一触控电极1延伸方向与第二触控电极2延伸方向可以是相互正交。
本公开实施例提供的触控基板中，触控电极层包括第一触控子电极10(第一触控电极网格11)、第二触控子电极20(第二触控电极网格12)以及位于第一触控子电极10和第二触控子电极20之间的分界网格13，分界网格13中设有第一断口210以使得第一触控子电极10(第一触控电极网格11)和第二触控子电极20(第二触控电极网格12)之间断开并绝缘，第一触控电极网格11和/或第二触控电极网格12中设有第二断口220，由于设有第一断口210的第一网线21的图案形状与设有第二断口220的第二网线22的图案形状设置不同，或者在分界网格13中的网线上设置有凸出部3，进而很容易有效地将分界网格13与第一触控电极网格11和第二触控电极网格12区分开，并可以直接区别第一网线21与第二网线22以及第一断口210与第二断口220，进而，当触控电极层出现不良时，通过检测设备能够快速有效地检测不良出现的具体位置，并能及时修复，从而提高良率。
具体地，例如，由于金属残留(Remain)等问题，触控电极层很容易出现网线断口电连接而导致短路(Short)不良，此时，通过光学检测设备(AOI)很难判断出不良断口的具体位置。本公开中，由于设有断口的第一网线和第二网线的图案形状不同，因此，通过光学检测设备(AOI)即可以很容易找到不良断口所处位置，并确定不良位置是触控单元网格内部还是两个触控单元之间的分界网格处，进而能够有效提高检测和修复的效率。
另外，由于触控电极层中，设有第一断口210的第一网线21的图案形状与设有第二断口220的第二网线22的图案形状设置不同，或者在分界网格13中的网线上设置有凸出部3，使得分界网格的图案与触控电极网格(第一触控电极网格和第二触控电极网格)的图案形状不同，进而很容易区分分界网格与触控电极网格，因此，本公开实施例的方案，除了能够快速判断触控电极层短路不良的具体位置，还能够提高对其他不良的具体位置和类型的判断效率和对不良的修复效率，例如有利于提高某处的断路不良的检出效率，此处不再赘述。
具体地，本公开实施例提供触控基板可以是采用柔性多层一体化集成触控技术(FMLOC)制备而成的显示基板，即显示基板在设计时，在发光膜层和封装膜层上面直接制作触控电极的膜层，减少了光学胶(OCA)的使用，且不需要通过触控柔性线路板(TFPC)连接，可以很好的实现产品的轻薄化。
当然，本公开实施例提供的触控基板也可以是独立于显示基板的结构，被配置为通过光学胶(OCA)与显示基板贴合。
如图16所示，一些实施例中，触控电极层的网格状结构中的每一个网格(第一触控电极网格11，第二触控电极网格12以及分界网格13)为六边形。此时，触控电极层呈蜂窝状图案，结构规则，稳定性很好且便于构图，而且开口率很大，有利于提高显示面板的开口率。
具体地，图17至图23中示意出了部分第一触控电极网格11和分界网格13，下面以图17至图23作为参考，对于本公开的一些具体实施例进行举例说明。
如图17至图23所示，一些实施例中，分界网格13包括第一网线21，第一网线21包括第一断口210和第一断线211，第一断口210将第一网线21断开以形成第一断线211；第一触控电极网格11和/或第二触控电极网格中设有第二网线22，第二网线22具有第二断口220和第二断线221，第二断口220将第二网线22断开以形成第二断线221。
具体地，第一网线21和第二网线22均是围成网格的一段网线，例如，网格为六边形，则第一网线21和第二网线22即是围成六边形的一条边。
具体地，第一网线21是围成分界网格13的一段网线，第二网线22是围成第一触控电极网格11和/或第二触控电极网格的一段网线。第一网线21和第二网线22内均设有断口，从而使得第一网线21和第二网线22内形成有断线，断线之间的电连接被断开。
示例性的，第一触控电极网格11和第二触控电极网格中均设有第二网线22，即第一触控电极网格11和第二触控电极网格内均设有第二断口220。
如图17至图22所示，一些实施例中，第一断口210和第一断线211的图案形状与第二断口220和第二断线221的图案形状不同。
具体地，第一断口210和第一断线211的图案形状与第二断口220和第二断线221的图案形状不同，则很容易判断不良断口是位于触控电极单元内还是位于两个触控电极单元的分界处，进而很容易确定不良的具体位置和类型，例如，很容易确定是两个触控电极之间的第一网线21短接不良，还是某个触控电极内部的第二网线22短接不良。
一些具体的实施例中，如图17和图18所示，第一断线211靠近第一断口210的一端的横截面形状与第二断线221靠近第二断口220的一端的横截面形状不同。进而，通过观察断线端部的横截面形状，即可以判断相应的断口和断线的类型及所在的位置。
示例性的，第一断线211靠近第一断口210的一端的横截面为非矩形；第二断线221靠近第二断口220的一端的横截面为矩形。
具体地，例如，如图17所示，第一断线211靠近第一断口210的一端的 横截面可以为扇形，或者，如图18所示，第一断线211靠近第一断口210的一端的横截面可以为T型。
一些具体的实施例中，如图19所示，第一断线211的长度与第二断线221的长度不同。具体地，通过观察断线长度，即可以判断相应的断口和断线的类型及所在的位置。
示例性的，如图19所示，第一网线21包括一个第一断口210和分别位于第一断口210两端的两个第一断线211；两个第一断线211的长度不同。第二网线22包括一个第二断口220和分别位于第二断口220两端的两个第二断线221；两个第二断线221的长度相同。此时，两个第一断线211和两个第二断线221的长度均不同，两个第二断线221相对于第二断口220对称设置，两个第一断线211在第一断口210两侧长度参差不齐，进而很容易区分。
一些具体的实施例中，如图20所示，第一断口210的间距宽度与第二断口220的间距宽度不同。具体地，通过观察断口宽度大小，即可以判断相应的断口和断线的类型及所在的位置。
示例性的，第一断口210的间距宽度大于第二断口220的间距宽度。
一些具体的实施例中，如图21所示，第一网线21中的第一断线211与第二网线22中的第二断线221的数量不同。具体地，通过观察与断口相邻的断线的数量，即可以判断相应的断口和断线的类型及所在的位置。
示例性的，第一网线21包括一个第一断口210和位于第一断口210一端的一个第一断线211。第二网线22包括一个第二断口220和分别位于第二断口220两端的两个第二断线221。
一些具体的实施例中，如图22所示，第一网线21的端部尺寸和/或形状与第二网线22的端部尺寸和/或形状不同。具体地，通过观察网线的端部尺寸和/或形状，即可以判断该段网线的断口和断线的类型及所在的位置。
示例性的，第二网线22的两个端部的尺寸相同；第一网线21的至少一个端部的尺寸大于第二网线22的端部尺寸。例如，如图22所示，第一网线21的两个端部的尺寸均大于第二网线22的两个端部的尺寸。
示例性的，第二网线22的两个端部形状呈常规的圆形，第一网线21的两个端部的形状可以呈方形。
如图23所示，一些实施例中，分界网格中的网线上设有凸出部3，设有凸出部3的网线位于分界网格中两个第一网线21之间。示例性的，设有凸出部3的网线的两端分别与两个第一网线21相连。具体地，通过观察网线上是否具有凸出部，即可以确定与该段网线相邻的网线、断口和断线的类型及所在的位置。
示例性的，该凸出部3为一段线形结构，并相对于与其相连的网线垂直伸出。
示例性的，该凸出部3相对于与其相连的网线朝向分界网格的内侧凸出。
基于同一发明构思，本公开还提供了一种显示装置，该显示装置包括上述任一项的触控基板。
具体地，该显示装置可以为OLED显示装置，具体可以应用于平板电脑、手机等显示设备。
示例性的，该显示装置可以为FMLOC显示装置，集成度高，比较轻薄。
需要说明的是，本公开的一些实施例中，触控基板和显示装置还可以包括其他的结构，这可以根据实际需求而定，本公开的实施例对此不作限制。另外，关于本公开实施例提供的网格结构的形状，第一网线，第一断口，第一断线，第二网线，第二断口，第二断线等结构的尺寸和形状并不限于上述实施例，只要能够使得分界网格中第一网线的图案形状与触控电极网格中第二网线的图案形状不同即可，此处不再赘述。再者，本公开附图只是示意图，图中各部分结构的具体尺寸和比例并不代表各结构的实际尺寸比例。
显然，本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
