在本公开提供的一些实施例中，如图2和图3所示，前述显示面板100包 括触控结构10和发光基板20。
其中，参阅图2，前述发光基板20包括多个子像素P，发光基板20被配置为实现发光显示。
参阅图3，前述发光基板20包括衬底21，以及层叠设置于衬底21上的像素电路层22和发光器件层23。
衬底21可为单层结构，也可为多层结构。例如，该衬底21可包括依次层叠设置的柔性基层和缓冲层。又例如，衬底21可包括交替设置的多个柔性基层和缓冲层。其中，柔性基层的材料可包括聚酰亚胺，缓冲层的材料可包括氮化硅和/或氧化硅，以达到阻水氧和阻隔碱性离子的效果。
像素电路层22包括依次层叠设置在衬底21上的有源层201、第一栅绝缘层202、第一栅导电层203、第二栅绝缘层204、第二栅导电层205、层间介质层206、第一源漏导电层207、钝化层208、第一平坦化层209、第二源漏导电层210、第二平坦化层211。
可选地，源漏导电层可以只有一层(例如只有第一源漏导电层207或只有第二源漏导电层210)，相应地，平坦化层也可以只有一层(例如只有第一平坦化层209或只有第二平坦化层211)。
像素电路层22设置有多个薄膜晶体管TFT和多个电容结构Cst。每个子像素P对应包括至少一个薄膜晶体管TFT和至少一个电容结构Cst。图3中仅示例性示出了其中两个薄膜晶体管TFT和对应的两个电容结构Cst。
其中，薄膜晶体管TFT包括栅极Ta、源极Tb、漏极Tc以及有源层图案Td。源极Tb、漏极Tc和有源层图案Td电接触。
该有源层图案Td被配置为在栅极Ta的控制下形成沟道，使得与有源层图案Td连接的源极Tb和漏极Tc之间导通，从而打开薄膜晶体管TFT。示例性地，薄膜晶体管TFT还包括位于栅极Ta所在膜层和有源层图案Td所在膜层之间的第一栅绝缘层202的部分。
需要说明的是，各薄膜晶体管TFT的控制极为晶体管的栅极Ta，第一极为薄膜晶体管TFT的源极Tb和漏极Tc中一者，第二极为薄膜晶体管TFT的源极Tb和漏极Tc中另一者。由于薄膜晶体管TFT的源极Tb和漏极Tc在结构上可以是对称的，所以其源极Tb和漏极Tc在结构上可以是没有区别的。
电容结构Cst包括第一极板Cst1和第二极板Cst2，其中，第一极板Cst1位于第一栅导电层203，第二极板Cst2位于第二栅导电层205。
发光器件层23包括依次层叠设置在像素电路层22远离衬底21一侧的阳 极层301、像素界定层302、发光功能层303以及阴极层304。

其中，位于阳极层301的阳极L4被配置为传输高电平电压(例如电源电压信号VDD)，位于阴极层304的阴极L5被配置为传输低电平电压(例如阴极电压信号VSS)。在阳极L4和阴极L5形成的电场的作用下，发光图案L3可以实现发光。
示例性地，发光功能层303除包括发光图案L3外，还可以包括电子传输层(Election Transporting Layer，简称ETL)、电子注入层(Election Injection Layer，简称EIL)、空穴传输层(Hole Transporting Layer，简称HTL)以及空穴注入层(Hole Injection Layer，简称HIL)中的一层或多层。
示例性地，阳极L4可与薄膜晶体管TFT的源极Tb或漏极Tc电连接，从而使得发光器件L在薄膜晶体管TFT的控制下实现发光。
示例性地，如图3所示，像素界定层302开设有多个开口K，发光图案L3至少部分位于开口K内，发光图案L3发出的光通过开口K发射至外界。
示例性地，如图3所示，像素界定层302和阴极层304之间还可设置有支撑层305，该支撑层305可起到支撑保护膜层的作用，以避免保护膜层与阳极层301或其他走线接触而导致阳极层301或其他走线断裂。
示例性地，如图3所示，发光基板20还包括设于发光器件L远离衬底21一侧的封装层24。封装层24可以包括远离衬底21依次层叠设置的第一封装子层、第二封装子层和第三封装子层。示例性地，第一封装子层和第三封装子层的材料包括无机材料，第二封装子层的材料包括有机材料。第一封装子层和第三封装子层具有阻隔水汽和氧气的作用，而第二封装子层具有一定的柔性和吸收水汽的作用等。
前述发光基板20具有出光侧和背光侧，出光侧是指发光基板20发出光线的一侧，背光侧是指发光基板20的背离出光侧的一侧。
参阅图3，前述触控结构10设置在发光基板20的出光侧。
该触控结构10可以被配置为，感应用户的触摸并获取触控信息，例如，感应用户手指或触控笔的触摸，并获取触摸坐标信息，实现显示面板100的触控功能。
在一些实施例中，触控结构10可以形成为单独的元件，并且采用粘合层将触控结构10粘贴在发光基板20的封装层24上。在触控结构10形成单独的元件(例如单独的膜层)的情况下，触控结构10还可以包括用于承载触控电极的承载膜。
示例性的，承载膜可以为树脂膜、玻璃基底和复合膜中的至少一个。
示例性的，粘合层可以为压敏粘合剂(Pressure Sensitive Adhesive，简称PSA)、光学透明粘合剂(Optical Clear Adhesive，简称OCA)和光学透明树脂(Optical Clear Resin，简称OCR)中的至少一个。
在另一些实施例中，参阅图3，触控结构10可以直接设置在发光基板20上，例如直接设置在发光基板20的封装层24上，即，触控结构10和封装层24之间不设置其它膜层。示例性的，触控结构10可以通过连续工艺形成在发光基板20的封装层24上，即，触控结构10可以在发光基板20形成封装层24后，直接形成在封装层24的上方，利于制备得到更轻更薄的显示装置1000，具有较好的应用前景。
前述触控结构10除了可以通过手指进行触控外，还可以通过触控笔进行触控。
其中，触控笔可以包括主动式电容笔(即主动笔)和被动式电容笔(即被动笔)。
被动笔与手指一样，通过与触控结构10接触来改变触控结构10在接触位置处的电容，从而实现与手指一样的触控效果。
主动笔内设有自有的电路，触控结构10接收主动笔发射的信号，从而得知主动笔在显示屏上的坐标，实现触控效果。主动笔无需与触控结构10直接接触，即，主动笔可以实现悬浮触控。
相对于被动笔，主动笔兼具悬浮触控功能(可以避免显示屏受到触控笔的损伤)和开关控制功能(可以在不需要使用时关闭主动笔的自有电路，防止误触)，具有广泛的应用场景。
随着触控显示技术的发展，对主动笔的各项性能有了更高的要求。主动笔的性能可以包括精确度、线性度、信噪比以及悬浮高度等。
其中，精确度越高，主动笔的触控位置越准确。线性度越高，主动笔在触控结构10上画出的线条越精美，线条发生抖动的可能性越低。信噪比越高，即主动笔自有电路发出的信号，与环境噪声信号的比值越高，说明主动笔发出的实现触控的有效信号的比例越多，即环境噪声信号对触控的干扰较低，触控 效果较好。悬浮高度越高，且不同触控位置处的悬浮高度越均匀，主动笔的使用体验越好。
在一些实施例中，参阅图3，触控结构10铺设在发光基板20的出光侧之后，触控结构10与发光基板20中的导电结构具有正对面积，容易产生寄生电容。
例如，参阅图3，阴极层304为整层设计。触控结构10与阴极层304之间具有正对面积，当触控结构10有电流流通时，触控结构10会与阴极层304之间产生寄生电容(即噪声信号)，该寄生电容的值越大，则对主动笔发出的用于触控的信号的干扰越大，即主动笔的信噪比相对较低，触控芯片无法通过滤波将主动笔发出的信号与噪声信号区分开，导致主动笔的工作性能很差。
为了解决上述问题，本公开实施例提供了一种显示装置1000。
如图4所示，该显示装置1000的触控结构10包括触控区S5，及围绕触控区S5的扇出区S4、第一周边区S1、第二周边区S2和第三周边区S3。
其中，参阅图4，第一周边区S1和第二周边区S2沿第一方向X分别位于触控区S5的两侧，扇出区S4和第三周边区S3沿第二方向Y分别位于触控区S5的两侧。
前述第一方向X和第二方向Y相交叉。例如，第一方向X与第二方向Y可以相互垂直。
需要说明的是，第一方向X可以是显示装置1000的横向，第二方向Y可以是显示装置1000的纵向；或者，第一方向X可以是多个子像素P阵列式排列中的行方向，第二方向Y可以是多个子像素P阵列式排列中的列方向。
本公开的多个附图中仅以第一方向X为行方向，第二方向Y为列方向为例进行示意。在本公开的实施例中，通过将附图进行一定角度(例如30度、45度或90度等)的旋转所得到的技术方案亦在本公开的保护范围之内。
围绕触控区S5的扇出区S4、第一周边区S1、第二周边区S2和第三周边区S3被配置为供多条触控走线(包括图4所示的第一触控走线L1和第二触控走线L2)进行布线。其中，扇出区S4还被配置为，与前述柔性线路板200进行绑定连接，显示装置1000中的多条触控走线均最终延伸至扇出区S4，并在扇出区S4裸露，裸露的部分作为引脚便于与柔性线路板200进行绑定，从而使多条触控走线与柔性线路板200上的触控芯片300电连接，以便实现显示装置1000的触控功能。
参阅图4，前述触控区S5被配置为设置多个触控电极(包括如图4所示的第一触控电极Tx和第二触控电极Rx)，即，触控区S5为显示装置1000的触控结构10的有效触控区域。
其中，触控区S5包括第一子区S51、第二子区S52、第三子区S53和第四子区S54。
第一子区S51和第二子区S52沿第一方向X排列，第一子区S51和第三子区S53沿第二方向Y排列，第三子区S53和第四子区S54沿第一方向X排列。即，前述四个子区(第一子区S51、第二子区S52、第三子区S53和第四子区S54)沿第一方向X和第二方向Y呈阵列分布。
参阅图4，显示装置1000包括多个第一触控通道1和多个第二触控通道2。
需要说明的是，前述“第一触控通道1”为，触控结构10中，相互电连接的，且同时传输相同第一触控信号的多个第一触控电极Tx所组成的通道；前述“第二触控通道2”为，触控结构10中，相互电连接的，且同时传输相同第二触控信号的多个第二触控电极Rx所组成的通道。
每个第一触控通道1包括沿第一方向X排列且串接的多个第一触控电极Tx，每个第二触控通道2包括沿第二方向Y排列且串接的多个第二触控电极Rx。
示例性地，多个第一触控通道1和多个第二触控通道2之间相互绝缘。且多个第一触控通道1和多个第二触控通道2之间相互交叉，从而使得第一触控电极Tx和第二触控电极Rx绝缘且交替设置。
示例性地，如图4所示，第一触控电极Tx和第二触控电极Rx交替设置，相邻的不同触控电极之间(即第一触控电极Tx和第二触控电极Rx之间)绝缘且能够产生互容，这些触控电极在被触摸后互容值会发生变化，可以通过侦测互容值，确定互容值在触摸前后的变化量，进行触摸位置的判断，实现触控结构10的触控效果。
示例性地，如图5所示，显示装置1000的触控结构10包括多条金属线GL，多条金属线GL相互交叉形成多个金属网格G。
示例性地，如图5所示，在触控结构10中，触控电极(包括第一触控电极Tx和第二触控电极Rx)采用金属网格结构(即包括多个金属网格G)，相比于采用ITO(Indium Tin Oxide，氧化铟锡)形成面状电极作为触控电极，金属网格结构的触控电极的电阻小、灵敏度较高，能够提高触控结构10的触控灵敏度。且采用金属网格结构的触控电极机械强度高，能减小触控结构10 的重量，在触控结构10应用于显示装置1000中时，能够实现显示装置1000的轻薄化。
示例性地，如图5所示，第一触控电极Tx和第二触控电极Rx采用金属网格结构。第一触控电极Tx和第二触控电极Rx的金属网格G可以设置于同一膜层中，第一触控电极Tx的金属网格G与第二触控电极Rx的金属网格G断开，从而使得第一触控电极Tx和第二触控电极Rx相互绝缘。
需要说明的是，图5中金属网格G做不同的图案填充，是为了区分不同的触控电极，第一触控电极Tx和第二触控电极Rx的金属网格G可以采用相同材料，采用相同的工艺制程形成。
示例性地，如图5所示，第一触控电极Tx和第二触控电极Rx的形状为菱形或大致为菱形。其中，“大致为菱形”是指，触控电极(即第一触控电极Tx和第二触控电极Rx)的形状整体上呈菱形形状，但是并不局限为标准的菱形，例如触控电极的边界允许是非直线形的(例如锯齿形)，又如在后面的实施例中，所涉及的触控电极的形状整体呈菱形，但是其边界呈锯齿形。
并且，本公开实施例中第一触控电极Tx和第二触控电极Rx的电极图案形状不限于菱形或大致的菱形，例如还可以为矩形、长条形等。
示例性地，根据金属线GL的交叉方式的不同，一个金属网格G的形状可以大致呈六边形、矩形或不规则多边形。
参阅图4，每个子区(第一子区S51、第二子区S52、第三子区S53和第四子区S54)内均设有至少一个第一触控通道1和至少一个第二触控通道2，且位于同一子区内的至少一个第一触控通道1和至少一个第二触控通道2交叉设置且相互绝缘。
即，每个子区内均设有多个第一触控电极Tx和多个第二触控电极Rx，对应前述四个子区，显示装置1000的触控结构10被划分为四个触控屏幕(即触控结构10的四个子区所在的部分)。
示例性地，参阅图4，每个子区内均设有多个第一触控通道1和多个第二触控通道2，其中，多个第一触控通道1沿第二方向Y排列设置，每个第一触控通道1沿第一方向X延伸，多个第二触控通道2沿第一方向X排列设置，每个第二触控通道2沿第二方向Y延伸。
参阅图4和图6，位于不同子区的第一触控通道1相互绝缘，位于不同子区的第二触控通道2相互绝缘。
例如，参阅图6，位于不同子区的且相邻设置的两个第一触控通道1之间相互断开，位于不同子区的且相邻设置的两个第二触控通道2之间相互断开。 即，不同子区所对应的触控结构10的不同的部分之间相互绝缘，从而将触控结构10划分为四个触控屏幕。
参阅图4，显示装置1000还包括多条第一触控走线L1和多条第二触控走线L2。
多条第一触控走线L1与多个第一触控通道1电连接。示例性地，多条第一触控走线L1与多个第一触控通道1一一对应电连接，即，一条第一触控走线L1与一个第一触控通道1电连接。第一触控走线L1被配置为与第一触控通道1电连接，以便向第一触控通道1中的第一触控电极Tx传输触控信号。
多条第二触控走线L2与多个第二触控通道2电连接。示例性地，多条第二触控走线L2与多个第二触控通道2一一对应电连接，即，一条第二触控走线L2与一个第二触控通道2电连接。第二触控走线L2被配置为与第二触控通道2电连接，以便向第二触控通道2中的第二触控电极Rx传输触控信号。
参阅图4，第一子区S51和第三子区S53内的第一触控通道1连接的第一触控走线L1，由第一周边区S1延伸至扇出区S4。
例如，参阅图4，相对于第三子区S53，第一子区S51更靠近第三周边区S3。与第一子区S51内的第一触控通道1电连接的第一触控走线L1，由第一周边区S1的靠近第三周边区S3的部分引出，并沿着第一周边区S1延伸至扇出区S4，最终通过扇出区S4与柔性线路板200进行绑定连接；与第三子区S53内的第一触控通道1电连接的第一触控走线L1，由第一周边区S1的远离第三周边区S3的部分引出，并沿着第一周边区S1延伸至扇出区S4，最终通过扇出区S4与柔性线路板200进行绑定连接。
示例性地，参阅图4，相对于第三子区S53内的第一触控通道1连接的第一触控走线L1在第一周边区S1的部分，第一子区S51内的第一触控通道1连接的第一触控走线L1在第一周边区S1的部分远离触控区S5，从而避免第一子区S51内的第一触控通道1连接的第一触控走线L1，和第三子区S53内的第一触控通道1连接的第一触控走线L1，在第一周边区S1交叉，从而优化布线空间。
参阅图4，第二子区S52和第四子区S54内的第一触控通道1连接的第一触控走线L1，由第二周边区S2延伸至扇出区S4。
例如，参阅图4，相对于第四子区S54，第二子区S52更靠近第三周边区S3。与第二子区S52内的第一触控通道1电连接的第一触控走线L1，由第二周边区S2的靠近第三周边区S3的部分引出，并沿着第二周边区S2延伸至扇出区S4，最终通过扇出区S4与柔性线路板200进行绑定连接；与第四子区 S54内的第一触控通道1电连接的第一触控走线L1，由第二周边区S2的远离第三周边区S3的部分引出，并沿着第二周边区S2延伸至扇出区S4，最终通过扇出区S4与柔性线路板200进行绑定连接。
示例性地，参阅图4，相对于第四子区S54内的第一触控通道1连接的第一触控走线L1在第二周边区S2的部分，第二子区S52内的第一触控通道1连接的第一触控走线L1在第二周边区S2的部分远离触控区S5，从而避免第二子区S52内的第一触控通道1连接的第一触控走线L1，和第四子区S54内的第一触控通道1连接的第一触控走线L1，在第二周边区S2交叉，从而优化布线空间。
参阅图4，第一子区S51内的第二触控通道2连接的第二触控走线L2，从第三周边区S3引出，并经第一周边区S1延伸至扇出区S4，最终通过扇出区S4与柔性线路板200进行绑定连接。

第三子区S53和第四子区S54内的第二触控通道2电连接的第二触控走线L2，直接延伸至扇出区S4，最终通过扇出区S4与柔性线路板200进行绑定连接。
示例性地，参阅图4，相对于第一触控通道1连接的第一触控走线L1在第一周边区S1的部分，第一子区S51内的第二触控通道2连接的第二触控走线L2在第一周边区S1的部分远离触控区S5，避免在第一周边区S1内的第一触控走线L1和第二触控走线L2交叉，从而优化布线空间。
示例性地，参阅图4，相对于第一触控通道1连接的第一触控走线L1在第二周边区S2的部分，第二子区S52内的第二触控通道2连接的第二触控走线L2在第二周边区S2的部分远离触控区S5，避免在第二周边区S2内的第一触控走线L1和第二触控走线L2交叉，从而优化布线空间。
参阅图4，显示装置1000还包括第一触控芯片300A和第二触控芯片300B。
任意两个子区内的，第一触控通道1连接的第一触控走线L1及第二触控通道2连接的第二触控走线L2，与第一触控芯片300A电连接。除该任意两个子区外的其余两个子区内的，第一触控通道1连接的第一触控走线L1及第二触控通道2连接的所述第二触控走线L2，与第二触控芯片300B电连接。
即，第一触控芯片300A被配置为，向前述任意两个子区内的触控电极(包括第一触控电极Tx和第二触控电极Rx)传输触控信号，第二触控芯片300B 被配置为，向前述其余两个子区内的触控电极传输触控信号。
需要说明的是，前述“任意两个子区”为，第一子区S51、第二子区S52、第三子区S53和第四子区S54中的任意两个，例如，为第一子区S51和第二子区S52；前述“其余两个子区”为，第一子区S51、第二子区S52、第三子区S53和第四子区S54中的，除前述任意两个子区外，剩余的两个子区，例如为第三子区S53和第四子区S54。
示例性地，在另一些实施例中，每个触控芯片(包括第一触控芯片300A和第二触控芯片300B)可以包括至少一个插口，每个插口对应同一个子区内的触控通道(包括第一触控通道1和第二触控通道2)所连接的触控走线(包括第一触控走线L1和第二触控走线L2)，即，子区与插口一一对应，不同的子区分别对应不同的插口，从而便于触控芯片对不同的子区实现分区控制。
在相关技术中，如图7所示，触控结构10’为整屏设置，该触控结构10’中包括多个第一触控通道1’和多个第二触控通道2’，该多个第一触控通道1’沿第二方向Y’排列，每个第一触控通道1’沿第一方向X’延伸，该多个第二触控通道2’沿第一方向X’排列，每个第二触控通道2’沿第二方向Y延伸。
经本公开发明人研究发现，整屏设置的触控结构10’中，触控通道(第一触控通道1’或第二触控通道2’)的面积较大，即，触控通道与发光基板的导电结构(例如阴极层304)之间的正对面积较大，则触控通道与发光基板的导电结构之间的寄生电容较大，即产生的噪声信号的强度较强，容易干扰主动笔发出的信号的传递和被接收效率，影响主动笔进行触控时的触控性能。
尤其在大尺寸显示装置中，显示装置1000的尺寸越大，整屏设置的触控结构10’中的触控通道的面积就越大，则触控通道与发光基板的导电结构之间的寄生电容越大，噪声信号强度越强，则对主动笔的触控效果影响非常大。
本公开实施例提供的显示装置1000，通过将触控区S5划分为第一子区S51、第二子区S52、第三子区S53和第四子区S54，并设置该四个子区中不同子区内的触控通道(包括第一触控通道Tx和第二触控通道Rx)相互绝缘，从而将触控结构10划分为四个触控屏幕，相对于整屏设置的触控结构10’，该四个触控屏幕中，每个触控屏幕的面积均大致为整屏设置的触控结构10’的面积的四分之一，每个子区内的触控通道的面积，均大致为整屏设置的触控通道的面积的二分之一，例如，参阅图4，第一子区S51内的第一触控通道1的面积，大致为整屏设置的触控结构10’中的第一触控通道1’的面积(参阅图7)的二分之一。
通过前述设计，可以在不减少触控结构10的有效触控面积，保证触控效 果的前提下，减小每个触控电极(第一触控电极Tx或第二触控电极Rx)所在的触控通道的面积，即，减小每个触控电极所在的触控通道与发光基板20的导电结构(例如阴极层304)之间的寄生电容(即触控电极的自容值)，从而减小每个触控电极所在位置处的噪声信号的强度，即，提高主动笔在该触控电极所在位置处进行触控时的信噪比，提升主动笔在触控过程中的触控效果，加强显示装置1000，尤其大尺寸显示装置与主动笔的配适性，拓宽了主动笔的应用市场，例如，拓展了主动笔在大尺寸显示装置中的应用。
此外，本公开实施例提供的显示装置1000，通过设置第一触控芯片300A和第二触控芯片300B，并设置任意两个子区中的触控通道与第一触控芯片300A电连接，其余两个子区中的触控通道与第二触控芯片300B电连接，可以在实现降低主动笔信噪比的效果的同时，避免一个触控芯片控制整屏触控结构10’的情况下触控芯片负载较大的问题，即，减少单个触控芯片(包括第一触控芯片300A和第二触控芯片300B)的负载，延长显示装置1000的使用寿命。
在一些实施例中，如图4所示，位于不同子区内的第一触控通道1的沿第一方向X的尺寸大致相等。位于不同子区内的第二触控通道2的沿第二方向Y的尺寸大致相等。即，前述四个子区内的第一触控通道1的长度大致相等，前述四个子区内的第二触控通道2的长度大致相等。
在一些实施例中，如图4所示，位于不同子区内的第一触控通道1的沿第二方向Y的尺寸大致相等。位于不同子区内的第二触控通道2的沿第一方向X的尺寸大致相等。即，前述四个子区内的第一触控通道1的宽度大致相等，前述四个子区内的第二触控通道2的宽度大致相等。
通过设置不同子区内的触控通道的长度和宽度大致相同，即设置不同子区内的触控通道的面积大致相同，使得不同子区内的触控通道与发光基板的导电结构(例如阴极层304)之间的寄生电容大致相同，从而使得主动笔在不同子区内进行触控时的信噪比大致相同，即，使得主动笔在不同子区内的悬浮高度以及触控灵敏度大致均一，提高显示装置1000的触控效果。

即，分属于不同子区且沿第一方向X相邻设置的两个第一触控通道1的中心可以处于同一条直线上。
通过前述设置，可以保证被前述四个子区分割后的触控结构10中，多个第一触控通道1在第一方向X和第二方向Y上呈阵列分布，从而使得第一触控电极Tx在触控结构10上均匀分布，可以使得触控结构10不同位置处的触控效果大致相同，提高主动笔在触控过程中的使用体验。
示例性地，参阅图4，分别位于第一子区S51和第二子区S52内，且相邻设置的两个第一触控通道1内的所有第一触控电极Tx的中心，大致处于沿第一方向X延伸的同一直线(如图4所示的直线La)上。同理，分别位于第三子区S53和第四子区S54内，且相邻设置的两个第一触控通道1内的所有第一触控电极Tx的中心，大致处于沿第一方向X延伸的同一直线上。进一步保证第一触控电极Tx在触控结构10上均匀分布，从而提高主动笔在触控过程中的使用体验。

示例性地，参阅图4，分别位于第一子区S51和第三子区S53内，且相邻设置的两个第二触控通道2内的所有第二触控电极Rx的中心，大致处于沿第二方向Y延伸的同一直线(如图4所示的直线Lb)上。同理，分别位于第二子区S52和第四子区S54内，且相邻设置的两个第二触控通道2内的所有第二触控电极Rx的中心，大致处于沿第二方向Y延伸的同一直线上。进一步保证第二触控电极Rx在触控结构10上均匀分布，从而提高主动笔在触控过程中的使用体验。

在一些实施例中，前述显示装置1000的触控结构10为金属网格结构(参阅图5和图8)，触控结构10一体成型后，在需要绝缘的位置处将金属网格G断开，例如，在两个子区的相邻且相互靠近的边界处断开，具体地，在分属 于不同子区，且相邻设置的两个第一触控通道1之间，或两个第二触控通道2之间将金属网格断开，从而将触控结构10划分为四个相互绝缘的触控屏幕。
示例性地，不同的第一触控通道1之间，以及不同的第二触控通道2之间，均相互绝缘(例如通过断开金属网格G实现绝缘)。
示例性地，相邻设置的第一触控电极Tx和第二触控电极Rx之间也相互绝缘。
在一些实施例中，如图8所示，分属于不同子区内，且沿第一方向X相邻设置的两个第一触控通道1之间，以及分属于不同子区内，且沿第二方向Y相邻设置的两个第二触控通道2之间均具有间隙(例如图8中的虚线Lc所示意的路径)，该间隙呈折线状延伸。
示例性地，参阅图8，该间隙由该两个第一触控通道1之间，以及该两个第二触控通道2之间的金属网格线GL断开后形成。示例性地，该间隙被配置为，使得该两个第一触控通道1之间，以及该两个第二触控通道2之间相互绝缘。
示例性地，任意需要断开的位置，例如相邻的第一触控电极Tx和第二触控电极Rx之间的金属网格线GL断开后形成的间隙均呈折线状延伸。
通过设置间隙为折线状，使得触控结构10被四个子区划分为四个触控屏幕后，相邻子区之间的划分界限较为参差，避免由于通过长距离直线断线进行分区导致的相邻子区之间出现明显的线痕的问题，即避免显示装置1000在显示过程中出现消影问题，提高显示装置1000的显示效果。

通过设置第一触控芯片300A和第二触控芯片300B分别控制两个子区内的触控通道(包括第一触控通道1和第二触控通道2)，使得分割为四个触控 屏幕后的触控结构10实现触控，同时可以减小单个触控芯片的负载，提高显示装置1000的使用寿命。
在前述实施例的基础上，在一些实施例中，如图4所示，第一触控芯片300A和第二触控芯片300B均位于扇出区S4远离第三周边区S3的一侧，在第二方向Y上，相对于第一触控芯片300A，第二触控芯片300B更靠近扇出区S4。
示例性地，参阅图4，第一触控芯片300A和第二触控芯片300B设于柔性线路板200上，在柔性线路板200与显示面板100绑定连接后，且柔性线路板200弯折之前，第一触控芯片300A和第二触控芯片300B位于扇出区S4远离第三周边区S3的一侧。
参阅图4，在第二方向Y上，相对于第一子区S51和第二子区S52，第三子区S53和第四子区S54更靠近扇出区S4，通过设置第二触控芯片300B更靠近扇出区S4，使得与第二触控芯片300B对应电连接的第三子区S53、第四子区S54引出的触控走线，相对于与第一触控芯片300A对应电连接的第一子区S51、第二子区S52引出的触控走线，更靠近触控区S5，从而可以避免第一子区S51、第二子区S52引出的触控走线和第三子区S53、第四子区S54引出的触控走线发生交叉，从而优化布线空间，降低布线难度，且利于实现显示装置1000的轻薄化。
需要说明的是，本公开提供的显示装置1000并不仅限于上述实施例所述的触控芯片的布置方式和连接方式，例如，第一触控芯片300A还可以与第一子区S51和第三子区S53内的第一触控通道1连接的第一触控走线L1及第二触控通道2连接的第二触控走线L2电连接，第二触控芯片300B与第二子区S52和第四子区S54内的第一触控通道1连接的第一触控走线L1及第二触控通道2连接的第二触控走线L2电连接。
示例性地，在第一触控芯片300A与第一子区S51和第三子区S53对应电连接、第二触控芯片300B与第二子区S52和第四子区S54对应电连接的情况下，在第一方向X上，相对于第一触控芯片300A，第二触控芯片300B更靠近第二周边区S2，从而避免触控走线相互交叉，优化布线空间。
在一些实施例中，如图4所示，相对于第二触控走线L2的位于第一周边区S1的部分，第一触控走线L1的位于第一周边区S1的部分更靠近触控区S5设置；相对于第二触控走线L2的位于第二周边区S2的部分，第一触控走线L1的位于第二周边区S2的部分更靠近触控区S5设置。
参阅图4，第一子区S51和第二子区S52中引出的第二触控走线L2分别 经过第一周边区S1和第二周边区S2，并最终延伸至扇出区S4，通过前述设置，可以避免第一触控走线L1和第二触控走线L2发生交叉，从而优化布线空间，降低布线难度。
在一些实施例中，如图9所示，显示装置1000还包括第一虚拟电极3。示例性地，显示装置1000的触控结构10中包括该第一虚拟电极3。
参阅图9和图10，该第一虚拟电极3设于相邻的第一触控电极Tx和第二触控电极Rx之间，且与该第一触控电极Tx和该第二触控电极Rx相互绝缘。
示例性地，参阅图10，第一触控电极Tx、第二触控电极Rx以及第一虚拟电极3均为金属网格结构。
示例性地，第一触控电极Tx、第二触控电极Rx以及第一虚拟电极3一体成型后，在需要绝缘的位置处将金属网格线GL断开，例如，参阅图10，将第一触控电极Tx和相邻的第一虚拟电极3之间的金属网格线GL断开，实现第一触控电极Tx和第一虚拟电极3的绝缘。
参阅图10，第一虚拟电极3的靠近第一触控电极Tx的边界和靠近第二触控电极Rx的边界为折线状，且第一虚拟电极3和第一触控电极Tx的相互靠近的边界形状相适配，第一虚拟电极3和第二触控电极Rx的相互靠近的边界形状相适配。
即，第一触控电极Tx和第二触控电极Rx之间的间隙的形状与第一虚拟电极3的形状相适配，例如，第一虚拟电极3大致填充于第一触控电极Tx和第二触控电极Rx之间的间隙内。
通过设置第一虚拟电极3，并设置第一虚拟电极3的边界与靠近该第一虚拟电极3的触控电极(包括第一触控电极Tx和第二触控电极Rx)的边界相适配，使得第一虚拟电极3大致填充于第一触控电极Tx和第二触控电极Rx之间的间隙内，从而在触控结构10整屏尺寸不变的情况下，减小第一触控电极Tx和第二触控电极Rx的面积，从而可以减小触控结构10整体的初始互容值(手指未进行触摸时触控结构10的互容值)，从而可以提高触控结构10的触控灵敏度，优化触控效果。还可以减少触控结构10的产热量，从而避免显示装置1000由于温度变化受到较大的损耗，例如，避免显示装置1000中的某些材料，例如偏光片500等结构在温度变化较大的情况下出现的鬼点问题。此外，减少触控电极的面积后，可以减少触控电极与阴极层304之间的寄生电容，从而提高主动笔的信噪比，进一步优化主动笔的触控效果。
在一些实施例中，如图9和图11所示，第一虚拟电极3为中心对称 图形。即，第一虚拟电极3的靠近第一触控电极Tx的边界，和靠近第二触控电极Rx的边界大致对称，使得第一触控电极Tx和第二触控电极Rx的形状大致相同，从而使得触控结构10中的触控电极的布置较为规律。
在前述实施例的基础上，在一些实施例中，如图11所示，与第一虚拟电极3相邻的第一触控电极Tx的中心，和与第一虚拟电极3相邻的第二触控电极Rx的中心的连线(参阅图11中的虚线Gd)的中点，与第一虚拟电极3的中心重合。从而使得第一触控电极Tx和第二触控电极Rx的面积大致相同，则触控结构10不同位置处的噪声信号较为均一，使得主动笔在触控过程中不同位置处的信噪比大致相同，优化主动笔的触控性能，例如，使得主动笔的悬浮高度较为均一。
需要说明的是，前述“中心”可以为几何中心，例如，第一虚拟电极3的中心即为第一虚拟电极3的几何中心。
示例性地，第一虚拟电极3以自身的中心为对称中心呈中心对称设置。

通过设置条形的多个延伸部3’，并设置任意相邻两个延伸部3’的延伸方向相交叉，使得第一虚拟电极3的整体形状呈折线形，可以使第一虚拟电极3与触控电极之间的金属网格线GL断开后形成的边界较为参差，避免由于长距离直线断线导致第一虚拟电极3与触控电极之间出现明显的线痕的问题，即避免显示装置1000在显示过程中出现消影问题，提高显示装置1000的显示效果。
在一些实施例中，如图11所示，第一虚拟电极3包括第一延伸部31，及分设于第一延伸部31两端且与第一延伸部31相连的两个第二延伸部32，第一延伸部31大致沿第二方向Y延伸，第二延伸部32大致沿第一方向X延伸。
即，第一虚拟电极3整体大致呈“Z”字型，通过设置“Z”字型第一虚拟电极3，使得第一触控电极Tx和第二触控电极Rx的边界大致呈“Z”字型，可以在避免显示装置1000在显示过程中出现消影问题的同时，还可以避免触控电极的边界过于参差导致主动笔在触控过程中出现 抖动的情况，即，可以同时兼顾避免消影问题的效果和提高主动笔的线性度的效果。
在一些实施例中，多个延伸部3’的长度大致相等。例如，第一延伸部31在第二方向Y上的尺寸，和第二延伸部32在第一方向X上的尺寸大致相等，从而使得第一虚拟电极3呈规则图形，使得与第一虚拟电极3相适配的触控电极的形状大致相同，且还可以降低触控结构10的制备难度。
在一些实施例中，第一虚拟电极3呈条形，沿第一虚拟电极3的长度延伸方向，第一虚拟电极在不同位置处的宽度大致相等。例如，第一延伸部31在第一方向X上的尺寸，和第二延伸部32在第二方向Y上的尺寸大致相等，从而进一步使得第一虚拟电极3呈规则图形，使得与第一虚拟电极3相适配的触控电极的形状大致相同，且还可以降低触控结构10的制备难度。

根据前述实施例，可以使得第一触控电极Tx和第二触控电极Rx的形状和面积大致相同，从而使得触控结构10不同位置处的噪声信号大致相同，则主动笔在触控过程中在触控结构10不同位置处的信噪比大致相同，可以提高主动笔的触控性能，例如，使得主动笔的悬浮高度较为均一。
示例性地，每个触控电极的周围均设有四个第一虚拟电极3。

示例性地，第一凸起部C1和第二凸起部C2的尺寸和形状大致相同。
通过前述实施例，使得第一触控电极Tx和第二触控电极Rx均大致呈“十”字型，可以保证第一触控电极Tx和第二触控电极Rx的边界的折角较少，从而一方面保证主动笔在该显示装置1000上进行触控时的线性度，另一方面避免边界由于长距离直线断线导致的消影问题。
在一些实施例中，如图9所示，显示装置1000还包括第二虚拟电极4。示例性地，显示装置1000的触控结构10包括该第二虚拟电极4。
该第二虚拟电极4设于相邻且分属于不同的第一触控通道1的两个第一触控电极Tx之间，并设于相邻且分属于不同的第二触控通道2的两个第二触控电极Rx之间。第二虚拟电极4与第一触控电极Tx和第二触控电极Rx相互绝缘。即，第二虚拟电极4被配置为，与第一虚拟电极3一起围绕触控电极，从而将第一触控电极Tx和第二触控电极Rx间隔开来。
示例性地，第二虚拟电极4可以与第一虚拟电极3连接。
示例性地，第二虚拟电极4呈金属网格状。
示例性地，如图9所示，第二虚拟电极4呈矩形。
在上述将触控结构10划分为四个触控屏幕的实施例，以及设置第一虚拟电极3和第二虚拟电极4的实施例的基础上，本公开还提供了一种可以提升主动笔的触控精确度的显示装置1000。
在一些实施例中，如图13所示，至少一个第一触控通道1包括多个第一子通道1A，多个第一子通道1A沿第二方向Y排列，每个第一子通道1A沿第一方向X延伸，且第一子通道1A包括电连接的多个第一触控电极Tx。例如，参阅图13，一个第一触控通道1包括两个第一子通道1A。例如，参阅图14，一个第一触控通道1包括四个第一子通道1A。
如图13所示，至少一个第二触控通道2包括多个第二子通道2A，多个第二子通道2A沿第一方向X排列，每个第二子通道2A沿第二方向Y延伸，且第二子通道2A包括电连接的多个第二触控电极Tx。例如，参阅图13，一个第二触控通道2包括两个第二子通道2A。例如，参阅图14，一个第二触控通道2包括四个第二子通道2A。
在前述实施方式的基础上，同一第一触控通道1包括的多个第一子通道1A电连接。同一第二触控通道2包括的多个第二子通道2A电连接。
示例性地，参阅图14，同一第一触控通道1中，分属于不同且相邻的两个第一子通道1A中的两个第一触控电极Tx之间电连接，从而实现同一第一 触控通道1中的多个第一子通道1A电连接的目的。
示例性地，同一第一触控通道1中，相邻两个第一子通道1A，可以与同一条触控线M电连接，从而实现同一第一触控通道1中的多个第一子通道1A电连接的目的。

参阅图14，在本公开实施例提供的显示装置1000中，第一触控通道1位于沿第一方向X延伸的第一矩形区域，第二触控通道2位于沿第二方向Y延伸的第二矩形区域。
需要说明的是，前述“第一矩形区域”为第一触控通道1中第一触控电极Tx所在的区域，具体的，第一矩形区域为，能够囊括同一个第一触控通道1中全部第一触控电极Tx的面积最小的矩形区域。前述“第二矩形区域”为第二触控通道2中第二触控电极Rx所在的区域，具体的，第二矩形区域为，能够囊括同一个第二触控通道2中全部第二触控电极Rx的面积最小的矩形区域。
参阅图14，第一矩形区域和第二矩形区域相交叉的矩形区域为触控单元区域J。即，触控单元区域J为第一触控通道1和第二触控通道2的交叉区域。
参阅图14，触控单元区域J中，第一子通道1A和第二子通道2A的交叉位置可以为一个触控点M1。
在相关技术中，如图7所示，显示装置1000’的每个触控通道(第一触控通道1’或第二触控通道2’)中均仅设置一个子通道(第一子通道1A’或第二子通道2A’)。参阅图7，一个第一触控通道1’和一个第二触控通道2’相交叉的位置为一个触控点M1’，一个触控单元区域J’内仅有一个交叉位置，即只有一个触控点M1’，当手指触摸该触控单元区域J’时，交叉位置处的触控电极会发生互容值的变化，从而检测到手指的触摸位置，实现触控结构10’的触控功能。
在相关技术中，触控结构10’中触控单元区域J’的面积大小与手指的大小相适配，例如，一个触控单元区域J’的面积大致为4×4mm2，与手指进行触控时，手指与屏幕的接触面积大致相同，从而使得手指出口明时的精确度较高。
然而，经本公开发明人研究发现，主动笔的笔头尺寸较小，例如，主动笔 的笔头尺寸大致为手指的四分之一甚至更小(例如主动笔的笔头尺寸为1mm)，当主动笔应用于相关技术中的显示装置1000’中时，触控单元区域J’的面积远远大于主动笔笔头的尺寸，主动笔的准确度会急剧下降，不利于主动笔的应用。
本公开实施例提供的触控结构10中，通过在至少一个触控通道(包括第一触控通道1和第二触控通道2)内设置相邻的多个子触控通道(包括第一子通道1A和第二子通道2A)，并设置同一触控通道中的多个子触控通道之间电连接，从而使得触控单元区域J内包括多个第一子通道1A和多个第二子通道2A之间的多个交叉位置，即，使得触控单元区域J内包括多个触控点M1，从而可以在不改变触控结构10中触控单元区域J的面积，从而保障手指触控与显示装置1000的适配度的同时，在触控单元区域J内划分多个与主动笔的笔头尺寸相适配的触控点M1，极大地提升了主动笔的准确度，兼顾了主动笔在显示装置1000中的触控功能。

在第三连接部B3与第四连接部B4的交叉位置处，利用绝缘层10B将第三连接部B3与第四连接部B4隔开，从而在实现同一触控通道中的触控电极电连接的同时，避免在交叉位置处发生电导通，导致第一触控电极Tx和第二触控电极Rx上传输的触控信号发生串扰的问题。
示例性地，如图20所示，第三连接部B3位于第一导电层10A，第四连接部B4位于第二导电层10C。

示例性地，第三连接部B3与第四连接部B4均为金属网格结构。
对比图7和图14所示，触控结构10的一个触控单元区域J中，第三连接部B3和第四连接部B4所组成的连接结构的数量相较于相关技术中的连接结构的数量多，即，金属网格线GL较多，可以有效地降低触控结构10的电阻。
在示例性实施例中，参阅图17，第一触控通道1包括多个第一连接部B1，同一第一触控通道1中，沿第二方向Y相邻两个第一触控电极Tx之间通过第一连接部B1电连接。第二触控通道2还包括第二连接部B2，同一第二触控通道2中，沿第一方向X相邻两个第二触控电极Rx之间通过第二连接部B2电连接。
参阅图17，至少一个第一连接部B1和至少一个第二连接部B2相交叉。
在第一连接部B1与第二连接部B2的交叉位置处，利用绝缘层10B将第一连接部B1与第二连接部B2隔开，从而在实现同一触控通道中的触控电极电连接的同时，避免在交叉位置处发生电导通，导致第一触控电极Tx和第二触控电极Rx上传输的触控信号发生串扰的问题。
示例性地，如图18所示，第一连接部B1位于第一导电层10A，第二连接部B2位于第二导电层10C。
其中，第一连接部B1与第一触控电极Tx一体设置。绝缘层10B中设有过孔H，第二连接部B2通过过孔H与第二触控电极Rx电连接。
示例性地，第一连接部B1也可以位于第二导电层10C，相应地第二连接 部B2位于第一导电层10A。
其中，第二连接部B2与第二触控电极Rx一体设置。绝缘层10B中设有过孔H，第一连接部B1通过过孔H与第一触控电极Tx电连接。
示例性地，第一连接部B1与第二连接部B2均为金属网格结构。
示例性地，触控结构10的触控单元区域J中，第一连接部B1和第二连接部B2所组成的连接结构的数量相较于相关技术中的来连接结构的数量多，即，金属网格线GL较多，可以有效地降低触控结构10的电阻。
在另一些实施例中，如图21所示，第一触控通道1位于沿第一方向X延伸的第一矩形区域，第二触控通道2位于沿第二方向Y延伸的第二矩形区域，第一矩形区域和第二矩形区域相交叉的矩形区域为触控单元区域J。
参阅图22，触控单元区域J内设有多个第一电极组O1和多个第二电极组O2，每个第一电极组O1包括沿第一方向X依次电连接的多个第一触控电极Tx，每个第二电极组O2包括沿第二方向Y依次电连接的多个第二触控电极Rx。多个第一电极组O1分属于同一第一触控通道1的多个第一子通道1A，多个第二电极组O2分属于同一第二触控通道2的多个第二子通道2A。
即，该多个第一电极组O1为多个第一子通道1A中位于该触控单元区域J的部分，该多个第二电极组O2为多个第二子通道2A中位于该触控单元区域J的部分。
参阅图22，多个第一电极组O1中位于触控单元区域J同侧边缘的多个第一触控电极Tx为多个第一设定电极O1’，多个第一设定电极O1’沿第二方向Y串联。多个第二电极组O2中位于触控单元区域J同侧边缘的多个第二触控电极Rx为多个第二设定电极O2’，多个第二设定电极O2’沿第一方向X串联。
示例性地，可以通过去除触控单元区域J的边缘处的第二虚拟电极4实现多个第一设定电极O1’沿第二方向Y串联，以及实现多个第二设定电极O2’沿第一方向X串联。
需要说明的是，该触控单元区域J内仅包括前述第一设定电极O1’的一半，以及仅包括前述第二设定电极O2’的一半。
通过将触控单元区域J边缘处的触控电极电连接，在实现同一触控通道中的多个子通道电连接的同时，可以按照触控单元区域J的划分对多个子通道进行电连接，避免显示装置1000不同位置处的自容值变化较大，例如，避免随意去除第二虚拟电极4导致的不同触控单元区域J内的自容值不同的问题。
在一些实施例中，如图22所示，在显示装置1000还包括第一连接部B1和第二连接部B2的情况下，多个第一设定电极O1’之间通过第一连接部B1串联，多个第二设定电极O2’之间通过第二连接部B2串联。
其中，第一连接部B1和第二连接部B2设于同一导电层。例如，第一连接部B1和第二连接部B2均设于第一导电层10A。
示例性地，参阅图22，第一连接部B1可以与第一设定电极O1’一体成型，第二连接部B2可以与第二设定电极O2’一体成型。
本公开发明人对本公开一些实施例提供的显示装置1000进行了触控效果的分析。
实验组：参阅图21，本公开实施例提供的显示装置1000中包括第一虚拟电极3，且一个触控通道(包括第一触控通道1和第二触控通道2)包括多个子通道(包括第一子通道1A和第二子通道2A)。
对照组：参阅图7，在相关技术中，一个触控通道包括一个子通道。
分析结果如下：
表1
其中，“初始互容值”为，手指没有触摸屏幕时，触控结构10的互容值。“触摸互容值”为，手指触碰屏幕进行触控时，触控结构10的互容值。“互容值的变化量”为初始互容值与触摸互容值的差值。“互容值变化量的占比”为互容值的变化量相对于初始互容值的占比。
互容值变化量的占比越高，则说明手指触碰屏幕时触控结构10的感应能力越强，即，说明触控结构10的触控灵敏度越高，触控效果越好。
通过表1可知，本公开实施例提供的显示装置1000中，在互容值的变化 量不变的情况下，降低了初始互容值，从而提高了互容值变化量的占比，也即提升了触控灵敏度。同时，本公开实施例还降低了触控电极的自容值(包括触控电极与阴极层产生的寄生电容)，有效地提高了主动笔在触控过程中的信噪比，优化主动笔的触控效果。同时，本公开实施例还大幅降低了触控电极的电阻，可以有效地降低主动笔发出的信号的衰减，同时降低触控结构10的负载，进一步优化触控效果。
综上所述，本公开实施例提供的显示装置1000，降低了初始互容值、触控电极的自容值以及电阻值，从而大幅提升了主动笔在触控过程中的灵敏度、信噪比等性能，优化触控效果。
参阅图23，本公开发明人对实验组中触控单元区域J内的触控点(①～⑨)进行触控效果的分析，分析过程中，以相关技术中的显示装置1000’对应的触控点(①～⑨)作为对照组。
需要说明的是，实验组中的触控单元区域J和对照组中的触控单元区域J’的尺寸大致相同。
分析结果如下：
表2
其中，“F1”为，主动笔在显示装置1000中的触控点进行触控时，主动笔与第一触控电极Tx之间的耦合电容，“F2”为，主动笔在显示装置1000中的触控点进行触控时，主动笔与第二触控电极Rx之间的耦合电容。
参阅表2，在相关技术中(即对照组)，在不同位置处，例如在触控点①和触控点②处，主动笔与触控电极之间的耦合电容相差较大，此外，在相同位置处，第一触控电极Tx与主动笔之间的耦合电容，与第二触控电极Rx与主动笔之间的耦合电容相差也较大，导致主动笔在触控过程中的线性度较差，主动笔在不同触控点处发出的信号的衰减量也不同，导致主动笔不同位置处的悬浮高度不同，影响触控体验。
通过表2可知，本公开实施例提供的显示装置1000中，例如在触控点①和触控点②处，主动笔与触控电极之间的耦合电容大致相同，例如在触控点②和触控点③处，主动笔与触控电极之间的耦合电容相差值也减少，在相同位置处，例如在触控点①处，第一触控电极Tx与主动笔之间的耦合电容，与第二触控电极Rx与主动笔之间的耦合电容大致相同。
综上所述，本公开实施例提供的显示装置1000，可以有效提升主动笔在触控过程中的线性度，还可以使主动笔在不同位置处的信号量大致均一，悬浮高度大致均一，提升了主动笔的触控体验。
本公开实施例还提供了一种触控结构10，如图24所示，该触控结构10包括多个第一触控通道1、多个第二触控通道2和第一虚拟电极3。
多个第一触控通道1中，每个第一触控通道1沿第一方向X延伸，每个第一触控通道1包括沿第一方向X依次排列的多个第一触控电极Tx，相邻两个第一触控电极Tx之间电连接。
多个第二触控通道2中，每个第二触控通道2沿第二方向Y延伸，每个第二触控通道2包括沿第二方向Y依次排列的多个第二触控电极Rx，相邻两个第二触控电极Rx之间电连接。
第一触控通道1和第二触控通道2相互交叉且相互绝缘。从而使得第一触控电极Tx和第二触控电极Rx相互绝缘。
第一方向X和第二方向Y相互交叉。例如，第一方向X与第二方向Y可以相互垂直。
示例性地，触控结构10包括多条金属线GL，多条金属线GL相互交叉形成多个金属网格G。
参阅图24，该第一虚拟电极3设于相邻的第一触控电极Tx和第二触控电极Rx之间，且与该第一触控电极Tx和该第二触控电极Rx相互绝缘。
示例性地，第一触控电极Tx、第二触控电极Rx以及第一虚拟电极3均为金属网格结构。
参阅图24，第一虚拟电极3的靠近第一触控电极Tx的边界和靠近第二 触控电极Rx的边界为折线状，且第一虚拟电极3和第一触控电极Tx的相互靠近的边界形状相适配，第一虚拟电极3和第二触控电极Rx的相互靠近的边界形状相适配。
即，第一触控电极Tx和第二触控电极Rx之间的间隙的形状与第一虚拟电极3的形状相适配，例如，第一虚拟电极3大致填充于第一触控电极Tx和第二触控电极Rx之间的间隙内。
通过设置第一虚拟电极3，并设置第一虚拟电极3的边界与靠近该第一虚拟电极3的触控电极(包括第一触控电极Tx和第二触控电极Rx)的边界相适配，使得第一虚拟电极3大致填充于第一触控电极Tx和第二触控电极Rx之间的间隙内，从而在触控结构10整屏尺寸不变的情况下，减小第一触控电极Tx和第二触控电极Rx的面积，从而可以减小触控结构10整体的初始互容值(手指未进行触摸时触控结构10的互容值)，从而可以提高触控结构10的触控灵敏度，优化触控效果。还可以减少触控结构10的产热量，从而避免显示装置1000由于温度变化受到较大的损耗，例如，避免显示装置1000中的某些材料，例如偏光片500等结构在温度变化较大的情况下出现的鬼点问题。此外，减少触控电极的面积后，可以减少触控电极与阴极层304之间的寄生电容，从而提高主动笔的信噪比，进一步优化主动笔的触控效果。
在一些实施例中，如图24所示，第一虚拟电极3包括依次相连的多个延伸部3’，每个延伸部3’呈条形，任意相邻两个延伸部3’的延伸方向相交叉。
示例性地，如图24所示，第一虚拟电极3呈“Z”字型。
通过设置条形的多个延伸部3’，并设置任意相邻两个延伸部3’的延伸方向相交叉，使得第一虚拟电极3的整体形状呈折线形，可以使第一虚拟电极3与触控电极之间的金属网格线GL断开后形成的边界较为参差，避免由于长距离直线断线导致第一虚拟电极3与触控电极之间出现明显的线痕的问题，即避免显示装置1000在显示过程中出现消影问题，提高显示装置1000的显示效果。
在一些实施例中，如图24所示，第一触控电极Tx周围设有四个第一虚拟电极3，该四个第一虚拟电极3相对于第一触控电极Tx的中心呈中心对称设置。第二触控电极Rx周围设有四个第一虚拟电极3，该四个第一虚拟电极3相对于第二触控电极Rx的中心呈中心对称设置。
根据前述实施例，可以使得第一触控电极Tx和第二触控电极Rx的形状和面积大致相同，从而使得触控结构10不同位置处的噪声信号大致 相同，则主动笔在触控过程中在触控结构10不同位置处的信噪比大致相同，可以提高主动笔的触控性能，例如，使得主动笔的悬浮高度较为均一。
在一些实施例中，如图25所示，至少一个第一触控通道1包括多个第一子通道1A，多个第一子通道1A沿第二方向Y排列，每个第一子通道1A沿第一方向X延伸，且第一子通道1A包括电连接的多个第一触控电极Tx。例如，参阅图25，一个第一触控通道1包括四个第一子通道1A。
如图25所示，至少一个第二触控通道2包括多个第二子通道2A，多个第二子通道2A沿第一方向X排列，每个第二子通道2A沿第二方向Y延伸，且第二子通道2A包括电连接的多个第二触控电极Tx。例如，参阅图25，一个第二触控通道2包括四个第二子通道2A。
在前述实施方式的基础上，同一第一触控通道1包括的多个第一子通道1A电连接。同一第二触控通道2包括的多个第二子通道2A电连接。
通过在至少一个触控通道(包括第一触控通道1和第二触控通道2)内设置相邻的多个子触控通道(包括第一子通道1A和第二子通道2A)，并设置同一触控通道中的多个子触控通道之间电连接，从而可以在不改变触控结构10中触控单元区域J的面积，从而保障手指触控与显示装置1000的适配度的同时，在触控单元区域J内划分多个与主动笔的笔头尺寸相适配的触控点，极大地提升了主动笔的准确度，兼顾了主动笔在显示装置1000中的触控功能。同时，还有效提升了主动笔在触控过程中的线性度，同时使主动笔在不同位置处的信号量大致均一，悬浮高度大致均一，提升了主动笔的触控体验。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
