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。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的实施例，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他实施例，都属于本公开保护的范围。
除非另外定义，本公开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。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“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。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”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。
本公开中的附图并不是严格按实际比例绘制，触控基板中的第一触控电极、第二触控电极、第一触控子电极、第二触控子电极、第一连接电极、第二连接电极、连接子电极以及导电网格等的个数也不是限定为图中所示的数量，各个结构的具体尺寸和数量可以根据实际需要进行确定。本公开中所描述的附图仅是结构示意图。
有机发光二极管(OLED)显示面板具有自发光、对比度高、能耗低、视角广、响应速度快、可用于挠曲性面板、使用温度范围广、制造简单等特点，具有广阔的发展前景。为了满足用户多样化的使用需求，在显示面板中集成多种功能，如触控功能、指纹识别功能等具有重要的意义。例如，在OLED显示面板中形成外挂式(on-cell)触控结构是一种实现方式，该方式通过将触控结构形成于OLED显示面板的封装膜之上，从而使OLED显示面板实现触控功能。
例如，以互容式触控结构为例，互容式触控结构包括多个触控电极，该多个触控电极包括沿不同方向延伸的触控驱动电极Tx和触控感测电极Rx，触控驱动电极Tx和触控感测电极Rx在彼此交叉处形成用于触控感测的互电容。触控驱动电极Tx用于输入激励信号(例如触控驱动信号)，触控感测电极Rx用于输出触控感测信号。通过向例如纵向延伸的触控驱动电极输入激励信号，从例如横向延伸的触控感测电极接收触控感测信号，这样可以得到反映横向和纵向电极耦合点(例如交叉点)的电容值大小的检测信号。当手指触摸到触摸屏(例如盖板玻璃)时，影响了触摸点附近的触控驱动电极Tx和触控感测电极Rx之间的耦合，从而改变了这两个电极之间在交叉点处形成的互电容的电容量，导致输出的触控感测信号出现变化。根据触控感测信号的数据变化量，可以计算出触摸 点的相应坐标。
图1为一种互容式触控结构的工作原理示意图。如图1所示，在触控驱动电路TOUC的驱动下，触控驱动电极Tx被施加触控驱动信号，并由此产生电场线E，该电场线E被触控感测电极Rx接收形成参考电容。当手指触摸到触摸屏SCRN上时，由于人体是导体，触控驱动电极Tx产生的一部分电场线E被引导至手指形成手指电容(Finger Capacitance)，减少了触控感测电极Rx所接收的电场线E，因此触控驱动电极Tx和触控感测电极Rx之间的电容值减小。触控驱动电路TOUC通过触控感测电极Rx来获得上述电容值的大小，并将获得的电容值与参考电容相比较，从而获得电容值变化量；根据该电容值变化量的数据以及结合各个触控电容的位置坐标，可以计算出触摸点的相应坐标。
本公开至少一实施例提供一种触控基板，该触控基板包括衬底基板以及位于衬底基板上的多个第一触控电极和多个第二触控电极；多个第一触控电极沿第一方向排列，各第一触控电极沿不同于第一方向的第二方向延伸，多个第二触控电极沿第二方向排列，各第二触控电极沿第一方向延伸；各第一触控电极与各第二触控电极之间彼此间隔且绝缘；在垂直于衬底基板的方向上，各第一触控电极分别与多个第二触控电极之间彼此交叠，各第二触控电极分别与多个第一触控电极之间彼此交叠，以使多个第一触控电极和多个第二触控电极之间形成多个交叠区域和多个非交叠区域；第一触控电极和第二触控电极分别包括由多个导电网格形成的网格状结构；导电网格包括沿第一方向延伸的第一边缘；在交叠区域中，第二触控电极的导电网格中包括至少一条第一边缘，且第一触控电极的导电网格中不设置与第二触控电极的导电网格中包括的该至少一条第一边缘在垂直于衬底基板的方向上重叠的第一边缘。
在本公开上述实施例提供的触控基板中，在交叠区域中，使第一触控电极的导电网格中不设置与第二触控电极的导电网格中包括的第一边缘重叠的第一边缘，也即，使第一触控电极的位于交叠区域中的导电网格不包括第一边缘，或者在第一触控电极的位于交叠区域中的导电网格包括第一边缘的情况下，使第一触控电极的导电网格中的该第一边缘不与第二触控电极的导电网格中的第一边缘之间产生交叠。由此，可以减少第一触控电极与第二触控电极之间在交叠区域中的交叠面积，进而有利于减小第一触控电极与第二触控电极之间在交叠区域中能够形成的电容的大小，缩短所需的充电时间。由此，在第一触控电极与第二触控电极之间在交叠区域中形成的电容的数值发生变化时，可以缩短获取该电容的数值的变化量所需的时间，从而提升触控基板的触控灵敏度和准确度。
下面，将参考附图详细地说明本公开的实施例。应当注意的是，不同的附图中相同的附图标记将用于指代已描述的相同的元件。
图2为本公开一些实施例提供的一种触控基板的平面结构示意图，图3为本公开一些实施例提供的一种触控基板的截面结构示意图，例如图3为沿图2中所示的A-A’线的截面图。
如图2和图3所示，该触控基板10包括衬底基板11以及位于衬底基板11上的多个 第一触控电极100和多个第二触控电极200。多个第一触控电极100沿第一方向R1排列，各第一触控电极100沿不同于第一方向R1的第二方向R2延伸。多个第二触控电极200沿第二方向R2排列，各第二触控电极200沿第一方向R1延伸。
例如，第一方向R1与第二方向R2之间的夹角可以设置在70°到90°之间，且包括70°和90°，例如，第一方向R1与第二方向R2之间的夹角可以为70°、75°、80°、85°或90°等，夹角的具体数值可以根据实际情况设定，本公开的实施例对此不作具体限制。
例如，在本公开实施例提供的触控基板10中，第一方向R1可以设置为垂直于第二方向R2。当本公开实施例提供的触控基板10应用于例如显示面板或显示装置时，第一方向R1可以为显示面板或显示装置中的子像素阵列的列方向，第二方向R2可以为显示面板或显示装置中的子像素阵列的行方向；或者，第一方向R1可以为显示面板或显示装置中的子像素阵列的行方向，第二方向R2可以为显示面板或显示装置中的子像素阵列的列方向，本公开的实施例对此不作限制。
如图2和图3所示，在垂直于衬底基板11的方向R3上，各第一触控电极100分别与多个第二触控电极200之间彼此交叠，各第二触控电极200分别与多个第一触控电极100之间彼此交叠，以使多个第一触控电极100和多个第二触控电极200之间形成多个交叠区域OVR和多个非交叠区域。
各第一触控电极100与各第二触控电极200之间彼此间隔且绝缘，也即，每个第一触控电极100均与其他第一触控电极100以及多个第二触控电极200之间彼此间隔且绝缘，每个第二触控电极200均与其他第二触控电极200以及多个第一触控电极100之间彼此间隔且绝缘。
下面本公开的实施例以图2和图3中所示的第一触控电极100包括第一触控子电极101和第一连接电极102，第二触控电极200包括第二触控子电极201和第二连接电极202的情形为例，对本公开一些实施例提供的触控基板进行具体说明，但是需要注意的是，本公开的实施例包括但并不仅限于此。
在本公开的一些实施例中，如图2和图3所示，第一触控电极100包括多个第一触控子电极101和多个第一连接电极102，多个第一触控子电极101沿第二方向R2排列，第一连接电极102位于在第二方向R2上相邻的两个第一触控子电极101之间，以使相邻的两个第一触控子电极101通过该第一连接电极102彼此电连接。第二触控电极200包括多个第二触控子电极201和多个第二连接电极202，多个第二触控子电极201沿第一方向R1排列，第二连接电极202位于在第一方向R1上相邻的两个第二触控子电极201之间，以使相邻的两个第二触控子电极201通过第二连接电极202彼此电连接。
需要说明的是，图2中所示的第一触控电极100中包括的第一触控子电极101和第一连接电极102的数量以及第二触控电极200中包括的第二触控子电极201和第二连接电极202的数量均仅是示例性说明，本公开的实施例对此均不作具体限制。
需要说明的是，图2中所示的第一触控电极100中的第一触控子电极101以及第二触控电极200中的第二触控子电极201的主体轮廓均为菱形；而在本公开的其他一些实 施例中，第一触控子电极101和第二触控子电极201也可以采用例如三角形、长方形、六边形、八边形、条形等其他规则形状或不规则形状等，本公开的实施例对此不作限制。例如，第一触控子电极101和第二触控子电极201的主体轮廓可以彼此相同，也可以彼此不同。
图4A和图4B为图2中所示的区域RG1的一种示例的局部放大示意图。图5为本公开一些实施例提供的一种触控基板的平面结构的局部放大示意图，例如图5示出了图2中所示的区域RG1中的部分平面结构的放大示意图。图6A为本公开一些实施例提供的一种第一连接电极的示意图，例如图6A为图4A和图4B中所示的第一连接电极102的示意图，图6A示出了位于图3所示的第一导电层310中的第一连接电极102的平面结构。图6B为本公开一些实施例提供的一种触控基板的第二导电层中的部分结构的平面示意图，例如图6B示出了位于图3所示的第二导电层320中的第一触控子电极101、第二触控子电极201以及第二连接电极202的平面结构，图6B为图4A和图4B中所示的第一触控子电极101、第二触控子电极201以及第二连接电极202的示意图。
需要说明的是，图4A至图6B中为了清楚地表示第一触控子电极101、第一连接电极102、第二触控子电极201和第二连接电极202，用虚线框大致示出了对应的部分。但是，需要注意的是，该虚线框仅用于表示第一触控子电极101、第一连接电极102、第二触控子电极201和第二连接电极202的大致位置，并不是用于表示对各电极的具体划分边缘或边界线的限定。
如图2至图6B所示，第一触控电极100和第二触控电极200分别包括由多个导电网格400形成的网格状结构。例如，在第一触控电极100的网格状结构中，多个导电网格400的主体轮廓、所围成的区域的面积等可以彼此相同，也可以彼此不同；在第二触控电极200的网格状结构中，多个导电网格400的主体轮廓、所围成的区域的面积等可以彼此相同，也可以彼此不同，本公开的实施例对此均不作具体限制。
如图2至图6B所示，在交叠区域OVR中，第一触控电极100的导电网格400中沿第一方向R1延伸的第一边缘EDG1(例如第一边缘EDG11)与第二触控电极200的导电网格400中沿第一方向R1延伸的第一边缘EDG1(例如第一边缘EDG12)在第二方向R2上彼此间隔设置，以使第一触控电极100的导电网格400中包括的第一边缘EDG11与第二触控电极200的导电网格400中包括的第一边缘EDG12之间在垂直于衬底基板11的方向R3上不发生交叠。例如，在交叠区域OVR中，第一触控电极100的导电网格400中沿第一方向R1延伸的第一边缘EDG11在衬底基板11上的正投影与第二触控电极200的导电网格400中沿第一方向R1延伸的第一边缘EDG12在衬底基板11上的正投影之间没有交叠，且彼此之间在第二方向R2上具有一定间距(该间距大于0)。
由此，可以减少第一触控电极100与第二触控电极200之间在交叠区域OVR中的交叠面积，从而有利于减小第一触控电极100与第二触控电极200之间在交叠区域OVR中能够形成的电容的大小，缩短所需的充电时间。进而，在第一触控电极100与第二触控电极200之间在交叠区域OVR中形成的电容的数值发生变化时，可以缩短获取该电容的 数值的变化量所需的时间，从而提升触控基板10的触控灵敏度和准确度。
需要说明的是，在本公开的上述实施例中，第一触控电极100的位于交叠区域OVR中的导电网格400包括第一边缘EDG11；或者，在本公开的其他一些实施例中，第一触控电极100的位于交叠区域OVR中的导电网格400也可以不包括第一边缘EDG11，由此避免与第二触控电极200的导电网格400中包括的第一边缘EDG12之间发生交叠。
例如，如图2至图6B所示，导电网格400包括沿第一方向R1延伸的第一边缘EDG1(例如第一边缘EDG11和EDG12)和沿第二方向R2延伸的第二边缘EDG2(例如第二边缘EDG21和EDG22)，第一边缘EDG1和第二边缘EDG2交替连接以构成导电网格400。
例如，第一方向R1可以垂直于第二方向R2，以构成图4A至图6B中所示的主体轮廓为方形的导电网格400，也即该导电网格400为方形导电网格。或者，在本公开的其他一些实施例中，第一触控电极100和第二触控电极200中的导电网格400也可以采用例如三角形、菱形、六边形、八边形、条形等其他规则形状或不规则形状等，本公开的实施例对此不作限制。
例如，如图4A至图6B所示，在交叠区域OVR中，第一触控电极100的导电网格400中沿第二方向R2延伸的第二边缘EDG2(也即，第二边缘EDG21)与第二触控电极200的导电网格400中沿第二方向R2延伸的第二边缘EDG2(也即，第二边缘EDG22)在第一方向R1上彼此间隔设置，以使第一触控电极100的导电网格400中包括的第二边缘EDG21与第二触控电极200的导电网格400中包括的第二边缘EDG22之间在垂直于衬底基板11的方向R3上不发生交叠。例如，在交叠区域OVR中，第一触控电极100的导电网格400中沿第二方向R2延伸的第二边缘EDG21在衬底基板11上的正投影与第二触控电极200的导电网格400中沿第二方向R2延伸的第二边缘EDG22在衬底基板11上的正投影之间没有交叠，且彼此之间在第一方向R1上具有一定间距(该间距大于0)。进而，可以进一步减少第一触控电极100与第二触控电极200之间在交叠区域OVR中的交叠面积。
需要说明的是，在本公开的上述实施例中，第二触控电极200的位于交叠区域OVR中的导电网格400包括第二边缘EDG22；或者，在本公开的其他一些实施例中，第二触控电极200的位于交叠区域OVR中的导电网格400也可以不包括第二边缘EDG22，由此避免与第一触控电极100的导电网格400中包括的第二边缘EDG21之间发生交叠。
例如，如图4A至图6B所示，在交叠区域OVR中，第一触控电极100的导电网格400中的各第一边缘EDG11在第二方向R2上位于第二触控电极200的导电网格400中在第二方向R2上相邻的两条第一边缘EDG12之间。例如，在交叠区域OVR中，在第二方向R2上，第一触控电极100的导电网格400中的第一边缘EDG11与第二触控电极200的导电网格400中的第一边缘EDG12交替设置，也即，在第二方向R2上，第一触控电极100的导电网格400中的第一边缘EDG11在衬底基板11上的正投影与第二触控电极200的导电网格400中的第一边缘EDG12在衬底基板11上的正投影之间彼此交替 排列。由此，既可以减少第一触控电极100与第二触控电极200之间在交叠区域OVR中的交叠面积，有利于减小第一触控电极100与第二触控电极200之间在交叠区域OVR中能够形成的电容的大小，进而缩短所需的充电时间，又可以提升第一触控电极100以及第二触控电极200上的信号传输的稳定性和可靠性，从而实现对触控基板10的整体性能的优化。
例如，以图2至图6B所示的实施例为例，第一连接电极102与第二连接电极202至少部分位于交叠区域OVR中，例如第一连接电极102与第二连接电极202部分位于交叠区域OVR中且部分位于非交叠区域中。
第一连接电极102与第二连接电极202分别位于相对于衬底基板11的不同导电层中，第一连接电极102与第二连接电极202之间在垂直于衬底基板11的方向R3上彼此部分交叠，以使得第一触控电极100的第一连接电102与第二触控电极200的第二连接电极202之间在交叠区域OVR中能够形成电容。进而，通过获取第一连接电极102与第二连接电极202之间在交叠区域OVR中形成的电容的数值的变化，实现触控基板10的触控功能。
例如，结合图2至图6B所示，触控基板10包括位于衬底基板11上的第一导电层310、绝缘层330和第二导电层320，绝缘层330位于第一导电层310和第二导电层320之间，第一导电层310和第二导电层320通过绝缘层330在垂直于衬底基板11的方向R3上彼此间隔且绝缘。第一触控子电极101位于第二导电层320，第一连接电极102位于第一导电层310，第一触控子电极101通过至少贯穿绝缘层330的过孔结构HS与第一连接电极102连接。
例如，第二触控子电极201和第二连接电极202均位于第二导电层320。第二连接电极202在相邻的两个第二触控子电极201之间连续设置。换句话说，各第二连接电极202在相邻的两个第二触控子电极201之间保持连续且不间断，例如第二连接电极202可以与相邻的两个第二触控子电极201一体设置，例如可以采用相同的制备工艺通过同一材料层(例如第二导电层320)形成。
例如，在图4A至图6B所示的实施例中，第一连接电极102包括沿第一方向R1并排设置的两个第一连接子电极1021，该两个第一连接子电极1021位于在第二方向R2上相邻的两个第一触控子电极101之间。每个第一连接子电极1021的两端分别通过过孔结构HS与该两个第一触控子电极101连接，以实现该两个第一触控子电极101之间的信号传输。
需要说明的是，本公开的实施例对用于连接第一触控子电极101与对应的连接子电极1021的过孔结构HS中所包括的过孔的数量、位置、排布方式等均不作具体限制。例如，在图4A和图4B所示的实施例中，用于连接第一触控子电极101与对应的第一连接子电极1021的过孔结构HS中包括4个过孔，该4个过孔分别对应于一个导电网格400的四个顶点。又例如，在后文图11和图12A至图12B以及图13A和图13B所示的实施例中，用于连接第一触控子电极101与对应的第一连接子电极1021的过孔结构HS中的 4个过孔也可以分别设置在对应于两个相邻的导电网格400构成的“8字”型结构的四个顶点处。例如，在图12A和图12B所示的示例中，4个过孔分别设置在该两个相邻的导电网格400中彼此不共用的四个顶点处，以适当增加过孔结构HS附近的各子像素500与对应的导电网格400的各顶点及边缘之间的间距(具体可参见后文中关于图12A和图12B所示的示例的相应描述)，从而既可以保证各子像素500的正常显示，又可以减弱或避免相邻的两个子像素500之间可能发生色偏的风险。
或者，在本公开的其他一些实施例中，过孔结构HS中所包括的过孔也可以采用其他适合的设置方式等，过孔结构HS中所包括的过孔的数量也可以为1个、2个、3个、5个、6个或更多个等，本公开的实施例对此不作具体限制。
例如，在图2至图6B所示的实施例中，该第一连接电极102包括沿第二方向R2延伸的两个第一连接子电极1021；而在本公开的其他一些实施例中，该第一连接电极102也可以仅包括沿第二方向R2延伸的一个第一连接子电极1021，或者也可以包括沿第二方向R2延伸的3个、4个、5个或更多个第一连接子电极1021，该多个第一连接子电极1021沿第一方向R1依次排列。本公开的实施例对于第一连接电极102中包括的第一连接子电极1021的数量不作具体限制。
例如，在图2至图6B所示的实施例中，各第一连接子电极1021在交叠区域OVR中均包括在第二方向R2上依次设置的两个第一边缘EDG11；而在本公开的其他一些实施例中，各第一连接子电极1021在交叠区域OVR中包括的第一边缘EDG11的数量也可以彼此不同，并且一个第一连接子电极1021在交叠区域OVR中包括的第一边缘EDG11的数量也可以为1个、3个、4个或更多个等，或者第一连接子电极1021在交叠区域OVR中也可以不设置第一边缘EDG11，本公开的实施例对此均不作具体限制。
例如，参考图2至图6B所示，两个第一连接子电极1021沿第一方向R1依次排列，且该两个第一连接子电极1021的延伸方向基本平行，例如，该两个第一连接子电极1021均分别整体上大致沿第二方向R2延伸。
例如，每个第一连接子电极1021由多个导电网格400构成，并且在交叠区域OVR中，第一连接子电极1021中在第二方向R2上相邻的导电网格400的中心大致位于沿第二方向R2延伸的同一直线上，由此使第一连接子电极1021在相邻的两个第一触控子电极101之间形成由多个导电网格400构成的直梯状导电结构。例如，构成第一连接子电极1021的多个导电网格400在第一方向R1上的宽度可以彼此相同，从而改善形成的直梯状导电结构上的信号传输的一致性和稳定性。
例如，在图2至图6B所示的实施例中，第二连接电极202包括沿第二方向R2并排设置的三个第二连接子电极2021，例如每个第二连接子电极2021由在第一方向R1上相邻的多个导电网格400中的第一边缘EDG12依次连接形成，从而形成整体上大致沿第一方向R1延伸的直线型导电结构，进而实现在第一方向R1上相邻的两个第二触控子电极201之间的信号传输。
需要说明的是，在图2至图6B所示的实施例中，该第二连接电极202包括沿第一方 向R1延伸的三个第二连接子电极2021；而在本公开的其他一些实施例中，该第二连接电极202中也可以仅包括沿第一方向R1延伸的一个第二连接子电极2021，或者也可以包括沿第一方向R1延伸的2个、4个、5个或更多个第二连接子电极2021，该多个第二连接子电极2021在第二方向R2上依次排列。本公开的实施例对于第二连接电极202中包括的第二连接子电极2021的数量不作具体限制。
例如，在图2至图6B所示的实施例中，两个第一连接子电极1021之间在第一方向R1上具有间距，第二连接电极202在两个第一连接子电极1021之间还通过多个第二边缘EDG22将多个第二连接子电极2021之间彼此电连接，并且在该多个第二边缘EDG22之间还相应设置了多个第一边缘EDG12。由此，在交叠区域OVR中，使第二连接电极202在两个第一连接子电极1021之间还可以形成用于连接多个第二连接子电极2021的多个导电网格400，从而进一步提升第二连接电极202上的信号传输的稳定性和可靠性。
需要说明的是，在本公开的其他一些实施例中，两个第一连接子电极1021之间在第一方向R1上的间距也可以缩小，第二连接电极202中不设置用于连接相邻的两个第二连接子电极2021的第二边缘EDG22；或者，两个第一连接子电极1021之间在第一方向R1上的间距也可以进一步增大，以使第二连接电极202中可以设置更多个用于连接相邻的两个第二连接子电极2021的第二边缘EDG22，本公开的实施例对此不作具体限制。
例如，结合图5所示的区域RG1中的部分平面结构的局部放大示意图为例，第一连接电极102中的两个第一连接子电极1021位于在第二方向R2上相邻的两个第一触控子电极101之间，且均分别与该两个第一触控子电极101连接，以实现该两个第一触控子电极101之间的信号传输。例如，该两个第一连接子电极1021基本平行设置且分别大致沿第二方向R2延伸，由此可以在相邻的两个第一触控子电极101之间形成近似直梯状的连接结构。
例如，该两个第一连接子电极1021的整体延伸方向可以完全平行(例如，100％平行)且为第二方向R2，由此以形成直梯状的连接结构；或者，该两个第一连接子电极1021的整体延伸方向之间也可以形成一个大于0°的夹角，例如该夹角的取值范围可以为大于0°且小于等于20°，例如具体可以为2°、5°、8°、10°、12°、15°、18°等，本公开的实施例对此不作具体限制。
例如，第一触控子电极101以及第一连接电极102中由第一边缘EDG11构成的沿第一方向R1延伸的各边缘线以及由第二边缘EDG21构成的沿第二方向R2延伸的各边缘线的形状可以为直线形状、折线形状、弧线形状、曲线形状等，或者也可以为上述形状的组合或其他适合的形状；第二触控子电极201以及第二连接电极202中由第一边缘EDG12构成的沿第一方向R1延伸的各边缘线以及由第二边缘EDG22构成的沿第二方向R2延伸的各边缘线的形状可以为直线形状、折线形状、弧线形状、曲线形状等，或者也可以为上述形状的组合或其他适合的形状，本公开的实施例对此不作具体限制。
例如，在本公开的一些实施例中，如图5所示，第一触控电极100以及第二触控电极200的网格状结构中可以通过在导电网格400的第一边缘EDG1或第二边缘EDG2上 设置切口的方式，在第一触控电极100以及第二触控电极200的网格状结构中形成一个或多个浮置电极部分301。该浮置电极部分301可以配置为处于悬置或浮置状态，例如，该浮置电极部分301不与任何信号源或导电结构(例如第一触控电极100或第二触控电极200)连接。由此，有利于减弱或避免第一触控电极100与第二触控电极200之间、以及第一触控电极100或第二触控电极200与触控基板中的其他走线、器件或结构等之间可能产生的相互干扰，进而提升触控基板的稳定性和可靠性。
例如，在图2至图6B所示的实施例中，第二导电层320位于第一导电层310的远离衬底基板11的一侧。或者，在本公开的其他一些实施例中，也可以是第一导电层310位于第二导电层320的远离衬底基板11的一侧。
例如，在图2至图6B所示的实施例中，第二导电层320可以是相对于第一导电层310更加靠近用户的一侧的导电层，进而在第一触控子电极101、第二触控子电极201以及第二连接电极202均位于第二导电层320的情况下，可以提高第一触控电极100和第二触控电极200上所接收的来自用户一侧的信号的准确性和灵敏性，进而提高触控基板10的触控灵敏度和准确度。
在本公开的一些实施例中，如图4A至图6B所示，第一触控电极100中的导电网格400在交叠区域OVR中所围成的区域的面积大于或等于在非交叠区域中所围成的区域的面积。例如，第一连接电极102中的导电网格400在交叠区域OVR中所围成的方形区域的面积可以大于第一连接电极102或第一触控子电极101中的导电网格400在非交叠区域中所围成的方形区域的面积。
例如，第一连接电极102以及第一触控子电极101中的导电网格400在非交叠区域中所围成的方形区域的主体轮廓、面积等彼此基本相同。以第一连接电极102以及第一触控子电极101中的导电网格400在非交叠区域中所围成的正方形区域的面积为一个单位面积为例，第一连接电极102中的导电网格400在交叠区域OVR中所围成的长方形区域的面积为大约2个单位面积。
在本公开的一些实施例中，如图4A至图6B所示，第二触控电极200中的导电网格400在交叠区域OVR中所围成的区域的面积大于或等于在非交叠区域中所围成的区域的面积。例如，第二连接电极202中的导电网格400在交叠区域OVR中所围成的方形区域的面积大于或等于第二连接电极202或第二触控子电极201中的导电网格400在非交叠区域中所围成的方形区域的面积。
例如，第二连接电极202以及第二触控子电极201中的导电网格400在非交叠区域中所围成的方形区域的主体轮廓、面积等彼此基本相同。以第二连接电极202以及第二触控子电极201中的导电网格400在非交叠区域中所围成的正方形区域的面积为一个单位面积为例，第二连接电极202中的导电网格400在交叠区域OVR中所围成的方形区域的面积为大约1个单位面积、2个单位面积或6个单位面积。
由此，通过使第一触控电极100中的导电网格400在交叠区域OVR中所围成的区域的面积大于或等于在非交叠区域中所围成的区域的面积，且使第二触控电极200中的导 电网格400在交叠区域OVR中所围成的区域的面积大于或等于在非交叠区域中所围成的区域的面积，可以减少第一触控电极100和第二触控电极200的网格状结构中用于传输电信号的导电网格400的各边缘(例如第一边缘EDG1和第二边缘EDG2)在交叠区域OVR中所占据的面积。由此，可以进一步减少第一触控电极100与第二触控电极200之间在交叠区域OVR中的交叠面积，缩短所需的充电时间。
在本公开的一些实施例中，如图4A至图6B所示，第一触控电极100中的导电网格400在交叠区域OVR中的排布密度小于或等于在非交叠区域中的排布密度。例如，在平行于衬底基板11的平面内，对于面积相同且分别位于交叠区域OVR和非交叠区域中的两个不同子区域，例如位于交叠区域OVR中的第一子区域和位于非交叠区域中的第二子区域，第一触控电极100的网格状结构在第一子区域中所包含的导电网格400的数量小于或等于在第二子区域中所包含的导电网格400的数量。
在本公开的一些实施例中，如图4A至图6B所示，第二触控电极200中的导电网格400在交叠区域OVR中的排布密度小于或等于在非交叠区域中的排布密度。也即，在平行于衬底基板11的平面内，对于面积相同且分别位于交叠区域OVR和非交叠区域中的两个不同子区域，例如位于交叠区域OVR中的第三子区域和位于非交叠区域中的第四子区域，第二触控电极200的网格状结构在第三子区域中所包含的导电网格400的数量小于或等于在第四子区域中所包含的导电网格400的数量。
由此，可以减少第一触控电极100和第二触控电极200的网格状结构中用于传输电信号的导电网格400的各边缘(例如第一边缘EDG1和第二边缘EDG2)在交叠区域OVR中所占据的面积，进而进一步减少第一触控电极100与第二触控电极200之间在交叠区域OVR中的交叠面积，缩短所需的充电时间。
在本公开的一些实施例中，该导电网格400为金属网格。例如，第一触控电极100和第二触控电极200的网格状结构中的金属网格的材料可以包括铝、钼、铜、银等金属材料或者这些金属材料的合金材料，例如为银钯铜合金材料等，本公开的实施例对此不作具体限制。
需要说明的是，图2至图6B中所示的网格状结构的图案(例如轮廓、包括的导电网格的个数、尺寸、形状等)只是示例性说明，本公开的实施例对于网格状结构中形成的导电网格400的个数以及例如形状、轮廓、大小等具体图案特征等均不作具体限制。例如，网格状结构中的导电网格400可以均为多边形，例如均为四边形，而在本公开的其他一些实施例中，导电网格400的形状也可以为其他多边形，例如三角形、五边形、六边形等，具体可根据实际需要进行设计，本公开的实施例对导电网格400的具体形状、尺寸等不作限定。
图7为本公开一些实施例提供的一种触控基板用于与显示器件层叠设置的平面示意图，例如图7示出了图4A和图4B中的第一触控电极100以及第二触控电极200与显示器件中的子像素500之间在平行于衬底基板11的平面内的位置对应关系。图8A为图7中所示的区域RG2的一种示例的局部放大示意图，图8B为图7中所示的区域RG3的一 种示例的局部放大示意图。
需要说明的是，除显示器件中的子像素500以外，图7至图8B所示的实施例中的触控基板10的结构、设置方式、功能等均与图2至图6B所示的实施例中的基本相同或相似，具体内容可参考关于图2至图6B所示的实施例中的相应描述，重复之处在此不再赘述。
如图7至图8B所示，该触控基板10配置为与显示器件层叠设置，该显示器件包括呈阵列排布的多个像素单元，每个像素单元包括多个子像素500(例如子像素501～503)。各子像素500分别对应于一个导电网格400，且各子像素500在衬底基板11上的正投影位于对应的导电网格400在衬底基板11上的正投影所围成的区域内。
需要说明的是，在本公开的其他一些实施例中，也可以是一个导电网格400对应于多个子像素500，且多个子像素500在衬底基板11上的正投影均位于对应的导电网格400在衬底基板11上的正投影所围成的区域内。例如，一个像素单元中的子像素501～503均对应于同一个导电网格400。本公开的实施例对于一个导电网格400所对应的子像素500的具体数量不作限制。
例如，在图7至图8B所示的实施例中，多个子像素501～503的尺寸彼此不同，也即，该多个子像素501～503在衬底基板11上的正投影所围成的区域的面积彼此不同。
例如，以图7至图8B所示的实施例中具有不同尺寸的三个子像素501～503为例，其中尺寸相对最小的子像素501与触控电极中用于设置过孔结构HS的导电网格400对应。在本公开的其他一些实施例中，触控电极中用于设置过孔结构HS的导电网格400也可以与尺寸相对较大的子像素502或子像素503对应。这样，可以有助于增加触控电极中用于设置过孔结构HS的导电网格400的各顶点之间的相对距离，从而既有利于触控基板的制备工艺的优化，又可以减弱相邻的过孔结构HS之间可能产生的信号干扰。
例如，导电网格400的边缘呈折线形状延伸。例如，该导电网格400的沿第一方向R1延伸的第一边缘EDG1和沿第二方向R2延伸的第二边缘EDG2均分别呈折线形状延伸。例如，导电网格400的边缘的弯折角度可以为10°～20°，进一步可以为12°～18°，例如可以为12°、14°、15°、16°或18°等。
由此，可以降低或避免第一触控电极100和第二触控电极200的网格状结构与子像素阵列之间可能产生的干涉，进而有利于减弱或避免出现电极可视化现象，从而实现对触控基板10的光学性能的优化。同时，还可以减弱或避免显示画面中可能出现的例如点状、线状或块状的暗态刻蚀纹或摩尔(mura)纹等现象，从而减弱或避免显示画面中可能存在的可视性显示不良，改善画面的显示效果。
例如，导电网格400的第一边缘EDG1和第二边缘EDG2也可以分别呈曲线形状、弧线形状或其他适合的形状延伸，本公开的实施例对此不作具体限制。
本公开实施例提供的触控基板中，通过将导电网格400的边缘设计为呈折线形状、弧线形状或曲线形状(例如波浪形的曲线形状)延伸，导电网格400的边缘上的不同位置处可以具有不同的曲率方向。由此，不仅可以减弱导电网格400的各边缘可能产生的 反射现象，有效降低宏观下触控电极的可视化，例如降低了触控电极的边缘处的可视化现象，同时还可以减弱导电网格400的各边缘之间可能产生的干涉，有效降低微观下一个方向上或一个区域内的亮度差异，从而提升应用该触控基板的显示产品的显示品质。
例如，以导电网格400的第一边缘EDG1和第二边缘EDG2采用弧线形状为例，在第一边缘EDG1与第二边缘EDG2的连接处，弧形的第一边缘EDG1的切线与第一方向R1的夹角可以约为12°至18°，例如可以为14°左右，弧形的第二边缘EDG2的切线与第二方向R2的夹角可以约为12°至18°，例如可以为14°左右。
本公开实施例提供的触控基板中，通过将第一边缘EDG1与第一方向R1之间的夹角以及第二边缘EDG2与第二方向R2之间的夹角设置为12°至18°左右，可以最大限度地提高消影效果，降低触控电极的边缘可视化现象。
需要说明的是，在本公开的其他一些实施例中，对于一个导电网格400，也可以是两个第一边缘EDG1中的一个为折线或曲线形状，另一个为直线形状；也可以是两个第二边缘EDG2中的一个为折线或曲线形状，另一个为直线形状，本公开的实施例对此不作具体限制。
例如，多个子像素500可以分别配置为提供不同颜色的光，例如多个子像素501～503可以分别配置为提供不同颜色的光，例如分别配置为提供红光、蓝光、绿光等，本公开的实施例对此不作限制。
例如，以提供同一颜色的光的多个子像素501为例，如图7和图8A所示，该多个子像素501包括沿第二方向R2排列的第一子像素5011和第二子像素5012。例如，在沿第二方向R2排列的多个子像素501中，第一子像素5011和第二子像素5012在第二方向R2上彼此相邻，也即，在第二方向R2上，第一子像素5011和第二子像素5012之间不设置其他子像素501。与第一子像素5011对应的导电网格401的第二边缘EDG2的弯折方向，以及与第二子像素5012对应的导电网格402的第二边缘EDG2的弯折方向在第一方向R1上彼此相对设置。例如，导电网格401的第二边缘EDG2均向右侧弯折(也即，向右侧突出)，例如第二边缘EDG2呈近似V形的折线形状，V型的开口方向向左；导电网格402的第二边缘EDG2均向左侧弯折(也即，向左侧突出)，例如第二边缘EDG2呈近似V形的折线形状，V型的开口方向向右。进而，使导电网格401的第二边缘EDG2的弯折方向与导电网格402的第二边缘EDG2的弯折方向在第一方向R1上彼此相反，从而减弱或避免在第二方向R2上相邻的两个子像素501之间可能发生色偏的风险。
例如，如图7和图8A所示，该多个子像素501还包括第三子像素5013，第三子像素5013与第一子像素5011沿第一方向R1排列。例如，在沿第一方向R1排列的多个子像素501中，第一子像素5011和第三子像素5013在第一方向R1上彼此相邻，也即，在第一方向R1上，第一子像素5011和第三子像素5013之间不设置其他子像素501。与第一子像素5011对应的导电网格401的第一边缘EDG1的弯折方向，以及与第三子像素5013对应的导电网格403的第一边缘EDG1的弯折方向在第二方向R2上彼此相对设置。例如，导电网格401的第一边缘EDG1均向下方弯折(也即，向下侧突出)，例如第一 边缘EDG1呈近似V形的折线形状，V型的开口方向向上；导电网格403的第一边缘EDG1均向上方弯折(也即，向上侧突出)，例如第一边缘EDG1呈近似V形的折线形状，V型的开口方向向下。进而，使导电网格401的第一边缘EDG1的弯折方向与导电网格403的第一边缘EDG1的弯折方向在第二方向R2上彼此相反，从而减弱或避免在第一方向R1上相邻的两个子像素501之间可能发生色偏的风险。
需要说明的是，上述“弯折方向”是指导电网格400的边缘的整体轮廓，例如上述“呈近似V形”是指导电网格400的边缘形状的整体轮廓呈近似V形，构成该V形的两条彼此相接的线段可以为呈直线型延伸的直线段，也可以为呈例如折线型、锯齿型或其他适合的形状延伸的线段。换句话说，本公开的实施例对构成导电网格400的边缘的两条线段的具体形状不作限制，例如两条线段的边缘可以包括直线型、折线型、锯齿形、三角形、波浪形或其他适合的形状等，本公开的实施例对此不作具体限制。
例如，各子像素500与对应的导电网格400的各边缘或各顶点之间的距离均在预设范围内。例如，该预设范围可以为8μm～15μm。例如，进一步而言，各子像素500与对应的导电网格400的各边缘之间的距离范围可以为8μm～10μm，例如为9μm。
例如，各子像素500与对应的导电网格400的各边缘之间的最小距离可以设置为8μm～10μm，例如为9μm，从而可以有效降低触控电极中的网格图案对出光性能可能造成的不良影响。
例如，以图7所示的区域RG3中的子像素501为例，如图8B所示，该子像素501与在第二方向R2上彼此相对的两条第一边缘EDG1之间的间距以及与在第一方向R1上彼此相对的两条第二边缘EDG2之间的间距均基本保持一致，该子像素501与导电网格400的各顶点(例如顶点CR1～CR4)之间的间距均基本保持一致。
例如，可以通过适当调整与该子像素501对应的导电网格400的第一边缘EDG1以及第二边缘EDG2的延伸长度以及延伸方向、角度等，以使该子像素501与对应的导电网格400的各边缘之间的间距均保持在预设范围内，例如均基本近似于同一数值；或者，也可以通过适当调整导电网格400中的各顶点CR1～CR4之间的相对位置，以使该子像素501与对应的导电网格400的各顶点之间的间距均保持在预设范围内，例如均基本近似于同一数值。
例如，如图8B所示，该导电网格400中，位于左下方的顶点CR1相比于位于左上方的顶点CR2更加偏向右侧，位于右下方的顶点CR4相比于位于右上方的顶点CR3更加偏向左侧，以使得该子像素501与导电网格400的各顶点CR1～CR4之间的间距均基本保持一致。进而，可以降低或避免第一触控电极100和第二触控电极200的网格状结构中的导电网格400与子像素500之间可能产生的干涉，实现对触控基板10的光学性能的进一步优化。
例如，在任意一个导电网格400中，导电网格400的至少一个边缘(例如第一边缘EDG1和/或第二边缘EDG2)上可以设置有切口，该切口断开环形的网格图案。例如，该切口可以理解为切割第一边缘EDG1或第二边缘EDG2的假想线。
图9为本公开一些实施例提供的一种网格状结构中的切口的设置方式的示意图。例如图9示出了图4A和图4B中的第一触控电极100以及第二触控电极200的网格状结构中的切口的设置方式。需要说明的是，除导电网格400中的切口410以外，图9所示的实施例中的触控基板10的结构、设置方式、功能等均与图2至图6B所示的实施例中的基本相同或相似，具体内容可参考关于图2至图6B所示的实施例中的相应描述，重复之处在此不再赘述。
在本公开的一些实施例中，如图9所示，该导电网格400包括闭合网格420，以及还包括在导电网格400的边缘上设置一个或多个切口410的非闭合网格430。第一触控电极100中，位于非交叠区域中的导电网格400中的切口410的数量大于或等于位于交叠区域OVR中的导电网格400中的切口410的数量；第二触控电极200中，位于非交叠区域中的导电网格400中的切口410的数量大于或等于位于交叠区域OVR中的导电网格400中的切口410的数量。进而，可以降低第一触控电极100和第二触控电极200在交叠区域OVR中的信号传输负载，改善第一触控电极100和第二触控电极200的信号传输效果。
例如，第一触控电极100中的位于交叠区域OVR中的导电网格400均为闭合网格420，第二触控电极200中的位于交叠区域OVR中的导电网格400均为闭合网格420。也即，在交叠区域OVR中，导电网格400的各边缘上不设置切口，以使交叠区域OVR中的导电网格400均为闭合网格420。由此，可以减少第一触控电极100和第二触控电极200在交叠区域OVR中的信号传输负载，改善第一连接电极102在两个相邻的第一触控子电极101之间的信号连通效果以及第二连接电极202在两个相邻的第二触控子电极201之间的信号连通效果，从而提升第一触控电极100和第二触控电极200在交叠区域OVR中的信号传输的稳定性和可靠性。
需要说明的是，图9中所示的闭合的导电网格420以及非闭合的导电网格430的个数、形状、尺寸等均仅是示例性说明，本公开的实施例对此不作具体限制。
例如，在本公开的上述实施例中，第一触控电极100中用于设置过孔结构HS的导电网格400均为闭合网格420，也即，第一触控子电极101以及第一连接电极102中用于设置过孔结构HS以实现彼此电连接的导电网格400均为闭合网格420。由此，有利于改善第一连接电极102与对应的第一触控子电极101之间的信号连通效果，从而提升第一触控电极100中的信号传输的稳定性和可靠性。
需要说明的是，在本公开的其他一些实施例中，对于第一连接电极102中包括多个第一连接子电极1021的情况，也可以将其中部分第一连接子电极1021中用于设置过孔结构HS的导电网格400设置为非闭合的导电网格430，本公开的实施例对此不作具体限制。
图10为图2中所示的区域RG1的另一种示例的局部放大示意图。需要说明的是，除连接子电极1021之间在第一方向R1上的间距以外，图10所示的实施例中的触控基板10的结构、设置方式、功能等均与图2至图6B所示的实施例中的基本相同或相似，具体内容可参考关于图2至图6B所示的实施例中的相应描述，重复之处在此不再赘述。
例如，如图10所示，根据实际不同需求，相比于图4A和图4B所示的实施例，第一连接电极102中相邻的两个连接子电极1021之间在第一方向R1上的间距可以相对减小，第二连接电极202在第一方向R1上的尺寸也可以相应地减小。进而，可以进一步减小第一触控电极100和第二触控电极200之间在交叠区域OVR中的交叠面积，缩短所需的充电时间。
图11为本公开一些实施例提供的另一种第一连接电极的示意图，图12A为本公开一些实施例提供的另一种触控基板用于与显示器件层叠设置的平面示意图，图12B为图12A中所示的区域RG4的一种示例的局部放大示意图。例如，图11为图12A中所示的第一连接电极102的示意图。需要说明的是，除连接子电极1021中包括的导电网格400的数量以及用于与第一触控子电极101连接的过孔结构HS的设置位置以外，图11至图12B所示的实施例中的触控基板10的结构、设置方式、功能等均与图2至图6B所示的实施例以及图7至图8B所示的实施例中的基本相同或相似，具体内容可参考关于图2至图6B所示的实施例以及图7至图8B所示的实施例中的相应描述，重复之处在此不再赘述。
例如，如图11、图12A以及图12B所示，相比于图4A至图6B所示的实施例，第一连接电极102中的连接子电极1021在交叠区域OVR中包括更多的导电网格400，且该连接子电极1021在第二方向R2上的延伸长度也相应地相对增加。进而，可以降低第一触控电极100在交叠区域OVR中的信号传输负载，提升交叠区域OVR中的信号传输的稳定性和可靠性。
需要说明的是，本公开的实施例对第一连接电极102的连接子电极1021中包括的导电网格400的具体数量不作限制。例如，连接子电极1021中包括的导电网格400的数量可以为1个、2个、3个、4个、5个或更多个等。
例如，如图11至图12B所示，相比于图8A和图8B中所示的示例，过孔结构HS通过对应的第一连接子电极1021中的多个导电网格400与对应的第一连接子电极1021连接。例如，过孔结构HS中的4个过孔分别位于第一连接子电极1021中在第二方向R2上相邻设置的两个导电网格400中彼此不共用的四个顶点处，例如在位于上方的导电网格400的顶点CR2及CR3处以及位于下方的导电网格400的顶点CR1及CR4处。
进而，在图12A和图12B所示的示例中，以子像素501为例，相比于图8A和图8B所示的示例，由于该子像素501对应的导电网格400中只需在该导电网格400的顶点CR2和CR3处设置过孔，因此该子像素501与对应的导电网格400中的各边缘EDG1、EDG2以及各顶点CR1～CR4之间的间距可以被适当增大；以子像素502为例，相比于图8A和图8B所示的示例，由于该子像素502对应的导电网格400中只需在该导电网格400的顶点CR1和CR4处设置过孔，因此该子像素502与对应的导电网格400中的各边缘EDG1、EDG2以及各顶点CR1～CR4之间的间距可以被适当增大；以子像素503为例，相比于图8A和图8B所示的示例，由于在该子像素503对应的导电网格400中，只需在该导电网格400的顶点处设置相应过孔而在该导电网格400的例如边缘EDG2的中间位置不设置过孔，因此该子像素503与对应的导电网格400中的各边缘EDG1、EDG2以及各顶点 CR1～CR4之间的间距也可以被适当增大。由此，既可以保证各子像素500的正常显示，又可以减弱或避免相邻的两个子像素500之间可能发生色偏的风险。
图13A为图2中所示的区域RG1的再一种示例的局部放大示意图，图13B为本公开一些实施例提供的再一种第一连接电极的示意图，例如图13B为图13A中所示的第一连接电极102的示意图。
例如，如图13A和图13B所示，在交叠区域OVR中，第一触控电极100的导电网格400中沿第二方向R2延伸的边缘EDG2与第二触控电极200的导电网格400中沿第二方向R2延伸的边缘EDG2在第一方向R1上彼此间隔且交替设置。并且，第一触控电极100的网格状结构在该交叠区域OVR中不设置沿第一方向R1延伸的边缘EDG1。由此，可以进一步减少第一触控电极100与第二触控电极200之间在交叠区域OVR中的交叠面积，缩短所需的充电时间。
需要说明的是，关于图13A和图13B所示的实施例中的触控基板10的结构、设置方式、功能等具体内容可参考关于图2至图6B所示的实施例中的相应描述，重复之处在此不再赘述。
在本公开的一些实施例中，绝缘层330的材料可以为无机绝缘材料，例如该无机绝缘材料为透明材料。例如该无机绝缘材料为氧化硅、氮化硅、氮氧化硅等硅的氧化物、硅的氮化物或硅的氮氧化物，或者氧化铝、氮化钛等包括金属氮氧化物绝缘材料。
例如，该绝缘层330的材料也可以是有机绝缘材料，以获得良好的耐弯折性。例如，该有机绝缘材料为透明材料。例如，该有机绝缘材料为OCA光学胶。例如，该有机绝缘材料可以包括聚酰亚胺(PI)、丙烯酸酯、环氧树脂、聚甲基丙烯酸甲酯(PMMA)等。
需要说明的是，在其他一些实施例中，也可以是在第一方向R1上相邻的两个第二触控子电极201之间通过桥接结构连接，而在第二方向R2上相邻的两个第一触控子电极101之间通过与第一触控子电极101位于同一层且一体成型设置的第一连接电极102连接，也即，上述在第二方向R2上相邻的两个第一触控子电极101之间采用的电连接方式与在第一方向R1上相邻的两个第二触控子电极201之间采用的电连接方式可以彼此互换。
在本公开的一些实施例中，第一触控电极100和第二触控电极200之间彼此绝缘，可以是第一触控电极100为触控驱动电极，第二触控电极200为触控感测电极；或者，也可以是第一触控电极100为触控感测电极，第二触控电极200为触控驱动电极，本公开的实施例对此不作限制。
例如，当上述触控基板应用于例如显示面板或显示装置时，每个第一触控电极100和每个第二触控电极200可以分别与一条信号线电连接，并通过该信号线连接至触控控制器或触控集成电路。以第一触控电极100为触控驱动电极，第二触控电极200为触控感测电极为例，该触控集成电路例如可以为触控芯片，用于为向第一触控电极100提供触控驱动信号并从第二触控电极200接收触控感测信号以及对接收的触控感测信号进行处理，例如将处理的数据/信号提供给系统控制器，以实现触控感测功能。例如，信号线 与该触控集成电路连接的一端可以均布置在显示面板的触控区的同一侧，以便于与该触控集成电路的连接；或者，也可以在一个第一触控电极100的两端分别设置一条信号线，在工作时该触控集成电路同时通过两条信号线向一个第一触控电极100双向输入触控驱动信号(双边驱动)，使得第一触控电极100上信号加载的速度提高，从而可以提高检测速度。
本公开至少一实施例还提供一种显示面板，该显示面板包括显示器件以及本公开任一实施例所述的触控基板。在该显示面板中，显示器件和触控基板层叠设置。
图14为本公开一些实施例提供的一种显示面板的示意框图。例如，如图14所示，该显示面板60包括显示器件601和触控基板602。例如，显示器件601和触控基板602可以层叠设置，例如该触控基板602可以为本公开任一实施例所述的触控基板，例如上述实施例中的触控基板10。
例如，在本公开的一些实施例中，该显示面板60还可以包括位于显示器件601与触控基板602之间的封装层，从而避免显示器件601与触控基板602中的例如功能性结构或膜层材料之间可能产生的相互干扰。

如图15所示，该触控基板602位于显示器件601的显示侧，例如为在使用过程中更接近用户的一侧。
例如，本实施例以显示面板为OLED显示面板为例进行介绍，例如该OLED显示面板可以为On-cell或In-cell触控显示面板。当然，在其他一些实施例中，该显示面板也可以为液晶显示面板，本公开的实施例对采用本公开实施例提供的触控基板的显示面板的具体类型不作限定。
例如，该显示器件601包括阵列排布的多个子像素。例如，该显示面板60为OLED显示面板，该多个子像素可以包括绿色子像素、红色子像素或蓝色子像素等。每个子像素包括发光元件23以及驱动该发光元件23发光的像素驱动电路。本公开的实施例对于像素驱动电路的类型以及具体组成不作限制，例如，该像素驱动电路可以是电流驱动型也可以是电压驱动型，可以是2T1C(即两个晶体管和一个电容，该两个晶体管包括驱动晶体管以及数据写入晶体管)驱动电路，可以是在2T1C的基础上进一步包括补偿电路(补偿晶体管)、发光控制电路(发光控制晶体管)、复位电路(复位晶体管)等的驱动电路。
为了清楚起见，图15示出了该像素驱动电路中与该发光元件23直接电连接的第一晶体管24，该第一晶体管24可以是驱动晶体管，配置为工作在饱和状态下并控制驱动发光元件23发光的电流的大小。例如，该第一晶体管24也可以为发光控制晶体管，用于控制驱动发光元件23发光的电流是否流过。本公开的实施例对第一晶体管的具体类型不作限制。

第一晶体管24包括栅极341、栅极绝缘层342、有源层343、第一极344和第二极345，该第二极345与发光元件23的第一电极231电连接。本公开的实施例对于第一晶体管24的类型、材料、结构等均不作限制，例如其可以为顶栅型、底栅型等。例如，第一晶体管24的有源层343可以为非晶硅、多晶硅(低温多晶硅与高温多晶硅)、氧化物半导体(例如，氧化铟镓锡(IGZO))等。例如，第一晶体管24可以为N型晶体管或P型晶体管。
本公开的实施例中采用的晶体管(例如第一晶体管24)均可以为薄膜晶体管或场效应晶体管或其他特性相同的开关器件，本公开的实施例中均以薄膜晶体管为例进行说明。这里采用的晶体管的源极、漏极在结构上可以是对称的，所以其源极、漏极在结构上可以是没有区别的。在本公开的实施例中，为了区分晶体管除栅极之外的两极，直接描述了其中一极为第一极，另一极为第二极。
如图15示，该显示器件601还包括像素界定层322，该像素界定层322设置于该发光元件23的第一电极231上，其中形成多个开口321，分别暴露多个子像素的第一电极231，从而定义出每个子像素的像素开口区，子像素的发光层形成在该像素开口区，而第二电极232形成为公共电极(即为多个子像素共享)。
如图15示，该显示器件601还包括位于该发光元件23与触控基板602之间的封装层33，该封装层33配置为对发光元件23进行密封，以防止外界的湿气和氧气向该发光元件23及驱动电路渗透而造成对例如发光元件23等器件的损坏。例如，封装层33可以是单层结构或多层结构，例如包括有机薄膜、无机薄膜或者包括有机薄膜及无机薄膜交替层叠的多层结构。

(3)在不冲突的情况下，本公开的实施例及实施例中的特征可以相互组合以得到新的实施例。
以上，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，本公开的保护范围应以权利要求的保护范围为准。
