具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明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发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，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它实施例，都属于本发明保护的范围。
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发明所属领域内具有一般技能的人士所理解的通常意义。本发明专利申请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。
本公开实施例中附图的尺寸并不是严格按实际比例绘制，触控面板中电容触控电极、电磁触控电极、另一电容触控电极和另一电磁触控电极的个数不限定为图中所示的数量；第一网格线、第二网格线、第三网格线和第四网格线的条数也不限定为图中所示的数量。各个结构的具体的尺寸和数量可根据实际需要进行确定。本公开的实施例中所描述的附图仅是结构示意图。
图1是一种触控面板示意图。如图1所示的触控面板包括基板60和 设置于基板60上的触控电极。触控电极包括多个电容驱动电极70、多个电容感应电极40和多个电磁感应线圈50，每一电容驱动电极70包含多个依次排列的子驱动电极701、702、703和704。在图1所示的触控面板中，每个电容感应电极40的图案呈条状结构，每个电容驱动电极70和每个电磁感应线圈50的图案也均包括条状结构。触控电极的上述条状结构都是横平竖直的，即平行于或垂直于基板60的横向外轮廓或者纵向外轮廓。一方面，这种由较细的条状结构组成的电磁感应线圈50的电阻较大，不利于提高电磁触控的灵敏度；另一方面，当将该触控面板应用于显示面板中时，在显示面板中，像素层的不透明的信号线(例如栅线、数据线等)或黑矩阵(例如液晶显示面板中)通常平行于或垂直于基板的横向外轮廓或者纵向外轮廓，而该触控面板的触控电极的上述条状结构也平行于或垂直于基板60的横向外轮廓或者纵向外轮廓，这样，触控电极的图案容易与像素层的信号线或黑矩阵的图案在视觉上产生摩尔纹效应，这样严重影响了显示面板的显示效果。
本公开至少一实施例提供一种触控面板，该触控面板包括：电容触控电极和电磁触控电极。电容触控电极包括第一网格图案，该第一网格图案包括交叉的多条第一网格线；电磁触控电极与电容触控电极绝缘且包括第二网格图案，该第二网格图案包括交叉的多条第二网格线。例如，本公开的实施例提供的触控面板可以用于显示装置、笔记本电脑的用于控制鼠标的触控板、触控电子锁等具备触控功能的产品中。
例如，该触控面板可以为自电容式触控面板或者自感电磁式触控面板。例如，在本公开一实施例提供的触控面板中，触控面板只包括一个触控电极层，在该一个触控电极层中第一网格图案与第二网格图案同层设置。
示范性地，图2A为本公开一实施例提供的一种触控面板的第一触控电极层的一种平面示意图，图2B为图2A的另一种局部放大示意图。如图2A所示，第一触控电极层10包括同层设置的电容触控电极17和电磁触控电极6。电容触控电极17和电磁触控电极6同层设置有利于触控面板的薄化，简化面板的结构，并且在制作触控面板的过程中，可以通过同一构图工艺形成电容触控电极17和电磁触控电极6的图案，有利于简化制作工序。例如，触控面板包括多个电容触控电极17和多个电磁触控电极6。当然，在本公开的其他实施例中，触控面板也可以包括一个电容触控电极17和一 个电磁触控电极6，本公开的实施例对电容触控电极17的个数和电磁触控电极6的个数不作限定。例如，每个电容触控电极17包括第一网格图案1，该第一网格图案1包括交叉的多条第一网格线101。每个电磁触控电极6与电容触控电极17绝缘，并且，电磁触控电极6包括第二网格图案2，该第二网格图案2包括交叉的多条第二网格线201。本公开的实施例提供的触控面板能够同时实现电容触控和电磁感应触控。与不具有网格图案的条状触控电极相比，一方面，本公开的实施例提供的触控面板的第一网格图案1和第二网格图案2分别增大了电容触控电极17和电磁触控电极6的排布密度，从而能够在保证透过率的同时提高触控面板的电容触控精度和电磁触控精度，即使对于大尺寸触控面板，也能够达到较高的电容触控精度和电磁触控精度；另一方面，在第一网格图案1和第二网格图案2中，至少部分第一网格线101并联设置和/或至少部分第二网格线201并联设置，能够减小电容触控电极17的电阻和电磁触控电极6的电阻，提高触控的灵敏度。
例如，如图2A所示，第一网格图案1与第二网格图案2均沿第一方向延伸，并且，第一网格图案1与第二网格图案2彼此间隔开以使得电容触控电极与电磁触控电极6绝缘。例如，触控面板具有外轮廓9，第一方向与触控面板的外轮廓9横向平行。例如，多条第一网格线101与多条第二网格线201通过多个第一空隙5间隔开以使得第一网格图案1与第二网格图案2彼此间隔开，并且沿第一方向，多个第一空隙5位于与第一方向平行的同一条直线上，以便于图案化。也就是如图2A所示，第一网格图案1与第二网格图案2之间存在由多个第一空隙5组成的整体上呈条形的空隙将第一网格图案1与第二网格图案2彼此间隔开以使得电容触控电极3与电磁触控电极6绝缘。在图2A所示的实施例中，由多个第一空隙5组成的条形空隙呈直线型。当然，在本公开的其他实施例中，由多个第一空隙5组成的条形空隙也可以呈曲线型，例如锯齿形或波浪形等，本公开的实施例对此不作限定。
例如，电磁触控电极6包括第一部分601、第二部分602和连接线603，第一部分601和第二部分602通过连接线603电连接，以形成电磁感应线圈。并且，第一部分601和第二部分602分别包括第二网格图案2并沿第一方向延伸，第一网格图案1位于电磁触控电极6的第一部分601和第二 部分602之间。也就是，在图2A所示的实施例中，电容触控电极17与电磁触控电极6的第一部分601之间以及电容触控电极17与电磁触控电极6的第二部分602之间均存在第一空隙5，以使得电容触控电极17与电磁触控电极6绝缘。
例如，第一网格图案1和第二网格图案2构造为：沿与第一方向相交的第二方向平移第二网格图案2，则第二网格图案2与第一网格图案1的一部分完全重叠。例如，在图2A中，第二方向垂直于第一方向。例如，如图2A和2B所示，第一网格图案1包括多个形状相同且呈周期排列的第一网格单元102；第二网格图案2的第二网格线201的延长线相交可以形成封闭的结构即第二网格单元202，该第二网格单元202的形状相同且呈周期排列。第一网格单元102的平面形状与第二网格单元202的平面形状相同，且第一网格单元102的排布周期与第二网格单元202的排布周期相同。例如，如图2A所示，第一网格单元102和第二网格单元202的平面形状均为菱形。当然，第一网格单元102和第二网格单元202的形状也可以是菱形之外的其他形状。一方面，第一网格图案1和第二网格图案2的上述构造便于通过构图工艺形成第一网格图案1和第二网格图案2；另一方面，在本公开的实施例提供的触控面板用于显示面板中的情况下，第一网格图案1和第二网格图案2的上述构造有利于使显示面板出光均匀，改善或避免因第一触控电极层10透光不均匀而造成的显示缺陷，例如Mura缺陷。
例如，如图2A所示，多条第一网格线101与多条第二网格线201均为直线段，多条第二网格线201的每个的延长线跨过第一空隙5与多条第一网格线101中的一条重合。当然，在本公开的其他实施例提供的触控面板中，多条第一网格线101与多条第二网格线201不限于图2A中的结构。在本公开实施例提供的触控面板用于显示面板中的情况下，这种图案能够使得电容触控电极17和电磁触控电极6的图案整体上排布均匀，有利于使显示面板出光均匀，改善或避免因第一触控电极层10透光不均匀而造成的显示缺陷，例如Mura缺陷。
例如，多个第一空隙5的尺寸大致相等，这样便于通过构图工艺形成第一网格图案1和第二网格图案2，在将该触控面板应用于显示面板中的情况下，也有利于使显示面板的出光均匀。
例如，多个第一空隙5的每个的尺寸L小于10μm。在将该触控面板应用于显示面板中的情况下，如果第一空隙5的尺寸过大，容易出现因第一触控电极层10透光不均匀而造成的显示缺陷，例如Mura缺陷。因此，第一空隙5的每个的尺寸L小于10μm有利于改善这种缺陷。
例如，如图2A所示，多条第一网格线101中的至少部分的延伸方向或多条第二网格线201的至少部分的延伸方向与触控面板的外轮廓9相交且不垂直。在显示面板中，像素层的不透明的信号线(例如栅线、数据线等)或黑矩阵(例如液晶显示面板中)通常平行于或垂直于该外轮廓9，在将该触控面板应用于显示面板中的情况下，有利于改善或防止摩尔纹现象，可以在视觉上获得更好的显示效果。
在本公开的其他实施例中，第二网格图案2可以包括多个形状相同且呈周期排列的第二网格单元202，即第二网格单元202是由第二网格线201而非第二网格线201的延长线相交所形成。例如，图2C为本公开一实施例提供的触控面板的第一触控电极层的另一种平面示意图。图2C所示的触控电极层10与图2A所示的触控电极层10的区别在于，第二网格图案2包括多个形状相同且呈周期排列的第二网格单元202，且第一网格单元102和第二网格单元202的形状均为圆形。图2C中的电容触控电极和电磁触控电极的其他特征均与图2A中的相同。当然，本公开实施例提供的触控面板中，第一网格单元102和第二网格单元202的形状不限于是菱形和圆形，例如，也可以是平行四边形或三角形等其他形状，本公开的实施例对此不作限定。
例如，图2D为图2A的另一种局部放大示意图。图2D所示的第一触控电极层与图2B所示的第一触控电极层的区别在于，第二网格线201的延长线跨过第一空隙5与第一网格线101不重合。图2D中的电容触控电极17和电磁触控电极6的其他特征均与图2B中的相同。
图2E为本公开一实施例提供的触控面板的第一触控电极层的又一种平面示意图，图2F为图2E中的第一触控电极层的局部7的一种放大示意图。如图2E和图2F所示，多条第一网格线101与多条第二网格线201通过彼此分离的多个第一空隙5间隔开以使得第一网格图案1与第二网格图案2彼此间隔开，并且沿第一方向，多个第一空隙5分别位于与第一方向平行的多条直线上。也就是，多个第一空隙5不位于一条直线上，与通过 一整条缝隙间隔开的情形相比(图2A-图2D所示实施例)，这样，电容触控电极17的第一网格线101与电磁触控电极6的第二网格线201在第一空隙5附近的区域彼此交错，使得电容触控电极17和电磁触控电极6能控制或感应的区域范围较大，减小没有触控电极覆盖的空白区，从而提高了触控精度。例如，相邻的两个第一空隙5不位于一条直线上，以使电容触控电极17的第一网格线101与电磁触控电极6的第二网格线201彼此交错，提高了触控精度。
下述的点A1、A2、A3、A4分别为四条示例性的第一网格线101的端点，B1、B2、B3、B4分别为四条示例性的第二网格线201的端点。例如，在图2F中，点A1和点B1之间的第一空隙5与点A3和点B3之间的第一空隙5位于一条沿第一方向的直线上；点A2和点B2之间的第一空隙5与点A4和点B4之间的第一空隙5位于另一条沿第一方向的直线上。例如，在图2E中，所有第一空隙5均是按这种规律排列的，即奇数位置的第一空隙5位于一条沿第一方向的直线上，而偶数位置的第一空隙5位于另一条沿第一方向的直线上。
例如，如图2E和图2F所示，多条第一网格线101与多条第二网格线201均为直线段，多条第二网格线201的每个的延长线跨过多个第一空隙5中的一个并与多条第一网格线101中的一条重合。也就是说，例如在图2F中，点A1与点B1位于同一条直线上，点A2与点B2位于同一条直线上，点A3与点B3位于同一条直线上，点A4和点B4位于同一条直线上……依次类推。这种图案能够使得电容触控电极17和电磁触控电极6的图案整体上比较均匀，有利于使显示面板出光均匀，改善或避免因第一触控电极层10透光不均匀而造成的显示缺陷，例如Mura缺陷。
当然，在本公开的实施例中，每个第一空隙5的位置不限于是图2F所示的情形。例如，图2G为图2E中的第一触控电极层的局部7的另一种放大示意图。图2G所示的第一空隙5与图2F所示的第一空隙5的区别在于，多个第一空隙5的位置是随机的。例如，点A1和点B1点之间的第一空隙5、点A2和点B2点之间的第一空隙5、点A3和点B3点之间的第一空隙5以及点A4和点B4点之间的第一空隙5位于四条不同的沿第一方向的直线上。与图2F所示的结构相比，图2G所示的结构更加有利于使得电容触控电极17和电磁触控电极6能控制或感应的区域范围较大，减小没有 触控电极覆盖的空白区，从而提高触控精度。
例如，本公开一实施例提供的触控面板只包括一个触控电极层，例如包括一个图2A-图2G所示的任意一种第一触控电极层，这种情况下，该触控面板为自电容式和自感电磁式触控面板。图2A-图2G同时是本公开一实施例提供的触控面板的平面示意图，图2H为这种情况下的触控面板的剖面示意图。如图2H所示，触控面板还可以包括衬底基板12。例如，第一触控电极层10设置于衬底基板12上，即电容触控电极17和电磁触控电极6设置于衬底基板12上。触控面板还可以包括覆盖第一触控电极层10的第一保护层14，以防止电容触控电极17和电磁触控电极6受到损害(例如磨损、腐蚀等)。在图2A-图2H所示的自电容式和自感电磁式触控面板中，电容触控电极17和电磁触控电极6均为同层设置，同层设置的优点请参考之前的描述。当然，在本公开的其他实施例提供的自电容式和自感电磁式触控面板中，电容触控电极17和电磁触控电极6也可以设置在不同的层。
例如，在本公开的实施例提供的触控面板中，电容触控电极17的第一网格线101的材料和电磁触控电极6的第二网格线201的材料可以为金属材料，例如Al、Cu、Ag、Mo等金属或合金。例如，第一保护层14的材料可以为绝缘材料，以防止外界电信号干扰电容触控电极17和电磁触控电极6的工作。例如，根据需要，第一保护层14可以为透明材料，例如当触控面板用于显示面板中时。例如其可以为透明的无机材料(氧化硅、氮化硅或氮氧化硅等)，也可以为有机绝缘材料，例如树脂材料。例如透明树脂，例如聚丙烯、聚酰亚胺等。当然，电容触控电极17的第一网格线101的材料、电磁触控电极6的第二网格线201的材料和第一保护层的材料不限于上述列举种类。
例如，触控面板还包括驱动装置、触控检测装置和控制器。触控检测装置与电容触控电极和电磁触控电极电连接，可用于检测触摸点的位置，触控检测装置可以与驱动装置电连接或独立设置。控制器与触控检测装置信号连接(例如电连接)，控制器可用于接收来自触控检测装置的检测结果。
当上述自电容式和自感电磁式触控面板执行电容式触控功能时，驱动装置配置为发出电容触控扫描信号，驱动装置发出的电容触控扫描信号传输至电容触控电极。例如，当手指触摸到触控面板时，手指的电容将会叠 加到触控电极的电容上，使触控电极的电容变化，触控检测装置能够检测出触摸前后电容的变化，并对接收到的信息进行分析、计算，将其转换为接触点的位置坐标，然后将其发送至控制器。例如该驱动装置包括电容触控驱动电路，发出的电容触控扫描信号为驱动电流信号。例如该触控检测装置包括电容触控检测电路。
当上述自电容式和自感电磁式触控面板执行电磁感应触控功能时，驱动装置配置为发出电磁触控扫描信号，驱动装置发出的电磁触控扫描信号传输至电磁触控电极，电磁触控电极在该电磁触控扫描信号的作用下发出第一电磁信号。例如，当电磁笔触摸到电容屏时，电磁笔内的震荡电路可以感应位于触摸位置的电磁触控电极所发出的第一电磁信号并谐振产生第二电磁信号，该电磁触控电极接收第二电磁信号并产生电磁感应信号，触控检测装置能够检测到该电磁感应信号，从而对检测到的信息进行分析、计算，将其转换为接触点的位置坐标，然后将其发送至控制器。例如，该驱动装置包括电磁感应触控驱动电路，发出的电磁触控扫描信号为激磁电流。例如，该触控检测装置包括电磁感应触控检测电路。
当将该触控面板用于触控显示装置中时，该控制器可以是触控显示装置的处理器(例如CPU等)，该控制器同时还可以控制驱动装置进行相应的操作。
本公开另一实施例提供的触控面板也可以为互电容式和互感电磁式触控面板，除了上述第一触控电极层，该触控面板还包括第二触控电极层。示范性地，图3A为本公开一实施例提供的触控面板的第二触控电极层的一种平面示意图。例如，如图3A所示，本公开另一实施例提供的触控面板还包括另一电容触控电极18和另一电磁触控电极8。例如，另一电容触控电极18和另一电磁触控电极8同层设置，均位于第二触控电极层11。此时，该触控面板为互电容式和互感电磁式触控面板。另一电容触控电极18包括第三网格图案3，该第三网格图案3包括交叉的多条第三网格线301；另一电磁触控电极8包括第四网格图案4，该第四网格图案4包括交叉的多条第四网格线401，另一电容触控电极18和另一电磁触控电极8相互绝缘，且另一电容触控电极18和另一电磁触控电极8均与电容触控电极和电磁触控电极6绝缘。
例如，第三网格图案3与第四网格图案4同层设置，第三网格图案3 与第四网格图案4均沿与第一方向相交的第二方向延伸并且彼此间隔开。例如，第二方向与第一方向垂直，以便于触控面板工作时计算触摸位置的坐标。例如，多条第三网格线301与多条第四网格线401通过多个第二空隙501间隔开以使得第三网格图案3与第四网格图案4彼此间隔开，并且沿第一方向，多个第二空隙501位于与第二方向平行的同一条直线上，以便于图案化。也就是如图3A所示，第三网格图案301与第四网格线401之间存在由多个第二空隙501组成的整体上呈条形的空隙将第三网格图案3与第四网格图案4彼此间隔开以使得另一电容触控电极18与另一电磁触控电极8绝缘。在图3A所示的实施例中，由多个第二空隙501组成的条形空隙呈直线型。当然，在本公开的其他实施例中，由多个第二空隙501组成的条形空隙也可以呈曲线型，例如锯齿形或波浪形等，本公开实施例对此不作限定。第二空隙501的其他特征均与第一空隙5的特征相同，可以参考之前的描述，在此不再赘述。
例如，另一电磁触控电极8包括第一部分801、第二部分802和连接线803，另一电磁触控电极8的第一部分801和另一电磁触控电极8的第二部分802通过另一电磁触控电极8的连接线803电连接，以形成另一电磁感应线圈。并且，另一电磁触控电极8的第一部分801和另一电磁触控电极8的第二部分802分别包括第四网格图案4并沿如图3A所示的第二方向延伸，第三网格图案3位于另一电磁触控电极8的第一部分801和另一电磁触控电极8的第二部分802之间。即，在图3A所示的实施例中，另一电容触控电极18与另一电磁触控电极8的第一部分801之间以及另一电容触控电极18与另一电磁触控电极8的第二部分802之间均存在第二空隙501，使得另一电容触控电极18与另一电磁触控电极8绝缘。
如图3A所示，第三网格图案3和第二网格图案4的构造方式与图2A所示的第一网格图案1和第二网格图案2的构造方式相同，其可以参考之前关于图2A所示的第三网格图案3和第二网格图案4的构造方式的描述，在此不再赘述。如此，当将第一触控电极层20和第二触控电极层以堆叠的方式设置于触控面板中时，第三网格线301和第四网格线401与第一网格线101和第二网格线201部分重叠。
图3B为本公开一实施例提供的触控面板的第二触控电极层的另一种平面示意图，图3C为图3B中的第二触控电极层的局部701的一种放大示 意图。图3B和图3C所示的第三网格图案3和第四网格图案4的构造方式与图2E和图2F所示的第一网格图案1和第二网格图案2的构造方式相同。其与图3A所示的第三网格图案3和第四网格图案4的区别在于，多条第三网格线301与多条第四网格线401通过彼此分离的多个第二空隙501间隔开以使得第三网格图案3与第四网格图案4彼此间隔开，并且沿第二方向，多个第二空隙501分别位于与第二方向平行的多条直线上。也就是，多个第二空隙501不位于一条直线上，与通过一整条缝隙间隔开的情形相比(图3A所示实施例)，另一电容触控电极18的第三网格图案3与另一电磁触控电极8的第四网格图案4在第二空隙501附近的区域彼此交错，使得另一电容触控电极18和另一电磁触控电极8能控制或感应的区域范围较大，减小没有触控电极覆盖的空白区，从而提高触控精度。
例如，图3D为图3B中的第二触控电极层的局部701的另一种局部放大示意图。图3D所示的第三网格图案3和第四网格图案4的构造方式与图2G所示的第一网格图案1和第二网格图案2的构造方式相同。图3D所示的第二空隙501与图3C所示的第二空隙501的区别在于，多个第二空隙501所在的沿第二方向的直线的位置是随机的。与图3C所示的结构相比，图3D所示的结构更加有利于使得电容触控电极和电磁触控电极能控制或感应的区域范围较大，减小没有触控电极覆盖的空白区，从而提高触控精度。
示范性地，图4A为本公开一实施例提供的一种触控面板的平面示意图，图4B为图4A中触控面板100的局部1001的放大示意图。例如，如图4A和图4B所示，在触控面板100中，第一网格图案1和第二网格图案2所在的层(例如上述第一触控电极层)与第三网格图案3和第四网格图案4所在的层(例如第二触控电极层)以堆叠的方式设置。并且，在与第一网格图案1和第二网格图案2所在的层以及第三网格图案3和第四网格图案4所在的层垂直的方向上，第三网格线301和第四网格线401与第一网格线101和第二网格线201部分重叠。例如，在本公开实施例中，可以使尽可能多的第三网格线301和第四网格线401与第一网格线101和第二网格线201重叠，如此，在将该触控面板用于显示面板中的情况下，有利于增大触控面板的透光区的面积，提高光的透过率。
需要说明的是，另一电容触控电极和另一电磁触控电极的其他特征， 例如材料、网格图案的最小单元的形状、间隙尺寸等，均与电容触控电极和电磁触控电极的相同，请参考之前的描述。
触控面板100还包括驱动装置、触控检测装置和控制器。触控检测装置与电容触控电极和电磁触控电极电连接，可用于检测触摸点的位置，触控检测装置可以与驱动装置电连接或独立设置。例如，如图4A所示，触控检测装置(图中未示出)通过端口CX1、CX2、CX3……分别与第一触控电极层的多个电容触控电极电连接，并通过端口CY1、CY2、CY3……分别与第二触控电极层的多个另一电容触控电极电连接；触控检测装置通过端口MX1a/MX1b、MX2a/MX2b、MX3a/MX3b……分别与第一触控电极层的多个电磁触控电极电连接，并通过端口MY1a/MY1b、MY2a/MY2b、MY3a/MY3b……分别与第二触控电极层的多个另一电磁触控电极电连接。控制器(图中未示出)与触控检测装置信号连接(例如电连接)，控制器可用于接收来自触控检测装置的检测结果。
当本公开实施例提供的互电容式和互感电磁式触控面板执行电容式触控功能时，驱动装置配置为发出电容触控扫描信号，驱动装置发出的电容触控扫描信号通过端口CX1、CX2、CX3……传输至各个电容触控电极，并通过端口CY1、CY2、CY3……传输至各个另一电容触控电极。多个电容触控电极和多个另一电容触控电极在交叠处可形成互电容。当有手指触摸触控面板100时，影响了触摸点附近电容的耦合，从而改变了触摸点附近电容的电容量。触控检测装置能够检测出触摸前后电容的变化，并对接收到的信息进行分析、计算，将其转换为接触点的位置坐标，然后将其发送至控制器。例如，通过来自沿第一方向延伸的电容触控电极的信号确定触摸位置在第一方向上的坐标，通过来自沿第二方向延伸的另一电容触控电极的信号确定触摸位置在第二方向上的坐标，从而确定发生触摸的位置。例如该驱动装置包括电容触控驱动电路，发出的电容触控扫描信号为驱动电流信号。例如该触控检测装置包括电容触控检测电路。
当本公开实施例提供的互电容式和互感电磁式触控面板执行电磁感应触控功能时，驱动装置配置为发出电磁触控扫描信号，驱动装置发出的电磁触控扫描信号通过端口MX1a、MX2a、MX3a……传输至第一触控电极层的各个电磁触控电极，电磁触控电极在该电磁触控扫描信号的作用下发出驱动电磁信号；同时，驱动装置发出的电磁触控扫描信号通过端口 MY1a、MY2a、MY3a……传输至第二触控电极层的各个另一电磁触控电极，另一电磁触控电极在该电磁触控扫描信号的作用下发出另一驱动电磁信号。驱动电磁信号和另一驱动电磁信号会互相叠加而形成第一电磁信号。例如，当电磁笔触摸到电容屏时，电磁笔内的震荡电路可以感应位于触摸位置的第一电磁信号并谐振产生第二电磁信号，位于触摸位置的电磁触控电极和另一电磁触控电极接收第二电磁信号并分别产生电磁感应信号，触控检测装置能够检测到来自位于触摸位置的自电磁触控电极和另一电磁触控电极电磁感应信号，从而对检测到的信息进行分析、计算，将其转换为接触点的位置坐标，然后将其发送至控制器。例如，通过来自沿第一方向延伸的电磁触控电极的电磁感应信号确定触摸位置在第一方向上的坐标，通过来自沿第二方向延伸的另一电磁触控电极的电磁感应信号确定触摸位置在第二方向上的坐标，从而确定发生触摸的位置。例如该驱动装置包括电磁感应触控驱动电路，发出的电磁触控扫描信号为激磁电流。例如该触控检测装置包括电磁感应触控检测电路。
当将该触控面板用于触控显示装置中时，该控制器可以是触控显示装置的处理器(例如CPU等)，该控制器同时还可以控制驱动装置进行相应的操作。

图5B为沿图4A中的I-I’线的另一种剖面示意图。在图5B所示的触控面板中，第一触控电极层10设置在衬底基板12的第一侧，第二触控电极层11设置在衬底基板12的第二侧，第二侧与第一侧相反。也就是，第一网格图案和第二网格图案设置在衬底基板12的第一侧，第三网格图案和第四网格图案设置在衬底基板12的第二侧。例如，触控面板还可以包括覆 盖第二触控电极层11的第二保护层15，以防止另一电容触控电极18和另一电磁触控电极8受到损害(例如磨损、腐蚀等)。第二保护层15的材料可以与第一保护层的材料相同，请参考之前的描述。
图5C为沿图4A中的I-I’线的又一种剖面示意图。在图5C所示的实施例中，触控面板包括相对设置的第一衬底基板1201和第二衬底基板1202，第一触控电极层10设置在第一衬底基板1201上，第二触控电极层11设置在第二衬底基板1202上。也就是，第一网格图案1和第二网格图案2设置在第一衬底基板1201上，第三网格图案3和第四网格图案4设置在第二衬底基板1202上。例如，触控面板还包括粘结第一衬底基板1201和第二衬底基板1202的粘结层16。例如，粘结层16可以是粘结胶。图5C所示的触控面板的其他特征均与图5B所示的相同，在此不再赘述。
需要说明的是，根据实际需要，图5A-图5C所示的不同的层之间还可以有其他的层的存在。例如，在将本公开实施例提供的触控面板用于显示装置中的情况下，可以在该不同的层之间设置显示层(例如液晶层、有机发光显示器件层、显示驱动电路层、基板等等)，以根据需要形成on-cell(外挂型)或in-cell(内嵌型)或OGS型等不同类型的触控显示面板。
本公开至少一实施例还提供一种触控显示面板，该触控显示面板包括本公开实施例提供的任意一种触控面板。本公开实施例提供的触控显示面板能够同时实现电容触控和电磁感应触控，并且，能够在保证较高的透过率的同时，具有较高电容触控精度和电磁触控精度以及较高的触控的灵敏度。
示范性地，图6为本公开一实施例提供的一种触控显示面板示意图。如图6所示，触控显示面板200包括本公开实施例提供的任意一种触控面板100。可以根据需要形成on-cell(外挂型)或in-cell(内嵌型)或OGS型等不同类型的触控显示面板。例如，该触控显示面板200可以是液晶显示面板、有机发光二极管(OLED)显示面板等。
例如，图7为本公开一实施例提供的一触控种显示面板的平面示意图，图8A为沿图7中的H-H’线的一种剖面示意图，图8B为沿图7中的H-H’线的另一种剖面示意图。
如图7和图8A所示，本公开实施例提供的触控显示面板还包括显示层20，显示层20包括多条相互交叉的信号线204以及多个位于信号线204 之间的显示单元203。第一网格线101的至少部分或第二网格线201的至少部分在显示层20上的正投影与信号线204相交且不垂直，以达到改善或避免显示过程中的摩尔纹的效果。例如，如图7所示，信号线204与衬底基板12的横向外轮廓或者纵向外轮廓垂直或平行，而触控面板的多条第一网格线101的延伸方向或多条第二网格线201的延伸方向均与衬底基板12的横向外轮廓或者纵向外轮廓相交且不垂直，则穿过信号线204形成的网格图案的光和穿过第一网格图案1和第二网格图案2的光的相位差别较大，这两部分光互相干涉后不容易出现明显的摩尔纹现象，从而本公开实施例提供的触控显示面板能够在视觉上达到更好的显示效果。在触控显示面板包括黑矩阵的情况下，例如在液晶显示面板中，第一网格线101的至少部分或第二网格线201的至少部分在显示层20上的正投影也可以与黑矩阵相交且不垂直，同样可以达到上述改善或避免显示过程中的摩尔纹的效果。
例如，信号线可以包括各种类型的线，例如栅线、数据线、电源线、公共电极线、复位线等等。
