 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例1
本申请实施例提供了一种触控显示面板100，请参阅图2，触控显示面板100包括显示区101与非显示区102，以及沿第一方向排列的第1个至第n个触控电极单元10、沿第一方向排列的2n条触控引线20以及沿第一方向排列的多个焊盘30。其中，触控电极单元10位于显示区101内，焊盘30位于非显示区102内。
其中，n为大于1的自然数，在本实施例中，n为3；第一方向为横向方向，即由左至右方向或是由右至左方向。
每个触控电极单元10包括两个以上的触控驱动电极110和两个以上的触控感应电极120，触控驱动电极110沿第二方向排布于第一直线上，触控感应电极120沿第二方向排布于第二直线上，第二方向垂直第一方向，第二直线平行于第一直线。
任一触控驱动电极110与至少一触控感应电极120相对设置，触控驱动电极110与触控感应电极120用于耦合形成多个互电容感测节点，通过感测互电容感测节点的电容变化来确定用户的触摸位置信息。
其中，第二方向为纵向方向，即由上至下方向或是由下至上方向。
在第一方向，触控驱动电极110与触控感应电极120相间隔设置；对于第一个触控电极单元10和第二个触控单元：第一个触控电极单元10中的触控感应电极120与第二个触控电极单元10中的触控驱动电极110相邻设置，第一个触控电极单元10中的触控感应电极120位于第一个触控电极单元10中的触控驱动电极110和第二个触控电极单元10中的触控驱动电极110之间。
其中，触控驱动电极110与触控感应电极120设置在同一层，触控显示面板100为单层互容式触控显示面板100。可选的，触控驱动电极110与触控感应电极120的制作材料为无机非金属材料或者金属材料。其中，无机非金属材料可以为透明材料，比如铟锡氧化物。金属材料包括：钛、铝、钼、纳米银中任意一种或多种。
在一种实施例中，触控驱动电极110与触控感应电极120均为网格状触控电极，其中，在垂直于显示面板方向上一个网格状触控电极与多个子像素交叠，网格状触控电极包括多个开口，开口暴露子像素的出光区域，能够减少触控驱动电极110和触控感应电极120对光线的遮挡，显示时减少光线穿过触控电极层(触控驱动电极110、触控感应电极120以及触控引线20所在的膜层)造成的光损失，保证显示面板的亮度。尤其对于金属材料制作的驱动电极和感应电极来说，网格状触控电极的设计能够有效降低光线穿透金属层造成的光损失，在保证触控性能的同时也保证显示面板的亮度。
触控引线20包括触控驱动引线210和触控感应引线220，触控驱动引线210用于连接触控驱动电极110至焊盘30，触控感应引线220用于连接触控感应电极120至焊盘30。触控驱动引线210的首端连接对应的触控驱动电极110，末端延伸到非显示区102内与对应的焊盘30连接；触控感应引线220的首端连接对应的触控感应电极120，末端延伸到非显示区102内与对应的焊盘30连接。
触控驱动引线210和触控感应引线220的材料可以为ITO、银浆或是MOALMO等阻低阻抗导电材料，以降低线间距，提高走线精度，从而降低引线布局空间。
与焊盘30相连接的触控驱动引线210与触控感应引线220均不交叉，以避免采用跨桥结构，降低工艺难度，可以通过设置各个焊盘30在第一方向上的排序实现。
触控显示面板100还包括电路板（图未示）和芯片40，电路板和芯片40也位于非显示区102内，焊盘30通过电路板与芯片40电连接，用于传输触控电极单元10与芯片40之间的信号，实现触摸感测。
触控显示面板100包括至少一特定区域103，特定区域103位于显示区内，触控电极单元10在一特定区域103内的部分包括触控驱动电极110和触控感应电极120组。其中，触控驱动电极110包括一驱动电极本体111及突出于驱动电极本体111的第一齿状部112，任意两个相邻的第一齿状部112之间形成第一间隙113；触控感应电极组，包括两个感应电极本体121及突出于每一感应电极本体121的第二齿状部122，任意两个相邻的第二齿状部122之间形成第二间隙123。
每一第一齿状部112被插入至一第二间隙123，每一第二齿状部122被插入至一第一间隙113。通过在特定区域103设置突出于驱动电极本体111的第一齿状部112和突出于每一感应电极本体121的第二齿状部122，增加触控驱动电极110和触控感应电极120的耦合面积，改善特定区域103触控性能不佳的问题。
在本实施例中，第一齿状部112和第二齿状部122的形状均为矩形，具体请参阅图3。
其中，突出于一驱动电极本体111的第一齿状部112的个数为2，在其他实施例中，突出于一驱动电极本体111的第一齿状部112的个数可以为1或是其他自然数；在本实施例中，突出于每一感应电极本体121的第二齿状部122的个数等于1或者大于1。显示区除四角区域之外的区域内，触控驱动电极110与触控感应电极120的形状均为矩形。
在本实施例中，特定区域103为显示区的四角区域，在其他实施例中，特定区域103也可以为显示区的屏下摄像头区域，特定区域103在此不做限定，只要是触控驱动电极110和触控感应电极120面积较小的区域即可。
实施例2
本实施例中的触控显示面板100结构，也具有触控驱动电极110与触控感应电极120，其与实施例1中的对应结构大致相同，其相同的结构可参照实施例1中的对应描述，此处不再赘述。其中两者的主要不同之处在于，在本实施例中，在特定区域103内，第一齿状部112和第二齿状部122的形状均为梯形，具体请参阅图4。
在其他实施例中，第一齿状部112和第二齿状部122的形状还可以为其他形状，在此不做限定，只要能够增大触控驱动电极110和触控感应电极120之间的耦合电容即可。
本发明提供一种触控显示面板，通过在显示面板的四个角落区域设置突出于驱动电极本体的第一齿状部和突出于每一感应电极本体的第二齿状部，增加触控驱动电极和触控感应电极的耦合面积，以使达成触控性能规格，改善显示面板的四个角落区域触控性能不佳的问题，从而提升产品的市场竞争力。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例所提供的一种触控显示面板进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
