在实际应用中，该指纹识别膜层可以只有一个，也可以有多个，设于在触控膜层的多个预设镂空区域中，本申请对此不作具体限定。
请参阅图3，为本申请实施例提供的触控膜层的结构示意图，该触控膜层15包括沿第一方向设置的触控驱动电极111，以及沿第二方向设置的触控感应电极112，该触控驱动电极111和触控感应电极112交叉绝缘设置；且触控膜层15中至少一个特定电极的两端通过信号传输线与触控驱动芯片11连接，该至少一个特定电极包括被预设镂空区域18截断的触控驱动电极，和/或，触控感应电极。
可选的，如图3所示，当至少一个特定电极包含触控驱动电极和触控感应电极时，为避免被预设镂空区域18截断的触控驱动电极1111和触控感应电极1121断开与触控驱动芯片11的连接，则上述触控膜层15中至少一个特定电极的两端通过信号传输线与触控驱动芯片11连接，具体而言，如图3所示，触控膜层中第一特定电极的两端通过第一信号传输线14与触控驱动芯片11连接，该第一特定电极为被预设镂空区域18截断的触控感应电极1111， 而触控膜层中第二特定电极的两端通过第二信号传输线13与触控驱动芯片11连接，该第二特定电极为被预设镂空区域18截断的触控感应电极1121。
可选的，如图4(a)所示，当至少一个特定电极包括被预设镂空区域19截断的触控感应电极时，由图4(a)可知，被该预设镂空区域19截断的特定电极为触控感应电极1122，而被该预设镂空区域19去除的触控驱动电极由于位于触控膜层的边缘位置，该预设镂空区域并不影响触控驱动电极，因此可以仅对被该预设镂空区域19截断的触控感应电极1122的两端通过信号传输线与触控驱动芯片11连接，以避免被预设镂空区域19截断的触控感应电极1122断开与控驱动芯片11的连接。
可选的，如图4(b)所示，当至少一个特定电极包括被预设镂空区域20截断的触控驱动电极时，由图4(b)可知，该预设镂空区域截断的特定电极为触控驱动电极1112，而被该预设镂空区域20区域的触控感应电极由于位于触控膜层的边缘位置，该预设镂空区域并不影响触控感应电极，因此可以仅将被预设镂空区域20截断的触控驱动电极1112的两端通过信号传输线与触控驱动芯片11连接，以避免被预设镂空区域20截断的触控驱动电极断开与触控驱动芯片11的连接。
可选地，该触控面板还可以具有显示功能，具体来说，该触控面板还可以包括显示膜层131，如图2所示，该显示膜层131中设置有呈阵列式排布的多个发光子像素1310，也就是图2所示的“R”“G”“B”。为了避免指纹识别膜层中的指纹识别图案遮挡显示膜层131中的发光子像素1310，本申请实施例中的指纹识别膜层在触控膜层上的正投影，与多个发光子像素1310在触控膜层上的正投影不重叠。
可选地，本申请实施例提供一种优选的实施方式，该指纹识别膜层包括第一指纹识别图案，为了避免该第一指纹识别图案遮挡显示膜层131中的发光子像素1310进而影响显示膜层131的显示，该第一指纹识别图案在显示膜层上的正投影，可以位于显示膜层131中相邻发光子像素的缝隙处。如图2 所示，为本申请实施例提供的第一指纹识别图案在显示膜层上的正投影位于显示膜层13中的相邻发光子像素的缝隙处的示意图，其中第一指纹识别图案是由图2中的沿第三方向设置的指纹驱动电极1511和沿第四方向设置的指纹感应电极1512形成的。
在实际应用中，由于指纹指标膜层中包括沿第三方向设置的指纹驱动电极1511，以及沿第四方向设置的指纹感应电极1512，且该指纹驱动电极1511与指纹感应电极1512之间交叉绝缘设置，如图2所示，为了保证指纹识别膜层有足够的识别灵敏度，该指纹识别膜层中的指纹驱动电极1511与指纹感应电极1512的线宽则不能太小。因此，本申请实施例中的相邻发光子像素的缝隙宽度范围可以是10μm-50μm之间，则指纹识别膜层中的多个指纹驱动电极1511与多个指纹感应电极1512的线宽应落入该相邻发光子像素的缝隙宽度范围内，如图2所示，指纹识别膜层中的至少三个指纹驱动电极1511的线宽或者至少三个指纹感应电极1512的线宽应落入该相邻发光子像素的缝隙宽度范围内。
在实际应用中，为了简化制作工艺，且为了能够满足第一指纹识别图案在触控膜层上的正投影位于显示膜层131中的相邻发光子像素的缝隙处，第三方向与第四方向通常以90°的角度相交，如图2所示。
可选地，由于显示膜层131中相邻发光子像素1310之间的缝隙不能太宽，太宽则会影响显示膜层131的显示，因此为了增加指纹识别膜层的识别灵敏度，本申请实施例中的指纹识别膜层的指纹驱动电极1511和指纹感应电极1512的线宽往往不能太窄，而如果指纹识别膜层的指纹驱动电极1511和指纹感应电极1512的线宽较宽，则会影响显示膜层131中发光子像素1310，进而影响显示膜层131的显示。本申请实施例为了解决这个问题，可以增加显示膜层的驱动电压和驱动电流，进而增加显示膜层131中各发光子像素1310的亮度来削弱指纹识别膜层对显示膜层131的影响。
由于显示膜层中相邻发光子像素之间的缝隙宽度有限，出于对指纹识别 膜层的识别灵敏度的考虑，本申请实施例还提供一种可选的实施方式，将现有技术中显示膜层中的多个发光子像素进行重新排布。如图5和图6所示，在显示膜层的发光子像素中设置至少一个空白子像素1，指纹识别膜层中包括至少一个第二指纹识别图案2，为了避免指纹识别膜层中的指纹识别图案遮挡显示膜层132中的发光子像素1320，该第二指纹识别图案2在触控膜层上的正投影与显示膜层132中空白子像素1在触控膜层上的正投影相重叠。也就是说，第二指纹识别图案2与显示膜层132中的空白子像素1在位置上一一对应，如图6所示。
如图7所示，第二指纹识别图案2放大后的结构示意图，该第二指纹识别图案2是由沿第三方向设置的指纹驱动电极1511和沿第四方向设置的指纹感应电极1512形成的。
如图5所示，为本申请实施例提供的第二种触控面板的结构示意图，包括触控膜层152，以及设于该触控膜层152的至少一个预设镂空区域中的指纹识别膜层2。为了不影响显示膜层132的显示效果，上述显示膜层132中可以设置多个空白子像素1，这些空白子像素1均匀分布在显示膜层132的发光子像素1320之间。
需要说明的是，上述第一种显示面板和第二种显示面板的结构还可以相互结合，也就是说，上述指纹识别膜层既可以包括第一指纹识别图案，也可以包括第二指纹识别图案，只要该第一指纹识别图案在触控膜层上的正投影，位于显示膜层中相邻发光子像素的缝隙处，且第二指纹识别图案在触控膜层上的正投影与显示膜层中空白子像素在触控膜层上的正投影重叠即可。也就是说，可以在现有技术的显示膜层中多个发光子像素呈阵列式排布的基础上，在显示膜层中设置一些空白子像素。
如图3所示，由于指纹识别膜层中包括指纹驱动电极1511和指纹感应电极1512，且指纹驱动电极1511和指纹感应电极1512则需要通过引线与指纹驱动芯片12连接，为了避免连接指纹驱动电极1511和指纹感应电极1512的 引线也就是连接指纹识别膜层的引线不遮挡显示膜层中发光子像素，本申请实施例中连接指纹识别膜层的引线在触控膜层上的正投影与显示膜层中发光子像素在触控膜层上的正投影不重叠。
需要说明的是，上述触控驱动芯片11和指纹驱动芯片12可以分别为触控膜层的驱动芯片和指纹识别膜层的驱动芯片，也就是这两个驱动芯片为两个不同的驱动芯片，也可以简化该触控显示面板的结构将这两个驱动芯片封装集成，即触控驱动芯片11和指纹驱动芯片12可以为一个集成的驱动芯片。
在实际应用中，该连接指纹识别膜层的引线往往是越细越好，其宽度往往要小于3μm。
可选地，出于制作工艺的复杂度、制作成本以及灵敏度的考虑，本申请实施例中的触控膜层和指纹识别膜层的材料包括下述至少一种：铜；银；钛；铝；钼,也可以是上述这几种材料的组合。
本申请提供的触控面板，由于触控膜层中设置有至少一个预设镂空区域，且指纹识别膜层在触控膜层上的正投影位于触控膜层的至少一个预设镂空区域，这样这两个膜层之间便不会产生干扰，因此能够实现指纹识别的全面屏方案。
以上为本申请提供的一种触控面板的制作方法，基于该制作方法，本申请还提供一种触控装置，该触控装置包括上述所述的触控面板。
其中，该触控装置，例如可以是有机电发光器件，但不限于此；只要该触控面板的指纹识别膜层在触控膜层上的正投影位于触控膜层的至少一个预设镂空区域中，均应在本申请的包含范围之内。
上述触控装置包括所述的触控显示面板。此外，该触控装置可以为手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪、智能穿戴设备等任何具有显示功能的产品或部件。对于该触控装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本申请的限制。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
