以触控类智能移动终端为例，随着智能移动终端的快速发展，超高屏占比的智能移动终端凭借其能够给用户带来极致的视觉体验，越来越受到更多厂商和消费者的推崇。然而，随着智能移动终端的显示屏占比越来越大，智能移动终端的显示屏下侧留给用户用于安全认证的指纹识别模块的空间也越来越小。在这种情况下，为了给用户带来更便捷的使用体验，有些厂商则考虑直接将电容式指纹识别模块设置在智能移动终端的触控显示区域中，以便用户能够同时在触控显示区域进行触控操作和指纹识别操作。
在上述场景中，当直接将电容式指纹识别模块设置在电容式触控显示区域中时，两者则会在其重叠区域相互干扰，导致该重叠区域中处于相对下层的区域被处于相对上层的区域屏蔽信号，进而使得该重叠区域中处于相对下 层的区域失效的问题。

本申请提供了一种触控显示面板，包括触控膜层以及指纹识别膜层，所述指纹识别膜层在触控膜层上的正投影位于所述触控膜层的预设镂空区域；其中触控膜层包括沿第一方向设置的触控驱动电极，以及沿第二方向设置的触控感应电极，触控驱动电极和触控感应电极交叉绝缘设置；且触控膜层中至少一个特定电极的两端通过信号传输线与第一驱动芯片连接，该至少一个特定电极包括被预设镂空区域截断的触控驱动电极，和/或触控感应电极。
本申请提供的触控显示面板，由于触控膜层中设置有预设镂空区域，且指纹识别膜层在触控膜层上的正投影位于触控膜层的预设镂空区域，这样这两个膜层之间便不会产生干扰，此外触控膜层中至少一个特定电极的两端均通过信号传输线与第一驱动芯片连接，该至少一个特定电极包括被预设镂空区域截断的触控驱动电极和/或触控感应电极，从而避免了被预设镂空区域截断的触控驱动电极和触控感应电极截断与第一驱动芯片的连接。
需要说明的是，本申请中所描述的预设镂空区域可以是根据指纹识别膜 层的大小在触控膜层中设置的，该预设镂空区域的形状可以由实际使用情况决定，本申请对此不做限定，只要该预设镂空区域能够使得指纹识别膜层能够设于其中即可。
基于上述简单描述了本申请提供的触控显示面板的核心构思，下面通过具体的实施方式详细说明本申请的构思。
请参阅图1，为本申请提供的触控显示面板的一种具体实施方式的结构示意图，包括触控膜层11以及指纹识别膜层12，该指纹识别膜层12在触控膜层上的正投影位于该触控膜层11的预设镂空区域；触控膜层11中至少一个特定电极的两端通过信号传输线与第一驱动芯片13连接，该至少一个特定电极包括被预设镂空区域截断的触控驱动电极，和/或，触控感应电极。
其中，触控膜层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。
可选的，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，如图1所示，则上述触控膜层中至少一个特定电极的两端通过信号传输线与第一驱动芯片13连接，具体而言，触控膜层中第一特定电极1111的两端通过第一信号传输线15与第一驱动芯片13连接，该第一特定电极1111为被预设镂空区域截断的触控感应电极，而触控膜层中第二特定电极1121的两端通过第二信号传输线16与第一驱动芯片13连接，该第二特定电极1121为被预设镂空区域截断的触控感应电极。
可选的，当至少一个特定电极包括被预设镂空区域截断的触控感应电极时，如图2所示，该预设镂空区域在19所示的位置区域时，被该预设镂空区域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截断的触控感应电极1122的两端通过信号传输线与第一驱动芯片13连接，以避免被预设镂空区域截断的触控感 应电极断开与第一驱动芯片13的连接。
可选的，当至少一个特定电极包括被预设镂空区域截断的触控驱动电极时，如图3所示，该预设镂空区域在20所示的位置区域时，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，因此可以仅将被该预设镂空区域截断的触控驱动电极1112的两端通过信号传输线与第一驱动芯片13连接，以避免被预设镂空区域截断的触控驱动电极断开与第一驱动芯片13的连接。
指纹识别膜层12包括沿第三方向设置的指纹驱动电极121，以及沿第四方向设置的指纹感应电极122，该指纹驱动电极121与指纹感应电极122交叉绝缘设置；且指纹驱动电极121通过第三信号传输线17与第二驱动芯片14连接，指纹感应电极122通过第四信号传输线18与第二驱动芯片14连接。需要说明的是，上述第一驱动芯片13和第二驱动芯片14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，即第一驱动芯片13和第二驱动芯片14可以为一个集成的驱动芯片。
可选的，对于所述指纹识别膜层12与触控膜层11之间的位置关系，当触控感应电极、触控驱动电极为同层设置时，指纹电极可以与触控膜层异层设置，也可以同层设置；当触控感应电极、触控驱动电极为异层设置时，指纹电极可以与触控感应电极和触控驱动电极中的一者同层，也可以异层设置。
可选的，在实际工艺制作过程中，为了简化工艺和制作流程，本申请实施例提供一种优选的方式，上述第一方向可以与第三方向相同，第二方向可以与第四方向相同，如图1所示。此外，上述第一方向与第三方向也可以不同，第二方向与第四方向也可以不同，比如第一方向与第三方向也可以以45°的角度相交，同时第二方向与第四方向也可以以45°的角度相交，或者其他角度大小也可以，本申请对此不做具体限定。
此外，本申请实施例中的触控显示面板还包括显示膜层，该显示膜层中设置有呈阵列式排布的多个发光子像素，由于触控膜层和指纹识别膜层设置在该显示膜层之上，为了不对显示膜层中的多个发光子像素造成遮挡，本申请实施例中的指纹识别膜层中指纹驱动电极以及指纹感应电极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。优选地，为了实现这一技术效果，本申请实施例中的指纹识别膜层的材料可以是宽度小于5微米的金属材料，或者，也可以选择透明导电材料。
需要说明的是，上述指纹识别膜层中指纹驱动电极以及指纹感应电极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的技术效果在实际应用中，可能会由于工艺水平的限制，不能达到完全不重叠的效果，因此可能会出现指纹识别膜层中指纹驱动电极以及指纹感应电极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部分重叠的情况，在这种情况下，为了避免指纹识别膜层对显示膜层中的发光子像素的遮挡，该指纹识别膜层的材料可以选择透明导电材料。
此外，由于第三信号传输线和第四信号传输线也位于显示膜层之上，为了避免该第三信号传输线和第四信号传输线对显示膜层中的发光子像素造成遮挡，从而影响显示效果，该第三信号传输线与第四信号传输线位于显示膜层的相邻发光子像素的缝隙处。在实际应用中，第三信号传输线与第四信号传输线的宽度往往是越细越好，其宽度在实际应用中往往要小于3微米。
需要说明的是，本申请实施例的触控膜层中的触控驱动电极和触控感应电极的形状不仅可以是图1和图4中所示的矩形形状，还可以是菱形的形状，且指纹识别膜层中的指纹驱动电极和指纹感应电极的形状也可以是菱形的形状。
可选地，在实际的制造工艺过程中，为了便于制造并简化工艺，本申请实施例中的触控膜层中除第一特定电极以外的触控驱动电极111的两端也可以通过第一信号传输线15与第一驱动芯片13连接，触控膜层中除第二特定 电极以外的触控感应电极112的两端也通过第二信号传输线16与第一驱动芯片13连接。如图4所示，为触控膜层中所有触控驱动电极111的两端均通过第一信号传输线15与第一驱动芯片13连接，且触控膜层中所有触控感应电极112的两端也都通过第二信号传输线16与第一驱动芯片13连接的示意图。
本申请提供的触控显示面板，由于触控膜层中设置有预设镂空区域，且指纹识别膜层在触控膜层上的正投影位于触控膜层的预设镂空区域，这样这两个膜层之间便不会产生干扰，此外触控膜层中至少一个特定电极的两端均通过信号传输线与第一驱动芯片连接，该至少一个特定电极包括被预设镂空区域截断的触控驱动电极和/或触控感应电极，从而避免了被预设镂空区域截断的触控驱动电极和触控感应电极截断与第一驱动芯片的连接。
以上为本申请提供的一种触控显示面板，基于该触控显示面板，本申请的实施例还提供一种触控显示装置，包括如上文所述的触控显示面板。
其中，该触控显示装置例如可以是智能移动终端的触控显示屏幕，但不限于此；只要其指纹识别膜层在触控膜层上的正投影位于触控膜层的预设镂空区域，均应在本申请的保护范围之内。
上述触控显示装置包括所述的触控显示面板。此外，该触控显示装置可以为手机、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。对于该触控显示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。
