在本公开实施方式的显示面板PNL中，源漏金属层可以为一层，也可以根据需要设置为两层或者三层。在一种示例中，源漏金属层可以包括依次层叠于层间电介质层ILD远离衬底基板一侧的第一源漏金属层和第二源漏金属层，第一源漏金属层和第二源漏金属层之间可以夹设有绝缘层，例如夹设有钝化层和/或平坦化层。在另一种示例中，源漏金属层可以包括依次层叠于层间电介质层ILD远离衬底基板一侧的第一源漏金属层、第二源漏金属层、第三源漏金属层；第一源漏金属层和第二源漏金属层之间可以夹设有绝缘层，例如夹设有钝化层和/或树脂层；第二源漏金属层和第三源漏金属层之间可以夹设有绝缘层，例如夹设有钝化层和/或平坦化层。
可选地，驱动电路层F100还可以包括有钝化层，钝化层可以设于源漏金属层SD远离衬底基板BP的表面，以便保护源漏金属层SD。
可选地，驱动电路层F100还可以包括设于衬底基板BP与半导体层SEMI之间的缓冲材料层Buff，且半导体层SEMI、栅极层GT等均位于缓冲材料层远离衬底基板BP的一侧。缓冲材料层的材料可以为氧化硅、氮化硅等无机绝缘材料。缓冲材料层可以为一层无机材料层，也可以为多层层叠的无机材料层。
可选地，驱动电路层F100还可以包括位于源漏金属层SD和像素层F200之间的平坦化层PLN，平坦化层PLN可以为像素电极提供平坦化表 面。可选地，平坦化层PLN的材料可以为有机材料。
像素层F200可以设置有与像素驱动电路对应电连接的发光元件，发光元件可以作为显示面板的子像素。如此，像素层设置有阵列分布的发光元件，且各个发光元件在像素驱动电路的控制下发光。在本公开中，发光元件可以为有机电致发光二极管(OLED)、高分子有机电致发光二极管(PLED)、微发光二极管(Micro LED)、量子点-有机电致发光二极管(QD-OLED)、量子点发光二极管(QLED)或者其他类型的发光元件。示例性地，发光元件为有机电致发光二极管(OLED)，则该显示面板为OLED显示面板。如下，以发光元件为有机电致发光二极管为例，对像素层的一种可行结构进行示例性的介绍。
在该示例中，像素层F200可以设置于驱动电路层F200远离衬底基板F100的一侧，其可以包括依次层叠设置的像素电极层AND、像素定义层PDL、支撑柱层PS、有机发光功能层EL和公共电极层COML。其中，像素电极层AND在显示面板的显示区具有多个像素电极；像素定义层PDL在显示区具有与多个像素电极一一对应设置的多个贯通的像素开口，任意一个像素开口暴露对应的像素电极的至少部分区域。支撑柱层PS在显示区包括多个支撑柱，且支撑柱位于像素定义层PDL远离衬底基板F100的表面，以便在蒸镀制程中支撑精细金属掩模版(Fine Metal Mask，FMM)。有机发光功能层EL至少覆盖被像素定义层PDL所暴露的像素电极。其中，有机发光功能层EL可以包括有机电致发光材料层，以及可以包括有空穴注入层、空穴传输层、电子阻挡层、空穴阻挡层、电子传输层和电子注入层中的一种或者多种。可以通过蒸镀工艺制备有机发光功能层EL的各个膜层，且在蒸镀时可以采用精细金属掩模版或者开放式掩膜板(Open Mask)定义各个膜层的图案。公共电极层COML在显示区可以覆盖有机发光功能层EL。如此，像素电极、公共电极层COML和位于像素电极和公共电极层COML之间的有机发光功能层EL形成有机发电致光二极管F200D，任意一个有机电致发光二极管可以作为显示面板的一个子像素。
可选的，像素层F200还可以包括位于公共电极层COML远离衬底基板F100一侧的光取出层，以增强有机发光二极管的出光效率。
可选地，显示层EE还可以包括薄膜封装层TFE。薄膜封装层TFE设 于像素层F200远离衬底基板F100的表面，可以包括交替层叠设置的无机封装层和有机封装层。触控层TT设置于薄膜封装层TFE远离衬底基板BP的一侧。其中，无机封装层可以有效的阻隔外界的水分和氧气，避免水氧入侵有机发光功能层EL而导致材料降解。可选地，无机封装层的边缘可以位于***区。有机封装层位于相邻的两层无机封装层之间，以便实现平坦化和减弱无机封装层之间的应力。其中，有机封装层的边缘，可以位于显示区的边缘和无机封装层的边缘之间。示例性地，薄膜封装层TFE包括依次层叠于像素层F200远离衬底基板F100一侧的第一无机封装层CVD1、有机封装层INK和第二无机封装层CVD2。
图3为本公开实施方式的显示面板PNL的一种俯视结构图。参见图3，显示面板PNL可以包括显示区AA和围绕显示区AA的***区BB。其中，显示区AA可以包括主显示区AA2和主显示区AA2一侧的至少一个透光区AA1。透光区AA1的透光率大于主显示区AA2的透光率。示例性的，主显示区AA2环绕透光区AA1。
参见图4和图6，应用该显示面板PNL的显示装置可以包括至少一个感光组件C300。其中，感光组件C300可以与透光区AA1一一对应设置，且感光组件C300可以正对对应的透光区AA1，以便接收从透光区AA1透射的光线。感光组件C300可以具有用于感测光线的感光区域，感光区域在衬底基板BP上的正投影可以位于透光区AA1内。感光组件C300可以为一个或者多个光线传感器，例如可以为摄像头、光学指纹识别芯片、光强传感器等。在一些实施方式中，感光组件C300可以为一摄像头，例如可以为一个CCD(电荷耦合器件)摄像头。
可选地，参见图3，透光区AA1可以嵌于主显示区AA2中，即主显示区AA2环绕透光区AA1。当透光区AA1的数量为多个时，透光区AA1可以分散设置，也可以相邻设置。当然地，在本公开的其他实施方式中，透光区AA1也可以位于主显示区AA2的一侧；例如，透光区AA1的边缘可以与***区BB的内边缘部分交叠，使得透光区AA1设置于显示区AA的边缘位置。
可选地，任意一个透光区AA1的形状可以为圆形、长圆形(中间矩形、两端半圆形)、方形、菱形、正六边形或者其他形状。在本公开的一 种实施方式中，透光区AA1的形状可以为圆形或者长圆形。
透光区AA1的数量可以为一个，也可以为多个，以满足感光组件C300的设置为准。在一种示例中，透光区AA1的数量为一个。如此，显示装置可以设置一个感光组件C300，例如可以设置一个摄像头或者光学指纹识别芯片。在另一种示例中，透光区AA1的数量为多个。如此，该显示装置可以设置多个感光组件C300，任意两个感光组件C300可以相同或者不相同。示例性地，透光区AA1的数量为三个且相邻设置。如此，显示装置可以设置有与三个透光区AA1一一对应的不同的感光组件C300，例如设置有成像摄像头、深景摄像头、红外摄像头三种不同的感光组件C300。
在本公开实施方式中，可以采用不同的技术以保证透光区AA1的透光性能，例如采用开孔屏技术或者采用屏下摄像技术。
举例而言，在本公开的一些实施方式中，参见图4和图5，在主显示区AA2和透光区AA1内，像素层F200均可以设置有发光元件C200，以便使得主显示区AA2和透光区AA1均能够实现画面显示。显示装置通过在透光区AA1处设置摄像头，可以实现屏下摄像，提高显示装置的屏占比。
参见图5，在一种示例中，显示面板PNL在透光区AA1可以不设置像素驱动电路C100，以便降低像素驱动电路C100对透光率的影响，提高透光区AA1的透光率。位于透光区AA1的各个发光元件C200的像素驱动电路C100，可以设置于主显示区AA2内。进一步地的，位于透光区AA1的各个发光元件C200的像素电极F300D1包括相互连接的电极本体F300D11和电极延伸走线F300D12。其中，电极本体F300D11位于透光区AA1内且用于作为发光元件C200的阴极或者阳极；电极延伸走线F300D12设于主显示区AA2和透光区AA1，其一端与电极本体F300D11连接，另一端与该发光元件C200对应的像素驱动电路C100电连接。进一步的，电极延伸走线F300D12可以采用透明导电材料，例如采用透镜金属氧化物(例如氧化铟锡)。电极延伸走线F300D12的材料还可以与电极本体F300D11的材料相同且同层设置，这使得电极延伸走线F300D12与电极本体F300D11可以在相同的工序中制备出来。
换言之，在该示例中，本公开实施方式的显示面板PNL中的发光元 件C200根据所处的位置，可以分为位于主显示区AA2的第一发光元件C201和位于透光区AA1的第二发光元件C202。本公开的显示面板PNL中的像素驱动电路C100可以根据其所驱动的发光元件C200，分为用于驱动第一发光元件C201的第一像素驱动电路C101和用于驱动第二发光元件C202的第二像素驱动电路C102。其中，第一像素驱动电路C101的输出端与第一发光元件C201的像素电极F300D1电连接，第二像素驱动电路C102的输出端与第二发光元件C202的像素电极F300D1的电极延伸走线F300D12电连接。换言之，电极延伸走线F300D12的两端分别连接第二发光元件C202的像素电极F300D1的电极本体F300D11和第二像素驱动电路C102的输出端。可选的，主显示区AA2可以包括与透光区AA1相邻的辅助显示区，第二像素驱动电路C102可以设置于辅助显示区内。
当然的，在本公开的另一种示例中，第二发光元件C202和第二像素驱动电路C102可以均设置于透光区AA1中，且通过调整第二像素驱动电路C102之间的间隙和布图面积等方式来提高透光区AA1的透光率。
再举例而言，在本公开的另外一些实施方式中，参见图6，显示面板PNL在透光区AA1处设置有透光孔。进一步的，显示区AA还设置有围绕透光区AA1的封装区，以避免水氧从透光区AA1向主显示区AA2入侵、阻挡裂纹向主显示区AA2延伸等。
图7和图8为本公开实施方式中触控层TT的结构示意图。参见图7，触控层TT具有多个触控通道TS，这些触控通道TS包括多个沿第二方向DH延伸的第二信号通道Rx和多个沿第一方向DV延伸的第一信号通道Tx；第二方向DH和第一方向DV相交。在一种实施方式中，第二方向DH和第一方向DV中的一个为显示面板PNL的行方向(扫描走线延伸的方向)，另一个为列方向(数据电压走线延伸的方向)。示例性的，第二方向DH为显示面板PNL的行方向，第一方向DV为显示面板PNL的列方向。
参见图7，各个第一信号通道Tx和各个第二信号通道Rx限定出阵列分布的多个触控定位区TSA。通过触控定位区TSA的第一信号通道Tx和第二信号通道Rx之间互容而形成触控电容。在触控时，触控定位区TSA内的触控电容的电容值会响应触控物(例如手指)而改变，显示装置通过 检测不同触控定位区TSA中的触控电容的改变而判断触控位置。
在本公开的一种实施方式中，参见图7和图8，触控层TT包括依次层叠设置于显示层EE一侧的第一触控金属层TMA、触控绝缘层TMI和第二触控金属层TMB。第二信号通道Rx在第二触控金属层TMB具有沿第二方向DH依次排列的多个第二信号电极RxP；相邻两个第二信号电极RxP之间通过位于第一触控金属层TMA或者第二触控金属层TMB的导电结构电连接；第一信号通道Tx在第二触控金属层TMB具有沿第一方向DV依次排列的多个第一信号电极TxP；相邻两个第一信号电极TxP之间通过位于第一触控金属层TMA或者第二触控金属层TMB的导电结构电连接。参见图9，在触控定位区TSA中，第二信号电极RxP的边缘和第一信号电极TxP的边缘之间形成插指电容，该插指电容作为触控定位区TSA内的触控电容的一部分。
在一种示例中，参见图7和图9，在同一触控定位区TSA中，显示面板PNL包括分别属于相邻两个第一信号电极TxP的第一信号电极的第一部分TxPA和第一信号电极的第二部分TxPB、分别属于相邻两个第二信号电极RxP的第二信号电极的第一部分RxPA和第二部分RxPB；第一信号电极的第一部分TxPA和第二部分TxPB之间通过导电结构电连接，且第二信号电极的第一部分RxPA和第二部分RxPB之间电连接。在沿第二方向DH相邻的两个触控定位区TSA中，其中一个触控定位区TSA中的第二信号电极的第二部分RxPB与另一个触控定位区TSA中的第二信号电极的第一部分RxPA相邻且连接，共同组成一个第二信号电极RxP。这样，位于第二信号通道Rx一端的第二信号电极RxP可以仅包括第二信号电极的第一部分RxPA，位于第二信号通道Rx另一端的第二信号电极RxP可以仅包括第二信号电极的第二部分RxPB，非端部的第二信号电极RxP可以包括第二信号电极的第一部分RxPA和第二部分RxPB，第二信号电极的第一部分RxPA和第二部分RxPB分别位于相邻的两个触控定位区TSA中。在沿第一方向DV相邻的两个触控定位区TSA中，其中一个触控定位区TSA中的第一信号电极的第二部分TxPB与另一个触控定位区TSA中的第一信号电极的第一部分TxPA相邻且连接，共同组成一个第一信号电极TxP。这样，位于第一信号通道Tx一端的第一信号电极TxP可以仅 包括第一信号电极的第一部分TxPA，位于第一信号通道Tx另一端的第一信号电极TxP可以仅包括第一信号电极的第二部分TxPB，非端部的第一信号电极TxP可以包括第一部分TxPA和第二部分TxPB，第一信号电极的第一部分TxPA和第二部分TxPB分别位于相邻的两个触控定位区TSA中。
参见图10，第一信号通道Tx、第二信号通道Rx可以呈镂空设计，以减少对显示面板PNL出光的影响并降低对环境光线的反射。进一步的，第一信号通道Tx和第二信号通道Rx之间的间隙可以呈弯折形状而非直线，即使得相邻的第一信号电极TxP和第二信号电极RxP相互插接。这样，利于消除第一信号电极TxP和第二信号电极RxP之间的边界的可视程度，提高显示面板PNL的均一性。
触控层TT还可以设置有触控走线，触控走线可以设置于***区BB且与触控通道TS电连接，以便将第一信号通道Tx和第二信号通道Rx的信号传输至显示装置的控制组件；显示装置的控制组件可以根据触控走线传输的信号来确定触控位置。
在本公开的一种实施方式中，在第一信号电极TxP的第一部分TxPA和第二部分TxPB中，第一信号电极的第一部分TxPA靠近该第一信号通道Tx所连接的触控走线。换言之，位于第一信号通道Tx的端部的第一信号电极TxP与触控走线连接，该第一信号电极TxP为第一信号电极的第一部分TxPA。在第二信号电极RxP的第一部分RxPA和第二部分RxPB中，第二信号电极的第一部分RxPA靠近该第二信号通道Rx所连接的触控走线。换言之，位于第二信号通道Rx的端部的第二信号电极RxP与触控走线连接，该第二信号电极RxP为第二信号电极的第一部分RxPA。
在本公开实施方式中，参见图11，根据触控定位区TSA与透光区AA1的相对位置关系，可以将触控定位区TSA分为正常触控定位区NTSA和异构触控定位区MTSA。其中，正常触控定位区NTSA与透光区AA1不相交，异构触控定位区MTSA与透光区AA1相交。换言之，正常触控定位区NTSA中的第二信号电极RxP、第一信号电极TxP等结构均不与透光区AA1相邻，其结构可以保持完整性。异构触控定位区MTSA中的第二信号电极RxP和第一信号电极TxP，至少部分与透光区AA1相邻，且为 了避让透光区AA1而具有避让透光区AA1的缺口。在本公开的一些示例中，可以通过第二信号电极RxP的边缘或者第一信号电极TxP的边缘是否与透光区AA1直接相邻来确定第二信号电极RxP或者第一信号电极TxP是否设置了避让缺口；如果一个导电结构的边缘与透光区AA1不直接相邻，例如间隔有其他导电结构，则可以认为该导电结构保持完整而没有设置避让透光区AA1的避让缺口；如果一个导电结构的边缘与透光区AA1直接相邻，而可以认为该导电结构设置了避让透光区AA1的避让缺口。
在本公开的一种实施方式中，参见图9，在正常触控定位区NTSA中，第一触控金属层TMA设置有桥接部TxB，第一信号电极的第一部分TxPA和第二部分TxPB之间通过桥接部TxB连接；第二触控金属层TMB设置有连接部RxB，第二信号电极的第一部分RxPA和第二部分RxPB通过连接部RxB连接。这样，连接部RxB和桥接部TxB之间交叠而形成互容电容，该互容电容也是正常触控定位区NTSA中的触控电容的一部分。
在本公开的一种实施方式中，触控层TT可以采用FMLOC(Flexible Multi-Layer On Cell)技术来实现，即以显示层EE为基板来制备触控层TT，而非将触控基板粘贴至显示层EE。
图12-1为相关技术中，触控层TT避让透光孔AA1的局部原理示意图。图12-2为相关技术中，避让透光孔AA1后触控层TT的局部结构示意图。参见图12-1，触控层TT的触控通道TS需要避让透光区AA1，这导致至少一个触控通道TS会被透光区AA1隔断。
在相关技术中，参见图12-2，当显示面板PNL为采用开孔屏技术时，触控层TT可以设置环绕透光区AA1的转接走线(例如图12-2中的转接线TRW1和转接线TRW2)以使得被隔断的触控通道TS重新连接。然而，在环绕透光区AA1的位置，显示面板PNL因封装而不具有足够的平坦度，这使触控层TT容易因跨膜层设置转接走线而出现短路或者断路不良。不仅如此，转接走线会占用较大的布图空间，影响透光区AA1周围的第一信号电极TxP或者第二信号电极RxP的图案，进而影响触控性能。不同的转接走线之间会形成平板电容，例如转接线TRW1和转接线TRW2需要分别设置在第一触控金属层TMA和第二触控金属层TMB而在交叠位 置形成平板电容，这导致该异构触控定位区MTSA内的触控电容增大(响应触控动作时电容的变化量却基本不变)，影响触控性能。当显示面板PNL采用屏下摄像技术时，因透光区AA1没有边框而难以设置双层转接线。这些情况均导致，具有透光区AA1的显示面板PNL在采用FMLOC技术时，触控层TT的触控性能难以保持稳定可靠。
在本公开实施方式提供的显示面板PNL中，参见图11，可以根据触控通道TS与透光区AA1的相对位置关系而分为正常触控通道NTS和异构触控通道MTS。其中，将与透光区AA1不相邻的触控通道TS定义为正常触控通道NTS，将与透光区AA1相邻的触控通道TS定义为异构触控通道MTS。在本公开实施方式中，参见图13，至少一个异构触控通道MTS包括多个与显示区AA相邻的异构触控亚通道SubMTS。在异构触控通道MTS的多个异构触控亚通道SubMTS中，至少一个异构触控亚通道SubMTS保持连续。这样，在异构触控通道MTS可以在异构触控定位区MTSA内设置异构触控亚通道SubMTS而灵活地避让透光区AA1，避免设置转接走线或者减少转接走线的数量，尤其是避免设置双层转接走线而形成平板电容，进而减小或者避免所设置的转接走线对触控传感器的影响。在本公开中，异构触控亚通道SubMTS保持连续是指，异构触控亚通道SubMTS位于第二触控金属层TMB的相邻两个导电结构之间通过位于该两个导电结构之间的导电连接部连接(该导电连接部设置于第一触控金属层TMA或者第二触控金属层TMB)，而非采用沿透光区AA1边缘弧形设置的转接走线连接。
作为一种示例，第一信号通道Tx在一个异构触控定位区MTSA中可以设置多个第一信号亚通道SubTx。如果一个第一信号亚通道SubTx的子电极之间均通过位于第一触控金属层TMA的桥接部TxB连接，则认为该第一信号亚通道SubTx保持连续。如果一个第一信号亚通道SubTx的至少两个子电极之间通过沿透光区AA1边缘弧形设置的转接走线连接，则认为该第一信号亚通道SubTx没有保持连续。可以理解的是，在一些情形下，没有保持连续的异构触控亚通道SubMTS也可以借助转接走线保持电性上的联系(即正常传递触控信号)。
在本公开实施方式的显示面板PNL中，同一异构触控定位区MTSA 中设置有相交的两个异构触控通道MTS(即设置有第一信号通道Tx和第二信号通道Rx)。在一种示例中，同一异构触控定位区MTSA中的一个异构触控通道MTS具有多个异构触控亚通道SubMTS，另一个异构触控通道MTS不设置异构触控亚通道SubMTS(即异构触控亚通道SubMTS的数量为1)。在另一种示例中，同一异构触控定位区MTSA中，两个异构触控通道MTS均设置有多个异构触控亚通道SubMTS，两个异构触控通道MTS各自的异构触控亚通道SubMTS的数量可以相同或者不同，例如可以均为两个。在一种示例中，同一异构触控定位区MTSA中，一个异构触控通道MTS可以保持连续而另一个异构触控通道MTS可以通过围绕透光区AA1的转接走线保持电信号的连续。在另一种示例中，同一异构触控定位区MTSA中，两个异构触控通道MTS可以均保持连续。
在本公开的一些实施方式中，在异构触控定位区MTSA中，可以将一个电极分割为多个子电极，进而通过不同的子电极形成不同的异构触控亚通道SubMTS。
在本公开的一些实施方式中，异构触控定位区MTSA的数量可以为多个，例如可以为2～6个。示例性的，异构触控定位区MTSA的数量为四个，四个异构触控定位区MTSA排列成相邻的两行两列。
图14-1展示了本公开一种实施方式中触控层TT的局部结构的设计原理；图14-2展示了本公开一种实施方式中触控层TT的局部结构的示意图。
参见图14-2，在本公开的一种实施方式中，在至少一个异构触控定位区MTSA中，第一触控金属层TMA设置有桥接部TxB，第一信号电极的第一部分TxPA包括至少两个子电极SubTxPA，且至少一个第一信号电极的第一部分的子电极SubTxPA通过桥接部TxB与第一信号电极的第二部分TxPB电连接。
在一种示例中，最远离透光区AA1的第一信号电极的第一部分的子电极SubTxPA可以不设置避让透光区AA1的缺口而通过桥接部TxB与第一信号电极的第二部分TxPB连接。
可选的，在至少一个异构触控定位区MTSA中，第二触控金属层TMB设置有第二信号电极的第三部分RxPC和连接部RxB，连接部RxB与桥接部TxB交叠设置；沿第二方向DH，第二信号电极的第三部分RxPC夹 设于第一信号电极的第一部分的相邻两个子电极SubTxPA之间。第二信号电极的第一部分RxPA和第二部分RxPB中的一个，与相邻的第二信号电极的第三部分RxPC之间通过连接部RxB电连接；第二信号电极的第一部分RxPA和第二部分RxPB中的另一个，与相邻的第二信号电极的第三部分RxPC之间通过位于第一触控金属层TMA或者第二触控金属层TMB的转接线TRW电连接，或者通过连接部RxB连接。
在一种示例中，转接线TRW设置于第二触控金属层TMB，且转接线TRW与第一信号通道Tx之间具有间隙。
在一种示例中，转接线TRW沿透光区AA1的边缘设置。
参见图14-1所示的触控层TT的局部结构的设计原理，在不考虑透光区AA1的辅助设计状态(设计过程中的状态而非最终版图)下，至少一个异构触控定位区MTSA中的第一信号电极的第一部分TxPA被划分为多个第一信号电极的第一部分的子电极SubTxPA(示例的为两个)，第一信号电极的第二部分TxPB划分为与多个第一信号电极的第一部分的子电极SubTxPA一一对应的多个第一信号电极的第二部分的子电极SubTxPB(例如为两个)，且异构触控定位区MTSA中的桥接部TxB的数量与第一信号电极的第一部分的子电极SubTxPA的数量相同；第一信号电极的第一部分的子电极SubTxPA和第一信号电极的第二部分的子电极SubTxPB通过对应的桥接部TxB连接。异构触控定位区MTSA中的第二信号电极的第三部分RxPC与第二信号电极的第一部分RxPA、第二信号电极的第二部分RxPB通过不同的连接部RxB连接。在制备的显示面板PNL中(即在触控层TT的最终版图中，参见图14-2)，第一信号电极的第一部分的子电极SubTxPA、第一信号电极的第二部分的子电极SubTxPB和桥接部TxB位于透光区AA1的部分被去除，以使得第一信号电极的第一部分TxPA的剩余部分和第一信号电极的第二部分TxPB的剩余部分之间通过至少一个桥接部TxB连接。同时，第二信号电极的第一部分RxPA、第二信号电极的第二部分RxPB、第二信号电极的第三部分RxPC、连接部RxB位于透光区AA1的部分也被去除；第二信号电极的第一部分RxPA、第二信号电极的第三部分RxPC、第二信号电极的第二部分RxPB三者依次连接所形成的第二信号通道Rx被透光区AA1隔断时，则设置转接线TRW以使得 第二信号通道Rx保持畅通，且第一信号电极的第一部分的子电极SubTxPA还需要避让转接线TRW以避免形成平板电容。
在本公开中，为了表示方便，可以将图14-2中位于左上角的异构触控定位区MTSA命名为第一异构触控定位区MTSA。作为一种示例，参见图14-2，在第一异构触控定位区MTSA中，第一信号电极的第一部分TxPA包括两个沿第二方向DH排列的两个第一信号电极的第一部分的子电极SubTxPA，其中至少有一个第一信号电极的第一部分的子电极SubTxPA不受透光区AA1的影响而通过桥接部TxB与第一信号电极的第二部分TxPB连接，进而保证第一异构触控定位区MTSA中的第一信号通道Tx信号畅通。另一个第一信号电极的第一部分的子电极SubTxPA避让透光区AA1而具有缺口。在该第一异构触控定位区MTSA中，第一信号通道Tx如果不避让透光区AA1则应当具有两个异构触控亚通道SubMTS，每个异构触控亚通道SubMTS包括依次连接的第一信号电极的第一部分的子电极SubTxPA、桥接部TxB和第一信号电极的第二部分的子电极SubTxPB；为了避让透光区AA1，靠近透光区AA1的异构触控亚通道SubMTS被隔断，而远离透光区AA1的异构触控亚通道SubMTS保持连续。参见图14-2，在第一异构触控定位区MTSA中，第二信号通道Rx包括位于第二触控金属层TMB的第二信号电极的第一部分RxPA、第二信号电极的第二部分RxPB、第二信号电极的第三部分RxPC和连接部RxB，以及包括转接线TRW；其中，桥接部TxB和连接部RxB交叠设置。沿第二方向DH，第二信号电极的第一部分RxPA位于第一信号电极的第一部分的子电极SubTxPA远离透光区AA1的一侧，进而无需设置避让透光区AA1的缺口。沿第二方向DH，第二信号电极的第三部分RxPC位于第一信号电极的第一部分的相邻两个子电极SubTxPA之间，且设置有避让透光区AA1的缺口。第二信号电极的第一部分RxPA和第二信号电极的第三部分RxPC之间通过连接部RxB连接。第二信号电极的第二部分RxPB具有避让透光区AA1的缺口，且第二信号电极的第三部分RxPC与第二部分RxPB之间的连接被透光区AA1隔断。因此，第二信号电极的第二部分RxPB与第三部分RxPC之间通过沿透光区AA1边缘设置的转接线TRW连接，该转接线TRW可以设置于第一触控金属层TMA或者第二触 控金属层TMB。其中，第一信号电极与透光区AA1之间预留布线间隙，转接线TRW布设于该布线间隙中；这可以避免转接线TRW与第一信号通道Tx之间形成平板电容而过度增大第一异构触控定位区MTSA中的触控电容的电容值，进而在使得第二信号通道Rx和第一信号通道Tx信号保持畅通的情况下保证触控性能。
参见图14-2，在本公开的一种实施方式中，在至少一个异构触控定位区MTSA中，第一触控金属层TMA设置有桥接部TxB，第一信号电极的第二部分TxPB包括至少两个子电极SubTxPB，且至少一个第一信号电极的第二部分的子电极SubTxPB通过桥接部TxB与第一信号电极的第一部分TxPA电连接。进一步的，最远离透光区AA1的第一信号电极的第二部分的子电极SubTxPB可以不设置避让透光区AA1的缺口而通过桥接部TxB与第一信号电极的第一部分TxPA连接。
进一步的，在至少一个异构触控定位区MTSA中，第二触控金属层TMB设置有第二信号电极的第三部分RxPC和连接部RxB，连接部RxB与桥接部TxB交叠设置；沿第二方向DH，第二信号电极的第三部分RxPC夹设于相邻两个第一信号电极的第二部分的子电极SubTxPB之间。第二信号电极的第一部分RxPA和第二部分RxPB中的一个，与相邻的第二信号电极的第三部分RxPC之间通过连接部RxB电连接；第二信号电极的第一部分RxPA和第二部分RxPB中的另一个，与相邻的第二信号电极的第三部分RxPC之间通过位于第一触控金属层TMA或者第二触控金属层TMB的转接线TRW电连接，或者通过连接部RxB连接。
参见图14-1，在不考虑透光区AA1的辅助设计状态下，至少一个异构触控定位区MTSA中的第一信号电极的第一部分TxPA也划分为与多个第一信号电极的第二部分的子电极SubTxPB一一对应的多个第一信号电极的第一部分的子电极SubTxPA(例如为两个)，且异构触控定位区MTSA中的桥接部TxB的数量与第一信号电极的第二部分的子电极SubTxPB的数量相同；第一信号电极的第二部分的子电极SubTxPB和第一信号电极的第一部分的子电极SubTxPA通过对应的桥接部TxB连接。异构触控定位区MTSA中的第二信号电极的第三部分RxPC与第二信号电极的第一部分RxPA、第二信号电极的第二部分RxPB通过不同的连接部RxB连接。 在制备的显示面板PNL中，第一信号电极的第二部分的子电极SubTxPB、第一信号电极的第一部分的子电极SubTxPA和桥接部TxB位于透光区AA1的部分被去除，以使得第一信号电极的第二部分TxPB的剩余部分和第一信号电极的第一部分TxPA的剩余部分之间通过至少一个桥接部TxB连接为准。同时，第二信号电极的第一部分RxPA、第二信号电极的第二部分RxPB、第二信号电极的第三部分RxPC、连接部RxB位于透光区AA1的部分也被去除；第二信号电极的第一部分RxPA、第二信号电极的第三部分RxPC、第二信号电极的第二部分RxPB三者依次连接所形成的第二信号通道Rx被透光区AA1隔断时，则设置转接线TRW以使得第二信号通道Rx保持畅通，且第一信号电极的第二部分的子电极SubTxPB还需要避让转接线TRW以避免形成平板电容。
在本公开的示例中，为了表示方便，可以将图14-2中位于左下角的异构触控定位区MTSA命名为第二异构触控定位区MTSA。作为一种示例，在第二异构触控定位区MTSA中，第一信号电极的第二部分TxPB包括两个沿第二方向DH排列的两个第一信号电极的第二部分的子电极SubTxPB，其中至少有一个第一信号电极的第二部分的子电极SubTxPB不受透光区AA1的影响而通过桥接部TxB与第一信号电极的第一部分TxPA连接，进而保证第二异构触控定位区MTSA中的第一信号通道Tx信号畅通。另一个第一信号电极的第二部分的子电极SubTxPB所参与的异构触控亚通道SubMTS被透光区AA1隔断，例如该第一信号电极的第二部分的子电极SubTxPB所连接的第一信号电极的第一部分的子电极SubTxPA被透光区AA1隔断；当然的，该靠近透光区AA1的第一信号电极的第二部分的子电极SubTxPB自身在其他示例中也可以被透光区AA1隔断而具有缺口。

图14-1和图14-2示意了至少一个异构触控定位区MTSA中的第一信号通道Tx设置多个异构触控亚通道SubMTS以避免被透光区AA1完全隔断的方案及原理。上述设计构思及原理也可以在本公开的其他示例中应用，例如使得至少一个异构触控定位区MTSA中的第二信号通道Rx设置多个异构触控亚通道SubMTS以避免被透光区AA1完全隔断。图15-1示意了至少一个异构触控定位区MTSA中的第二信号通道Rx设置多个异构触控亚通道SubMTS以避免被透光区AA1完全隔断的局部设计的设计原理图；图15-2示意了至少一个异构触控定位区MTSA中的第二信号通道Rx设置多个异构触控亚通道SubMTS以避免被透光区AA1完全隔断的局部结构示意图。

作为一种示例，为了表述方便，将图15-2的左上角的异构触控定位区MTSA称为第三异构触控定位区MTSA。在第三异构触控定位区MTSA中，第二信号电极的第一部分RxPA包括两个沿第一方向DV排列的两个第二信号电极的第一部分的子电极SubRxPA，其中至少有一个第二信号电极的第一部分的子电极SubRxPA不受透光区AA1的影响而通过连接部RxB与第二信号电极的第二部分RxPB连接，进而保证异构触控定位区MTSA1中的第二信号通道Rx信号畅通。另一个第二信号电极的第一部分的子电极SubRxPA避让透光区AA1而具有缺口。
在第三异构触控定位区MTSA中，第一信号通道Tx包括位于第二触控金属层TMB的第一信号电极的第一部分TxPA、第一信号电极的第二部分TxPB、第一信号电极的第三部分TxPC，以及包括位于第一触控金属层TMA的桥接部TxB，并包括转接线TRW。其中，连接部RxB和桥接部TxB交叠设置。沿第一方向DV，第一信号电极的第一部分TxPA位于第二信号电极的第一部分的子电极SubRxPA远离透光区AA1的一侧，进而无需设置避让透光区AA1的缺口。沿第一方向DV，第一信号电极的第三部分TxPC位于相邻两个第二信号电极的第一部分的子电极SubRxPA之间，且设置有避让透光区AA1的缺口。第一信号电极的第一部分TxPA和第一信号电极的第三部分TxPC之间通过桥接部TxB连接。第一信号电极的第二部分TxPB具有避让透光区AA1的缺口，且第一信号电极的第三部分TxPC与第一信号电极的第二部分TxPB之间的连接被透光区AA1隔断。因此，第一信号电极的第二部分TxPB与第一信号电极的第三部分TxPC之间通过沿透光区AA1边缘设置的转接线TRW连接，该转接线TRW可以设置于第一触控金属层TMA或者第二触控金属层TMB。其中，第一信号电极的第三部分TxPC与第一信号电极的第二部分TxPB之间的第二信号电极的第一部分的子电极SubRxPA与透光区AA1之间预留布线间隙，转接线TRW布设于该布线间隙中；这可以避免转接线TRW与第二信号通道Rx之间形成平板电容而过度增大第三异构触控定位区MTSA中的触 控电容的电容值，进而在使得第一信号通道Tx和第二信号通道Rx信号保持畅通的情况下保证触控性能。
参见图15-2，在本公开的一种实施方式中，在至少一个异构触控定位区MTSA中，第二触控金属层TMB设置有连接部RxB，第二信号电极的第二部分RxPB包括至少两个第二信号电极的第二部分的子电极SubRxPB，且至少一个第二信号电极的第二部分的子电极SubRxPB通过连接部RxB与第二信号电极的第一部分RxPA电连接。进一步的，最远离透光区AA1的第二信号电极的第二部分的子电极SubRxPB可以不设置避让透光区AA1的缺口而通过连接部RxB与第二信号电极的第一部分RxPA连接。其余第二信号电极的第二部分的子电极SubRxPB中的至少部分可以避让透光区AA1而设置避让缺口，当然的，也可以不设置避让透光区AA1的缺口。

参见图19和图22，在本公开的一些实施方式中，异构触控亚通道SubMTS中的桥接部TxB或者连接部RxB还可以偏移以避让透光区AA1，以使得第一信号亚通道SubTx和第二信号亚通道SubRx中至少一个保持连续；这样，至少一个第一信号亚通道SubTx中具有多个桥接部TxB且各个桥接部TxB的分布轨迹不平行于第一方向DV(例如为折线)，或者至少一个第二信号亚通道SubRx中具有多个连接部RxB且各个连接部RxB的分布轨迹不平行于第二方向DH(例如为折线)。
参见图19和图22，在本公开的一种实施方式中，至少一个第一信号通道Tx具有在沿第一方向DV相邻的两个异构触控定位区MTSA中连续 的至少一条第一信号亚通道SubTx，连续的第一信号亚通道SubTx包括位于第二触控金属层TMB的电极(例如第一信号电极的第一部分的子电极SubTxPA、第一信号电极的第二部分的子电极SubTxPB)和连接电极且位于第一触控金属层TMA的桥接部TxB。连续的第一信号亚通道SubTx的各个桥接部TxB，在各自所在的异构触控定位区MTSA中的相对位置不同。在本公开的实施方式中，桥接部TxB在异构触控定位区MTSA中的相对位置，可以是指桥接部TxB与异构触控定位区MTSA的各个顶角或者各个边之间的距离。在一种示例中，可以采用桥接部TxB的位置向量来表示桥接部TxB在异构触控定位区MTSA中的相对位置关系，该位置向量可以包括四个距离参数，四个距离参数分别表示异构触控定位区MTSA的四个顶角与桥接部TxB的中心之间的距离。
图17、图18、图20和图21，为本公开的该实施方式的局部设计的设计原理图。在本实施方式的显示面板PNL的设计过程中，可以先不考虑透光区AA1而对异构触控定位区MTSA中的第一信号通道Tx和第二信号通道Rx进行设计(如图17和图20所示)，进而确定出各个桥接部TxB的初始位置；再将透光区AA1的因素考虑进来，并使得其中一个第一信号亚通道SubTx保持连续(如图18和图21所示)。在这个过程中，如图18和图21，如果预期被保持连续的第一信号亚通道SubTx被透光区AA1隔断，则可以改变该第一信号亚通道SubTx上的桥接部TxB的位置，并适应性的改变该第一信号亚通道SubTx的各个子电极的形状，使得该第一信号亚通道SubTx的各个桥接部TxB位于透光区AA1以外，进而使得该第一信号亚通道SubTx通过变形而保持连续。这种方式可以在降低各个第一信号通道Tx和第二信号通道Rx的设计难度的基础上，确保第一信号亚通道SubTx保持连续，使得该显示面板PNL在设计过程中具有更多的灵活性。
在一种示例中，参见图18和图19，异构触控定位区MTSA中的至少一个桥接部TxB可以沿第二方向DH方向偏移。这样，该被偏移的桥接部TxB所参与的第一信号亚通道SubTx中，各个桥接部TxB的分布轨迹不平行于第一方向DV。如此，在该示例的显示面板PNL中，参见图19，至少一第一信号通道Tx在沿第一方向DV相邻的两个异构触控定位区 MTSA中具有第一信号亚通道SubTx，该第一信号亚通道SubTx具有至少两个桥接部TxB，且该第一信号亚通道SubTx的桥接部TxB的分布轨迹不平行于第一方向DV。这种偏移方式，可以减小对第一信号通道Tx的各个电极的影响，并利于使得第一信号亚通道SubTx的电极保持尽量大的面积。
在另一种示例中，参见图21和图22，异构触控定位区MTSA中的至少一个桥接部TxB可以沿第一方向DV方向偏移。如此，沿第二方向DH相邻的两个异构触控定位区MTSA中，各个桥接部TxB的分布轨迹不平行于第二方向DH。具体的，参见图22，至少一个第二信号通道Rx包括位于沿第二方向DH相邻的两个异构触控定位区MTSA中的第二信号亚通道SubRx，该第二信号亚通道SubRx中的连接部RxB的分布轨迹(即与该第二信号亚通道SubRx交叠的各个桥接部TxB的分布轨迹)不平行于第二方向DH。
当然的，在本公开实施方式的其他示例中，异构触控定位区MTSA中的至少一个桥接部TxB可以同时在第一方向DV和第二方向DH上偏移。
在本公开的另外一种实施方式中，还可以对第二信号通道Rx的连接部RxB进行移动，以避免各个连接部RxB均被透光区AA1隔断。换言之，至少一个第二信号通道Rx包括位于沿第二方向DH相邻的两个异构触控定位区MTSA中的第二信号亚通道SubRx；所述第二信号亚通道SubRx包括位于所述第二触控金属层TMB的连接部RxB，且所述连接部RxB在各自所在的异构触控定位区MTSA中的相对位置不同。在一种示例中，至少一个所述第二信号亚通道SubRx的各个所述连接部RxB的分布轨迹不平行于所述第二方向DH。
图23为本公开的一种实施方式的局部设计的设计原理图。图24为本公开的一种实施方式中触控层TT的局部结构示意图。参见图24，在本公开的一种实施方式中，在至少一个异构触控定位区MTSA中，第一信号通道Tx包括多个第一信号亚通道SubTx；沿第一方向DV，至少一个第一信号亚通道SubTx靠近透光区AA1的端部与透光区AA1之间，间隔有第二信号通道Rx。
参见图23，在异构触控定位区MTSA中临近透光区AA1的临近位置 DD，因靠近透光区AA1而无法可靠的设置桥接部TxB，则可以不在该临近位置DD设置桥接部TxB。这样，原本应该作为第一信号亚通道SubTx一部分的电极无法通过桥接部TxB而作为第一信号亚通道SubTx的一部分，这些电极可以与第二信号通道Rx连接而作为第二信号通道Rx的一部分。这样，如图24所示，这使得至少部分第一信号亚通道SubTx与透光区AA1之间间隔有第二信号通道Rx。通过这种设置方式，因避让透光区AA1而导致尺寸太小的电极无需通过过孔与桥接部TxB连接，避免了在太靠近透光区AA1的位置设置过孔而导致的工艺困难；不仅如此，将这部分电极并入第二信号通道Rx可以提高第二信号通道Rx的稳定性，保证第二信号通道Rx畅通。
作为一种示例，参见图23，在不考虑透光区AA1的辅助设计状态下，异构触控定位区MTSA中的第一信号通道Tx包括两个第一信号亚通道SubTx；其中第一信号亚通道SubTx可以包括依次连接的第一信号电极的第一部分的子电极SubTxPA、桥接部TxB和第一信号电极的第二部分的子电极SubTxPB。异构触控定位区MTSA中的第二信号通道Rx包括依次连接的第二信号电极的第一部分RxPA、连接部RxB、第二信号电极的第三部分RxPC、连接部RxB和第二信号电极的第二部分RxPB。其中，第二信号电极的第三部分RxPC位于两个第一信号亚通道SubTx之间。在该示例的显示面板PNL中，异构触控定位区MTSA的第一信号通道Tx和第二信号通道Rx与透光区AA1相交的部分被去除。在图23左下角所示的异构触控定位区MTSA中，被透光区AA1隔断的第一信号亚通道SubTx的第一信号电极的第一部分的子电极SubTxPA设置有避让透光区AA1的缺口，且自身仅保留很小的部分。在理论上，该第一信号电极的第一部分的子电极SubTxPA可以通过桥接部TxB与第一信号电极的第二部分的子电极SubTxPB保持电连接，进而使得该被隔断的第一信号亚通道SubTx的端部临近透光区AA1。然而，该第一信号电极的第一部分的子电极SubTxPA在与桥接部TxB连接时，过孔距离透光区AA1非常近而不便设置。因此，在本示例的显示面板PNL中，图24左下角所示的异构触控定位区MTSA中的该本应作为第一信号电极的第一部分的子电极SubTxPA的子电极处可以不设置桥接部TxB，该子电极可不与第一信号电极的第二 部分的子电极SubTxPB保持连接，而是与同层设置且相邻的第二信号电极的第一部分RxPA和第二信号电极的第三部分RxPC连接，进而作为第二信号通道Rx的一部分。如此，在图24左下角所示的异构触控定位区MTSA中，被隔断的第一信号亚通道SubTx靠近透光区AA1的端部与透光区AA1之间间隔有第二信号通道Rx。这样，既避免了设置过孔，又保证了第二信号通道Rx的畅通。
在本公开的一种实施方式中，参见图9，在正常触控定位区NTSA，第一触控金属层TMA设置有桥接部TxB，第一信号电极的第一部分TxPA和第二部分TxPB之间通过桥接部TxB电连接；在正常触控定位区NTSA，第二触控金属层TMB设置有连接部RxB，第二信号电极的第一部分RxPA和第二部分RxPB之间通过连接部RxB电连接。
在正常触控定位区NTSA中，第一信号电极的第一部分TxPA、第一信号电极的第二部分TxPB和桥接部TxB的数量为一个，第二信号电极的第一部分RxPA、第二信号电极的第二部分RxPB和连接部RxB的数量为一个。换言之，在正常触控定位区NTSA中，第二信号通道Rx可以仅包括一个通路，第二信号通道Rx也可以进保持一个通路。在异构触控定位区MTSA中，第一信号通道Tx的第一信号亚通道SubTx在正常触控定位区NTSA重新合并，第二信号通道Rx的第二信号亚通道SubRx在正常触控定位区NTSA重新合并。换言之，各个异构触控定位区MTSA中可以设置有触控亚通道(例如第一信号亚通道SubTx或者第二信号亚通道SubRx)以避让透光区AA1，各个正常触控定位区NTSA中各个触控通道TS均不设置触控亚通道。
在本公开的另一种实施方式中，至少部分正常触控定位区NTSA中，触控通道TS也可以设置多条触控亚通道。例如，至少一个异构触控通道MTS所覆盖的各个触控定位区TSA均设置触控亚通道。
在一种示例中，参见图26，在至少部分正常触控定位区NTSA中，桥接部TxB的数量为多个，第一信号电极的第一部分TxPA包括与多个桥接部TxB一一对应的子电极SubTxPA，第一信号电极的第二部分TxPB包括与多个桥接部TxB一一对应的子电极SubTxPB；桥接部TxB与对应的第一信号电极的第一部分的子电极SubTxPA、第一信号电极的第二部分的 子电极SubTxPB电连接；在至少部分正常触控定位区NTSA中，第二触控金属层TMB还包括第二信号电极的第三部分RxPC；沿第二方向DH，第二信号电极的第三部分RxPC位于第一信号电极的第一部分的相邻的子电极SubTxPA之间，第二信号电极的第三部分RxPC通过不同的连接部RxB与第二信号电极的第一部分RxPA、第二信号电极的第二部分RxPB连接。换言之，在至少部分正常触控定位区NTSA中，第一信号通道Tx可以具有多个第一信号亚通道SubTx，第二信号通道Rx保持一个通道。进一步的，在各个正常触控定位区NTSA中，各个第一信号通道Tx均具有多个第一信号亚通道SubTx，每个第一信号亚通道SubTx包括依次连接的第一信号电极的第一部分的子电极SubTxPA、桥接部TxB和第一信号电极的第二部分的子电极SubTxPB。
在另一种示例中，在至少部分正常触控定位区NTSA中，连接部RxB的数量为多个，第二信号电极的第一部分RxPA包括与多个连接部RxB一一对应的子电极SubRxPA，第二信号电极的第二部分RxPB包括与多个连接部RxB一一对应的子电极SubRxPB；连接部RxB与对应的第二信号电极的第一部分的子电极SubRxPA、第二信号电极的第二部分的子电极SubRxPB电连接；在至少部分正常触控定位区NTSA中，第二触控金属层TMB还包括第一信号电极的第三部分TxPC；沿第一方向DV，第一信号电极的第三部分TxPC位于第二信号电极的第一部分的相邻的子电极SubRxPA之间，第一信号电极的第三部分TxPC通过不同的桥接部TxB与第一信号电极的第一部分TxPA、第一信号电极的第二部分TxPB连接。换言之，在至少部分正常触控定位区NTSA中，第二信号通道Rx可以具有多个第二信号亚通道SubRx，第一信号通道Tx保持一个通道。进一步的，在各个正常触控定位区NTSA中，各个第二信号通道Rx均具有多个第二信号亚通道SubRx，每个第二信号亚通道SubRx包括依次连接的第二信号电极的第一部分的子电极SubRxPA、连接部RxB和第二信号电极的第二部分的子电极SubRxPB。
