本公开的一些实施例提供了一种触控功能和图像显示功能兼具的触控显示装置，该触控显示装置可以包括但不限于手机、平板电脑、个人数字助理(personal digital assistant，PDA)、车载电脑等，本公开实施例对 触控显示装置的用途不作限制。
上述触控显示装置包括触控层组和显示面板。
在自容式触控技术的应用中，可以将用于实现触摸感测的多个膜层结构层叠设置形成触控层组，集成有触控层组的触控显示装置可实现触摸感测功能。参见图1，触控显示装置100具有触控感应区104，在触控感应区104内用户手指对触控显示装置100的触摸能够被感应到。触控层组包括基底层61和设置于基底层61上的多个感测电极62，基底层61用于承载多个感测电极62，感测电极62与地构成电容，即自电容。当手指触摸触控显示装置100的触控感应区104时，手指的电容将会叠加到感测电极62上，使感测电极62与地构成的电容发生变化。根据触摸前后多个感测电极62与地构成的电容值的变化量，便可以确定触摸点的坐标，实现触摸感测。感测电极62的图案为多条延伸方向不同的金属线连接形成的金属网格，行方向和列方向上相邻的两个感测电极62之间相互独立，即互不接触且不电连接。
如图1所示，触控显示装置100具有显示区101和位于显示区101至少一侧的周边区102，在触控显示装置中，显示区101与触控感应区的区域范围大致重合。例如，触控感应区可以与显示区101完全重合；又例如，触控感应区的区域范围可以大于显示区101，即显示区101的边沿均位于触控感应区的区域范围内，从而保证在显示区101的边界位置也能实现较好的触控效果。图1以周边区102包围显示区101为例进行示意。参见图2，由像素界定区域101b界定的多个亚像素101a设置于显示区101中。
其中，多个亚像素101a例如包括红色亚像素、绿色亚像素以及蓝色亚像素。亚像素101a的形状例如可以为矩形或如图13所示的六边形。
对于触控显示装置100的类型举例如下。触控显示装置100可以为液晶显示装置(liquid crystal display，简称LCD)；触控显示装置100也可以为自发光显示装置。其中，自发光显示装置例如可以为有机电致发光显示装置(organic light-emitting diode，简称OLED)或量子点电致发光显示装置(quantum dot light emitting diodes，简称QLED)。
在触控显示装置100为液晶显示装置的情况下，液晶显示装置包括盖板玻璃、触控层组、液晶显示面板以及背光组件。背光组件用于为液晶显示面板提供背光。如图3A、图3B以及图3C所示，液晶显示面板1的主要结构包括阵列基板11、对盒基板12以及设置在阵列基板11和对盒基板12之间的液晶层13。
如图3A、图3B以及图3C所示，阵列基板11的每个亚像素101a均设置有位于第一衬底110上的薄膜晶体管111和像素电极112。如图3A所示，阵列基板11还包括设置在第一衬底110上的公共电极113。像素电极112和公共电极113可以设置在同一层，也可以设置在不同层。当像素电极112和公共电极113设置在同一层时，如图3A所示，像素电极112和公共电极113之间设置有第一绝缘层114。在公共电极113设置在晶体管111和像素电极112之间的情况下，如图3A所示，公共电极113与晶体管111之间还设置有第二绝缘层115。在另一些实施例中，对盒基板12包括设置在第二衬底120上的公共电极113。
如图3A、图3B以及图3C所示，对盒基板12包括第二衬底120以及设置在第二衬底120上的彩色滤光层121，在此情况下，对盒基板12也可以称为彩膜基板(color filter，简称CF)。其中，彩色滤光层121至少包括位于红色亚像素的红色光阻单元、位于绿色亚像素的绿色光阻单元以及位于蓝色亚像素的蓝色光阻单元。对盒基板12还包括设置在第二衬底120上的黑矩阵图案122，黑矩阵图案122用于将红色光阻单元、绿色光阻单元以及蓝色光阻单元间隔开。
如图3A、图3B以及图3C所示，液晶显示面板1还包括设置在对盒基板12远离液晶层13一侧的上偏光片14以及设置在阵列基板11远离液晶层13一侧的下偏光片15。
在一些实施例中，如图3A所示，触控层组6设置在液晶显示面板1外，即，设置在盖板玻璃2和上偏光片14之间，在此情况下，触控显示装置称为外挂式触控显示装置，此时，上偏光片14复用做触控层组6的基底层。在另一些实施例中，如图3B和图3C所示，触控层组6设置在液晶显示面板1内，在此情况下，触控显示装置称为内嵌式触控显示装置。在触控层组6设置在液晶显示面板1内的情况下，可以是如图3B所示，触控层组6设置在上偏光片14和对盒基板12之间，在此情况下，触控显示装置称为外置式(on cell)触控显示装置，此时，对盒基板12复用做触控层组6的基底层。也可以是如图3C所示，触控层组6设置在第一衬底110和第二衬底120之间，例如设置在第一衬底110上，在此情况下，触控显示装置称为嵌入式(in cell)触控显示装置，此时，阵列基板11复用做触控层组6的基底层。
在触控显示装置100为自发光显示装置的情况下，如图4A和图4B 所示，自发光显示装置的主要结构包括依次设置的自发光显示面板3、触控层组6、偏光片4、第一光学胶(optically clear adhesive，简称OCA)5和盖板玻璃2。
其中，自发光显示面板3包括显示用基板31和用于封装显示用基板31的封装层32。此处，封装层32可以为封装薄膜，也可以为封装基板。
如图4A和图4B所示，上述的显示用基板31在每个亚像素101a包括设置在第三衬底310上的发光器件和像素驱动电路，像素驱动电路包括多个晶体管111。发光器件包括第一电极311、发光功能层312以及第二电极313，第一电极311和作为驱动晶体管的晶体管111的漏极电连接。显示用基板31还包括像素界定层(pixel definition layer，简称PDL)314，像素界定层314包括多个开口区，一个发光器件设置在一个开口区中。
在一些实施例中，上述发光功能层312包括发光层。在另一些实施例中，上述发光功能层312除包括发光层外，还包括电子传输层(election transporting layer，简称ETL)、电子注入层(election injection layer，简称EIL)、空穴传输层(hole transporting layer，简称HTL)以及空穴注入层(hole injection layer，简称HIL)中的一层或多层。
如图4A所示，显示用基板31还包括设置在晶体管111和第一电极311之间的平坦层315。
本领域技术人员应该明白，在触控显示装置100为自发光显示装置的情况下，触控显示装置100更容易制作成柔性显示装置，此时，第三衬底310为柔性衬底。
在触控显示装置100为自发光显示装置的情况下，在一些实施例中，如图4A所示，触控层组6直接设置在封装层32上，即，触控层组6和封装层32之间不设置其它膜层，封装层32复用为触控层组6的基底层。在另一些实施例中，如图4B所示，触控层组6设置在基板7上，基板7通过第二光学胶8贴附在封装层32上，基板7复用做触控层组6的基底层。此处，如图4A所示，在触控层组6直接设置在封装层32上的情况下，触控显示装置100的厚度较小，有利于实现轻薄化。
本公开实施例还提供一种触控层组，可以应用于上述的触控显示装置100中。当然，该触控层组也可以应用于其它的触控装置中。
示例性地，参见图1，触控层组6还包括设置于基底层61上的多条有效触控走线63。至少部分(也可以是全部)上述多条有效触控走线63中，至少 一条(例如，可以是每条)有效触控走线63的延伸方向平行于第一方向，且多条有效触控走线63沿第二方向排列，第二方向与第一方向交叉。有效触控走线63被配置为传输感测信号，每条有效触控走线63与一个感测电极62耦接。具体的，如图5所示，第一方向为Y方向，第二方向为X方向，第一方向与第二方向垂直。对有效触控走线63的形状不做过多限制，有效触控走线63可以为平行于Y方向的直线，也可以为包括多个弯折点的弯折线，弯折线的延伸方向平行于Y方向，即弯折线的起点和终点的连线平行于Y方向。
至少一个(例如，可以是每个)感测电极62与至少一条有效触控走线63耦接。示例性地，至少部分(也可以是全部)上述多个感测电极62中，每个感测电极62可以仅与一条有效触控走线63耦接，也可以与多条有效触控走线63耦接，对此不做过多限制。当每个感测电极62与多条有效触控走线63耦接时，多条有效触控走线63并联，等效电阻值较小，对感测信号的电位产生的影响也较小，有利于提高感测结果的准确性。在本公开的记载中，为了表述的清晰简明，以每个感测电极62与一条有效触控走线63耦接为例进行说明。
在触控层组6中，参见图5，每个感测电极62包括沿第二方向排列的多条感测主线621，至少一条(例如，可以是每条)感测主线621的延伸方向平行于第一方向，且由多条第一感测线段621a和多条第二感测线段621b交替连接形成，至少一条(例如，可以是每条)第一感测线段621a平行于第一方向，至少一条(例如，可以是每条)第二感测线段621b倾斜于第一方向。具体的，交替连接可以是一条第一感测线段621a和与其一端连接的多条第二感测线段621b沿第一方向重复分布，也可以是一条第一感测线段621a和与其两端分别连接的至少两条(例如，可以是多条)第二感测线段621b沿第一方向重复分布，位于第一感测线段621a两端的第二感测线段621b排布方式不同。示例性地，参见图5，感测主线621的延伸方向平行于Y方向，第一感测线段621a为沿Y方向延伸的直线段，第二感测线段621b为不沿Y方向延伸的斜向线段，第二感测线段621b的延伸方向与第一感测线段621a的延伸方向之间存在夹角，该夹角为钝角。当然，该夹角也可以为锐角，对此不做限制。由多条第一感测线段621a和多条第二感测线段621b交替连接形成的感测主线621有多种连接方式。
感测主线有多种设置方式。例如，参见图6中的(a)，每条感测主线621包括交替连接的多条第一感测线段621a和多条第二感测线段621b，除感测主线621的线端处外，每条第一感测线段621a的两端分别与一条第二感测线段 621b耦接，同时每条第二感测线段621b的两端分别与一条第一感测线段621a耦接。又例如，参见图6中的(b)，除感测主线621的线端处外，每条第一感测线段621a的两端分别与两条第二感测线段621b耦接，同时每条第二感测线段621b的两端分别与一条第一感测线段621a耦接。再例如，参见图6中的(c)，除感测主线621的线端处外，每条第一感测线段621a的两端分别与一条第二感测线段621b耦接，感测主线621中部分第二感测线段621b的一端与一条第一感测线段621a耦接同时另一端与一条第二感测线段621b耦接，感测主线621中的其他第二感测线段621b的两端分别与两条第二感测线段621b耦接。还例如，参见图6中的(d)，除感测主线621的线端处外，每条第一感测线段621a的两端分别与一条第二感测线段621b耦接，每条第二感测线段621b的一端与一条第一感测线段621a耦接，另一端与一条第二感测线段621b耦接。感测主线621还可以为其他设置方式，对此不做过多限制。
参见图5，每个感测电极62还包括与至少一条(例如，可以是每条)感测主线621连接的多条第三感测线段622，至少一条(例如，可以是每条)第三线段622倾斜于所述第一方向。示例性地，第三感测线段622为不沿Y方向延伸的斜向线段，第三感测线段622的延伸方向与Y方向之间存在夹角，该夹角为钝角。当然，该夹角也可以为锐角，对此不做限制。
示例性地，参见图5，每条感测主线621中的第一感测线段621a的一端除了与第二感测线段621b连接外，还与至少一条(例如，可以是一条，也可以是两条，对此不做限制)第三感测线段622连接，与同一条第一感测线段621a的一端连接的第二感测线段621b和第三感测线段622位于第一感测线段621a的不同侧。多条第三感测线段622与感测主线621的连接设置能够使感测电极62内部的感测面积扩大，具有更高的触控感应量，有利于提升触控感应效果。例如，感测主线621中的部分第一感测线段621a的一端与一条第二感测线段621b连接，还与两条第三感测线段622连接，且第二感测线段621b位于第一感测线段621a的一侧，两条第三感测线段622位于第一感测线段621a的另一侧。第一感测线段621a的另一端同样与一条第二感测线段621b和两条第三感测线段622连接，与第一感测线段621a的不同端连接的第三感测线段622分别位于第一感测线段621a的两侧。又例如，继续参见图5，感测主线621中的部分第一感测线段621a的一端与两条第二感测线段621b连接，还与一条第三感测线段622连接，两条第二感测线段621b位于第一感测线段621a的一侧，第三感测线段622位于第一感测线段621a的另一侧。第一 感测线段621a的另一端同样与两条第二感测线段621b和一条第三感测线段622连接，与第一感测线段621a的不同端连接的第三感测线段622分别位于第一感测线段621a的两侧。
参见图5，上述的感测电极62中，其中，多条第三感测线段622中的至少一条(例如，可以是多条)具有自由线端。自由线端即为与其他线端互不接触的线端。例如，部分第三感测线段622的一端与一条感测主线621连接，另一端与其他线端保持相互独立。
参见图7，多个感测电极62包括沿第一方向相邻的第一感测电极62A和第二感测电极62B，第一感测电极62A和第二感测电极62B中，同一延伸方向上的两条感测主线621之间的断点位于其中一条感测主线621一端的第二感测线段621b上。示例性地，在Y方向上任意相邻的两个感测电极62依次为第一感测电极62A和第二感测电极62B，第一感测电极62A所包括的每条感测主线621在第二感测电极62B中均有一条对应的感测主线621与其延伸方向为同一延伸方向。参见前述内容，延伸方向为同一延伸方向的多条感测主线621可以在一条延伸方向与Y方向平行且穿过沿Y方向排布的多个感测电极62的金属线上设置多个断点得到，同理，穿过第一感测电极62A和第二感测电极62B的多条金属线被多个断点划分为分别属于相邻两个感测电极62的多条感测主线621。上述断点可以位于第一感测电极62A中感测主线621靠近第二感测电极62B一端的第二感测线段621b上，或者位于第二感测电极62B中感测主线621靠近第一感测电极62A一端的第二感测线段621b上，只要位于倾斜的第二感测线段621b的线端处即可。
多条感测主线621及与多条感测主线621连接的多条第三感测线段622所限定的范围为感测电极62的感测范围，每条设置有断点的感测主线621具有两个线端，多条感测主线621具有多个线端，靠近感测主线621线端的多条第三感测线段622和多个线端所限定的位置为感测电极62的边界位置。感测电极62在其边界位置处也具有多个自由线端，每个自由线端为一个第二感测线段621b的一端。
由于金属线具有一定的厚度，同时受制于现有工艺水平，所形成金属线的侧面为坡面，金属线设置断点得到的多条金属线段的侧面也为坡面。当处于亮度较高的环境中时，金属线段的侧面会对光线进行反射，反光强度与金属线段的侧面长度有关，金属线段的侧面长度越长，反光面积越大，反光强度越强，反之则越弱。设置有断点的金属线段的侧面长度小于未设置断点的金属线段的侧面长度，相应的反光强度也比未设置断点的金属线段的侧面弱。 当设置有断点的金属线段和未设置断点的金属线段同时存在时，其金属线段的侧面长度差异导致出现反光强度差异，当从垂直于该金属线段侧面的方向看向触控显示装置时，该反光强度差异可被用户视觉上感受到，表现为显示mura，影响触控显示装置的显示效果。将能够观察到金属线侧面反光、垂直于金属线段反光侧面的角度称为可视角度。
参见图7，具有自由线端的多条第三感测线段622可以看做是在第三感测线段622的一端设置了断点使得第三感测线段622与其他线端相互独立得到的。结合上述，参见图7，在本公开的实施例中，断点均设置于倾斜于第一方向的斜向金属线段上，而平行于第一方向的第一感测线段621a上不设置断点，这样只存在垂直于斜向金属线段(也即倾斜于第一方向)的可视角度，不会新增因断点设置在第一感测线段621a上而出现的垂直于第一方向的可视角度，从而能在通过第三感测线段622实现感测面积增大的前提下，尽可能避免新增反光强度差异的可视角度，以降低可视化风险。
示例性地，至少一条(例如，可以是每条)第三感测线段622平行于一条第二感测线段621b。例如，参见图7，部分第一感测线段621a的每个线端均与一条第二感测线段621b和一条第三感测线段622连接，与同一个线端连接的一条第二感测线段621b和一条第三感测线段622位于该第一感测线段621a的两侧，且与一个线端连接的一条第三感测线段622和与另一个线端连接的一条第二感测线段621b相平行。
示例性地，参见图7，一条(例如每条)有效触控走线63包括至少一个(例如，可以是一个或多个)耦接部631，至少一个(例如每个)耦接部631与一个感测电极62电连接。除至少一个耦接部631外，该有效触控走线63在基底层61上的正投影与各个感测电极62在基底层61上的正投影无重叠区域。例如，参见图1，一条有效触控走线63依次穿过多个感测电极62(例如，一列感测电极62，以一列设置四个感测电极62为例)，四个感测电极62中仅有一个感测电极62与该有效触控走线63耦接，其他感测电极62并不与该有效触控走线63电连接。由于一条有效触控走线63仅与一个感测电极62电连接，因而有效触控走线63所包括的至少一个(例如，可以是一个或多个)耦接部631在基底层61上的正投影位于与该有效触控走线63耦接的感测电极62所限定范围在基底层61上的正投影内。被该有效触控走线63穿过但不与其耦接的多个感测电极62与该有效触控走线63在基底层61上的正投影不存在重叠区域。
耦接部631为有效触控走线63的一部分，对耦接部631的形状不做过多 限定，例如，耦接部631在基底层61上的正投影可以仅与多条第三感测线段622中的任意一条的至少部分(例如可以仅为线端部分，也可以为整条第三感测线段)在基底层61上的正投影重叠。具体的，参见图7，耦接部631在基底层61上的正投影与一条第三感测线段622在基底层61上的正投影重叠。
当不与有效触控走线63电连接的感测电极62在基底层61上的正投影与该有效触控走线63在基底层61上的正投影存在重叠区域时，具有重叠区域的各个金属线段之间会产生耦合电容，即寄生电容。寄生电容的存在会增大感测电极62的电容负载，不利于触控报点率和信噪比的提升。而本公开实施例中，不与有效触控走线63耦接的感测电极62在基底层61上的正投影与有效触控走线63在基底层61上的正投影无重叠区域，能够降低感测电极62的电容负载，从而能够避免出现上述问题。同时，由于每条有效触控走线63与一个感测电极62耦接，因此即使该有效触控走线63的耦接部631和与其耦接的感测电极62在基底层61上的正投影有重叠区域，有效触控走线63和该感测电极62之间也不会产生耦合电容。
参见图7，可以理解的是，由于有效触控走线63的延伸方向与感测主线621的延伸方向相同，有效触控走线63的延伸方向与第三感测线段622的延伸方向不同，为了保证感测电极62的感测面积以及布线的合理性，需要使有效触控走线63与感测主线621的位置在第二方向上错开，从而使得感测主线621在感测电极62中的分布区域尽可能大的同时，避免有效触控走线63与感测主线621在基底层61上的正投影存在重叠区域。进一步的，为了使感测电极62的感测面积尽可能大，在考虑工艺允许误差(overlay)的情况下，应尽可能保留第三感测线段622，也即具有自由线端的第三感测线段622的端点处具有避让设计，该避让设计可使第三感测线段622的端点距离有效触控走线63尽可能小，同时又能避免有效触控走线63与第三感测线段622在基底层61上的正投影存在重叠区域。
具体的，参见图7，延伸方向相同的第三感测线段622包括一端为自由线端的第一类第三感测线段622a和两端均不为自由线端的第二类第三感测线段622b，第一类第三感测线段622a的长度为d1，第二类第三感测线段622b的长度为d2。具体的，第一类第三感测线段622a的一端为自由线端，即第一类第三感测线段622a的一端为了避免与有效触控走线63在基底层61上的正投影存在重叠区域而存在避让设计，因此第一类第三感测线段622a的长度为d1小于第二类第三感测线段622b的长度d2。继续参见图7，为了使感测面积尽可能大，应尽可能多地设置第一类第三感测线段622a，因此第一类第三感测 线段622a的数量远多于第二类第三感测线段622b的数量。
参见图7，相邻的两个感测电极62的金属线间的断点均设置在感测电极62感测主线621的第二感测线段621b端部。由于断点的存在，设置有断点的第二感测线段621b相比于未设置断点的第二感测线段621b长度会减小，减小的长度为s1。存在避让设计的第一类第三感测线段622a第三感测线段622相比于不存在避让设计的第二类第三感测线段622b第三感测线段622长度也会减小，减小的长度为s2，s2＝d2-d1。
由于避让设计要尽可能保留第一类第三感测线段622a，而断点的设置需要保证相邻的两个感测电极62的感测主线621完全相互独立，因此断点对长度的减小幅度大于避让设计对长度的减小幅度，也即s1＞s2。同理，对第一感测线段621a而言，若在第一感测电极62A感测电极62和第二感测电极62B感测电极62中，同一延伸方向上的两条感测主线621之间的断点位于其中一条感测主线621一端的第一感测线段621a上，那么未设置断点的第一感测线段621a与设置有断点的第一感测线段621a的长度之差为s1。
继续参见图7，结合前述内容，由于每条第三感测线段622与一条第二感测线段621b相平行，因此第三感测线段622侧面反光的可视角度与第二感测线段621b侧面反光的可视角度相同，为第一可视角度；第一感测线段621a侧面反光的可视角度与第二感测线段621b和第三感测线段622的可视角度不同，第一感测线段621a侧面反光的可视角度为第二可视角度。在第一可视角度下，设置有断点的第二感测线段621b和第一可视角度下多条未设置断点的第二感测线段621b之间的长度差异为s1，由于第一类第三感测线段622a的数量远多于第二类第三感测线段622b的数量，因此设置有断点的第二感测线段621b和在第一可视角度下与其平行的多条第三感测线段622的长度差异可以视作设置有断点的第二感测线段621b和在第一可视角度下与其平行的多条第一类第三感测线段622a的长度差异，为s1-s2。而在第二可视角度下，长度差异为s1，显然，s1＞s1-s2。可见在感测电极62中，第一可视角度下的总长度差异更小，也即金属线段的侧面总长度差异更小，相应的由于金属线段的侧面长度差异导致的反光强度差异也就更小，从而能够避免显示mura的存在，使得触控显示装置实现更好的显示效果。
示例性地，在触控层组中，多条第二感测线段621b包括多条第一斜向线段L1和多条第二斜向线段L2，第一方向沿顺时针到一条第一斜向线段L1的延伸方向的角度为锐角，第一方向沿顺时针到一条第二斜向线段L2的延伸方向的角度为钝角。例如，参见图7，倾斜于第一方向的第二感测线段621b可 划分为第一斜向线段L1和第二斜向线段L2，第一斜向线段L1和第二斜向线段L2的倾斜方向即延伸方向不同，与一条第一感测线段621a连接的一条第一斜向线段L1和一条第二斜向线段L2均位于该第一感测线段621a的同一侧，且分别位于该第一感测线段621a的两端。在符合上述对第一斜向线段L1和第二斜向线段L2限制的情况下，多条第一斜向线段L1的延伸方向可以相同，也可以不同，多条第二斜向线段L2的延伸方向可以相同，也可以不同，对此不作过多限制。
第一感测电极62A和第二感测电极62B之间的多个断点中，一部分断点位于第一斜向线段L1上，另一部分断点位于第二斜向线段L2上。具体的，参见图7，除感测主线621的线端处以外，每条第一感测线段621a的一端与至少一条(例如，可以是一条)第一斜向线段L1连接，另一端与至少一条(例如，可以是一条)第二斜向线段L2连接。由于第一斜向线段L1和第二斜向线段L2的延伸方向不同，其可视角度也不相同，将第一感测电极62A和第二感测电极62B之间的多个断点分散地设置在第一斜向线段L1和第二斜向线段L2上，在一个可视角度下只有部分断点会导致产生可视化风险，其余断点并不会对该可视角度下的显示效果造成影响，相当于减小了总长度差异，从而能够降低反光强度差异所导致的可视化风险，有利于显示效果的提升。
示例性地，在触控层组中，第一感测电极62A和第二感测电极62B之间的多个断点，相间分布于第一斜向线段L1和第二斜向线段L2上。例如，参见图8，沿第二方向相邻的两条感测主线621上的断点相间分布在在延伸方向不同的第一斜向线段L1和第二斜向线段L2上，即在X方向上任意相邻的两条感测主线621中，一条感测主线621的断点设置在第一斜向线段L1上，另一条感测主线621的断点设置在第二斜向线段L2上。当感测主线621的总数为n、n为偶数时，在一行感测电极62的边界位置处断点的总数也为n，n/2个断点分布在沿一个延伸方向延伸的第一斜向线段L1上，其余n/2个断点分布在沿另一个延伸方向延伸的第二斜向线段L2上。将断点交替设置在沿不同方向延伸的第二感测线段621b上，在一个可视角度下只有n/2个存在可视化风险的断点，断点的密度减小，多个断点的分布更加分散，从而能够进一步降低可视化风险，有利于显示效果的提升。如上所述，当感测主线621的总数为n、n为奇数时，在沿其中一个延伸方向延伸的第二感测线段621b上均匀分布有(n-1)/2或(n+1)/2个断点，同样存在上述的有益效果，在此不再赘述。
示例性地，参见图9，上述的触控层组还包括沿第二方向与第一感测电极 62A相邻的第三感测电极62C。第一感测电极62A中的边缘感测主线上设置有至少一个断点，至少一个断点将边缘感测主线分割成多条断线，多条断线中与第一感测电极62A不连接的至少一条断线与第三感测电极62C连接。其中，边缘感测主线621为第一感测电极62A最靠近第三感测电极62C的一条感测主线621，至少一个断点(例如，可以是三个)均位于第一感测电极62A中的边缘感测主线的第二感测线段621b上。例如，在X方向上任意相邻的两个感测电极62依次为第一感测电极62A和第三感测电极62C。第一感测电极62A的多条感测主线621中最靠近的第三感测电极62C的一条为边缘感测主线，该边缘感测主线621上设置有至少一个(例如，可以是两个)断点，将完整的边缘感测主线621划分为三条断线，其中两条断线与第一感测电极62A耦接，另一条断线与第三感测电极62C耦接，使得第一感测电极62A和第三感测电极62C的边界相啮合，当边界区域存在触摸位置时，该触摸位置可被第一感测电极62A和第三感测电极62C感测到，具有较大的触控感应量，能够提升感测效果。断点位于第二感测线段621b上，能够避免新增可视角度，从而能够在提升感测效果的同时，避免增大可视化风险。
示例性地，参见图10，设置有第一断点的第二感测线段621b的断面的上边沿TL在基底层61上的正投影和与第一断点对应的第二感测线段621b在基底层61上的正投影垂直，上边沿TL即为断面边沿中远离基底层的边沿。具体的，应该在工艺水平能够实现的情况下，尽可能地使设置有第一断点的第二感测线段621b的断面的上边沿TL在基底层61上的正投影和与第一断点对应的第二感测线段621b在基底层61上的正投影相垂直，而由于工艺水平限制，两者之间的夹角在85°～95°的数值区间内时，即可视为二者垂直。第二感测线段621b的断面的上边沿TL与下边沿BL平行，下边沿BL和第二感测线段621b在基底层61上的正投影也垂直。受制于现有的工艺水平，在形成断点时，尖角线端(金属线的断面边沿在基底层61上的正投影与金属线的延伸方向的夹角为锐角)处的尖角会形成圆角(金属线的断面边沿在基底层61上的正投影为弧线)，导致实际形成的线端形状与设计的线端形状存在较大差异。而直角线端(金属线的断面边沿在基底层61上的正投影与金属线的延伸方向的夹角为直角)处的直角经过实际的刻蚀工艺形成的线端形状与设计的线端形状差异较小，更符合工艺要求。同时，尖角线端处容易出现尖端放电，而将线段设置为直角线端能够防止尖端放电的发生，避免对触控显示装置造成损坏，保证触控显示装置的使用寿命。
示例性地，每个感测电极62和与该感测电极62耦接的至少一条有效触 控走线63异层设置，触控层组还包括设置于感测电极62和有效触控走线63之间的绝缘层65，每个耦接部631通过绝缘层65上的至少一个过孔h与感测电极62耦接。参见图11，每个感测电极62上设置有一条与其耦接的有效触控走线63，该有效触控走线63的耦接部631通过两个过孔h与感测电极62的两条感测主线621耦接。具体的，不对感测电极62和有效触控走线63的相对位置做过多限制，例如，参见图11，可以是感测电极62相对于有效触控走线63更靠近基底层61，又例如，参见图12，也可以是有效触控走线63相对于感测电极62更靠近基底层61，使得感测电极62远离显示面板中控制图像显示的驱动电路，从而避免感测电极62受到其他电信号的干扰，影响感测效果。感测电极62和有效触控走线63不同层设置，同时在感测电极62和有效触控走线63之间设置有绝缘层65，能够防止在制备工艺过程中感测电极62所包括的多条第三感测线段622和不与该感测电极62耦接的有效触控走线63相连接。
示例性地，绝缘层65的材料例如可以是氮化硅、氧化硅或氮氧化硅中的至少一种，对此不做限制。
以感测电极62相对于有效触控走线63更靠近基底层61为例，继续参见图11，每个耦接部631通过绝缘层65上的多个过孔h与感测电极62耦接。由于过孔处电阻较大，在感测电极62和有效触控走线63通过绝缘层65上的多个过孔h实现耦接情况下，多个过孔的连接关系为并联，因而当过孔数量增加时，过孔处的总电阻会减小，通过多个过孔进行耦接能够保证感测电极62和有效触控走线63有更好的导通性，且提高了连接可靠性。
又示例地，参见图13，每个感测电极62和与感测电极62耦接的至少一条有效触控走线63同层设置，每个耦接部631通过架桥的方式与感测电极62耦接，架桥与感测电极62之间设置有绝缘层65。即有效触控走线63和感测电极62均设置在基底层61上，由基底层61承载。有效触控走线63和感测电极62可以采用同种材料，在同一工艺步骤中形成。此处，可以是有效触控走线63和感测电极62相对于架桥靠近基底层61，也可以是架桥相对于有效触控走线63和感测电极62靠近基底层61。将有效触控走线63和感测电极62设置在同一层，可以减少感测电极62和有效触控走线63因位于不同层存在高度差引起的反光强度不同而导致的可视化。
为了便于描述，以下以有效触控走线63和感测电极62不同层设置为例，继续对本公开的内容进行说明。
示例性地，参见图14，至少一个(例如，可以是每个)感测电极62中， 相邻两条感测主线621之间通过至少一个连接部64连接，每个连接部64由至少两条第三感测线段622连接形成。感测电极62中的多条感测主线621相互独立，与感测电极62连接的具有自由线端的多条第三感测线段622只能增大单条感测主线621的感测面积，而感测电极62的感测面积由与有效触控走线63耦接的多条感测主线621所决定，感测电极62中不与有效触控走线63耦接的感测主线621并不能起到触摸感测的作用。因而要增大感测电极62的感测面积，需要使感测电极62中的多条感测主线621耦接，这样，只要有一条感测主线621或者与该感测主线621相连接的一条第三感测线段622和有效触控走线63耦接，感测电极62中相连接的多条感测主线621均可用于实现触摸感测。因此可通过多条第三感测线段622实现感测电极62中相互独立的多条感测主线621的连接，连接相邻两条感测主线621的多条第三感测线段622形成一个连接部64，相邻两条感测主线621之间可以设置多个连接部64，从而使感测电极62内部的多条感测主线621有更好的导通性，且可以提高连接可靠性。例如，参见图14，通过设置在相邻两条感测主线621之间的三条或四条第三感测线段622将这两条感测主线621连接起来，相邻两条感测主线621之间设置有两个连接部64。
示例性地，参见图14，相邻两列的至少一个连接部64在第二方向上的位置错开，列的方向平行于第一方向。感测主线621的延伸方向平行于第一方向，相应的，用于实现一条感测主线621与其他感测主线621耦接的多个连接部64也沿第一方向排列，一列连接部64即为设置两条感测主线621之间的多个连接部64，类似的，一行连接部64即为沿第二方向排列的多个连接部64。为了避免连接部64集中分布导致的可视化风险提升，需要使连接部64尽可能地均匀分布在感测电极62所限定的范围内，因而沿第一方向排列、与同一条感测主线621耦接且位于感测主线621两侧的两个连接部64之间间隔有至少一条第一感测线段621a，同时，相邻两列的至少一个连接部64在第二方向上的位置错开，即同一行的多个连接部64中，相邻两个连接部64之间间隔有至少两条感测主线621。具体的，沿第二方向相邻排列的两条感测主线621之间设置有至少两个连接部64，至少两个连接部64沿第一方向等间距分布，相邻的两个连接部64之间设置有至少四条第一感测线段621a。例如，参见图14，沿X方向相邻排列的两条感测主线621之间设置四个连接部64，四个连接部64沿Y方向等间距分布，相邻的两个连接部64之间设置有四条第一感测线段621a。沿Y方向排列、与同一条感测主线621耦接且位于感测主线621两侧的两个连接部64之间设置有至少一条第一感测线段621a，同一行 中相邻两个连接部64之间间隔有两条感测主线621。上述设置能够保证感测电极62中的多条感测主线621实现可靠电连接，具有最大的感测面积及触控感应量，同时能够保证连接部64在感测电极62所限定范围内均匀分布，从而将连接部64的可视化风险降到最低，最大程度地保障显示效果。
示例性地，参见图15，触控层组还包括与多条所示有效触控走线63同层设置的至少一条虚拟触控走线66，至少一条()虚拟触控走线66的延伸方向平行于第一方向，且至少一条虚拟触控走线66沿第二方向排列。虚拟触控走线66与有效触控走线63的形状大致相同，至少一个(例如，可以是每个)感测电极62对应的各条有效触控走线63和各条虚拟触控走线66沿第二方向等间距分布。即在该层中，沿第二方向相邻的任意两条金属线之间的间距均相等，相邻的两条金属线可以一条为有效触控走线63，一条为虚拟触控走线66；也可以为两条有效触控走线63，还可以为两条虚拟触控走线66。在每个感测电极62所限定的范围内设置有多条有效触控走线63，多条有效触控走线63可以集中设置，也可以分散设置在感测电极62所限定的范围内，有效触控走线63的分布范围小于感测电极62所限定的范围。当多条有效触控走线63集中设置时，设置有效触控走线63的区域会对光线进行反射，而同一层中未设置有效触控走线63的区域不会对光线进行反射，从而产生显示mura，对触控显示装置的显示效果造成不良影响。而当多条有效触控走线63分散设置时，有效触控走线63之间的间距较大，也存在较大的反光强度差异，具有较高的可视化风险。因此参见图15，可与多条有效触控走线63同层设置多条虚拟触控走线66，每条虚拟触控走线66穿过沿Y方向排布的多个感测电极62。虚拟触控走线66不用于传输感测信号，因而在一些示例中，虚拟触控走线66不与任何感测电极62耦接。每条虚拟触控走线66的形状与有效触控走线63大致相同，也即虚拟触控走线66的形状与有效触控走线63相似，这样能够保证虚拟触控走线66与有效触控走线63的可视角度相同，增设虚拟触控走线66不会出现新增可视角度，避免提升可视化风险。多条虚拟触控走线66和多条有效触控走线63同层设置，多条虚拟触控走线66和多条有效触控走线63等间距分布，即对任意一条有效触控走线63而言，沿第二方向与其相邻的能够使得在感测电极62所限定的范围内金属线(即多条虚拟触控走线66和多条有效触控走线63)的数量增多，密度增大，金属线间的间距减小，从而降低因间距过大或金属线集中设置而导致的显示mura，提升显示效果。
示例性地，参见图16，在触控层组中，至少一个(例如，可以是每个)感测电极62具有一个第一区域601，位于第一区域601的各条有效触控走线 63与位于第一区域601的多条感测主线621交替排布。即在第一区域601中，任意相邻的两条有效触控走线63之间设置的感测主线621的条数相等。例如，参见图16，第一区域601为感测电极62所限定的区域，即穿过该感测电极62的有效触控走线63在整个感测电极62上都分布，且有效触控走线63在X方向上任意相邻的两条有效触控走线63之间间隔的感测主线621的数量相等，均为x条，x≥1，具体的，x＝1。
又例如，参见图17，第一区域601为感测电极62所限定的区域中的部分区域。在此情况下，至少一个(例如，可以是每个)感测电极62还具有两个第二区域602，位于第二区域602的至少一条虚拟触控走线66与位于第一区域601的多条感测主线621交替排布。即在第二区域602中，任意相邻的两条虚拟触控走线66之间设置的感测主线621的条数均相等，且与任意相邻的两条有效触控走线63之间设置的感测主线621的条数一致。两个第二区域602分别位于第一区域601沿第二方向上的两侧。此时，有效触控走线63仅在第一区域601排布，在第二区域602不设置，同样的，虚拟触控走线66仅在第二区域602排布，在第一区域601不设置，在X方向上相邻的任意两条金属线(即虚拟触控走线66和/或有效触控走线63)之间间隔的感测主线621的数量相等，均为一条。多条有效触控走线63在感测电极62所限定的区域内尽可能居中设置，使得距有效触控走线63较远的感测电极62边界处的电容变化量更大，从而实现更好的感测效果。
示例性地，至少一条(例如，可以是每条)虚拟触控走线66包括至少一条(例如，可以是多条)虚拟触控走线段661，每条虚拟触控走线段661与一个感测电极62耦接。例如，参见图18，穿过多个感测电极62的虚拟触控走线66被多个断点划分为多条虚拟触控走线段661，每条虚拟触控走线段661与其穿过的感测电极62耦接。对虚拟触控走线段661与感测电极62的具体耦接方式不做过多限制，可以通过至少一个(例如，可以是多个)过孔耦接，当然也可以是其他方式。在此情况下，虚拟触控走线段661相当于感测电极62的一部分。虚拟触控走线段661与感测电极62耦接，可以增加感测电极62的面积，提升触控时的感应量。同时，由于每条虚拟触控走线段661与一个感测电极62耦接，因此即使该虚拟触控走线段661和与其耦接的感测电极62在基底层61上的正投影有重叠区域，该虚拟触控走线段661和感测电极62之间也不会产生耦合电容。
示例性地，多条有效触控走线63的长度可以大致相同，也可以不同。例如，参见图4，每条有效触控走线63均穿过显示区中沿Y方向排列的一列感 测电极62，多条有效触控走线63的长度大致相同，其等效电阻值也大致相等，对感测信号的电位产生的影响也基本一致，从而能够等效为消除了走线长度会对感测信号的产生不良影响，有利于提高感测结果的准确性。在每个感测电极62限定的范围内设置的有效触控走线63的条数不小于该列感测电极62的个数，从而保证每个感测电极62能与至少一条有效触控走线63耦接。此外，在每个感测电极62限定的范围内还可以包括与有效触控走线63同层设置至少一条(例如，可以是一条)虚拟触控走线66，用于降低该层金属线的可视化风险。每条虚拟触控走线66划分为多条与感测电极62耦接的虚拟触控走线66段，增加感测电极62的面积。
又例如，参见图19，多条有效触控走线63的长度不同，沿X方向排列的多条有效触控走线63沿Y方向穿过的感测电极62的个数不同，每条有效触控走线63的一端位于显示区的边缘区域，另一端设置在与其耦接的感测电极62限定的范围内。同时，还可以包括与有效触控走线63同层设置至少一条(例如，可以是多条)虚拟触控走线66，多条虚拟触控走线66的长度不同，每条虚拟触控走线66划分为多条与感测电极62耦接的虚拟触控走线66段，能够增加感测电极62的面积。在每个感测电极62限定的范围内有效触控走线63的条数与虚拟触控走线66段的条数之和不小于该列感测电极62的个数，从而降低该层金属线的可视化风险。
示例性地，至少一条(例如，可以是每条)虚拟触控走线66由多条第一触控线段661a和多条第二触控线段661b交替连接形成，至少一条(例如，可以是每条)第一触控线段661a平行于第一方向，至少一条(例如，可以是每条)第二触控线段661b倾斜于第一方向。例如，参见图20，第一触控线段661a为沿Y方向延伸的直线段，第二触控线段661b为不沿Y方向延伸的斜向线段，第二触控线段661b的延伸方向与第一触控线段661a的延伸方向之间存在夹角，该夹角为钝角。当然，该夹角也可以为锐角，对此不做限制。
示例性地，在触控层组中，多条第二触控线段661b包括多条第三斜向线段L3和多条第四斜向线段L4，多条第三斜向线段L3和多条第四斜向线段L4沿第一方向交替排列。第三斜向线段L3平行于第一斜向线段L1，第四斜向线段L4平行于第二斜向线段L2，第一感测电极62A和第二感测电极62B中，同一延伸方向上的两条虚拟触控走线段661之间的多个断点中，一部分断点位于第三斜向线段L3上，另一部分断点位于第四斜向线段L4上。具体的，参见图20，倾斜于第一方向的第二触控线段661b可划分为第三斜向线段L3和第四斜向线段L4，第三斜向线段L3和第四斜向线段L4的倾斜方向即 延伸方向不同，第三斜向线段L3平行于第一斜向线段L1，第四斜向线段L4平行于第二斜向线段L2。除虚拟触控走线段661的线端处以外，每条第一触控线段661a的一端与至少一条(例如，可以是一条)第三斜向线段L3连接，另一端与至少一条(例如，可以是一条)第四斜向线段L4连接。虚拟触控走线段661由多个断点划分虚拟触控走线66得到，由于第三斜向线段L3平行于第一斜向线段L1，第四斜向线段L4平行于第二斜向线段L2，因而第三斜向线段L3和第一斜向线段L1的可视角度相同，第四斜向线段L4和第二斜向线段L2的可视角度相同将划分虚拟触控走线66的多个断点分散地设置在第三斜向线段L3和第四斜向线段L4上，在一个可视角度下只有部分断点存在可视化风险，其余断点并不会对该可视角度下的显示效果造成影响。上述设置能够在增大感测电极62的面积，提升触控感应量的同时，避免提高反光强度差异所导致的可视化风险，有利于显示效果的提升。
示例性地，在触控层组中，多条虚拟触控走线段661之间的多个断点交替位于第三斜向线段L3和第四斜向线段L4上。参见图20，与感测主线621断点设置方式类似，该设置也能够使得在一个可视角度下存在可视化风险的断点数量较少，同时多个断点均匀分散，能够进一步降低可视化风险，有利于显示效果的提升。
示例性地，设置有断点的第二触控线段661b的断面的上边沿和第二触控线段661b的延伸方向垂直。该设置与感测主线621断点的设置方式类似，同样具有上述效果，在此不再赘述。
基于上述，在触控层组应用于触控显示装置中的情况下，有效触控走线63和感测电极62均位于像素界定区域。即每条有效触控走线63、以及形成感测电极62的多条第一感测线段621a、多条第二感测线段621b和多条第三感测线段622均设置在相邻两个亚像素区101a之间的像素界定区域101b内。例如，参见图21，触控层组中的感测电极62和穿过该感测电极62的有效触控走线63在基底层61上的正投影构成多个网眼，一个亚像素区与一个网眼对应。上述设置能够在提升感测效果、避免感测电极62及有效触控走线63产生显示mura的前提下，避免不透光的多条金属线对亚像素区101a的出光造成遮挡。
不同颜色亚像素的发光效率和使用寿命等均存在差异，因此不同颜色亚像素的形状和大小也会存在差异。例如，可以将发光效率较低的亚像素做得大一些，将发光效率较高的亚像素做得小一些，以平衡不同颜色亚像素的发光情况，从而完成正常显示。示例性地，参见图21，多个亚像素101a包括 红色亚像素R、绿色亚像素G以及蓝色亚像素B时，由于绿色亚像素G的发光效率较高，蓝色亚像素B的发光效率较低，红色亚像素R的发光效率居中，因此亚像素的大小为蓝色亚像素B＞红色亚像素R＞绿色亚像素G。相应的，亚像素区101a的形状也可以如图22所示，部分为六边形，部分为五边形，红色亚像素R和蓝色亚像素B设置在六边形的亚像素区101a中，绿色亚像素G设置在五边形的亚像素区101a中。参见图22，一个红色亚像素R、一个绿色亚像素G以及一个蓝色亚像素B构成一个像素103，并且两个像素103共用一个红色亚像素R。
在此情况下，上述的触控层组中还可以包括至少一条(例如，可以是多条)第四感测线段623，每条第四感测线段623垂直于与其连接的一条第一感测线段621a。示例性地，参见图20和图21，在一个感测电极62中，多条感测主线621可分为第一感测主线621A和第二感测主线621B。其中，第一感测主线621A的每条第一感测线段621a均与一条第四感测线段623连接，且与一条第一感测主线621A连接的多条第四感测线段623沿第一方向交替设置于第一感测主线621A的两侧；第二感测主线621B的多条第一感测线段621a中仅有部分连接有第四感测线段623，且与一条第二感测主线621B连接的多条第四感测线段623均位于该第二感测主线621B的同一侧。包括多条第四感测线段623的感测电极62和穿过该感测电极62的有效触控走线63在基底层61上的正投影构成多个网眼，一个亚像素区与一个网眼对应。上述设置能够在不对亚像素区101a的出光造成遮挡的前提下，进一步增大感测电极62的面积，提升触控感应量。
示例性地，在触控显示装置中，沿第二方向相邻的两条感测主线621之间间隔m个亚像素区；m≥1，m为正整数。例如，参见图21，m＝2。有效触控走线63和感测主线621沿X方向交替设置，当两条感测主线621之间间隔m个亚像素区时，一方面，若两条感测主线621之间间隔的亚像素区过少，例如仅间隔一个亚像素区时，为了避免感测电极62与有效触控走线63在基底层61上正投影重叠过多，感测主线621只能包括多条相互独立的第二感测金属线段，要实现感测电极62与有效触控走线63的耦接需要设置大量过孔，增大了工艺难度，同时连接效果难以保证，因此m≥1；另一方面，m≥1时，结合第三感测线的避让设计，能够最大程度减小感测电极62与有效触控走线63在基底层61上正投影的重叠面积，使得感测面积尽可能大，同时能够使得有效触控走线63和感测主线621均匀分布，在优化布线方式的前提下，降低出现显示mura的风险。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
