具体实施方式
下面将结合附图，对本公开一些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公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“电连接”和“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“点连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。这里所公开的实施例并不必然限制于本文内 容。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
本文中“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
如本文所使用的那样，“近似”或“大致”包括所阐述的值以及处于特定值的可接受偏差范围内的平均值，其中所述可接受偏差范围如由本领域普通技术人员考虑到正在讨论的测量以及与特定量的测量相关的误差(即，测量系统的局限性)所确定。
本文参照作为理想化示例性附图的剖视图和/或平面图描述了示例性实施方式。在附图中，为了清楚，放大了层和区域的厚度。因此，可设想到由于例如制造技术和/或公差引起的相对于附图的形状的变动。因此，示例性实施方式不应解释为局限于本文示出的区域的形状，而是包括因例如制造而引起的形状偏差。例如，示为矩形的蚀刻区域通常将具有弯曲的特征。因此，附图中所示的区域本质上是示意性的，且它们的形状并非旨在示出设备的区域的实际形状，并且并非旨在限制示例性实施方式的范围。
随着AMOLED(Active Matrix Organic Light-Emitting Diode，有源矩阵有机发光二极管)显示装置的迅速发展，全面屏、窄边框、高分辨率、卷曲穿戴、折叠等成为未来AMOLED的重要发展方向。
其中，直接在OLED(Organic Light-Emitting Diode，有机发光二极管)显示面板的封装层上制作触控结构的技术，能够制备更轻更薄的触控面板，且该技术可以应用于折叠及卷曲的OLED显示装置中。
基于降低电阻和提高触控灵敏性等方面的考虑，触控结构中的触控电极采用具有电阻小、厚度小和反应速度快等优点的金属网格。相关技术中，直接在显示面板的封装层上制作的触控结构包括两种类型，柔性多层覆盖表面 式(Flexible Metal Layer On Cell，FMLOC)和柔性单层覆盖表面式(Flexible Single Layer On Cell，FSLOC)，其中，FSLOC相较于FMLOC更便于产品减薄。
如图4所示，图4为形成金属网格的金属导线的截面示意图，在暗态强光照射下，照射到金属导线表面01的光线会被显示面板贴附的偏光片遮挡，无法进入人眼，而对于照射到金属导线侧壁02的光线，偏光片无法遮挡，会进入人眼，进而有金属导线和无金属导线的区域会形成光线差异，导致人眼看到亮暗图案。
基于此，如图11所示，本公开的一些实施例提供一种显示面板900，包括显示基板200，以及位于显示基板200出光侧的封装层250，以及位于封装层250背离显示基板200一侧的触控结构1000。显示面板900应用于触控显示装置，如图12和图13所示。触控显示装置可以为电致发光显示装置或光致发光显示装置。在该显示装置为电致发光显示装置的情况下，电致发光显示装置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)或液晶显示装置(Liquid Crystal Display，LCD)或电泳显示(Electrophoretic Displays，EPD，EPD)。在该触控显示装置为光致发光显示装置的情况下，光致发光显示装置可以为量子点光致发光显示装置。
本公开的示例性实施例中以OLED显示装置进行说明，但应当认为并不限于OLED显示装置。在一些实施例中，如图12和图13所示，触控显示装置的主要结构包括依次设置的显示面板900、触控结构1000、抗反射结构例如偏光片500、第一光学胶(Optically Clear Adhesive，简称OCA)层600和盖板300。在一些实施例中，抗反射结构可以包括彩色滤光片和黑矩阵。抗反射结构的位置并不限定于上述描述，可以位于封装层和显示基板之间，或其它可实现的位置。
其中，显示面板900包括显示基板200和用于封装显示基板200的封装层250。此处，封装层250可以为封装薄膜，也可以为封装基板。
在一些实施例中，如图12所示，显示面板900的触控结构1000直接设置在封装层250上，这样可以将显示基板200视作触控结构1000的衬底基板，这种结构有利于实现显示装置的轻薄化。
在一些实施例中，封装层250可以包括第一无机封装层、第一有机封装层和第二无机封装层，也可以为至少一层有机层和至少一层无机层的堆叠结构。在一些实施例中，抗反射结构可以形成在封装层250中，起到抗反射作用，同时可以进一步降低显示装置的厚度。
在另一些实施例中，如图13所示，显示面板900的触控结构1000设置在衬底基板910上，衬底基板910通过第二光学胶层920贴附在封装层250上。衬底基板910的材料例如可以是聚对苯二甲酸乙二酯(Polyethylene terephthalate，简称PET)、聚酰亚胺(Polyimide，简称PI)、环烯烃聚合物(Cyclo Olefin Polymer，简称COP)等。
如图10、图11、图12和图13所示，上述的显示基板200的每个子像素211包括设置在衬底210上的发光器件和驱动电路，驱动电路包括多个薄膜晶体管270。发光器件包括阳极222、发光层223以及阴极224，阳极222和驱动电路的多个薄膜晶体管270中作为驱动晶体管的薄膜晶体管270的漏极电连接。
在一些实施例中，阳极222和驱动电路的多个薄膜晶体管270中作为驱动晶体管的薄膜晶体管270的漏极电连接时，还通过一个转接电极进行电连接，转接电极位于漏极所在膜层和阳极所在膜层之间。
显示基板200还包括像素界定层225，像素界定层225包括多个出光口225A，一个发光器件对应一个出光口225A设置。
在一些实施例中，显示功能层220包括发光层223。在另一些实施例中，显示功能层220除包括发光层223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12和图13所示，显示基板200还包括设置在薄膜晶体管270和阳极222之间的至少一层平坦层230。在一些实施例中，平坦层230上还包括至少一层钝化层。
当触控显示装置为电致发光显示装置时，触控显示装置可以是顶发射型显示装置，在此情况下，靠近衬底210的阳极222呈不透明，远离衬底210的阴极224呈透明或半透明；触控显示装置也可以是底发射型显示装置，在此情况下，靠近衬底210的阳极222呈透明或半透明，远离衬底210的阴极224呈不透明；触控显示装置也可以为双面发光型显示装置，在此情况下，靠近衬底210的阳极222和远离衬底210的阴极224均呈透明或半透明。
参见图1A-图1D、图2A-图2D、图3A-图3D所示，本公开实施例提供一种触控结构1000，包括：
金属网格100，金属网格100包括多条金属导线110；
其中，金属网格100具有多个开口单元120，每一开口单元120包括至少三个开口100A，每个开口100A由多条金属导线110围成，且围成每个开口100A的多条金属导线110具有至少三个不同的延伸方向；用于划分开口单元120内开口的至少一条金属导线110，与围成开口单元120外边界的各金属导线100的延伸方向不同。具体的，例如，结合图1B或图1C所示，围成开口单元120外边界的各金属导线100的延伸方向为横向或斜向的，用于划分开口单元120内开口100A的多条金属导线110包括竖向的金属导线110，该竖向的金属导线110A与围成开口单元120外边界的各金属导线100的延伸方向不同；又例如，结合图2B或图2C所示，围成开口单元120外边界的各金属导线100的延伸方向为斜向的，用于划分开口单元120内开口100A的多条金属导线110包括竖向的金属导线110，该竖向的金属导线110A与围成开口单元120外边界的各金属导线100的延伸方向不同；又例如，结合图3B-图3D所示，围成开口单元120外边界的各金属导线100的延伸方向为横向或竖向的，用于划分开口单元120内开口100A的多条金属导线110包括斜向的金属导线110，该斜向的金属导线110A与围成开口单元120外边界的各金属导线 100的延伸方向不同。
触控结构1000的触控区域可以与显示基板200中的显示区域AA(又称有效显示区，英文名称为Active Area)重叠。
本公开实施例中，在围成每个开口的多条金属导线具有至少三个不同的延伸方向，用于划分开口单元120内开口的至少一条金属导线110，与围成开口单元120外边界的各金属导线100的延伸方向不同的情况下，一方向上的入射光经过开口反射，得到的反射光的方向较多，每个反射方向上的光线较为分散，达到类散射的效果，反射亮度下降，降低人眼感知的反射差异程度。另外，增加围成每个开口的金属导线数量，在触控电极(Tx和Rx)分界处，因为金属导线数量和方向变多，可以进行更多选择的断口(cut)，从而把分界处人眼感知的反射差异程度(touch mura)降到最低。
因此，通过将开口100A的形状设置为围成每个开口100A的多条金属导线110具有至少三个不同的延伸方向，用于划分开口单元120内开口的至少一条金属导线110，与围成开口单元120外边界的各金属导线100的延伸方向不同，这样能够增加金属网格100中金属导线110的延伸方向，使得金属网格100整体的反射光方向增加，达到或接近光线散射的效果，消除或减轻金属网格100在同一方向上形成连续反射光的现象，降低人眼感知的反射差异程度，提高显示效果。
与此之外，外界光线在射向显示面板时，靠近表层的触控结构1000的金属网格100，针对外界光线的反射是造成Mura现象(亮度显示不均匀，显示各种痕迹的现象)的主要原因。本公开的一些实施例通过将上述开口100A的形状设置为围成每个开口100A的多条金属导线110具有至少三个不同的延伸方向，实现反射光的散射效果，还能够消除或减轻显示面板900的Mura现象，提高显示面板900的显示效果。
在一种可能的实施方式中，围成开口单元120外边界的金属导线110数量，大于开口单元120内部的金属导线110数量。具体的，例如，结合图1B和图1C所示，围成开口单元120外边界的金属导线110包括：两条a1，两条 a2，两条a3，共6条金属导线110，开口单元120内部的金属导线110包括：两条a4，两条a5共4条金属导线110，围成开口单元120外边界的金属导线110数量，大于开口单元120内部的金属导线110数量；又例如，结合图2B和图2C所示，围成开口单元120外边界的金属导线110包括：四条a6，两条a7，四条a8，两条a9共12条金属导线110，开口单元120内部的金属导线110包括：一条a10，一条a11共2条金属导线110，围成开口单元120外边界的金属导线110数量，大于开口单元120内部的金属导线110数量；又例如，结合图3B-图3D所示，围成开口单元120外边界的金属导线110包括：两条a12，两条a13共4条金属导线110，开口单元120内部的金属导线110包括：一条a14，一条或两条a15，至多3条金属导线110，围成开口单元120外边界的金属导线110数量，大于开口单元120内部的金属导线110数量。
在一种可能的实施方式中，围成开口单元120外边界的金属导线110中，至少包括一对延伸方向相同的金属导线110。具体的，例如，结合图1B和图1C所示，围成开口单元120外边界的金属导线110中，延伸方向相同有两条a1，两条a2，两条a3，共3对的金属导线110；又例如，结合图2B和图2C所示，围成开口单元120外边界的金属导线110中，延伸方向相同有四条a6，两条a7，四条a8，两条a,9，共6对的金属导线110；又例如，结合图3B-图3D所示，围成开口单元120外边界的金属导线110中，延伸方向相同有两条a12，两条a13，共2对的金属导线110。
在一种可能的实施方式中，图1A-图1D所示，开口单元120外边界为平行六边形。本公开实施例中，开口单元120外边界为平行六边形，有利于多个开口单元120相互无间隙拼接，形成紧密排列的结构，也形成紧密排列的多个开口100A，由于开口100A通常与子像素一一对应，如此，也可以实现使子像素紧密排列，进而在有限的区域实现排布较多的子像素，提升显示装置的分辨率。
在一种可能的实施方式中，图1B和图1C所示，围成开口单元120外边界的金属导线110包括：相对且平行设置的两条第一金属导线a1，相对且平 行设置的两条第二金属导线a2，相对且平行设置的两条第三金属导线a3，其中一第二金属导线a2连接一第一金属导线a1与一第三金属导线a3，另一第二金属导线a2连接另一第一金属导线a1与另一第三金属导线a3。具体的，例如，图1B中，左侧的第二金属导线a2连接上方的第一金属导线a1与左下侧的第三金属导线a3，右侧的第二金属导线a2连接下方第一金属导线a1与右上侧的第三金属导线a3。
在一种可能的实施方式中，图1B和图1C所示，第三金属导线a3的长度L3大于第一金属导线a1的长度L1，第一金属导线a1的长度L1大于第二金属导线a2的长度L2。
在一种可能的实施方式中，图1B和图1C所示，第二金属导线a2与相连的第三金属导线a3垂直。
在一种可能的实施方式中，图1B和图1C所示，开口单元120内，第一金属导线a1与相连的第二金属导线a2形成的第一夹角β1，与第一金属导线a1与相连的第三金属导线a3形成的第二夹角β2相同。
在一种可能的实施方式中，图1B和图1C所示，开口单元120内，第一金属导线a1与相连的第二金属导线a2形成的第一夹角β1范围为120°～150°。在一种可能的实施方式中，第一金属导线a1与相连的第二金属导线a2形成的夹角β1为135°。本公开实施例中，开口单元120内，第一金属导线a1与相连的第二金属导线a2形成的夹角β1范围为120°～150°，在具体制作时，角度相对易于制作，有利于简化触控结构的制作工艺。
此外，当第一金属导线a1与相连的第二金属导线a2形成的夹角β1为135°时，若设定第一金属导线a1所在方向为0°所在方向，则第二金属导线a2为以45°倾斜方向排布，第四金属导线a4为90°竖向排布，第三金属导线a3以135°倾斜方向排布，这种错位排布保证有利于触控电极(Tx和Rx)分界处的开口弯折设计(如图5所示虚粗线和实粗线所示)，Tx和Rx分界为45°和135°对角方向时，更有利于与非边界处的开口设计搭配设计，从开口设计的角度规避暗态反射MURA，降低人眼感知的反射差异程度。
在一种可能的实施方式中，图1B和图1C所示，开口单元120内包括：分别由第一金属导线a1中点且沿垂直于第一金属导线a1延伸的两条第四金属导线a4，以及沿平行于第二金属导线a2方向延伸、分别连接第四金属导线a4另一端与第三金属导线a3中点的两条第五金属导线a5。如此，可以使开口单元120形成两个五边形的开口100A，以及一个八边形的开口100A，形成面积不同的三个开口100A，以对应设置三个子像素时，使不同子像素的面积不同，例如，使八边形开口100A设置蓝色子像素，两个五边形的开口100A分别设置红色子像素与绿色子像素，由于蓝色子像素所使用材料限制，使蓝色子像素寿命较短，发光亮度较低，通过使蓝色子像素设置较大的面积，有利于使显示装置不同出光颜色的子像素亮度和寿命达到均衡。另外，人眼对于色彩敏感度不同，人眼对于色彩敏感度具体为：绿色＞红色＞蓝色，由于此原因，通过蓝色子像素B的面积大于所述红色子像素R的面积，红色子像素R的面积大于绿色子像素G的面积的设计，能够实现人眼对各色光线的感受平衡，减少子像素冗余，提升开口率和分辨率。
在一种可能的实施方式中，图1B和图1C所示，第四金属导线a4的长度为与第一金属导线a1长度L1的二分之一；第五金属导线a5的长度与第二金属导线a2的长度L2相等。
在一种可能的实施方式中，图2B和图2C所示，开口单元120外边界为十字形。本公开实施例中，开口单元120外边界为十字形，有利于多个开口单元120相互无间隙拼接，形成紧密排列的结构，也形成紧密排列的多个开口100A，由于开口100A通常与子像素一一对应，如此，也可以实现使子像素紧密排列，进而在有限的区域实现排布较多的子像素，提升显示装置的分辨率。
在一种可能的实施方式中，图2B和图2C所示，开口单元120包括：两个相对且沿第一方向X1向相远方向延伸的第一外凸部b1，以及两个相对且沿第二方向X2向相远方向延伸的第二外凸部b2；第一方向X1与第二方向X2垂直。
在一种可能的实施方式中，第一方向X1可以为与重复单元Z进行排列时形成的竖向呈45°的方向，第二方向X2可以为与重复单元Z进行排列时形成的行向呈45°的方向。
在一种可能的实施方式中，图2B和图2C所示，第一外凸部b1的外边界包括：两条沿第一方向X1延伸的第六金属导线a6，以及连接两条第六金属导线a6且沿第二方向X2延伸的第七金属导线a7；第二外凸部b2的外边界包括：两条沿第二方向X2延伸的第八金属导线a8，以及连接两条第八金属导线a8且沿第一方向X1延伸的第九金属导线a9；第一外凸部b1的第六金属导线a6与相邻的第二外凸部b2的第八金属导线a8相交于第一节点A1。
在一种可能的实施方式中，图2B和图2C所示，第六金属导线a6的长度大于第七金属导线a7的长度，第八金属导线s8的长度大于第九金属导线a9的长度。
在一种可能的实施方式中，图2B和图2C所示，开口单元120内部包括：连接相邻第一外凸部b1与第二外凸部b2的两个不相邻第一节点A1的第十金属导线a10，以及连接第十金属导线a10中点与第十金属导线a10一侧的一第一节点A1的第十一金属导线a11。
在一种可能的实施方式中，参见图1A-图1D、图2A-图2D所示，开口单元120包括：第一子开口单元1201与第二子开口单元1202，第一子开口单元1201与第二子开口单元1202为镜像对称结构，两个第一子开口单元1201与两个第二子开口单元1202围成一重复单元Z；重复单元Z内，两个第一子开口单元1201通过复用一开口连接，形成第一组合体；两个第二子开口单元1202通过复用一开口连接，形成第二组合体；第一组合体通过外边界的相邻两个金属导线，分别与两个不同第二子开口单元1202的金属导线110进行复用形成重复单元Z。
在一种可能的实施方式中，重复单元Z中，复用的开口内部的金属导线可以无需设置，如图1D或图2D中开口内的虚线所示位置。
在一种可能的实施方式中，参见图3A-图3D所示，开口单元120外边界 为矩形。本公开实施例中，开口单元120外边界为矩形，有利于多个开口单元120相互无间隙拼接，形成紧密排列的结构，也形成紧密排列的多个开口100A，由于开口100A通常与子像素一一对应，如此，也可以实现使子像素紧密排列，进而在有限的区域实现排布较多的子像素，提升显示装置的分辨率。
在一种可能的实施方式中，参见图3B-图3D所示，围成开口单元120外边界的金属导线110包括：沿第三方向X3延伸且相对设置的两条第十二金属导线a12，以及沿第三方向X3延伸且相对设置的两条第十三金属导线a13，其中一第十三金属导线a13分别连接两第十二金属导线a12的一端，另一第十三金属导线a13分别连接两第十二金属导线a12的另一端；具体的，例如，左侧的第十三金属导线a13分别连接上下第十二金属导线a12的左端，右侧的第十三金属导线a13分别连接上下两第十二金属导线a12的右端；开口单元120内包括：由第十三金属导线a13上的一点向内延伸的第十四金属导线a14，以及连接相对两第十二金属导线a12的第十五金属导线a15，第十四金属导线a14的另一端连接于第十五金属导线a15上的一点；第十四金属导线a14、第十五金属导线a15中的至少一者既不平行于第三方向，也不平行于第四方向。
在一种可能的实施方式中，参见图3C所示，第十五金属导线a15为一直线段。
在一种可能的实施方式中，参见图3B和图3D所示，第十五金属导线a15包括两条延伸方向不同的子金属导线a150。
在一种可能的实施方式中，参见图3B和图3D所示，其中一子金属导线a150与第四方向X4的夹角为第三夹角β3，另一子金属导线与第四方向的夹角为第四夹角β4，第三夹角β3与第四夹角β4不相等。如此，以形成两条延伸方向不同的子金属导线，有利于增加反射光线的方向。
在一种可能的实施方式中，参见图3B和图3D所示，第三夹角β3的范围为10°～45°，第四夹角β4的范围为10°～45°。
示例性的，结合图3B-图3D所示，通过调整W1-W5的长度，实现R、G、 B三个子像素开口率的差异化，从而可以保证更好的显示质量。
在一些实施例中，金属导线110的材料包括铜Cu、银Ag、纳米碳或石墨烯中的至少一种。以金属导线110的材料包括银为例，银可以指的是银单质，也可以指纳米银、还可以是银的其他结构形态；另外，金属导线110的材料还可以是包括银元素的化合物，此处不做限定。
以金属导线110的材料包括铜和纳米碳为例，铜可以指的是铜单质，也可以指纳米铜、还可以是铜的其他结构形态；纳米碳可以指的碳纳米管、也可以指碳纳米纤维，还可以指纳米碳球等结构形态。金属导线110的材料可以包括上述任一种铜形式和上述任一种纳米碳形式的混合物。
在一些实施例中，如图6所示，触控结构可以包括多个触控电极410，每个触控电极410包括金属网格，且所述多个触控电极被配置为各自独立地连接至触控芯片。
多个触控电极410之间相互绝缘设置，且多个触控电极410排布在显示区域内。多个触控电极410的形状可以相同，触控电极410的形状可以为菱形或大致菱形，其中，“大致为菱形”是指，触控电极410的形状整体上呈菱形形状，但是并不局限为标准的菱形，例如触控电极410的边界允许是非直线形的(例如锯齿形)。
另外，触控电极410的形状不限于菱形或大致的菱形，还可以是矩形、长条形等。
触控电极410包括金属网格是指每个触控电极均采用金属网格结构，相比于采用ITO(Indium Tin Oxide，氧化铟锡)形成面状电极作为触控电极410，金属网格结构的触控电极410的电阻小、灵敏度较高，能够提高触控显示面板的触控灵敏度。且采用金属网格结构的触控电极410机械强度高，能减小触控显示面板的重量，在触控显示面板应用于显示装置中时，能够实现显示装置的轻薄化。
多个包括金属网格结构的触控电极410可以设置于同一金属层，即FSLOC结构，便于显示装置的轻薄化。
每个触控电极410均独立与触控芯片电连接，触控芯片向触控电极410提供电压，使得触控电极410可以独立地与地形成电容。后续通过感应多个电容的变化从而确定显示区域内的触控点位。
其中，触控电极410内的金属网格的金属导线可以与显示区域中多个子像素221的发光区221A之间的间隙正对设置，从而能够防止金属网格遮挡光线射出，确保显示装置的发光效率。
在一些实施例中，如图7所示，触控结构可以包括相互绝缘的多个驱动单元510和多个感应单元520；每个驱动单元510包括沿第三方向X3并列设置的多个驱动电极511，及电连接相邻两个驱动电极511的第一连接部512；每个感应单元520包括沿第四方向X4并列设置的多个感应电极521，及电连接相邻两个感应电极521的第二连接部522。第三方向X3和第四方向X4相交叉。具体的，第三方向X3可以为驱动电极511排列形成的行向，第三方向X3可以为驱动电极511排列形成的列向。
如图8和图9所示，触控结构包括依次叠置的第一金属层610、绝缘层620和第二金属层630，绝缘层620中设有多个过孔621。
示例性地，驱动电极511、第一连接部512和感应电极521位于第一金属层610和第二金属层630中的一者，第二连接部522位于第一金属层610和第二金属层630中的另一者，且第二连接部522通过过孔621电连接相邻两个感应电极521。
示例性地，驱动电极511、第二连接部522和感应电极521位于第一金属层610和第二金属层630中的一者，第一连接部512位于第一金属层610和第二金属层630中的另一者，且第一连接部512通过过孔621电连接相邻两个驱动电极511。
示例性地，驱动电极511、感应电极521、第一连接部512和第二连接部522包括金属网格。金属网格的开口形状和相关布置采用上述各实施例的设计，这样可以使得触控结构1000的反射光方向增加，降低每个反射光方向的反射光量，达到类散射的效果，使人眼无法感知反射光线，从而消除或减轻人眼 对感知的反射差异程度，提高显示效果。
如图7所示，第三方向X3与第四方向X4交叉设置，例如第三方向X3与第四方向X4可以相互垂直。例如，第三方向X3可以是触控显示装置的横向方向，第四方向X4可以是触控显示装置的纵向方向；或者，第三方向X3可以是触控显示装置的像素排列的行方向，第四方向X4可以是触控显示装置的像素排列的列方向。
需要说明的是，本公开的多个附图中仅以第三方向X3为横向方向，第四方向X4为纵向方向为例进行示意，在本公开中，通过将附图进行90度旋转所得到的技术方案亦在本公开的保护范围之内。
第一连接部512和第二连接部522至少在交叉位置处位于触控结构的不同金属层，即在交叉位置处，第一连接部512和第二连接部522中的一者位于第一金属层610，另一者位于第二金属层630，并且第一连接部512和第二连接部522在交叉位置处利用绝缘层620隔开，以防止第一连接部512和第二连接部522上传输的触控信号发生串扰。
示例性地，第一连接部512位于第一金属层610，位于第一金属层610且沿第一方向X相邻的两个驱动电极511直接通过第一连接部512相连；第二连接部522位于第二金属层630，位于第一金属层610且沿第二方向Y相邻的两个感应电极521分别通过绝缘层620中的不同过孔621与第二连接部522相连，从而实现两个感应电极521相连。
示例性地，如图7、图8和图9所示，第一连接部512位于第二金属层630，位于第一金属层610且沿第一方向X相邻的两个驱动电极511分别通过绝缘层620中的不同过孔621与第一连接部512相连，从而实现两个驱动电极511相连；第二连接部522位于第一金属层610，位于第一金属层610且沿第二方向Y相邻的两个感应电极521直接通过第二连接部522相连。
第二连接部522位于第一金属层610，位于第一金属层610且沿第二方向Y相邻的两个感应电极521直接通过第二连接部522相连；第一连接部512于第二金属层630，位于第一金属层610且沿第一方向X相邻的两个驱动电 极511分别通过绝缘层620中的不同过孔621与第一连接部512相连，从而实现两个驱动电极511相连。
需要说明的是，图8和图9中仅仅是以驱动电极511、第二连接部522和感应电极521位于第一金属层610，第一连接部512位于第二金属层630的情况的说明；其他情况下的电连接方式和结构图形可以采用相同的方式和原理毫无疑义地推导得出。另外，驱动电极511和感应电极521作不同的图案填充，是为了区分不同的电极，驱动电极511和感应电极521可以采用相同材料，采用相同的工艺制程形成。
在一些实施例中，驱动电极511和/或感应电极521的面积可以为9mm2～25mm2，即驱动电极511和感应电极521中至少一者的面积为9mm2～25mm2，可以是驱动电极511的面积为9mm2～25mm2，也可以是感应电极521的面积为9mm2～25mm2，还可以是驱动电极511和感应电极521的面积均为9mm2～25mm2。9mm2～25mm2具体可以是10mm2、12mm2、14mm2、16mm2、20mm2或23mm2。在驱动电极511的形状为菱形时，驱动电极511的两条边长可以为3mm～5mm，例如3.2mm、3.8mm、4mm、4.3mm或4.7mm。示例性地，菱形驱动电极的一条边长为3.8mm，菱形驱动电极的另一条边长为4.7mm；或者，菱形驱动电极的一条边长为4mm，菱形驱动电极的另一条边长为4.5mm。
在像素密度>500PPI(Pixels Per Inch)的显示装置中，可通过金属网格的开口设计形成人眼不可识别的边长<0.3mm的阵列排布的触控电极，消除人眼对3～5mm边长组成的驱动电极的反射差异程度显示缺陷。对于中大尺寸像素密度<400PPI的显示装置，由于子像素的发光区面积较大，金属网格100开口受限于阻容负载，通过开口100A设计形成的最小触控电极的边长一般都大于0.3mm，容易被人眼识别到反射差异程度显示缺陷。在本公开的示例性实施例中，触控结构1000采用多金属边围成不对称形状的开口设计，在强光照射时，金属网格形成多方向反射，达到类似散射的效果，从而消除金属网格100的反射差异程度。
在一些实施例中，金属导线110的线宽可以为1μm～20μm，例如为2μm、3.5μm、4.7μm、8μm、15μm或18μm。金属导线110的线宽是指垂直金属导线110延伸方向的宽度，例如：金属导线110为直线金属导线110L时，金属导线110的宽度为其横截面的宽度；金属导线110为弧线金属导线110H时，金属导线110的宽度为截面宽度，该截面与所截位置的切线方向相垂直。
基于同一发明构思，参见图10和图11所示，本公开实施例还提供一种显示面板，其中，包括：衬底210，位于衬底一侧的显示功能层220，以及位于显示功能层200背离衬底一侧的如本公开实施例提供的触控结构1000；其中，结合图1E-图1H、图2E-图2K、图3E-图3H所示，显示功能层200包括多个子像素221，至少一个开口100A在衬底210的正投影至少包围一个子像素221在衬底220的正投影。
触控结构1000可以设置于显示功能层220的出光侧。
如图10所示，显示功能层220包括发光器件240。封装层250覆盖发光器件240，触控结构1000形成于封装层250上。在一些实施例中，在显示功能层220的出光侧还可以包括抗反射结构(例如圆偏光片)的情况下，触控结构1000形成于封装层250和抗反射结构之间，金属网格100可以直接形成于封装层250的表面，即金属网格100与封装层250的表面之间没有其他膜层。
上述衬底210可以为有机衬底，也可以为无机衬底。衬底210的材料可以是聚对苯二甲酸乙二酯(Polyethylene terephthalate，简称PET)、聚酰亚胺(Polyimide，简称PI)、环烯烃聚合物(Cyclo Olefin Polymer，简称COP)等。
显示功能层220可以包括形成子像素221的多个功能膜层，例如：形成薄膜晶体管270的各膜层、阳极222、发光层223、阴极224等。子像素221的发光区221A可以理解为子像素221的有效发光面，每个子像素221的发光区221A的轮廓具有至少三个不同的延伸方向。
在一些实施例中，如图10和图11所示，所述显示功能层200包括：像素界定层225，开设有多个出光口225A，每个出光口225A确定一个子像素的发光区221A；所述出光口225A的形状与所述子像素221的发光区221A的形状大致相同。
像素界定层225的结构类似网格状，由挡墙围成多个出光口225A，一个子像素区域内设有一个出光口225A，出光口225A被配置为确定子像素221的发光区221A，发光层223所发出的光线穿过出光口225A，得到发光区221A。因此，出光口225A的形状与所述子像素221的发光区221A的形状大致相同。
像素界定层225中被配置为同一颜色的子像素221的发光区221A的多个出光口225A可以是同一形状，被配置为不同颜色的子像素221的发光区221A的出光口225A可以是不同形状。
在一种可能的实施方式中，结合图1E-图1H、图2E-图2K、图3E-图3H所示，子像素221与开口100A一一对应，至少部分子像素221在衬底210的正投影与开口100A在衬底210的正投影形状相似。
在一种可能的实施方式中，结合图1E-图1H、图2E-图2K、图3E-图3H所示，部分子像素221在衬底210的正投影超出开口100A在衬底210的正投影以外。具体的，例如，绿色子像素G在衬底210的正投影超出开口100A在衬底210的正投影以外。
在一种可能的实施方式中，结合图1E-图1H、图2E-图2K所示，子像素221包括红色子像素R，绿色子像素G以及蓝色子像素B；重叠单元Z内，两个第一子开口单元1201通过复用一绿色子像素G所在的开口连接；两个第二子开口单元1202通过复用一绿色子像素所在的开口连接。

在一种可能的实施方式中，图2F-图2I所示，第一蓝色子像素B1在衬底210的正投影、第二蓝色子像素B2在衬底210的正投影，分别位于相邻的第 一外凸部b1在衬底210的正投影内与第二外凸部b2在衬底210的正投影内。
在一种可能的实施方式中，图1F、图1G、图2F所示，第一蓝色子像素B1与第二蓝色子像素B2为一体连接结构。
在一种可能的实施方式中，图1I、图2H-图2K所示，第一蓝色子像素B1与第二蓝色子像素B2为分离的结构。
在一种可能的实施方式中，图2J-图2K所示，第一蓝色子像素B1在衬底210的正投影、第二蓝色子像素B2在衬底210的正投影，分别位于两个第一外凸部b1在衬底210的正投影内。
基于同一发明构思，本公开实施例还提供一种触控显示装置，其中，包括如本公开实施例提供的显示面板。触控显示装置所能实现的有益效果与上述实施例中的显示面板900所能达到的有益效果相同，触控显示装置的结构上文已说明各结构，此处不再赘述。
尽管已描述了本发明的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。
显然，本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发明实施例的精神和范围。这样，倘若本发明实施例的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
