具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开的保护范围。
需要说明的是，在附图中，为了清楚和/或描述的目的，可以放大元件的尺寸和相对尺寸。如此，各个元件的尺寸和相对尺寸不必限于图中所示的尺寸和相对尺寸。在说明书和附图中，相同或相似的附图标号指示相同或相似的部件。
当元件被描述为“在”另一元件“上”、“连接到”另一元件或“结合到”另一元件时，所述元件可以直接在所述另一元件上、直接连接到所述另一元件或直接结合到所述另一元件，或者可以存在中间元件。然而，当元件被描述为“直接在”另一元件 “上”、“直接连接到”另一元件或“直接结合到”另一元件时，不存在中间元件。用于描述元件之间的关系的其他术语和/或表述应当以类似的方式解释，例如，“在……之间”对“直接在……之间”、“相邻”对“直接相邻”或“在……上”对“直接在……上”等。此外，术语“连接”可指的是物理连接、电连接、通信连接和/或流体连接。此外，X轴、Y轴和Z轴不限于直角坐标系的三个轴，并且可以以更广泛的含义解释。例如，X轴、Y轴和Z轴可彼此垂直，或者可代表彼此不垂直的不同方向。出于本公开的目的，“X、Y和Z中的至少一个”和“从由X、Y和Z构成的组中选择的至少一个”可以被解释为仅X、仅Y、仅Z、或者诸如XYZ、XY、YZ和XZ的X、Y和Z中的两个或更多个的任何组合。如文中所使用的，术语“和/或”包括所列相关项中的一个或多个的任何组合和所有组合。
需要说明的是，虽然术语“第一”、“第二”等可以在此用于描述各种部件、构件、元件、区域、层和/或部分，但是这些部件、构件、元件、区域、层和/或部分不应受到这些术语限制。而是，这些术语用于将一个部件、构件、元件、区域、层和/或部分与另一个相区分。因而，例如，下面讨论的第一部件、第一构件、第一元件、第一区域、第一层和/或第一部分可以被称为第二部件、第二构件、第二元件、第二区域、第二层和/或第二部分，而不背离本公开的教导。
为了便于描述，空间关系术语，例如，“上”、“下”、“左”、“右”等可以在此被使用，来描述一个元件或特征与另一元件或特征如图中所示的关系。应理解，空间关系术语意在涵盖除了图中描述的取向外，装置在使用或操作中的其它不同取向。例如，如果图中的装置被颠倒，则被描述为“在”其它元件或特征“之下”或“下面”的元件将取向为“在”其它元件或特征“之上”或“上面”。
在本文中，表述“重复单元”可以表示显示基板中设置有至少两个或两个以上单元并且这些单元紧邻重复。所述重复单元可以表示多个子像素的组合，例如，用来显示一个像素点的多个子像素的组合，多个“重复单元”在衬底基板上成阵列地重复排列。例如，一个重复单元可以包括至少一个像素，例如可以包括2个、3个、4个、或更多个子像素。此外，在本文中，为了描述方便，将位于第一显示区域中的重复单元称为第一重复单元，将位于第二显示区域中的重复单元称为第二重复单元。在本文中，表述“重复单元”也可以称为“像素结构”。
在本文中，表述“像素密度”表示单位面积内的重复单元或子像素的个数。类似地，表述“分布密度”表示单位面积内的部件(例如重复单元、子像素、隔垫物等) 的个数。
在本文中，除非另有特别说明，表述“开口”表示像素界定层在每一个子像素中的开口，该开口暴露子像素的发光器件的阳极结构的至少一部分，发光器件的发光层的至少一部分也位于该开口中，即，该开口对应子像素的发光区域。
在本文中，除非另有特别说明，表述“开口的中心”表示该开口在衬底基板上的正投影的几何中心或形心。例如，在开口为圆形的情况下，开口的中心为该圆形的圆心；在开口为椭圆的情况下，开口的中心为该椭圆的中心，即椭圆的长轴和短轴的交点；在开口为矩形的情况下，开口的中心为该矩形的中心，即矩形的两条对角线的交点。
在本文中，除非另有特别说明，表述“A和B基本位于平行于第一排列方向延伸的同一直线上”包括以下情况：A和B位于平行于第一排列方向延伸的同一直线上；A和B的位置在垂直于第一排列方向的方向上存在一定的误差，该误差小于等于±5微米。
在本文中，除非另有特别说明，“第一开口与第二开口之间的距离”等类似表述表示的是第一开口的中心与第二开口的中心之间的距离，“第一开口与第二开口之间的间隔距离”等类似表述表示的是第一开口最靠近第二开口的边缘与第二开口最靠近第一开口的边缘之间的距离。
应该理解，“图形的平移”表示：在平面内，将一个图形沿某个方向移动一定的距离，这样的图形运动叫做平移。一个图形经过平移后得到一个新的图形，这个图形能与原图形相互重合，只是位置发生了变化。换句话说，在平面内，一个图形和另一个图形仅通过平移运动能相互重合，可以认为这两个图形是平移重合的。相应地，在平面内，一个图形和另一个图形仅通过平移运动不能相互重合，可以认为这两个图形是非平移重合的。
“图形的旋转”表示：在平面内，将一个图形绕一个定点按某个方向转动一个角度，这样的图形运动称为图形的旋转。这个定点被称为旋转中心，转动的角称为旋转角。旋转不改变图形的形状和大小。在平面内，一个图形和另一个图形通过平移和旋转运动能相互重合，可以认为这两个图形是非平移重合的，而是旋转重合的。
在本文中，除非另有特别说明，“图形形状不同”表示：两个图形的形状是不同的；如果两个图形的形状相同、但面积不同，不属于“图形形状不同”的情形。例如，两个图形既不是平移重合的，又不是旋转重合的。
在本文中，为了方便描述，使用方向性表述“第一排列方向”、“第二排列方向”、“第一方向”、“第二方向”，例如，“第一排列方向X”、“第二排列方向Y”、“第一方向M1”、“第二方向M2”，示例性地，第一排列方向X和第二排列方向Y可以用于表示各个子像素的排列方向，该排列方向可能与相邻两个子像素的发光区的几何中心连线方向平行，也可能不平行。例如，第一排列方向与第二排列方向相交。例如，第一排列方向与第二排列方向之间的夹角可以为80-100度。例如，第一排列方向与第二排列方向之间的夹角可以为85-95度。例如，第一排列方向和第二排列方向可以垂直，但不限于此，也可以不垂直。在本公开的实施例中，第一排列方向和第二排列方向可以互换。第一方向M1和第二方向M2可以用于表示与第一排列方向X和第二排列方向Y相交的方向，应该理解，第一方向M1和第二方向M2也可以用于表示各个子像素的排列方向，该排列方向可能与相邻两个子像素的发光区的几何中心连线方向平行，也可能不平行。例如，第一方向与第二方向相交。例如，第一方向与第二方向之间的夹角可以为80-100度。例如，第一方向与第二方向之间的夹角可以为85-95度。例如，第一方向和第二方向可以垂直，但不限于此，也可以不垂直。在本公开的实施例中，第一方向和第二方向可以互换。例如，在本公开的实施例中，示例性的，第一排列方向X和第二排列方向Y可以分别表示行方向和列方向，二者彼此垂直；第一方向M1和第二方向M2彼此垂直，且它们分别与第一排列方向X和第二排列方向Y成约45°的夹角。
本公开的实施例提供一种显示基板，所述显示基板包括：衬底基板；多个子像素，所述多个子像素沿第一排列方向和第二排列方向成阵列地设置于所述衬底基板上，所述多个子像素包括多个发光区；第一电极层，所述第一电极层位于所述衬底基板上，所述第一电极层包括多个阳极结构；以及像素界定层，位于所述第一电极层远离所述衬底基板的一侧，所述像素界定层包括多个开口以限定所述多个发光区，其中，对于所述多个子像素中的至少一些子像素而言，每一个子像素的开口在所述衬底基板上的正投影落入该子像素的阳极结构在所述衬底基板上的正投影内，每一个子像素的开口在所述衬底基板上的正投影的图形与所述子像素的阳极结构在所述衬底基板上的正投影的图形形状不同；以及每一个子像素的阳极结构在所述衬底基板上的正投影的图形的对称轴线的数量大于该子像素的开口在所述衬底基板上的正投影的图形的对称轴线的数量。在本公开的实施例中，对于具有异形形状的开口或发光区，将其对应的阳极结构设计为同一形状，能够缩小阳极结构的排列周期(即排列节距)，使得干涉条纹人 眼不可见，从而能够显著改善显示基板的使用体验。
图1A是根据本公开的一些示例性实施例的显示装置的平面示意图，其中示意性示出了显示装置包括的显示基板的平面结构。图1B是根据本公开的一些示例性实施例的显示装置沿图1A中的线AA’截取的截面示意图。
如图1A所示，根据本公开实施例的显示装置包括显示基板10。该显示基板10包括显示区域，所述显示区域可以包括显示区域AA。例如，显示区域AA的形状可以为圆形、椭圆形或矩形，但本公开的实施例不限于此。又例如，显示区域AA的形状可以为矩形、圆角矩形或者其它合适的形状。
如图1B所示，所述显示基板10可以包括衬底基板1和设置在衬底基板1上的多个像素单元，每个像素单元可以包括多个子像素。
在图1A至图1B所示的显示基板中，可以采用OLED显示技术。由于OLED显示基板具有广视角、高对比度、快响应、低功耗、可折叠、柔性等优势，在显示产品中得到越来越广泛地应用。
例如，所述显示基板10还可以包括设置在衬底基板1上的驱动电路层、发光器件层和封装层。例如，图1B中示意性地示出了像素驱动电路层3、发光器件层4和封装层5。像素驱动电路层3包括像素驱动电路结构，发光器件层4包括例如OLED的发光器件。所述像素驱动电路结构控制各个子像素的发光器件发光，以实现显示功能。该像素驱动电路结构包括薄膜晶体管、存储电容器以及各种信号线。所述各种信号线包括栅线、数据线、ELVDD电源线和ELVSS电源线等，以便为每个子像素中的像素驱动电路提供控制信号、数据信号、电源电压等各种信号。
图2A为示意性示出根据本公开的一些示例性实施例的显示基板在显示区域中的子像素排布方式的局部示意图。图2B为图2A中的单个子像素的放大图。图2C为沿图2B中的线BB’截取的示意截面图。图3示意性示出了图2A所示的实施例下的干涉条纹的仿真结果。
如图2A所示，显示基板10包括多个子像素。例如，多个子像素包括多个第一颜色子像素SP1、多个第二颜色子像素SP2以及多个第三颜色子像素SP3。多个第一颜色子像素SP1和多个第三颜色子像素SP3沿第一排列方向(如图2A所示的X方向，又称为行方向)交替设置以形成第一像素行01，多个第二颜色子像素SP2沿第一排列方向X排列以形成第二像素行02，第一像素行01和第二像素行02沿与第一排列方向X交叉的第二排列方向(如图2A所示的Y方向，又称为列方向)交替设置且在第一 排列方向X上彼此错开。例如，相邻的第一颜色子像素SP1和第二颜色子像素SP2沿第一方向M1排列，第一方向M1与第一排列方向X和第二排列方向Y均相交。如图2A所示，多个第一颜色子像素SP1和多个第三颜色子像素SP3沿第二排列方向Y交替设置以形成多个第一像素列03，多个第二颜色子像素SP2沿第一排列方向X和第二排列方向Y均阵列排布以形成多个第二像素行02和多个第二像素列04，多个第一像素列03和多个第二像素列04沿第一排列方向X交替设置且在第二排列方向Y上彼此错开，即一个第二颜色子像素SP2所在第二像素行02位于相邻两个第一像素行01之间，且该第二颜色子像素SP2所在第二像素列04位于相邻两个第一像素列03之间。
如图2A所示，显示基板包括呈阵列排布的多个重复单元A，每个重复单元A包括两行四列子像素，也即每个重复单元A中包括一个第一颜色子像素SP1、一个第三颜色子像素SP3和两个第二颜色子像素SP2，第一颜色子像素SP1和第三颜色子像素SP3为共用子像素，通过虚拟算法，可以使得四个子像素实现两个虚拟像素单元的显示。例如，同一行重复单元中，第二个重复单元中的第一颜色子像素SP1、第一个重复单元中的第三颜色子像素SP3以及第一个重复单元中靠近第二个重复单元的第二颜色子像素SP2形成一个虚拟像素单元，同时第二个重复单元中的第一颜色子像素SP1还与该重复单元中的第三颜色子像素SP3以及与该重复单元中的靠近第一个重复单元的第二颜色子像素SP2形成一个虚拟像素单元；另外，第二个重复单元中的第三颜色子像素SP3还与该重复单元中的另一个第二颜色子像素SP2以及第三个重复单元中的第一颜色子像素SP1形成一个虚拟像素单元，从而可以有效的提高该显示基板的分辨率。
本公开实施例中的子像素指发光器件结构，第一颜色子像素、第二颜色子像素和第三颜色子像素为发出不同颜色光的子像素。本公开实施例以第一颜色子像素为红色子像素，第二颜色子像素为绿色子像素，第三颜色子像素为蓝色子像素为例进行说明。但第一颜色子像素为红色子像素，第二颜色子像素为绿色子像素以及第三颜色子像素为蓝色子像素并不构成对本公开实施例保护范围的限制。
例如，第一颜色子像素SP1和第三颜色子像素SP3为共用子像素，根据二者发光光谱，这两者的发光区的面积均大于第二颜色子像素SP2的面积。
例如，至少一个蓝色子像素的发光区的面积大于至少一个红色子像素的发光区的面积，至少一个红色子像素的发光区的面积大于至少一个绿色子像素的发光区的面积，以延长显示基板的使用寿命。例如，相同颜色子像素的发光区的面积基本相等。
需要说明的是，在图2A以及下文类似的图中，位于最里面的图形表示子像素的开口或发光区，比所述子像素的开口或发光区的图形的面积大且基本包围所述开口的轮廓为子像素的阳极结构的轮廓线。
如图2A所示，每个子像素包括发光区200。例如，显示基板10包括设置在衬底基板1上的像素界定层8(参照图12)，各子像素的发光区200的形状由像素界定层8中的开口限定，则各子像素的发光区200的形状与像素界定层8的开口的形状大致相同。
例如，结合参照图2A和图12，像素界定层8包括多个第一开口101、多个第二开口102以及多个第三开口103。第一开口101限定了第一颜色子像素SP1的第一发光区，第二开口102限定了第二颜色子像素SP2的第二发光区，第三开口103限定了第三颜色子像素SP3的第三发光区。
例如，显示基板包括衬底基板，各子像素以及像素界定层8设置在衬底基板上。各子像素包括有机发光元件，有机发光元件包括层叠设置的第一电极、发光层以及第二电极，第一电极位于发光层面向衬底基板的一侧。例如，第一电极的至少部分位于像素界定层面向衬底基板的一侧。当发光层形成在上述像素界定层8中的开口中时，位于发光层两侧的第一电极和第二电极能够驱动像素界定层8的开口中的发光层进行发光。例如，发光层与第一电极之间以及发光层与第二电极之间的至少之一中还设置有功能层。例如，功能层包括空穴注入层，空穴传输层，电子传输层，空穴阻挡层，电子阻挡层，电子注入层，辅助发光层，界面改善层，增透层等中的任意一层或多层。
例如，结合参照图2A和图12，所述显示基板10包括第一电极层41，所述第一电极层41位于所述衬底基板1上，所述第一电极层41包括多个阳极结构。该阳极结构构成所述有机发光元件的阳极的主体部分。为了描述方便，可以将第一颜色子像素SP1的有机发光元件包括的阳极结构称为第一阳极结构401，将第二颜色子像素SP2的有机发光元件包括的阳极结构称为第二阳极结构402，将第三颜色子像素SP3的有机发光元件包括的阳极结构称为第三阳极结构403。
例如，像素界定层的开口在衬底基板上的正投影位于相应的发光层在衬底基板上的正投影内，即发光层覆盖了像素界定层的开口。各子像素的开口在衬底基板上的正投影分别落入各自的阳极结构在衬底基板上的正投影内。例如，第一颜色子像素SP1的第一开口101在衬底基板1上的正投影落入第一颜色子像素SP1的第一阳极结构401在衬底基板1上的正投影内，第二颜色子像素SP2的第二开口102在衬底基板1上的 正投影落入第二颜色子像素SP2的第二阳极结构402在衬底基板1上的正投影内，第三颜色子像素SP3的第三开口103在衬底基板1上的正投影落入第三颜色子像素SP3的第三阳极结构403在衬底基板1上的正投影内。在本公开的实施例中，阳极结构的面积比开口的面积大，有利于保证子像素的开口中的有机发光材料均匀发光。
结合参照图2A至图2C，各子像素的阳极结构在衬底基板上的正投影和各自的开口在衬底基板上的正投影具有相同的形状，二者仅面积不同。
在图2A所示的实施例中，示意性示出各子像素的开口的形状为包括圆角的图形，则各子像素的发光区的形状也为包括圆角的图形，例如各子像素的阳极结构的形状也可以为包括圆角的图形。像素界定层的开口的图形可以包括四条直边，至少两条相邻直边通过曲线段连接，该曲线段形成了圆角。但本公开的实施例不限于此，各子像素的发光区的图形还可以包括三条直边、五条直边或者六条直边，则发光区包括的顶角的数量也随之变化。
例如，在图2A所示的实施例中，第一颜色子像素SP1的第一开口101在衬底基板1上的正投影具有圆角矩形的形状，相应地，第一颜色子像素SP1的第一阳极结构401在衬底基板1上的正投影也具有圆角矩形的形状。第二颜色子像素SP2的第二开口102在衬底基板1上的正投影具有圆角矩形的形状，相应地，第二颜色子像素SP2的第二阳极结构402在衬底基板1上的正投影也具有圆角矩形的形状。第三颜色子像素SP3的第三开口103在衬底基板1上的正投影具有不规则的形状(例如，矩形被截去一个顶角)，相应地，第三颜色子像素SP3的第三阳极结构403在衬底基板1上的正投影也具有该不规则的形状(例如，矩形被截去一个顶角)。
例如，各子像素的阳极结构相对于各自的开口为等比例放大的。参照图2C，在任一子像素的开口的相对侧，该子像素的阳极结构超出开口的轮廓边缘的宽度相等，例如，wd1＝wd2。
在本公开的实施例中，第三颜色子像素SP3的第三开口103在衬底基板1上的正投影和第三颜色子像素SP3的第三阳极结构403在衬底基板1上的正投影具有不规则多边形的形状，例如，参照图5，该不规则多边形可以被截去至少一个第一顶角301以形成至少一个第一角部1011，该不规则多边形还可以包括第二角部1012，该第二角部1012与第一角部1011相对。
参照图2A，第三颜色子像素SP3可以包括至少两种类型子像素，一种类型子像素中，第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向为D1；另一种 类型子像素中，第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向为D4，两个方向不同。
例如，如图2A所示，方向D1与方向D4可以平行且相反，但不限于此，两个方向也可以相交。
例如，如图2A所示，第三颜色子像素SP3包括两种不同类型子像素，一种类型子像素的第一角部1011的朝向向右，另一种类型子像素的第一角部1011的朝向向左。
本公开实施例不限于此，例如，第三颜色子像素中的两种不同类型子像素中第一角部的朝向还可以分别向上和向下，或者向上和向左，或者向上和向右，或者向下和向右，或者向下和向左。
当然，本公开实施例不限于第三颜色子像素包括两种不同类型，还可以第一颜色子像素和第二颜色子像素的至少之一包括两种不同类型子像素，且同种颜色子像素中不同类型子像素的判断标准可参考上述第三颜色子像素中不同类型子像素的判断标准。
例如，具有不同类型子像素的同一种颜色子像素中，沿第一排列方向和第二排列方向的至少之一的方向相邻的两个子像素为不同类型子像素。
例如，如图2A所示，沿第一排列方向排列的相邻两个第三颜色子像素SP3中的第一角部1011的朝向不同，例如分别向左和向右，但不限于此，还可以分别向上和向下，或者向上和向左，或者向上和向右，或者向下和向右，或者向下和向左。
例如，如图2A所示，沿第二排列方向排列的相邻两个第三颜色子像素SP3中的第一角部1011的朝向不同，例如分别向上和向下，但不限于此，还可以分别向左和向右，或者向上和向左，或者向上和向右，或者向下和向右，或者向下和向左。
本公开实施例不限于此，上述至少一种颜色子像素还可以包括三种类型子像素，三种不同类型子像素的第一角部的朝向可以包括向上、向下、向左和向右之中的任意三者，且位于同一行(或同一列)的子像素可以包括同种类型子像素，也可以包括至少两种类型子像素，在第一排列方向和第二排列方向至少之一的方向相邻的两个子像素可以为同种类型子像素，也可以为不同类型子像素，可以根据实际产品需求进行设置。例如，还可以一种颜色子像素包括上述三种类型子像素、两种颜色子像素中的每种颜色子像素均包括上述三种类型子像素，或者三种颜色子像素中的每种颜色子像素均包括上述三种类型子像素，本公开实施例对此不作限制。
例如，如图2A所示，上述至少一种颜色子像素包括四种不同类型子像素，如第 一类型子像素1001、第二类型子像素1002、第三类型子像素1003和第四类型子像素1004，不同类型子像素中，第一角部1011的顶点指向第二角部1012的顶点的方向不同。例如，不同类型子像素中第一角部1011的位置不同。例如，不同类型子像素中第一角部1011的朝向不同。
例如，各类型子像素的形状相同，或面积相同。例如，各类型子像素的形状和面积均相同。例如，不同类型子像素的数量大致相同。例如，第一类型子像素1001、第二类型子像素1002、第三类型子像素1003以及第四类型子像素1004中，任意两种类型子像素的数量比为0.8～1.2。例如，所述第一类型子像素1001和所述第二类型子像素1002的数量比为0.8～1.2，所述第三类型子像素1003和所述第四类型子像素1004的数量比为0.8～1.2。例如，第一类型子像素1001、第二类型子像素1002、第三类型子像素1003以及第四类型子像素1004中，任意两种类型子像素的数量比为0.9～1.1。
例如，如图2A所示，第一类型子像素1001、第二类型子像素1002、第三类型子像素1003和第四类型子像素1004中，第一角部1011的顶点指向第二角部1012的顶点的方向分别为方向D2、方向D3、方向D4和方向D1。例如，第一类型子像素1001的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D2；第二类型子像素1002的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D3；第三类型子像素1003的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D4；第四类型子像素1004的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D1。
例如，如图2A所示，第一类型子像素1001和第二类型子像素1002中，第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向相反，例如平行于第二排列方向Y；第三类型子像素1003和第四类型子像素1004中，第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向相反，例如平行于第一排列方向X。由此，方向D2和方向D3相反，且方向D4和方向D1相反。
本公开实施例示意性的示出第三颜色子像素包括四种不同类型子像素，但不限于此，还可以第一颜色子像素和第二颜色子像素的至少一种颜色子像素包括上述四种不同类型子像素，其他颜色子像素中不同类型子像素的第一角部的顶点指向第二角部的顶点的方向可以平行于第一排列方向或者第二排列方向，也可以与第一排列方向或第二排列方向相交。
本公开实施例提供的显示基板中，通过设置四种不同类型子像素，有利于改善该 显示基板显示时的色偏问题。此外，一般显示基板中，各不同颜色子像素的开口区包括的四个角部的形状均相同，相对于这种显示基板，本公开实施例提供的显示基板通过设置上述四种不同类型子像素，有利于减少显示基板显示时出现的颗粒感。
在图2A所示的实施例中，各个子像素的阳极结构相对于各自的开口是等比例放大的。也就是说，在第一类型子像素1001、第二类型子像素1002、第三类型子像素1003和第四类型子像素1004中，就子像素的阳极结构而言，第一角部1011的顶点指向第二角部1012的顶点的方向分别为方向D2、方向D3、方向D4和方向D1。例如，第一类型子像素1001的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D2；第二类型子像素1002的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D3；第三类型子像素1003的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D4；第四类型子像素1004的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D1。这样，各子像素的阳极结构形成了周期性的不规则图形排布。发明人经研究发现，当各子像素的阳极结构形成周期性的不规则图形排布时，不同行和/或列的光衍射和反射的路径不同，会出现周期性的条纹(参照图3，示意性示出了图2A所示的实施例下的干涉条纹)，极大影响用户的使用体验。
图4A为示意性示出根据本公开的一些示例性实施例的显示基板在显示区域中的子像素排布方式的局部示意图。图4B为图4A中的单个子像素的放大图。图4C为沿图4B中的线CC’截取的示意截面图。图5为图4A中所示的单个子像素的开口的放大图。图6示意性示出了图4A所示的实施例下的干涉条纹的仿真结果。图7为示意性示出根据本公开的一些示例性实施例的显示基板阳极的具体结构的局部示意图。图8A为示意性示出根据本公开的另一些示例性实施例的显示基板在显示区域中的子像素排布方式的局部示意图。图8B至图8D分别为根据本公开的另一些示例性实施例的显示基板在显示区域中的单个子像素的放大图。图9A为示意性示出根据本公开的又一些示例性实施例的显示基板在显示区域中的子像素排布方式的局部示意图。图9B为图9A中的单个子像素的放大图。图10A为示意性示出根据本公开的又一些示例性实施例的显示基板在显示区域中的子像素排布方式的局部示意图。图10B为图10A中的单个子像素的放大图。图11A为示意性示出根据本公开的又一些示例性实施例的显示基板在显示区域中的子像素排布方式的局部示意图。图11B为图11A中的单个子像素的放大图。
需要说明的是，在下面的描述中，部分内容可以参考上文针对图2A至图2C的描述，下面主要描述区别于图2A至图2C的内容。相应地，为了避免混淆，具有相同或相似结构的部件、元件或部分采用相同的附图标记表示，具有不同结构或形状的部件、元件或部分采用不同的附图标记表示。
如图4A所示，显示基板10包括多个子像素。例如，多个子像素包括多个第一颜色子像素SP1、多个第二颜色子像素SP2以及多个第三颜色子像素SP3。多个第一颜色子像素SP1和多个第三颜色子像素SP3沿第一排列方向(如图4A所示的X方向，又称为行方向)交替设置以形成第一像素行01，多个第二颜色子像素SP2沿第一排列方向X排列以形成第二像素行02，第一像素行01和第二像素行02沿与第一排列方向X交叉的第二排列方向(如图4A所示的Y方向，又称为列方向)交替设置且在第一排列方向X上彼此错开。例如，相邻的第一颜色子像素SP1和第二颜色子像素SP2沿第一方向M1排列，第一方向M1与第一排列方向X和第二排列方向Y均相交。如图4A所示，多个第一颜色子像素SP1和多个第三颜色子像素SP3沿第二排列方向Y交替设置以形成多个第一像素列03，多个第二颜色子像素SP2沿第一排列方向X和第二排列方向Y均阵列排布以形成多个第一像素列03和多个第二像素列04，多个第一像素列03和多个第二像素列04沿第一排列方向X交替设置且在第二排列方向Y上彼此错开，即一个第二颜色子像素SP2所在第二像素行02位于相邻两个第一像素行01之间，且该第二颜色子像素SP2所在第二像素列04位于相邻两个第一像素列03之间。
如图4A所示，显示基板包括呈阵列排布的多个重复单元A，每个重复单元A包括两行四列子像素，也即每个重复单元A中包括一个第一颜色子像素SP1、一个第三颜色子像素SP3和两个第二颜色子像素SP2，第一颜色子像素SP1和第三颜色子像素SP3为共用子像素，通过虚拟算法，可以使得四个子像素实现两个虚拟像素单元的显示。例如，同一行重复单元中，第二个重复单元中的第一颜色子像素SP1、第一个重复单元中的第三颜色子像素SP3以及第一个重复单元中靠近第二个重复单元的第二颜色子像素SP2形成一个虚拟像素单元，同时第二个重复单元中的第一颜色子像素SP1还与该重复单元中的第三颜色子像素SP3以及与该重复单元中的靠近第一个重复单元的第二颜色子像素SP2形成一个虚拟像素单元；另外，第二个重复单元中的第三颜色子像素SP3还与该重复单元中的另一个第二颜色子像素SP2以及第三个重复单元中的第一颜色子像素SP1形成一个虚拟像素单元，从而可以有效的提高该显示基板的分辨率。
如图4A所示，每个子像素包括发光区200。例如，显示基板10包括设置在衬底基板1上的像素界定层8(参照图12)，各子像素的发光区200的形状由像素界定层8中的开口限定，则各子像素的发光区200的形状与像素界定层8的开口的形状大致相同。
例如，结合参照图4A和图12，像素界定层8包括多个第一开口101、多个第二开口102以及多个第三开口103。第一开口101限定了第一颜色子像素SP1的第一发光区，第二开口102限定了第二颜色子像素SP2的第二发光区，第三开口103限定了第三颜色子像素SP3的第三发光区。
图12为沿图1中的线AA’截取的剖面示意图，其示意性示出了根据本公开的一些示例性实施例的显示基板的具体结构。结合参照图1、图2、图4A和图12，显示基板10包括依次叠置在衬底基板1上的像素驱动电路层，其中，像素驱动电路层可以包括薄膜晶体管T、绝缘层31、平坦化层32和有机发光元件41。有机发光元件41包括位于第一电极层中的第一电极(例如阳极)41A、位于第二电极层中的第二电极(例如阴极)41C以及位于第一电极41A与第二电极41C之间的发光层41B。有机发光元件41的第一电极41A通过贯穿平坦化层32的阳极连接孔VH1与晶体管电连接。其中，像素驱动电路层可以包括半导体层，第一绝缘层，第一栅极层，第二绝缘层，第二栅极层，层间绝缘层，源漏金属层等。在一些实施例中，像素驱动电路可以包括7个薄膜晶体管(例如驱动晶体管，数据写入晶体管，补偿晶体管，复位晶体管，发光控制晶体管等)，和一个存储电容，其中至少一个薄膜晶体管和发光器件直接连接，例如发光控制晶体管。图12只是示意性示出一个薄膜晶体管T，薄膜晶体管T至少包括位于半导体层中的有源层，以及源极接触部分，漏极接触部分，位于第一栅极层中的栅极，位于源漏金属层中的源极和漏极。
需要说明的是，在本文中，除非另有说明，“过孔”或“连接孔”用于电连接位于不同的导电层中的部件，在本公开的实施例中，“过孔”或“连接孔”还可以采用其他替代形式，例如，可以用于电连接位于不同的导电层中的部件的“凹槽”来替代所述过孔或连接孔。
例如，第一电极41A可以包括ITO等透明导电材料，本公开的实施例对第一电极41A的具体材料不做限定。例如，第二电极41C可以为显示基板10上整个表面上形成的结构(例如至少全部覆盖整个显示区)，第二电极41C例如可以包括锂(Li)、铝(Al)、镁(Mg)、银(Ag)等金属材料。例如，由于第二电极41C可以形成为很薄的一层， 因此第二电极41C具有良好的透光性。
所述显示基板10还可以包括像素界定层8。例如，所述像素界定层8可以具有多个开口。例如，一些开口位于显示区域AA中，每一个开口暴露有机发光元件41的第一电极的一部分。
结合参照图7和图12，第一电极41A包括阳极结构413和阳极连接部422，所述阳极连接部422的至少一部分的厚度与所述阳极结构413的厚度不同。具体地，在所述过孔VH1处，第一电极的阳极连接部422连接至下方的薄膜晶体管的源极或漏极，所以，所述阳极连接部422的至少一部分的厚度大于所述阳极结构413的厚度。
应该理解，阳极结构413为阳极(即第一电极)的主体部分，阳极连接部422为阳极(即第一电极)的辅助部分，它是为了方便设置过孔VH1而设计的。在本公开的实施例中，仅图7示意性示出了阳极的整体结构，在其他附图中，使用阳极的主体部分(即阳极结构)表示阳极的主体轮廓。也就是说，在本文中，除非另有说明，使用阳极结构在衬底基板上的正投影表示各个子像素的阳极的图案。
图13是根据本公开的一些示例性实施例的显示基板的一个像素驱动电路的等效电路图。
下面，以7T1C像素驱动电路为例，对所述像素驱动电路的结构进行详细描述，但是，本公开的实施例并不局限于7T1C像素驱动电路，在不冲突的情况下，其它已知的像素驱动电路结构都可以应用于本公开的实施例中。
如图13所示，所述像素驱动电路可以包括：多个薄膜晶体管以及一个存储电容器Cst。所述像素驱动电路用于驱动有机发光二极管(即OLED)。多个薄膜晶体管包括第一晶体管T1、第二晶体管T2、第三晶体管T3、第四晶体管T4、第五晶体管T5、第六晶体管T6和第七晶体管T7。每一个晶体管均包括栅极、源极和漏极。
所述显示基板还可以包括多根信号线，例如，所述多根信号线包括：用于传输扫描信号Sn的扫描信号线61，用于传输复位控制信号RESET(即前一行的扫描信号)的复位信号线62，用于传输发光控制信号En的发光控制线63，用于传输数据信号Dm的数据线64，用于传输驱动电压VDD的驱动电压线65，用于传输初始化电压Vint的初始化电压线66，以及用于传输VSS电压的电源线67。
第一晶体管T1的栅极G1电连接至存储电容器Cst的一端Cst1，第一晶体管T1的源极S1经由第五晶体管T5电连接至驱动电压线65，第一晶体管T1的漏极D1经由第六晶体管T6电连接至OLED的阳极。第一晶体管T1根据第二晶体管T2的开关 操作接收数据信号Dm，以向OLED供应驱动电流Id。
第二晶体管T2的栅极G2电连接至扫描信号线61，第二晶体管T2的源极S2电连接至数据线64，第二晶体管T2的漏极D2经由第五晶体管T5电连接至驱动电压线65，同时电连接至第一晶体管T1的源极S1。第二晶体管T2根据通过扫描信号线61传输的扫描信号Sn导通，以执行开关操作来将被传输至数据线64的数据信号Dm传输至第一晶体管T1的源极S1。
第三晶体管T3的栅极G3电连接至扫描信号线61，第三晶体管T3的源极S3经由第六晶体管T6电连接至OLED的阳极，同时电连接至第一晶体管T1的漏极D1。并且第三晶体管T3的漏极D3与存储电容器Cst的一端(即第一电容电极)Cst1、第四晶体管T4的漏极D4以及第一晶体管T1的栅极G1电连接在一起。第三晶体管T3根据通过扫描信号线61传输的扫描信号Sn导通，以将第一晶体管T1的栅极G1和漏极D1彼此连接，从而执行第一晶体管T1的二极管连接。
第四晶体管T4的栅极G4电连接至复位控制信号线62，第四晶体管T4的源极S4电连接至初始化电压线66。并且第四晶体管T4的漏极D4与存储电容器Cst的一端Cst1、第三晶体管T3的漏极D3以及第一晶体管T1的栅极G1电连接。第四晶体管T4根据通过复位控制信号线62传输的复位控制信号Sn-1导通，以将初始化电压Vint传输至第一晶体管T1的栅极G1，从而执行初始化操作来将第一晶体管T1的栅极G1的电压初始化。
第五晶体管T5的栅极G5电连接至发光控制线63，第五晶体管T5的源极S5电连接至驱动电压线65。并且第五晶体管T5的漏极D5与第一晶体管T1的源极S1和第二晶体管T2的漏极D2电连接。
第六晶体管T6的栅极G6电连接至发光控制线63，第六晶体管T6的源极S6电连接至第一晶体管T1的漏极D1且电连接至第三晶体管T3的源极S3。并且第六晶体管T6的漏极D6电连接至OLED的阳极。第五晶体管T5和第六晶体管T6根据通过发光控制线63传输的发光控制信号En并发(例如同时)导通，以将驱动电压ELVDD传输至OLED，从而允许驱动电流Id流进OLED中。
第七晶体管T7包括：栅极G7，连接至复位控制信号线62；源极S7，连接至第六晶体管T6的漏极D6和OLED的阳极；以及漏极D7，连接至初始化电压线66。第七晶体管T7将复位控制信号Sn-1从复位控制信号线62传送至栅极G7。
存储电容器Cst的另一端Cst2电连接至驱动电压线65，并且OLED的阴极电连接 至电源线67，以接收公共电压ELVSS。相应地，OLED从第一晶体管T1接收驱动电流Id来发光，从而显示图像。
需要说明的是，在图13中，各个薄膜晶体管T1、T2、T3、T4、T5、T6和T7是p沟道场效应晶体管，但是，本公开的实施例不局限于此，薄膜晶体管T1、T2、T3、T4、T5、T6和T7中的至少一些可以是n沟道场效应晶体管。
在操作中，在初始化阶段期间，具有低电平的复位控制信号Sn-1通过复位控制信号线62供应。随后，初始化薄膜晶体管T4基于复位控制信号Sn-1的低电平导通，并且来自初始化电压线66的初始化电压Vint通过初始化薄膜晶体管T4传送至驱动薄膜晶体管T1的栅极G1。因此，驱动薄膜晶体管T1由于初始化电压Vint而被初始化。
在数据编程阶段期间，具有低电平的扫描信号Sn通过扫描信号线61供应。随后，开关薄膜晶体管T2和补偿薄膜晶体管T3基于扫描信号Sn的低电平导通。因此，驱动薄膜晶体管T1通过导通的补偿薄膜晶体管T3被置于二极管连接状态并且在正方向上偏置。
随后，通过从经由数据线64供应的数据信号Dm中减去驱动薄膜晶体管T1的阈值电压Vth获得的补偿电压Dm+Vth(例如，Vth是负值)施加至驱动薄膜晶体管T1的栅极G1。随后，驱动电压ELVDD和补偿电压Dm+Vth施加至存储电容器Cst的两个端子，使得与相应端子之间的电压差对应的电荷存储在存储电容器Cst中。
在发光阶段期间，来自发光控制线63的发光控制信号En从高电平变为低电平。随后，在发光阶段期间，第一发光控制薄膜晶体管T5和第二发光控制薄膜晶体管T6基于发光控制信号En的低电平导通。
随后，基于驱动薄膜晶体管T1的栅极G1的电压与驱动电压ELVDD之间的差生成驱动电流。与驱动电流和旁路电流之间的差对应的驱动电流Id通过第二发光控制薄膜晶体管T6供应给OLED。
在发光阶段期间，基于驱动薄膜晶体管T1的电流-电压关系，驱动薄膜晶体管T1的栅源电压由于存储电容器Cst而保持在(Dm+Vth)-ELVDD处。驱动电流Id与(Dm-ELVDD)2成比例。因此，驱动电流Id可以不受驱动薄膜晶体管T1的阈值电压Vth变动的影响。
例如，在本公开的各个实施例中，衬底基板1可以为玻璃基板、石英基板、金属基板或树脂类基板等，可以是刚性基板或柔性基板，本公开的实施例对此不作限制。
例如，结合参照图4A和图12，所述显示基板10包括第一电极层，所述第一电极 层位于所述衬底基板1上，所述第一电极层包括多个阳极结构。该阳极结构构成所述有机发光元件的阳极的主体部分。为了描述方便，可以将第一颜色子像素SP1的有机发光元件包括的阳极结构称为第一阳极结构401，将第二颜色子像素SP2的有机发光元件包括的阳极结构称为第二阳极结构402，将第三颜色子像素SP3的有机发光元件包括的阳极结构称为第三阳极结构403。
结合参照图4A、图8A、图9A、图10A和图11A，像素界定层的开口在衬底基板上的正投影位于相应的发光层在衬底基板上的正投影内，即发光层覆盖了像素界定层的开口。各子像素的开口在衬底基板上的正投影分别落入各自的阳极结构在衬底基板上的正投影内。例如，第一颜色子像素SP1的第一开口101在衬底基板1上的正投影落入第一颜色子像素SP1的第一阳极结构401在衬底基板1上的正投影内，第二颜色子像素SP2的第二开口102在衬底基板1上的正投影落入第二颜色子像素SP2的第二阳极结构402在衬底基板1上的正投影内，第三颜色子像素SP3的第三开口103在衬底基板1上的正投影落入第三颜色子像素SP3的第三阳极结构403在衬底基板1上的正投影内。在本公开的实施例中，阳极结构的面积比开口的面积大，有利于保证子像素的开口中的有机发光材料均匀发光。
结合参照图4A至图4C、图8A至图8D、图9A至图9B、图10A至图10B和图11A至图11B，对于所述多个子像素中的至少一些子像素而言，每一个子像素的开口在所述衬底基板上的正投影的图形与所述子像素的阳极结构在所述衬底基板上的正投影的图形形状不同；以及每一个子像素的阳极结构在所述衬底基板上的正投影的图形的对称轴线的数量大于该子像素的开口在所述衬底基板上的正投影的图形的对称轴线的数量。
例如，在图4A和图8A所示的实施例中，第一颜色子像素SP1的第一开口101在衬底基板1上的正投影具有圆角矩形的形状，相应地，第一颜色子像素SP1的第一阳极结构401在衬底基板1上的正投影也具有圆角矩形的形状。第二颜色子像素SP2的第二开口102在衬底基板1上的正投影具有圆角矩形的形状，相应地，第二颜色子像素SP2的第二阳极结构402在衬底基板1上的正投影也具有圆角矩形的形状。
参照图4A，第三颜色子像素SP3的第三开口103在衬底基板1上的正投影具有不规则的形状，例如，矩形被截去一个顶角，可以参照图5。不同地，第三颜色子像素SP3的第三阳极结构403在衬底基板1上的正投影具有规则的形状，例如，矩形或圆角矩形。
参照图8A，第三颜色子像素SP3的第三开口103在衬底基板1上的正投影具有不规则的形状，例如，矩形被截去一个顶角，可以参照图5。不同地，第三颜色子像素SP3的第三阳极结构403在衬底基板1上的正投影具有规则的形状，例如，圆形。
在图4A和图8A所示的实施例中，示意性示出各子像素的开口的形状为包括圆角的图形，则各子像素的发光区的形状也为包括圆角的图形，例如各子像素的阳极结构的形状也可以为包括圆角的图形。像素界定层的开口的图形可以包括四条直边，至少两条相邻直边通过曲线段连接，该曲线段形成了圆角。但本公开的实施例不限于此，各子像素的发光区的图形还可以包括三条直边、五条直边或者六条直边，则发光区包括的顶角的数量也随之变化。
结合参照图4A和图4B以及图8A和图8B，对于所述多个子像素中的至少一些子像素而言，每一个子像素的阳极结构在所述衬底基板上的正投影的图形相对于该子像素的开口在所述衬底基板上的正投影的图形是非等比例放大的。
图5为图4A或图8A所示的一个发光区的形状示意图。如图4A、图8A和图5所示，各个发光区200的每条边或其延长线依次连接形成多边形300，且至少部分子像素的所述多边形300的多个顶角301存在与对应的发光区200的多个角部001不交叠的区域N0；至少一个子像素的所述发光区200的多个角部001中，至少包括第一角部1011，所述第一角部1011和与其对应的所述多边形300的顶角301不交叠的区域N0的面积大于其他角部001的至少部分角部001中各角部001和与该角部001对应的多边形300的顶角301不交叠的区域N0的面积。
例如，图5示意性的示出多边形300的所有顶角均存在与对应的发光区200的相应的角部001不交叠的区域N0，但不限于此，还可以为多边形的部分顶角与发光区相应角部存在不交叠的区域，部分顶角与发光区相应角部完全交叠。
例如，如图4A和图5所示，至少两种不同颜色子像素中(例如第一颜色子像素和第二颜色子像素，或者第一颜色子像素和第三颜色子像素，或者第二颜色子像素和第三颜色子像素，或者第一颜色子像素、第二颜色子像素和第三颜色子像素)，发光区200的形状为多边形300截去至少一个第一顶角301后的形状，例如用于截去多边形300的第一顶角301的截线302可以包括曲线、直线等具有规则形状的线段，也可以为不规则形状的线段。
例如，本公开实施例示意性的示出多边形300为四边形，例如，对应于至少一种颜色子像素的多边形的形状可以为菱形、矩形或者正方形，但不限于此，多边形300 还可以为三角形、五边形或者六边形等，本公开实施例对此不作限制。例如，多边形的各顶角的角度可以相等，也可以不等。
如图4A、图4B和图5所示，发光区(或开口)101的顶角包括第一角部1011，第一角部1011为多边形300被截去由两条第一边310所夹的第一顶角301后形成的角部。例如，所述两条第一边310至少之一被截去的部分L1与第一边310的长度之比为0.2～0.8。多边形300的第一边310被截去第一线段L1后剩余部分L2形成连接第一角部1011的发光区200的边，例如第一角部1011的两端分别与发光区200的两条直边连接，这两条直边的至少一条直边为多边形300的第一边310截去第一线段L1后剩余的直线边。
例如，多边形300可以被截去至少一个第一顶角301以形成至少一个第一角部1011。例如，一个多边形300包括的多个第一顶角301度数相等，且该多个第一顶角301被截去后形成的多个第一角部1011的形状和尺寸等参数均相等。
第一线段L1的长度与第一边310的长度之比为0.2～0.8。例如，第一线段L1的长度与第一边310的长度之比为0.3～0.7；例如，第一线段L1的长度与第一边310的长度之比为0.4～0.6；例如，第一线段L1的长度与第一边310的长度之比为0.5。
例如，第一线段L1的长度与剩余部分L2的长度之比为0.25～4。例如，第一线段L1的长度与剩余部分L2的长度之比为1～3。第一线段L1的长度与剩余部分L2的长度之比为0.5～2。
例如，所述至少两种不同颜色子像素中的所述第一角部1011的数量不同。例如，两种不同颜色子像素中的第一角部1011的数量不同可以指：相同颜色子像素中的第一角部的数量相同，两个不同颜色子像素中，一个子像素中的第一角部的数量与另一个颜色不同的子像素中的第一角部的数量不同。例如，两种不同颜色子像素中的第一角部1011的数量不同还可以指：相同颜色子像素中的第一角部的数量相同，不同颜色子像素的数量不同，则不同颜色子像素包括第一角部的总数量不同。
例如，至少两种不同颜色子像素中的第一角部1011的数量不同，有利于调节至少部分显示区中的亮度中心以使其分布更均匀。
例如，如图4A所示，相同颜色的子像素的发光区200的面积相同，不同颜色子像素的发光区200的面积不同。
例如，在发光区200包括一个第一角部1011时，该发光区200的几何中心位于第一顶角301的顶点和与第一角部1011相对的顶角的顶点连线303的中点远离第一角部 1011的一侧，由此通过调节至少部分发光区的几何中心，可以调节至少部分显示区中的亮度中心以使其分布更均匀。
例如，如图4A和图5所示，本公开实施例提供的显示基板中，通过对部分子像素的形状进行调整，使得第一颜色子像素、第二颜色子像素和第三颜色子像素的至少两种颜色子像素中，与第一角部的两端连接的两条直边的延长线的交点到该子像素的发光区的几何中心的距离与构成与第一角部相对的发光区的顶角的两条直边或其延长线的交点到该子像素的发光区的几何中心的距离不同，以调整每个虚拟像素单元的实际亮度中心，使得该显示基板中各个实际亮度中心分布更加均匀。
例如，一种颜色子像素中的第一角部1011的数量为一个，另一种颜色子像素的第一角部1011的数量大于一，例如可以为两个，三个或者四个。例如，一种颜色子像素中的第一角部1011的数量可以为两个，另一种颜色子像素中的第一角部1011的数量可以为三个或者四个。例如，一种颜色子像素中的第一角部1011的数量可以为三个，另一种颜色子像素中的第一角部1011的数量可以为四个，本公开实施例对于不同颜色子像素的第一角部的数量不作限制，可根据实际产品需求进行设置。
例如，第一角部1011包括一顶点P1，该顶点可以在连线303上，与第一角部1011的两端连接的两条边向其顶点P1延伸交汇的部分形成的一段曲线(即第一角部的外侧边缘)以使得该第一角部1011成为圆倒角，此时，该第一角部1011可为从该顶点P1为中心沿轮廓x微米的范围，x的值可以为2～7微米。在第一角部为圆倒角，发光区的形状中与第一角部相对的顶角为直角或锐角时，与第一角部的两端连接的两条直边的延长线的交点到该发光区200的几何中心O1的距离大于构成与第一角部相对的顶角的两条直边的延长线的交点到该几何中心O1的距离。
上述“圆倒角”为一段曲线形成的顶角，该曲线可以为圆弧，也可以为非规则的曲线，例如椭圆形中截取的曲线、波浪线等。本公开实施例示意性的示出该曲线具有相对于发光区200的几何中心O1向外凸的形状，但不限于此，该曲线也可以具有相对于发光区200的几何中心O1向内凹的形状。例如，曲线为向外凸的圆弧时，该圆弧的圆心角的范围可以为10°～150°。例如，该圆弧的圆心角的范围可以为60°～120°。例如，该圆弧的圆心角的范围可以为90°。例如，第一角部1011包括的圆倒角的曲线长度可以为10～60微米。
例如，第一角部1011为圆倒角时，其曲率半径可以为5～20微米。
参照图4A，对于所述多个子像素中的至少一些子像素(例如至少部分第三颜色子 像素SP3)而言，每一个子像素的阳极结构在所述衬底基板上的正投影的图形与该子像素的开口在所述衬底基板上的正投影的图形具有不同数量的对称轴线。在图4A所示的实施例中，对于所述多个子像素中的至少一些子像素(例如至少部分第三颜色子像素SP3)而言，每一个子像素的阳极结构在所述衬底基板上的正投影的图形的对称轴线的数量大于该子像素的开口在所述衬底基板上的正投影的图形的对称轴线的数量。例如，第三颜色子像素SP3的开口103在所述衬底基板上的正投影的图形具有1条对称轴线，第三颜色子像素SP3的阳极结构在所述衬底基板上的正投影的图形具有至少2条对称轴线。在图8A所示的实施例中，例如，第三颜色子像素SP3的开口103在所述衬底基板上的正投影的图形具有1条对称轴线，第三颜色子像素SP3的阳极结构在所述衬底基板上的正投影的图形具有无穷条对称轴线。
例如，如图4A和图8A所示，第三子像素SP3包括4种类型，为了描述方便，分别称为第一类型子像素1001、第二类型子像素1002、第三类型子像素1003和第四类型子像素1004。在第一类型子像素1001、第二类型子像素1002、第三类型子像素1003和第四类型子像素1004中，第一角部1011的顶点指向第二角部1012的顶点的方向分别为方向D2、方向D3、方向D4和方向D1。例如，第一类型子像素1001的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D2；第二类型子像素1002的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D3；第三类型子像素1003的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D4；第四类型子像素1004的开口中，第一角部1011的顶点指向第二角部1012的顶点的方向为方向D1。
在本文中，为了方便描述，将第一类型子像素1001具有的开口称为第一类型开口，将第二类型子像素1002具有的开口称为第二类型开口，将第三类型子像素1003具有的开口称为第三类型开口，将第四类型子像素1004具有的开口称为第四类型开口，以此类推。
参照图4A和图8A，对于至少一个第一类型开口而言，在第一排列方向X上与该第一类型开口相邻的两个开口为第二类型开口，在第二排列方向Y上与该第一类型开口相邻的两个开口为第二类型开口，在第一方向M1上与该第一类型开口相邻的两个开口为第三类型开口，在第二方向M2上与该第一类型开口相邻的两个开口为第四类型开口。

所述第三类型开口和所述第四类型开口中的至少一个在所述衬底基板1上的正投影的图形仅相对于沿第一排列方向X延伸的第二对称轴线AX2对称。覆盖所述第三类型开口和所述第四类型开口的各个阳极结构413在所述衬底基板1上的正投影的图形相对于沿第一排列方向X延伸的第二对称轴线AX2和沿第二排列方向X延伸的第一对称轴线AX1均对称。
对于所述多个子像素中的至少一些子像素而言，每一个子像素的阳极结构在所述衬底基板上的正投影的图形的几何中心与该子像素的开口在所述衬底基板上的正投影的图形的几何中心不重合。例如，结合参照图4A、图4B、图5、图8A和图8B，对于至少一些第三颜色子像素SP3而言，第三颜色子像素SP3的阳极结构403在所述衬底基板上的正投影的图形为规则图形，例如，该规则图形为矩形、圆角矩形或圆形。在此情况下，第三颜色子像素SP3的阳极结构403在所述衬底基板上的正投影的图形的几何中心O2为矩形的2条对角线的交点。第三颜色子像素SP3的阳极结构403在所述衬底基板1上的正投影的图形的几何中心O2与该子像素的开口103在所述衬底基板1上的正投影的图形的几何中心O1不重合。

参照图10A和图10B，对于所述多个子像素中的至少一些子像素而言，所述开口在衬底基板上的正投影呈多边形，所述阳极结构在衬底基板上的正投影呈矩形。例如， 对于所述多个子像素中的至少一些子像素而言，每一个子像素的开口在所述衬底基板上的正投影的图形为多边形500，例如五边形，所述多边形具有第一顶角501和第一边502，所述第一边502与所述第一顶角501相对。所述每一个子像素的阳极结构在所述衬底基板上的正投影的图形为矩形。
