本公开的实施例提供一种显示基板以及显示装置。显示基板包括：多个子像素，包括多个第一颜色子像素、多个第二颜色子像素以及多个第三颜色子像素。多个第一颜色子像素和多个第三颜色子像素沿行方向和列方向均交替设置以形成多个第一像素行和多个第一像素列，多个第二颜色子像素沿行方向和列方向均阵列排布以形成多个第二像素行和多个第二像素列，多个第一像素行和多个第二像素行沿列方向交替设置且在行方向上彼此错开，多个第一像素列和多个第二像素列沿行方向交替设置且在列方向上彼此错开。所述多个子像素包括多个发光区，各个发光区的每条边或其延长线依次连接形成多边形，且至少部分子像素的所述多边形的多个顶角存在与对应的发光区的多个角部不交叠的区域；至少一个子像素的所述发光区的多个角部中，至少包括第一角部，所述第一角部和与其对应的所述多边形的顶角不交叠的区域面积大于至少部分其他角部中各角部和与该角部对应的多边形的顶角不交叠的区域面积。本公开实施例通过在至少一个子像素中设置第一角部，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。
下面结合附图对本公开实施例提供的显示基板以及显示装置进行描述。
图1为根据本公开实施例的一示例提供的显示基板中像素排布的局部平面图。如图1所示，显示基板包括多个子像素100。如图1所示，多个子像素100包括多个第一颜色子像素110、多个第二颜色子像素120以及多个第三颜色子像素130。多个第一颜色子像素110和多个第三颜色子像素130沿行方向(如图1所示的X方向)交替设置以形成第一像素行01，多个第二颜色子像素120沿行方向排列以形成第二像素行02，第一像素行01和第二像素行02沿与行方向交叉的列方向(如图1所示的Y方向)交替设置且在行方向上彼此错开。例如，相邻的第一颜色子像素110和第二颜色子像素120沿第一方向排列，第一方向与行方向和列方向均相交。如图1所示，多个第一颜色子像素110和多个第三颜色子像素130沿列方向交替设置以形成多个第一像素列03，多个第二颜色子像素120沿行方向和列方向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沿行方向交替设置且在列方向上彼此错开，即一个第二颜色子像素120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120所在第二像素列04位于 相邻两个第一像素列03之间。
本公开实施例中，行方向和列方向均指第一颜色子像素和第三颜色子像素的排列方向，该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，行方向与列方向相交。例如，行方向与列方向之间的夹角可以为80-100度。例如，行方向与列方向之间的夹角可以为85-95度。例如，行方向和列方向可以垂直，但不限于此，也可以不垂直。本公开实施例中，行方向和列方向可以互换。
如图1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110、一个第三颜色子像素130和两个第二颜色子像素120，第一颜色子像素110和第三颜色子像素130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110、第一个重复单元中的第三颜色子像素130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120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110还与该重复单元中的第三颜色子像素130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120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130还与该重复单元中的另一个第二颜色子像素120以及第三个重复单元中的第一颜色子像素110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110和第三颜色子像素130为共用子像素，根据二者发光光谱，这两者的面积均大于第二颜色子像素120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。
如图1所示，每个子像素100包括发光区101。例如，图2为图1所示像素结构对应的部分像素限定层的平面结构示意图。如图1和图2所示，显示基板设置有像素限定层200，各子像素100的发光区101的形状由像素限定层200中的开口限定，则各子像素100的发光区101的形状与像素限定层200的开口的形状大致相同。
例如，如图1和图2所示，像素限定层200包括多个第一开口201、多个第二开口202以及多个第三开口203。第一开口201限定了第一颜色子像素110的第一发光区101-1，第二开口202限定了第二颜色子像素120的第二发光区101-2，第三开口203限定了第三颜色子像素130的第三发光区101-3。
例如，显示基板包括衬底基板，各子像素100以及像素限定层200设置在衬底基板上。各子像素100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，第二电极位于发光层面向衬底基板的一侧。例如，第二电极的至少部分位于像素限定层面向衬底基板的一侧。当发光层形成在上述像素限定层200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限定层200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。
本公开实施例示意性的示出像素限定层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，例如各子像素的第二电极(如阳极)的形状也可以为包括圆角的图形。像素限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，像素限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限定层的开口。例如，发光层的面积大于对应的像素限定层开口的面积，即发光层除位于像素限定层开口内部的部分，至少还包括覆盖像素限定层的实体结构上的部分。通常在像素限定层开口的各个边界处的像素限定层的实体结构上均覆盖发光层。
例如，彼此相邻的第一颜色子像素110和第三颜色子像素130的发光层在像素限定层200上可以交叠，也可以不交叠。例如，彼此相邻的第一颜色子像 素110和第二颜色子像素120的发光层在像素限定层200上可以交叠，也可以不交叠。例如，彼此相邻的第二颜色子像素120和第三颜色子像素130的发光层在像素限定层200上可以交叠，也可以不交叠。例如，在平行于XY面的方向，第一角部1011的顶点与发光层边界之间的最短距离小于其他顶角的顶点与发光层边界之间的最短距离。
图3为图1所示的一个发光区的形状示意图。如图1和图3所示，各个发光区101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101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101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3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101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1和图3所示，至少两种不同颜色子像素100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101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1和图3所示，发光区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101的边，例如第一角部1011的两端分别与发光 区101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。
如图1和图3所示，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，如图1和图3所示，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，如图1和图3所示，所述至少两种不同颜色子像素100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100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100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，如图1和图3所示，至少两种不同颜色子像素100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1所示，相同颜色的子像素100的发光区101的面积相同，不同颜色子像素100的发光区101的面积不同。
例如，在发光区101包括一个第一角部1011时，该发光区101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1和图3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100中的第一角部1011的数量为一个，另一种颜色子像素100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100中的第一角部1011的数量可以为两个，另一种颜色子像素100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100中的第一角部1011的数量可以为三个，另一种颜色子像素100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，如图1和图3所示，第一角部1011包括一顶点P，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P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P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101的几何中心O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O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101的几何中心O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101的几何中心O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。
例如，图4A为另一种发光区形状的示意图。如图4A所示，上述第一角部也可以为某一顶角的两条边向其顶点P延伸交汇的部分形成的线段(即第一角部的外侧边缘)以使得该顶角成为平倒角，例如第一角部1011包括平倒角，该第一角部的顶点可以在连线303上，例如为连线303与平倒角的交点。
例如，图4B为另一种发光区形状的示意图。如图4B所示，具有第一角部1011的发光区101的形状可以为扇形，其轮廓包括两条直边、连接两条直边的第一角部1011的弧线，以及两条直边相交形成的第二角部1012的顶点(或者连接两条直边的第二角部1012的弧线)。
例如，如图1至图4A所示，第一角部1011的外侧边缘的形状包括线段，不同颜色子像素100中的第一角部1011的外侧边缘的长度之比为0.8～1.2。例如，至少两种颜色子像素100中的第一角部1011的外侧边缘的长度之比为0.9～1.1。例如，至少两种颜色子像素100中的第一角部1011的外侧边缘的长度大致相等。例如，至少两种颜色子像素100中，第一角部1011与连线303的夹角相同。
例如，如图1至图4A所示，第一角部1011的外侧边缘的形状包括圆弧，不同颜色子像素100中的第一角部1011的外侧边缘的弧度之比为0.8～1.2。例如，至少两种颜色子像素100中的第一角部1011的外侧边缘的弧度之比为0.9～1.1。例如，至少两种颜色子像素100中的第一角部1011的外侧边缘的弧度大致相等。
例如，至少一种颜色子像素100中，连接第一角部1011的两个端点的发光区101的两条边的长度大致相等。
例如，如图1所示，第一颜色子像素110、第二颜色子像素120和第三颜色子像素130的发光区101均包括第一角部1011，且不同颜色子像素100中的第一角部1011的数量不同。
本公开实施例以同一颜色子像素中的第一角部的形状(包括长度以及曲率等参数)以及数量均相同，不同颜色子像素中的第一角部的形状相同为例进行描述，但不限于此，不同颜色子像素中的第一角部的形状可以相同，也可以不同。
例如，如图1所示，第一颜色子像素110包括四个第一角部1011，第二颜色子像素120包括两个第一角部1011，第三颜色子像素130包括一个第一角部1011。
例如，如图1至图4A所示，第一颜色子像素110、第二颜色子像素120和第三颜色子像素130的至少之一中，发光区101的顶角还包括第二角部1012，连接第一角部1011的两端点的两条边或其延长线的交点(即第一顶角301的顶点)到该子像素100的发光区101的几何中心O的距离大于构成第二角部 1012的两条边或其延长线的交点到几何中心O的距离。上述“构成第二角部1012的两条边”可以指这两条边相交形成了第二角部，也可以指这两条边与第二角部的两端连接。
例如，如图1至图4A所示，第二角部1012可以为多边形300没有截去顶角的角部，即第二角部1012可以为多边形300的一个顶角，该顶角可以与第一角部1011相对，也可以与第一角部1011相邻。
例如，如图1至图4A所示，第二角部1012可以为多边形300被截去由两条第二边320所夹的第二顶角304或由一条所述第一边310和一条第二边320所夹的第二顶角304后形成的角部，所述第一边310和所述第二边320至少之一被截去的部分L3与该边之比为0.05～0.2。多边形300的第二边320被截去第二线段L3后形成连接第二角部1012的发光区101的边(即剩余部分L4)，第二线段L3的长度与该边的长度之比为0.05～0.2。例如，第二线段L3的长度与该边的长度之比为0.08～0.18。例如，第二线段L3的长度与该边的长度之比为0.1～0.15。
例如，第二线段L3的长度与剩余部分L4的长度之比为0.05～0.3。例如，第二线段L3的长度与剩余部分L4的长度之比为0.1～0.2。
例如，如图1至图4A所示，第一边310和第二边320的长度可以相同，第一线段L1的长度大于第二线段L3的长度，则第一角部1011的曲率(或圆弧弧度或长度)大于第二角部1012的曲率(或圆弧弧度或长度)。
例如，如图1至图4A所示，第二角部1012的外侧边缘的形状包括线段，不同颜色子像素100中的第二角部1012的外侧边缘的长度之比为0.8～1.2。例如，至少两种颜色子像素100中的第二角部1012的外侧边缘的长度之比为0.9～1.1。例如，至少两种颜色子像素100中的第二角部1012的外侧边缘的长度大致相等。例如，至少两种颜色子像素100中，第二角部1012与连接该第二角部1012和与其相对顶角的顶点的连线的夹角相同。

例如，至少一种颜色子像素100中，连接同一个第二角部1012的两个端 点的发光区101的两条边的长度大致相等。
本公开实施例以同一颜色子像素中的第二角部的形状(包括长度以及曲率等参数)以及数量均相同，不同颜色子像素中的第二角部的形状相同为例进行描述，但不限于此，不同颜色子像素中的第二角部的形状可以相同，也可以不同。

例如，如图1至图4A所示，第一颜色子像素110、第二颜色子像素120和第三颜色子像素130的至少之一中，发光区101各边延长线的交点连线形成菱形，且菱形的对角线平行于行方向和列方向的至少之一。上述发光区101各边延长线交点连线形成了上述多边形。
例如，如图1至图4A所示，第一颜色子像素110、第二颜色子像素120和第三颜色子像素130的一种颜色子像素中，发光区100各边延长线的交点连线形成长条形，例如长方形，且长条形的长轴与行方向和列方向均相交。
例如，长条形的长轴与行方向之间的夹角可以为20-60度。例如，长条形的长轴与行方向之间的夹角可以为30-50度。
例如，图1示意性的示出各发光区101包括四个角部，对应于第一颜色子像素110和第三颜色子像素130的多边形的形状为菱形或者正方形，对应于第二颜色子像素120的多边形的形状为长方形。例如，第一颜色子像素110包括四个第一角部1011；第二颜色子像素120包括两个第一角部1011和两个第二角部1012，第二颜色子像素120中，第一角部1011的圆弧弧度大于第二角部1012的圆弧弧度；第三颜色子像素130包括一个第一角部1011和三个第二角部1012，第一角部1011的圆弧弧度大于第二角部1012的圆弧弧度，但本公开实施例不限于此。

例如，至少部分子像素还包括像素电路(图7A和图7B所示的像素电路700)，像素电路被配置为与发光元件连接以驱动发光元件发光。显示基板上的至少部分区域中设置了一些子像素，这些子像素的像素电路沿行方向和列方向阵列分布，被同一行像素电路驱动发光的子像素为位于同一行的子像素(包括位于同一行的第一颜色子像素和第三颜色子像素，或者位于同一行的第二颜色子像素)，被同一列像素电路驱动发光的子像素为位于同一列的子像素。
例如，显示基板还包括沿行方向延伸且沿列方向排布的多条栅线，被同一条栅线控制的子像素为位于同一行的子像素。
例如，沿行方向排列的第一颜色子像素和第二颜色子像素的发光区可以被一条沿行方向延伸的直线穿过，该直线可以穿过至少部分子像素的发光区的几何中心。例如，沿行方向排列的第二颜色子像素的发光区也可以被一条沿行方向延伸的直线穿过，该直线可以穿过至少部分子像素的发光区。同理，沿列方向排列的一列子像素的发光区可以被一条沿列方向延伸的直线穿过，该直线可以穿过至少部分子像素的发光区的几何中心。
例如，如图1所示，上述“一子像素”可以为第三颜色子像素130，上述“另一种颜色子像素”可以为第一颜色子像素120，第三颜色子像素130包括一个第一角部1011，第一颜色子像素110的发光区101的顶角均为第一角部1011， 由于第三颜色子像素130中设置了一个第一角部1011而使得该子像素的发光区的几何中心相对于没有设置第一角部1011时向远离该第一角部1011的方向偏移，而第一颜色子像素110中的顶角均为第一角部1011，其发光区的几何中心相对于没有设置第一角部1011的情况没有偏移，则沿行方向和列方向之一的方向排列的这两种颜色子像素的几何中心连线不再为直线，而是为折线。当然，本公开实施例不限于“一子像素”为第三颜色子像素，还可以为第一颜色子像素，则相应的，上述“另一种颜色子像素”为第一颜色子像素。
例如，如图1所示，上述“一子像素”中包括的第一角部的数量可以为多个，但是不能均位于相对的角，即上述包括第一角部的“一子像素”相对于该子像素没有设置第一角部时，其发光区的几何中心是发生了偏移的，例如其几何中心向远离第一角部的方向偏移的。
例如，图4C为图1所示的部分子像素的发光区的示意图。如图4C所示，所述第一颜色子像素110的所述发光区的每条边或其延长线顺次连接形成第一多边形300-1，所述第二颜色子像素120的每条边或其延长线顺次连接形成第二多边形300-2，所述第三颜色子像素130的发光区的每条边或其延长线顺次连接形成第三多边形300-3，所述第一多边形300-1、所述第二多边形和300-2所述第三多边形300-3中的至少两个为相似图形。例如，第一多边形300-1和第三多边形300-3为相似图形。本公开实施例不限于此，还可以第一多边形和第二多边形为相似图形；或者第二多边形和第三多边形为相似图形；或者三者均为相似图形。
例如，如图1和图4C所示，在同一个所述子像素100中，连接所述第一角部1011两端的两条直边SL的最短距离d11不大于该子像素100中与所述第一角部1011相邻的两个角部的顶点之间连线L的长度。
例如，如图1和图4C所示，连接所述第一角部1011两端的所述两条直边SL的长度均不小于3微米。例如，连接所述第一角部1011两端的所述两条直边SL的长度均不小于4微米。连接所述第一角部1011两端的所述两条直边SL的长度均不小于5微米。
例如，如图1和图4C所示，具有所述第一角部1011的至少一个子像素100的发光区101为轴对称图形，且所述轴对称图形中的至少一个对称轴AS与所述第一角部1011的平分线AB重合。
图5为根据本公开实施例的另一示例提供的显示基板中像素排布的局部平 面图。如图5所示，第三颜色子像素130和第二颜色子像素120均包括一个第一角部1101，第一颜色子像素110包括三个第一角部1101。当然，本公开实施例对包括一个第一角部的子像素的颜色不作限制，可以为红色子像素、绿色子像素或者蓝色子像素；本公开实施例对包括三个第一角部的子像素的颜色不作限制，可以为红色子像素、绿色子像素或者蓝色子像素。
例如，如图5所示，各子像素100中的第二角部1012可以为由相邻两直边相交形成顶角，也可以为圆倒角或者直倒角，本公开实施例对此不作限制。例如，如图5所示，不同颜色子像素中的第二角部1012的形状可以相同，也可以不同。
在各发光区的顶角的数量为四个时，本公开实施例对不同颜色子像素包括的第一角部的数量不作限制，可以三种颜色子像素包括的第一角部的数量均不相同，该数量可以从1-4中选择3个；也可以是两种颜色子像素包括的第一角部的数量相同，第三种颜色子像素包括的第一角部的数量不同，则两种颜色子像素包括的第一角部的数量可以从1-4中选择1个，第三种颜色子像素包括的第一角部的数量可以从1-4中选择另一个；也可以是只有两种颜色子像素包括第一角部，则不同颜色子像素包括的第一角部的数量可以从1-4中选择2个，本公开实施例可以根据产品的需要进行设置。
当然，本公开实施例不限于各发光区的顶角的数量为四个，还可以为三个或大于四个，此时，子像素中第一角部的数量可以按照上述规律进行设置。
例如，第一颜色子像素110、第二颜色子像素120和第三颜色子像素130中的至少一种颜色子像素中，各发光区101包括第一角部1011和第二角部1012，第二角部1012包括与第一角部1011相对的顶角。上述至少一种颜色子像素包括同一种类型子像素，该类型子像素中，第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向均相同。
例如，图6A为根据本公开实施例的一示例提供的显示基板中像素排布的局部平面图。如图6A所示，第三颜色子像素130包括同一种类型子像素，该类型子像素中，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D1均与X方向的箭头所指的方向相反，例如方向D1指向左，第一角部1011朝向右。例如，沿Y方向排列且相邻的第一像素列和第二像素列中的一列第一颜色子像素110和一列第二颜色子像素120在发光时容易形成波浪线，通过将第三颜色子像素130设置为其第一角部1011均朝向右，可以调节亮度 中心，减弱锯齿现象，有利于改善显示基板的显示效果。
本公开实施例不限于此，该同一种类型子像素中，第一角部的顶点指向与其相对的第二角部的顶点的方向还可以均与X方向的箭头所指的方向相同，例如方向D1指向右，第一角部朝向左；或者，该同一种类型子像素中，第一角部的顶点指向与其相对的第二角部的顶点的方向还可以均与Y方向的箭头所指的方向相同，例如方向D1指向上，第一角部朝向下；或者，该同一种类型子像素中，第一角部的顶点指向与其相对的第二角部的顶点的方向还可以均与Y方向的箭头所指的方向相反，例如方向D1指向下，第一角部朝向上。例如，沿X方向排列且相邻的第一像素行和第二像素行中的一行第一颜色子像素110和一行第二颜色子像素120在发光时容易形成波浪线，通过将第三颜色子像素130的第一角部1011均朝上或者朝下，可以调节亮度中心，减弱锯齿现象，有利于改善显示基板的显示效果。
例如，如图6A所示，第三颜色子像素130中的该类型子像素中的第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向可以平行于行方向或者列方向。
本公开实施例不限于各行或者各列第三颜色子像素的第一角部的朝向相同，例如，多个第一像素行中的至少之一中，第三颜色子像素130中的第一角部1011的朝向相同；或者，多个第一像素列中的至少之一中，第三颜色子像素130中的第一角部1011的朝向相同。例如，分别位于不同第一像素行(或不同第一像素列)中的第三颜色子像素130的第一角部1011的朝向可以相同，也可以不同，可以根据实际产品需求进行设置。
本公开实施例不限于第三颜色子像素中的第一角部均朝向同一方向，例如，还可以第二颜色子像素中的第一角部均朝向同一方向，或者第一颜色子像素中的第一角部均朝向同一方向，或者至少两种颜色子像素中的第一角部均朝向同一方向。
例如，如图6A所示，显示基板包括多个子像素组2000，至少一个子像素组2000包括沿行方向和列方向之一排列且相邻的一个第一颜色子像素110和一个第三颜色子像素130以及沿行方向和列方向的另一个排列且相邻的两个第二颜色子像素120，两个第二颜色子像素120中心连线与另外两个子像素中心连线相交，且两个第二颜色子像素120相对于另外两个子像素中心连线对称分布。例如，第二颜色子像素120为绿色子像素，在子像素组2000中的两个第 二颜色子像素120对称分布，有利于提高显示基板上绿色子像素分布的均匀性。
例如，如图6A所示，至少一个第二子像素组2000中，第三颜色子像素130的四个角部包括至少一个第一角部1011，至少一个第一角部1011包括第三颜色子像素130中最远离第一颜色子像素110的顶角，有利于将第三颜色子像素130的中心调节为靠近第一颜色子像素110，提高显示基板的亮度均匀性。
例如，图6A示意性的示出，在各子像素组2000中，第三颜色子像素130包括一个第一角部1011，且该第一角部1011为第三颜色子像素130中最远离与其在行方向相邻的第一颜色子像素110的顶角，即该第一角部1011朝右或者朝左。
本公开实施例不限于此，例如，第三颜色子像素的第一角部也可以均朝上或者均朝下，以使得第三颜色子像素的第一角部位于远离分布在第三颜色子像素在列方向上相邻的第一颜色子像素，以调节亮度中心。
例如，在至少一个子像素组2000中，第三颜色子像素130包括多个第一角部1011时，第一角部1011可以为除最靠近第一颜色子像素110的顶角以外的任一顶角。
例如，图6B为根据本公开实施例提供的一种子像素组的示意图。如图6B所示，至少一个子像素组2000中，第一颜色子像素110也可以包括至少一个第一角部1011，该至少一个第一角部1011可以包括最远离第三颜色子像素130的顶角，有利于调节亮度中心。
例如，如图6B所示，至少一个子像素组2000中，第二颜色子像素120可以包括至少一个第一角部1011，该第一角部1011的位置以及数量可以根据显示基板的亮度需求进行设置，例如第二颜色子像素120中的第一角部1011设置在朝向第一颜色子像素110的一侧，也可以设置在朝向第三颜色子像素130的一侧，还可以设置在远离第一颜色子像素110且远离第三颜色子像素130的一侧。例如，第二颜色子像素120可以设置两个第一角部1011，两个第一角部1011为发光区的相邻的两个顶角。例如，第二颜色子像素120还可以设置三个第一角部1011或者四个第一角部1011。
例如，第一颜色子像素110、第二颜色子像素120和第三颜色子像素130中的至少一种颜色子像素包括至少两种类型子像素，不同类型子像素中，第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向不同。
本公开实施例中不同类型子像素指第一角部的顶点指向与其相对的第二 角部的顶点的方向不同的子像素。例如，上述子像素可以包括一个第一角部和三个第二角部，三个第二角部之一与一个第一角部相对；上述子像素还可以包括两个第一角部和两个第二角部，每个第一角部和一个相应的第二角部相对，此时两个第一角部为相邻的顶角，根据该两个第一角部的相对位置关系而将其中一个第一角部作为判定不同类型子像素的基准第一角部，以该基准第一角部指向与其相对的第二角部的方向作为基准方向；上述子像素还可以包括三个第一角部和一个第二角部，以与第二角部相对的第一角部为基准第一角部来判定不同类型子像素，并以该基准第一角部指向与其相对的第二角部的方向作为基准方向。
例如，如图6B所示，在至少一种颜色子像素的发光区中，除上述基准第一角部和与其相对的第二角部外的其他两个顶角的顶点的连线L将该发光区分为两个部分，一个部分为第一角部所在的部分，另一个部分为第二角部所在的部分。例如，在同一个所述子像素中，与所述第一角部1011相邻的两个角部的顶点之间的连线L将所述子像素分成两部分，所述两部分面积不同。
例如，所述两部分面积比例为0.1-10。例如，所述两部分面积比例为0.2-9。例如，所述两部分面积比例为0.3-8。例如，所述两部分面积比例为0.4-7。例如，所述两部分面积比例为0.5-6。例如，所述两部分面积比例为0.7-5。
例如，第一角部1011所在部分的面积与第二角部1012所在部分的面积之比可以为0.1～0.99。例如，第一角部1011所在部分的面积与第二角部1012所在部分的面积之比可以为0.2～0.9。例如，第一角部1011所在部分的面积与第二角部1012所在部分的面积之比可以为0.3～0.8。例如，第一角部1011所在部分的面积与第二角部1012所在部分的面积之比可以为0.4～0.7。
例如，如图6B所示，第一角部1011的顶点与连线L之间的距离d1小于第二角部1012的顶点与连线L之间的距离d2。例如第一角部1011的顶点和连线L之间的距离d1与第二角部1012的顶点与连线L之间的距离d2之比d1/d2的范围可以为0.1～0.9。例如，d1/d2的范围可以为0.2～0.8。例如，d1/d2的范围可以为0.4～0.6。例如，d1与d2之比的范围可以为0.7～0.9。
例如，如图6B所示，第一角部1011的顶点与第二角部1012的顶点之间的连线的长度可以为a(即上述距离d1与距离d2之和)，连线L的长度可以为b，a与b之比的范围可以为0.6～0.9。例如，a与b之比的范围可以为0.7～0.8。
一般显示基板中，各子像素中彼此相对的两个顶角所在的两个部分的形状 和面积均相同，相对于这种显示基板，本公开提供的显示基板通过减小第一角部所在部分的面积，可以在该显示基板应用于具有屏下指纹功能或者屏下摄像头功能的显示装置时，有效提升显示基板的透光率。

例如，如图1所示，第一颜色子像素110和第二颜色子像素120沿第一斜向方向交替排列为第一组，第三颜色子像素130和第二颜色子像素120沿该第一斜向方向交替排列为第二组，第一组和第二组沿第二斜向方向交替排列。第一斜向方向和第二斜向方向彼此相交，且均与行方向和列方向相交。例如，沿第一斜向方向排列的至少一种颜色子像素可以包括至少一种类型子像素，沿第二斜向方向排列的至少一种颜色子像素可以包括至少一种类型子像素。例如，沿上述至少一种斜向方向排列的同一种颜色子像素可以包括四种不同类型子像素，以有利于改善显示基板在进行斜线等细节显示时出现的色偏问题。
例如，如图1至图8所示，至少部分第二颜色子像素120的四个角部包括至少一个第一角部1011，第二颜色子像素120包括第五类型子像素1005、第六类型子像素1006、第七类型子像素1007以及第八类型子像素1008，不同类型子像素中，第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向不同。对于第二颜色子像素中基准第一角部的选择以及不同类型子像素的定义与上述选择方式以及不同类型子像素的定义相同，在此不再赘述。
例如，如图1至图8所示，第五类型子像素1005、第六类型子像素1006、第七类型子像素1007以及第八类型子像素1008中，第一角部1011的顶点指向与其相对的第二角部1012的顶点的方向分别为第一方向P1、第二方向P2、第三方向P3以及第四方向P4，第一方向P1、第二方向P2、第三方向P3和第四方向P4均与行方向和列方向相交。例如，第一方向P1与第四方向P4相反，第二方向P2与第三方向P3相反。
例如，如图1和图8所示，多个第二像素行02包括沿列方向交替设置的第三子像素行021和第四子像素行022，第三子像素行021包括沿行方向交替设置的第五类型子像素1005和第六类型子像素1006，第四子像素行022包括沿行方向交替设置的第七类型子像素1007和第八类型子像素1008。例如，每个第二像素行02中同一种颜色子像素包括两种类型子像素，且这两种类型子 像素中第一角部1011的朝向相交，分别位于相邻第二像素行02中的两个第一角部1011的朝向可以相反，也可以相交。
例如，如图1和图8所示，多个第二像素列04包括沿行方向交替设置的第三子像素列041和第四子像素列042，第三子像素列041包括沿列方向交替设置的第五类型子像素1005和第七类型子像素1007，第四子像素列042包括沿列方向交替设置的第六类型子像素1006和第八类型子像素1008。例如，每个第二像素列04中同一种颜色子像素包括两种类型子像素，且这两种类型子像素中第一角部1011的朝向相交，分别位于相邻第二像素列04中的两个第一角部1011的朝向可以相反，也可以相交。
例如，如图1所示，显示基板包括多个子像素组1000，多个子像素组1000沿行方向排列为多个第一子像素组行1-1，且沿列方向排列的相邻第一子像素组行1-1沿行方向彼此错开。例如，沿列方向排列的相邻第一子像素组行1-1沿行方向彼此错开一个子像素组1000的节距。
例如，如图1所示，至少部分子像素组1000被一圈交替设置的第一颜色子像素110和第二颜色子像素120围绕。例如，沿行方向排列的相邻两个子像素组1000的彼此最靠近的两个子像素100之间设置有一个第一颜色子像素110，沿列方向排列的相邻两个子像素组1000的彼此最靠近的两个子像素100之间设置有一个第一颜色子像素110。
例如，如图1所示，各子像素组1000包括一个第一颜色子像素110、围绕第一颜色子像素110的四个第二颜色子像素120以及围绕第一颜色子像素110的四个第三颜色子像素130，第三颜色子像素130和第二颜色子像素120中至少一种颜色子像素的第一角部1011均朝向第一颜色子像素110。例如，第三颜色子像素130和第二颜色子像素120中的第一角部1011均朝向第一颜色子像素110。例如，各子像素组1000中位于边缘的顶角均不是第一角部1011，上述子像素组1000的排布为类似三阶魔方(Magic)结构。
例如，如图1所示，至少部分子像素组1000中，第一颜色子像素110的四个角部均为第一角部1011，第二颜色子像素120的四个角部包括两个第一角部1011，第三颜色子像素130和第二颜色子像素120的第一角部1011均朝向第一颜色子像素110。
例如，如图1和图5分别示出第二颜色子像素包括的第一角部的数量可以为一个或者两个，但不限于此，还可以不包括第一角部，或者包括三个或者四 个第一角部，且第二颜色子像素中第一角部的分布可以根据实际产品需求进行设置。
例如，图9为根据本公开实施例提供的另一种子像素组的示意图。图9所示子像素组1000与图1所示子像素组1000的不同之处在于，本示例中子像素组1000中的第二颜色子像素120的各边延长线的交点连线形成菱形。例如，该菱形的对角线平行于行方向和列方向的至少之一。例如，第二颜色子像素120的发光区的面积与第三颜色子像素130的发光区的面积比可以为0.8～1.2。例如，第二颜色子像素120的发光区的面积与第一颜色子像素的发光区的面积比可以为0.8～1.2。
例如，图9所示第二颜色子像素120的第一角部的分布规律可以与图1-图8所示第二颜色子像素120中第一角部的分布规律相同，在此不再赘述。图9所示其他颜色子像素的第一角部的分布规律可以与图1-图8所示其他颜色子像素的第一角部的分布规律相同，在此不再赘述。
例如，本公开实施例提供的显示基板中，第一颜色子像素、第二颜色子像素和第三颜色子像素中，可以有一种颜色子像素不包括第一角部，其他两种颜色子像素包括不同数量的第一角部。例如，不包括第一角部的子像素可以为红色子像素、绿色子像素或者蓝色子像素，本公开实施例对此不作限制。
例如，本公开实施例的一示例中，位于显示基板的显示区最边缘的子像素可以包括一行或一列交替排列的第一颜色子像素和第三颜色子像素，位于最边缘的该一行或一列子像素中的第一角部可以均朝向显示区的外侧，以防止显示基板在进行显示时，该边缘发生发紫的问题，且还有利于改善显示区边缘锯齿感。
例如，本公开实施例的一示例中，位于显示基板的显示区最边缘的子像素可以包括一行或一列第二颜色子像素，位于最边缘的该一行或一列第二颜色子像素中的第一角部可以均朝向显示区的外侧，以防止显示基板在进行显示时，该边缘发生发青的问题，且还有利于改善显示区边缘锯齿感。
本公开实施例不限于发光区中连接相邻顶角的边为直边，例如还可以为曲线边，例如向内凹或者向外凸的曲线边，则连接相邻顶角的边的长度也可以指曲线边的长度，该曲线边指圆倒角端点以外的部分。
例如，本公开实施例不限于第二颜色子像素的形状为矩形，还可以为椭圆形、橄榄形(如中间宽度款，两端宽度窄的形状)等形状。
本公开另一实施例提供一种显示装置，包括上述显示基板。
本公开实施例提供的显示装置中，至少两种不同颜色子像素中的第一角部的数量设置的不同，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，本公开实施例提供的显示装置可以为发光二极管显示装置。
例如，显示装置还可以包括位于显示基板显示侧的盖板。
例如，该显示装置可以为电视、数码相机、手机、手表、平板电脑、笔记本电脑、导航仪等任何具有显示功能的产品或者部件，本实施例不限于此。
例如，该显示装置可以为具有屏下摄像头的显示设备，该显示设备包括功能部件，例如包括相机模组(例如，前置摄像模组)、3D结构光模组(例如，3D结构光传感器)、飞行时间法3D成像模组(例如，飞行时间法传感器)、红外感测模组(例如，红外感测传感器)等至少之一。
有以下几点需要说明：
(1)本公开的实施例附图中，只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计。
(2)在不冲突的情况下，本公开的同一实施例及不同实施例中的特征可以相互组合。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
