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，下面将结合本公开实施例的附图，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它实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。
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。多个子像素包括多个第一子像素、多个第二子像素以及多个第三子像素；所述多个第一子像素和所述多个第三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，所述多个第二子像素沿所述行方向和所述列方向阵列排布以形成多个第二像素行和多个第二像素列，所述多个第一像素行和所述多个第二像素行沿所述列方向交替设置，所述多个第一像素列和所述多个第二像素列沿所述行方向交替设置；以位于同一所述第一像素行中相邻的一个所述第一子像素和一个所述第三子像素的中心，以及相邻的所述第一像素行中，沿所述列方向与该相邻的一个所述第一子像素和一个所述第三子像素分别相邻的一个所述第一子像素和一个所述第三子像素的中心为虚拟四边形的四个顶点，所述虚拟四边形内设置有一个第二子像素。所述多个子像素包括多个发光区，所述第一子像素、所述第二子像素和所述第三子像素的至少之一中，所述发光区的顶角包括相对设置的第一角部和第二角部，构成所述第一角部的两条边的延长线或两条边的切线的交点到该子像素的中心的距离大于构成所述第二角部的两条边或其延长线或两条边的切线的交点到该子像素的中心的距离；所述第一子像素、所述第二子像素和所述第三子像素中的至少之一包括第一类型子像素和第二类型子像素，不同类型子像素中，所述第一角部的顶点指向所述第二角部的顶点的方向不同，且所述第一类型子像素和所述第二类型子像素中，所述第一角部的顶点指向所述第二角部的顶点的方向分别为第一方向和第二方向，所述第一方向和所述第二方向相反。本公开实施例中， 通过将显示基板包括的第一子像素、第二子像素和第三子像素中的至少之一设置为包括两种不同类型的子像素，使得该显示基板进行显示时，有利于改善色偏问题。
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提供的显示基板的局部结构示意图。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包括多个第一子像素10、多个第二子像素20以及多个第三子像素30。多个第一子像素10和多个第三子像素30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，多个第二子像素20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，且多个第一子像素10和多个第三子像素30沿列方向交替设置。
例如，如图1所示，多个第一子像素10和多个第三子像素30沿行方向和列方向均交替排布以形成多个第一像素行01和多个第一像素列03，多个第二子像素20沿行方向和列方向阵列排布以形成多个第二像素行02和多个第二像素列04，行方向与列方向相交。例如，行方向和列方向可以垂直。行方向和列方向可以互换。
如图1所示，以第一像素行01中相邻的第一子像素10和第三子像素30的中心，以及沿列方向与该相邻的第一子像素10和第三子像素30分别相邻的第一子像素10和第三子像素30的中心为虚拟四边形101的四个顶点，虚拟四边形101内设置有一个第二子像素20。例如，第二子像素20与相邻第一像素行01中的第一子像素10和第三子像素30交错设置。
例如，上述子像素的中心例如为该子像素的几何中心，或者为该子像素的各个边的中垂线的交点，亦或者为该子像素中到各个边的垂直距离大致相等的点。当然，上述子像素的中心可以允许有一定的误差。例如，子像素的中心可以为以子像素的几何中心为圆心半径为3μm范围内的任何一个点。
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1个第一子像素10、1个第三子像素30和2个第二子像素20，第一子像素10和第三子像素30为共用子像素，通过虚拟算法，可以使得4个子像素实现2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子像素10、第一个重复单元中的第三子像素30以及第一个重复单元中靠近第二个重复单元的第二子像素20形成一个虚拟像素单元，同时第二个重复单元中的第一子像素10还与该重复单元中的第三子像素30以及与该重复单元中的靠近第一个重复单元的第二子像素20形成一个虚拟像素单元；另外，第二个重复单元中的第三子像素30还与该重复单元中的另一个第二子像素20以及第三个重复单元中的第一子像素10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1所示，在相邻角部通过直线边连接时，各子像素100包括发光区110。第一子像素10、第二子像素20和第三子像素30的至少之一中，发光区的顶角包括相对设置的第一角部111和第二角部112，构成第一角部111的两条直边的延长线的交点到该子像素的中心的距离与构成第二角部112的两条直边或其延长线的交点到该子像素的中心的距离不同。
例如，图2为图1所示一子像素的示意性放大图，如图2所示，构成第一角部111的两条直边L1和L2的延长线的交点到该子像素的中心O的距离与构成第二角部112的两条直边L3和L4的交点到该 子像素的中心O的距离不同。
本公开实施例中的子像素指发光器件结构，第一子像素、第二子像素和第三子像素为发出不同颜色光的子像素。本公开实施例以第一子像素为红色子像素，第二子像素为绿色子像素，第三子像素为蓝色子像素为例进行说明。但第一子像素为红色子像素，第二子像素为绿色子像素、第三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，第一子像素10和第三子像素30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子像素20面积。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，使得第一子像素、第二子像素和第三子像素的至少之一中，构成第一角部的两条直边的延长线的交点到该子像素的中心的距离与构成第二角部的两条直边或其延长线的交点到该子像素的中心的距离不同，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。
如图1所示，第一子像素10、第二子像素20和第三子像素30中的至少之一包括第一类型子像素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111的顶点指向第二角部112的顶点的方向不同。例如，不同类型子像素中第一角部111的位置不同。例如，不同类型子像素中第一角部111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、第二类型子像素、第三类型子像素以及第四类型子像素中，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和所述第二类型子像素的数量比为0.8～1.2，所述第三类型子像素和所述第四类型子像素的数量比为0.8～1.2。
如图1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111的顶点指向第二角部112的顶点的方向分别为第一方向D1、第二方向D2、第三方向D3和第四方向D4。例如，第一类型子像素1001的发光区中，第一角部111的顶点指向第二角部112的顶点的方向为第一方向D1；第二类型子像素1002的发光区中，第一角部111的顶点指向第二角部112的顶点的方向为第二方向D2；第三类型子像素1003的发光区中，第一角部111的顶点指向第二角部112的顶点的方向为第三方向D3；第四类型子像素1004的发光区中，第一角部111的顶点指向第二角部112的顶点的方向为第四方向D4。
如图1所示，第一方向D1和第二方向D2相反，且第三方向D3和第四方向D4相反。
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顶角的形状均相同，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。
例如，如图1所示，第一子像素10、第二子像素20以及第三子像素30的至少之一还包括相对设置的第三角部113和第四角部114，第三角部113的顶点和第四角部114的顶点的连线L将发光区划分为两部分，这两部分的形状不同，且第一角部111所在部分的面积小于第二角部112所在部分的面积。上述第三角部113的顶点和第四角部114的顶点的连线L将发光区分为第一部分和第二部分，第一角部为 第一部分中的角部，第二角部为第二部分中的角部，则第一角部所在部分指第一部分，第二角部所在部分指第二部分。
例如，第一角部111所在部分的面积与第二角部112所在部分的面积之比可以为0.1～0.95。例如，第一角部111所在部分的面积与第二角部112所在部分的面积之比可以为0.3～0.8。例如，第一角部111所在部分的面积与第二角部112所在部分的面积之比可以为0.4～0.7。
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，图2和图3为不同示例中第三类型子像素的示意性放大图。如图2和图3所示，上述顶角可以为两条线之间的夹角，例如第二角部112、第三角部113和第四角部114，例如三个角部可以均为直角或者锐角。例如，两条线的交点即为该角部的顶点，此时，该角部可为从该顶点为中心沿轮廓x微米的范围，x的值可以为2～7微米。如图2所示，上述顶角也可以为某一顶角的两条边向其顶点延伸交汇的部分形成的一段曲线以使得该顶角成为圆倒角，例如第一角部111包括圆倒角，该角部的顶点可以为用于形成上述圆倒角的两条边的延长线交点和与该圆倒角相对的顶角的顶点的连线与该圆倒角的交点P，此时，该角部可为从该顶点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，第二角部为直角或锐角时，构成第一角部的两条直边的延长线的交点到该子像素的中心的距离小于构成第二角部的两条直边的延长线的交点到该子像素的中心的距离。
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子像素的中心向外凸的形状，但不限于此，也可以为该曲线具有相对于子像素的中心向内凹的形状。例如，曲线为圆弧时，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111包括的圆倒角的曲线长度可以为10～60微米。
如图3所示，上述顶角也可以为某一顶角的两条边向其顶点延伸交汇的部分形成的线段以使得该顶角成为平倒角，例如第一角部111包括平倒角，该角部的顶点可以为用于形成上述平倒角的两条边的交点和与该平倒角相对的顶角的顶点的连线与该平倒角的交点P。
例如，图4A和图4B为不同示例中第三类型子像素的示意性放大图。如图4A所示，第一角部111、第二角部112、第三角部113以及第四角部114均包括圆倒角，且第一角部111的圆倒角的曲率半径大于第二角部112的圆倒角的曲率半径。例如，在上述四个角部均包括圆倒角时，各角部的顶点可以为用于形成上述圆倒角的两条边的延长线的交点和用于形成与该圆倒角相对的圆倒角的两条边的延长线的交点的连线与该圆倒角的交点，此时，各角部可为从该角部的顶点为中心沿轮廓x微米的范围，x的值可以为2～7微米。
例如，第一角部111的曲率半径可以用于形成该圆倒角的直边的长度的10％～70％。例如，第一角部111的曲率半径可以用于形成该圆倒角的直边的长度的20％～50％。
例如，第二角部112和第三角部113的顶点之间的连线的长度可以为40微米。例如，第一角部111的曲率半径可以为5～20微米。例如，第二角部112的曲率半径小于5微米。
例如，第一角部111的圆倒角的曲率半径大于其他三个角部的圆倒角的曲率半径。
例如，如图4B所示，与图4A所示第三类型子像素的不同之处在于连接相邻角部的边为曲线边而非直边。本示例中各角部的定义以及角部中顶点的定义与图4A所示示例中相同。图4B所示示例中，在相邻角部通过曲线边连接时，各子像素100包括发光区110。第一子像素10、第二子像素20和第三子像素30的至少之一中，发光区的顶角包括相对设置的第一角部111和第二角部112，构成第一角部111的两条边的切线的交点到该子像素的中心的距离与构成第二角部112的两条边的切线的交点到该子像素的中心的距离不同。
例如，图5为限定显示基板的像素限定层的平面结构示意图。如图1和图5所示，各子像素100的发光区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5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限定了第一子像素10的第一发光区110-1，第二开口202限定了第二子像素20的第二发光区110-2，第三开口203限定了第三子像素30的第三发光区110-3。
例如，各子像素100包括层叠设置的第一电极、发光层以及第二电极，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四边形，则各子像素的发光区的形状也为四边形，该四边形包括四个顶角。但不限于此，各子像素的发光区的形状还可以为三角形、五边形或六边形等形状，则发光区包括的顶角的数量也随之变化。
例如，如图1所示，第三角部113和第四角部114至少之一的形状与第二角部112的形状大致相同。例如，第二角部112、第三角部113和第四角部114的形状大致相同。上述“第二角部112、第三角部113和第四角部114的形状大致相同”是指例如这三者的角度相同、轮廓相同、大小相同、圆角的曲率相同等。
例如，如图1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以及第四类型子像素1004的形状和大小基本相同，其中三种类型子像素通过旋转一定角度后可以与第四种类型子像素的第一角部的朝向相同。这里第一角部的朝向可以指第一角部的顶点指向第二角部的顶点的方向。
例如，如图1所示，第一角部111的顶点与连线L之间的距离d1小于第二角部112的顶点与连线L之间的距离d2。例如第一角部111的顶点和连线L之间的距离d1与第二角部112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1所示，第一角部111的顶点与第二角部112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)，第三角部113的顶点与第四角部114的顶点之间的连线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。
例如，如图1和图5所示，显示基板包括衬底基板，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，彼此相邻的第一子像素10和第三子像素30的发光层在像素限定层200上可以交叠，也可以不交叠。例如，彼此相邻的第一子像素10和第二子像素20的发光层在像素限定层200上可以交叠，也可以不交叠。例如，彼此相邻的第二子像素20和第三子像素30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111的顶点与发光层边界之间的最短距离小于第二角部112的顶点与发光层边界之间的最短距离。例如，第一角部111的顶点与发光层边界之间的最短距离小于其他三个角部的顶点与发光层边界之间的最短距离。
例如，如图1所示，第一方向D1和第三方向D3之一平行于行方向，另一个平行于列方向。图1示意性的示出第三方向D3和第四方向D4平行于行方向，第一方向D1和第二方向D2平行于列方向，但不限于此，第一方向和第三方向的位置关系可以互换。
例如，以图1所示的X方向的箭头所指的方向为向右，Y方向的箭头所指的方向为向上，则第一类型子像素1001的第一角部111位于该子像素的下侧，第二类型子像素1002的第一角部111位于该子像素的上侧，第三类型子像素1003的第一角部111位于该子像素的左侧，第四类型子像素1004的第一角部111位于该子像素的右侧。
例如，如图1所示，行方向和列方向之间的夹角为80°-100°。例如，第一方向D1与第三方向D3之间的夹角为80°-100°。例如，第一方向D1与第三方向D3之间的夹角为85°-95°。例如，第一方向D1与第三方向D3之间的夹角为90°，即第一方向D1与第三方向D3垂直。
本公开实施例中，将各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设置为平行于行方向或者列方向，可以在保证各子像素开口率的同时，有利于改善整个显示基板显示时的色偏问题。
例如，如图1所示，至少一个第一像素行01包括多个第一像素组010，各第一像素组010包括八个子像素，且各第一像素组010包括第一类型子像素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。例如，显示基板包括至少一个显示区，位于显示区非边缘位置处的各第一像素行01包括多个第一像素组010。例如，显示基板中各第一像素行01包括多个第一像素组010。

例如，如图1所示，第一子像素10的发光区110-1的发光区形状包括多个顶角，各顶角的形状大致相同，第三子像素30的顶角与第一子像素10的顶角彼此相对。例如，第一子像素10和第三子像素30的发光区的形状均为四边形，即均包括四个顶角，则第三子像素30包括的各类型子像素的四个角部分别与围绕第三子像素30的四个第一子像素10的四个顶角相对。

例如，如图9所示，围绕各第三子像素30的四个第一子像素10分别为第一类型子像素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。
本公开实施例中，通过将围绕第三子像素的四个第一子像素设置为包括四种不同类型子像素，对于显示包括子像素数量较少的细节图像等，可以有利于降低色偏，且均一化视觉效果。
当然，在第一子像素包括四种类型子像素时，四种类型子像素的排布规律不限于图9所示的像素排布，还可以如图1、图6或图8等所示的显示基板中的第三子像素包括的四种类型子像素的排布规律，本公开实施例对此不作限制。

本示例中，第一子像素各角部与相邻第三子像素中相应角部之间距离的大小关系可以与图1所示示例中第三子像素中各角部与相邻第一子像素中相应角部之间距离的大小关系相同，在此不再赘述。
例如，图10为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图。如图10所示示例提供的显示基板与图1-图9所示示例提供的显示基板的不同之处在于第一子像素10和第三子像素30均包括第一类型子像素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。

例如，如图10所示，第一像素组010和第二像素组020均包括两个第一类型子像素1001、两个第二类型子像素1002、两个第三类型子像素1003和两个第四类型子像素1004。
例如，同一像素组中，第一子像素10包括的四种类型子像素的排列顺序与第三子像素30包括的四种类型子像素的排列顺序可以相同，也可以不同。

例如，如图10所示，第四像素组040可以包括两个第三子像素30和两个第二子像素20，两个第三子像素30包括两种类型子像素。
本示例提供的显示基板中，通过在行方向、列方向以及一个斜方向上分别设置包括上述四种不同类型子像素的第一像素组、第二像素组和第三像素组，在另一个斜方向上设置包括上述两种不同类型子像素的第四像素组，可以进一步改善显示基板在进行横线、竖线以及斜线等细节显示时出现的色偏问题。
例如，如图10所示，围绕各第三子像素30的四个第一子像素10分别为第一类型子像素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，且围绕各第一子像素10的四个第三子像素30分别为第一类型子像素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。
本公开实施例中，通过将围绕第三子像素的四个第一子像素设置为包括四种不同类型子像素，且将围绕第一子像素的四个第三子像素设置为包括四种不同类型子像素，对于显示包括子像素数量较少的细节图像等，可以有利于降低色偏，且均一化视觉效果。
当然，在第一子像素和第三子像素均包括四种类型子像素时，各子像素包括的四种类型子像素的排 布规律不限于图10所示的像素排布，各子像素包括的四种类型子像素的排布规律可以如图1、图6或图8等所示的显示基板中的第三子像素包括的四种类型子像素的排布规律，本公开实施例对此不作限制。
本示例中，第一子像素中各角部之间直边的长度关系可以与图1所示示例中第三子像素中各角部之间直边的长度关系相同；本示例中，第三子像素中各角部之间直边的长度关系可以与图1所示示例中第三子像素中各角部之间直边的长度关系相同，在此不再赘述。

例如，图1至图10所示的像素排列结构既可以位于显示基板的显示区的边缘，也可以位于显示基板的显示区非边缘，本公开实施例对此不作限制。
例如，本公开实施例不限于各第一像素行均包括第一像素组，和/或各第一像素列均包括第二像素组，至少一个第一像素行也可以包括四种类型子像素中的一种、两种或者三种，至少一个第一像素列也可以包括四种类型子像素中的一种、两种或者三种，本公开实施例对此不作限制，只要显示基板中包括的多个子像素包括上述四种类型子像素即可。
例如，图11为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图。如图11所示，显示基板包括至少一个显示区1000，图11示意性的示出显示基板包括的一个显示区，该显示区包括位于四周边缘的像素行和像素列。本公开实施例不限于此，显示基板还可以包括多个显示区，例如显示基板可以为折叠显示基板，根据折叠需求，显示基板可以包括两个显示区、四个显示区或者更多个显示区，各显示区均包括位于四周边缘的像素行和像素列。例如，在显示基板包括的两个显示区相邻时，两个显示区边缘的像素行或像素列也可以彼此相邻，虽然分别位于两个显示区的边缘的两个像素行或者两个像素列并没有位于显示基板的边缘，但是可以根据各显示区对边缘像素的需求进行相应的设计。
例如，如图11所示，位于至少一个显示区100最边缘且彼此相邻的第一像素行01和第二像素行02构成边缘像素行组012，例如各显示区1000可以包括两个边缘像素行组012；位于至少一个显示区1000最边缘且彼此相邻的第一像素列03和第二像素列04构成边缘像素列组034，例如各显示区1000可以包括两个边缘像素列组034。边缘像素行组012和边缘像素列组034的交叉位置设置有边角子像素102，边角子像素102包括第一子像素10和第三子像素30。例如，两个边缘像素行组012和两个边缘像素列组034交叉位置设置有四个边角子像素102，包括两个第一子像素10和两个第三子像素30。上述显示区最边缘指显示区能点亮的最边缘，而在显示区最边缘的边缘像素行组(和边缘像素列组)以外的位置可以设置虚设区(dummy区)，该虚设区不会被点亮。当然上述显示区最边缘也可以指最后一行(和最后一列)像素限定层的开口；以及第一行(和第一列)像素限定层的开口。
例如，如图11所示，边缘像素行组012中，除边角子像素102外的第一子像素10和第三子像素30的至少之一包括第一角部111和第二角部112，且第二角部112比第一角部111更靠近第二像素行02。例如，边缘像素行组012的第一像素行01中仅包括一种类型子像素，例如第二类型子像素1002。
一般显示基板中，各不同颜色子像素的发光区包括的四个顶角的形状均相同，则位于显示区上下边缘的两个像素行分别为红色子像素和蓝色子像素构成的一像素行以及绿色子像素构成的像素行，对于红色子像素和蓝色子像素构成的一像素行作为最边缘的像素行，该侧边缘在显示时容易出现发紫的问题；对于绿色子像素构成的像素行作为最边缘的像素行，该侧边缘在显示时容易出现发青的问题。此外，这种显示基板的发光区的边缘还可能因子像素的角部突出而导致显示时出现锯齿状边缘。
相对于这种显示基板的像素排列，本公开实施例提供的显示基板针对显示区的边缘像素行中子像素的形状进行改进，使得位于边缘像素行组中的蓝色子像素和红色子像素至少之一的第二角部位于第一角部靠近边缘像素行组中的绿色子像素行的一侧，从而使得蓝色子像素和红色子像素至少之一的亮度中心向绿色子像素偏移，以改善了边缘像素行出现发紫或发青的现象。此外，位于最边缘的像素行为蓝色子像素和红色子像素形成的第一像素行时，具有较长弧线长度的圆倒角作为位于边缘侧的第一角部，有利于改善边缘锯齿感。
例如，如图11所示，边缘像素列组034中，除边角子像素102外的第一子像素10和第三子像素30的至少之一包括第一角部111和第二角部112，且第二角部112比第一角部111更靠近第二像素列02。例如，边缘像素列组034中的第一像素列03中仅包括一种类型子像素，例如第三类型子像素1003。
一般显示基板中，各不同颜色子像素的发光区包括的四个顶角的形状均相同，则位于显示区左右边缘的两个像素列分别为红色子像素和蓝色子像素构成的一像素列以及绿色子像素构成的像素列，对于红色子像素和蓝色子像素构成的一像素列作为最边缘的像素列，该侧边缘在显示时容易出现发紫的问题；对于绿色子像素构成的像素列作为最边缘的像素列，该侧边缘在显示时容易出现发青的问题。此外，这种显示基板的发光区的边缘还可能因子像素的角部突出而导致显示时出现锯齿状边缘。
相对于这种显示基板的像素排列，本公开实施例提供的显示基板针对显示区的边缘像素列中子像素的形状进行改进，使得位于边缘像素列组中的蓝色子像素和红色子像素至少之一的第二角部位于第一角部靠近边缘像素列组中的绿色子像素列的一侧，从而使得蓝色子像素和红色子像素至少之一的亮度中心向绿色子像素偏移，以改善了边缘像素列出现发紫或发青的现象。此外，位于最边缘的像素列为蓝色子像素和红色子像素形成的第一像素列时，具有较长弧线长度的圆倒角作为位于边缘侧的第一角部，有利于改善边缘锯齿感。
例如，如图11所示，除了位于边缘像素行组012中的第一像素行01外，各第一像素行01均包括第一类型子像素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。例如，如图11所示，除了位于边缘像素列组034中的第一像素列03外，各第一像素列03均包括第一类型子像素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。
由此，本公开实施例提供的显示基板通过对第一子像素和第三子像素的至少之一的形状以及排布规律进行调整以调整亮度中心位置，既可以使得显示区非边缘区域内子像素的亮度中心分布更加均匀，进而改善色偏；还可以改善显示区边缘发紫或发青的现象以及边缘锯齿感。
例如，图11示意性的示出边缘像素行组和边缘像素列组均包括具有上述角部位置关系的子像素为例进行说明，但不限于此，还可以仅边缘像素行组或边缘像素列组包括具有上述角部位置关系的子像素。上述角部位置关系指“第一像素行组或第一像素列组中，第一子像素和第三子像素至少之一中的第一角部 和第二角部与第二像素行或第二像素列的位置关系”。
例如，如图11所示，边缘像素行组012中除边角子像素102外的第一子像素10和第三子像素30均包括第一角部111和第二角部112，且第二角部112均位于第一角部111靠近第二子像素行02的一侧；边缘像素列组034中除边角子像素102外的第一子像素10和第三子像素30均包括第一角部111和第二角部112，第二角部112均位于第一角部111靠近第二子像素列04的一侧。
例如，边缘像素行组中的第一像素行和边缘像素列组中的第一像素列均仅包括一种类型子像素，且边缘像素行组中包括的子像素的类型与边缘像素列组中包括的子像素的类型不同。例如，边缘像素行组中子像素的第一角部指向第二角部的方向与边缘像素列组中子像素的第一角部指向第二角部的方向相交。例如，边缘像素行组中子像素的第一角部指向第二角部的方向平行于列方向，边缘像素列组中子像素的第一角部指向第二角部的方向平行于行方向。
本公开实施例一示例通过将蓝色子像素和红色子像素均设置成具有上述角部位置关系的子像素以将边缘处的蓝色子像素和红色子像素的亮度中心均向绿色子像素偏移，可以更好的改善显示区边缘发紫或者发青的现象。上述角部位置关系指“第一像素行组或第一像素列组中，第一子像素和第三子像素至少之一中的第一角部和第二角部与第二像素行或第二像素列的位置关系”。
例如，如图11所示，边角子像素102中第一角部111指向第二角部112的方向可以与其所在的边缘像素行组012中的子像素中的第一角部111指向第二角部112的方向相同，也可以与其所在的边缘像素列组034中的子像素中的第一角部111指向第二角部112的方向相同，本公开实施例对此不作限制。
例如，图12为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图。图12所示示例与图11所示示例的不同之处在于位于边缘像素行组012和边缘像素列组034的至少之一中，仅第三子像素30中的第二角部112位于第一角部111靠近第二像素行02或第二像素列04的一侧，而位于边缘像素行组012和边缘像素列组034的至少之一中的第一子像素10包括四种类型子像素，即边缘像素行组012和边缘像素列组034的至少之一中，第一子像素10包括四种类型子像素，且第三子像素30仅包括一种类型子像素。
本示例通过将显示区的边缘像素行组和边缘像素列组的至少之一中的第三子像素设置为其第二角部位于第一角部靠近第二像素行或第二像素列的一侧以调整边缘的第三子像素的亮度中心的位置，有利于改善显示区边缘发紫或发青的现象。此外，将显示区的边缘像素行组和边缘像素列组的至少之一中的第一子像素设置为包括四种不同类型子像素，还有利于降低边缘显示横线或竖线等细节时的色偏问题。
当然，本公开实施例不限于此，本公开另一示例中，位于边缘像素行组和边缘像素列组的至少之一中，仅第一子像素中的第二角部位于第一角部靠近第二像素行或第二像素列的一侧，而位于边缘像素行组和边缘像素列组的至少之一中的第三子像素包括四种类型子像素。例如，边缘像素行组和边缘像素列组的至少之一中，第三子像素包括四种类型子像素，且第一子像素仅包括一种类型子像素。本示例通过将显示区的边缘像素行组和边缘像素列组的至少之一中的第一子像素设置为其第二角部位于第一角部靠近第二像素行或第二像素列的一侧以调整边缘的第一子像素的亮度中心的位置，有利于改善显示区边缘发紫或发青的现象。此外，将显示区的边缘像素行组和边缘像素列组的至少之一中的第三子像素设置为包括四种不同类型子像素，还有利于降低边缘显示横线或竖线等细节时的色偏问题。
例如，图13为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图。图13所示示例与图12所示示例的不同之处在于图13所示显示基板中仅第三子像素30包括四种类型子像素，第一子像素10不包括四种类型子像素，即显示基板中的多个第一子像素10的形状、大小以及排布状态均相同。
本示例通过将显示区的边缘像素行组和边缘像素列组的至少之一中的第三子像素设置为其第二角部位于第一角部靠近第二像素行或第二像素列的一侧以调整边缘的第三子像素的亮度中心的位置，有利于改善显示区边缘发紫或发青的现象。
当然，本公开实施例不限于此，本公开另一示例中，显示基板的包括的多个子像素中，仅第一子像素包括四种类型子像素，第三子像素不包括四种类型子像素，即显示基板中的多个第三子像素的形状、大小以及排布状态均相同。通过将显示区的边缘像素行组和边缘像素列组的至少之一中的第一子像素设置为其第二角部位于第一角部靠近第二像素行或第二像素列的一侧以调整边缘的第一子像素的亮度中心的位置，有利于改善显示区边缘发紫或发青的现象。
例如，图14为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图，图15为图14所示的一个边角子像素的放大图。图14所示示例与图11所示示例的不同之处在于本示例中显示基板的边角子像素102的形状不同于图11所示显示基板的边角子像素102的形状。
例如，如图14和图15所示，边角子像素102中，构成第三角部113的两条直边的延长线的交点Q1到该子像素102的中心P的距离大于构成第四角部114的两条直边或其延长线的交点Q2到该子像素102的中心P的距离，且第四角部114比第三角部113更靠近与该边角子像素102相邻的第二像素行02或第二像素列04。
本公开实施例通过调整边角子像素的第三角部和第四角部的形状关系，可以使得位于显示区四个边角处的蓝色边角子像素或者红色边角子像素的亮度中心向与其相邻的绿色子像素行和绿色子像素列偏移，有利于改善显示区边角处发紫或发青的现象。
例如，如图14和图15所示，边角子像素102中，第一角部111的形状可以与第三角部113的形状大致相同，第四角部114的形状可以与第二角部112的形状大致相同。
图14所示示例示意性的示出显示基板的显示区中除边角子像素外的像素形状以及排布规律与图11所示显示基板的显示区中除边角子像素外的像素形状以及排布规律相同，但不限于此，图14所示的边角子像素的形状以及各角部关系可以应用于上述任一示例提供的显示基板中，以改善显示区边角处的显示效果。
图16为根据本公开一实施例提供的显示基板的局部结构示意图。如图16所示，显示基板包括多个子像素100。如图16所示，多个子像素100包括多个第一子像素10、多个第二子像素20以及多个第三子像素30。多个第一子像素10和多个第三子像素30沿行方向(如图1所示的X方向)和列方向(如图15所示的Y方向)均交替排布以形成多个第一像素行01和多个第一像素列03，多个第二子像素20沿行方向和列方向阵列排布以形成多个第二像素行02和多个第二像素列04，行方向与列方向相交。例如，行方向和列方向可以垂直。行方向和列方向可以互换。
如图16所示，以第一像素行01中相邻的第一子像素10和第三子像素30的中心，以及沿列方向与 该相邻的第一子像素10和第三子像素30分别相邻的第一子像素10和第三子像素30的中心为虚拟四边形101的四个顶点，虚拟四边形101内设置有一个第二子像素20。例如，第二子像素20与相邻第一像素行01中的第一子像素10和第三子像素30交错设置。
如图16所示，各子像素100包括发光区110，显示基板包括至少一个显示区1000。图16示意性的示出显示基板包括的一个显示区，该显示区包括位于四周边缘的像素行和像素列。本公开实施例不限于此，显示基板还可以包括多个显示区，例如显示基板可以为折叠显示基板，根据折叠需求，显示基板可以包括两个显示区、四个显示区或者更多个显示区，各显示区均包括位于四周边缘的像素行和像素列。例如，在显示基板包括的两个显示区相邻时，两个显示区边缘的像素行或像素列也可以彼此相邻，虽然分别位于两个显示区的边缘的两个像素行或者两个像素列并没有位于显示基板的边缘，但是可以根据各显示区对边缘像素的需求进行相应的设计。
如图16所示，位于至少一个显示区1000最边缘的第一像素行01和第一像素列03的第一子像素10和第三子像素30的至少之一中，发光区110的顶角包括相对设置的第一角部111和第二角部112，构成第一角部111的两条直边的延长线的交点到该子像素的中心的距离大于构成第二角部112的两条直边或其延长线的交点到该子像素的中心的距离。本实施例中包括第一角部111和第二角部112的子像素可以与图1至图14所示示例中包括第一角部111和第二角部112的子像素具有相同的特征以及技术效果，在此不再赘述。
如图16所示，位于至少一个显示区1000最边缘且彼此相邻的第一像素行01和第二像素行02构成边缘像素行组012，位于至少一个显示区1000最边缘且彼此相邻的第一像素列03和第二像素列04构成边缘像素列组034，边缘像素行组012和边缘像素列组034的交叉位置设置有边角子像素102，边角子像素102包括第一子像素10和第三子像素30。例如，两个边缘像素行组012和两个边缘像素列组034交叉位置设置有四个边角子像素102，包括两个第一子像素10和两个第三子像素30。
如图16所示，边缘像素行组012中，除边角子像素102外的子像素100中，第二角部112比第一角部111更靠近第二像素行02。
一般显示基板中，各不同颜色子像素的发光区包括的四个顶角的形状均相同，则位于显示区上下边缘的两个像素行分别为红色子像素和蓝色子像素构成的一像素行以及绿色子像素构成的像素行，对于红色子像素和蓝色子像素构成的一像素行作为最边缘的像素行，该侧边缘在显示时容易出现发紫的问题；对于绿色子像素构成的像素行作为最边缘的像素行，该侧边缘在显示时容易出现发青的问题。此外，这种显示基板的发光区的边缘还可能因子像素的角部突出而导致显示时出现锯齿状边缘。
相对于这种显示基板的像素排列，本公开实施例提供的显示基板针对显示区的边缘像素行中子像素的形状进行改进，使得位于边缘像素行组中的蓝色子像素和红色子像素至少之一的第二角部位于第一角部靠近边缘像素行组中的绿色子像素行的一侧，从而使得蓝色子像素和红色子像素至少之一的亮度中心向绿色子像素偏移，以改善了边缘像素行出现发紫或发青的现象。此外，位于最边缘的像素行为蓝色子像素和红色子像素形成的第一像素行时，具有较长弧线长度的圆倒角作为位于边缘侧的第一角部，有利于改善边缘锯齿感。
如图16所示，边缘像素列组034中，除边角子像素102外的子像素100中，第二角部112比第一角 部111更靠近第二像素列04。
一般显示基板中，各不同颜色子像素的发光区包括的四个顶角的形状均相同，则位于显示区左右边缘的两个像素列分别为红色子像素和蓝色子像素构成的一像素列以及绿色子像素构成的像素列，对于红色子像素和蓝色子像素构成的一像素列作为最边缘的像素列，该侧边缘在显示时容易出现发紫的问题；对于绿色子像素构成的像素列作为最边缘的像素列，该侧边缘在显示时容易出现发青的问题。此外，这种显示基板的发光区的边缘还可能因子像素的角部突出而导致显示时出现锯齿状边缘。
相对于这种显示基板的像素排列，本公开实施例提供的显示基板针对显示区的边缘像素列中子像素的形状进行改进，使得位于边缘像素列组中的蓝色子像素和红色子像素至少之一的第二角部位于第一角部靠近边缘像素列组中的绿色子像素列的一侧，从而使得蓝色子像素和红色子像素至少之一的亮度中心向绿色子像素偏移，以改善了边缘像素列出现发紫或发青的现象。此外，位于最边缘的像素列为蓝色子像素和红色子像素形成的第一像素列时，具有较长弧线长度的圆倒角作为位于边缘侧的第一角部，有利于改善边缘锯齿感。
例如，如图16所示，显示基板中的第一子像素10和第三子像素30的至少之一包括图1所示的四种类型子像素，即第一类型子像素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。例如，位于显示区非边缘的子像素中，第一像素行01包括两种类型子像素，第一像素列03包括两种类型子像素。例如，各第一像素行01中包括的两种类型子像素交替排列。例如，各第一像素列03包括两种类型子像素交替排列。
例如，如图16所示，相邻两个第一像素行01包括子像素的类型不同，例如，一个第一像素行01中包括第一类型子像素1001和第二类型子像素1002，与该第一像素行01相邻的第一像素行01中包括第三类型子像素1003和第四类型子像素1004。同理，相邻两个第一像素列03包括子像素的类型不同，例如，一个第一像素列03中包括第一类型子像素1001和第二类型子像素1002，与该第一像素列03相邻的第一像素列03中包括第三类型子像素1003和第四类型子像素1004。
当然，本公开实施例不限于此，各第一像素行包括的两种类型子像素可以为第一类型子像素和第二类型子像素之一，以及第三类型子像素和第四类型子像素之一；各第一像素列包括的两种类型子像素可以为第一类型子像素和第二类型子像素之一，以及第三类型子像素和第四类型子像素之一。
例如，如图16所示，围绕第一子像素10的四个第三子像素30包括四种类型子像素。
图16示意性的示出位于边缘像素行组和边缘像素列组至少之一中的第三子像素包括第一角部和第二角部，而第一子像素不包括第一角部和第二角部，但不限于此，还可以位于边缘像素行组和边缘像素列组至少之一中的第一子像素包括第一角部和第二角部，而第三子像素不包括第一角部和第二角部。
例如，图17为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图，图17所示示例与图16所示示例的不同之处在于，图17所示显示基板中，边缘像素行组012中除边角子像素102外的第一子像素10和第三子像素30均包括第一角部111和第二角部112，边缘像素列组034中除边角子像素102外的第一子像素10和第三子像素30均包括第一角部111和第二角部112。本示例中边缘像素行组和边缘像素列组中子像素的分布规律以及形状等特征以及相应的技术效果可以与图11所示的边缘像素行组和边缘像素列组中子像素的分布规律以及形状等特征以及相应的技术效果相同，在 此不再赘述。当然，本示例不限于此，本示例中边缘像素行组和边缘像素列组中子像素的分布规律以及形状等特征以及相应的技术效果还可以与图12-13所示示例中边缘像素行组和边缘像素列组中子像素的分布规律以及形状等特征以及相应的技术效果相同。
例如，图18为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图，图18所示示例与图17所示示例的不同之处在于，图18所示显示基板中，位于显示区非边缘的各子像素均不包括具有上述特征的第一角部和第二角部，即位于显示区非边缘的各子像素包括的四个角部的形状均大致相同。本示例中边缘像素行组和边缘像素列组中子像素的分布规律以及形状等特征以及相应的技术效果可以与图11所示的边缘像素行组和边缘像素列组中子像素的分布规律以及形状等特征以及相应的技术效果相同，在此不再赘述。当然，本示例不限于此，本示例中边缘像素行组和边缘像素列组中子像素的分布规律以及形状等特征以及相应的技术效果还可以与图12-13所示示例中边缘像素行组和边缘像素列组中子像素的分布规律以及形状等特征以及相应的技术效果相同。
例如，如图18所示，边缘像素行组和边缘像素列组至少之一中的所述第三子像素的面积小于所述至少一个显示区中非边缘区域的所述第三子像素的面积；和/或，所述边缘像素行组和所述边缘像素列组至少之一中的所述第一子像素的面积小于所述至少一个显示区中非边缘区域的所述第一子像素的面积。例如，位于显示区非边缘的各子像素包括的四个角部的形状均大致相同时，位于显示区边缘的第一子像素的形状不同于显示区非边缘的第一子像素的形状，且位于显示区边缘的第一子像素的面积小于显示区非边缘的第一子像素的面积。例如，位于显示区非边缘的各子像素包括的四个角部的形状均大致相同时，位于显示区边缘的第三子像素的形状不同于显示区非边缘的第三子像素的形状，且位于显示区边缘的第三子像素的面积小于显示区非边缘的第三子像素的面积。
例如，图19为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图，图19所示示例与图17所示示例的不同之处在于，本示例中显示基板的边角子像素102的形状不同于图17所示显示基板的边角子像素102的形状。本示例中边角子像素102的形状可以与图14和图15所示的边角子像素102的形状相同。如图19和图15所示，边角子像素102的发光区110的顶角还包括相对设置的第三角部113和第四角部114；边角子像素102中，构成第三角部113的两条直边的延长线的交点Q1到该子像素102的中心P的距离大于构成第四角部114的两条直边或其延长线的交点Q2到该子像素102的中心P的距离，且第四角部114比第三角部113更靠近与该边角子像素102相邻的第二像素行02或第二像素列04。
本公开实施例通过调整边角子像素的第三角部和第四角部的形状关系，可以使得位于显示区四个边角处的蓝色边角子像素或者红色边角子像素的亮度中心向与其相邻的绿色子像素行和绿色子像素列偏移，有利于改善显示区边角处发紫或发青的现象。
例如，如图19所示，边角子像素102中，第一角部111的形状可以与第三角部113的形状大致相同，第四角部114的形状可以与第二角部112的形状大致相同。
图19所示示例示意性的示出显示基板的显示区中除边角子像素外的像素形状以及排布规律与图1-18任一所示显示基板的显示区中除边角子像素外的像素形状以及排布规律相同，但不限于此，图19所示的边角子像素的形状以及各角部关系可以应用于上述任一示例提供的显示基板中，以改善显示区边 角处的显示效果。
例如，图20为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图，图20所示示例与图11所示示例的不同之处在于，本示例中显示基板的显示区中边缘像素行组和边缘像素列组至少之一的第二子像素20包括彼此相对的第一角部111和第二角部112，构成所述第一角部111的两条边的延长线或两条边的切线的交点到该子像素的中心的距离大于构成所述第二角部112的两条边或其延长线或两条边的切线的交点到该子像素的中心的距离。
例如，如图20所示，显示区中边缘像素行组012和边缘像素列组034中的各第二子像素20均包括具有上述关系的第一角部111和第二角部112。
例如，如图20所示，边缘像素行组012中，第二子像素20的第二角部112比第一角部111更靠近第一像素行01，从而使得作为绿色子像素的第二子像素的亮度中心更靠近第一像素行；边缘像素列组034中，第二子像素20的第二角部112比第一角部111更靠近第一像素列03，从使得位于显示区边缘且作为绿色子像素的第二子像素的亮度中心更靠近第一像素列以进一步缓解显示基板的显示区显示时边缘发紫或发青的问题。
例如，如图20所示，本示例中位于显示区非边缘区域的第二子像素20可以不包括具有上述关系的第一角部和第二角部，即位于显示区非边缘区域的第二子像素20包括的四个顶角的形状均相同。
本示例中位于边缘像素行组和边缘像素列组中的第二像素行和第二像素列交叉位置也包括绿色边角子像素，该绿色边角子像素可以与上述第一子像素或第三子像素包括的边角子像素具有相同的特征，在此不再赘述。
本示例中显示区边缘以及非边缘区域的第一子像素和第三子像素的形状以及排列规律可以与图1至图19任一示例中第一子像素和第三子像素的形状以及排列规律相同，在此不再赘述。
例如，图21为根据本公开实施例的另一示例提供的显示基板中的像素排列的局部平面结构示意图，图21所示示例与图20所示示例的不同之处在于，本示例中显示基板中显示区的非边缘区域的第二子像素20包括彼此相对的第一角部111和第二角部112，构成所述第一角部111的两条边的延长线或两条边的切线的交点到该子像素的中心的距离大于构成所述第二角部112的两条边或其延长线或两条边的切线的交点到该子像素的中心的距离。
例如，如图21所示，根据第一角部111指向第二角部112的方向可以将第二子像素20也划分为第一类型子像素、第二类型子像素、第三类型子像素和第四类型子像素，这里的四种类型子像素的定义方式与图1所示四种类型子像素的定义方式相同，但本示例中各类型子像素的第一角部指向第二角部的方向不再平行于行方向和列方向。如图21所示，沿行方向排列的第二子像素20中包括交替排列的两种类型子像素，沿列方向排列的第二子像素20中包括交替排列的另外两种类型子像素，围绕第一子像素的四个第二子像素20包括四种类型子像素；围绕第三子像素的四个第二子像素20包括四种类型子像素。
本公开实施例不限于此，沿方向排列的第二子像素也可以包括四种类型子像素，沿列方向排列的第二子像素也可以包括四种类型子像素。
当然，本示例中显示区边缘以及非边缘区域的第一子像素和第三子像素的形状以及排列规律可以与图1至图19任一示例中第一子像素和第三子像素的形状以及排列规律相同，在此不再赘述。
本公开一实施例提供一种显示基板，如图1和图6所示，显示基板包括多个子像素100，包括多个第一子像素10、多个第二子像素20以及多个第三子像素30；多个第一子像素10和多个第三子像素30沿行方向(如图1所示的X方向)和列方向(如图1所示的Y方向)均交替设置以形成多个第一像素行01和多个第一像素列03，多个第二子像素20沿行方向和列方向阵列排布以形成多个第二像素行02和多个第二像素列04，多个第一像素行01和多个第二像素行02沿列方向交替设置，多个第一像素列02和多个第二像素列04沿行方向交替设置。行方向与列方向相交。例如，行方向和列方向可以垂直。行方向和列方向可以互换。
如图1所示，以第一像素行01中相邻的第一子像素10和第三子像素30的中心，以及沿列方向与该相邻的第一子像素10和第三子像素30分别相邻的第一子像素10和第三子像素30的中心为虚拟四边形101的四个顶点，虚拟四边形101内设置有一个第二子像素20。
例如，上述子像素的中心例如为该子像素的几何中心，或者为该子像素的各个边的中垂线的交点，亦或者为该子像素中到各个边的垂直距离大致相等的点。当然，上述子像素的中心可以允许有一定的误差。例如，子像素的中心可以为以子像素的几何中心为圆心半径为3μm范围内的任何一个点。
如图1所示，各第一像素行01包括沿行方向延伸的第一轴线A1，且多个第一像素行01中的多条第一轴线A1等间距分布，各第一像素列03包括沿列方向延伸的第二轴线A2，且多个第一像素列03中的多条第二轴线A2等间距分布。各子像素包括发光区110，第一子像素10和第三子像素30的至少之一中，发光区110被第一轴线A1和第二轴线A2之一划分为第一部分B1和第二部分B2，且被第一轴线A1和第二轴线A2的另一个划分为第三部分B3和第四部分B4，第一部分B1的面积小于第二部分B2的面积，且第三部分B3的面积和第四部分B4的面积相同。第一子像素10和第三子像素30的至少之一包括第一类型子像素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，第一部分B1和第二部分B2的排列方向不同，且第一类型子像素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，第一部分B1和第二部分B2的排列方向分别为第一方向D1、第二方向D2、第三方向D3和第四方向D4，第一方向D1和第二方向D2相反，且第三方向D3和第四方向D4相反。上述第一部分B1和第二部分B2的排列方向指第一部分的中心指向第二部分的中心的方向。
例如，第一部分B1和第二部分B2的形状不同，第三部分B3和第四部分B4的形状相同。
这里四种类型子像素与图1所示显示基板中的四种类型子像素相同，且这里的第一部分B1和第二部分B2的排列方向即为图1所示显示基板中第一角部的顶点指向第二角部的顶点的方向。
需要说明的是，上述图1至图13任一示例提供的显示基板中的描述均适用于这里的显示基板，对于其结构以及技术效果的描述不再赘述。
