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“电连接”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、B和C中的至少一个”与“A、B或C中的至少一个”具有相同含义，均包括以下A、B和C的组合：仅A，仅B，仅C，A和B的组合，A和C的组合，B和C的组合，及A、B和C的组合。

在本公开的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。
应当理解的是，当层或元件被称为在另一层或基板上时，可以是该层或元件直接在另一层或基板上，或者也可以是该层或元件与另一层或基板之间存在中间层。
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。
图1为本公开的一些实施例提供的显示装置的俯视图。该显示装置100可以是显示不论运动(例如，视频)还是固定(例如，静止图像)的且不论文字还是的图像的任何装置。更明确地说，预期实施例可实施在多种电子装置 中或与多种电子装置关联，多种电子装置例如(但不限于)移动电话、无线装置、个人数据助理(Personal Digital Assistant，简称PDA)、手持式或便携式计算机、全球定位系统(Global Positioning System，简称GPS)接收器/导航器、相机、MP4视频播放器、摄像机、游戏控制台、手表、时钟、计算器、电视监视器、平板显示器、计算机监视器、汽车显示器(例如，里程表显示器等)、导航仪、座舱控制器和/或显示器、相机视图的显示器(例如，车辆中后视相机的显示器)、电子相片、电子广告牌或指示牌、投影仪、建筑结构、包装和美学结构(例如，对于一件珠宝的图像的显示器)等。图1中以该显示装置100为手机为例进行示意。
如图1所示，上述显示装置100包括显示面板200，该显示面板200可以为有机电致发光(Organic Light-Emitting Diode，简称OLED)显示面板。
图2为本公开的一些实施例所提供的显示面板200的俯视图，如图2和图4所示，该显示面板200包括衬底1，以及设置于衬底1上的多个子像素P。
多个子像素P划分为多个第一像素列T1和多个第二像素列T2，第一像素列T1和第二像素列T2均沿第一方向X延伸，多个第一像素列T1和多个第二像素列T2沿第二方向Y交替设置。
其中，第一方向X和第二方向Y相交叉。例如，第一方向X与第二方向Y可以相互垂直。在本公开的实施例中，通过将附图进行一定角度(例如30度、45度或90度等)的旋转所得到的技术方案亦在本公开的保护范围之内。
参见图2，第一像素列T1包括沿第一方向X交替设置的多个第一像素组K1和多个第三像素组K3，每个第一像素组K1包括沿第一方向X依次设置的两个第一子像素P1，每个第三像素组K3包括沿第一方向X依次设置的两个第三子像素P3。
继续参见图2，第二像素列T2包括沿第一方向X依次设置的多个第二像素组K2，每个第二像素组K2包括沿第一方向X依次设置的两个第二子像素P2。
示例性地，第一子像素P1、第二子像素P2以及第三子像素P3分别发射不同颜色的光。其中，一个子像素P(第一子像素P1、第二子像素P2或第三子像素P3)发射的光的颜色可以为蓝色、绿色、红色和白色中的一种。
并且，如图3所示，在每个第二像素组K2中，两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，即两个第二子像素P2的发光区Z的几何中心H的连线，与第一方向X之间具有夹角。
例如图3所示，每个第二像素组K2的两个第二子像素P2，其中一者的发光区Z的几何中心H处于沿第一方向X延伸的第一直线L1上，另一者的发光区Z的几何中心H处于沿第一方向X延伸的第二直线L2上。其中，第一直线L1和第二直线L2沿第二方向Y并列排布。
需要说明的是，上述“发光区Z”是指，每个子像素P的有效发光区域。“发光区Z的几何中心H”是指，发光区Z在衬底1上的正投影所对应的图形的几何中心，例如，当发光区Z对应的平面图形为三角形时，发光区Z的几何中心H就是该三角形的几何中心。发光区Z的几何中心H与该发光区Z对应的子像素P的发光亮度中心的位置大致一致。
本公开的一些实施例所提供的显示面板200，在每个第二像素组K2中，两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，即两个第二子像素P2的发光区Z的几何中心H的连线，与第一方向X之间具有夹角，这样，在子像素P发光的过程中，同一个第二像素组K2中的两个第二子像素P2的发光区域的亮度中心，在第二方向Y上相互错开，可提高第二像素组K2中的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
示例性地，如图4所示，显示面板200包括层叠设置于衬底1上的驱动电路2、发光器件3以及封装层4。
衬底1可为单层结构，也可为多层结构。例如，该衬底1可包括依次层叠设置的聚酰亚胺层101和缓冲层102。又例如，在另一些实施例中，衬底1可包括多个依次层叠设置的聚酰亚胺层101和缓冲层102。缓冲层102的材料可包括氮化硅和/或氧化硅，以达到阻水氧和阻隔碱性离子的效果。
驱动电路2包括依次层叠设置在衬底1上的有源层201、第一栅绝缘层202、第一栅导电层203、第二栅绝缘层204、第二栅导电层205、层间介质层206、第二源漏导电层207、钝化层208、第二平坦化层209、第一源漏导电层210以及第一平坦化层211。
可选地，源漏导电层可以只有一层(例如只有第一源漏导电层210或只有第二源漏导电层207)，相应地，平坦化层只有一层(例如只有第一平坦化层211或只有第二平坦化层209)。
驱动电路2设置有多个薄膜晶体管TFT和多个电容结构Cst，图4中仅示例性示出了其中两个薄膜晶体管TFT和对应的两个电容结构Cst。
示例性地，薄膜晶体管包括栅极T1、源极T2、漏极T3以及有源层图 案T4。其中，栅极T1位于第一栅导电层203，源极T2和漏极T3位于第二源漏导电层207，有源层图案T4位于有源层201。
示例性地，电容结构Cst包括第一极板Cst1和第二极板Cst2，其中，第一极板Cst1位于第一栅导电层203，第二极板Cst2位于第二栅导电层205。
在示例性实施例中，发光器件层3包括依次层叠设置在驱动电路2上的第一电极层301、像素界定层302、发光功能层303以及第二电极层304。发光器件层3设置有多个发光器件L。发光器件L包括位于第一电极层301的第一电极L1、位于第二电极层304的第二电极L2以及位于发光功能层303的发光层L3。
示例性地，发光层L3可包括发光图案K。在另一些实施例中，发光层L3除包括发光图案K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。
示例性地，像素界定层302开设有多个开口Q，发光图案K至少部分位于开口Q内，子像素P产生的光通过开口Q发射至外界，因此，前述“发光区”，也即为，每个子像素P与像素界定层302中的开口Q相对的区域。因此，发光区Z的几何中心H可以等同于像素界定层302中的开口Q的平面形状的几何中心，开口Q的平面形状的面积即为子像素P发射的光的发光区域的面积。
示例性地，像素界定层302和第二电极层304之间还可设置有支撑层305，该支撑层305可起到支撑保护膜层的作用，以避免保护膜层与第一电极层301或其他走线接触而导致第一电极层301或其他走线断裂。
在示例性实施例中，封装层4包括依次层叠设置在发光器件层3上的第一封装层401、第二封装层402和第三封装层403。
在一些实施例中，第二子像素P2能够发射绿色光。
在显示面板200的发光过程中，相对于红色光和蓝色光，绿色光的发光强度占比较大，其占比可以高达50％以上，因此，当绿色光发光过于集中时，会影响显示面板200的显示效果。
在前述实施例中，在同一个第二像素组K2中的两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，且第二子像素P2能够发射绿色光，也即，该第二像素组K2中的绿色光的发光区域的亮 度中心处于沿第一方向X延伸的两条直线上，使得第二像素组K2中的绿色光的发光区域的亮度中心在第二方向Y上相互错开，使第二像素组K2中绿色光发光均匀。从而提高显示面板200中占比较大的绿色光的发光均匀性，有效提升显示装置100的显示效果。
第一子像素P1能够发射红色光或蓝色光中的一种，第三子像素P3能够发射红色光或蓝色光中的另一种。例如，第一子像素P1能够发射红色光，第三子像素P3发射蓝色光。或者，第一子像素P1能够发射蓝色光，第三子像素P3发射红色光。
需要说明的是，第一子像素P1、第二子像素P2和第三子像素P3能够发射的颜色光并不局限于上述的红色、绿色、蓝色，例如还可以发白色光，本公开对此不作限定。
如图5所示，在一些实施例中，两个第一子像素P1的发光区的几何中心H分别处于沿第一方向X延伸的两条直线上。其中，两个第一子像素P1是指位于同一第一像素组K1的两个第一子像素P1。例如图5所示，处于同一第一像素组K1的两个第一子像素P1中，其中一者的发光区的几何中心H处于沿第一方向X延伸的第三直线L3上，另一者的发光区的几何中心H处于沿第一方向X延伸的第四直线L4上。其中，第三直线L3和第四直线L4沿第二方向Y并列排布。
在前述实施例中，在每个第一像素组K1中，两个第一子像素P1的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，即两个第一子像素P1的发光区Z的几何中心H的连线，与第一方向X之间具有夹角，这样，在子像素P发光的过程中，同一个第一像素组K1中的两个第一子像素P1的发光区域的亮度中心，在第二方向Y上相互错开，可提高第一像素组K1中的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
如图5所示，在一些实施例中，两个第三子像素P3的发光区的几何中心H分别处于沿第一方向X延伸的两条直线上。其中，两个第三子像素P3是指位于同一第三像素组K3的两个第三子像素P3。例如图5所示，处于同一第三像素组K3的两个第三子像素P3中，其中一者的发光区的几何中心H处于沿第一方向X延伸的第五直线L5上，另一者的发光区的几何中心H处于沿第一方向X延伸的第六直线L6上。其中，第五直线L5和第六直线L6沿第二方向Y并列排布。
在前述实施例中，在每个第三像素组K3中，两个第三子像素P3的发光 区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，即两个第三子像素P3的发光区Z的几何中心H的连线，与第一方向X之间具有夹角，这样，在子像素P发光的过程中，同一个第三像素组K3中的两个第三子像素P3的发光区域的亮度中心，在第二方向Y上相互错开，可提高第三像素组K3中的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
示例性地，同一像素组中的能够发射红色光的两个子像素P的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上。例如，第一子像素P1发射红色光，位于同一第一像素组K1中的两个第一子像素P1的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上。
在前述实施例中，同一像素组中的能够发射红色光的两个子像素P的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，也即，该像素组中的红色光的发光区域的亮度中心处于沿第一方向X延伸的两条直线上，使得像素组中的红色光的发光区域的亮度中心在第二方向Y上相互错开，使第二像素组K2中红色光发光均匀，从而提高显示面板200中红色光的发光均匀性，有效提升显示装置100的显示效果。
示例性地，同一像素组中的能够发射蓝色光的两个子像素P的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上。例如，第三子像素P3发射蓝色光，位于同一第三像素组K3中的两个第三子像素P3的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上。
在前述实施例中，同一像素组中的能够发射蓝色光的两个子像素P的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，也即，该像素组中的蓝色光的发光区域的亮度中心处于沿第一方向X延伸的两条直线上，使得像素组中的蓝色光的发光区域的亮度中心在第二方向Y上相互错开，使第二像素组K2中蓝色光发光均匀，从而提高显示面板200中蓝色光的发光均匀性，有效提升显示装置100的显示效果。
示例性地，同一像素组中的两个能够发射蓝色光的子像素P的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，同时，同一像素组中的两个能够发射红色光的子像素P的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，同时，同一像素组中的两个能够发射绿色光的子像素P的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，从而增强显示面板200的蓝色光、红色光以及绿色光的发光均匀性，进一步提升显示装置100的显示效果。
如图5所示，在一些实施例中，第三子像素P3的发光区Z的面积大于第一子像素P1发光区Z的面积，第三子像素P3的发光区Z的面积大于第二子像素P2发光区Z的面积。例如图5所示，在第一子像素P1能够发射红色光，第二子像素P2能够发射绿色光，第三子像素P3能够发射蓝色光的情况下，第三子像素P3的发光区Z的面积大于第一子像素P1的发光区Z的面积，且大于第二子像素P2的发光区Z的面积，也即能够发射蓝色光的子像素P的发光区Z的面积，大于能够发射红色光的子像素P的发光区Z的面积，且大于能够发射绿色光的子像素P的发光区Z的面积。
在第一子像素P1、第二子像素P2和第三子像素P3的发光亮度相同的情况下，第三子像素P3的工作电压较高，发光器件L工作在高压环境下，会导致发光器件L中的发光层L3的材料寿命较短。因此，通过设置第三子像素P3的发光区Z的面积较大，可以延长其发光器件L中的发光层L3材料的使用寿命。如图6所示，在一些实施例中，同一个第二像素列T2中，多个第二子像素P2的发光区Z位于第一参考线N1和第二参考线N2之间，且第二子像素P2的发光区Z的至少一条边或至少一个点位于第一参考线N1上，至少另一条边或至少另一个点位于第二参考线N2上。其中，第一参考线N1和第二参考线N2沿第一方向X延伸，且沿第二方向Y并列设置。
可以理解的是，同一个第二像素列T2中的多个子像素P的发光区Z沿第二方向Y上的最长宽度均大致相等，均与第一参考线N1和第二参考线N2沿第二方向Y上的间距大致相等。
示例性地，同一个第一像素列T1中，多个第一子像素P1的发光区Z和多个第三子像素P3的发光区Z均位于沿第一方向X延伸、且沿第二方向Y并列设置的两条参考线之间，也即，同一个第一像素列T1中的多个子像素P的发光区Z沿第二方向Y上的最长宽度均大致相等，均与前述两条参考线沿第二方向Y上的间距大致相等。
如图7所示，在一些实施例中，位于同一第二像素组K2的两个第二子像素P2的发光区Z的形状大致相同，且两个发光区Z呈中心对称设置。
需要说明的是，参考图7，位于同一第二像素组K2的两个第二子像素P2的发光区Z，以对称点P’为对称中心相互对称，即，将其中一个第二子像素P2的发光区Z，绕对称点P’旋转180度后，与另一个第二子像素P2的发光区重合。
通过上述设置方式，同一第二像素组K2的两个第二子像素P2的发光区Z的形状大致相同，使同一第二像素组K2中的两个第二子像素P2的发光区Z 的面积大致相等，且两个发光区Z呈中心对称设置，可以使同一第二像素组K2中的两个第二子像素P2的发光区Z的排布更紧凑，从而提高显示装置100的PPI。
在示例性实施例中，位于同一第一二像素组的两个第一子像素P1的发光区Z的形状大致相同，且两个发光区Z呈中心对称设置。从而使同一第一像素组K1中的两个第一子像素P1的发光区Z的排布更紧凑，提高显示装置100的PPI。
在示例性实施例中，位于同一第三像素组K3的两个第三子像素P3的发光区Z的形状大致相同，且两个发光区Z呈中心对称设置。从而使同一第三像素组K3中的两个第三子像素P3的发光区Z的排布更紧凑，提高显示装置100的PPI。
在一些实施例中，位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的一条边与另一者的发光区Z的一条边相邻设置且相互平行。
示例性地，第二子像素P2的发光区Z的形状为梯形、三角形或包括至少5条边的多边形。例如，第二子像素P2的发光区Z的形状为等腰梯形、直角梯形、扇形、等腰三角形、五边形或六边形等。
例如图9所示，当发光区Z呈三角形时，其中一者的腰边与另一者的腰边相邻设置且相互平行。相邻的两个第二子像素P2相互靠近的边相互平行设置，从而控制每个第二像素组K2中相邻的两个第二子像素P2之间的间距大致相等，从而使相邻的两个第二子像素P2之间的空间实现最大化利用，避免由于第二子像素P2发光区Z形状变化导致显示装置100的开口率降低。
在一些实施例中，位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的部分边界与另一者的发光区Z的部分边界相邻设置，且相邻设置的两部分边界上各自至少有一点的切线相互平行。
如图11所示，示例性地，第二子像素P2的发光区Z的形状为弓形，两个第二子像素P2各自发光区Z的弧边的至少部分相邻设置，且各自发光区Z的弧边的至少一条切线相互平行，同样可以控制每个第二像素组K2中相邻的两个第二子像素P2之间的间距大致相等，从而使相邻的两个第二子像素P2之间的空间实现最大化利用，避免由于第二子像素P2发光区Z形状变化导致显示装置100的开口率降低。
根据前文所述，第二子像素P2的发光区Z的形状为梯形、弓形、三角形或包括至少5条边的多边形。例如，第二子像素P2的发光区Z的形状为等腰 梯形、直角梯形、扇形、等腰三角形、五边形或六边形等。但是，第二子像素P2的发光区Z的形状不可以是正多边形，例如，不可以是正三角形、正五边形或者正六边形等，因为，正多边形的几何中心处于图形的正中间，其与正多边形的每一条边的距离相等，当两个第二子像素P2的发光区Z的形状大致相同且呈中心对称时，无法使两者的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上，从而造成相邻两个第二子像素P2发光过于集中的问题。
需要说明的是，第二子像素P2的发光区Z的形状并不限制于前述形状，能够实现同一像素组中的两个子像素的发光区Z的几何中心H分别处于沿第一方向X延伸的两条直线上的效果的形状均在本公开实施例的保护范围内。
如图3和图8所示，在一些实施例中，第二子像素P2的发光区Z的形状为梯形，梯形包括底边(如图3示出的底边S1)和顶边(如图3示出的顶边S2)，发光区Z的底边S1和顶边S2均沿第一方向X延伸；位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的发光区Z的顶边S2处于沿第一方向X延伸的同一条直线上。即，位于同一第二像素组K2的两个第二子像素P2中，两者的发光区Z的底边S1分别处于沿第一方向X延伸的两条不同的直线上，同理，两者的发光区Z的顶边S2也分别处于沿第一方向X延伸的两条不同的直线上。
可以理解的是，梯形的几何中心相对于其顶边S2，更靠近梯形的底边S1，通过上述设置方式，位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的发光区Z的顶边S2处于沿第一方向X延伸的同一条直线上，可以在保证第二像素列T2的宽度(沿第二方向Y的尺寸)不发生变化的情况下，使两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条不同的直线上，即两个第二子像素P2的发光区域的亮度中心在第二方向Y上相互错开，从而提高第二像素组K2中的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
如图3所示，示例性地，第二子像素P2的发光区Z的形状为等腰梯形；位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的一条腰(例如腰S31)与另一者的发光区Z的一条腰(例如腰S32)相邻设置且相互平行。从而在提高显示面板200的发光亮度的均匀性的同时，控制每个第二像素组K2中相邻的两个第二子像素P2之间的间距大致相等，避免由于第二子像素P2发光区Z形状变化导致显示装置100的开口率降低。
如图8所示，示例性地，第二子像素P2的发光区Z的形状为直角梯形， 发光区Z包括底边S1、顶边S2、腰S3以及垂直于底边和顶边的直角边S4；位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的腰(例如腰S31)与另一者的腰(例如腰S32)发光区Z的相邻设置且相互平行。从而在提高显示面板200的发光亮度的均匀性的同时，控制每个第二像素组K2中相邻的两个第二子像素P2之间的间距大致相等，避免由于第二子像素P2发光区Z形状变化导致显示装置100的开口率降低。
如图9和图10所示，在一些实施例中，第二子像素P2的发光区Z的形状为三角形，三角形包括底边(如图9示出的底边S1)和与底边S1相对的顶点(如图9示出的顶点O)，发光区Z的一条边沿第一方向X延伸。其中，沿第一方向X延伸的一条边为底边S1。位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1所对应的顶点O与另一者的发光区Z的底边S1处于沿第一方向X延伸的同一条直线上。即，位于同一第二像素组K2的两个第二子像素P2中，两者的发光区Z的底边S1分别处于沿第一方向X延伸的两条不同的直线上，同理，两者的发光区Z的顶点O也分别处于沿第一方向X延伸的两条不同的直线上。
可以理解的是，三角形(除等边三角形外)的几何中心相对于顶点O，更靠近与该顶点O相对的边(即底边S1)，通过上述设置方式，位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的发光区Z的顶点O处于沿第一方向X延伸的同一条直线上，可以在保证第二像素列T2的宽度(沿第二方向Y的尺寸)不发生变化的情况下，使两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条不同的直线上，即两个第二子像素P2的发光区域的亮度中心在第二方向Y上相互错开，从而提高第二像素组K2中的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
如图9所示，示例性地，第二子像素P2的发光区Z的形状为等腰三角形，发光区Z包括底边S1和两条腰边S3，两条腰边S3的交点为顶点O。发光区Z的底边S1沿第一方向X延伸；位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的一条腰S31与另一者的发光区Z的一条腰S32相邻设置且相互平行。从而在提高显示面板200的发光亮度的均匀性的同时，控制每个第二像素组K2中相邻的两个第二子像素P2之间的间距大致相等，避免由于第二子像素P2发光区Z形状变化导致显示装置100的开口率降低。
如图10所示，示例性地，第二子像素P2的发光区Z的形状为直角三角形，发光区Z包括底边S1、长直角边S5和短直角边S6，长直角边S5和短直 角边S6的交点为顶点O。发光区Z的底边S1沿第一方向X延伸；位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1对应的顶点O与另一者的发光区Z的底边S1处于沿第一方向X延伸的同一条直线上，其中一者的发光区Z的长直角边S51与另一者的发光区Z的长直角边S52相邻设置且相互平行。从而在提高显示面板200的发光亮度的均匀性的同时，控制每个第二像素组K2中相邻的两个第二子像素P2之间的间距大致相等，避免由于第二子像素P2发光区Z形状变化导致显示装置100的开口率降低。
如图11所示，在一些实施例中，第二子像素P2的发光区Z的形状为弓形，发光区Z包括底边S1和与底边S1相连的弧边S7，底边S1沿第一方向X延伸；位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的发光区Z的弧边S7上距离底边S1最远的点O’处于沿第一方向X延伸的同一条直线上。即，位于同一第二像素组K2的两个第二子像素P2中，两者的发光区Z的底边S1分别处于沿第一方向X延伸的两条不同的直线上，同理，两者的发光区Z的弧边S7上距离底边最远的点O’也分别处于沿第一方向X延伸的两条不同的直线上。
可以理解的是，弓形的几何中心更靠近弓形的底边S1，通过上述设置方式，位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的发光区Z的弧边S7上距离底边最远的点O’处于沿第一方向X延伸的同一条直线上，可以在保证第二像素列T2的宽度(沿第二方向Y的尺寸)不发生变化的情况下，使两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条不同的直线上，即两个第二子像素P2的发光区域的亮度中心在第二方向Y上相互错开，从而提高第二像素组K2中的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
示例性地，第二子像素P2的发光区Z的形状为扇形(例如为半圆形)，扇形的几何中心更靠近扇形的底边，通过使位于同一第二像素组K2的两个子像素的发光区Z的底边分别处于沿第一方向X延伸的两条不同的直线上，同理，使两者的发光区Z的弧边上距离底边最远的点也分别处于沿第一方向X延伸的两条不同的直线上，可以在保证第二像素列T2的宽度(沿第二方向Y的尺寸)不发生变化的情况下，使两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条不同的直线上，即两个第二子像素P2的发光区域的亮度中心在第二方向Y上相互错开，从而提高第二像素组K2中 的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
如图12和图13所示，在一些实施例中，第二子像素P2的发光区Z的形状为五边形，发光区Z包括底边S1、分别与底边S1的两端连接且垂直于底边S1的两条直角边S8以及分别与两条直角边S8连接的两条腰S3；底边S1沿第一方向X延伸，两条腰S3相互连接，连接点为顶点O；位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的顶点O处于沿第一方向X延伸的同一条直线上，即，位于同一第二像素组K2的两个第二子像素P2中，两者的发光区Z的底边S1分别处于沿第一方向X延伸的两条不同的直线上，同理，两者的发光区Z的顶点O也分别处于沿第一方向X延伸的两条不同的直线上。
可以理解的是，五边形(除正五边形外)的几何中心相对于其顶点O，更靠近与该顶点O相对的底边S1，通过上述设置方式，位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的发光区Z的顶点O处于沿第一方向X延伸的同一条直线上，可以在保证第二像素列T2的宽度(沿第二方向Y的尺寸)不发生变化的情况下，使两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条不同的直线上，即两个第二子像素P2的发光区域的亮度中心在第二方向Y上相互错开，从而提高第二像素组K2中的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
其中一者的发光区Z的一条直角边S81与另一者的发光区Z的一条直角边S82相邻设置且相互平行。从而在提高显示面板200的发光亮度的均匀性的同时，控制每个第二像素组K2中相邻的两个第二子像素P2之间的间距大致相等，避免由于第二子像素P2发光区Z形状变化导致显示装置100的开口率降低。
如图12所示，示例性地，第二子像素P2的发光区Z的形状为五边形，五边形的两条腰S3长度相同，且两条腰S3以经过顶点O并沿第二方向Y延伸的直线(例如图12所示的虚线段d)对称。从而在提高显示面板200的发光亮度的均匀性的同时，使第二子像素P2的发光区Z的形状规则。
如图13所示，示例性地，第二子像素P2的发光区Z的形状为五边形，五边形的两条腰S3中的其中一条腰S3与一条直角边S8垂直。从而在提高显示面板200的发光亮度的均匀性的同时，最大程度增大发光区Z的面积，提高显示面板200的开口率。
如图14所示，在一些实施例中，第二子像素P2的发光区Z的形状为六边形，发光区Z包括底边S1、分别与底边S1的两端连接且垂直于底边S1的两条直角边S8、分别与两条直角边S8连接的两条腰S3以及与两条腰S3连接的顶边S2；底边S1和顶边S2沿第一方向X延伸；位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的发光区Z的顶边S2处于沿第一方向X延伸的同一条直线上。即，位于同一第二像素组K2的两个第二子像素P2中，两者的发光区Z的底边S1分别处于沿第一方向X延伸的两条不同的直线上，同理，两者的发光区Z的顶边S2也分别处于沿第一方向X延伸的两条不同的直线上。
可以理解的是，六边形(除正六边形外)的几何中心相对于其顶边S2，更靠近梯形的底边S1，通过上述设置方式，位于同一第二像素组K2的两个第二子像素P2中，其中一者的发光区Z的底边S1与另一者的发光区Z的顶边S2处于沿第一方向X延伸的同一条直线上，可以在保证第二像素列T2的宽度(沿第二方向Y的尺寸)不发生变化的情况下，使两个第二子像素P2的发光区Z的几何中心H分别处于沿第一方向X延伸的两条不同的直线上，即两个第二子像素P2的发光区域的亮度中心在第二方向Y上相互错开，从而提高第二像素组K2中的发光区域的发光亮度的均匀性，从而可提高显示面板200的发光亮度的均匀性。
其中一者的发光区Z的一条直角边S81与另一者的发光区Z的一条直角边S82相邻设置且相互平行。从而在提高显示面板200的发光亮度的均匀性的同时，控制每个第二像素组K2中相邻的两个第二子像素P2之间的间距大致相等，避免由于第二子像素P2发光区Z形状变化导致显示装置100的开口率降低。
示例性地，第二子像素P2的发光区Z的形状为六边形，六边形的两条腰可以为弧线，从而在提高显示面板200的发光亮度的均匀性的同时，最大程度增大发光区Z的面积，提高显示面板200的开口率。
此外，在一些实施例中，第一子像素P1和第三子像素P3中的至少一者的发光区Z的形状为梯形、弓形、三角形或至少五条边的多边形。例如，第一子像素P1和第三子像素P3的发光区Z的形状均为直角梯形，或者均为等腰三角形、均为具有两个直角的五边形或均为具有两个直角的六边形等。通过对第一子像素P1和第三子像素P3的发光区的形状设计，使第一子像素P1和第三子像素P3发射的颜色光分布均匀，提高显示面板200的整屏发光均匀性，增强显示装置100的显示效果。
如图15所示，在一些实施例中，多个子像素P划分为多个像素行R，像素行R沿第二方向Y延伸，且多个像素行R沿第一方向X并列设置；像素行R包括沿第二方向Y依次设置的多个像素单元R’，像素单元R’包括第一像素组K1、第二像素组K2和第三像素组K3；相邻两个像素行R的像素单元R’在第二方向Y相互错开设置。
通过将像素单元R’相互错开，使得第二像素组K2和与其相邻的第一像素组K1、第三像素组K3之间均具有正对面积，从而使得发射不同颜色光的子像素P之间布置紧凑，提高显示装置100的开口率。
如图16所示，在一些实施例中，显示面板200包括多个像素M，至少一个像素M包括第一子像素P1、第二子像素P2和第三子像素P3。其中，位于一个第一像素列T1中彼此相邻的一个第一子像素P1和一个第三子像素P3、以及位于与该第一像素列T1相邻的第二子像素P2列中的一个第二子像素P2构成一个像素M。多个像素M分别沿第一方向X和第二方向Y排列设置，多个像素M排布紧凑，提高了显示装置100的开口率和PPI。
如图4所示，在一些实施例中，显示面板200还包括像素界定层302和发光层L3。像素界定层302包括多个开口Q，发光层L3包括多个发光图案K，一个第二像素组K2的两个第二子像素P2共用一个发光图案K。一个发光图案K对应两个开口Q，且发光图案K至少部分位于对应的两个开口Q内。
两个开口Q的几何中心分别处于沿第一方向X延伸的两条直线上。发光图案K通过开口Q将颜色光发射，因此开口Q的面积即为发光区Z的面积，两个开口Q的几何中心分别处于沿第一方向X延伸的两条直线上，使得位于同一个第二像素组K2中的两个第二子像素P2在发射颜色光的过程中，颜色光的发光亮度中心在第二方向Y上相互错开，从而避免第二像素组K2中的两个第二子像素P2发光集中，增强显示面板200的整屏发光均匀性。
在示例性实施例中，前述每个子像素(包括第一子像素P1、第二子像素P2和第三子像素P3)均包括发光图案K，同一个像素组中的两个子像素的发光图案K的材料相同且一体设置，例如，一个第二像素组K2中的两个第二子像素P2所对应的发光图案K为一体设置，且能够发射同一种颜色光。
在通过构图工艺形成同一种颜色的发光层L3的过程中，分别采用掩膜板的不同开口形成相邻的子像素P，会由于工艺原因使相邻的子像素P的发光图案K之间存在间隔，降低了显示面板200的开口率，通过上述将同一像素组中的两个子像素P对应的发光图案K一体设置的实施例，减少了发射相同颜色光的子像素P的发光图案K之间的间隔，有效减少非发光区Z域的面积， 提高显示面板200的PPI和开口率。
需要说明的是，如图16所示，每个子像素P的发光图案K包括位于对应像素界定层302开口Q内的有效部分，以及位于像素界定层302的主体(除开口Q外)上的边缘部分。在形成发光层L3的构图工艺中，与每个子像素P对应的掩膜板的开口在衬底1上的正投影与该子像素P的发光图案K(其有效部分与边缘部分构成的整体)在衬底1上的正投影重叠，例如图16所示，第二子像素P2的发光图案K在衬底1上的正投影为区域K’，同理，在构图工艺中，制备第二子像素P2的发光图案K的掩膜板的开口在衬底1上的正投影也为区域K’。
