传统的OLED显示面板中的像素的发光材料层一般是通过蒸镀工艺形成的。在形成像素的发光材料层的过程中，相邻的两个像素的发光材料层之间需要预留一定的间隙，以防止不同像素的发光材料相互干扰。

如图1所示，所述预定形状为椭圆形；如图2所示，所述预定形状为圆形；如图3所示，所述预定形状为椭圆形；如图4所示，所述预定形状为圆形。
所述第一像素101的形状与所述预定形状为相同或相似的形状。
所述第一像素101的形状的中心与所述预定形状的中心相同。
在所述第一像素101的形状为椭圆形时，所述椭圆形的长轴指向所述第二像素102、所述第三像素103中的一者，所述椭圆形的短轴指向所述第二像素102、所述第三像素103中的另一者。

在所述第二像素102的形状为圆形或椭圆形，所述第三像素103的形状为由内凹弧线或内凹弧线与外凸弧线的组合构成的形状时，构成所述第三像素103的形状的至少四内凹弧线中的一者的曲率大于（相邻的）另一者的曲率，即，四内凹弧线中的相邻两者的曲率不相等。
如图2所示，所述第二像素102的形状为圆形，所述第三像素103朝向所述第二像素102的边缘部所对应的内凹弧线的曲率半径大于所述第三像素103朝向所述第一像素101的边缘部所对应的内凹弧线的曲率半径。
在所述第二像素102的形状和所述第三像素103的形状均为由内凹弧线或内凹弧线与外凸弧线的组合构成的形状时，构成所述第三像素103的形状的至少四内凹弧线中的一者的曲率大于或等于构成所述第二像素102的形状的至少四内凹弧线中的一者的曲率。

在上述技术方案中，由于所述第一像素的形状为圆形或椭圆形，并且所述第二像素、所述第三像素中的边缘部的形状与内凹弧线对应，所述第一像素的边缘部的形状的曲率半径与预定间隙的宽度之和等于所述第二像素、所述第三像素中的一者的边缘部所对应的内凹弧线的曲率半径，因此，本发明能有效减小像素之间未被利用的空间，从而有效地提升像素的开口率。
在上述技术方案中，由于所述第一像素的形状为圆形或椭圆形，所述第二像素的形状为圆形、椭圆形、由内凹弧线与外凸弧线构成的形状中的一者，所述第三像素的形状为由内凹弧线与外凸弧线构成的形状，因此有利于像素的制作，并有效地提升像素的开口率。
一所述像素重复单元内所有的所述第一像素101的总面积（例如，一个所述第一像素101的面积、两个所述第一像素101的面积之和）、所有的所述第二像素102的总面积（例如，一个所述第二像素102的面积、两个所述第二像素102的面积之和）、所有的所述第三像素103的总面积（例如，一个所述第三像素103的面积、两个所述第三像素103的面积之和）分别与所述第一像素101的发光材料的发光效率、所述第二像素102的发光材料的发光效率、所述第三像素103的发光材料的发光效率呈反比。
所述红色像素的开口率与所述绿色像素的开口率的比值y1处于以下范围内：0.78e^(-1.98r)≤y1≤2.297e^(-1.85r)，并且0.1≤y1≤3，其中，r为所述红色像素的发光效率与所述绿色像素的发光效率的比值；所述蓝色像素的开口率与所述绿色像素的开口率的比值y2处于以下范围内：1.32e^(-10.7b)≤y2≤5.95e^(-14.1b)，并且0.3≤y2≤4，其中，b为所述蓝色像素的发光效率与所述绿色像素的发光效率的比值。
所述红色像素的开口率与所述绿色像素的开口率的比值y1可例如为0.1、0.2、0.3、0.4、0.5、0.6、0.7、0.8、0.9、1、1.1、1.2、1.3、1.4、1.5、1.6、1.7、1.8、1.9、2、2.1、2.2、2.3、2.4、2.5、2.6、2.7、2.8、2.9、3中的一者，优选地，所述红色像素的开口率与所述绿色像素的开口率的比值y1处于0.2至2.2的范围内，即，0.2≤y1≤2.2；所述蓝色像素的开口率与所述绿色像素的开口率的比值y2可例如为0.3、0.4、0.5、0.6、0.7、0.8、0.9、1、1.1、1.2、1.3、1.4、1.5、1.6、1.7、1.8、1.9、2、2.1、2.2、2.3、2.4、2.5、2.6、2.7、2.8、2.9、3、3.1、3.2、3.3、3.4、3.5、3.6、3.7、3.8、3.9、4中的一者，优选地，所述蓝色像素的开口率与所述绿色像素的开口率的比值y2处于0.5至3.6的范围内，即，0.5≤y2≤3.6。如图9和图10所示。在这一范围内各种不同材料效率在驱动时作用在红色像素、绿色像素、蓝色像素上的电流密度相等或大致相等，而在长时间使用下，红色像素、绿色像素、蓝色像素的材料衰减程度相近，从而显示面板整体的色偏程度都能落在较优的范围内。
传统的显示面板的红色像素、绿色像素、蓝色像素的开口率和发光效率不存在以上关系（即，不存在：0.78e^(-1.98r)≤y1≤2.297e^(-1.85r)，并且0.1≤y1≤3，1.32e^(-10.7b)≤y2≤5.95e^(-14.1b)，并且0.3≤y2≤4），因此，随着使用时间的累积，传统的显示面板中的红色像素、绿色像素、蓝色像素中的任意两者的光效衰减程度的差值会越来越大，导致传统的显示面板的色偏程度（值）会逐渐往预定范围（关于显示效果的数值范围）外发散（即，偏离），也就是说，传统的显示面板的显示效果会越来越差。
而在本发明的显示面板中，由于0.78e^(-1.98r)≤y1≤2.297e^(-1.85r)，并且0.1≤y1≤3，1.32e^(-10.7b)≤y2≤5.95e^(-14.1b)，并且0.3≤y2≤4，因此，在与传统的显示面板的使用时间相同的情况下，本发明的显示面板中的红色像素、绿色像素、蓝色像素中的任意两者的光效衰减程度的差值相差不大，本发明的显示面板的色偏程度（值）仍处于预定范围内，从而，本发明的显示面板保持较好的显示效果的持续时间比传统的显示面板保持相同的显示效果的持续时间要长。
在所述像素重复单元包括一第一像素101、一第二像素102、一第三像素103的情况下，所述第一像素101的开口率=一所述第一像素101的面积/所述像素重复单元的面积，所述第二像素102的开口率=一所述第二像素102的面积/所述像素重复单元的面积，所述第三像素103的开口率=一所述第三像素103的面积/所述像素重复单元的面积。

在所述像素重复单元包括一第一像素101、一第二像素102、两第三像素103的情况下，所述第一像素101的开口率=一所述第一像素101的面积/所述像素重复单元的面积，所述第二像素102的开口率=一所述第二像素102的面积/所述像素重复单元的面积，所述第三像素103的开口率=两所述第三像素103的面积/所述像素重复单元的面积。
在所述第一像素101的形状为椭圆形的情况下，所述第一像素101的面积与所述第一像素101的长轴的长度和短轴的长度对应；在所述第一像素101的形状为圆形的情况下，所述第一像素101的面积与所述第一像素101的半径的长度对应。
在所述第二像素102的形状为包括外凸弧线和/或内凹弧线的形状的情况下，所述第二像素102的面积=所述第二像素102的最小外接圆的面积-像素间隙区与所述第二像素102的第一重合面积；其中，所述像素间隙区包括所述第一像素101与所述第二像素102之间的第一间隙区、所述第二像素102与所述第三像素103之间的第二间隙区中的至少一者。
所述第一重合面积与所述第一像素101与所述第二像素102之间的距离、所述第一间隙区的宽度、所述第一间隙区外周边缘线的曲率对应，以及与所述第三像素103与所述第二像素102之间的距离、所述第二间隙区的宽度、所述第二间隙区外周边缘线的曲率对应。
在所述第三像素103的形状为包括内凹弧线或内凹弧线与外凸弧线的组合的形状的情况下，所述第三像素103的面积等于所述第三像素103的最小外接圆的面积-像素间隙区对与所述第三像素103的第二重合面积；其中，所述像素间隙区包括所述第三像素103与所述第一像素101之间的第三间隙区、所述第二像素102与所述第三像素103之间的第二间隙区中的至少一者。
所述第二重合面积与所述第一像素101与所述第三像素103之间的距离、所述第三间隙区的宽度、所述第三间隙区外周边缘线的曲率对应，以及与所述第三像素103与所述第二像素102之间的距离、所述第二间隙区的宽度、所述第二间隙区外周边缘线的曲率对应。
特别地，所述第一像素101的形状为椭圆形，所述第二像素102的形状和所述第三像素103的形状均为由外凸弧线和/或内凹弧线构成的形状，并且，所述第一像素101的面积、所述第二像素102的面积、所述第三像素103的面积中的任意两者不相同，所述第二像素102的形状与所述第三像素103的形状不相同，所述第二像素102的尺寸与所述第三像素103的尺寸不相同。
在所述第一像素101的形状为椭圆形的情况下，所述椭圆形的长轴与短轴的比值处于1至5的范围内，例如，该比值为1、1.3、1.6、1.8、2、2.3、2.5、2.8、3、3.3、3.5、3.8、4、4.3、4.5、4.8、5中的一者。优选地，所述椭圆形的长轴与短轴的比值处于1至3的范围内。
由于红色像素、绿色像素、蓝色像素的开口率（面积）根据其发光效率而设置，因此，作用在不同像素上的电流密度相等，进而可以避免在长时间显示图像（发光）后，显示面板的色偏程度超出预定范围（即，使得显示面板的色偏程度保持在预定范围）。
由于所述第一像素101、所述第二像素102、所述第三像素103中的至少一者的形状为由外凸弧线构成的形状，所述第一像素101、所述第二像素102、所述第三像素103中的其余至多两者由外凸弧线和内凹弧线构成，并且所述第一像素101、所述第二像素102和所述第三像素103中的两者的边缘部的形状在第一方向D1、第二方向D2、第三方向D3、第四方向D4中的一者上互补，因此，在所述第一像素101、所述第二像素102和所述第三像素103中的任意两者之间必须具有相当宽度的间隙，以防止两像素之间出现干扰的前提下，上述技术方案可以充分利用显示面板10的空间，减小了多余的空间，使得所述第一像素101、所述第二像素102和所述第三像素103的开口率得以提升。
由于所述第一像素101朝向所述第二像素102、所述第三像素103中的一者的边缘部的形状的曲率半径与预定间隙的宽度之和等于所述内凹弧线的曲率半径，因此可以有效提高所述第一像素101、所述第二像素102、所述第三像素103的开口率。
由于所述由外凸弧线和/或内凹弧线构成的形状中的两内凹弧线由外凸弧线连接，因此便于相应的掩模板中的制作（降低掩模板的制作难度），同时有利于提高所述第一像素101、所述第二像素102、所述第三像素103的开口率。
在上述技术方案中，由于所述第一像素的面积、所述第二像素的面积、所述第三像素的面积分别与所述第一像素的发光材料的发光效率、所述第二像素的发光材料的发光效率、所述第三像素的发光材料的发光效率呈反比，因此本发明能避免显示面板出现色偏的问题。
