有机发光二极管(Organic Light-Emitting Diode；OLED)是主动发光器件。与传统的液晶显示(Liquid Crystal Display；LCD)显示方式相比，OLED显示技术无需背光灯，具有自发光的特性。OLED采用较薄的有机材料膜层和玻璃基板，当有电流通过时，有机材料就会发光。因此OLED显示面板能够显著节省电能，可以做得更轻更薄，比LCD显示面板耐受更宽范围的温度变化，而且可视角度更大。OLED显示面板有望成为继LCD之后的下一代平板显示技术，是目前平板显示技术中受到关注最多的技术之一。

具体实施方式
为了更好地理解本申请，下面结合图1至图11根据本申请实施例的电像素排布结构、显示面板、电子设备和掩模组件进行详细描述。
请一并参阅图1至图3，像素排布结构包括呈阵列排布的多个重复单元100，重复单元100呈四边形而具有两条对角线。重复单元100包括四个像素组110，各像素组110分别位于重复单元100的两对角线围合形成的区域内。即各像素组110分别位于重复单元100的两对角线定义的区域内，也即即各像素组110分别位于重复单元100的两对角线与其边缘围合形成的区域内。各像素组110包括一第一发光像素组111、一第二发光像素组112及一备用像素组113。第一发光像素组111包括沿一条对角线排列的至少一个第一子像素101和至少一个第二子像素102。第二发光像素 组112包括沿另一对角线排列的至少一个第一子像素101和至少一个第三子像素103。第一发光像素组111内的第一子像素101和第一发光像素组111的第一子像素101数量相同并关于一对称线L对称分布。第一发光像素组111内的第二子像素102和二发光像素组110内的第三子像素103数量相同且关于对称线L对称分布。备用像素组113与重复单元100的边缘邻接、并位于第一发光像素组111与第二发光像素组112之间。备用像素组113至少包括第二备用子像素102’和第三备用子像素103’。第二备用子像素102’和第二子像素102的发光颜色相同，第三备用子像素103’与第三子像素103的发光颜色相同。
如图2所示，例如重复单元100的其中一条对角线为第一对角线L 1，另一对角线为第二对角线L 2，第一发光像素组111包括沿第一对角线L 1排列的第一子像素101和第二子像素102，第二发光像素组112包括沿第二对角线L 2排列的第一子像素101和第三子像素103。
第一发光像素组111包括沿第一对角线L 1排列的第一子像素101和第二子像素102，第二发光像素组112包括沿第二对角线L 2排列的第一子像素101和第三子像素103，使得第一发光像素组111和第二发光像素组112能够在像素组110所在的区域较为均匀的分布。且当第一子像素101、第二子像素102和第三子像素103以上述方式沿对角线排布时，能够避免第一子像素101、第二子像素102和第三子像素103在第一方向上形成明显的显示条纹。
备用像素组113位于第一发光像素组111和第二发光像素组112之间，令备用像素组113与第一发光像素组111和第二发光像素组112之间的距离均较近。备用像素组113包括与第二子像素102发光颜色相同的第二备用子像素102’、及与第三子像素103发光颜色相同的第三备用子像素103’。当像素排布结构用于显示面板，显示面板用于显示画面时，备用像素组113中的子像素可以作为补偿像素，通过调用第二备用子像素102’和第三备用子像素103’能够拓宽显示面板的色域，使得画面显示更加精细。因此本申请实施例能够拓宽显示面板的色域，提高显示面板的显示效果。
第一子像素101、第二子像素102和第三子像素103的设置方式有多 种，例如第一子像素101为蓝色子像素，第二子像素102为红色子像素，第三子像素103为绿色子像素。在其他实施例中，第一子像素101还可以为红色子像素或者绿色子像素，第二子像素102还可以为蓝色子像素和绿色子像素，第三子像素103还可以为蓝色子像素和红色子像素，只要第一子像素101、第二子像素102和第三子像素103为颜色互不相同的子像素即可。
可选的，第一子像素101为蓝色子像素，第一发光像素组111和第二像素组110内均设置有第一子像素101。蓝色子像素的发光效率通常低于绿色子像素和红色子像素，第一子像素101为蓝色子像素，能够增大蓝色子像素的面积，提高蓝色子像素的整体使用寿命。
在一些可选的实施例中，第一发光像素组111内第一子像素101和第二子像素102的个数比为1:1，第二发光像素组112内第一子像素101和第三子像素103的个数比为1:1。那么像素组110内第一子像素101、第二子像素102和第三子像素103的个数比为2:1:1。第一子像素101的个数较多，能够提高第一子像素101的分布面积，提高第一子像素101的使用寿命。例如，当第一子像素101为蓝色子像素时，如上所述，能够提高蓝色子像素的个数，提高蓝色子像素的使用寿命。
像素组110内各子像素的排布方式有多种，在一些可选的实施例中，第一发光像素组111内第一子像素101和第二子像素102的个数均为两个，两个第一子像素101沿第一对角线L 1间隔分布，两个第二子像素102沿第一对角线L 1分布并位于两个第一子像素101之间。第二发光像素组112内第一子像素101和第三子像素103的个数均为两个，两个第一子像素101沿第二对角线L 2间隔分布，两个第三子像素103沿第二对角线L 2分布并位于两个第一子像素101之间。
当多个子像素以上述方式排布时，第一发光像素组111内的至少一个第一子像素101与第二发光像素组112内的一个第一子像素101相邻设置，且该两个第一子像素101靠近第一对角线L 1和第二对角线L 2的交点设置，使得该两个第一子像素101能够通过蒸镀掩膜板的同一开口蒸镀成型，降低金属掩膜板制程压力。
此外，当两个第二子像素102沿第一对角线L 1排布，两个第三子像素103沿第二对角线L 2排布，令两个第二子像素102和两个第三子像素103之间能够留有一定的间隙，为备用像素组113提供让位。
重复单元100可呈矩形，重复单元100沿第一方向和第二方向阵列排布。像素排布的结构较为简单。
第一方向和第二方向的设置方式有多种，第一方向和第二方向可以以任意预设角度相交设置。在一些可选的实施例中，第一方向和第二方向之间的夹角呈90度，如图1中所示的X轴(第一方向)和Y轴(第二方向)，因此各重复单元100可以沿水平和竖直方向横平竖直的排布，结构简单，制造方便。此外重复单元100呈矩形，重复单元100沿X轴和Y轴阵列分布还能够减小相邻两个重复单元100之间的间距，提高像素排布结构的像素密度。
可选的，四个像素组110环绕两条对角线交点分布，以使同一重复单元100的相邻两个像素组110内，其中一个像素组110的第一发光像素组111与另一像素组110的第二发光像素组112相邻并位于同一对角线的两侧。
当四个像素组110环绕对角线的交点分布，且令位于不同像素组110内的第一发光像素组111和第二发光像素组112相邻并位于同一对角线的两侧，能够减小不同像素组110内的第一发光像素组111和第二发光像素组112中第一子像素101、第二子像素102和第三子像素103之间的间距，提高该第一发光像素组111和第二发光像素组112中第一子像素101、第二子像素102和第三子像素103形成的显示单元的显示效果。
另一方面，当四个像素组110环绕对角线的交点分布时，第一发光像素组111和第二发光像素组112内靠近对角线交点设置的第一子像素101环绕该交点分布，使得四个像素组110内八个第一子像素101环绕该交点分布，八个第一子像素101相邻设置，使得八个第一子像素101能够通过同一个掩膜板的蒸镀开口蒸镀成型。
此外，当重复单元100沿第一方向和第二方向阵列排布时，位于重复单元100的两条边缘相交位置的两个第一子像素101能够与其他重复单元 100的第一子像素101相邻设置。例如位于重复单元100的两条边缘相交位置的两个第一子像素101能够与其他三个重复单元100中相同位置的两个第一子像素101相邻设置，该八个第一子像素101也能够通过掩膜板的同一个蒸镀开口蒸镀成型。
因此在本申请实施例提供的像素排布结构中，八个第一子像素101相邻设置，八个第一子像素101能够通过掩膜板的同一个蒸镀开口蒸镀成型。
像素排布结构进行显示的方式有多种，例如在一些可选的实施例中，位于同一对角线两侧的第一发光像素组111和第二发光像素组112中：四个第一子像素101、两个第二子像素102和两个第三子像素103形成一个低像素显示单元120，第一发光像素组111和第二发光像素组112形成一个低像素显示单元120；或者，一个第一子像素101、一个第二子像素102和一个第三子像素103形成一个高像素显示单元130，相邻的两个高像素显示单元130共用第二子像素102和第三子像素103，第一发光像素组111和第二发光像素组112形成四个高像素显示单元130。
图1中以虚线示意出低像素显示单元120和高像素显示单元130，虚线并不构成对本申请实施例提供的像素排布结构的结构上的限定。
第一发光像素组111和第二发光像素组112共包含四个第一子像素101、两个第二子像素102和两个第三子像素103。四个第一子像素101、两个第二子像素102和两个第三子像素103可以形成一个低像素显示单元120，第一发光像素组111和第二发光像素组112形成一个低像素显示单元120，使得像素排布结构能够实现低像素显示。且在低像素显示单元120中第一子像素101、第二子像素102和第三子像素103不存在共用的情况，能够保证像素排布结构在低像素显示状态下具有良好的显示效果。
该第一发光像素组111和第二发光像素组112中的四个第一子像素101、两个第二子像素102和两个第三子像素103也能够形成四个高像素显示单元130，实现像素排布结构的高像素显示。相邻的两个高像素显示单元130共用第二子像素102和第三子像素103，能够在保证像素密度的同时减少第二子像素102和第三子像素103的个数，提高像素开口率，增 大第二子像素102和第三子像素103的面积，进而增大掩膜板上对应于第二子像素102和第三子像素103的蒸镀开口面积，能够简化掩膜板的结构。
因此本申请实施例提供的像素排布结构既能够实现低像素显示，保证低像素显示具有良好的显示效果；也能够实现高像素显示，并不会给工艺带来太大的难度。
如上所述，两个第二子像素102和两个第三子像素103之间能够留有一定的间隙，备用像素组113设置与该间隙内。备用像素组113在该间隙内的设置方式有多种，备用像素组113内第二备用子像素102’与第二子像素102相邻设置，使得第二备用子像素102’和两个第二子像素102能够共用一个掩膜板的蒸镀开口蒸镀成型。可选的，第三备用子像素103’与第三子像素103相邻设置，以使第三备用子像素103’能够与第三子像素103共用一个开口蒸镀成型。
备用像素组113的设置方式有多种，请继续参阅图1至图3，备用像素组113包括一个第二备用子像素102’和一个第三备用子像素103’。
在上述实施例中，重复单元100的形状为正方形，使得重复单元100的形状更加规则，同时也使得各像素组110在重复单元100内的分布面积更加平均。
当重复单元100为正方形时，靠近两条对角线交点设置的八个第一子像素101例如呈正方形分布，掩膜板上用于蒸镀第一子像素101的开口呈正方形，能够简化掩膜板的成型工艺。
进一步可选的，重复单元100中位于其两条边缘交点处的两个第一子像素101呈等腰直角三角形分布。当重复单元100沿第一方向和第二方向阵列分布时，四个重复单元100上位于其两条边缘交点处的两个第一子像素101相邻设置，该八个第一子像素101也能够呈正方形分布。
可选的，第一发光像素组111内的两个第一子像素101对称分布，第一发光像素组111内的两个第一子像素101尺寸相同。使得像素排布结构中不同位置的八个第一子像素101的尺寸相同，用于蒸镀第一子像素101的掩膜板上的蒸镀开口的尺寸均相同。

可选的，第二备用子像素102’和第三备用子像素103’关于对称线L对称分布，使得备用像素组113内各子像素的排布更加规律，像素排布结构显色更加均匀。

备用像素组113还包括与第一子像素101发光颜色相同的第一备用子像素101’，第一备用子像素101’能够对第一子像素101的发光颜色进行补光，改善备用像素组113的补光效果，进一步提升像素排布结构的色域。
当重复单元100沿第一方向和第二方向阵列排布时，沿第一方向和/或第二方向相邻的两个重复单元100中，至少两个备用像素组113中的第一备用子像素101’相邻设置，以使相邻的两个第一备用子像素101’能够共用一个蒸镀开口蒸镀成型。
可选的，重复单元100呈正方形，像素组110呈等腰直角三角形，像素组110关于对称线L对称。使得重复单元100内各子像素的排布更加规律均匀，提高像素排布结构的显示效果。
