附图中各部件的形状和大小不反映本公开实施例的像素排布结构、有机电致发光显示面板、金属掩模板及显示装置的各个膜层和部件的真实比例，目的只是示意说明本公开实施例内容。
根据本公开的实施例的总体发明构思，提供了一种像素排布结构、有机电致发光显示面板、金属掩模板及显示装置，旨在解决相关OLED器件中存在的像素之间的距离较大的问题。
在本公开的实施例的一方面，提供一种像素排布结构，如图1所示，包括：每个像素排布结构包括如图1所示的位置互不重叠即彼此间隔开的多个子像素，所述多个子像素包括第一子像素01，多个第二子像素02和多个第三子像素03；其中，具体地，例如，所述多个第一子像素01之一布置成在所有的多个子像素中居于中心，且其它四个第一子像素布置成围绕居于中心的所述第一子像素分别充当顶点以限定第一虚拟矩形；换言之，所述多个第一子像素01分别位于第一虚拟矩形的中心处和第一虚拟矩形的四个顶角位置处；且所述第一虚拟矩形包括布置呈2*2矩阵且镜像对称的四个第二虚拟矩形；
所述多个第二子像素02分别位于第一虚拟矩形的各侧边中心位置处，并且由位于每个所述第一虚拟矩形相邻两个侧边各自中心位置处的两个所述第二子像素02、与 该两个所述第二子像素02均相邻且分别位于每个所述第一虚拟矩形的中心处和所述第一虚拟矩形的一顶角位置处的所述第一子像素01分别充当每个第二虚拟矩形的四个顶点；
所述多个第三子像素03分别位于所述第二虚拟矩形内，且所述多个第三子像素03中每个的形状例如为凹多边形或包括曲线的图形。
具体地，如上所述的本公开的实施例提供的上述像素排布方式与相关的像素排布结构相比，在同等工艺条件下例如使第一子像素01、第二子像素02和第三子像素03紧密排列，尽可能的减小相邻像素之间的间距。并且，将第三子像素03的形状设置为凹多边形(所述凹多边形的定义为，即将该多边形的任一侧边向其两端无限延长为直线，其它侧边并非在此直线的同侧)、或由多条连续的线(例如连续的曲线，或包括曲线在内的多条连续线)构成的封闭图形(这些封闭形状例如是由多条平滑的连续线构成因而无法分类为凹多边形或凸多边形)，由此进一步减小第三子像素03与相邻第一子像素01之间的间距，以及减小第三子像素03与相邻第二子像素02之间的间距。从而在同等分辨率的条件下增大像素开口面积，降低显示器件的驱动电流，抑制器件的老化速度，进而增加显示器件的寿命。
具体地，本公开的实施例提供的上述像素排布结构中，第三子像素03的形状为凹多边形指的是非传统意义上的五边形、六边形、菱形等的凸多边形(所述凸多边形的定义为，即将该多边形的任一侧边向其两端无限延长为直线，其它侧边均在此直线的同侧)，而是一些不规则形状的图形例如图9a所示示意出的各种形状，并且这些形状例如是对称图形，或例如是不对称图形，在此不做限定。并且，凹多边形的某个侧边例如是呈平直线段、曲线或折线(fold line)。更具体地，本公开实施例中所述凹多边形例如限定为如下图形：在该图形包括至少某个侧边为曲线或折线、其余侧边为平直线段的情况下，对于该图形，若将呈曲线或折线的侧边分别在其两端点处沿着曲线的切线或沿着该折线无限延长，则其他侧边并非全都在这种已延长线(extended line)的同侧；并且，若将呈平直线段的侧边分别在其两端点处沿着其本身无限延长，则其他侧边也并非全都在这种已延长线(extended line)的同侧。
在额外或替代的实施例中，第三子像素03的形状为由包括曲线在内的多条连续的线构成的封闭图形，所述曲线的形状为如下之一：内凹的、外凸的、曲折起伏的。如图9b所示，例如是圆形，椭圆，类圆形(quasi-circular)，类椭圆形(quasi-elliptic)形状，或其他包括曲线的形状等，例如是由部分曲线和部分直线构成的图形，在此不 做限定。
需要说明的是，在本公开的实施例提供的上述像素排布结构中，提到的像素位于某一位置处，是指像素所在的位置范围，只要保证像素与该位置有重叠即可。在具体实施时，例如使像素的中心与该位置重叠，当然，像素的中心也例如与该位置不重叠，即两者存在偏移，在此不作限定。在具体的实施例中，例如，在所述像素排布结构中，像素位于某一位置处意思是像素在衬底基板上的投影至少部分地与所述位置在衬底基板上的投影区域重叠。
并且，像素的中心例如是像素图形的几何中心，也例如是像素发光颜色的中心，在此不做限定。
例如，在本公开的实施例提供的上述像素排布结构中，为了保证各像素能够均匀分布，尽量使各像素的中心靠近所对应的位置。例如，在一种实施例中，在所述像素排布结构中，位于某位置的像素被设置成使得：像素在衬底基板上的投影完全地与所述位置在衬底基板上的投影区域重叠。
需要说明的是，在本公开的实施例提供的显示排布结构中提到的第一虚拟矩形为图1中最大的虚线框，第二虚拟矩形为图1中小的虚线框，在图1中第一虚拟矩形包括四个第二虚拟矩形，第一虚拟矩形和第二虚拟矩形例如是长方形，也例如是正方形，在此不做限定。
例如，在本公开的实施例提供的上述像素排布结构中，如图1至图6所示，第三子像素03的形状为凹四边形，且至少一个侧边为内凹的曲线或折线。具体地，将凹四边形的侧边设置为内凹的曲线或折线导致适当的减小第三子像素的开口面积，相应地在所述每个像素排布结构内留出更多空间用以增大第一子像素01和第二子像素02的开口面积，从而提升产品寿命。
例如，在本公开的实施例提供的上述像素排布结构中，第三子像素03的形状具体例如包括：如图1、图2、图3、和图5所示的四个侧边均为内凹的四边形，或如图4所示的相对的两个侧边为内凹且另两个相对侧边为外凸的四边形的至少一种。
例如，在本公开的实施例提供的上述像素排布结构中，如图1、图2和图5所示，四个侧边均为内凹的四边形中，至少一个内凹侧边例如是曲线；在具体实施例中，若将每个呈曲线的内凹侧边分别在其两端点处沿着曲线的切线无限延长，则其它侧边并非全都在由此所得到的已延长线的同侧。在替代的实施例中，如图3所示，四个侧边均为内凹的四边形中，至少一个内凹侧边例如是折线；在具体实施例中，若将每个呈 折线的内凹侧边分别在其两端点处沿着折线无限延长，则其它侧边并非全都在由此所得到的已延长线的同侧。
具体地，图1、图2和图5中第三子像素03的凹四边形的四个内凹侧边均为曲线；图3中第三子像素03的凹四边形的四个内凹侧边均为折线。在实际应用时，例如存在凹四边形的部分侧边为曲线部分侧边为折线的情况。
例如，在本公开的实施例提供的上述像素排布结构中，如图4所示，相对的两个侧边为内凹且另两个相对侧边为外凸的四边形中，至少一个内凹侧边例如是曲线或折线，且至少一个外凸侧边为曲线或折线。并且，第三子像素03的凹四边形形状还替代地例如为一个、相邻的两个或三个侧边为内凹，其他侧边为外凸的情况，在此不做限定。具体地，例如，图4中第三子像素03的内凹侧边和外凸侧边均为曲线。在实际应用时，例如存在一个内凹侧边为曲线，一个内凹侧边为折线，一个外凸侧边为曲线，一个外凸侧边为折线等的情况，在此不做限定。
例如，在本公开的实施例提供的上述像素排布结构中，第三子像素03的凹四边形具有的折线或曲线侧边的曲率，所呈的外凸或内凹的具体形态，以及弯折程度例如根据第一子像素01和第二子像素02的形状进行调整。
例如，在本公开的实施例提供的上述像素排布结构中，在所述多个第三子像素中至少一个的形状为包括曲线的图形的情况下，所述包括曲线的图形例如包括以下图形：圆形，椭圆形，类圆形(quasi-circular)，和类椭圆形(quasi-elliptic)形状等，或者其他包括曲线的形状等，例如是由部分曲线和部分直线构成的图形，在此不做限定。
例如，在本公开实施例提供的上述像素排布结构中，所述多个第三子像素例如至少一个为椭圆形。在示意性的实施例中，例如，如图10所示，所述多个第三子像素例如均为椭圆形，并且呈椭圆形的所述多个第三子像素分别布置成以各自椭圆形的长轴与各自所在的第二虚拟矩形的指向第一虚拟矩形的中心的对角线重合，相应地即各自椭圆形的短轴与各自所在的第二虚拟矩形的指向第一虚拟矩形的中心的对角线垂直。
例如，在本公开的实施例提供的上述像素排布结构中，第三子像素03与其所面对的相邻的第一子像素01的侧边之间的最小距离需要大于或等于工艺极限距离，第三子像素03与其所面对的相邻的第二子像素02的侧边之间的最小距离需要大于或等于工艺极限距离，以满足工艺需求。在本公开的实施例中，两个侧边之间的距离，是指一个侧边上的各点到另一侧边上的各点之间的一系列距离的集合，下文同此定义。
例如，在本公开的实施例提供的上述像素排布结构中，第三子像素03与相邻第 一子像素01中其面对的侧边之间的最大距离和最小距离的比值范围为1～1.5，具体地，第三子像素03与相邻第一子像素01中其面对的侧边之间的最大距离与最小距离之间的比值的范围为0.8至1.2，更具体地为0.9～1.1，比如例如是1.1，1.2，1.3或1.4，甚至比例为1(即第三子像素03与相邻第一子像素01中其面对的侧边之间的最大距离与最小距离相等，定义为第三子像素03与相邻第一子像素01二者的彼此面对的侧边彼此平行，下文中的平行同样地如此定义，即两个彼此面对的侧边之间的最大距离等于最小距离)。同样，第三子像素03与相邻第二子像素02二者的彼此面对的侧边之间的最大距离和最小距离的比值范围为1～1.5，具体地，比如例如是1.1，1.2，1.3或1.4。并且，第三子像素03与相邻第一子像素01(或相邻第二子像素02)二者的彼此面对的侧边之间的最大距离和最小距离的比值范围大于1时，这表明彼此面对的侧边的形状并不一致
例如，在本公开的实施例提供的上述像素排布结构中，为了保证第三子像素03与相邻的第一子像素01之间的间隙宽度一致，以减小第三子像素03与相邻第一子像素01之间的间距，如图1和图2所示，在第三子像素03与相邻第一子像素01(或相邻第二子像素02)二者的彼此面对的侧边之间的最大距离和最小距离的比值始终为1时，这表明彼此面对的侧边的形状完全匹配，且两个面对的侧边之间间距始终保持相等，由此称为第三子像素03的边缘例如布置成与相邻第一子像素01二者的彼此面对的侧边二者彼此相互平行，即定义为二者间例如相互等距地间隔开。并且，例如具体地通过将第三子像素03与相邻第一子像素01相对的侧边二者的形状设置为互补图形从而使得它们彼此相对的部分的边缘呈形状匹配(shaped to be in positive fit)的曲线或折线段，来实现相互平行。当然，在具体实施时，第三子像素03与相邻第一子像素01二者的彼此面对的侧边也例如不平行，在此不做限定。
例如，在本公开的实施例提供的上述像素排布结构中，为了保证第三子像素03与相邻的第二子像素02之间的间隙宽度一致，以减小第三子像素03与相邻第二子像素02之间的间距，如图1和图2所示，第三子像素03与相邻第二子像素02二者的彼此面对的侧边例如相互平行，如前所定义。并且，例如通过将第三子像素03与相邻第二子像素02二者的彼此面对的侧边二者的形状设置为互补图形从而使得它们彼此相对的部分的边缘呈完全相同地匹配的曲线或折线段，来实现相互平行。当然，在具体实施时，第三子像素03与相邻第二子像素02二者的彼此面对的侧边也例如不平行，在此不做限定。
例如，在本公开的实施例提供的像素排布结构中，第三子像素03与第一子像素01之间的最小间距，和第三子像素03与第一子像素01之间的最小间距例如是相等的。
例如，在本公开的实施例提供的像素排布结构中，任意相邻两个第一子像素与第二子像素之间的最小间距例如是相等的。
并且，最小间距一般为工艺极限距离，最小间距的数值范围通常与所使用的制作工艺有关，采用高精度金属掩模板(FMM)配合刻蚀工艺形成像素图形时，该最小间距约在16μm左右，采用激光或电铸等工艺形成像素图形时，该最小间距会更小。
例如，在本公开的实施例提供的上述像素排布结构中，为了使第三子像素03能够在该像素排布结构中均匀分布，以减小第三子像素03与相邻第一子像素01之间的间距，以及减小第三子像素03与相邻第二子像素02之间的间距，如图2至图6所示，则第三子像素03例如位于第二虚拟矩形内的相邻两个第一子像素01的连线和相邻两个第二子像素02的连线的交点位置处。
例如，第二子像素02、第一子像素01和第三子像素03的具体形状，位置关系，平行及角度关系等，例如根据需要进行设计，在实际工艺中，由于工艺条件的限制或其他因素，也会有一些偏差，因此各子像素的形状、位置及相对位置关系只要大致满足上述条件即可，均属于本公开的实施例提供的像素排布结构。
例如，在本公开的实施例提供的上述像素排布结构中，第一子像素01例如是红色子像素，第二子像素02例如是蓝色子像素；或，第一子像素01例如是蓝色子像素，第二子像素02例如是红色子像素；第三子像素03为绿色子像素。这样如图7所示，位于第二虚拟矩形中心的绿色子像素G例如与位于其所在的第二虚拟矩形任意相邻两个角上的红色子像素R和蓝色子像素B构成一个发光像素点，即每个第二矩形网格形状形成为一个发光像素点。
进一步地，以下以示意性方式对单个子像素面积进行讨论。
由于人眼对绿光比较敏感，因此，例如，在本公开的实施例提供的像素排布结构中，如图1至图6所示，第三子像素03的面积例如小于第一子像素01的面积，且第三子像素03的面积例如小于第二子像素02的面积。即绿色子像素的面积小于红色子像素的面积，绿色子像素的面积小于蓝色子像素的面积，换言之，在一种实施例中，作为人眼较为敏感的颜色的绿色子像素的面积例如设置为最小。
另外，例如，在本公开的实施例提供的上述像素排布结构中，第二子像素02的面积与第一子像素01的面积例如相同，即红色子像素的面积与蓝色子像素的面积相同。 或者，第二子像素02的面积与第一子像素01的面积也例如不同，即红色子像素的面积与蓝色子像素的面积不同，在此不做限定。一般地，蓝色子像素的发光效率和寿命都低于红色子像素，因此，例如将蓝色子像素的面积设置为大于红色子像素的面积。由此，例如，就单个子像素的面积而言，例如存在如下设置：在一个实施例中，例如，蓝色子像素的面积大于红色子像素的面积、进而红色子像素的面积大于绿色子像素的面积；或者在替代实施例中，例如，蓝色子像素的面积大于绿色子像素的面积、进而绿色子像素的面积大于或等于红色子像素的面积。
例如，在本公开的实施例提供的上述像素排布结构中，如图1至图5所示，各第三子像素03的面积例如相同。从而保证在由第一子像素01、第二子像素02和第三子像素03组成的任意发光像素点中，第三子像素03的发光面积均相同。
当然，在具体实施时，在本公开的实施例提供的上述像素排布结构中，如图6所示，也例如有至少两个第三子像素03的面积不相同，在此不作限定。
例如，在本公开的实施例提供的上述像素排布结构中，如图1至图4所示，各第一子像素01的面积例如相同。从而保证在由第一子像素01、第二子像素02和第三子像素03组成的任意发光像素点中，第一子像素01的发光面积均相同。
当然，在具体实施时，在本公开的实施例提供的上述像素排布结构中，如图5和图6所示，也例如有至少两个第一子像素01的面积不相同，在此不作限定。
例如，在本公开的实施例提供的上述像素排布结构中，如图1至图4所示，各第二子像素02的面积例如相同。从而保证在由第一子像素01、第二子像素02和第三子像素03组成的任意发光像素点中，第二子像素02的发光面积均相同。
当然，在具体实施时，在本公开的实施例提供的上述像素排布结构中，如图5和图6所示，也例如有至少两个第二子像素02的面积不相同，在此不作限定。
并且，在本公开的实施例中，关于各种子像素的面积，例如，在单个像素排布结构中，分别充当红色子像素、绿色子像素和蓝色子像素的单个第一子像素01的面积例如下文称为S 01、单个第三子像素03的面积例如下文称为S 03、和单个第二子像素02的面积例如下文称为S 02。
相应地，例如，在本公开的实施例中，在单个像素排布结构中，在红色子像素、绿色子像素和蓝色子像素各自的合计面积比较中，例如，由于分别充当红色子像素、绿色子像素和蓝色子像素的第一子像素01、第三子像素03、和第二子像素02的数量为5个、4个、4个，则相应地，在单个像素排布结构中，三种子像素各自的合计面积 相应地分别为：在单个像素排布结构中，红色子像素合计面积为S 01*5，绿色子像素合计面积为S 03*4：蓝色子像素合计面积为S 02*4。并且，在单个第一虚拟矩形中，三种子像素各自的合计面积之间比例例如具体如下：分别充当红色子像素(R)、绿色子像素(G)和蓝色子像素(B)的第一子像素01、第三子像素03、和第二子像素02各自的合计面积之比例如为1:(1.1～1.5):(1.2～1.7)，进一步的例如为1:(1.2～1.35):(1.4～1.55)，进一步的例如为1:1.27:1.46。
并且，以下以示意性方式对子像素的形状和排布规律进行讨论。
为了保证在制备时，对于同一种像素，掩膜图案能够一致，从而能够简化构图工艺，例如，在本公开的实施例提供的像素排布结构中，如图1至图5所示，各第三子像素03的形状例如一致。
或者，例如，在本公开的实施例提供的上述像素排布结构中，也例如至少两个第三子像素03的形状不一致，在此不作限定。
例如，在本公开的实施例提供的上述像素排布结构中，如图6所示，位于第一虚拟矩形的一条对角线方向上的两个第三子像素03的形状相同，位于第一虚拟矩形的另一条对角线方向上的两个第三子像素03的形状相同，而位于第一虚拟矩形不同对角线方向的第三子像素的形状则彼此不同。或者，也例如位于第一虚拟矩形内的四个第三子像素03的形状各不相同，在此不做限定。
并且，例如，在本公开的实施例提供的上述像素排布结构中，在一个第一虚拟矩形中，四个第三子像素03图形相同或相似时，其排布角度例如相同，也例如如图1至图7所示，构成第一虚拟矩形的四个第二虚拟矩形中的四个第三子像素呈“X”状分布，即四个第三子像素03为长条状且均指向第一虚拟矩形的中心；或者，在一个第一虚拟矩形中，四个第三子像素03的图形例如关于竖直中心线呈左右对称，或关于水平中心线呈上下对称。或者，四个第三子像素03图形的角度还例如任意旋转，在此不做限定。
具体地，在位于构成所述第一虚拟矩形的四个所述第二虚拟矩形中的四个所述第三子像素呈“X”状分布的情况下，在一个实施例中，例如如图1、图2、图3和图5所示，在分别与所述第一虚拟矩形的两条对角线平行的两个方向上，所述第三子像素的侧边均为内凹的。在另一实施例中，例如如图4、图6所示，至少在与所述第一虚拟矩形的两条对角线之一平行且指向所述第一虚拟矩形的中心的方向上延伸的至少两个所述第三子像素03的朝向和远离所述第一虚拟矩形中心的侧边为凹入的。
为了保证在制备时，对于同一种像素，掩膜图案能够一致，从而能够简化构图工艺，例如，在本公开的实施例提供的像素排布结构中，如图1至图4所示，各第一子像素01的形状例如一致。
当然，在具体实施时，在本公开的实施例提供的上述像素排布结构中，如图5和图6所示，也例如至少两个第一子像素01的形状不一致，在此不作限定。
并且，例如，在本公开的实施例提供的上述像素排布结构中，在一个第一虚拟矩形中，五个第一子像素01图形相同或相似时，其排布角度例如相同，也例如其排布角度任意旋转，在此不做限定。
为了保证在制备时，对于同一种像素，掩膜图案能够一致，从而能够简化构图工艺，例如，在本公开的实施例提供的像素排布结构中，如图1至图4所示，各第二子像素02的形状一致。
当然，在具体实施时，在本公开的实施例提供的上述像素排布结构中，如图5和图6所示，也例如至少两个第二子像素02的形状不一致，在此不作限定。
并且，例如，在本公开的实施例提供的上述像素排布结构中，在一个第一虚拟矩形中，四个第二子像素02图形相同或相似时，其排布角度例如相同，也例如其排布角度任意旋转，在此不做限定。
例如，在本公开的实施例提供的上述像素排布结构中，如图1至图3所示，第一子像素01与第二子像素02的形状例如一致，或者如图4至图6所示，第一子像素01与第二子像素02的形状也例如不一致，在此不作限定。
在具体实施时，在本公开的实施例提供的上述像素排布结构中，第一子像素01和第二子像素02的形状例如呈规则的形状，也例如呈不规则的形状，在此不作限定。一般规则的图形在制作时更容易，因此，例如，在本公开的实施例提供的像素排布结构中，如图1至图6所示，第一子像素01和第二子像素02的形状均为规则图形，例如圆形，椭圆形，如正方形，正六边形，正八边形等的正多边形，以及其他凸多边形，或曲面多边形等，在此不做限定。
需要说明的是，本公开的实施例提到的像素的图形不一致，是指像素的形状不一致，例如一个为圆形，一个为矩形。反之，本公开的实施例提到的像素的图形一致则是指像素的形状相似或相同，例如两个像素的形状均为三角形，不管面积是否相等，则认为该两个指像素的形状一致。
基于同一发明构思，在本公开的实施例的另一方面，还提供了一种有机电致发光 显示面板，如图8所示，包括多个紧密排列的像素排布结构(图8中以4个像素排布结构为例)；该像素排布结构例如是本公开实施例提供的上述任一种像素排布结构，相邻的第一虚拟矩形在行方向和列方向上布置成使得在各自的相面对的侧边上的子像素是共用的。即相邻的两个像素排布结构共用位于各自的相邻第一虚拟矩形的相邻接侧边(例如侧边的角点、侧边中点)处的第一子像素01和第二子像素02，例如图8中每一椭圆圈起来的三个像素为相邻两个像素排布结构共用的像素。更具体地，例如如图8所示，每个第一虚拟矩形右下角的子像素作为其同行的后一个第一虚拟矩形左下角的子像素，以及每个第一虚拟矩形右上角的子像素作为其同行的后一个第一虚拟矩形左上角的子像素；以及每个第一虚拟矩形左下角的子像素作为其同列的后一个第一虚拟矩形的左上角的子像素，每个第一虚拟矩形右下角的子像素作为其同列的后一个第一虚拟矩形的右上角的子像素。由于该有机电致发光显示面板解决问题的原理与前述一种像素排布结构相似，因此该有机电致发光显示面板的实施例如参见前述素排布结构的实施，重复之处不再赘述。
并且，需要指出的是，在本公开的实施例中，在所述有机电致发光显示面板中，由于相邻的第一虚拟矩形在行方向和列方向上布置成在各自的相面对的侧边上的子像素是共用的，换言之，对于所述有机电致发光显示面板中的每个第一虚拟矩形而言，在其侧边和角点处存在邻接的相邻第一虚拟矩形的情况下，这些位置处的其子像素是与相邻第一虚拟矩形共用的，从而使得各个第一虚拟矩形中每单个第一虚拟矩形中三种子像素的合计面积之间比例并不等于在整个所述有机电致发光显示面板中三种子像素各自总面积之间比例。
并且，根据相邻第一虚拟矩形之间共用位于彼此邻接处的侧边和角点位置处的子像素的规律，可知，由于充当绿色子像素(G)的第三子像素03始终位于各自的第一虚拟矩形内部，从而不会在相邻第一虚拟矩形之间共用，因而，对于整个所述有机电致发光显示面板而言，三种子像素各自的总数量之比中绿色子像素所占比例，相比于在单个第一虚拟矩形中三种子像素各自合计数量之比中绿色子像素所占比例会有所提高。
具体地，例如，在整个所述有机电致发光显示面板中三种子像素即分别充当红色子像素(R)、绿色子像素(G)和蓝色子像素(B)的第一子像素01、第三子像素03、和第二子像素02各自总数量之间比例为1：2：1，这显然不同于如前所述的在在单个第一虚拟矩形中三种子像素各自合计数量之比。
具体地，本公开的实施例提供的有机电致发光显示面板，如图8所示，第一子像素01和第二子像素02在行方向上依次交替排列，第一子像素01和第二子像素02在列方向上也依次交替排列，第三子像素01位于由两个第一子像素01和两个第二子像素02围成的第二虚拟矩形内，这样在显示时，任意相邻的两个第一子像素01和第二子像素02均例如和与其相邻的一个第三子像素03组成一个发光像素点，像素之间通过借色原理由低分辨率的物理分辨率实现高分辨率的显示效果。
基于同一发明构思，在本公开的实施例的又一方面，还提供了一种高精度金属掩模板，用于制作本公开的实施例提供的上述像素排布结构，包括：均匀排布的多个开口区域，开口区域与第一子像素，第二子像素或第三子像素的形状和位置对应。
基于同一发明构思，在本公开的实施例的再一方面，还提供了一种显示装置，包括本公开的实施例提供的上述任一种有机电致发光显示面板。该显示装置例如是：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。该显示装置的实施例如参见上述显示面板的实施例，重复之处不再赘述。
本公开的实施例提供的上述像素排布结构、有机发光显示面板、高精度金属掩模板及显示装置，其中在像素排布结构中，包括：位置互不重叠且彼此间隔开多个子像素，所述多个子像素包括多个第一子像素，多个第二子像素和多个第三子像素；其中，所述多个第一子像素之一和其它四个第一子像素分别布置成充当中心和顶点以限定第一虚拟矩形，即，使得第一子像素位于第一虚拟矩形的中心处和第一虚拟矩形的四个顶角位置处；第二子像素位于第一虚拟矩形的侧边中心位置处；第三子像素的形状为凹多边形或由曲线构成的图形且位于第二虚拟矩形内，第二虚拟矩形由位于第一虚拟矩形相邻两个侧边中心位置处的两个第二子像素、与该两个第二子像素均相邻且分别位于第一虚拟矩形的中心处和第一虚拟矩形的一顶角位置处的第一子像素作为顶角顺次相连形成，且四个第二虚拟矩形构成一个第一虚拟矩形。综上所述，本公开实施例的技术方案，具有如下有益效果：这种像素排布方式与相关的像素排布结构相比，在同等工艺条件下例如使第一子像素、第二子像素和第三子像素紧密排列，尽可能的减小相邻像素之间的间距，从而在同等分辨率的条件下增大像素开口面积，降低显示器件的驱动电流，进而增加显示器件的寿命。
显然，本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公 开实施例的精神和范围。这样，若本公开实施例的这些修改和变型属于本公开实施例权利要求及其等同技术的范围之内，则本公开实施例也意图包含这些改动和变型在内。
