背景技术
在手机和平板显示技术中，主动矩阵有机电致发光(Active Matrix Organic Light Emitting Diode，AMOLED)面板由于其自主发光、色彩鲜艳、低功耗、广视角等优点将逐渐成为下一代显示器的主流。
AMOLED自主发光的原理包括：用背板上制作的铟锡氧化物半导体(ITO)电极和金属电极分别作为器件的阳极和阴极，将有机半导体材料和发光材料蒸镀到基板上，在一定电压驱动下，电子和空穴分别从阴极和阳极注入到电子和空穴传输层，电子和空穴分别经过电子和空穴传输层迁移到发光层，并在发光层中相遇，形成激子并使发光分子激发，后者经过辐射弛豫而发出可见光。
目前人们对手机或者平板的分辨率和亮度要求越来越高，但要生产高质量、高分辨率的有机电致发光(Organic Light Emitting Diode，OLED)显示屏，仍然面临重重挑战。对于高分辨率的AMOLED来说，精密金属掩膜板(Fine Metal Mask，FMM)是制约其发展的技术之一，该蒸镀用的金属掩膜板的制作随着分辨率的提高也越来越困难，同时由于分辨率的提高，子像素发光区域之间的距离要求越来越小，蒸镀出来的屏幕混色也会越来越严重，特别是传统的条状排列的红(R)、绿(G)、蓝(B)三个子像素，每个子像素对应的FMM的开口区域的长度较长，直线性控制困难，容易发生混色。而传统的点状(Slot)的RGB排列方式，虽然不会导致开口率长度较长，直线性难以控制，但是在FMM的开口区域的制作过程中，每个Slot的开口区域之间都要留有一定的金属原材料作为连接桥(称为Rib)，从而导致子像素FMM开口区域的大小缩小， 从而影响OLED显示器件的开口率。开口率低，亮度和寿命不能达到要求。从而使AMOLED产品良率低，限制了高分辨率的AMOLED面板量产。

附图说明

具体实施方式
以下根据图1和图2来描述一种像素排列结构。参见图1，该像素排列结构采用slot排列方式，每一像素中包含3个子像素，分别为R、G、B子像素，每一颜色子像素对应的高精细金属掩膜版(FMM)如图2所示，每个FMM开口里面有一个发光区，每一子像素与相邻的不同颜色的子像素之间的距离称为PDL gap，当PDL Gap距离一定时，如图1所示，距离为22um的时候，像素 大小为63.3um，子像素R的发光面积为90.1um2，子像素G的发光面积为114.48um2，子像素B的发光面积为150.51um2，R、G、B的开口率分别是2.25％，2.86％，3.76％，总的开口率为8.87％，开口率较低，产品寿命较短。
上述像素排列结构，可能导致金属掩膜板的开口区域较小，因此可能导致发光的面积较小，开口率低，产品亮度不能达到要求，寿命短，使AMOLED产品良率低，在一定程度上限制了高分辨率的AMOLED面板量产。
本公开的以下实施例，提供了一种像素排列结构、有机电致发光器件、显示装置、掩模板，用以使得制造像素排列结构的金属掩膜板的开口区域较大，进而提高开口率，提高AMOLED产品亮度、寿命以及画质清晰度。
本公开实施例提供的技术方案，包括一种用于高分辨率OLED显示的Real RGB像素排列结构及其蒸镀精密金属掩膜板设计。
参见图3，本公开实施例提供的一种像素排列结构，包括多个重复排列的像素组，每一像素组包括四个像素，参见图4，其中，第一像素310和第二像素320排列在同一行，第三像素330和第四像素340排列在相邻的另一行，所述第一像素310和所述第三像素330排列在同一列，所述第二像素320和所述第四像素340排列在相邻的另一列；结合该图4所示的像素组结构，以及图3中左上角的四个像素构成的像素组，可见，所述第一像素310中的子像素的排列方式，与所述第二像素320中的子像素的排列方式不同，所述第三像素330中的子像素的排列方式与所述第二像素320中的子像素的排列方式相同，所述第四像素340中的子像素的排列方式与所述第一像素310中的子像素的排列方式相同。
也就是说，在本公开实施例提供的像素排列结构中，重复排列的像素组中，每一像素组包括四个像素，其中，第一像素和第二像素排列在同一行，第三像素和第四像素排列在相邻的另一行，所述第一像素和所述第三像素排列在同一列，所述第二像素和所述第四像素排列在相邻的另一列；所述第一像素中的子像素的排列方式，与所述第二像素中的子像素的排列方式不同，所述第三像素 中的子像素的排列方式与所述第二像素中的子像素的排列方式相同，所述第四像素中的子像素的排列方式与所述第一像素中的子像素的排列方式相同，即多个重复排列的像素组中，存在对角位置关系的两个像素中的子像素排列方式相同，而行方向上相邻的两个像素中的子像素排列方式不同、列方向上相邻的两个像素中的子像素排列方式也不同，从而实现了在行方向上或者在列方向上相邻的不同像素中的子像素的错位排列，使得制造像素排列结构的金属掩膜板的开口区域较大，提高了开口率，发光面积增大，因此提高了AMOLED产品亮度、寿命以及画质清晰度。
需要说明的是，本公开实施例中每一所述像素中包括三种颜色子像素，但本公开实施例提供的技术方案并不局限于此，每一所述像素中还可以包括四种颜色子像素等。
可选地，所述第一像素中的第一颜色子像素、第二颜色子像素、第三颜色子像素呈正三角形排列，所述第二像素中的第一颜色子像素、第二颜色子像素、第三颜色子像素呈倒三角形排列。
例如，第一颜色子像素为G子像素，第二颜色子像素为B子像素，第三颜色子像素为R子像素，参见图5，第一像素310中的R、G、B子像素的排列呈正三角形，而第二像素320中的R、G、B子像素的排列呈倒三角形。第一像素310中的R、G、B子像素的排列方式，与第四像素340中的R、G、B子像素的排列方式相同，第二像素320中的R、G、B子像素的排列方式，与第三像素中的R、G、B子像素的排列方式相同。
可选地，所述第一像素中的第一颜色子像素与所述第二像素中的第二颜色子像素、第三颜色子像素分别排列在一条直线上，所述第一像素中的第二颜色子像素、第三颜色子像素与所述第二像素中的第一颜色子像素排列在一条直线上。
例如，参见图5，第一像素310中的G子像素，与所述第二像素320中的B、R子像素排列在一条直线上，所述第一像素310中的B、R子像素，与所 述第二像素320中的G子像素排列在一条直线上，同理，第四像素340中的G子像素，与所述第三像素330中的B、R子像素排列在一条直线上，所述第四像素340中的B、R子像素，与所述第三像素330中的G子像素排列在一条直线上。
可选地，参见图6，每一所述像素中的三种颜色子像素分别为红、绿、蓝三种颜色子像素，其中，蓝色子像素311所占面积大于绿色子像素312所占面积，绿色子像素所占面积大于红色子像素313所占面积。即B子像素面积>G子像素面积>R子像素面积，图6与图5中所示的同一像素中的各子像素的相对位置相同。
可选地，参见图6，所述第一像素310与所述第三像素330在列方向上相邻的子像素颜色相同，所述第二像素320与所述第四像素340在列方向上相邻的子像素颜色相同。即第一像素310中的B子像素311与第三像素330中的B子像素331相邻，且呈轴对称分布，第一像素310中的R子像素313与第三像素330中的R子像素333相邻，且呈轴对称分布，第二像素320中的G子像素322与第四像素340中的G子像素342相邻，且呈轴对称分布。
从而使得本公开实施例中，可以采用two in one方式制作子像素，参见图7，即在列方向上相邻的同一颜色的两个子像素可以在一个开口区域中制得，提高了产品开口率，能够满足高PPI Real的RGB排列需求。
可选地，任一所述子像素与相邻的不同颜色子像素之间的距离相同，例如，参见图6，任一子像素与相邻的不同颜色子像素之间的距离均为22um，以第一像素中的G子像素为例，G子像素与同一像素中的相邻的B子像素的相对的边之间的距离为22um，该G子像素与同一像素中的R子像素的相对的边之间的距离为22um，该G子像素与第二像素中的相邻的B子像素的相对的边之间的距离也为22um，并且，同一像素中的B子像素与R子像素的相对的边之间的距离为22um。
可选地，每一所述像素中至少一个子像素为边数大于四的多边形。
可选地，每一所述子像素均为五边形。当然，也可以为六边形等。
这些五边形或六边形等边数大于四的多边形形状的子像素呈错位排列，使得发光面积变大，有效的利用了发光面积。
可选地，任意两个相邻的子像素的相对的边互相平行。
综上，本公开实施例像素排列如图6所示，每一像素中的三个不同子像素依次排列成三角形，左右相邻两个像素中的子像素的排列图形呈错位排列，第一行第一列形成的第一个像素，包含三个子像素分别为R、G和B，其中R子像素和B子像素发光面积在第一行像素中偏下的位置，G子像素发光面积在第一行像素中偏上的位置，所以组成“正三角”形状，而第一行第二列形成的第二个像素，也包含三个子像素分别为R、G和B，而其中R子像素和B子像素发光面积在第一行像素中偏上的位置，G子像素发光面积在第一行像素中偏下的位置，组成“倒三角”形状，即第一像素发光面积和第二像素发光面积分别形成一个“正三角”形状和“倒三角”形状，同理，第三像素发光面积和第四像素发光面积分别形成一个“倒三角”形状和“正三角”形状。从而两个“正三角”形状和两个“倒三角”形状形成了一个正方形形状的像素组，作为像素排列结构的基本重复单元。
本公开实施例中的R、G、B各子像素发光面积均在一行像素中，每一行像素中，包括上下两行R、G、B子像素，每一子像素为五边形，参见图7，通过这两行子像素上下错位的排列方式，提高开口率，增加发光材料的寿命；并且，两行像素中上下相邻的子像素为相同的颜色，这样相同颜色的子像素可以开一个FMM开口，也就是一个FMM开口包含两个发光区如图7所示，此种FMM设计简称two in one方式，R、G、B均为两个子像素包含在一个FMM开口中，R、G、B全部采用Two in one的方式，即每两个同一颜色的子像素通过一个开口区制得，并且这两个子像素的图形呈轴对称图形，相同像素尺寸63.3um，在PDL gap一定的情况下，例如均为22um，R像素的发光面积为266.5um2，G像素的发光面积为306.5um2，B像素的发光面积为411.5um2，R、 G、B的开口率分别是6.65％，7.65％，10.27％，总的开口率为24.57％，从而大大提高了开口率，能满足产品寿命。与传统FMM相比，本公开实施例的two in one六边形的FMM对应的子像素的开口率明显增大，如图8所示，这样明显增加了RGB发光二极管的寿命，这对于AMOLED产品是有意义的。
本公开实施例还提供的一种有机电致发光器件，包括衬底基板以及位于所述衬底基板上的所述的像素排列结构。
本公开实施例还提供的一种显示装置，包括所述的有机电致发光器件。
本公开实施例还提供的一种用于制作所述的像素排列结构的掩膜板，包括：基板，以及位于所述基板上的与所述像素排列结构中的子像素相对应的开口区域。例如，如图8所示。
可选地，每一开口区域，与在列方向上相邻且颜色相同的子像素一一对应。
可选地，每一开口区域为六边形。
本公开实施例中，每一像素组中，第一像素与第三像素在列方向上相邻的子像素颜色相同，第二像素与第四像素在列方向上相邻的子像素颜色相同，这样的排列方式有利于高精细金属掩膜板制作，即可以采用two in one方式，提高了产品开口率，能满足高PPI Real的RGB排列。上下两行两个相邻颜色相同的子像素采用同一FMM开口710，如图7所示，以红色子像素为例，采用two in one的方式，同一FMM开口710中的两个发光区域720之间的距离不受精密金属掩膜板(FMM)的限制，在PDL GAP值一定的情况下，像素开口率相比于常规设计大很多。有效的利用了面积，使发光的面积变大，不发光的面积变小，开口率大，延长寿命，同时既满足高PPI又满足Real RGB，使得产品寿命变长，满足高PPI Rear RGB排列方案，提升了产品的显示效果。
像素排列对金属掩膜板的制作起着至关重要的作用，针对本公开实施例的像素排列结构，相对于传统的slot形状的开口，开口率大大提高，相对于diamond形状的开口，本公开实施例的蒸镀金属掩膜板的RGB开口比较大，大大的降低掩膜板的制作难度，而且开口之间的距离大，能有效的防止掩膜板在 张网过程中变形从而改善蒸镀的效果，使画面更清晰。
综上所述，本公开实施例提供的技术方案，为了解决像素排列制约金属掩膜板的制作以及屏幕混色问题，提高开口率，增加AMOLED器件的寿命，本公开实施例提供一种有利于蒸镀金属掩膜板制作的真正的RGB像素排列结构。在本公开实施例提供的像素排列结构中，重复排列的像素组中，每一像素组包括四个像素，其中，第一像素和第二像素排列在同一行，第三像素和第四像素排列在相邻的另一行，所述第一像素和所述第三像素排列在同一列，所述第二像素和所述第四像素排列在相邻的另一列；所述第一像素中的子像素的排列方式，与所述第二像素中的子像素的排列方式不同，所述第三像素中的子像素的排列方式与所述第二像素中的子像素的排列方式相同，所述第四像素中的子像素的排列方式与所述第一像素中的子像素的排列方式相同，即多个重复排列的像素组中，存在对角位置关系的两个像素中的子像素排列方式相同，而行方向上相邻的两个像素中的子像素排列方式不同、列方向上相邻的两个像素中的子像素排列方式也不同，从而实现了在行方向上或者在列方向上相邻的不同像素中的子像素的错位排列，使得制造像素排列结构的金属掩膜板的开口区域较大，提高了开口率，发光面积增大，因此提高了AMOLED产品亮度、寿命以及画质清晰度。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明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。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“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。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置 关系也可能相应地改变。
