具体实施方式
为使本公开的原理、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
通常显示装置的分辨率由子像素的尺寸决定，故一般采用减小子像素尺寸的方式来提高显示装置的分辨率。然而，由于工艺限制，子像素尺寸的减小程度有限，因此，限制了显示装置的分辨率的提升。本公开实施例提供的子像素排列结构可以通过虚拟像素之间共用子像素的方式来提高显示装置的分辨率，弥补了制造工艺限制显示装置分辨率提升的缺陷。
示例地，图1是本公开实施例提供的一种子像素排列结构的示意图。如图1所示，该子像素排列结构可以包括：一个基准子像素阵列、多个第三子像素103 和多个第四子像素104。
其中，基准子像素阵列包括：在第一方向x和第二方向y上交替排布的第一子像素101和第二子像素102。可以看出，多个第一子像素101和多个第二子像素102可以组成基准子像素阵列，且该基准子像素阵列中的第一子像素101和第二子像素102在第一方向x和第二方向y上均交替排布。该第一方向x为基准子像素阵列中子像素的行方向，该第二方向y为基准子像素阵列中子像素的列方向，且该第一方向x与第二方向y可以相互垂直。当然，第一方向x也可以不垂直于第二方向y，本公开实施例对此不作限定。
在第一方向x和第二方向y中的至少一个方向上，基准子像素阵列中一个第一子像素101与其相邻的一个第二子像素102之间排布有一个第三子像素103；基准子像素阵列中排成两行两列的四个子像素之间排布有一个第四子像素104，该四个子像素包括两个第一子像素101和两个第二子像素102。因此，每个第四子像素104均被该基准子像素阵列中与该第四子像素104相邻的四个子像素(分别为两个第一子像素101和两个第二子像素102)包围。
需要说明的是，图1仅以在第一方向x上，基准子像素阵列中一个第一子像素101与其相邻的一个第二子像素102之间排布有一个第三子像素103的情况进行示例。可选的，图2示出了在第一方向x和第二方向y上，基准子像素阵列中一个第一子像素101与其相邻的一个第二子像素102之间排布有一个第三子像素103的情况。可选的，还可以仅在第二方向y上，基准子像素阵列中一个第一子像素101与其相邻的一个第二子像素102之间排布有一个第三子像素，本公开实施例未示出此种情况。
需要说明的是，本公开实施例中的子像素为用于显示一个像素数据的区域，例如一个有机发光二极管形成的一个发光区域，或者像素界定层的一个开口所在的区域。示例地，当该子像素为一个有机发光二极管形成的一个发光区域时，该子像素可以包括：阳极、空穴注入层、空穴传输层、发光层、电子传输层、电子注入层和阴极等结构。并且，子像素位于像素界定层的开口内。
严格意义上的像素是由完整的一个第一子像素、一个第二子像素和一个第三子像素所定义。本公开实施例中相邻的第一子像素、第二子像素、第三子像素和第四子像素均可以组成一个像素，且相邻的两个像素之间能够共用一个或多个子像素。可以看出，本公开实施例中的像素并不是严格意义上的像素，因此，以“虚拟像素”来对本公开实施例中的像素进行描述。
另外，显示装置显示的图像是由多个发光的“点”构成，通常人眼可以分辨出一个像素的中心亮度位置(也即是该“点”的中心位置)，但是无法分辨出每个像素的边界。这样一来，通过构成共用子像素的虚拟像素来显示图像，使得显示装置可以包括较多的虚拟像素，进而使得显示装置显示图像时人眼可以感知到该图像中较多的“点”，使人眼可以看到更加清晰的图像。这样也就相当于提高了包括该子像素排列结构的显示装置的分辨率。
综上所述，本公开实施例提供的子像素排列结构中，相邻的第一子像素、第二子像素、第三子像素和第四子像素均可以组成一个虚拟像素，且相邻的两个虚拟像素之间能够共用子像素，该子像素排列结构能够构成较多的虚拟像素。这样一来，人眼在观看通过该子像素排列结构展示的图像时可以感知到更清晰的图像，相当于提高了包括该子像素排列结构的显示装置的分辨率与显示效果。
可选地，第四子像素104和第一子像素101在第三方向z上交替排布，第四子像素104和第二子像素102在第三方向z上也交替排布，其中，该第三方向z与第一方向x和第二方向y均相交。比如，该第三方向z与第一方向x的夹角以及第三方向z与第二方向y的夹角均可以为45度。可选地，该第三方向z与第一方向x的夹角也可以不为45度(如40度等)，第三方向z与第二方向y的夹角也可以不为45度(如50度等)，本公开实施例对此不作限定。

在基准子像素阵列中排成两行两列的四个子像素的外切矩形区域内，第一子像素101的个数、第二子像素102的个数以及第三子像素103的个数均为第四子像素104的个数的两倍。示例地，图1中以该矩形区域内存在两个第一子像素101、两个第二子像素102、两个第三子像素103以及一个第四子像素104为例。
可选地，请参考图2，对于第一子像素101和第二子像素102中的至少一种 子像素，该子像素在第二方向y上的尺寸等于该子像素在第一方向x上的尺寸；并且，在第一方向x和第二方向y上，第三子像素103均位于相邻的第一子像素101和第二子像素102之间。
可选地，在第一方向x和第二方向y上，第三子像素103和第四子像素104均可以交替排布。可选地，在第一方向x和第二方向y上，第三子像素103的尺寸小于第四子像素104的尺寸，且第四子像素104的尺寸小于第一子像素101和第二子像素102的尺寸。
可选地，在基准子像素阵列中排成两行两列的四个子像素的外切矩形区域内，第一子像素101的个数和第二子像素102的个数均为第四子像素104的个数的两倍，第三子像素的103个数为第四子像素104的个数的四倍。示例地，图2中以该矩形区域内存在两个第一子像素101、两个第二子像素102、四个第三子像素103以及一个第四子像素104为例。
可选的，请继续参考图1或图2，基准子像素阵列中排成两行两列的四个子像素的中心可以位于矩形J的四个顶点，且基准子像素阵列中所有子像素的中心可以位于呈棋盘格排列的多个矩形J的顶点。需要说明的是，该矩形J可以为一个虚拟矩形，这四个子像素中，两个第一子像素101可以位于该矩形的一对对角顶点，两个第二子像素102可以位于该矩形的另一对对角顶点，该第四子像素104可以位于该矩形中心，图1中的第三子像素103可以位于该矩形的相对两边的中点，图2中的第三子像素103可以位于该矩形的四个边的中点。
其中，本公开实施例中的一个子像素位于顶点、中心或中点可以解释为：该子像素覆盖该顶点、中心或中点，进一步地，该子像素的中心可以与该顶点、中心或中点重合。另外，子像素的中心可以大致为子像素的几何中心，也可以是从该几何中心向子像素外辐射例如大概一定尺寸(如1/5或1/6像素尺寸)的区域。
可选的，请继续参考图1或图2，第一子像素101、第二子像素102、第三子像素103和第四子像素104的颜色可以分别为：红色、蓝色、绿色和第一颜色，该第一颜色可以与红色、蓝色以及绿色均不同，如该第一颜色可以包括白色、黄色或青色。需要说明的是，若该第一颜色为白色，则可以提高该子像素排列结构所在的显示装置的显示亮度；若该第一颜色为黄色或青色，则可以增大该子像素排列结构所在的显示装置的色域。
示例的，第一子像素101的颜色可以为蓝色，第二子像素102的颜色可以 为红色，第三子像素103的颜色可以为白色，第四子像素104的颜色可以为绿色。或者，第一子像素101的颜色可以为红色，第二子像素101的颜色可以为蓝色，第三子像素103的颜色可以为绿色，第四子像素104的颜色可以为黄色，本公开实施例对此不做限定。
可选的，上述子像素排列结构可以位于衬底上。在第一子像素101、第二子像素102、第三子像素103和第四子像素104中，颜色为蓝色的子像素在衬底上的正投影的面积可以较大。由于通常颜色为蓝色的子像素衰减较快，该子像素的寿命决定了显示装置的使用时间。本公开实施例中使颜色为蓝色的子像素在衬底上的正投影具有较大的面积，使得颜色为蓝色的子像素的寿命较长，进而可以增长显示装置的使用时间。
示例的，图1所示的子像素排列结构中第一子像素101在衬底(图1中未示出)上的正投影的面积可以与第二子像素102在衬底上的正投影的面积相等；且第一子像素101在衬底上的正投影的面积可以大于第四子像素104在衬底上的正投影的面积；第四子像素104在衬底上的正投影的面积可以大于第三子像素103在衬底上的正投影的面积。此时，第一子像素101和第二子像素102中任一子像素的颜色可以为蓝色。图2所示的子像素排列结构中，第一子像素101在衬底(图2中未示出)上的正投影的面积可以与第二子像素102在衬底上的正投影的面积以及第四子像素104在衬底上的正投影的面积均相同；第四子像素104在衬底上的正投影的面积可以大于第三子像素103在衬底上的正投影的面积。此时，第一子像素101、第二子像素102和第四子像素103中的任一子像素的颜色可以为蓝色。
可选的，子像素排列结构中的任意两个相邻的子像素的间距可以均为目标间距，且子像素排列结构中的子像素在衬底上的正投影可以均大致呈多边形。示例地，子像素的形状可以为用于界定子像素的像素界定层中开口的形状。任意两个相邻的子像素中相对的两条边的最大间距与最小间距之比的范围可以为0.8～1.2，比如，当任意两个相邻的子像素中相对的两条边的最大间距与最小间距之比为1时，这两条边相互平行。需要说明的是，由于工艺限制，通常上述多边形的边可能无法完全呈直线，故本公开实施例中的子像素满足相邻的子像素的间距大致相等，任意两个相邻的子像素中相对的两个面大致平行即可，本公开实施例对此不做限制。任意两个相邻的子像素中相对的两条边的最大间距与最小间距之比的范围也可以不为0.8～1.2，比如还可以为0.9～1.1等，本公开实 施例对此不作限定。
另外，无论子像素在衬底上的正投影是否大致呈多边形，子像素排列结构中任意两个相邻的子像素的间距与目标间距之比的范围均可以为0.8～1.2(如该比等于1，该范围也可以为其他范围，如该范围还可以为0.9～1.1等)。需要说明的是，该间距相当于用于界定子像素的像素界定层中多个开口的间距，这样一来，能够保证在制作子像素中的发光层时，用于形成发光层的开口的间距大致相等，使形成的发光层的间距大致相等，以便于高分辨率像素的制作。
可选的，本公开实施例中，子像素在衬底上的正投影可以大致呈多边形，比如，子像素在衬底上的正投影可以为多边形、具有圆角的多边形或近似圆形等。
示例的，本公开实施例中各个子像素能够紧密排列，以使得显示装置中可以具有较多的子像素。例如，图1中第一子像素101与第二子像素102在衬底上的正投影可以均大致呈八边形，第三子像素103在衬底上的正投影可以大致呈矩形，第四子像素104在衬底上的正投影可以大致呈六边形(如正六边形)。可选地，该八边形可以包括与第一方向x的夹角小于3度(或者其他度数如4度等)的两条边，以及与第二方向y的夹角小于3度(或者其他度数如4度等)的两条边；该矩形可以包括与第一方向x的夹角小于3度(或者其他度数如4度等)的两条边，以及与第二方向y的夹角小于3度(或者其他度数如4度等)的两条边；该六边形可以包括与第一方向x的夹角小于3度(或者其他度数如4度等)的两条边。比如，该八边形包括平行于第一方向x的两条边，以及平行于第二方向y的两条边；矩形包括平行于第一方向x的两条边，以及平行于第二方向y的两条边；六边形包括平行于第一方向x的两条边。
或者，图2中第一子像素101、第二子像素102和第四子像素104在衬底上的正投影可以均大致呈八边形，第三子像素103在衬底上的正投影可以大致呈矩形(如正方形)。可选地，该八边形包括与第一方向x的夹角小于3度(或者其他度数如4度)的两条边，以及与第二方向y的夹角小于3度(或者其他度数如4度)的两条边；矩形包括与第一方向x的夹角小于3度(或者其他度数如4度)的两条边，以及与第二方向y的夹角小于3度(或者其他度数如4度)的两条边。示例地，该八边形可以包括平行于第一方向x的两条边，以及平行于第二方向y的两条边；该矩形包括平行于第一方向x的两条边，以及平行于第二方向y的两条边。
需要说明的是，本公开实施例中仅以各个子像素在衬底上的正投影大致呈多边形为例，可选的，各个子像素在衬底上的正投影也可以不呈多边形，如子像素在衬底上的正投影可以大致呈圆形或椭圆形，本公开实施例对此不做限定。
本公开实施例中，相邻的第一子像素、第二子像素、第三子像素和第四子像素均可以组成一个虚拟像素。例如，图1所示的子像素排列结构中，每个第三子像素103及其周围的第一子像素101、第二子像素102与第四子像素104均可以组成一个虚拟像素。图2所示的子像素排列结构中，每相邻的第一子像素101、第二子像素102、第四子像素104及其周围的三个第三子像素103可以组成一个虚拟像素，且该虚拟像素中的三个第三子像素103可以与第一子像素101和第二子像素102均相邻。
示例的，图1中虚拟像素的结构可以参考虚拟像素A1与虚拟像素A2的结构，且虚拟像素A1与虚拟像素A2可以共用一个第四子像素104。相邻虚拟像素之间共用子像素的方式可以参考虚拟像素A1与虚拟像素A2共用子像素的方式，也即是在第二方向相邻虚拟像素之间可以共用一个第四像素104。或者，虚拟像素的结构可以参考图1中的虚拟像素A1与虚拟像素A7的结构，且虚拟像素A1与虚拟像素A7可以共用一个第二子像素102。相邻虚拟像素之间共用子像素的方式也可以参考虚拟像素A1与虚拟像素A7共用子像素的方式，也即是在第一方向相邻虚拟像素之间可以共用一个第二子像素102。
图2中虚拟像素的结构可以参考虚拟像素A3与虚拟像素A4的结构，且虚拟像素A3与虚拟像素A4可以共用两个第三子像素103和一个第四子像素104。相邻虚拟像素之间共用子像素的方式也可以参考虚拟像素A3与虚拟像素A4共用子像素的方式，也即是在第二方向相邻虚拟像素之间可以共用两个第三子像素103和一个第四子像素104。或者，虚拟像素的结构可以参考图2中的虚拟像素A3与虚拟像素A8的结构，且虚拟像素A3与虚拟像素A8可以共用一个第二子像素102和一个第三子像素103。相邻虚拟像素之间共用子像素的方式也可以参考虚拟像素A3与虚拟像素A8共用子像素的方式，也即是在第一方向相邻虚拟像素之间可以共用一个第二子像素102和一个第三子像素103。
需要说明的是，本公开实施例中的虚拟像素的结构仅以上述结构，且相邻虚拟像素之间共用子像素的方式也仅以上述方式为例。可选的，该虚拟像素可以为包括相邻的第一子像素、第二子像素、第三子像素和第四子像素的其他结构，相邻虚拟像素之间共用子像素的方式也可以为其他方式，本公开实施例对 此不做限定。如图1中的虚拟像素的结构也可以与虚拟像素A5的结构相同，或者图2中的虚拟像素的结构也可以与虚拟像素A6的结构相同。图2所示的子像素排列结构中一个虚拟像素可以包含较多的子像素。
综上所述，本公开实施例提供的子像素排列结构中，相邻的第一子像素、第二子像素、第三子像素和第四子像素均可以组成一个虚拟像素，且相邻的两个虚拟像素之间能够共用子像素，该子像素排列结构能够构成较多的虚拟像素。这样一来，人眼在观看通过该子像素排列结构展示的图像时可以感知到更清晰的图像，相当于提高了包括该子像素排列结构的显示装置的分辨率与显示效果。
本公开实施例提供了一种掩膜装置，该掩膜装置可以用于制造图1或图2所示的子像素排列结构，该掩膜装置可以包括：一个或多个掩膜板，且该掩膜板具有与第一子像素、第二子像素、第三子像素和第四子像素对应的多个开口，且每个开口用于制造其对应的子像素。
示例的，掩膜装置可以包括：与第一子像素、第二子像素、第三子像素和第四子像素一一对应的四个掩膜板。此时，上述一个或多个掩膜板包括：四个掩膜板，四个掩膜板与第一子像素、第二子像素、第三子像素和第四子像素一一对应，每个掩膜板具有与对应的子像素相对应的开口。
例如，图3至图6分别示出了用于制造图1所示的子像素排列结构的四个掩膜板。其中，图3示出了与图1所示的子像素排列结构中第一子像素101对应的掩膜板301，图4示出了与图1所示的子像素排列结构中第二子像素102对应的掩膜板302，图5示出了与图1所示的子像素排列结构中第三子像素103对应的掩膜板303，图6示出了与图1所示的子像素排列结构中第四子像素104对应的掩膜板304。当第一子像素101在衬底上的正投影大致呈八边形时，如图3所示，与第一子像素101对应的掩膜板301中可以均具有大致呈八边形的开口K11；当第二子像素102在衬底上的正投影大致呈八边形时，如图4所示，与第二子像素102对应的掩膜板302中可以均具有大致呈八边形的开口K12；当第三子像素103在衬底上的正投影大致呈矩形时，如图5所示，与第三子像素103对应的掩膜板303中具有大致呈矩形的开口K13；当第四子像素104在衬底上的正投影大致呈正六边形时，如图6所示，与第四子像素104对应的掩膜板304中具有大致呈正六边形的开口K14。
又例如，图7至图10分别示出了用于制造图2所示的子像素排列结构的四 个掩膜板。其中，图7示出了与图2所示的子像素排列结构中第一子像素101对应的掩膜板401，图8示出了与图2所示的子像素排列结构中第二子像素102对应的掩膜板402，图9示出了与图2所示的子像素排列结构中第三子像素103对应的掩膜板403，图10示出了与图2所示的子像素排列结构中第四子像素104对应的掩膜板404。当第一子像素101在衬底上的正投影大致呈八边形(如正八边形)时，如图7所示，与第一子像素101对应的掩膜板401中可以均具有大致呈八边形的开口K21；当第二子像素102在衬底上的正投影大致呈八边形(如正八边形)时，如图8所示，与第二子像素102对应的掩膜板402中可以均具有大致呈八边形的开口K22；当第三子像素103在衬底上的正投影大致呈矩形(如正方形)时，如图9所示，与第三子像素103对应的掩膜板403中可以具有大致呈正方形的开口K23；当第四子像素104在衬底上的正投影大致呈八边形(如正八边形)时，如图10所示，与第四子像素104对应的掩膜板404中可以均具有大致呈八边形的开口K24。
需要说明的是，本公开实施例仅以子像素排列结构中的子像素与掩膜板一一对应为例。可选的，子像素排列结构中不同的子像素也可以对应同一掩膜板，如图1中的第一子像素101与第二子像素102可以对应同一掩膜板，图2中的第一子像素101与第二子像素102也可以对应同一掩膜板。若先使用该掩膜板制造第一子像素101，则在使用该掩膜板制造第二子像素102时，可以调整该掩膜板的位置，以使得掩膜板上的每个开口均正对第二子像素102的形成位置。需要说明的是，若不同的子像素对应同一掩膜板，则该掩膜板的尺寸需要大于该子像素排列结构的尺寸。
可选的，掩膜装置中的掩膜板中，与颜色为蓝色的子像素对应的掩膜板中的开口的面积可以较大。假设第一子像素的颜色为蓝色，或第二子像素的颜色为蓝色，则图1所示的子像素排列结构对应的掩膜装置中，第一子像素101对应的开口K11的面积可以与第二子像素102对应的开口K12的面积大致相等，且开口K11的面积可以大于第四子像素104对应的开口K14的面积，开口K14的面积可以大于第三子像素103对应的开口K13的面积；图2所示的子像素排列结构对应的掩膜装置中，第一子像素101对应的开口K21的面积、第二子像素102对应的开口K22的面积与第四子像素104对应的开口K24的面积可以大致相等，且开口K24的面积可以大于第三子像素103对应的开口K23的面积。
需要说明的是，如图3至图10中任一所示，本公开实施例中的掩膜板中的 开口均分布均匀，在采用本公开实施例提供的掩膜板制造子像素排列结构时，可以达到较好的张网效果，不易出现掩膜板褶皱等不良，制造的子像素排列结构中各个子像素的位置精准度较高。
可选地，掩膜装置中的每个掩膜板的材质均可以为金属或非金属，本公开实施例对此不作限定。
可选的，掩膜装置还可以包括遮挡掩膜板(英文：Cover Mask)、支撑掩膜板(英文：Howling Mask)、对位掩膜板(英文：Align Mask)和组装框架，这些结构用于与上述四个掩膜板配合，以形成子像素排列结构中的子像素。
综上所述，利用本公开实施例提供的掩膜装置制造的子像素排列结构中，相邻的第一子像素、第二子像素、第三子像素和第四子像素均可以组成一个虚拟像素，且相邻的两个虚拟像素之间能够共用子像素，该子像素排列结构能够构成较多的虚拟像素。这样一来，人眼在观看通过该子像素排列结构展示的图像时可以感知到更清晰的图像，相当于提高了包括该子像素排列结构的显示装置的分辨率与显示效果。
本公开实施例还提供了一种像素排列结构的制造方法，该方法可以用于制造本公开实施例提供的像素排列结构。示例的，如图11所示，该像素排列结构的制造方法可以包括：

本公开实施例还提供了一种显示面板，该显示面板可以包括图1或图2所示的子像素排列结构。
该显示面板可以为OLED显示面板，其中每个子像素可以包括发光单元(也即有机发光二极管)，各子像素的发光单元可以直接发射所需颜色和亮度的光。
或者，该显示面板也可为液晶显示面板，其中每个子像素包括滤光单元，背光源发出的光透过各子像素的滤光单元后可以变为所需颜色和亮度的光。并且，当该显示面板为液晶显示面板时，图1或图2中的第三子像素的颜色若为白色，则可以增加像素发出的光的亮度，且可以减少背光的消耗。
在控制该显示面板显示图像时，可以先接收待显示的实际图像信息；接着根据该实际图像信息生成每个虚拟像素需展现的虚拟图像信息；之后可以采用虚拟算法确定每个虚拟像素中的子像素的显示分量，进而根据各个子像素的显示分量驱动子像素发光，以使显示面板显示图像。
可选地，该显示面板还可以包括像素界定层(如图1或图2中的白色区域所示)，该像素界定层可以具有用于界定出子像素所在区域的开口，子像素排列结构中子像素与像素界定层中的开口一一对应，每个子像素位于其对应的开口内。
本公开实施例还提供了一种显示装置，该显示装置可以包括上述显示面板。
在具体实施时，本公开实施例提供的显示装置可以为手机、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。

以上所述仅为本公开的可选实施例，并不用以限制本公开，凡在本公开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
