技术领域
本申请属于电子产品技术领域，尤其涉及一种像素排列结构、显示面板及显示装置。
背景技术
OLED(Organic Light Emitting Diode，有机发光二极管)相比现在的主流平板显示技术，具有高对比度、广视角、低功耗、体积更薄等诸多优点。不过由于OLED制作工艺以及现有像素排布自身特征的原因，OLED屏幕仍存在一些亟需解决的问题。
由于FMM(Fine Metal Mask，精细金属掩膜版)蒸镀工艺及像素排布结构的限制，使得显示面板中的像素密度较低，难以实现高分辨率。受到现有的像素排列结构限制，使得在显示特定文字和线条等图案时，会出现锯齿现象，或者同一像素内会存在明暗的交替变化，在OLED屏幕显示纯色画面时，可能会出现明暗相间的条纹，影响画面显示效果。
因此，亟需一种新的像素排列结构、显示面板及显示装置。
发明内容

第二方面，本申请实施例还提供了一种显示面板，包括上述实施例中的像素排列结构。
第三方面，本申请实施例还提供了一种显示装置，包括上述实施例中的显示面板。
与现有技术相比，本申请实施例所提供的像素排列结构包括第一像素单元和第二像素单元，至少两个第一子像素与至少两个第二子像素围绕至少一个第三子像素交替分布且至少两个第一子像素及至少两个第二子像素2中心点连线呈多边形，例如平行四边形，使得第三子像素贴合于第一子像素和第二子像素设置，减少各子像素之间的排布间隙，提高像素密度和分辨率。至少两个第一子像素的中心点与至少两个第二子像素的中心点的连线在行方向和列方向的至少一者上呈折线。具体是指，在行方向和/或列方向上，相邻的第一子像素和第二子像素交错设置，而不是沿同一条直线设置，使得第一子像素和第二子像素分布的更加均匀，避免在行方向和/或列方向第一子像素和第二子像素集中在同一直线上而与第三子像素之间形成明暗条纹，提高了显示面板的显示效果。

具体实施方式
为了更好地理解本申请，下面结合图1至图7根据本申请实施例的像素排列结构、显示面板及显示装置进行详细描述。
请参阅图1和图2，本申请实施例提供了一种像素排列结构，多个第一像素单元A，每个第一像素单元A包括颜色相异的至少两个第一子像素1、至少两个第二子像素2以及至少一个第三子像素3，且至少两个第一子像素1、至少两个第二子像素2和至少一个第三子像素3的个数比为2 ∶2 ∶1，至少两个第一子像素1与至少两个第二子像素2围绕至少一个第三子像素3交替分布且至少两个第一子像素1及至少两个第二子像素2中心点连线呈多边形，第二像素单元B包括第三子像素3。至少两个第一子像素1的中心点与至少两个第二子像素2的中心点的连线在行方向X和列方向Y的至少一者上呈折线；若干第二像素单元B，沿行方向X和列方向Y设置于相邻的第一像素单元A之间。
本申请实施例所提供的像素排列结构包括第一像素单元A和第二像素单元B，至少两个第一子像素1与至少两个第二子像素2围绕至少一个第三子像素3交替分布且至少两个第一子像素1及至少两个第二子像素2中心点连线呈多边形，例如平行四边形，使得第三子像素3贴合于第一子像素1和第二子像素2设置，减少各子像素之间的排布间隙，提高像素密度和分辨率。至少两个第一子像素1的中心点与至少两个第二子像素2的中心点的连线在行方向X和列方向Y的至少一者上呈折线。具体是指，在行方向X和/或列方向Y上，相邻的第一子像素1和第二子像素2交错设置，而不是沿同一条直线设置，使得第一子像素1和第二子像素2分布的更加均匀，避免在行方向X和/或列方向Y第一子像素1和第二子像素2集中在 同一直线上而与第三子像素3之间形成明暗条纹，提高了显示面板的显示效果。
需要说明的是，在本申请实施例中将像素排列结构划分为由一个第三子像素3及围绕其交替分布的两个第一子像素1和两个第二子像素2的第一像素单元A、和第二像素单元B组成。事实上，像素单元包括相邻的一个第一子像素1、一个第二子像素2和一个第三子像素3，因此第一像素单元A和第二像素单元B共同形成两个像素单元，通过第一像素单元A和第二像素单元B沿行方向X和列方向Y平移重复，实现了像素单元的均匀分布。
为了像素单元内及像素单元间第一子像素1、第二子像素2和第三子像素3的紧密排布，实现高分辨率。请参阅图1，本申请实施例中第一像素单元A内各第一子像素1及第二子像素2中心点连线呈多边形。具体的，当第一子像素1和第二子像素2的中心连线呈多边形时，第三子像素3可以更紧密的贴合该多边形的边角设置于第一像素单元A中心。同时第二像素单元B内的第三子像素3也能够更便于贴近其相邻第一像素单元A的第一子像素1和第二子像素2，从而减少各子像素之间的排布间隙，提高像素密度和分辨率。
进一步的，为避免各像素单元内第一子像素1、第二子像素2和第三子像素3分布不均，出现显著的亮度差，而在像素排列结构中出现明暗相间的现象。本申请实施例中各第一子像素1的中心点与各第二子像素2的中心点的连线在行方向X和列方向Y的至少一者上呈折线。由于相邻的第一子像素1和第二子像素2交错设置，而不是将第一子像素1和第二子像素2集中到同一直线上，使得像素单元内各子像素分布的更加均匀，避免在行方向和/或列方向第一子像素1和第二子像素2集中在同一直线上而与第三子像素3之间形成显著的亮度差，从而防止在显示纯色画面时出现明暗相间的条纹，提高了画面品质。
请参阅图1和图2，本申请实施例中至少两个第一子像素1的中心点与至少两个第二子像素2的中心点的连接在行方向X上呈折线，至少两个第一子像素1的中心点与至少两个第二子像素2的中心点的连线在列方向Y 上呈直线。使得第一像素单元A内第一子像素1和第二子像素2沿行方向X交错设置，不存在第一子像素1和第二子像素2的发光中心处于同一行的情况，即避免了第一子像素1和第二子像素2在列方向Y上与第三子像素3之间形成明暗条纹，提高了显示面板的显示效果。
在一些可选的实施例中，位于同一列的相邻两个第二像素单元B的延伸方向相平行。以提高第二像素单元B分布的规律性。
如图1所示，为了提高第二像素单元B分布的均匀性，可选的，多个第一像素单元A沿行方向X和列方向Y阵列排布，多个第二像素单元B包括在列方向Y位于相邻两行第一像素单元A之间且成行排列的多个第一类像素单元及在行方向X位于相邻两个第一像素单元A之间的多个第二类像素单元，位于同一行的相邻两个第一类像素单元的延伸方向相交。
可以理解的是，第一类像素单元和第二类像素单元分别位于相邻两行以及相邻两列的第一像素单元A之间，以便于和第一像素单元A配合，实现混光，并且在本实施例中，位于同一行的相邻两个第一类像素单元的延伸方向相交，以提高第一类像素单元的分布均匀性。可选的，第一类像素单元和第二类像素单元可以呈形状相同或者不同的矩形、平行四边形等形状，并无特殊限定。
可以理解的是，第一像素单元A内各第一子像素1及第二子像素2中心点连线可设置梯形、平行四边形等多种多边形结构，即可满足各第一子像素1的中心点与各第二子像素2的中心点的连线在行方向X和列方向Y的至少一者上呈折线即可。
为了便于说明，请参阅图1，本申请实施例中各第一子像素1及第二子像素2中心点连线呈平行四边形。具体的，第一像素单元A包括两个第一子像素1、两个第二子像素2和一个第三子像素3，两个第一子像素1的中心点组成平行四边形的一组对角的顶点，两个第二子像素2的中心点组成平行四边形的另一组对角的顶点，第三子像素3位于第一子像素1和第二子像素2所围成的区域内，即位于平行四边形的中心。通过将该多边形结构设置为平行四边形，能够有效保障各个相邻子像素之间的间隙一致且相对较小，提高了像素排布结构的开口率，相比于采用梯形的实施方式， 有效避免了因各个子像素之间的间隙不一致时所导致的亮度不均匀，产生明暗斑点或者条纹等问题。
其中，本实施例中两个第一子像素1的中心点组成平行四边形的锐角，两个第二子像素2的中心点组成平行四边形的钝角。可选的，锐角为83°，钝角为97°，平行四边形的锐角和钝角也可设置为其他度数，在此不作具体限定。
值得注意的是，请参阅图1，当第一子像素1和第二子像素2中心线连线呈平行四边形时，为实现第一子像素1的中心点与各第二子像素2的中心点的连线在行方向X上呈折线，相邻的两个平行四边形在行方向X上呈对称结构，即相邻的第一像素单元A内的第三子像素3与第二像素单元B内的第三子像素3在行方向X上呈对称结构。同时，由于第一子像素1的中心点与各第二子像素2的中心点在列方向Y上呈直线，相邻的两个平行四边形在列方向Y上结构相同，即相邻的第一像素单元A内的第三子像素3与第二像素单元B内的第三子像素3在列方向Y上结构相同。通过上述的第一像素单元A和第二像素单元B沿行方向X和列方向Y平移重复即可形成本申请实施例中的像素排列结构。
为了更便于实现将各第一子像素1及第二子像素2中心点连线形成平行四边形，本申请实施例中各第一子像素1、第二子像素2以及第三子像素3均呈多边形，此外也更便于将第一子像素1和第二子像素2围绕第3子像素3设置，减少子像素之间的排布间隙，提高像素密度。进一步的，各第一子像素1、第二子像素2以及第三子像素3均呈矩形。
在本申请一种实施例所提供的像素排列结构中，将第三子像素3设置为绿色子像素。此时为了防止出现锯齿现象，各第三子像素3的中心点连线在行方向X和列方向Y的至少一者上应呈直线，从而保证位于同一行/列的第三子像素3的发光中心位置在同一直线上，提高第三子像素3在进行横条或者竖条显示时的显示效果。
进一步的，本申请实施例中第一子像素1为红色子像素，第二子像素2为蓝色子像素，第三子像素3为绿色子像素。考虑到屏幕的寿命色偏，第二子像素2的像素开口大于第一子像素1和第三子像素3的像素开口。 具体的，由于蓝色子像素的发光衰减性强，因此当增大第二子像素2的开口时，能够提高第二子像素2处的发光寿命，保证第一子像素1、第二子像素2和第三子像素3的发光一致性，改善屏幕的寿命色偏。
在一些可选的实施例中，如图3和图4所示，至少两个第一子像素1的中心点与至少两个第二子像素2的中心点的连线在行方向X上呈直线，至少两个第一子像素1的中心点与至少两个第二子像素2的中心点的连线在列方向Y上呈折线。使得第一像素单元A内第一子像素1和第二子像素2沿列方向Y交错设置，不存在第一子像素1和第二子像素2的发光中心处于同一列的情况，即避免了第一子像素1和第二子像素2在行方向X与第三子像素3之间形成明暗条纹，提高了显示面板的显示效果。
如图3所示，可选的，在本实施中，位于同一列的相邻两个第二像素单元B的延伸方向相交，以避免第一像素单元A和第二像素单元B在列方向Y上形成明暗条纹，提高了显示面板的显示效果。
具体的，多个第一像素单元沿行方向X和列方向Y阵列排布，多个第二像素单元B包括在列方向Y位于相邻两行第一像素单元A之间且成行排列的多个第一类像素单元及在行方向X位于相邻两个第一像素单元A之间的多个第二类像素单元，多个第一类像素单元的延伸方向相平行，多个第二类像素单元的延伸方向相平行，多个第一类像素单元的延伸方向与多个第二类像素单元的延伸方向相交。
在本实施例中，通过使第二像素单元B的第一类像素单元和第二类像素单元的延伸方向相交设置，以避免第一像素单元A和第二像素单元B在行方向X以及列方向Y上形成明暗条纹，提高了显示面板的显示效果。进一步的，当第一子像素1和第二子像素2中心线连线呈平行四边形时，为实现第一子像素1的中心点与各第二子像素2的中心点的连线在列方向Y上呈折线，相邻的两个平行四边形在列方向Y上呈对称结构，即相邻的第一像素单元A内的第三子像素3与第二像素单元B内的第三子像素3在列方向Y上呈对称结构。同时，由于第一子像素1的中心点与各第二子像素2的中心点在行方向X上呈直线，相邻的两个平行四边形在行方向X上结构相同，即相邻的第一像素单元A内的第三子像素3与第二像素单元B内 的第三子像素3在行方向X上结构相同。通过上述的第一像素单元A和第二像素单元B沿行方向X和列方向Y平移重复即可形成本申请实施例中的像素排列结构。
可以理解的是，根据实际显示效果，也可以对第一子像素1、第二子像素2和第三子像素3的位置进行调整，即各第一子像素1的中心点与各第二子像素2的中心点的连线也可在列方向Y、行方向X上均呈折线。
因此，在一些可选的实施例中，如图5和图6所示，至少两个第一子像素1的中心点与至少两个第二子像素2的中心点的连线在列方向Y、行方向X上均呈折线。使得第一像素单元A内第一子像素1和第二子像素2沿行方向X和列方向Y均交错设置，不存在第一子像素1和第二子像素2的发光中心处于同一行和同一列的情况，即避免了第一子像素1和第二子像素2在行方向X和列方向Y上与第三子像素3之间形成明暗条纹，提高了显示面板的显示效果。
可选的，为了防止出现锯齿效果，每个第二像素单元B包括一个第三子像素3，第三子像素3的中心点连线在第一方向Z和垂直于第一方向Z的至少一者上应呈直线，从而保证同一斜条纹的发光中心位置在同一直线上，提高图像显示效果。
如图5所示，可选的，在本实施中，相邻两个第二像素单元B的第三子像素3的形状不同。相邻两个第二像素单元B的第三子像素3的形状与其相邻的第一子像素1和第二子像素2中心线连线的形状尺寸相匹配，具体可以为矩形、平行四边形等形状。
进一步的，当第一子像素1和第二子像素2中心线连线呈平行四边形时，为实现第一子像素1的中心点与第二子像素2的中心点的连线在行方向X和列方向Y上均呈折线，第一像素单元A内的第三子像素3和第二像素单元B内的第三子像素3的形状不同，即第三子像素3满足能贴合于各第一子像素1和第二子像素2形成的间隙内即可，其具体形状在此不作具体限定。
以上实施例仅说明了横条纹和竖条纹像素排列结构的排布方式，而当像素排列结构倾斜设置时，请参阅图7，相邻的至少两个第一子像素1的 中心点的连线在第一方向Z上呈折线，和/或相邻的至少两个第二子像素2的中心点的连线在第一方向Z上呈折线。第一方向Z和行方向X之间的夹角与第一方向Z和列方向Y之间的夹角相等。通过调整第一子像素1和第二子像素2在第一方向Z的位置，能够保证在第一子像素1、第二子像素2和第三子像素3在第一方向Z上形成过渡的位置关系，避免相邻的子像素之间存在较大的缝隙，防止纯色画面在第一方向Z出现明暗条纹。
