像素排布结构、显示面板及显示装置
相关申请
本申请要求2019年07月15日申请的，申请号为201910636552.4，名称为“像素排布结构、显示面板及显示装置”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及显示技术领域，特别是涉及一种像素排布结构、显示面板及显示装置。
背景技术
随着显示技术的不断发展，人们对于显示面板的分辨率的要求也越来越高。由于具有显示质量高等优点，高分辨率显示面板的应用范围也越来越广。通常，可通过减小像素的尺寸和减小像素间的间距来提高显示装置的分辨率。然而，像素的尺寸和像素间的间距的减少对制作工艺的精度要求也越来越高，从而会导致显示面板的制作工艺的难度的增加和制作成本的提高。
另一方面，子像素渲染(Sup-Pixel Rendering，SPR))技术可以利用人眼对不同颜色的子像素的分辨率的差异，改变常规的红、绿、蓝三色子像素定义一个像素的模式，通过不同像素间共享某些位置的分辨率不敏感的颜色的子像素，用相对较少的子像素数量，模拟实现相同的像素分辨率的表现能力，即提高了虚拟分辨率。但是，相关设计中，这种像素排布结构对于显示区域异形边缘区域(例如弧形区域)，不同行上的子像素沿异形边缘区域的延伸方向形成阶梯状，从而使显示面板在显示图像时，在该异形区域处图像锯齿感加重，影响显示面板的显示效果。
发明内容
基于此，有必要提供一种像素排布结构及显示面板、显示装置，以降低显示区域边缘的锯齿感，提高显示效果。
根据本申请的一个方面，提供一种像素排布结构，包括多个阵列排布的相同单元，每 一单元包括沿第一方向相邻排布的第一像素组和第二像素组，所述第一像素组和所述第二像素组均包括颜色不同的三个子像素，所述三个子像素的中心的连线形成第一虚拟三角形；
所述第二像素组的排布结构与所述第一像素组沿第二方向翻转180度后的排布结构相同；
其中，所述第一虚拟三角形的两侧边分别与所述第一方向呈第一角度α和第二角度β，且30°≤α≤60°，30°≤β≤60°；
所述第二方向与所述第一方向相互垂直。
上述的像素排布结构，每个单元中的两个像素组中的相同颜色的子像素相互错开排布，在工艺条件相同的情况下，采用这种子像素错位排布的结构，扩大了各相同子像素的开口之间可以利用的距离，可降低掩膜板制作工艺和蒸镀工艺的难度，从而可以将像素组的尺寸做的更小，有利于实现高分辨率显示屏的制造。且在第一方向和第二方向上，相邻的两个同色子像素间距较宽，有利于张网力的传输，减少了掩膜板(Mask)的变形，同样降低了精细金属掩膜板制作工艺和蒸镀工艺的难度。
此外，随着相同单元阵列排布，可以使位于显示区域异形边缘(例如弧形)的多个子像素的边缘的连线与异形边缘的切线趋于重合或平行，从而使多个子像素边缘的连线更为圆滑而接近异形边缘的形状，进而降低在异形边缘处图像的锯齿感，提高显示面板的显示效果。本申请的像素排布结构，可以使位于显示区域异形边缘的子像素包括多种颜色，从而避免显示面板的边缘处形成彩边，提高显示面板的显示效果。
根据本申请的另一个方面，提供一种像素排布结构，包括多个沿第二方向排布的子像素排，每个子像素排包括沿第一方向重复地依次排列的第一子像素、第二子像素和第三子像素；
沿所述第一方向延伸的奇数子像素排中的在第二方向延伸的同一排的子像素颜色相同；沿所述第一方向上延伸的偶数子像素排的在第二方向延伸的同一排的子像素颜色相同；相邻的两个沿所述第一方向上延伸的子像素排中相同颜色的子像素排布在所述第二方向延伸的不同排中；
沿所述第一方向延伸的同一子像素排中相邻的第一子像素和第二子像素位于相邻子 像素排中最邻近的第三子像素的沿所述第二方向延伸的中心线的两侧；
其中，沿所述第一方向延伸的同一子像素排上相邻的第一子像素和第二子像素的中心与相邻子像素排中的第三子像素的中心的连线形成第一虚拟三角形，所述第一虚拟三角形的两侧边分别与所述第一方向呈第一角度α和第二角度β，且30°≤α≤60°，30°≤β≤60°；
所述第二方向与所述第一方向相互垂直。
根据本申请的又一个方面，提供一种显示面板，包括上述实施中所述的像素排布结构。
根据本申请的再一个方面，提供一种显示装置，包括上述实施例中的所述显示面板。

具体实施方式
正如背景技术所述，目前的显示面板大多采用三色子像素作为基色来进行彩色显示，尤其是以RGB作为三基色最为普遍。有机发光二极管(organic light-emitting diode，OLED)屏体的彩色化方法有许多种，现在较为成熟并大量量产的OLED彩色化技术是OLED蒸镀技术。OLED蒸镀技术采用传统的RGB条状排布方式进行蒸镀。其中，显示画面效果最好 的是并置(side-by-side)的方式。具体的，在一个像素(Pixel)单元内有红、绿、蓝(R、G、B)三个子像素(sub-pixel)。每个子像素均呈长方形，且各自具有独立的有机发光元器件。有机发光元器件是利用蒸镀成膜技术，透过高精细金属掩膜版(Fine Metal Mask，FMM)，在array(阵列)基板上相应的像素位置形成的，其中，所述高精细金属掩膜版通常简称为蒸镀掩膜版。制作高图像分辨率即每英寸的像素(Pixels Per Inch，PPI)数量的OLED显示屏的技术重点在于精细性及机械稳定性好的FMM以及像素的排布方式。具体而言，FMM掩膜板应尽量少地发生翘曲、断裂等问题，避免造成蒸镀膜层晕开、偏移等影响蒸镀品质。像素的排布方式是决定FMM是否容易发生翘曲和断裂的主要因素。即，像素及子像素的排布方式较大程度上决定FMM的机械性能，FMM的机械性能较大程度上决定蒸镀的品质。
图1所示的相关技术中的像素排布结构通常采用图2所示的FMM进行蒸镀，该种FMM包括多个蒸镀开口B和遮挡区C，竖向方向上同一排相邻的两个蒸镀开口B之间的遮挡区称之为连接桥(bridge)。由于图1的排布方式中相同颜色的子像素是上下对位设置的，因此FMM的蒸镀开口B也必须对位设置，这使得纵向相邻的两个蒸镀开口B之间的连接桥(bridge)具有断裂的风险。并且，FMM的蒸镀开口B需要对应于预定的像素位置，按照这一种像素排布方式，FMM和子像素区的对位空间会缩小，有可能产生缺色或混色的缺陷。若增加连接桥的宽度，则子像素的尺寸将缩小，从而影响OLED显示屏的开口率，不利于高分辨率的实现。
图3为相关技术中另一种像素排布结构的排布示意图；图4为相关技术中又一种像素排布结构的排布示意图。如图3所示，所述像素排布结构包括沿竖向方向的多排子像素排，每一子像素排由子像素R、子像素G和子像素B直线排列形成，每一子像素排中的子像素B正对另一相邻的子像素排中的子像素R和子像素G。如图4所示，像素排布结构包括阵列排布的多个单元，每一单元包括由子像素R、子像素G沿竖向方向直线排布形成的第一排，以及由子像素B形成的第二排，。图3和图4的像素排布结构，虽然可以实现高分辨率，但在图3的像素排布结构中，子像素R、子像素G、子像素B排布成一排，增加了阵列走线的难度以及FMM的制作和张网难度。图4的像素排布结构中，子像素R|和子像素G排布于同一排，同样增加了阵列走线的难度，且在竖向方向上，子像素B之间的间隔不均匀，一些相邻的两个子像素B距离较近，不利于FMM张网且影响显示效果。
与此同时，相关技术中，通过在显示屏上开槽/孔(Notch)，在开槽/孔区域设置摄像头、听筒以及红外感应元件等，开槽/孔区域并不用来显示画面。该种显示屏的显示区域存在异形边缘，上述的三种像素排布结构中，在显示区域的异形边缘区域存在边缘锯齿现象。相关设计中可以通过在边缘区域加入亮度稍低的像素组，用以改变锯齿现象，在驱动芯片配置相应算法来控制亮度。然而，在配置算法的情况下，虽然可以改善边缘锯齿现象，但算法复杂度变大，增加了驱动芯片的设计难度。
为解决上述问题，本申请提供了一种像素排布结构、显示面板及显示装置，能够较佳地改善上述问题。
图5为本申请一实施例的像素排布结构的排布示意图；图6为图5所示的像素排布结构在显示区域的异形边缘区域的模拟排布示意图；图7为图5所示的像素排布结构的FMM的张网受力示意图；图8为本申请又一实施例像素排布结构的排布示意图。
参阅附图5、图6和图8，本申请一实施例的像素排布结构，包括多个阵列排布的相同的单元。每一单元包括沿第一方向01延伸且相邻排布的第一像素组1和第二像素组2，所述第一像素组1包括颜色不同的三个子像素，三个子像素的中心的连线形成第一虚拟三角形。具体地，每一像素组包括颜色不同的第一子像素12、第二子像素14和第三子像素16，三个子像素的颜色分别为红色、蓝色和绿色中的一种。在一些实施方式中，第一子像素12和第二子像素14可以排布在沿第一方向01延伸的同一排，第三子像素16可以排布在相邻的且沿第一方向01延伸的另一排，从而使三个子像素的中心连线形成第一虚拟三角形。
在其中一个实施例中，在每一单元中，第一像素组1中的第一子像素12和第二子像素14，与第二像素组2中的第三子像素16排布于沿第一方向01延伸的同一排。具体地，所述像素排布结构可以包括多个沿第一方向01延伸的子像素排。每个子像素排包括重复地依次排列的第一子像素12、第二子像素14和第三子像素16。同一子像素排中相邻的第一子像素12和第二子像素14，与相邻子像素排中的最邻近的第三子像素16形成一个像素组。这样，像素排布结构中的子像素可以排布成排，排布较为均匀，显示效果好。
每一单元中，第一像素组1沿第二方向02翻转180度后的排布结构与第二像素组2的排布结构相同。在其中一实施例中，如图5所示，每一单元包括沿第一方向01相邻排 布的第一像素组1和第二像素组2，第一像素组1沿第二方向02翻转180度后的排布结构与第二像素组2的排布结构相同，而在第二方向02上，同一排中的像素组的排布结构相同。相应地，在其中一些实施例中，像素排布结构的每一单元可以包括沿第二方向02相邻排布的第一像素组和第二像素组，第一像素组沿第一方向01翻转180度后的排布结构与第二像素组的排布结构相同，而在第一方向01上，同一排中的像素组的排布结构相同。如此，在像素排布结构中，像素组可以更紧凑的排列，从而减少像素间距，提高图像分辨率即PPI的数量。
如图5及图6所示，本申请的一实施例中，每个像素组中三个子像素的中心的连线形成第一虚拟三角形，第一虚拟三角形的两侧边分别与第一方向01呈第一角度α和第二角度β，且30°≤α≤60°，30°≤β≤60°。定义三角形的其中一边为底边，另外两条边则为侧边。本申请的实施例中，每一单元中，第一像素组1和第二像素组2沿第一方向01相邻排布，且第一像素组1沿第二方向02翻转180度后，与第二像素组2的排布结构相同。其中，第一虚拟三角形的底边为与第一方向01平行的边；第一虚拟三角形的顶点为与底边相对的点；第一虚拟三角形的侧边即为第一虚拟三角形的另外两条边。具体地，如图5和图6所示，第一像素组1和第二像素组2中子像素形成的第一虚拟三角形的底边为第一方向01平行的边，即第三子像素16的中心相对的边，第一像素组1和第二像素组2中，子像素形成的第一虚拟三角形的侧边分别为与第一方向01呈第一角度α和第二角度β的两条边。
应当理解的是，第一方向01上的每一子像素排上不同颜色的子像素重复地依次排列，每一单元中的两个像素组沿第二方向02翻转180°后的排布结构相同，且每个像素组中三个子像素的中心的连线形成的第一虚拟三角形的两个侧边与第一方向01呈第一角度α和第二角度β。如此，随着多个相同单元阵列排布，位于显示区域异形边缘W(例如弧形边缘)的多个子像素的边缘的连线与异形边缘W的切线趋于重合或平行，从而使多个子像素边缘的连线更为圆滑而接近异形边缘W的形状，进而降低在异形边缘W处图像的锯齿感，提高显示面板的显示效果。还应当理解的是，本申请实施例中的像素排布结构，可以使位于显示区域异形边缘W的子像素包括多种颜色，从而避免显示面板的边缘处形成彩边，提高显示面板的显示效果。
值得注意的是，在相同的显示区域面积和相同高PPI数量的前提下，各子像素的形状、尺寸以及像素组中的子像素的中心间距都会使虚拟三角形的两个侧边与第一方向01之间的夹角会改变。容易理解，在相同的显示区域面积和相同高PPI数量的前提下，对于本申请的实施例的像素排布结构，如将第一角度α和第二角度β保持在30°和60°的范围内，只需改变各子像素的形状、尺寸及子像素之间的间距，就可以针对不同的显示区域，有效降低显示区域异形边缘的锯齿感。相比相关设计中的像素排布结构，本申请的像素排布结构，更便于应用到不同设计的产品中，从而有效地降低设计和制作成本。
本申请的一些实施例中，属于沿第二方向02延伸的同一排上的子像素的颜色相同。如图5及图8所示，沿第二方向02延伸的同一排的像素组中相同颜色的子像素的中心位于一条直线上。在第二方向02上，相邻的两个沿第一方向01延伸的子像素排中，相同颜色的子像素错开排布，即排布在沿第二方向02延伸的不同排中；且沿第一方向01延伸的同一子像素排中，相邻的第一子像素12和第二子像素14位于相邻子像素排中最邻近的第三子像素16的沿第二方向02延伸的中心线的两侧。换言之，沿第一方向01延伸的所有奇数排中的子像素的排列方式相同，所有偶数排中的子像素的排列方式也相同，然而相邻的子像素排中，相同颜色的子像素的发光区并非上下对应，而是相互错开排列。且沿第二方向02延伸的同一排像素组的各子像素的发光区上下对应。具体地，如图5和图6所示，沿第二方向02延伸的同一排的像素组中，所有第一子像素12的中心位于一条直线上，所有第二子像素14的中心位于另一条直线上，所有第三子像素16的中心位于又一条直线上。
如此，一方面，该像素排布结构中每个像素组(pixel)由三种颜色(RGB三色)组成，可以实现真正意义上的全色显示。并且，所述像素排布结构中，沿第一方向01延伸的子像素排中，重复地依次排布有三种颜色子像素。在第二方向02上相同颜色的子像素间距较宽。相比于相关技术中，某一方向上只密布有一种颜色子像素的像素排布结构，本申请的像素排布结构，第一方向和第二方向显示较为均匀，显示效果更佳。另一方面，每个相同单元中，第一像素组和第二像素组中的颜色相同的子像素相互错开排布。在工艺条件相同的情况下，这种子像素错位排布的结构，扩大了各相同子像素的开口之间可以利用的距离，降低了掩膜版制作工艺和蒸镀工艺的难度，因而像素组的尺寸可以做得更小，有利于实现高分辨率显示屏的制造。且在第一方向01和第二方向02上，相邻的两个相同颜色的子像 素间距较宽，有利于张网力F的传输，减少了掩模板(Mask)的变形，同样降低了精细金属掩膜板制作工艺和蒸镀工艺的难度。
再一方面，第二方向02延伸的同一排的像素组中相同颜色的子像素的中心位于一条直线上，与子像素相连的阵列走线可以呈一排，便于阵列走线的布置，有利于减少阳极过孔到像素定义层的距离，降低了显示面板的制作难度，有利于高分辨率显示屏的制造。
容易理解，由于蓝色子像素B的发光效率通常是最低的，相应地所需要的发光面积就要更大，因此，一些实施例中，子像素B的面积大于红色的子像素R的面积和绿色的子像素G的面积。具体地，在一些实施方式中，第一子像素12为绿色，第二子像素14为红色，第三子像素16为蓝色，第三子像素16的开口面积大于第一子像素12的开口面积，并且大于第二子像素14的开口面积。此外，第一子像素12的开口面积可以等于第二子像素14的开口面积，使得像素排布结构具有更佳的显示效果。
需要说明的是，第一子像素12的开口面积和第二子像素14的开口面积也可以不相等，在实际应用中，可以根据需要对各子像素的开口面积进行相应地调整。
本申请的一些实施例中，多个子像素的形状相同。在一些实施例中，第一子像素12、第二子像素14和第三子像素16的形状可以为三角形、四边形或其他多边形等，在此不作限定。如此，可以保证像素排布更为均匀，且在显示区域异形边缘W的子像素边缘的连线更为圆滑，从而进一步地降低显示区域异形边缘W的锯齿感。在其中一实施例中，子像素的形状可以为菱形，如此，一方面可以使像素组中的子像素排布更为紧凑，有利于提高显示面板的开口率；另一方面，子像素的边均与第一方向01呈夹角设置，且每一子像素对应的边与前述的第一虚拟三角形的侧边更趋于平行，从而可以进一步地降低显示区域异形边缘W的锯齿感，提高显示效果。
本申请的一些实施例中，每一像素组中第三子像素16沿第二方向02延伸的中心线与第一子像素12和第二子像素14的中心连线的中垂线重合。如此，可以使第一虚拟三角形呈等腰三角形，第一子像素12、第二子像素14和第三子像素16分布均匀，显示效果较佳。在一些实施例中，对于多个沿第一方向01延伸的子像素排，相邻的奇数排和偶数排中，相同颜色的子像素(如第一子像素12)错位M个子像素排列，即，相邻两排中位置最接近的相同颜色的两个子像素的发光区中点之间的距离在第一方向01上的投影距离为M个子像 素的宽度；同一排中位置最接近的相同颜色的两个子像素的中点之间的距离为N个子像素的宽度；在子像素的形状均相同、尺寸均相等情况下，N＝2M。需要说明的是，尽管像素组中第三子像素16沿第二方向02延伸的中心线与相邻排上的第一子像素12、第二子像素14的中线连线的中垂线重合，显示效果较佳，不过，在其他一些实施例中，对于多个沿第一方向01延伸的子像素排，相邻的奇数排和偶数排即相邻两排中，相同颜色的子像素错开的尺寸可以不严格限制为M个子像素，也即相邻的第一子像素12、第二子像素14的中心的连线的中垂线与相邻排中最相邻的第三子像素16沿第二方向02延伸的中心线在第一方向01可以间隔一定距离。
本申请的一些实施例中，每一像素组中任一子像素与第一方向01上相邻的一像素组中的同颜色的子像素之间在第一方向01上的距离为第一距离，所述任一子像素与第二方向02上相邻的另一像素组中同色的子像素之间的距离为第二距离，第一距离与第二距离的比为2N/(N+1)。如图5所示，第一像素组1中的第一子像素12与第一方向01上相邻的第二像素组2中第一子像素12之间在第一方向01上的距离为X，第一像素组1中的第一子像素12与第二方向02上相邻的另一个第一像素组1中的第一子像素12之间的距离为Y，其中，N＝1，即X＝Y。在如图8所示的实施例中，N＝2，即第三像素组3中的第一子像素12与第一方向01上相邻的第四像素组4中第一子像素12之间在第一方向01上的距离为X，第三像素组3中的第一子像素12与第二方向02上相邻的另一个第三像素组3中的第一子像素12之间的距离为Y，满足Y＝4/3X。
在所述像素排布结构中，一方面，某一方向上的像素组等效为真(Real)像素排布结构中的(P+1)/P倍像素组，进而可以提高显示装置的虚拟分辨率。例如，当P＝2时，第一方向01上的2个像素组实现Real像素排布结构中3个像素组的显示效果。在一具体的产品中，第一方向01上共780个像素组可实现Real像素排布结构中1280个像素组的显示效果，进而提高显示面板的虚拟分辨率。另一方面，子像素的排布较为均匀，可以使位于显示区域异形边缘W(例如弧形)的多个子像素的边缘的连线与异形边缘W的切线趋于重合或平行，进一步地使多个子像素边缘的连线更为圆滑而接近异形边缘W的形状，从而降低在异形边缘W处图像的锯齿感，提高显示面板的显示效果。
在其中一实施例中，每一像素组中任一子像素与第一方向01上相邻的一像素组中的 同色的子像素之间在第一方向01上的距离为第一距离，所述像素组中的所述任一子像素与第二方向02上相邻的另一像素组中同色的子像素之间的距离为第二距离，第一距离与第二距离之比为1:1，即前述的N等于1。这样，不仅使子像素排布更为均匀，提高显示装置的虚拟分辨率，还进一步使位于显示区域异形边缘W(例如弧形)的多个子像素的边缘的连线与异形边缘W的切线趋于重合或平行，从而大大降低异形边缘W处图像的锯齿感。需要说明的是，一些实施例中，沿第二方向02延伸的同一排的像素组中相同颜色的子像素的中心位于一条直线上，因此，在第二方向02上相邻的两个像素组中相同颜色的子像素之间的距离即为这两个子像素的中心距离。而在第一方向01上，相邻的两个像素组中的相同颜色的子像素分别位于相邻的两个子像素排中，因此，在第一方向01上相邻的两个像素组中的相同颜色的子像素之间在第一方向01上的距离为两者的中心线之间的距离。
在上述实施例中，第一方向01是指如图5或图8所示的横向方向即水平方向，第二方向02是指如图5或图8所示的纵向方向即竖向方向。在其中一些实施例中，第一方向01为纵向方向即竖向方向，第二方向02为横向方向即水平方向，即这些实施例的像素排布结构由如图5或图8所示所述像素排布结构旋转90度或270度得到。第一方向01与第二方向02相互垂直。
可以理解的是，上述的像素排布结构还有其他适当的变形，比如旋转180度，或者第一子像素12、第二子像素14和第三子像素16的位置互调，在此不作一一例举。
图9为本申请一实施例的显示区域的异形边缘的平面示意图；图10为本申请一实施例的边缘显示单元的排布示意图。
一些实施例中，像素排布结构还包括独立于多个阵列排布的相同单元的至少一个边缘显示单元，所述边缘显示单元与阵列单元中的像素组相邻排布，且邻近显示区域的异形边缘。具体而言，显示面板具有可以界定有效显示区的轮廓线，有效显示区可以包括邻近轮廓线的边缘显示区和远离轮廓线的主显示区，前述的异形边缘显示区是指边缘显示区中轮廓线为异形的显示区。边缘显示单元包括三个颜色不同的子像素，三个子像素的中心连线形成第二虚拟三角形，第二虚拟三角形的两个侧边分别与第一方向01呈第三角度γ 1和第四角度γ 2。其中，第三角度γ 1为第二虚拟三角形中更靠近显示区域的异形边缘的一个侧 边与第一方向01形成的夹角，所述第三角度γ 1不等于第一角度α或第二角度β。具体地，如图10所示的实施例中，γ 1＜γ 2＝α＝β，即相当于将阵列单元的像素组中的第一子像素12朝向显示区域的异形边缘移动，从而形成前述的边缘显示单元，进而改变相应的夹角以适应不同的显示区域的异形边缘。在其中一个实施例中，30°≤γ 1≤60°，30°≤γ 2≤60°。
应当理解的是，在一些实施例中，显示区域的异形边缘为弧线，若弧线较为规则，即弧线的切角没有变化或变化较小，将第一角度α设置为等于第二角度β(如图6所示的实施例中)，可以有效减小异形边缘显示区的锯齿感。在另一些实施例中，弧线的切角变化较大，例如图9所示的实施例中，显示区域的异形边缘的不同位置的切角θ 1和θ 2不相等，此时，边缘显示单元中的三个子像素的中心连线形成的第二虚拟三角形的两个侧边与第一方向01形成的第三角度γ 1不等于所述第一角度α或所述第二角度β。如此，显示区域的异形边缘的不同位置的切线，与边缘显示单元中的子像素和/或邻近异形边缘的像素组中子像素的边缘的连线趋于重合或平行，从而使多个子像素边缘的连线更为圆滑而接近异形边缘的形状，进而降低在异形边缘处图像的锯齿感，提高显示面板的显示效果。
可以理解，边缘显示单元的数量可以根据实际情况而定，且至少一个边缘显示单元中的第二虚拟三角形的第三角度γ 1和第四角度γ 2的大小可以根据实际情况而定，在此不作限定。在一些实施例中，像素排布结构包括多个边缘显示单元，而多个边缘显示单元中的第二虚拟三角形的第三角度γ 1可以相同，亦可互不相同，对应的，多个边缘显示单元第四角度γ 2可以相同，或部分相同，亦可互不相同。
还可以理解的是，由于影响锯齿感主要因素是更靠近显示区域的异形边缘的子像素的排布，因此，在其中一实施例中，第二虚拟三角形的第四角度γ 2可以等于第一虚拟三角形的第一角度α和第二角度β，第二虚拟三角形的第三角度γ 1与第一角度α、第二角度β、第四角度γ 2均不相等。这样，其他子像素的显示不影响，子像素排布均匀，且显示区域的异形边缘的不同位置的切线与边缘显示单元中的子像素和/或邻近异形边缘的像素组中子像素的边缘的连线趋于重合或平行，从而降低锯齿感。
需要说明的是，本申请的实施例中，第二虚拟三角形的底边即为第二虚拟三角形的顶点相对的边，侧边即为另外两条边。其中，第二虚拟三角形的顶点为边缘显示单元中与相 邻的像素组中形成第一虚拟三角形的顶点的子像素位于不排的子像素的中心。
基于上述的像素排布结构，本申请一实施例还提供一种显示面板，该显示面板包括上述的像素排布结构。
显示面板可以为OLED发光显示面板、液晶显示面板、Micro LED、量子点显示面板等，在此不作限定。具体地，显示面板还包括与子像素一一对应连接的像素驱动电路(图未示)。在其中一个实施例中，显示面板还包括设置在边框区域的数据信号驱动电路和扫描信号驱动电路等，在此不作限定。本申请实施例中的显示面板，一个子像素可以对应连接一个像素驱动电路，在显示时可以以子像素为最小单元进行像素共用，从而实现高的像素虚拟分辨率。
基于同样的发明构思，本申请还提供一种显示装置，该显示装置包括上述实施例中的显示面板。
具体地，该显示装置可以应用于手机终端、仿生电子、电子皮肤、可穿戴设备、车载设备、物联网设备及人工智能设备等领域。例如，上述显示装置可以为手机、平板、掌上电脑、ipod、智能手表等数码设备。
