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，可以通过减小子像素的尺寸和减小子像素间的间距来提高显示装置的分辨率。然而，子像素的尺寸和子像素之间的间距的减小对制作工艺精度要求也越来越高，从而会导致显示装置的制作工艺的难度和制作成本增加。
子像素渲染(Sup-Pixel Rendering，SPR)技术可以利用人眼对不同色彩子像素的分辨率的差异，改变常规的红、绿、蓝三色子像素简单定义一个像素的模式，通过不同的像素间共享某些位置分辨率不敏感颜色的子像素，用相对较少的子像素，模拟实现相同的像素分辨率表现能力，从而降低制作工艺的难度和制作成本。

具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳的实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。
应当理解，尽管本文可以使用术语“第一”、“第二”等来描述各种元件，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。这些术语仅用于将一个元件和另一个元件区分开。例如，在不脱离本申请的范围的情况下，第一元件可以被称为第二元件，并且类似地，第二元件可以被称为第一元件。“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。
OLED显示面板为电流驱动，需要提供连接OLED器件的像素驱动电路，为OLED器件提供驱动电流而使得OLED器件发光。OLED器件至少包括阳极、阴极和位于阳极和阴极之间的有机发光材料。以顶发光的OLED显示面板为例，有机发光材料由于稳定性差，无法使用传统的刻蚀工艺进行图案化，取而代之的是使用利用掩膜板的蒸镀工艺进行图案化。将有机发光材料置于真空环境中，通过加热使得有机材料蒸发或者升华。蒸发有机材料的腔体和待蒸镀的阵列基板之间设置有掩模板，掩模板上设置有对应于需要蒸镀区域的开口，不需要蒸镀的区域则没有开口。蒸发或者升华的有机材料分子通过开口附着到待蒸镀的阵列基板上，从而直接形成图案化的有机材料层。对应蒸镀各个子像素发光材料层的掩模板为精细金属掩模板(FMM，Fine Metal Mask)简称精细掩模板。受制于精细掩模板开 口的尺寸、开口之间间距的尺寸限制以及张网的难度，相关技术的像素排布使得有机发光显示面板的像素密度(PPI，pixel per inch，下称像素密度)无法得到进一步的提升。
为解决上述的问题，相关技术中利用渲染像素技术(SPR，Sub Pixel Rendering)来提升显示面板的分辨率。如图1所示，采用非渲染的像素包括三个子像素，而采用渲染的像素仅包括2个子像素，因此可以在子像素不变的情况下像素的个数提升了50％，进而提升了分辨率。然而渲染像素技术中每个像素仅包括2个子像素，其为了实现全彩色显示需要向旁边的子像素借用其不能显示的颜色。因此，该类像素排布结构进行显示时，由于在行方向和/或列方向上各个颜色的子像素的数量有差异，或显示边缘的子像素的凸出程度不同，会导致在画面边缘出现彩边，影响显示质量。
与此同时，为使显示面板具有较好的发光效果，子像素的排布期望更均匀，且将相邻的同色子像素设计为共用一个掩膜板开口，从而增加掩膜板的开口面积，降低对位难度。但是，采用该种像素排布结构的显示面板在显示时会出现人眼难以将相邻的同色子像素清晰分辨，导致视觉上合二为一的情况发生而产生颗粒感，影响显示质量。
此外，为使终端设备实现更多的功能，屏下显示区域设置感光器件也越来越广泛，例如，在屏下显示区域设置指纹识别器件。其中，指纹识别器件包括用于指纹图像获取的感光器件，该感光器件可以包括光学传感器，光学传感器可以包括多个像素点，该多个像素点可以分别接收物体不同位置反射的光信号，并将接收的光信号转换成电信号，从而生成物体的图像。因此，像素点接收的光信号的进光量以及对比度均会影响所生成的物体的图像质量。如此，对显示面板的透光性也具有一定的要求，进一地为像素排布结构的设计增加了难度。
为解决上述问题，本申请实施例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。

参阅附图，本申请至少一实施例中的显示面板100，包括显示区域10和非显示区域20，显示区域10通过多个子像素来显示图像。具体地，显示区域10可以为矩形，非显示区域20环绕显示区域10设置，当然，显示区域10和非显示区域20的形状和布置包括但不限于上述的示例，例如，当显示面板100用于佩戴在用户上的可穿戴设备(例如手表)时，显示区域10可以具有圆形形状；当显示基板用于车辆上进行显示时，显示区域10及非显示区域20可采用例如圆形、多边形或其他形状。显示区域10设有发射不同颜色光的多个子像素，子像素意味着用于发射光的最小单元(例如，显示面板100的最小可寻址单元)。

具体参见图3至图7，本申请的第一方面提供了一种像素排布结构。
根据本申请的第一方面，本申请公开的至少一实施例中的像素排布结构，包括多个第一像素单元和多个第二像素单元。第一像素单元和第二像素单元彼此相邻，且多个第一像素单元与多个第二像素单元在第一方向以及第二方向上交替排布。例如，如图5及图6所示，第一方向为图中的X方向，第二方向为图中的Y方向。在第一方向上，第一像素单元和第二像素单元交替排布，在第二方向上，第一像素单元和第二像素单元交替排布。也就是说，在第一方向和第二方向上，任意两个相邻的第一像素单元由一个第二像素单元间隔开来，任意两个相邻的第二像素单元由一个第一像素单元间隔开来。作为一种具体地实施方式，第一方向与行方向的夹角为45°，第二方向与第一方向相垂直，与列方向的夹角 为45°。如此，使子像素可以紧凑排布，充分利用空间，提高了开口率。
第一像素单元和第二像素单元均包括第一子像素12、第二子像素14、第三子像素16a和第四子像素16b。第一子像素12、第二子像素14、第三子像素16a和第四子像素16b可以分别为红色的子像素、蓝色的子像素和绿色的子像素中的一种。当然，在其他一些实施例中，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b还可以为发射红色、绿色和蓝色之外其他颜色光的子像素，例如，白色或黄色，在此不作限定。应当理解的是，不同颜色光具有不同的波长，波长越高意味着光的能量越高，能量高的光容易引起有机发光材料的衰变，使得发射能量高的光子的子像素更容易衰减。蓝光波长相较于红光波长和绿光波长短，因此，蓝光的能量更高，发射蓝光的有机发光材料更容易发生衰变，导致像素单元中发出的光容易偏红，造成白光色偏现象。且，每个子像素发射的光通过微腔效应在阳极和阴极之间重复反射和再反射，进行放大和相长干涉，光的亮度增加，色偏情况进一步被放大。作为一种较佳地实施方式，蓝色的子像素的发光面积大于红色的子像素和绿色的子像素的发光面积，这样，可以一定程度降低因发射不同颜色光的有机发光材料衰减速率不同而造成的显示不良。例如，具体到如图3及图4所示的实施例中，第一子像素12为蓝色的子像素，第二子像素14为红色的子像素，第三子像素16a和第四子像素16b为绿色的子像素。则第一子像素12的发光面积大于第二子像素14的发光面积，第二子像素14的发光面积大于第三子像素16a或第四子像素16b的发光面积。需要指出，一些实施方式中，绿色的子像素的发光面积可以与红色的子像素的发光面积相等，但由于人眼对绿光比较敏感，在另一些实施方式中，绿色的子像素的发光面积可以小于红色子像素的发光面积，在此不作限定。
在一个像素单元内，具有以第一子像素12、第二子像素14、第三子像素16a和第四子像素16b的各自中心为顶点构成共边但不交叠的共边三角形。具体地，如图3和图4所示，第一子像素12位于第三子像素16a的中心和第四子像素16b的中心之间的中心连线c的一侧，第二子像素14位于第三子像素16a的中心和第四子像素16b的中心之间的中心连线c的另一侧。第一子像素12、第二子像素14、第三子像素16a和第四子像素16b的中心依次连线形成虚拟四边形，第二子像素14、第一子像素12和第三子像素16a的中心连线构成第一三角形(图未标)，第二子像素14、第一子像素12和第四子像素16b的中心连线构成第二三角形。第一三角形和第二三角形以第一子像素的中心和第二子像素的中心之间的中心连线d作为共同边，且两个三角形彼此不交叠。作为一种较佳的实施例中，共边三角形为锐角三角形，如此，使像素结构的子像素排布较为均匀，有利于提高显示效果。其中，第二像素单元中各子像素结构旋转预定角度后与所述第一像素单元中各子像素结构成镜像对称。也就是说，第一像素单元中的子像素和第二像素单元中的同色子像素的形状、大小(发光面积)相同，第二像素单元沿顺时针或逆时针旋转预定角度后的子像素结构与第一像素单元中对应的子像素的结构镜像对称。其中，所述预定角度大于0°，小于360°，例如，图4所示的第二像素单元的子像素排布结构顺时针旋转90°后沿第一方向与图3所示的第一像素单元的子像素排布结构成镜像对称。
可以理解，像素排布结构直接决定着显示效果，为保证显示均匀，如图1所示，各子像素通常会沿着行方向和列方向呈一定规则尽可能均匀排布，但该种像素排布结构容易出现色偏、彩边和视觉颗粒感。采用本申请实施例公开的像素排布结构，第二像素单元的子像素排布结构旋转预定角度后与第一像素单元的子像素排布结构成镜像对称。如此，可以兼顾子像素的排列紧密度和子像素之间的间距，在二者之间寻求一个平衡，有利于降低混色风险和色偏、改善彩边，和视觉颗粒感。例如，可以将第三子像素16a和第四子像素16b设置为人眼敏感颜色的子像素，如绿色的子像素，每一个绿色的子像素均可由红色的子像素和蓝色的子像素围绕，有效的改善了色偏。又例如，第一像素单元和第二像素单元重复排列形成显示矩阵时，第二像素单元中各子像素结构旋转预定角度后与第一像素单元 中各子像素结构成镜像对称，使在行方向或列方向避免发射同种颜色光的子像素单独排成一列，有效改善了显示边缘的彩边问题。此外，采用前述的像素排布结构，可以适当拉大同一像素单元中的同色子像素的距离，如将人眼敏感的第三子像素16a和第四子像素16b的距离适当拉大，而将第一子像素12和第二子像素14设置为彼此靠拢，不仅可以避免显示时人眼敏感子像素无法分辨而识别为一个造成的显示颗粒感，还可以尽可能使相邻的像素单元之间能够形成面积较大的透光预留区Z(见图5)，有利于提高屏下感光器件的采光面积。
一些实施例中，同一像素单元中，第二子像素14的中心和第一子像素12的中心之间的中心连线d，和第三子像素16a的中心和第四子像素16b的中心之间的中心连线c的长度不等。容易理解，通常发射不同颜色光的子像素的发光面积大小不同，例如，蓝色的子像素的发光面积大于红色的子像素和绿色的子像素的发光面积大小。通过将中心连线d的长度设计为与中心连线c的长度不等，可以保证第二子像素14和第一子像素12之间的间距，以及第三子像素16a和第四子像素16b的间距满足预设条件，以尽可能使各子像素紧密排列，且改善敏感颜色子像素的分布均匀性，提高视觉上的分辨率，提升显示质量。
一些实施例中，第一像素单元中第二子像素14的中心与第三子像素16a的中心之间的中心连线a的长度，不等于第一像素单元中第二子像素14的中心与第四子像素16b的中心之间的中心连线b的长度。第二像素单元中第二子像素14的中心与第三子像素16a的中心之间的中心连线的长度，不等于第二像素单元中第二子像素14的中心与第四子像素16b的中心之间的中心连线的长度。具体到实施方式中，第二子像素14为红色的子像素、第一子像素12为蓝色的子像素，第三子像素16a和第四子像素16b为绿色的子像素。同一像素单元中红色子像素与不同的绿色子像素的中心连线长度不同。如此，加剧了子像素的错位排布，在第一像素单元和第二像素单元重复排列形成显示矩阵时，进一步地避免同色子像素单独排成一列，且弱化了同一行或列的子像素的凸出程度，从而改善了显示边缘的彩边问题。
需要说明的是，子像素的中心可以是子像素图形的几何中心，也可以是子像素的发光颜色的中心，在此不作限定。
一些实施例中，同一像素单元中，沿第一方向和第二方向，相邻的两个子像素之间的最小距离为n，沿第一方向和第二方向，相邻的两个像素单元中最相邻的不同颜色的子像素之间的最小距离也为n。其中，10um<n<30um。如此，一方面，使子像素的排布更为均匀，有利于提高显示质量，另一方面，可以有效的避免相邻子像素之间的发光串色或干扰产生锯齿感。
进一步地，如图5所示，第一像素单元中的第二子像素R1与沿第二方向相邻排布的第二像素单元的第三子像素G21之间的最小距离为p，n<p<3n。第二像素单元中的第二子像素R2与沿第一方向相邻排布的第一像素单元的第三子像素G11的最小距离为q，n<q<3n。如此，可以界定出了透光预留区Z拥有足够大小，进而满足屏下感光器件的正常工作所需要的进光量。
需要说明的是，本申请实施例提供的显示面板，可以为有机发光显示面板，子像素至少包括阳极和阴极，以及位于阳极和阴极之间的发光层，驱动电路向阳极和阴极之间施加电压，激发载流子迁移，作用于发光层，从而发射出光线。显示面板还可以包括像素定义层，像素定义层界定出了多个像素开口，子像素的发光层设于像素开口中，以避免相邻的子像素之间发生串色或干扰。因此，像素开口的面积即为子像素的发光面积。但是，受限于蒸镀技术，为保证发光材料完全蒸镀于像素开口内，通常，掩膜板的开口面积大于像素开口的面积，以留有蒸镀余量。例如，如图3所示，子像素的内侧边称为像素边，即是像素定义层(Pixel Define Layer，PDL)的像素开口的边界，外侧边称为子像素的虚拟边，所述虚拟边是指Mask(掩膜板)的蒸镀开口的边界。故，本申请的实施例中，子像素之间的 间距是指两个子像素的像素边之间的距离。较佳地，各子像素的每一像素边与对应的虚拟边彼此平行，并且各像素边距对应的虚拟边的垂直距离相等。这样使得最终的子像素排列更为均匀和规则，从而可以有效提高子像素的发光层的制作精度和良率，并降低Mask张网时产生褶皱风险。
示例地，第一子像素、第二子像素、第三子像素和第四子像素可以为具有长轴和短轴的规则图形或不规则图形，例如，椭圆形、圆形、扇形、哑铃形、梨形、四边形、矩形、类矩形、圆角矩形、星形、心形的一种。如图5及图6所示，作为一种较佳的实施方式，第一子像素、第二子像素、第三子像素和第四子像素均可以为矩形或类矩形。第一子像素、第二子像素、第三子像素和第四子像素的长轴方向(延伸方向)与行方向和列方向相交。这样，一方面，相较于其他子像素形状，子像素之间排列可以做到紧密排布，且避免同色子像素独立成一行，有效改善彩边现象。另一方面，使位于显示面板异形边缘的子像素更能匹配圆角设计，即子像素的倾斜与圆角的弧度相切或相吻合，实现各子像素边缘在圆角处的平滑过渡，进而改善圆角处的锯齿问题。较佳地，第一子像素、第二子像素、第三子像素和第四子像素的延伸方向与第一方向相平行，行方向和列方向相互垂直，并且该第一方向与行方向或列方向的夹角为30°-60°。这样，可以进一步使子像素的倾斜与圆角的弧度相切或相吻合，实现各子像素边缘在圆角处的平滑过渡，进一步改善圆角处的锯齿问题。需要强调的是，由于人眼对水平或垂直方向上的画面质量较为敏感，而对与水平方向的夹角为45°的方向上的画面质量较为不敏感，因此，作为一种优选的实施方式，如图6所示，第一方向与行方向的夹角为45°，如此可以进一步提高整体显示质量。特别指出的是，掩膜板受力通常沿行或列方向传递，例如，掩模板的张网力F沿行方向传递，对应子像素相对行或列方向倾斜设置的掩膜板的开口可以将受力在行方向和列方向分解，从而避免FMM的张网力F集中造成的开口变形，降低了掩膜板的制作难度和张网难度。且掩膜板的开口倾斜设置，在同样长度和宽度的掩膜板中，可以设置更多的开口，降低了掩膜的制作成本。
具体到一个实施例中，第一子像素可以为正方形或类正方形，第二子像素的形状为矩形或类矩形，第三子像素和第四子像素为矩形或类矩形。如此，在使子像素紧密排列的同时，可以让各子像素错位排布，从而有效改善了彩边。需要说明的是，类矩形或类正方形是指，由于工艺限制或者为了掩膜板的制作便利，子像素的形状可能不是严格的矩形或正方形，而是大致为矩形或正方形，例如，具有圆角的圆角矩形或切角矩形。其中，圆角矩形是矩形的顶角被倒圆角形成的形状，切角矩形是矩形的顶角被切掉一个或多个所形成的形状。将子像素的形状设置为类矩形或类正方形可以更加灵活地调整子像素的开口率，并满足掩膜板在制作时的限制条件。
一些实施例中，第三子像素和第四子像素的发光面积相同。例如，第三子像素和第四子像素可以设置为人眼敏感颜色的子像素，这样，可以尽可能提高分辨率的同时，使显示更为均匀。进一步地，第二子像素、第三子像素和第四子像素的发光面积也可以相同。如此，有利于子像素排布整体上更为紧凑和均匀，提高了显示效果。具体到一些实施例中，第一子像素具有第一长轴和第一短轴；第二子像素具有第二长轴和第二短轴；第三子像素具有第三长轴和第三短轴，第四子像素具有第四长轴和第四短轴。也就是说，各子像素均为具有长轴和短轴的规则图形或不规则图形，例如前述的矩形或类矩形。其中，第三子像素和第四子像素为同色子像素，例如均为绿色的子像素，则第三长轴和第四长轴彼此平行且长度相等，第三短轴和第四短轴彼此平行且长度相等，这样，使第三子像素和第四子像素的发光面积相等。
一些实施例中，第一长轴和第一短轴的长度的比值在1.5～1之间；第二长轴和第二短轴的长度的比值在5～1之间；第三长轴和第三短轴的长度的比值在5～1之间。例如，如图3及图4所示的实施例中，第一子像素为正方形，第二长轴和第二短轴之比为1，第二子 像素、第三子像素和第四子像素均为长方形，第二子像素、第三子像素和第四子像素的长短轴之比在5：1之间。如此，可以尽可能保证开口率的前提下，相应的使各子像素能够错位排布，以尽可能降低彩边现象。且还可以尽可能使相邻的子像素之间能够形成面积较大的透光预留区，有利于提高屏下感光器件的采光面积。
需要说明的是，子像素的长轴的长度是指子像素的发光区纵长延伸方向的最大尺寸，子像素的短轴的长度是指子像素的发光区在与发光区纵长延伸方向相对的宽度方向的最大尺寸。
一些实施例中，第二子像素14的长边与第一子像素12的一组相对边、第三子像素16a的长边以及第四子像素16b的长边相互平行。可以理解，第一子像素为正方形或类正方形，因此其彼此相对的一组对边彼此平行且长度相等，而第三子像素和第四子像素为矩形或类矩形，则其具有一组彼此平行的长边和一组彼此平行的短边。例如，如图3所示，第一子像素12具有分别与第三子像素16a和第四子像素16b彼此相对的第一边和第二边、与第一边相邻且与第二边相对的第三边，以及与第一边相对且与第二边和第三边相邻的第四边。其中，第一子像素12的第一边和第四边与第二子像素14的长边彼此平行，且与第三子像素16a和第四子像素16b的长边彼此平行。如此，有利于子像素均匀排布，进而提高了显示质量。
一些实施例中，在第一像素单元内，第一子像素12靠近第一像素单元边缘的一条边的延长线与第三子像素16a靠近第一像素单元同侧边缘的一条短边的延长线重合。第一子像素12靠近第一像素单元边缘的另一条边的延长线与第四子像素16b靠近第一像素单元同侧边缘的一条长边的延长线重合。具体到实施例中，一个像素单元，第一子像素12的第三边可以与第三子像素16a的短边共线，第一子像素12的第四边可以与第四子像素的长边共线。如此，尽可能地保证像素单元呈规则形状，使子像素排布更紧凑和均匀。
一些实施例中，如图3及图4所示，第一子像素12的第二边的延长线与第三子像素16a不重合，第一边的延长线与第四子像素16b不重合。如此，保证了子像素之间的错位排布，弱化了显示边缘的子像素的凸出程度，有效改善了显示边缘的彩边问题。
一些实施例中，第二子像素、第三子像素和第四子像素的长边长度与第一子像素的边长可以相同。如此，进一步的使第一像素单元呈规则形状，使子像素排布更紧凑和均匀。
一些实施例中，在第一像素单元中，第二子像素14的两条长边中的至少一条长边的延长线穿过第一子像素12与第三子像素16a之间的间隙。进一步地，第二子像素14的一条长边的延长线穿过第一子像素12与第三子像素16a之间的间隙，第二子像素14的另一条长边的延长线与第一子像素12的靠近第三子像素16a的边重合。例如，如图3所示，第二子像素14的一条长边的延长线穿过第一子像素12和第三子像素16a之间。第二子像素14的另一条长边的延长线与第一子像素的第一边共线。在第二像素单元中，第二子像素14的两条长边中的至少一条长边的延长线穿过第一子像素12与第四子像素16b之间的间隙。进一步地，第二子像素14的一条长边的延长线穿过第一子像素12与第四子像素16b之间的间隙，第二子像素14的另一条长边的延长线与第一子像素12的靠近第四子像素16b的边重合。例如，如图4所示，第二子像素14的一条长边的延长线穿过第一子像素12和第四子像素16b之间。第二子像素14的另一条长边的延长线与第一子像素的第一边共线。如此，使子像素排布均匀的前提下，尽可能保证透光预留区的大小，有利于例如屏下摄像功能的实现。当然，另一些实施例中，在第一像素单元中，第二子像素14的两条长边的延长线均穿过第一子像素12与第三子像素16a之间的间隙。也就是说，将第二子像素14沿第一方向的反方向平移能够穿过第一子像素12和第三子像素16a之间。在第二像素单元中，第二子像素14的两条长边的延长线均穿过第一子像素12与第四子像素16b之间的间隙。也就是说，将第二子像素14沿第二方向的反方向平移能够穿过第一子像素12和第四子像素16b之间。
参阅图5及图6，本申请的一些实施例中，相互相邻的两个第一像素单元和两个第二像素单元构成重复单元(如图6的虚线方框所示)；多个重复单元沿第一方向X和第二方向Y排布；每个重复单元包括两个第一像素单元和两个第二像素单元，两个第二像素单元分别位于两个第一像素单元几何中心连线的一侧。例如，如图5及图6所示，多个重复单元沿第一方向和第二方向阵列排布形成显示矩阵。可以理解，随着刘海屏或者显示屏开孔的技术的应用，显示区域异形边缘区域(例如弧形区域)锯齿感也是影响显示质量的一个因素。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。因此，作为一种实施例方式，多个重复单元可以沿与行方向和列方向相交的第一方向(X方向)和第二方向(Y方向)排布，随着重复单元重复排布，可以使位于显示区域异形边缘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，进而能够降低在异形边缘处图像的锯齿感，有利于提高显示面板的显示效果。此外，还可以使位于显示区域异形边缘的子像素包括多种颜色，从而进一步降低显示面板的异形边缘处形成的彩边的情况，进而提高显示面板的显示效果。
一些实施例中，如图5及图6所示，在一个重复单元中，任一第二像素单元和在第一方向X与其相邻的第一像素单元中，第二像素单元内的第二子像素R2的中心点与第三子像素G21的中心点的连线长度为L1，第一像素单元内的第二子像素R1的中心点与第二像素单元内的第三子像素G21的中心点的连线长度为L2，L1不等于L2。该第二像素单元和在第二方向Y与其相邻的另一个第一像素单元中，第二像素单元内的第二子像素R2的中心点与另一个第一像素单元内的第四子像素G12的中心点的连线长度为L3，另一个第一像素单元内，第二子像素R1的中心点与第四子像素G12的中心点的连线长度为L4，L3不等于L4。也就是说，同一重复单元中，两个相邻像素单元里多个红色子像素的中心和多个绿色子像素的中心之间的中心连线的长短不同。如此，保证各子像素的错位排布，在第一像素单元和第二像素单元重复排列形成显示矩阵时，进一步地避免同色子像素单独排成一列，且弱化了同一行或列的子像素的凸出程度，从而改善了显示边缘的彩边问题。
一些实施例中，如图6所示，在一个所述重复单元中，任一所述第二像素单元和在第一方向X与其相邻的第一像素单元中，所述第二像素单元内的所述第二子像素R2、所述第三子像素G21，以及所述第一像素单元内的所述第二子像素R1的中心点之间的连线构成不等边三角形S1。且该所述第二像素单元和在第二方向Y与其相邻的另一个第一像素单元中，所述另一个第一像素单元中的所述第二子像素R1、第四子像素G12以及该所述第二像素单元内的所述第二子像素R2的中心点之间的连线构成不等边三角形S2。也就是说，同一重复单元中，一个第二像素单元内的红色子像素，和在行方向和列方向与所述第二像素单元相邻第一像素单元中的红色子像素和不同的绿色子像素的中心之间的连线分别可构成不等边三角形。如此，在第一像素单元和第二像素单元重复排列形成显示矩阵时，也可以进一步避免同色子像素单独排成一列，且弱化了同一行或列的子像素的凸出程度，从而改善了显示边缘的彩边问题。
一些实施例中，在一个重复单元中，任意两个第二子像素中心连线与任意一个第二子像素的中心和第三子像素的中心之间的中心连线非重合，任意两个第二子像素的中心之间的中心连线与任意一个第二子像素中心和第四子像素的中心连线非重合。例如，一些实施例中，第二子像素为红色的子像素，第一子像素为蓝色的子像素，第三子像素和第四子像素为绿色的子像素。任意两个红色子像素之间的连线，例如相邻像素单元中的第二子像素R1和R2之间的中心连线，与R1/R2和G11/G12/G21/G22任意两者之间的中心连线不共线。例如，如图6所示，第二子像素R1和R2之间的中心连线LL1与第二子像素R1和相邻像素单元的第四子像素G21之间的中心连线LL2不重合。换言之，同一重复单元中沿第一方向相邻的第一像素单元和第二像素单元中的两个红色的子像素R1和R2的中心连 线，穿过所述相邻的第一像素单元和第二像素单元中位于同一像素单元的蓝色子像素B2和G21之间。同理，沿第二方向相邻的第一像素单元和第二像素单元中的两个红色的子像素R1和R2的中心连线，穿过所述相邻的第一像素单元和第二像素单元中位于同一像素单元的蓝色子像素B1和G11之间。如此，不仅可以使像素排布结构整体上避免发射同种颜色光的子像素单独排成一列，进一步弱化了显示边缘的子像素的凸出程度，有效改善了显示边缘的彩边问题。
一些实施例中，如图6所示，在一个重复单元中，每个第一像素单元中穿过第一子像素中心与第三子像素中心的第一虚拟连接线相互平行；每个第二像素单元中穿过第一子像素中心与第四子像素中心的第二虚拟连接线相互平行；第一虚拟连接线与第二虚拟连接线非重合。具体到实施例中，如图5及图6所示，同一重复单元中B1与G11的中心之间的连线相互平行，即LL3与LL4相互平行，B2和G22的中心之间的连线相互平行，即LL5与LL6相互平行。且同一重复单元中，两个相同子像素结构的像素单元中的蓝色子像素和绿色子像素的中线连线的延长线不共线。如此，可以使像素排布结构整体上避免发射同种颜色光的子像素单独排成一列，弱化了显示边缘的子像素的凸出程度，有效改善了显示边缘的彩边问题。
一些实施例中，如图6所示，在一个重复单元中，一个第一像素单元中的第一子像素与第二子像素中心连线和另一个第一像素单元中的第一子像素与第二子像素中心的连线的延长线非重合，即LL7和LL8非重合。一个第二像素单元中的第一子像素与第二子像素中心之间的连线与另一个第二像素单元中的第一子像素与第二子像素中心之间的连线的延长线非重合。任一个第一像素单元中的第一子像素与第二子像素中心之间的连线与任一个第二像素单元中的第一子像素与第二子像素中心之间的连线的延长线非重合。也即是说，如图5及图6所示，同一重复单元中，不同像素单元中红色的子像素和蓝色的子像素的中心之间的连线的延长线均不共线。例如，两个第一像素单元中的红色的子像素R1的中心和蓝色的子像素B1的中心之间的两条中心连线、两个第二像素单元中的红色子像素R2的中心和蓝色的子像素B2的中心之间的两条中心连线均不共线。可以理解，由于第一子像素和第二子像素位于第三子像素的中心和第四子像素的中心之间的连线的两侧，将同一重复单元中的不同像素单元的红色子像素和蓝色子像素的中心之间的连线设置为不共线，则使同一列的子像素包括多种颜色，有效改善了显示边缘的彩边问题。
一些实施例中，在一个重复单元中，每个第一像素单元中穿过第二子像素中心与第三子像素中心的第三虚拟连接线相互平行；每个第二像素单元中穿过第二子像素中心与第四子像素中心的第四虚拟连接线相互平行；所述第三虚拟连接线与所述第四虚拟连接线非重合。具体到实施例中，如图5及图6所示，同一重复单元中，两个相同子像素结构的像素单元中的红色子像素的中心和绿色子像素的中心之间的连线的延长线不共线。如此，可以使像素排布结构整体上避免发射同种颜色光的子像素单独排成一列，弱化了显示边缘的子像素的凸出程度，有效改善了显示边缘的彩边问题。
值得强调的是，屏下感光器件接收的光信号的进光量以及对比度均会影响所生成的物体的图像质量，采用其他像素排布结构的显示面板，虽然可透光区域较多，使总体的透光面积无差异，但在特定区域内连续的透光区域的面积较小，无法满足屏下感光器件正常工作所需的光透过率。本申请的一些实施例中，在第一方向X上相邻的第一像素单元和第二像素单元中，第一像素单元内的第二子像素R1与该第二像素单元内的第四子像素G21之间的距离大于该第一像素单元内的第三子像素G11和第四子像素G12与该第一子像素R1之间的距离，如图5所示，例如，L5大于L6，且L5大于L7。如此，每一重复单元中可以形成连续的透光预留区Z，从而提高了显示面板的透光率，为显示面板的功能多样化提供了便利性。作为一种实施方式，透光预留区Z的面积大于一个第二子像素R1/R2的发光面积。
可以理解，每个重复单元包括两个第一像素单元、两个第二像素单元以及由相邻的子像素之间间隔形成的透光预留区。较佳地，每个重复单元位于一个虚拟正方形内，重复单元阵列排布时，多个虚拟正方形以共享边的形式阵列排布形成显示矩阵。如此，有利于显示均匀性，提高了显示效果。
一些实施例中，如图7所示，该像素排布结构包括由四个虚拟四边形以共享边的方式排布形成的虚拟多边形，所述四个虚拟四边形具体包括第一虚拟四边形30、第二虚拟四边形40、第三虚拟四边形50和第四虚拟四边形60。第一虚拟四边形30沿行方向与第三虚拟四边形50共享第一共享边g，在列方向与第二虚拟四边形40共享第二共享边h。第四虚拟四边形60沿列方向与第三虚拟四边形50共享第三共享边j，在行方向与第二虚拟四边形40共享第四共享边i。第一虚拟四边形30、第二虚拟四边形40、第三虚拟四边形50和第四虚拟四边形60远离共享边的侧边构成了虚拟多边形的各个边。第一子像素位于各虚拟四边形的第一顶点位置处，第二子像素位于各虚拟四边形的第二顶点位置处，第一顶点和第二顶点交替且间隔设置，绿色的子像素位于各虚拟四边形内。
进一步地，每一前述的虚拟四边形的任一边与行或列方向不平行；或者每一前述的虚拟四边形的任意两条边的长度不相等；或者每一前述的虚拟四边形的任意两条边彼此不平行；或者每一前述的虚拟四边形的任意两个内角不相等。如此，第一虚拟四边形、第二虚拟四边形、第三虚拟四边形和第四虚拟四边形均为不规则的四边形，从而可以在满足子像素排布紧凑的前提下，形成较大的透光区域，从而进一步提高了显示面板的透光率，为显示面板的功能多样化提供了便利性。
一些实施例中，在一个像素单元中，沿第一方向X第一子像素的开口区与第二子像素开口区和第三子像素的开口区相互错开，即第二子像素的开口区沿第一方向X与第一子像素的开口和第三子像素的开口没有投影交叠区。如此，可以使子像素之间排列可以做到更为紧凑。另一些实施例中，至少第二子像素远离第四子像素的一侧边的延长线不穿过第三子像素的开口区。例如，第二子像素的开口区可以与第一子像素的开口区沿第一方向X部分交叠，但与第三子像素不交叠。
一些实施例中，位于同一行和/或列的绿色的子像素的中心的连线为非直线或近似直线。例如，如图5及图6所示，位于同一行和/或列的绿色的子像素的中心的连线呈锯齿状。奇数行或列的任一像素组中两个绿色的子像素，与相邻偶数行或列的像素组中最相邻的两个绿色的子像素的中心的连线形成第五虚拟四边形；第五虚拟四边形中的最小内角γ≥60°。如此，使相邻像素组中的绿色的子像素不易太近，进一步地避免因相邻的绿色的子像素距离较近而导致的相邻的两个绿色的子像素难以分辨，被人眼视觉上合二为一的情况。
在本申请的第一方面还提供了一种显示面板，包括上述实施例的像素排布结构。
再次参见图3至图7，本申请的像素排布结构还具有以下的特征。
本申请的像素排布结构，包括所述第一像素单元。所述第一像素单元包括所述第一子像素12、第二子像素14、第三子像素16a和第四子像素16b。第一子像素12、第二子像素14、第三子像素16a和第四子像素16b可以分别为蓝色发光子像素、红色发光子像素和绿色发光子像素中的一种。当然，在其他一些实施例中，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b还可以为发射蓝色、红色和绿色之外其他颜色光的子像素，例如，第三子像素或第四子像素可以为白色或黄色的子像素，在此不作限定。应当理解的是，不同颜色光具有不同的波长范围，波长越短意味着光的能量越高，能量高的光容易引起有机发光材料的衰变，使得发射能量高的光子的子像素更容易衰减。蓝光波长相较于红光波长和绿光波长短，因此，蓝光的能量更高，发射蓝光的有机发光材料更容易发生衰变，导致像素单元中发出的光容易偏红，造成白光色偏现象。且，每个子像素发射的光 通过法布里-珀罗微腔(Fabry-Perot microcavity)效应在阳极和阴极之间重复反射和再反射，进行放大和相长干涉，光的亮度增加，色偏情况进一步被放大。作为一种较佳地实施方式，如图3及图4所示，第一子像素12为蓝色的子像素，第二子像素14为红色的子像素，第三子像素16a和第四子像素16b为绿色的子像素。其中，蓝色的子像素的发光面积大于红色的子像素和绿色的子像素的发光面积，这样，可以一定程度降低因发射不同颜色光的有机发光材料衰减速率不同而造成的显示不良。需要指出，一些实施方式中，绿色的子像素的发光面积可以与红色的子像素的发光面积相等，但由于人眼相较于红光对绿光比较敏感，在另一些实施方式中，绿色的子像素的发光面积可以小于红色的子像素的发光面积，在此不作限定。
在第一像素单元内，具有以第一子像素12、第二子像素14、第三子像素16a和第四子像素16b的各自中心为顶点构成的面积不重叠的共边三角形，且以第一子像素12的中心和第二子像素14的中心为所述共边三角形的共边顶点。具体地，如图3和图4所示，第一子像素12位于第三子像素16a和第四子像素16b中心连线c的一侧，第二子像素14位于第三子像素16a和第四子像素16b中心连线c的另一侧。第一子像素12、第二子像素14、第三子像素16a和第四子像素16b的中心依次连线形成虚拟四边形，第一子像素12、第二子像素14和第三子像素16a的中点连线构成第一三角形(图未标)，第一子像素12、第二子像素14和第四子像素16b的中心连线构成第二三角形。第一三角形和第二三角形以第一子像素的中心和第二子像素的中心连线d作为共同边，即为共边三角形，且两个三角形彼此面积不重叠。作为一种较佳地实施例中，共边三角形为锐角三角形，如此，使像素结构的子像素排布较为均匀，有利于提高显示效果。
其中，第二子像素具有第二长轴和第二短轴，在第一像素单元内，第二子像素沿其长轴方向的中心线不经过第三子像素和/或第四子像素的中心。可以理解，子像素的长轴方向是指子像素的发光区的纵长延伸方向，子像素的短轴指子像素的发光区在与发光区的纵长延伸方向相对的宽度方向。因此，第二子像素沿其长轴方向的中心线是指沿子像素的发光区的纵长延伸方向经过第二子像素中心的直线。例如，如图3所示，第一三角形和第二三角形以第一子像素12的中心和第二子像素14的中心之间的中心连线d共边，第二子像素14沿其长轴方向的中心线是指经过其中心且沿其长轴方向延伸的直线。通过第二子像素沿其长轴方向的中心线不经过第三子像素和/或第四子像素的中心，使第一像素单元内的各子像素能够错位排布，从而有效的改善彩边问题。进一步地，共边三角形的共边的顶点在与该顶点相对的对边上的投影位于所述对边上，且该投影与所述第三子像素的中心和/或第四子像素的中心不重合。例如，如图3所示，第二子像素14的中心(中心连线d的一个顶点)在与其相对的对边e(第一子像素的中心和第三子像素的中心连线)上的投影位于对边e上。且该投影位于第一子像素12的中心和第三子像素16a的中心之间，也即与第三子像素16a的中心不重合。对应地，第一子像素12的中心(中心连线d的另一个顶点)在与其相对的对边b(第二子像素和第四子像素的中心连线)上的投影位于对边b上。且该投影位于第二子像素14的中心和第四子像素16b的中心之间，也即与第四子像素16b的中心不重合。作为一种较佳地实施方式，该共边三角形的共边上的顶点在该顶点对边上的投影接近或者位于所述对边的中心点上。如此，使子像素的排布较为均匀，更进一步避免彩边现象的出现，有利于显示质量的提高。
需要说明的是，共边顶点在对边的投影是指，该顶点沿垂直于该顶点的对边方向上在所述对边上的投影，也即，经过该顶点且与该顶点的对边垂直的垂线和该对边的交点即是前述的顶点在对边的投影。例如，如图3所示，第一三角形和第二三角形的共边d的一个顶点为第二子像素14的中心，经过第二子像素的中心且垂直于与其相对的对边e的垂线，与该对边e的交点即为前述的顶点在与其相对的对边上的投影。
可以理解，像素排布结构直接决定着显示效果，为保证显示均匀，各子像素通常会 沿着行方向和列方向呈一定规则尽可能均匀排布，但像素排布结构也容易出现彩边和视觉颗粒感。采用前述的像素排布结构，可以兼顾子像素的排列均匀性、紧密度和子像素之间的间距，在三者之间寻求一个平衡，有利于降低混色风险、改善彩边，和视觉颗粒感。例如，当形成显示矩阵时，各子像素受前述的限制条件而错开排布，避免发射同种颜色光的子像素单独排成一列，改善了显示边缘的彩边问题。且，错开排布的子像素使位于显示面板圆角处的子像素更能匹配圆角设计，即位于边缘的子像素的边缘连线在圆角处的平滑过渡，与圆角的弧度相切或相吻合，进而改善圆角处的锯齿问题。此外，采用前述的像素排布结构，可以适当拉大同一像素单元中的同色子像素的距离，如将人眼敏感的第三子像素和第四子像素的距离适当拉大，而将第一子像素和第二子像素设置为彼此靠拢，可以避免显示时人眼敏感子像素无法分辨而将多个子像素识别为一个造成的显示颗粒感。
值得强调的是，屏下感光器件接收的光信号的进光量以及对比度均会影响生成的图像质量，采用其他像素排布结构的显示面板，虽然可透光区域较多，使总体的透光面积无差异，但在特定区域内连续的透光区域的面积较小，无法满足屏下感光器件正常工作所需的光透过率。采用前述的像素排布的限制条件，还可以在一个像素单元内错位排布形成透光预留区，有利于实现诸如屏下摄像的显示屏的制作。例如，如图5及图6所示，第一像素单元和第二像素单元中还包括设置在第二子像素14外侧的空白区，该空白区即为前述的透光预留区Z，该区域可以预设为外界光线贯穿到达屏下的感光器件。具体到一个实施例中，所述透光预留区在第一方向上的尺寸范围为10μm～90μm，在第二方向上的尺寸范围为20μm～90μm。
一些实施例中，该像素排布结构还包括多个第二像素单元。第一像素单元和第二像素单元彼此相邻，且多个第一像素单元与多个第二像素单元在第一方向以及第二方向上交替排布。例如，如图5所示，第一方向为X方向，第二方向为Y方向。在第一方向上，第一像素单元和第二像素单元交替排布，在第二方向上，第一像素单元和第二像素单元交替排布。也就是说，在第一方向和第二方向上，任意两个相邻的第一像素单元由一个第二像素单元间隔开来，任意两个相邻的第二像素单元由一个第一像素单元间隔开来。可以理解，在其他一些实施例中，该第一方向和第二方向也可以为其他与行方向和列方向相交的方向，在此不作限定，例如，如图6所示，第一方向与行方向的夹角为45°的方向，第二方向与第一方向相垂直，且与列方向的夹角为45°的方向。
一些实施例中，第二像素单元中各子像素结构旋转预定角度后与所述第一像素单元中各子像素结构成镜像对称。也就是说，第一像素单元中的子像素和第二像素单元中的同色子像素的形状、大小(发光面积)相同，第二像素单元中的子像素沿顺时针或逆时针旋转预定角度后的子像素结构与第一像素单元中对应的子像素的结构镜像对称。其中，所述的预定角度大于0°，小于360°，例如，图4所示的第二像素单元中各子像素排布结构旋转90°后沿第一方向与图3所示的第一像素单元中各子像素排布结构成镜像对称。如此，不仅使在行方向或列方向避免发射同种颜色光的子像素单独排成一列，且弱化了位于同一行或列的子像素的凸出程度，进一步地改善了显示边缘的彩边问题。且同时还可以有效改善色偏，例如，可以将第三子像素和第四子像素设置为人眼敏感颜色的子像素，如绿色的子像素，每一个绿色的子像素均可由红色的子像素和蓝色的子像素围绕，从而使用混色更为均匀，改善了色偏。此外，第二像素单元中各子像素结构旋转预定角度后与第一像素单元中各子像素结构成镜像对称，还可以尽可能使相邻的像素单元之间能够形成面积较大的透光预留区Z(见图6)，有利于提高屏下感光器件的采光面积。可以理解，在另一些实施例中，第一像素单元和第二像素单元的子像素结构也可以相同，在此不作限定。也就是说，像素排布结构中的最小重复单元即为一个像素单元。
进一步地，一些实施例中，在第一方向上，第一像素单元和与之相邻的第二像素单元构成第一像素组。在第二方向上，第一像素单元和与之相邻的第二像素单元构成第二像 素组。换言之，在第一方向，一个第一像素单元和与之相邻的一个第二像素单元构成第一像素组；在第二方向，一个第一像素单元和与之相邻的一个第二像素单元构成第二像素组。具体到如图5、图6及图7所示的实施例中，以像素单元为单位，两个第一像素单元和两个第二像素单元构成一个重复单元，两个第二像素单元分别位于两个第一像素单元几何中心连线的一侧。以像素组为单位，两个相邻的第一像素组或两个相邻的第二像素组构成一个重复单元，多个重复单元沿第一方向和第二方向排布。其中，第一像素组内第三子像素的中心或第四子像素的中心位于第一像素组中的两个第二子像素的中心连线的外侧；和/或第二像素组内第三子像素的中心或第四子像素的中心位于第二像素组内的两个第二子像素的中心连线的外侧。如此，在尽可能保证子像素排布均匀的前提下，使子像素能够错位排布，在重复单元重复排列形成显示矩阵时，进一步地避免同色子像素单独排成一列，且弱化了同一行或列的子像素的凸出程度，从而改善了显示边缘的彩边问题。需要说明的是，为提高分辨率，是利用子像素渲染技术，而为了实现全彩色显示需要向旁边的子像素借用其不能显示的颜色。因此，子像素排布均匀是指，各子像素之间的距离在合理的范围内，避免像素排布结构中部分区域子像素距离过小而紧密，而部分区域子像素距离过大而疏松，导致显示效果不佳。
可以理解，随着刘海屏或者显示屏开孔的技术的应用，显示区域异形边缘区域(例如弧形区域)锯齿感也是影响显示质量的一个因素。本申请的发明人研究发现，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。因此，作为一种实施例方式，多个重复单元可以沿与行方向和列方向倾斜相交的第一方向和第二方向排布，随着重复单元重复排布，可以使位于显示区域异形边缘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，进而能够降低在异形边缘处图像的锯齿感，有利于提高显示面板的显示效果。此外，还可以使位于显示区域异形边缘的子像素包括多种颜色，从而进一步降低显示面板的异形边缘处形成的彩边的情况，进而提高显示面板的显示效果。较佳地，第一方向与第二方向彼此垂直，第一方向与行方向的夹角优选45°。
一些实施例中，第三子像素16a的中心或第四子像素16b的中心位于第一像素单元中第二子像素14中心和与该第一像素单元相邻的第二像素单元中的第二子像素14的中心之间的连线的外侧。换言之，一个像素单元中的第三子像素16a的中心或第四子像素16b的中心位于其所在像素单元中第二子像素14中心和与之相邻的另一像素单元中的第二子像素14的中心之间的连线的外侧。例如，具体到一些实施例中，如图5及图6，第一像素单元中的第二子像素R1的中心和与第一像素单元相邻的第二像素单元中的第二子像素R2的中心的连线的延长线，与第一像素单元中的第三子像素G11的中心和第四子像素G12的中心错开，且第三子像素G11的中心和第四子像素G12的中心位于前述的连线的延长线的两侧。需要说明的是，子像素的中心位于中心连线的外侧是指，子像素的中心与中心之间的连线及其延长线错开，例如，子像素的中心位于中心连线及其延长线的一侧。
作为一种较佳的实施方式，第一子像素和第二子像素可以分别为蓝色的子像素和红色的子像素，第三子像素和第四子像素可以为绿色的子像素，相较于蓝色和红色的子像素，绿色的子像素的发光面积较小。同一像素单元中，第一子像素的中心和第二子像素的中心之间的中心连线d，和第三子像素的中心和第四子像素的中心连线c的长度不等。容易理解，通常发射不同颜色光的子像素的发光面积大小不同，例如，蓝色的子像素的发光面积大于红色的子像素和绿色的子像素的发光面积大小。通过将中心连线d的长度设计为与中心连线c的长度不等，可以保证第一子像素和第二子像素之间的间距，以及第三子像素和第四子像素的间距满足预设条件，以尽可能使各子像素紧密排列，且改善敏感颜色子像素的分布均匀性，提高视觉上的分辨率，提升显示质量。
如图3及图4所示，一个像素单元中，第一子像素的中心与第三子像素中心连线e的长度，不等于同一像素单元中第一子像素的中心与第四子像素中心连线的长度a。具体到一个实施例中，第一子像素为蓝色的子像素、第二子像素为红色的子像素，第三子像素和第四子像素为绿色的子像素。同一像素单元中蓝色子像素与不同的绿色子像素的中心连线长度不同。另一些实施例中，一个像素单元中，第三子像素的中心和第四子像素的中心分别到第二子像素的中心的距离不相等。如此，一方面，使相邻的子像素不易太近，进一步地避免因相邻子像素距离较近而导致的相邻的两个子像素难以分辨，被人眼视觉上合二为一的情况。另一方面，通过第一子像素和第二子像素与第三子像素和第四子像素的中心的连线的长度设置为不同，加剧了子像素的错位排布，在第一像素单元和第二像素单元重复排列形成显示矩阵时，进一步地避免同色子像素单独排成一列，且弱化了同一行或列的子像素的凸出程度，从而改善了显示边缘的彩边问题。
进一步地，第三子像素的中心和第四子像素的中心分别到第一子像素的中心的距离比值为(3～2)：(2～1)。第三子像素的中心和第四子像素的中心分别到所述第二子像素的中心的距离也为(3～2)：(2～1)。可以理解，显示质量影响因素除了彩边、颗粒感，关键因素还有分辨率、均匀性，因此，通过进一步地限定第三子像素和第四子像素的中心到第一子像素和第二子像素的中心的距离之比，使子像素的排布在均匀性、紧凑性、错位程度之间达到一个良好的平衡，使显示质量得到综合提升。
需要说明的是，子像素的中心可以是子像素图形的几何中心，也可以是子像素的发光颜色的中心，在此不作限定。
进一步地，同一像素单元中，沿第一方向和第二方向，相邻的两个子像素之间的最小距离为p，沿第一方向和第二方向，相邻的两个像素单元中最相邻的不同颜色的子像素之间的最小距离也为p。其中，10um<p<30um。如此，一方面，使子像素的排布更为均匀，有利于提高显示质量，另一方面，可以有效的避免相邻子像素之间的发光串色或干扰产生锯齿感。需要说明的是，本申请实施例提供的显示面板，可以为有机发光显示面板，子像素至少包括阳极和阴极，以及位于阳极和阴极之间的发光层，驱动电路向阳极和阴极之间施加电压，激发载流子迁移，作用于发光层，从而发射出光线。显示面板还可以包括像素定义层，像素定义层界定出了多个像素开口，子像素的发光层设于像素开口中，以避免相邻的子像素之间发生串色或干扰。因此，像素开口的面积即为子像素的发光面积，但是，受限于蒸镀技术，为保证发光材料完全蒸镀于像素开口内，通常，掩膜板的开口面积大于像素开口的面积，以留有蒸镀余量。例如，如图3所示，子像素的内侧边称为像素边，即是像素定义层(PDL层)的像素开口的边界，外侧边称为子像素的虚拟边，所述虚拟边是指Mask(掩膜板)的蒸镀开口的边界。故，本申请的实施例中，子像素之间的间距是指两个子像素的像素边之间的距离。而具体到如图3及图4所示的实施例中，相邻的两个子像素之间具有彼此相邻且平行的两条像素边，则相邻的两个子像素之间最小距离为该彼此相邻且平行的两条像素边之间的垂线距离。
进一步地，第一像素单元中的第二子像素与沿第一方向相邻排布的第二像素单元的第三子像素之间的最小距离为q，p<q<3p。如此，可以保证透光预留区拥有足够大小，进而满足屏下感光器件的正常工作所需要的进光量。
如图5、6及图7所示，作为一种较佳的实施方式，第一子像素、第二子像素、第三子像素和第四子像素均可以为矩形或类矩形，第一子像素、第二子像素、第三子像素和第四子像素的长轴方向(延伸方向)与行方向和列方向相交。这样，一方面，相较于其他子像素形状，子像素之间排列可以做到紧密排布，且避免同色子像素独立成一行，有效改善彩边现象。另一方面，使位于显示面板异形边缘的子像素更能匹配圆角设计，即子像素的倾斜与圆角的弧度相切或相吻合，实现各子像素边缘在圆角处的平滑过渡，进而改善圆角处的锯齿问题。较佳地，第一子像素、第二子像素、第三子像素和第四子像素的延伸方向 与第一方向相平行，与行方向或列方向的夹角为30°-60°。这样，可以进一步使子像素的倾斜与圆角的弧度相切或相吻合，实现各子像素边缘在圆角处的平滑过渡，进一步改善圆角处的锯齿问题。需要强调的是，由于人眼对水平或垂直方向上的画面质量较为敏感，而对与水平方向的夹角为45°的方向上的画面质量较为不敏感，因此，作为一种优选的实施方式，如图7所示，第一方向与行方向的夹角为45°，如此可以进一步提高整体显示质量。特别指出的是，掩膜板受力通常沿行或列方向传递，例如，张网力F沿行方向传递，对应子像素相对行或列方向倾斜设置的掩膜板的开口可以将受力在行方向和列方向分解，从而避免FMM张网力F集中造成的开口变形，降低了掩膜板的制作难度和张网难度。且掩膜板的开口倾斜设置，在同样长度和宽度的掩膜板中，可以设置更多的开口，降低了掩膜的制作成本。
当然，第一子像素、第二子像素、第三子像素和第四子像素还可以为其他形状，在此不作限定，例如，第一子像素可以为正方形，第二子像素、第三子像素和第四子像素为长方形。
本申请的一些实施例中，共边三角形的共边上至少一个顶点在该顶点对边上的投影，整体位于该对边对应的两子像素轮廓与该对边的交点之间。换言之，经过共边三角形的共边上的顶点且垂直于该顶点对边的直线与该顶点对边的交点，位于该顶点对边对应的两子像素轮廓与该顶点对边的交点之间。进一步地，在一个像素单元内，第二子像素沿其长轴方向侧边的延长线或该侧边的切线，与第三子像素和/或第四子像素整体不相交。例如，共边三角形的共边上的顶点对应的子像素在该顶点对边上的投影可以整体位于该顶点对边对应的两子像素轮廓与该顶点对边的交点之间。如此，使第二子像素沿其长轴方向侧边的延长线或该侧边的切线，可以与第三子像素和/或第四子像素整体不相交。具体到一些实施例中，如图3及图4所示，共边的两顶点分别为第一子像素的中心和第二子像素的中心。为使子像素的排布更为均匀且降低制作难度，彼此相邻的两个子像素具有彼此相对且平行的两个像素边。例如，第一子像素和第三子像素具有彼此相对平行的两条像素边，所述两条像素边即为第一子像素和第三子像素的轮廓边界。第二子像素朝向对边e的投影整体位于对边e与第一子像素的轮廓和第二子像素轮廓的交点之间，也即第二子像素朝向对边e的投影，位于对边e与第一子像素和第二子像素的两条彼此相对且平行的像素边的交点之间。可以理解，在图3所示的实施例中，第一子像素朝向对边b的投影整体并没有位于对边b与第二子像素和第三子像素的中心连线的之间，但并不妨碍对该技术构思的理解，在另一些实施例中，第一子像素朝向对边b的投影整体，可以位于对边b与第二子像素和第三子像素的两条彼此且平行的像素边的交点之间。如此，一方面使子像素排布更为均匀，另一方面，使子像素错位排布进一步降低了彩边现象。
同一像素单元中，第一子像素具有第一长轴和第一短轴；第三子像素具有第三长轴和第三短轴，第四子像素具有第四长轴和第四短轴。也就是说，各子像素均为具有长轴和短轴的规则图形或不规则图形，例如矩形或类矩形。如此，一方面，相较于其他子像素形状，子像素之间排列可以做到紧密错位排布，且弱化了子像素的凸出程度，有效改善彩边现象。较佳地，第三子像素和第四子像素为同色子像素，例如均为绿色的子像素，则第三长轴和第四长轴彼此平行且长度相等，第三短轴和第四短轴彼此平行且长度相等。进一步地，第一长轴和第一短轴的比值在1.5～1之间；第二长轴和第二短轴的比值在5～1之间；第三长轴和第三短轴的比值在5～1之间。例如，如图3及图4所示的实施例中，第一子像素为正方形，第一长轴和第一短轴之比为1，第二子像素、第三子像素和第四子像素均为长方形，第二子像素、第三子像素和第四子像素的长短轴之比在5：1之间。如此，可以尽可能保证开口率的前提下，相应的使各子像素能够错位排布，以尽可能降低彩边现象。且还可以尽可能使相邻的子像素之间能够形成面积较大的透光预留区，有利于提高屏下感光器件的采光面积。
一些实施例中，在第一方向上相邻的第一像素单元和第二像素单元中，第一像素单元内的第二子像素R1与该第二像素单元内的第三子像素G21之间的距离大于该第一像素单元内的第三子像素G11和第四子像素G12与该第二子像素R1之间的距离。如此，进一步保证每一重复单元中可以形成连续且面积可以满足屏下感光器件正常工作的透光预留区Z，从而提高了显示面板的透光率，为显示面板的功能多样化提供了便利性。作为一种实施方式，透光预留区Z的面积大于一个第一子像素R1/R2的发光面积。
如图7和图8所示，该像素排布结构包括第一子像素、第二子像素、第三子像素和第四子像素，其中对位设置的两所述第一子像素中心、对位设置的两所述第二子像素中心为顶点连线形成虚拟四边形，所述虚拟四边形包括相向设置的两等边、相向设置且连接等边顶点的短边和长边；所述短边与所述长边非平行。
所述虚拟四边形内布设有第三子像素或者第四子像素，所述第三子像素与所述第四子像素发光颜色相同。
所述虚拟四边形以其内布设第三子像素还是第四子像素，分为其内布设第三子像素的第一虚拟四边形和其内布设第四子像素的第二虚拟四边形，所述第一虚拟四边形和相邻的第二虚拟四边形共边。
所述第一虚拟四边形和相邻的第二虚拟四边形中，第一子像素的中心为顶点构成的四个内角之和等于360°，且第二子像素的中心为顶点构成的四个内角之和等于360°。如此，通过虚拟四边形的角度限制各子像素之间的间距和相对位置，可以尽可能地使子像素排布均匀，且保持子像素错位排布，在显示均匀、紧凑和改善彩边问题上达到一个平衡。
所述第一虚拟四边形的第一等边长度不等于所述第二虚拟四边形的第二等边长度不等，所述第一虚拟四边形的短边长度等于所述第二虚拟四边形的短边长度，所述第一虚拟四边形的长边长度等于所述第二虚拟四边形的长边长度。
在列方向上，所述第一虚拟四边形与相邻的第二虚拟四边形以短边或者长边为共边。在行方向上，所述第一虚拟四边形与相邻的倒置第一虚拟四边形以第一等边为共边，所述第二虚拟四边形与相邻的倒置第二虚拟四边形以第二等边为共边。
所述像素排布结构包括由四个虚拟四边形以共享边的方式排布形成的虚拟多边形，所述四个虚拟四边形具体包括第一虚拟四边形30、第二虚拟四边形40、倒置第一虚拟四边形30后得到的第三虚拟四边形50和倒置第二虚拟四边形40后得到的第四虚拟四边形60。
所述第一虚拟四边形沿行方向与第三虚拟四边形共享第一等边，在列方向与第二虚拟四边形共享短边。第三虚拟四边形沿列方向与第四虚拟四边形共享长边，在行方向第四虚拟四边形与第二虚拟四边形共享第二等边。
第一等边的长度与第二等边的长度不等。
第一虚拟四边形、第二虚拟四边形、第三虚拟四边形和第四虚拟四边形的非共边构成了虚拟多边形的各个边。
第二子像素位于各虚拟四边形的第一顶点位置处，第一子像素位于各虚拟四边形的第二顶点位置处，第一顶点和第二顶点交替且间隔设置，第三子像素或第四子像素位于各虚拟四边形内。
所述虚拟四边形内以两所述第一子像素的中心连线为第一对角线、两所述第二子像素的中心连线为第二对角线，所述虚拟四边形内所述第三子像素和/或第四子像素的中心偏离所述第二对角线。
进一步地，每一前述的虚拟四边形的任一边与行或列方向不平行；或者每一前述的虚拟四边形的任意两条对边彼此不平行；或者每一前述的虚拟四边形的任意两个内角不相等。如此，第一虚拟四边形、第二虚拟四边形、第三虚拟四边形和第四虚拟四边形均为不规则的四边形，从而可以在满足子像素排布紧凑的前提下，形成较大的透光区域，从而进一步提高了显示面板的透光率，为显示面板的功能多样化提供了便利性。
如图3及图4所示，一个像素单元中，第二子像素14具有分别与第三子像素16a和第四子像素16b彼此相对的第一边和第二边、与第一边相邻且与第二边相对的第三边，以及与第一边相对且与第二边和第三边相连的第四边。其中，第二边和第四边的延长线与所述第三子像素16a错开，第一边和第四边的延长线与第四子像素16b错开。也就是说，第三子像素16a和第四子像素16b分别位于第二子像素14相应的边延长线之间。如此，尽可能地保证子像素排布紧凑，且弱化了显示边缘的子像素的凸出程度，有效改善了显示边缘的彩边问题。
位于同一行和/或列的第三子像素的中心连线为非直线，同一行和/或列的第四子像素的中心连线为非直线。例如，如图5、图6及图8所示，位于同一行和/或列的绿色的子像素的中心连线呈锯齿状。奇数行或列的任一像素组中两个绿色的子像素，与相邻偶数行或列的像素组中最相邻的两个绿色的子像素的中心连线形成第五虚拟四边形；第五虚拟四边形中的最小内角γ≥60°。如此，使相邻像素组中的绿色的子像素不易太近，进一步地避免因相邻的绿色的子像素距离较近而导致的相邻的两个绿色的子像素难以分辨，被人眼视觉上合二为一的情况。
可以理解，在一些实施例中，同一行和/列的第一子像像素的中心连线可以直线，同一行和/列的第二子像素的中心连线可以为直线。如此，可以使子像素排布更为均匀，有利于提高显示质量。
本申请的第二方面还提供了一种显示面板，包括上述实施例中的像素排布结构。
再次参见图3至图7，并一并参见图8，本申请的所述像素排布结构还包括以下特征。
本申请的所述像素排布结构，包括所述第一子像素12、第二子像素14、第三子像素16a和第四子像素16b。第一子像素12、第二子像素14、第三子像素16a和第四子像素16b可以分别为蓝色发光子像素、红色发光子像素和绿色发光子像素中的一种。当然，在其他一些实施例中，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b还可以为发射蓝色、红色和绿色之外其他颜色光的子像素，例如，第三子像素16a或第四子像素16b可以为白色或黄色的子像素，在此不作限定。应当理解的是，不同颜色光具有不同的波长，波长越高意味着光的能量越高，能量高的光容易引起有机发光材料的衰变，使得发射能量高的光子的子像素更容易衰减。蓝光波长相较于红光波长和绿光波长短，因此，蓝光的能量更高，发射蓝光的有机发光材料更容易发生衰变，导致像素单元中发出的光容易偏红，造成白光色偏现象。且，每个子像素发射的光通过法布里-珀罗微腔(Fabry-Perot microcavity)效应在阳极和阴极之间重复反射和再反射，进行放大和相长干涉，光的亮度增加，色偏情况进一步被放大。作为一种较佳地实施方式，如图3所示，第一子像素12为蓝色的子像素，第二子像素14为红色的子像素，第三子像素16a和第四子像素16b为绿色的子像素。其中，蓝色的子像素的发光面积大于红色的子像素和绿色的子像素的发光面积，这样，可以一定程度降低因发射不同颜色光的有机发光材料衰减速率不同而造成的显示不良。需要指出，一些实施方式中，绿色的子像素的发光面积可以与红色的子像素的发光面积相等，但由于人眼相较于红光对绿光比较敏感，在另一些实施方式中，绿色的子像素的发光面积可以小于红色的子像素的发光面积，在此不作限定。
对位设置的两个第一子像素12的中心、对位设置的两个第二子像素14的中心为顶点连线形成虚拟四边形。也就是说，两个第一子像素12的中心作为该虚拟四边形的一组对角顶点，两个第二子像素14的中心作为该虚拟四边形的另一组对角顶点。例如，图7所示，在第一虚拟四边形30中，两个第一子像素沿第二方向排布，两个第二子像素沿第一方向排布，两个第一子像素的中心和两个第二子像素的中心依次连线构成所述的虚拟四边形。该第一虚拟四边形包括相向设置的两等长对边、相向设置且连接等长对边顶点的短边和长边。继续参阅图7，在第一虚拟四边形30中，沿列方向，一个第一子像素12和第 二子像素14的中心连线为第一等长对边，另一个第一子像素12和第二子像素14的中心连线为第二等长对边。沿行方向，一个第一子像素12和第二子像素14的中心连线为该虚拟四边形的长边，另一个第一子像素12和第二子像素14的中心连线为虚拟四边形的短边。
该虚拟四边形内布设有一个第三子像素或者一个第四子像素，第三子像素与第四子像素发光颜色相同。具体地，该像素排布结构包括多个虚拟四边形，多个虚拟四边形包括相邻且共边的第一虚拟四边形和第二虚拟四边形；第一虚拟四边形内设有一个所述第三子像素，第二虚拟四边形内设有一个所述第四子像素。具体到如图7所示的实施例中，四个虚拟四边形以共享边的方式排布，所述四个虚拟四边形具体包括第一虚拟四边形30、第二虚拟四边形40、倒置第一虚拟四边形30后得到的第三虚拟四边形50和倒置虚拟第二四边形40后得到的第四虚拟四边形60。第一虚拟四边形30沿行方向与第三虚拟四边形50共享第一共享边g，在列方向与第二虚拟四边形40共享第二共享边h。第四虚拟四边形60沿列方向与第三虚拟四边50形共享第三共享边j，第四虚拟四边形60在行方向与第二虚拟四边形40共享第四共享边i。各虚拟四边形远离共享边的侧边构成了虚拟多边形的各个边。第二子像素14位于各虚拟四边形的第一顶点位置处，第一子像素12位于各虚拟四边形的第二顶点位置处，第一顶点和第二顶点交替且间隔设置。第一虚拟四边形30和第二虚拟四边形40内设有一个第三子像素16a，第三虚拟四边形50和第四虚拟四边形60内设有一个第四子像素16b。
其中，该虚拟四边形的短边与该虚拟四边形的长边非平行。可以理解，像素排布结构直接决定着显示效果，为保证显示均匀，例如图1所示的像素排布结构，各子像素通常会沿着行方向和列方向呈一定规则尽可能均匀排布，但现有的像素排布结构也容易出现色偏、彩边。采用前述的像素排布结构，虚拟四边形的具有一组等长对边，一组长度不同的长边和短边，且长边和短边非平行，使各子像素可以错位排布，且可以兼顾子像素的排列均匀性、紧密度和子像素之间的间距，在三者之间寻求一个平衡，有利于降低混色风险、改善彩边和边缘锯齿问题。例如，当形成显示矩阵时，各子像素受前述的限制条件而错开排布，避免发射同种颜色光的子像素单独排成一列，改善了显示边缘的彩边问题。且，错开排布的子像素使位于显示面板圆角处的子像素更能匹配圆角设计，即位于边缘的子像素的边缘连线在圆角处的平滑过渡，与圆角的弧度相切或相吻合，进而改善圆角处的锯齿问题。此外，可以将第三子像素和第四子像素设置为人眼敏感的绿色子像素，其周围由蓝色和红色的子像素围绕，从而使混色更均匀，避免色偏。
一些实施例中，该第一虚拟四边形和相邻的第二虚拟四边形中，以第一子像素的中心为顶点的四个内角之和等于360°；以第二子像素的中心为顶点的四个内角之和等于360°。如此，通过虚拟四边形的角度限制各子像素之间的间距和相对位置，可以尽可能地使子像素排布均匀，且保持子像素错位排布，在显示均匀、紧凑和改善彩边问题上达到一个平衡。
进一步地，第一虚拟四边形的第一等长对边长度不等于第二虚拟四边形的第二等长对边长度；第一虚拟四边形的长边长度等于第二虚拟四边形的长边长度；第一虚拟四边形的短边长度等于所述第二虚拟四边形的短边长度。如此，在形成显示矩阵时，使子像素能够紧凑排布，且各子像素之间能够保持较为均匀和规律的排布，有利于显示质量的提高。具体地，在列方向上，第一虚拟四边形与相邻的第二虚拟四边形以短边或者长边为共边。具体到如图7所示的实施例中，在行方向上，第一虚拟四边形30与相邻的第三虚拟四边形50倒置，且以第一等长对边共边，第二虚拟四边形40与相邻的第四虚拟四边形60倒置，且以第二等长对边为共边。在列方向上，虚拟四边形30与相邻的虚拟四边形40共享短边，第三虚拟四边形50与相邻的第四虚拟四边形60共享长边。也就是说，相邻的第一虚拟四边形或第二虚拟四边形沿预设角度翻转180度的结构相同。如此，在形成显示矩阵时，一方面各子像素之间排布较为紧凑，另一方面，子像素排布具有规律且重复单元整体 上更接近规则图形，从而有利于显示质量的提高。再一方面，能够弱化子像素的凸出程度，有效地改善了彩边。
可以理解，另一些实施例中，第一等长对边的长度也可以与第二等长对边的长度相等，在此不作限定。如此，进一步地加剧了子像素的错位排布，有利于改善彩边。
本申请的实施例中，该像素结构包括第一像素单元和第二像素单元，第一像素单元和第二像素单元彼此相邻，且多个第一像素单元与多个第二像素单元在第一方向以及第二方向上交替排布。例如，如图7及图8所示，在第一方向上，第一像素单元和第二像素单元交替排布，在第二方向上，第一像素单元和第二像素单元交替排布。也就是说，在第一方向和第二方向上，任意两个相邻的第一像素单元由一个第二像素单元间隔开来，任意两个相邻的第二像素单元由一个第一像素单元间隔开来。进一步地，第一像素单元和第二像素单元的各子像素结构在相对旋转90度后镜像对称。也就是说，第一像素单元中的子像素和第二像素单元中的同色子像素的形状、大小(发光面积)相同，第二像素单元中的子像素沿顺时针或逆时针旋转预定角度后的子像素结构与第一像素单元中对应的子像素的结构镜像对称。其中，所述的预定角度大于0°，小于360°，例如，图4所示的第二像素单元中各子像素排布结构旋转90°后沿第一方向与图3所示的第一像素单元中各子像素排布结构成镜像对称。如此，不仅使在行方向或列方向避免发射同种颜色光的子像素单独排成一列，且弱化了位于同一行或列的子像素的凸出程度，进一步地改善了显示边缘的彩边问题。且同时还可以有效改善色偏，例如，可以将第三子像素和第四子像素设置为人眼敏感颜色的子像素，如绿色的子像素，每一个绿色的子像素均可由红色的子像素和蓝色的子像素围绕，从而使用混色更为均匀，改善了色偏。此外，第二像素单元中各子像素结构旋转预定角度后与第一像素单元中各子像素结构成镜像对称，还可以尽可能使相邻的像素单元之间能够形成面积较大的透光预留区Z(见图7)，有利于提高屏下感光器件的采光面积。可以理解，在另一些实施例中，第一像素单元和第二像素单元的子像素结构也可以相同，在此不作限定。也就是说，像素排布结构中的最小重复单元即为一个像素单元。
其中，在每一个像素单元内，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b的各自中心为顶点构成两个共边但不交叠的锐角三角形，且以第一子像素12的中心和第二子像素14的中心为所述共边三角形的共边顶点。具体地，如图3和图4所示，第一子像素12位于第三子像素16a和第四子像素16b中心连线c的一侧，第二子像素14位于第三子像素16a和第四子像素16b中心连线c的另一侧。第一子像素12、第二子像素14、第三子像素16a和第四子像素16b的中心依次连线形成虚拟四边形，第一子像素12、第二子像素14和第三子像素16a的中点连线构成第一三角形(图未标)，第一子像素12、第二子像素14和第四子像素16b的中心连线构成第二三角形。第一三角形和第二三角形以第一子像素12的中心和第二子像素14的中心连线d作为共同边，且两个三角形彼此面积不重叠。
其中，沿垂直于第一子像素12和第三子像素16a的中心连线方向，第二子像素14与第三子像素16a未设置在同一排。也就是说，在垂直于第一子像素12和第三子像素16a的中心连线方向，第二子像素14与第三子像素16a错开排布。换言之，前述的虚拟四边形内以两第一子像素的中心连线为第一对角线、两第二子像素的中心连线为第二对角线，虚拟四边形内第三子像素和/或第四子像素的中心偏离第二对角线。具体到实施例中，第一子像素12和第三子像素16a沿与第一方向垂直的第二方向Y排布，沿垂直于第一子像素12和第三子像素16a的中心连线方向，即第一方向X，第二子像素14与第三子像素16a错开排布。前述的虚拟四边形的顶点分设在第一像素单元中的第一子像素中心、第二子像素中心以及与第一像素单元相邻的两第二像素单元中的第一子像素中心或第二子像素的中心；或者，虚拟四边形的顶点分设在第二像素单元中的第一子像素中心、第二子像素中心以及与第二像素单元相邻的两第一像素单元中的第一子像素中心或第二子像素的中心。 如此，不仅使在行方向或列方向避免发射同种颜色光的子像素单独排成一列，且弱化了位于同一行或列的子像素的凸出程度，进一步地改善了显示边缘的彩边问题。
值得强调的是，屏下感光器件接收的光信号的进光量以及对比度均会影响生成物体的图像质量，采用其他像素排布结构的显示面板，虽然可透光区域较多，使总体的透光面积无差异，但在特定区域内连续的透光区域的面积较小，无法满足屏下感光器件正常工作所需的光透过率。由于第二子像素14和第三子像素16a错开排布，则在第二子像素14的外侧形成透光预留区，有利于实现诸如屏下摄像的显示屏的制作。具体而言，如图7和图8所示，第二子像素R1/R2外侧的空白区即为前述的透光预留区。具体到一个实施例中，所述透光预留区在第一方向上的尺寸范围为10μm～90μm，在第二方向上的尺寸范围为20μm～90μm。
在同一像素单元中，沿垂直于第一子像素12和第三子像素16a的中心连线方向，第一子像素12和第二子像素14也未设置在同一行。也就是说，沿垂直于第一子像素12和第三子像素16a的中心连线方向，第二子像素14和第一子像素12也错位排布。进一步地说，第二子像素14的中心作为共边三角形的共边的一个顶点，在与该顶点相对的对边上的投影位于所述对边上，且该投影与所述第三子像素16a的中心和第一子像素12的中心不重合。例如，如图7所示，第二子像素14的中心(中心连线d的一个顶点)在与其相对的对边e(第一子像素12的中心和第三子像素16a的中心连线)上的投影位于对边e上。且该投影位于第一子像素12的中心和第三子像素16的中心之间，也即与第三子像素16a的中心不重合。如此，保证了各子像素之间的完全错位排布，进一步避免同色子像素单独成一行，且弱化了子像素的凸出情况，避免了彩边现象的出现，有利于显示质量的提高。
需要说明的是，共边顶点在对边的投影是指，该顶点沿垂直于该顶点的对边方向上在所述对边上的投影，也即，经过该顶点且与该顶点的对边垂直的垂线和该对边的交点即是前述的顶点在对边的投影。例如，如图7所示，第一三角形和第二三角形的共边d的一个顶点为第二子像素14的中心，经过第二子像素14的中心且垂直于与其相对的对边e的垂线，与该对边e的交点即为前述的顶点在与其相对的对边上的投影。
如图3及图4所示，在同一像素单元中，第一子像素12和第二子像素14的中心连线e与第三子像素16a和第四子像素16b的中心连线c相交但不垂直。容易理解，第一子像素12、第二子像素14、第三子像素16和第四子像素16b的中心连线形成一个虚拟四边形，第一子像素12与第二子像素14的中心连线c，以及第三子像素16a和第四子像素16b的中心连线d为前述的虚拟四边形的对角线。由于第二子像素14和第三子像素16a在第一方向上错位排布，且该虚拟四边形的对角线不垂直，则使像素单元中的各子像素可以紧密排布，且加剧了错位排布程度，进一步地弱化了显示彩边。作为一种较佳的实施方式，第一子像素12和第二子像素14可以分别为蓝色的子像素和红色的子像素，第三子像素16a和第四子像素16b可以为绿色的子像素，相较于蓝色子像素，绿色的子像素的发光面积较小。同一像素单元中，第一子像素12的中心和第二子像素14的中心的连线d，和第三子像素16a的中心和第四子像素16b的中心连线c的长度不等。容易理解，通常发射不同颜色光的子像素的发光面积大小不同，例如，蓝色的子像素的发光面积大于红色的子像素和绿色的子像素的发光面积大小。通过将中心连线d的长度设计为与中心连线c的长度不等，可以保证第一子像素12和第二子像素14之间的间距，以及第三子像素16a和第四子像素16b的间距满足预设条件，以尽可能使各子像素紧密排列，且改善敏感颜色子像素的分布均匀性，提高视觉上的分辨率，提升显示质量。
如图3及图4所示，同一像素单元中，第一子像素12的中心与第三子像素16a中心连线e的长度，不等于同一像素单元中第一子像素12的中心与第四子像素16b中心连线的长度a。具体到一个实施例中，第一子像素12为蓝色的子像素、第二子像素14为红色的子像素，第三子像素16a和第四子像素16b为绿色的子像素。同一像素单元中蓝色子像 素与不同的绿色子像素的中心连线长度不同。另一些实施例中，一个像素单元中，第三子像素16a的中心和第四子像素16b的中心分别到第二子像素14的中心的距离不相等。如此，一方面，使相邻的子像素不易太近，进一步地避免因相邻子像素距离较近而导致的相邻的两个子像素难以分辨，被人眼视觉上合二为一的情况。另一方面，通过第一子像素12和第二子像素14与第三子像素16a和第四子像素16b的中心的连线的长度设置为不同，加剧了子像素的错位排布，在第一像素单元和第二像素单元重复排列形成显示矩阵时，进一步地避免同色子像素单独排成一列，且弱化了同一行或列的子像素的凸出程度，从而改善了显示边缘的彩边问题。
同一像素单元中，第三子像素16a的中心和第四子像素16b的中心分别到第一子像素12的中心的距离比值为(3～2)：(2～1)。第三子像素16a的中心和第四子像素16b的中心分别到所述第二子像素14的中心的距离也为(3～2)：(2～1)。可以理解，显示质量影响因素除了彩边、颗粒感，关键因素还有分辨率、均匀性，因此，通过进一步地限定第三子像素16a和第四子像素16b的中心到第一子像素12和第二子像素14的中心的距离之比，使子像素的排布在均匀性、紧凑性、错位程度之间达到一个良好的平衡，使显示质量得到综合提升。需要说明的是，子像素的中心可以是子像素图形的几何中心，也可以是子像素的发光颜色的中心，在此不作限定。
示例地，第三子像素16a和第四子像素16b的发光面积可以相同。例如，第三子像素16a和第四子像素16b可以设置为人眼敏感颜色的子像素，这样，可以尽可能提高分辨率的同时，使显示更为均匀。进一步地，第一子像素12、第三子像素16a和第四子像素16b的发光面积也可以相同。如此，有利于子像素排布整体上更为紧凑和均匀，提高了显示效果。作为一种优选的实施方式，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b均可以为矩形或类矩形，第二子像素14的长轴方向与垂直于第一子像素12和第三子像素16的中心连线方向彼此平行。具体地，如图3及图7所示，第二子像素14的长轴方向平行于第一方向，第一子像素12和第三子像素16a的中心连线方向平行于第二方向，第一方向垂直于第二方向。这样，一方面，相较于其他子像素形状，子像素之间排列可以做到紧密排布，且避免同色子像素独立成一行，有效改善彩边现象。另一方面，使位于显示面板异形边缘的子像素更能匹配圆角设计，即子像素的倾斜与圆角的弧度相切或相吻合，实现各子像素边缘在圆角处的平滑过渡，进而改善圆角处的锯齿问题。
较佳地，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b的延伸方向与第一方向相平行，与行方向或列方向的夹角为30°-60°。这样，可以进一步使子像素的倾斜与圆角的弧度相切或相吻合，实现各子像素边缘在圆角处的平滑过渡，进一步改善圆角处的锯齿问题。需要强调的是，由于人眼对水平或垂直方向上的画面质量较为敏感，而对与水平方向的夹角为45°的方向上的画面质量较为不敏感，因此，作为一种优选的实施方式，第一方向与行方向的夹角为45°，如此可以进一步提高整体显示质量。特别指出的是，掩膜板受力通常沿行或列方向传递，例如，张网力F沿行方向传递，对应子像素相对行或列方向倾斜设置的掩膜板的开口可以将受力在行方向和列方向分解，从而避免FMM张网力F集中造成的开口变形，降低了掩膜板的制作难度和张网难度。且掩膜板的开口倾斜设置，在同样长度和宽度的掩膜板中，可以设置更多的开口，降低了掩膜的制作成本。
当然，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b还可以为其他形状，在此不作限定，例如，如图3及图7，第一子像素12可以为正方形，第二子像素14、第三子像素16a和第四子像素16b为长方形。
需要说明的是，类矩形是指，由于工艺限制或者为了掩膜板的制作便利，子像素的形状可能不是严格的矩形，而是大致为矩形，例如，具有圆角的圆角矩形或切角矩形。其中，圆角矩形是矩形的顶角被倒圆角形成的形状，切角矩形是矩形的顶角被切掉一个或多个所 形成的形状。将子像素的形状设置为类矩形可以更加灵活地调整子像素的开口率，并满足掩膜板在制作时的限制条件。
同一像素单元中，第一子像素12具有第一长轴和第一短轴；第二子像素14具有第二长轴和第二短轴；第三子像素16a具有第三长轴和第三短轴；第四子像素16b具有第四长轴和第四短轴。也就是说，各子像素均为具有长轴和短轴的规则图形或不规则图形，例如矩形或类矩形。较佳地，第三子像素16a和第四子像素16b为同色子像素，例如均为绿色的子像素，则第三长轴和第四长轴彼此平行且长度相等，第三短轴和第四短轴彼此平行且长度相等。进一步地，第一长轴和第一短轴的比值在1.5～1之间；第二长轴和第二短轴的比值在5～1之间；第三长轴和第三短轴的比值在5～1之间。例如，如图3及图4所示的实施例中，第一子像素12为正方形，第一长轴和第一短轴之比为1，第二子像素14、第三子像素16a和第四子像素16b均为长方形，第二子像素14、第三子像素16a和第四子像素16b的长短轴之比在5：1之间。如此，可以尽可能保证开口率的前提下，相应的使各子像素能够错位排布，以尽可能降低彩边现象。且还可以尽可能使相邻的子像素之间能够形成面积较大的透光预留区Z，有利于提高屏下感光器件的采光面积。
需要说明的是，子像素的长轴的长度是指子像素的发光区纵长延伸方向的最大尺寸，子像素的短轴的长度是指子像素的发光区在与发光区纵长延伸方向相对的宽度方向的最大尺寸。
第一长轴、第二长轴、第三长轴和第四长轴两两平行。具体而言，沿子像素的长轴方向，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b分别具有一组对边，多组对边之间彼此平行。沿子像素的短轴方向，第一子像素12、第二子像素14、第三子像素16a和第四子像素16b分别具有另一组对边，多组另一组对边彼此平行。例如，如图3及图7所示的实施例中，第一子像素12的形状为正方形，第二子像素14、第三子像素16a和第四子像素16b的形状为矩形，第一子像素12的第一长轴和第一短轴长度之比为1，第一长轴、第二长轴、第三长轴和第四长轴两两平行。第一子像素12具有分别与第三子像素16a和第四子像素16b彼此相对的第一边和第二边、与第一边相邻且与第二边相对的第三边，以及与第一边相对且与第二边和第三边相连的第四边。其中，第一子像素12的第一边和第四边与第二子像素12的长边彼此平行，且与第三子像素16a和第四子像素16b的长边彼此平行。如此，有利于子像素均匀排布，进而提高了显示质量。
在像素单元内，第一子像素12靠近像素单元边缘的一条边的延长线与第三子像素16a靠近像素单元同侧边缘的一条短边的延长线重合。第一子像素12靠近像素单元边缘的另一条边的延长线与第四子像素16b靠近像素单元同侧边缘的一条长边的延长线重合。具体到实施例中，一个像素单元中，第一子像素12的第三边与第三子像素16a的短边共线，第一子像素12的第四边与第四子像素16b的长边共线。如此，尽可能地保证第一像素单元呈规则形状，使子像素排布更紧凑和均匀。进一步地，一些实施例中，第一子像素12的第二边的延长线与所述第三子像素16a错开，第一边的延长线与第四子像素16b错开。如此，保证了子像素之间的错位程度，弱化了显示边缘的子像素的凸出程度，有效改善了显示边缘的彩边问题。
进一步地，一些实施例中，第一子像素12、第三子像素16a和第四子像素16b的长边长度与第二子像素14的边长也可以相同。如此，进一步的使第一像素单元呈规则形状，使子像素排布更紧凑和均匀。
第二子像素14的两条长边中的至少一条长边的延长线穿过第一子像素12与所述第三子像素16a之间的间隙。进一步地，第二子像素14的一条长边的延长线穿过第一子像素12与第三子像素16a之间的间隙，第二子像素14的另一条长边的延长线与第一子像素12的靠近第三子像素16a的边重合。例如，可以将第二子像素14的一条长边的延长线穿过第一子像素12和第三子像素16a之间。第二子像素14的另一条长边的延长线与第一子像 素12的第一边共线。如此，使子像素排布均匀的前提下，尽可能保证透光预留区的大小，有利于例如屏下摄像功能的实现。当然，另一些实施例中，第二子像素14的两条长边的延长线均穿过第一子像素12与第三子像素16a之间的间隙。也就是说，将第二子像素14沿第一方向平移能够穿过第一子像素12和第三子像素16a之间。
位于同一行和/或列的第三子像素16a的中心连线为非直线或近似直线，同一行和/或列的第四子像素16b的中心连线为非直线或近似直线。例如，如图7及图8所示，位于同一行和/或列的绿色的子像素的中心连线可以呈锯齿状。如此，一方面，弱化了子像素的凸出程度，改善了彩边；另一方面，使相邻像素组中的绿色的子像素不易太近，进一步地避免因相邻的绿色的子像素距离较近而导致的相邻的两个绿色的子像素难以分辨，被人眼视觉上合二为一的情况。
可以理解，在一些实施例中，同一行和/列的第一子像像素的中心连线可以直线，同一行和/列的第二子像素14的中心连线可以为直线。如此，可以使子像素排布更为均匀，有利于提高显示质量。
进一步地，沿第一方向和第二方向，排布在同一排相邻的第三子像素16a和第四子像素16b的长轴方向不同。例如，如图4所示，第一方向和第二方向为与水平行方向和竖直列方向倾斜设置的方向，沿第一方向和第二方向，排布在同一排相邻的两个第二子像素R1和R2的长轴方向彼此相反。相应地，沿第一方向和第二方向排布的相邻的第三子像素16a和第四子像素16b的长轴方向也不同。如此，一方面，以尽可能使各子像素紧密排列的同时，加剧了子像素的错位排布，有效改善了色偏。另一方面，避免同色子像素距离过近而造成人眼识别为一个形成的颗粒感。
第一像素单元中的第三子像素16a的中心或第四子像素16b的中心位于第一像素单元中第二子像素14中心和与该第一像素单元相邻的第二像素单元中的第二子像素14的中心连线的外侧。换言之，一个像素单元中的第三子像素16a的中心或第四子像素16b的中心位于其所在像素单元中第二子像素14中心和与之相邻的另一像素单元中的第二子像素14的中心连线的延长线的外侧。例如，具体到一些实施例中，如图7及图8，第一像素单元中的第二子像素R1的中心和与第一像素单元相邻的第二像素单元中的第二子像素R2的中心的连线的延长线，与第一像素单元中的第三子像素G11的中心和第四子像素G12的中心错开，且第三子像素G11的中心和第四子像素G12的中心位于前述的连线的延长线的两侧。需要说明的是，子像素的中心位于中心连线的外侧是指，子像素的中心与中心连线错开，例如，子像素的中心位于中心连线的一侧。
同一像素单元中，沿第一方向和第二方向，相邻的两个子像素之间的最小距离为p，沿第一方向和第二方向，相邻的两个像素单元中最相邻的不同颜色的子像素之间的最小距离也为n。其中，10um<n<30um。如此，一方面，使子像素的排布更为均匀，有利于提高显示质量，另一方面，可以有效的避免相邻子像素之间的发光串色或干扰产生锯齿感。需要说明的是，本申请实施例提供的显示面板，可以为有机发光显示面板，子像素至少包括阳极和阴极，以及位于阳极和阴极之间的发光层，驱动电路向阳极和阴极之间施加电压，激发载流子迁移，作用于发光层，从而发射出光线。显示面板还可以包括像素定义层，像素定义层界定出了多个像素开口，子像素的发光层设于像素开口中，以避免相邻的子像素之间发生串色或干扰。因此，像素开口的面积即为子像素的发光面积，但是，受限于蒸镀技术，为保证发光材料完全蒸镀于像素开口内，通常，掩膜板的开口面积大于像素开口的面积，以留有蒸镀余量。例如，如图7所示，子像素的内侧边称为像素边，即是像素定义层(PDL层)的像素开口的边界，外侧边称为子像素的虚拟边，所述虚拟边是指Mask(掩膜板)的蒸镀开口的边界。故，本申请的实施例中，子像素之间的间距是指两个子像素的像素边之间的距离。而具体到如图3及图7所示的实施例中，相邻的两个子像素之间具有彼此相邻且平行的两条像素边，则相邻的两个子像素之间最小距离为该彼此相邻且平行的 两条像素边之间的垂线距离。
进一步地，第一像素单元中的第二子像素R1与沿第二方向相邻排布的第二像素单元的第三子像素G21之间的最小距离为p，n<p<3n。或者第二像素单元中的第二子像素R2与沿第一方向相邻排布的第一像素单元的第三子像素G11之间的最小距离为q，n<q<3n。如此，可以保证透光预留区拥有足够大小，进而满足屏下感光器件的正常工作所需要的进光量。
相邻四个第三子像素和第四子像素的中心连线形成虚拟四边形，该虚拟四边形的最小内角γ大于60°，小于90°。如此，一方面，通过控制最小角度限制相邻的四个第三子像素和第四子像素的距离，避免距离过大而导致显示不均。另一方面，也使相邻像素组中的绿色的子像素不易太近，进一步地避免因相邻的绿色的子像素距离较近而导致的相邻的两个绿色的子像素难以分辨，被人眼视觉上合二为一的情况。
位于同一行和/或列的第三子像素的中心连线为非直线或近似直线；和/或同一行和/或列的第四子像素的中心连线为非直线或近似直线。例如，如图6所示，位于同一行和/或列的绿色的子像素的中心连线呈锯齿状。如此，一方面，弱化了子像素的凸出程度，改善了彩边现象，另一方面，使相邻像素组中的绿色的子像素不易太近，进一步地避免因相邻的绿色的子像素距离较近而导致的相邻的两个绿色的子像素难以分辨，被人眼视觉上合二为一的情况。
在第一方向和第二方向上，红色的子像素的中心不在一条直线上；或在第一方向和第二方向上，绿色的子像素的中心不在一条直线上；或在第一方向和第二方向上，蓝色的子像素的中心不在一条直线上。如此，保证了子像素之间的错位排布，有效地改善了彩边现象。
可以理解，在一些实施例中，同一行和/列的第一子像像素的中心连线可以直线，同一行和/列的第二子像素的中心连线可以为直线，在此不作限定。
奇数行或列的任一像素组中两个绿色的子像素，与相邻偶数行或列的像素组中最相邻的两个绿色的子像素的中心连线形成第五虚拟四边形；第五虚拟四边形中的最小内角γ≥60°。如此，进一步地避免因相邻的绿色的子像素距离较近而导致的相邻的两个绿色的子像素难以分辨，被人眼视觉上合二为一的情况。

基于同样的申请构思，本申请还提供一种掩膜板，用于制作本申请实施例提供的像素排布结构，该掩膜板包括多个开口区域，所述开口区域与第一子像素12、第二子像素14、第三子像素16a或第四子像素16b的形状和位置相对应。
基于同样的申请构思，本申请还提供一种显示装置，该显示装置包括上述各个方面中的实施例中的显示面板100。
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。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
