具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开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。“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。
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，从而会导致显示装置的制作工艺的难度和制作成本的增加。另一方面，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数，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。然而，采用子像素渲染(SPR)技术的像素排列结构会对显示品质产生一些不利影响，例如，显示画面有颗粒感、波动感，显示画面中的线条不连续等。
图1A为一种阵列基板的示意图；图1B为一种阵列基板中一个子像素列的示意图。如图1A所示，该阵列基板10包括第一子像素11、第二子像素12和第三子像素13。第一子像素11发出的光的颜色可为人眼敏感的颜色，也就是说，人眼在进行视觉合成的时候，第一子像素11发出的光的颜色所占的比重更高。如图1B所示，在第一子像素11沿第一方向形成的子像素行20中，相邻的第一子像素11在第二方向上的位置差异较大，即相邻的第一子像素11的中心在第二方向上距离较大；因此，在该阵列基板用于直线时，人眼视觉中的直线的“波动感”获“锯齿感”较强，使得显示画面的品质降低。
对此，本公开实施例提供一种阵列基板和显示装置。该阵列基板包括多个像素组，各像素组包括一个第一子像素、一个第二子像素、一个第三子像素和一个第四子像素；在各像素组中，第一子像素的中心和第二子像素的中心的第一连线与第三子像素的中心和第四子像素的中心的第二连线相交；多个像素组沿第一方向排列形成N个像素组行，N个像素组行在第二方向上排列，相邻的两个像素组行在第一方向上错位设置；第i个像素组行中的多个第一子像素和第i+1个像素组行中的多个第二子像素在第一方向上交替排列，以形成子像素行，在一个子像素行中，相邻的第一子像素中心和第二子像素的中心的连线与第一方向的夹角小于20度，N为大于等于3的正整数，i为大于等于1，小于等于N的正整数。在该阵列基板中，第一子像素和第二子像素可为发出同一颜色的光的子像素，并且该颜色可为人眼敏感的子像素。由于该子像素行中相邻的第一子像素中心和第二子像素的中心的连线与第一方向的夹角小于20度，因此该子像素行的波动感更小，人眼视觉上更接近一条直线，从而可减轻甚至消除显示画面的“波动感”或“锯齿感”，并使得显示画面的线条更加连续，自然。
下面，结合附图对本公开实施例提供的阵列基板和显示装置进行详细的说明。
本公开一实施例提供一种阵列基板。图2A为本公开一实施例提供的一种阵列基板的示意图。图2B为本公开一实施例提供的一种阵列基板中一个子像素行的显示效果示意图。
如图2A和2B所示，该阵列基板100包括多个第一子像素行310和多个第二子像素行320；各第一子像素行310包括在第一方向上交替排列的多个第一子像素121和多个第二子像素122；各第二子像素行320包括在第一方向上交替排列的多个第三子像素123和多个第四子像素124；多个第一子像素行310和多个第二子像素行320沿第二方向交替排列。第二方向与第一方向相交，例如，第二方向与第一方向相互垂直。需要说明的是，上述的“第二方向与第一方向相互垂直”包括第一方向和第二方向严格相互垂直，即第一方向和第二方向之间的夹角为90度的情况，也包括第一方向和第二方向大致相互垂直，即第一方向和第二方向之间的夹角在80-100度的范围的情况。
如图2A和2B所示，在第一子像素行310中，相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角小于20度。
在本公开实施例提供的阵列基板中，第一子像素121和第二子像素122可为发同样颜色光的子像素，并且该颜色可为人眼敏感的子像素。由于该第一子像素行310中相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ小于20度，因此该第一子像素行310的波动感更小，在人眼视觉中更接近一条直线，从而可减轻甚至消除显示画面的“波动感”或“锯齿感”，并使得显示画面的线条更加连续，自然。
在一些示例中，如图2A所示，该阵列基板100包括衬底基板110和位于衬底基板110上的多个像素组120；各像素组120包括一个第一子像素121、一个第二子像素122、一个第三子像素123和一个第四子像素124。在各像素组120中，第一子像素121的中心和第二子像素122的中心的第一连线CL1与第三子像素123的中心和第四子像素124的中心的第二连线CL2相交。需要说明的是，在该像素组120中，第一子像素121和第二子像素122可为发同样颜色光的子像素；另外，第一子像素121和第二子像素122的形状也可相同，第一子像素121和第二子像素122之间的区别在于它们的位置不同。另外，上述的“中心”是指子像素有效发光区域的亮度中心或者几何中心。
如图2A所示，多个像素组120沿第一方向排列形成N个像素组行210；N个像素组行210在第二方向上排列，相邻的两个像素组行210在第一方向上错位设置，也就是说，相邻的两个像素组行210中同样序数的像素组在沿第一方向上延伸的参考直线上的正投影的中心不重叠。因此，相邻的两个像素组行210在第二方向上可以设置的更近，更紧密，从而可提高像素密度或分辨率。
如图2A和图2B所示，第i个像素组行210中的多个第一子像素121和第i+1个像素组行210中的多个第二子像素122在第一方向上交替排列，以形成上述第一子像素行310；并且，在一个第一子像素行310中，相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ小于20度，N为大于等于3的正整数，i为大于等于1，小于等于N的正整数。
在本公开实施例提供的阵列基板中，第一子像素121和第二子像素122可为发同样颜色光的子像素，并且该颜色可为人眼敏感的子像素。由于该第一子像素行310中相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ小于20度，因此该第一子像素行310的波动感更小，在人眼视觉中更接近一条直线，从而可减轻甚至消除显示画面的“波动感”或“锯齿感”，并使得显示画面的线条更加连续，自然。
另外，在一个像素组120中，可采用子像素渲染(Sup-Pixel Rendering，SPR)技术使得第一子像素121和第二子像素122分别借用第三子像素123和第四子像素124，以模拟形成两个像素，从而可提高像素分辨率，并降低制作工艺的难度和制作成本。
例如，第i个所述像素组行210中的多个第三子像素123和多个第四子像素124在第一方向上交替排列，以形成一个第二子像素行320。
在一些示例中，第一子像素被配置为发第一颜色的光，第二子像素被配置为发第二颜色的光，第一颜色和第二颜色相同。例如，第一子像素121和第二子像素122被配置为发绿光，即第一颜色和第二颜色均为绿色。需要说明的是，绿光为人眼敏感的光，因此在人眼视觉中，像素的亮度中心会靠近绿色子像素的亮度中心。
在一些示例中，第三子像素被配置为发第三颜色的光，第四子像素被配置为发第四颜色的光，第三颜色、第四颜色和第一颜色互不相同，第三子像素的发光效率大于第四子像素的发光效率。例如，第一颜色和第二颜色为绿色，第三颜色为红色，第四颜色为蓝色。当然，本公开实施例包括但不限于此。
在一些示例中，如图2A所示，进一步地，在一个第一子像素行310中，相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ小于15度。由于该第一子像素行310中相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角小于15度，因此该第一子像素行310的波动感可以进一步减小，从而可进一步减轻甚至消除显示画面的“波动感”或“锯齿感”。
在一些示例中，如图2A所示，在一个第一子像素行310中，相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ的范围在9-11度，例如10度。由此，该阵列基板可通过改变第三子像素和第四子像素的长宽比来使得连线CL与第一方向的夹角更小，从而进一步减轻甚至消除显示画面的“波动感”或“锯齿感”。
在一些示例中，如图2A和图2B所示，在第一子像素行310中相邻的第一子像素121和第二子像素122的朝向不同，即第一子像素121在衬底基板110上的正投影的形状旋转一定角度(例如180度)之后与第二子像素122在衬底基板110上的正投影的形状完全相同。
在一些示例中，如图2A和图2B所示，第一子像素121在衬底基板110上的正投影的形状包括第一突出部1211，第二子像素122在衬底基板110上的正投影的形状包括第二突出部1221，第一突出部1211和第二突出部1221的朝向相反。
在一些示例中，如图2A和图2B所示，第一子像素121在衬底基板110上的正投影的形状还包括与第一突出部1211相对设置的第一底边1212，第二子像素122在衬底基板110上的正投影的形状包括与第二突出部1221相对设置的第二底边1222，第一底边1212和第二底边1222不位于同一直线上。
在一些示例中，如图2A和图2B所示，在第一子像素行310中相邻的第一子像素121和第二子像素122靠近同一第二子像素行的边缘不平齐(例如图2A中的下边缘是不平齐的)。
在一些示例中，如图2A和图2B所示，在一个第一子像素行310中的多个第一子像素121和多个第二子像素122均与沿第一方向延伸的第一虚拟直线相交。也就是说，沿第一方向延伸的第一虚拟直线同时穿过在一个第一子像素行310中的多个第一子像素121和多个第二子像素122。由此，在一个第一子像素行中的多个第一子像素121和多个第二子像素 122在人眼视觉中更接近一条直线，从而可使得该第一子像素行310的波动感可以进一步减小，从而可进一步减轻甚至消除显示画面的“波动感”或“锯齿感”。
在一些示例中，如图2A和图2B所示，在一个第一子像素行310中的多个第一子像素121和多个第二子像素122在第一方向上均匀分布，从而可提高该阵列基板的显示品质。
在一些示例中，如图2A所示，在同一像素组行120之中，所有的第一子像素121的中心可位于同一直线上；所有的第二子像素121的中心可位于同一直线上；所有的第三子像素123的中心可位于同一直线上；所有的第四子像素124的中心可位于同一直线上。
在一些示例中，如图2A所示，在各像素组120中，第一子像素121和第三子像素123之间不设置其他子像素，第一子像素121和第四子像素124之间不设置其他子像素；同样的，第二子像素122和第三子像素123之间不设置其他子像素，第二子像素122和第四子像素124之间不设置其他子像素。
在一些示例中，如图2A所示，该阵列基板100还包括：子像素间隔170，设置在相邻的两个子像素之间，子像素可为上述的第一子像素121、第二子像素122、第三子像素123和第四子像素中的任意一种；各像素组120仅包括被子像素间隔170分隔开的四个子像素。
在一些示例中，如图2A所示，该阵列基板100还包括隔垫物250，隔垫物250可在该阵列基板的制作过程中用于支撑用于形成上述的第一子像素、第二子像素、第三子像素和第四子像素的掩膜板(例如，精细金属掩膜板)。隔垫物250位于第一子像素行310中相邻的第一子像121素和第二子像素122之间。
在本公开实施例提供的阵列基板中，由于第一子像素行310中相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ减小了，即相邻的第一子像素121和第二子像素122在第二方向上的距离减小了，因此第三子像素和第四子像素的长宽比降低，从而会在相邻的第一子像素121和第二子像素122之间留下空白区域。该阵列基板可利用该空白区域来设置隔垫物，从而可避免隔垫物在制作过程中与掩膜板的开口边缘发生摩擦而产生颗粒物(Particle)，进而可避免颗粒物对显示品质造成不利影响。
在一些示例中，如图2A所示，多个第二子像素行320的数量为K，隔垫物还位于第j个第二子像素行中的第三子像素和第j+1个第二子像素行中的第四子像素之间，或者，隔垫物还位于第j个第二子像素行中的第四子像素和第j+1个第二子像素行中的第三子像素之间，K为大于等于3的正整数，j为大于等于1，小于等于K的正整数。在一些示例中，如图2A所示，该阵列基板100包括多个隔垫物250，多个隔垫物250的中心连线可形成矩形网格或者菱形网格。
在一些示例中，如图2A所示，在第二子像素行320中所有的第三子像素123和第四子像素124的中心可位于沿第一方向延伸的虚拟直线上，从而可提高显示对称性。
图3A为本公开一实施例提供的一种阵列基板的局部示意图；图3B为本公开一实施例提供的一种阵列基板沿图3A中AB方向的剖面示意图。
在一些示例中，如图2A和图3A所示，第三子像素123在第二方向上的尺寸与第三子 像素123在第一方向上的尺寸之比小于3.5。由此，通过降低第三子像素123的长宽比，可使得第一子像素行310中相邻的第一子像素121的中心和第二子像素122的中心设置得更近，例如使得相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角小于15度。另一方面，通过将第三子像素123在第二方向上的尺寸与第三子像素123在第一方向上的尺寸之比设置为小于3.5，还可利于提高像素组的显示对称性。需要说明的是，上述的第三子像素的尺寸可为第三子像素的有效发光区的尺寸。
在一些示例中，如图2A和图3A所示，第三子像素123在第二方向上的尺寸与第三子像素123在第一方向上的尺寸之比小于2。由此，通过降低第三子像素123的长宽比，可使得第一子像素行310中相邻的第一子像素121的中心和第二子像素122的中心设置得更近，例如使得相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角小于15度。另一方面，通过将第三子像素123在第二方向上的尺寸与第三子像素123在第一方向上的尺寸之比设置为小于2，还可利于提高像素组的显示对称性。需要说明的是，上述的第三子像素的尺寸可为第三子像素的有效发光区的尺寸。
在一些示例中，如图2A和图3A所示，第三子像素123在第二方向上的尺寸与第三子像素123在第一方向上的尺寸之比小于1.2。由此，该阵列基板可进一步使得第一子像素行中相邻的第一子像素的中心和第二子像素的中心设置得更近，并且还可利于提高像素组的显示对称性。
在一些示例中，如图2A和图3A所示，第i个像素组行210中一个像素组120中的第一子像素121至少部分位于第i+1个像素组行210中两个相邻的像素组120之间，例如，位于相邻的第三子像素123和第四子像素124之间。也就是说，第i个像素组行210在沿第二方向延伸的参考直线上的正投影与第i+1个像素组行210在沿第二方向延伸的参考直线上的正投影部分交叠。由此，该阵列基板可将相邻的两个像素组行210设置得更紧密，从而可提高像素密度和开口率。
例如，如图2A和图3A所示，第i个像素组行210中一个像素组120中的第一子像素121在沿第二方向延伸的参考直线上的正投影与第i+1个像素组行210中两个相邻的像素组120在沿第二方向延伸的参考直线上的正投影至少部分重叠；第i个像素组行210中一个像素组120中的第一子像素121在沿第二方向延伸的参考直线上的正投影与第i+1个像素组行210中两个相邻的第三子像素123和第四子像素124在沿第二方向延伸的参考直线上的正投影至少部分重叠。
在一些示例中，如图2A和图3A所示，第i个像素组行210与第i+2个像素组行210在第一方向上对齐，第i个像素组行210中的一个第一子像素121和第i+2个像素组行210中的一个第二子像素122形成子像素对125，在子像素对125中，第一子像素121的中心与第二子像素122的中心的第三连线CL3与第二方向平行。由此，该阵列基板具有较好的显示品质。
在一些示例中，如图2A和图3A所示，子像素对125中的第一子像素121的有效发光 区和第二子像素122的有效发光区在第二方向上的最远距离大于第三子像素123在第二方向上的尺寸和第四子像素124在第二方向上的尺寸。
在一些示例中，如图3B所示，该阵列基板100还包括位于衬底基板110上的第一颜色像素电极141、第二颜色像素电极142、第三颜色像素电极143和第四颜色像素电极144；位于第一颜色像素电极141、第二颜色像素电极142、第三颜色像素电极143和第四颜色像素电极144远离衬底基板110的一侧的像素限定层150；以及位于像素限定层150远离衬底基板110的一侧的第一颜色发光层161、第二颜色发光层162、第三颜色发光层163和第四颜色发光层164。像素限定层150包括第一开口151、第二开口152、第三开口153和第四开口154，第一开口151暴露第一颜色像素电极141，第二开口152暴露第二颜色像素电极142，第三开口153暴露第三颜色像素电极143，第四开口154暴露第四颜色像素电极144；第一颜色发光层161通过第一开口151与第一颜色像素电极141被第一开口151暴露的部分接触设置；第二颜色发光层162通过第二开口152与第二颜色像素电极142被第二开口152暴露的部分接触设置；第三颜色发光层163通过第三开口153与第三颜色像素电极143被第三开口153暴露的部分接触设置；第四颜色发光层164通过第四开口154与第四颜色像素电极144被第四开口154暴露的部分接触设置。此时，第一子像素121的有效发光区的形状和尺寸被第一开口151限定，第二子像素122的有效发光区的形状和尺寸被第二开口152限定，第三子像素123的有效发光区的形状和尺寸被第三开口153限定，第四子像素124的有效发光区的形状和尺寸被第四开口154限定。
例如，第一颜色像素电极141被配置为驱动第一颜色发光层161发第一颜色的光；第二颜色像素电极142被配置为驱动第二颜色发光层162发第二颜色的光；第三颜色像素电极143被配置为驱动第三颜色发光层163发第三颜色的光；第四颜色像素电极144被配置为驱动第四颜色发光层164发第四颜色的光。
例如，第一颜色和第二颜色均为绿色，第三颜色为红色，第四颜色为蓝色。当然，本公开实施例包括但不限于此。
在一些示例中，如图3A所示，子像素对125中的第一子像素121的第一颜色发光层161和第二子像素122的第二颜色发光层162集成为同一发光层。也就是说，子像素对125中的第一子像素121的第一颜色发光层161和第二子像素122的第二颜色发光层162可通过同一精细掩模板(FMM)的同一开口形成。
例如，如图3A所示，第一子像素121和第二子像素122可被配置为发相同颜色的光。然而，由于同一像素组120中的第三子像素123与第四子像素124的距离较近，因此同一像素组120中的第一子像素121的第一颜色发光层161和第二子像素122的第二颜色发光层162可不集成在一起。相反，125中的第一子像素121的第一颜色发光层161和第二子像素122的第二颜色发光层162可集成为同一发光层。
在一些示例中，如图3A和图3B所示，第一子像素121可包括上述的第一颜色像素电极141以及设置在第一颜色像素电极141上的第一颜色发光层161；第二子像素122包括第 二颜色像素电极142以及设置在第二颜色像素电极142上的第二颜色发光层162；第三子像素123包括第三颜色像素电极143以及设置在第三颜色像素电极143上的第三颜色发光层163；第四子像素124包括第四颜色像素电极144以及设置在第四颜色像素电极144上的第四颜色发光层164。需要说明的是，上述的各个发光层可仅包括直接进行发光的发光层，也可包括电子传输层、电子注入层、空穴传输层、空穴注入层等辅助功能膜层。
需要说明的是，上述的第一子像素、第二子像素、第三子像素和第四子像素的形状和尺寸可为第一子像素、第二子像素、第三子像素和第四子像素的有效发光区域的形状和尺寸，其可以被上述的第一过孔、第二过孔、第三过孔和第四过孔限定。因此，第一颜色像素电极、第二颜色像素电极、第三颜色像素电极和第四颜色像素电极的形状可与上述的第一子像素、第二子像素、第三子像素和第四子像素的形状不同。当然，本公开实施例包括但不限于此，第一颜色像素电极、第二颜色像素电极、第三颜色像素电极和第四颜色像素电极的形状也可与上述的第一子像素、第二子像素、第三子像素和第四子像素的形状相同。
另一方面，第一颜色发光层、第二颜色发光层、第三颜色发光层和第四颜色发光层的具体形状可根据制备工艺进行设置，本公开实施例在此不作限制。例如，第一颜色发光层的形状可由制备工艺中的掩模板开孔的形状决定。
在一些示例中，如图3B所示，第一颜色像素电极141的尺寸大于第一开口151的尺寸，第二颜色像素电极142的尺寸大于第二开口152的尺寸，第三颜色像素电极143的尺寸大于第三开口153的尺寸，第四颜色像素电极144的尺寸大于第四开口154的尺寸。并且，第一颜色像素电极141超出第一开口151的距离、第二颜色像素电极142超出第二开口152的距离、第三颜色像素电极143超出第三开口153的距离大致相等和第四颜色像素电极144超出第四开口154的距离大致相等。也就是说，第一颜色像素电极141的边缘与第一开口151的边缘的最短距离、第二颜色像素电极142的边缘与第二开口152的边缘的最短距离、第三颜色像素电极143的边缘和第三开口153的边缘的最短距离和第四颜色像素电极144的边缘和第四开口154的边缘的最短距离大致相等。
图4为本公开一实施例提供的另一种阵列基板的示意图；图5为本公开一实施例提供的另一种阵列基板的示意图。
在一些示例中，如图4和图5所示，第一子像素121的有效发光区的形状和第二子像素122的有效发光区的形状可均为对称多边形，当然，本公开实施例包括但不限于此。
在一些实例中，如图4和图5所示，第三子像素123的有效发光区形状和第四子像素124的有效发光区的形状可为非中心对称多边形，从而可充分地利用阵列基板的面积，从而提高开口率。
例如，上述的第一子像素121的有效发光区的形状、第二子像素122的有效发光区的形状和第三子像素123的有效发光区的形状中的每个的边的数量大于5。
在一些示例中，如图4所示，第三子像素123的有效发光区的形状包括第一平行边组410，第一平行边组410包括沿第二方向延伸的第一平行边411和第二平行边412；在一个 像素组120中，第一平行边411位于第二平行边412远离第四子像素124的一侧，第一平行边411的长度大于第二平行边412的长度。在一个像素组120中，第一子像素121和第二子像素122的中心连线CL1位于第三子像素123的中心和第四子像素124的中心之间，因此第三子像素123的有效发光区和第四子像素124的有效发光区远离中心连线CL1的一侧具有较大的空间。因此，通过将第一平行边的长度设置为大于第二平行边的长度，一方面可增加第三子像素的有效发光区的面积，另一方面可提高空间利用率和开口率。需要说明的是，上述的开口率可为阵列基板中各个子像素的有效发光区的面积之和与阵列基板的面积的比值。
在一些示例中，如图4和图5所示，第四子像素124的有效发光区的形状包括第二平行边组420，第二平行边组420包括沿第二方向延伸的第三平行边421和第四平行边422；在一个像素组120中，第三平行边421位于第四平行边422远离第三子像素123的一侧，第三平行边421的长度大于第四平行边422的长度。在一个像素组120中，第一子像素121和第二子像素122的中心连线CL1位于第三子像素123的中心和第四子像素124的中心之间，因此第三子像素123的有效发光区和第四子像素124的有效发光区远离中心连线CL1的一侧具有较大的空间。因此，通过将第三平行边的长度大于第四平行边的长度，一方面可增加第四子像素的有效发光区的面积，另一方面可提高空间利用率和开口率。
值得注意的是，在采用精细金属掩膜(Fine Metal Mask，FMM)制作上述的阵列基板时，上述的第一平行边、第二平行边、第三平行边和第四平行边的延伸方向相同，并且该延伸方向可为精细金属掩膜(FMM)的拉伸方向，从而可有利于精细金属掩膜(FMM)张网力的传递，进而可提高产品良率。
在一些示例中，如图4所示，第三子像素123的有效发光区的形状包括在第二方向上距离最大的第一顶点P1和第二顶点P2，第三子像素123的有效发光区的形状被第一顶点P1和第二顶点P2的连线划分为第一部分1231和第二部分1232；在一个像素组120中，第一部分1231位于第二部分1232远离第四子像素124的一侧，第一部分1231在第二方向上的平均尺寸大于第二部分1232在第二方向上的平均尺寸。在一个像素组120中，第一子像素121和第二子像素122的中心连线CL1位于第三子像素123的中心和第四子像素124的中心之间，因此第三子像素123的有效发光区和第四子像素124的有效发光区远离中心连线CL1的一侧具有较大的空间。因此，通过将第一部分在第二方向上的尺寸设置为大于第二部分在第二方向上的尺寸，一方面可增加第三子像素的有效发光区的面积，另一方面可提高空间利用率和开口率。需要说明的是，上述的“平均尺寸”可为第一部分或第二部分在第二方向上加权平均尺寸。
在一些示例中，如图4和图5所示，第四子像素124的有效发光区的形状包括在第二方向上距离最大的第三顶点P3和第四顶点P4，第四子像素124的有效发光区的形状被第三顶点P3和第四顶点P4的连线划分为第三部分1243和第四部分1244；在一个像素组120中，第三部分1243位于第四部分1244远离第三子像素123的一侧，第三部分1243在第二 方向上的平均尺寸大于第四部分1244在第二方向上的平均尺寸。在一个像素组120中，第一子像素121和第二子像素122的中心连线CL1位于第三子像素123的中心和第四子像素124的中心之间，因此第三子像素123的有效发光区和第四子像素124的有效发光区远离中心连线CL1的一侧具有较大的空间。因此，通过将第三部分在第二方向上的尺寸设置为大于第四部分在第二方向上的尺寸，一方面可增加第四子像素的有效发光区的面积，另一方面可提高空间利用率和开口率。
在一些示例中，如图5所示，由于第四子像素124的发光效率降低，寿命也较低，因此可仅将第四子像素124的有效发光区向外扩展，以增加第四子像素的有效发光区的面积。此时，第三子像素123的有效发光区仍然可采用对称的形状。
在一些示例中，第三子像素123的发光效率大于第四子像素124的发光效率，此时第四子像素124的有效发光区的面积大于第三子像素123的有效发光区的面积。由于发光器件结构设计和材料体系的不同，发不同颜色的光的子像素的寿命存在差异。因此，通过将第四子像素的有效发光区的面积设置为大于第三子像素的有效发光区的面积，可以平衡上述的寿命差异，提高阵列基板的整体寿命。
在一些示例中，如图4和图5所示，第i个像素组行210中的第三子像素123的有效发光区与第i+1个像素组行210中的第四子像素124的有效发光区的最短距离D1小于同一像素组120中第一子像素121的有效发光区与第三子像素123的有效发光区的最短距离的2倍。在通常的阵列基板中，第i个像素组行中的第三子像素的有效发光区与第i+1个像素组行中的第四子像素的有效发光区的最短距离较大，该示例提供的阵列基板通过将上述的最短距离D1设置为小于同一像素组中第一子像素的有效发光区与第三子像素的有效发光区的最短距离的2倍，从而可增大第三子像素的面积，并提高开口率。
在一些示例中，如图4和图5所示，第i个像素组行210中的第三子像素123的有效发光区与第i+1个像素组行210中的第四子像素124的有效发光区的最短距离D1小于同一像素组120中第一子像素121的有效发光区与第三子像素123的有效发光区的最短距离的1.5倍。由此，该阵列基板可进一步增加第三子像素的面积，并提高开口率。
在一些示例中，如图5所示，第i个像素组行210中的第四子像素124的有效发光区与第i+1个像素组行210中的第三子像素123的有效发光区的最短距离D2小于同一像素组120中第一子像素121的有效发光区与第四子像素124的有效发光区的最短距离的2倍。在通常的阵列基板中，第i个像素组行中的第四子像素的有效发光区与第i+1个像素组行中的第三子像素的有效发光区的最短距离较大，该示例提供的阵列基板通过将上述的最短距离D2设置为小于同一像素组中第一子像素的有效发光区与第四子像素的有效发光区的最短距离的2倍，从而可增大第四子像素的面积，并提高开口率。
在一些示例中，如图5所示，第i个像素组行210中的第四子像素124的有效发光区与第i+1个像素组行210中的第三子像素123的有效发光区的最短距离D2小于同一像素组120中第一子像素121的有效发光区与第四子像素124的有效发光区的最短距离的1.5倍。由此， 该阵列基板可进一步增加第三子像素的面积，并提高开口率。
在一些示例中，如图5所示，第四子像素124的有效发光区的边缘可包括曲线。
在一些示例中，如图4和图5所示，第i个像素组行210中一个像素组120中的第一子像素121至少部分位于第i+1个像素组行210中两个相邻的像素组120之间，例如，位于相邻的第三子像素123和第四子像素124之间。由此，该阵列基板可将相邻的两个像素组行210设置得更紧密，从而可提高像素密度和开口率。
图6为本公开一实施例提供的另一种阵列基板的示意图；图7为本公开一实施例提供的另一种阵列基板的示意图。
如图6和图7所示，该阵列基板100包括衬底基板110和位于衬底基板110上的多个像素组120；各像素组120包括一个第一子像素121、一个第二子像素122、一个第三子像素123和一个第四子像素124。在各像素组120中，第一子像素121的中心和第二子像素122的中心的第一连线CL1与第三子像素123的中心和第四子像素124的中心的第二连线CL2相交。需要说明的是，在该像素组120中，第一子像素121和第二子像素122可为发同样颜色光的子像素；另外，第一子像素121和第二子像素122的形状也可相同，第一子像素121和第二子像素122之间的区别在于它们的位置不同。另外，上述的“中心”是指子像素有效发光区域的亮度中心或者几何中心。
如图6和图7所示，多个像素组120沿第一方向排列形成N个像素组行210；N个像素组行210在第二方向上排列，相邻的两个像素组行210在第一方向上错位设置，也就是说，相邻的两个像素组行210中同样序数的像素组在沿第一方向上延伸的参考直线上的正投影的中心不重叠。因此，相邻的两个像素组行210在第二方向上可以设置的更近，更紧密，从而可提高像素密度或分辨率。
如图6和图7所示，第i个像素组行210中的多个第一子像素121和第i+1个像素组行210中的多个第二子像素122在第一方向上交替排列，以形成第一子像素行310；并且，在一个第一子像素行310中，相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ小于等于10度，N为大于等于3的正整数，i为大于等于1，小于等于N的正整数。
在本公开实施例提供的阵列基板中，第一子像素121和第二子像素122可为发同样颜色光的子像素，并且该颜色可为人眼敏感的子像素。由于该第一子像素行310中相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ小于等于10度，因此该第一子像素行310的波动感更小，在人眼视觉中更接近一条直线，从而可减轻甚至消除显示画面的“波动感”或“锯齿感”，并使得显示画面的线条更加连续，自然。
例如，在一个第一子像素行310中，相邻的第一子像素121的中心和第二子像素122的中心的连线CL与第一方向的夹角θ等于0度；也就是说，在一个第一子像素行310中所有的第一子像素121的中心和第二子像素122的中心可位于同一直线上，且该直线平行于第一方向。因此，该阵列基板可消除该第一子像素行310的波动感，从而消除显示画面的 “波动感”或“锯齿感”。
在一些示例中，如图6和图7所示，第一子像素行310可在第二方向上均匀排布，也就是说，任意两个相邻的第一子像素行310之间的距离相等，从而进一步提高该阵列基板的像素排布的均匀度和对称性，从而可进一步提高显示品质。
在一些示例中，如图7所示，由于第四子像素124的发光效率降低，寿命也较低，因此可将第四子像素124的有效发光区向外扩展，以增加第四子像素的有效发光区的面积。
例如，如图7所示，第四子像素124的有效发光区的形状包括第二平行边组420，第二平行边组420包括沿第二方向延伸的第三平行边421和第四平行边422；在一个像素组120中，第三平行边421位于第四平行边422远离第三子像素123的一侧，第三平行边421的长度大于第四平行边422的长度。在一个像素组120中，第一子像素121和第二子像素122的中心连线CL1位于第三子像素123的中心和第四子像素124的中心之间，因此第三子像素123的有效发光区和第四子像素124的有效发光区远离中心连线CL1的一侧具有较大的空间。因此，通过将第三平行边的长度大于第四平行边的长度，一方面可增加第四子像素的有效发光区的面积，另一方面可提高空间利用率和开口率。
在一些示例中，第三子像素123的发光效率大于第四子像素124的发光效率，此时第四子像素124的有效发光区的面积大于第三子像素123的有效发光区的面积。由于发光器件结构设计和材料体系的不同，发不同颜色的光的子像素的寿命存在差异。因此，通过将第四子像素的有效发光区的面积设置为大于第三子像素的有效发光区的面积，可以平衡上述的寿命差异，提高阵列基板的整体寿命。
本公开至少一个实施例还提供一种显示装置。图8为本公开一实施例提供的一种显示装置的示意图。如图8所示，该显示装置500包括上述的阵列基板100。由于该阵列基板通过将第一子像素行中相邻的第一子像素中心和第二子像素的中心的连线与第一方向的夹角小于20度，可该第一子像素行的波动感更小，人眼视觉上更接近一条直线，从而可减轻甚至消除显示画面的“波动感”或“锯齿感”，因此该显示装置可在具有较高分辨率的同时，具有较高的显示品质。
例如，在一些示例中，该显示装置可以为智能手机、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。
有以下几点需要说明：
(1)本公开实施例附图中，只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计。
(2)在不冲突的情况下，本公开同一实施例及不同实施例中的特征可以相互组合。
以上，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以权利要求的保护范围为准。
