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。并且在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。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。
需要注意的是，附图中各图形的尺寸和形状不反映真实比例，目的只是示意说明本公开内容。并且自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。
通常，为了降低OLED显示面板的内部结构对环境光线的反射率，通常采用以下两种方式：第一种方式，在OLED显示面板的出光侧贴附圆偏光片，该圆偏光片能够减少进入OLED显示面板内的环境光被OLED显示面板的内部结构反射后从出光面的出射量。第二种方式，在OLED显示面板的封装层上设置彩色光阻层+黑矩阵，即封装层上彩膜(Color Filter on Encapsulation，COE)结构+黑矩阵，由于该彩色光阻层能够对光线起到过滤作用，因此也可以减少进入OLED显示面板内的环境光被OLED显示面板的内部结构反射后从出光面的出射量。此外，彩色光阻层与圆偏光片相比，彩色光阻层对OLED显示面板所发出的光线的透过率更高，且集成了彩色光阻层的OLED显示面板的厚度更低，因此OLED显示面板采用COE结构+黑矩阵是发展趋势。
然而，在集成了彩色光阻层的OLED显示面板中，不同视角下不同颜色OLED所发出的光线的衰减速率不一致，导致不同视角下显示面板在画面显示时会发生色偏的现象。例如，在OLED显示面板在显示白色画面时，可能会出现发青或发粉等现象。如此，显示面板的显示效果较差。
示例性地，显示面板可以包括多个不同颜色的发光器件。这些不同颜色的发光器件可以包括：发红光的红色发光器件、发绿光的绿色发光器件以及发蓝光的蓝色发光器件，这样可以通过红绿蓝三原色光进行混色，以实现彩色显示。在实际应用中，由于发光器件的微腔结构的影响，不同视角下不同颜色的发光器件的亮度衰减速率不一致。因此，不同视角下显示面板在显示白画面时会发生色偏的现象。具体地，如图1至图3所示，图1为相关技术 中显示面板采用红绿蓝发光器件基于三原色光混合白光时的W视角CIE(Commission Internationale d'Eclairage)轨迹图。图2为相关技术中红色发光器件、绿色发光器件以及蓝色发光器件的单色视角亮度衰减图，图3为相关技术中显示面板采用红绿蓝发光器件基于三原色光混合白光时的W视角色偏和W视角亮度衰减比例的具体参数对比示意图。其中，LR10代表红色发光器件的单色视角亮度衰减曲线，LG10代表绿色发光器件的单色视角亮度衰减曲线，LB10代表蓝色发光器件的单色视角亮度衰减曲线。由图1至图3可以看出，不同视角下不同颜色的发光器件的亮度衰减速率不一致，其中，红色发光器件的亮度衰减较慢，绿色发光器件的亮度衰减较快，在采用红绿蓝发光器件基于三原色光混合白光时，不同视角下显示面板在画面显示时会发生色偏的现象。
有鉴于此，本公开实施例提供的显示面板，如图4至图7所示，包括：衬底基板100以及位于衬底基板100上的像素限定层170。其中，衬底基板100包括多个像素(如spx1～spx3)，像素限定层170具有多个像素开口(如KK1～KK3)，多个像素和多个像素开口一一对应。即一个像素包括一个像素开口。并且，多个像素包括第一颜色像素spx1和第二颜色像素spx2；其中，第一颜色像素spx1的像素开口在单位面积中视角亮度的衰减速率为第一衰减速率，第二颜色像素spx2的像素开口在单位面积中视角亮度的衰减速率为第二衰减速率，第一衰减速率小于第二衰减速率。以及，一个第一颜色像素spx1的像素开口的面积小于一个第二颜色像素spx2的像素开口的面积。即将第一颜色像素spx1的视角亮度的衰减速率在原来较慢的基础上进行提高，从而提高第一颜色像素spx1的视角亮度衰减的衰减速率。以及将第二颜色像素spx2的视角亮度的衰减速率由原来较快的基础上进行降低，从而降低第二颜色像素spx2的视角亮度的衰减速率，进而使第一颜色像素spx1和第二颜色像素spx2的衰减速率差异降低。这样可以平衡不同出光颜色像素开口处的亮度衰减达到大致平衡，改善W视角色偏问题。
在本公开一些实施例中，如图4至图7所示，多个像素还包括第三颜色 像素spx3；一个第一颜色像素spx1、一个第二颜色像素spx2、一个第三颜色像素spx3组成一个重复单元。重复单元内，第一颜色像素spx1和第二颜色像素spx2沿第一方向F1排布，且过第三颜色像素spx3的像素开口中心且垂直于第一方向F1的直线位于第一颜色像素spx1的像素开口与第二颜色像素spx2的像素开口之间的间隙处。多个重复单元沿第一方向F1依次排布，组成像素行。以及，多个像素行沿第二方向F2依次排布。示例性地，第一方向F1和第二方向F2交叉设置。例如，第一方向F1和第二方向F2垂直设置。可选地，第一方向F1为像素的行方向，第二方向F2为像素的列方向。
在本公开一些实施例中，衬底基板与像素限定层之间设置有像素电路阵列层。像素电路阵列层包括多个像素电路。每个像素开口一一设置一个发光器件。每一个像素中设置一个像素电路和一个发光器件，且像素电路与发光器件耦接，以通过像素电路向发光器件的阳极输入驱动电流，驱动发光器件发光。
示例性地，衬底基板上设置的多个像素可以包括红色像素，绿色像素以及蓝色像素，这样可以通过红绿蓝进行混色，以实现彩色显示。并且，一个像素包括一个像素开口，则每一个像素开口出射对应颜色的光。具体地，红色像素包括的像素开口设置发红光的红色发光器件，绿色像素包括的像素开口设置发绿光的绿色发光器件，蓝色像素包括的像素开口设置发蓝光的蓝色发光器件。可选地，发光器件可以为OLED、QLED(Quantum Dot Light Emitting Diodes，量子点发光二极管)中的至少一种。
示例性地，如图4所示，第一颜色像素spx1可以为红色像素，则第一颜色像素spx1中设置红色发光器件。第二颜色像素spx2可以为绿色像素，则第二颜色像素spx2中设置绿色发光器件。第三颜色像素spx3可以为蓝色像素，则第三颜色像素spx3中设置蓝色发光器件。当然，在实际应用中，也可以采用其他颜色来实现彩色显示，则第一颜色像素spx1、第二颜色像素spx2以及第三颜色像素spx3还可以为其他颜色的像素，并且，第一颜色像素spx1、第二颜色像素spx2以及第三颜色像素spx3具体为哪种颜色的像素，可以根据实 际应用的需求进行确定，在此不作限定。
示例性地，如图8所示，发光器件可以包括依次层叠设置的阳极210、空穴注入层220、第一空穴传输层230、第二空穴传输层240、发光层250、空穴阻挡层260、电子传输层270、电子注入层280和阴极290。空穴注入层220、第一空穴传输层230、电子阻挡层、空穴阻挡层260、电子传输层270、电子注入层280可以进一步提升显示面板的性能。本公开对空穴注入层220、第一空穴传输层230、电子阻挡层、空穴阻挡层260、电子传输层270、电子注入层280的具体材料不作限制，本领域技术人员可以根据使用需求进行选择和调整，例如，形成电子注入层280的材料可以是Yb。
在本公开一些实施例中，第二空穴传输层240包括多个第二子空穴传输层，每一个发光器件包括一个第二子空穴传输层。不同发光器件中的第二子空穴传输层相互独立设置。示例性地，如图9a所示，红色发光器件包括阳极211、第二子空穴传输层241以及发光层251，且第二子空穴传输层241位于第一空穴传输层230和发光层251之间。绿色发光器件包括阳极212、第二子空穴传输层242以及发光层252，且第二子空穴传输层242位于第一空穴传输层230和发光层252之间。蓝色发光器件包括阳极213、第二子空穴传输层243以及发光层253，且第二子空穴传输层243位于第一空穴传输层230和发光层253之间。其中，第二子空穴传输层241的厚度d1大于第二子空穴传输层242的厚度d2大于第二子空穴传输层243的厚度d3。这样可以使红色发光器件的微腔的腔长大于绿色发光器件的微腔的腔长大于蓝色发光器件的微腔的腔长，从而实现的色域可达115％@NTSC1931。进一步地，如图9b所示，还可以将厚度d1增加Δd1(例如，Δd1可以为
Figure PCTCN2022102457-appb-000001
)，将厚度d2减少Δd2(例如，Δd2可以为
Figure PCTCN2022102457-appb-000002
)，从而实现的色域可达125％@NTSC1931。需要说明的是，虽然第二子空穴传输层241～243的厚度有差异，但是该厚度差异相对于显示面板中层状结构的厚度来说是很小的，并不会造成膜层的凹凸不平。
在本公开一些实施例中，如图6与图7所示，所述多个像素中的任一个 像素的像素开口，在所述衬底基板100的正投影为矩形。示例性地，第一颜色像素spx1的像素开口KK1在所述衬底基板100的正投影为长方形，第二颜色像素spx2的像素开口KK2在所述衬底基板100的正投影也为长方形，第三颜色像素spx3的像素开口KK3在所述衬底基板100的正投影也为长方形。并且，第一颜色像素spx1的像素开口KK1的长边、第二颜色像素spx2的像素开口KK2的长边、第三颜色像素spx3的像素开口KK3的长边均与第一方向F1平行。第一颜色像素spx1的像素开口KK1的短边、第二颜色像素spx2的像素开口KK2的短边、第三颜色像素spx3的像素开口KK3的短边均与第二方向F2平行。

需要说明的是，第一尺寸至第六尺寸也可以是上述像素开口的底端(即倒梯形的短边)至顶端(即倒梯形的长边)中同一位置处的尺寸，即上述像素开口的底端(即倒梯形的短边)至顶端(即倒梯形的长边)中同一位置处的尺寸也可以符合本公开实施例的参数设置。例如，第一尺寸至第六尺寸也可以是上述像素开口的顶端(即倒梯形的长边)位置处的尺寸，即上述像素开口的顶端(即倒梯形的长边)的尺寸也可以符合本公开实施例的参数设置。
在本公开一些实施例中，如图4与图5所示，显示面板还包括：封装层120、黑矩阵130以及彩色光阻层140。该封装层120位于像素限定层170背离衬底基板100一侧，黑矩阵130位于封装层120背离衬底基板100一侧，彩色光阻层140位于黑矩阵130背离衬底基板100一侧。示例性地，如图8所示，封装层120可以具有层叠设置的第一无机封装层121、有机封装层122以及第二无机封装层123。可选地，封装层120与阴极之间还设置有光耦合层181和LiF膜层182。并且，光耦合层181的折射率小于LiF膜层182和第一无机封装层121的折射率，这样可以使光耦合层181、LiF膜层182以及第一无机封装层121形成高低高折射率的组合，以提高光取出率。
需要说明的是，黑矩阵130以及彩色光阻层140也可以设置在第一无机封装层121和有机封装层122之间。或者，黑矩阵130以及彩色光阻层140也可以设置在有机封装层122与第二无机封装层123之间。在实际应用中，黑矩阵130以及彩色光阻层140的具***置，可以根据实际应用的需求进行确定，在此不作限定。
在本公开一些实施例中，如图4与图5所示，黑矩阵130具有多个黑矩阵开口，且多个黑矩阵开口与多个像素开口一一对应。以及，彩色光阻层140在衬底基板100的正投影覆盖多个黑矩阵开口在衬底基板100的正投影。可选地，彩色光阻层140具有多个不同颜色的光阻层140，对应红色像素的黑矩阵开口被红色光阻层140覆盖，对应绿色像素的黑矩阵开口被绿色光阻层140覆盖，对应蓝色像素的黑矩阵开口被蓝色光阻层140覆盖。
在本公开一些实施例中，如图4所示，每一个像素中，黑矩阵开口的截面也可以为大致的倒梯形，黑矩阵开口的底端(即倒梯形短边)在衬底基板100的正投影覆盖对应的像素开口的底端(即倒梯形短边)在衬底基板100的正投影。这样在垂直于衬底基板100所在平面上，可以使黑矩阵开口尽可能将对应的像素开口暴露出。需要说明的，在实际工艺中，黑矩阵的材料为有机材料，由于有机材料具有一定的流动性，因此实际制备出的黑矩阵的截面并不能完全为倒梯形的形状，而是类似倒梯形的形状。例如，基于工艺波动范围内，实际制备出的黑矩阵的截面的边角为圆弧形的倒梯形。
在本公开一些实施例中，第一颜色像素spx1中，黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK1的底端在衬底基板100的正投影的边缘具有第一开口间距。第二颜色像素spx2中，黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK2的底端在衬底基板100的正投影的边缘具有第二开口间距。其中，第一开口间距小于第二开口间距。示例性地，第一开口间距与第二开口间距之间的比值的范围为1:1.2～1:2.2。可选地，第一开口间距与第二开口间距之间的比值的范围为1:1.2、1:1.5、1:1.8、1:2.0、1:2.2中的一个。在实际应用中，可以根据实际应用的需求确定第一开口间距与第 二开口间距之间的比值的具体数值，在此不作限定。

示例性地，如图4与图6所示，第一颜色像素spx1中，在第二方向F2上，黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK1的底端在衬底基板100的正投影的边缘具有第一开口间距r22。第二颜色像素spx2中，在第二方向F2上，黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK2的底端在衬底基板100的正投影的边缘具有第二开口间距g22。其中，第一开口间距r22小于第二开口间距g22。示例性地，r22:g22为1:1.2～1:2.2。可选地，r22:g22为1:1.2、1:1.5、1:1.8、1:2.0、1:2.2中的一个。在实际应用中，可以根据实际应用的需求确定r22:g22的具体数值，在此不作限定。
进一步地，如图4与图6所示，第三颜色像素spx3中，黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口的底端在衬底基板100的正投影的边缘具有第三开口间距。其中，第三开口间距不小于第一开口间距，且第三开口间距小于第二开口间距。示例性地，第一开口间距与第三开口间距之间的比值的范围为1:1～1:1.2。可选地，第一开口间距、第二开口间距以及第三开口间距之间的比值的范围为1:1:1.2～1:1.2:2.2。可选地，第一开口间距、第二开口间距以及第三开口间距之间的比值的范围为1:1:1.2、1:1:1.5、1:1.2:1.8、1:1.2:2.0、1:1.2:2.2中的一个。在实际应用中，可以根据实际应用的需求确定 第一开口间距、第二开口间距以及第三开口间距之间的比值的具体数值，在此不作限定。
示例性地，如图4与图6所示，第三颜色像素spx3中，在第一方向F1上，黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK3的底端在衬底基板100的正投影的边缘具有第三开口间距b21。其中，第三开口间距b21不小于第一开口间距r21，且小于第二开口间距g21。示例性地，r21:b21为1:1～1:1.2。可选地，r21:b21为1:1、1:1.1、1:1.2中的一个。进一步地，r21:g21:b21为1:1:1.2～1:1.2:2.2。在实际应用中，可以根据实际应用的需求确定r21:b21的具体数值，在此不作限定。
示例性地，如图4与图5所示，第三颜色像素spx3中，在第二方向F2上，黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK3的底端在衬底基板100的正投影的边缘具有第三开口间距b22。其中，第三开口间距b22不小于第一开口间距r22，且小于第二开口间距g22。示例性地，r22:b22为1:1～1:1.2。可选地，r22:b22为1:1、1:1.1、1:1.2中的一个。进一步地，r22:g22:b22为1:1:1.2～1:1.2:2.2。在实际应用中，可以根据实际应用的需求确定r22:b22的具体数值，在此不作限定。
可选地，可以将第一开口间距r21与r22设置为相同。这样可以使第一颜色像素spx1中的黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK1的底端在衬底基板100的正投影的边缘之间的间距统一设置，提高像素开口的设置均一性。
可选地，可以将第二开口间距g21与g22设置为相同。这样可以使第二颜色像素spx2中的黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK2的底端在衬底基板100的正投影的边缘之间的间距统一设置，提高像素开口的设置均一性。
可选地，可以将第三开口间距b21与b22设置为相同。这样可以使第三颜色像素spx3中的黑矩阵开口的底端在衬底基板100的正投影的边缘与像素开口KK3的底端在衬底基板100的正投影的边缘之间的间距统一设置，提高 像素开口的设置均一性。
在本申请实施例中，如图4与图5所示，显示面板还包括：第一折射率层150和第二折射率层160。其中，第一折射率层150位于像素限定层170背离衬底基板100一侧，第二折射率层160位于第一折射率层150背离衬底基板100一侧。并且，第一折射率层150和第二折射率层160的折射率不同。例如，第一折射率层150的折射率小于第二折射率层160的折射率。并且，第一折射率层150具有调整结构，调整结构与第一颜色像素spx1对应设置。其中，调整结构被配置为降低从第一颜色像素spx1的像素开口出射光线的出射角，从而使得从第一颜色像素spx1的像素开口出射的光线从显示面板出射后的出射角减小。这样通过调整结构，可以使从第一颜色像素spx1的像素开口出射的部分光线被黑矩阵130吸收，以减少在大视角下从第一颜色像素spx1的像素开口发出的光束亮度衰减的速率，使得第一颜色像素spx1的像素开口发出的光线的视角亮度衰减速率与第二颜色像素spx2的像素开口所发出的光线的视角亮度衰减率尽量保持一致，进而可以减小显示面板的色偏。
示例性地，如图4与图5所示，调整结构可以包括凹槽AX，且凹槽AX的侧壁呈斜坡状，第二折射率层160填充凹槽AX。该凹槽AX与第一颜色像素spx1对应设置，且第一颜色像素spx1的像素开口的底端在衬底基板100的正投影覆盖凹槽AX的底端在衬底基板100的正投影。示例性地，凹槽AX的截面为倒梯形，凹槽AX的底端为倒梯形短边，凹槽AX的顶端为倒梯形长边。由于凹槽AX的截面为倒梯形，凹槽AX的侧壁呈斜坡状，由于第二折射率层160的折射率大于第一折射率层150的折射率，通过设计凹槽AX的侧壁的倾斜角β的具体数值，可以在凹槽AX的侧壁处会形成全反射平面，第一颜色像素spx1的像素开口的边缘(如右侧边缘)出射的光L11，入射到凹槽AX左侧的侧壁处S1时，能够发生全反射。同理，第一颜色像素spx1的像素开口的左侧边缘出射的光，入射到凹槽AX右侧的侧壁处时，也能够发生全反射。这样可以将第一颜色像素spx1的像素开口出射的光，能够被汇聚到正视角出射，可以增加在大视角下从第一颜色像素spx1的像素开口发出的光束亮 度衰减的速率，使得第一颜色像素spx1的像素开口发出的光线的视角亮度衰减速率与第二颜色像素spx2的像素开口所发出的光线的视角亮度衰减速率尽量保持一致，进而可以减小显示面板的色偏。
示例性地，如图7所示，第一颜色像素spx1的像素开口的底端在衬底基板100的正投影的边缘与凹槽AX的底端在衬底基板100的正投影的边缘之间具有第一内缩值ns1，第一内缩值ns1不小于零且不大于2μm，即0≤ns1≤2μm。这样可以使从第一颜色像素spx1的像素开口的边缘(如右侧边缘)出射的光L11，入射到凹槽AX左侧的侧壁处S1时，能够发生全反射。
可选地，ns1＝0，则第一颜色像素spx1的像素开口的底端在衬底基板100的正投影的边缘与凹槽AX的底端在衬底基板100的正投影的边缘重叠。或者，0＜ns1≤2μm，则第一颜色像素spx1的像素开口的底端在衬底基板100的正投影的边缘与凹槽AX的底端在衬底基板100的正投影的边缘不重叠，且凹槽AX的底端在衬底基板100的正投影的边缘内缩于第一颜色像素spx1的像素开口的底端在衬底基板100的正投影的边缘内。这样可以进一步使从第一颜色像素spx1的像素开口的边缘(如右侧边缘)出射的光L11，入射到凹槽AX左侧的侧壁处S1时，能够发生全反射。可选地，ns1为0.5μm、1.0μm、1.5μm、2μm中的一个。在实际应用中，ns1的具体数值可以根据实际应用的环境确定，在此不作限定。
示例性地，如图4与图5所示，第一颜色像素spx1的像素开口KK1的顶端在衬底基板100的正投影覆盖凹槽AX的顶端在衬底基板100的正投影。这样可以进一步使从第一颜色像素spx1的像素开口KK1的边缘(如右侧边缘)出射的光L11，入射到凹槽AX左侧的侧壁处S1时，能够发生全反射。当然，也可以使第一颜色像素的像素开口的顶端在衬底基板的正投影位于凹槽的顶端在衬底基板的正投影内，在此不作限定。
如图10a至图10b所示，图10a为图4所示的显示面板采用红绿蓝三原色光混合白光时的W视角CIE(Commission Internationale d'Eclairage)轨迹图。图10b为图4所示的显示面板的单色视角亮度衰减图，图10c为图4所示的 显示面板采用红绿蓝三原色光混合白光时的W视角色偏和W视角亮度衰减比例的具体参数对比示意图。图10b中，LR11代表红色像素单色视角亮度的衰减曲线，LG11代表绿色像素单色视角亮度的衰减曲线，LB11代表蓝色像素单色视角亮度的衰减曲线。由图10a至图10b可以看出，采用本公开实施例提供的显示面板，在不同视角下不同颜色的OLED的亮度衰减速率趋于一致，在采用RGB混合白光时，不同视角下显示面板在画面显示时的色偏得以改善。
本公开实施例提供了另一些显示面板的结构示意图，如图11所示。其针对上述实施例中的实施方式进行了变形。下面仅说明本实施例与上述实施例的区别之处，其相同之处在此不作赘述。
在本公开一些实施例中，如图11与图12所示，调整结构也可以包括凹透镜阵列TZ；第二折射率层160填充凹透镜阵列TZ。凹透镜阵列TZ与第二颜色像素spx2对应设置，且第二颜色像素spx2的像素开口KK2的底端在衬底基板100的正投影覆盖凹透镜阵列TZ所在区域在衬底基板100的正投影。由于第二折射率层160的折射率大于第一折射率层150的折射率，从第二颜色像素spx2的像素开口KK2出射的光，入射到凹透镜阵列TZ时，光由光疏介质进入光密介质，按照凹透镜的球心为法线，该光线的方向发生变化，可以降低在大视角下从第二颜色像素spx2的像素开口发出的光束亮度衰减的速率，使得第一颜色像素spx1的像素开口KK1发出的光线的视角亮度衰减速率与第二颜色像素spx2的像素开口KK2所发出的光线的视角亮度衰减速率尽量保持一致，进而可以减小显示面板的色偏。
在本公开一些实施例中，如图11与图12所示，凹透镜阵列TZ中，各凹透镜的尺寸相同。示例性地，凹透镜阵列TZ中的各凹透镜在衬底基板100的正投影为圆形，凹透镜的尺寸可以为圆形的正投影的直径。也就是说，凹透镜阵列TZ中的各凹透镜在衬底基板100的正投影的直径相同。
在本公开一些实施例中，如图8与图12所示，凹透镜阵列TZ中，每相邻两个凹透镜之间的间隔距离相同。示例性地，凹透镜阵列TZ中的每相邻两个凹透镜在衬底基板100的正投影的圆心之间的距离相同。

在本公开一些实施例中，如图13所示，调整结构既可以包括凹槽AX，又可以包括凹透镜阵列TZ。其中，凹槽AX与第一颜色像素spx1对应设置，凹透镜阵列TZ与第二颜色像素spx2对应设置。需要说明的是，凹槽AX和凹透镜阵列TZ的实施方式，可以参照上述实施方式，在此不作赘述。
本公开实施例中，可以通过凹槽AX和凹透镜阵列TZ这两种方式的相互结合，使得第一颜色像素spx1的像素开口发出的光线的视角亮度衰减速率与第二颜色像素spx2的像素开口所发出的光线的视角亮度衰减速率尽量保持一致，进而可以减小显示面板的色偏。

示例性地，第四尺寸g32_1和g32_2可以相同，这样可以统一设计第二 颜色像素spx2_1和spx2_2的第四尺寸，提高显示面板的设计均一性。
在本公开一些实施例中，如图14与图15所示，一个第二颜色像素spx2_1的像素开口KK2_1的面积小于一个第三颜色像素spx3的像素开口KK3的面积。在一些示例中，在第一方向F1上，一个第三颜色像素spx3的像素开口KK3具有第五尺寸b31。且第五尺寸b31大于第二尺寸g31_1。示例性地，r31:g31_1:b31为1:1.2:1.7～1:1.6:1.9。可选地，r31:g31_1:b31为1:1.2:1.7、1:1.2:1.8、1:1.2:1.9、1:1.3:1.7、1:1.3:1.8、1:1.6:1.7、1:1.6:1.8、1:1.6:1.9中的一个。在实际应用中，可以根据实际应用的需求确定r31:g31_1:b31的具体数值，在此不作限定。

在本公开一些实施例中，如图14与图15所示，在第二方向F2上，一个第三颜色像素spx3的像素开口KK3具有第六尺寸b32。且第六尺寸b32大于第四尺寸g32_1。示例性地，r32:g32_1:b32为1:1.2:1.7～1:1.6:1.9。可选地，r32:g32_1:b32为1:1.2:1.7、1:1.2:1.8、1:1.2:1.9、1:1.3:1.7、1:1.3:1.8、1:1.6:1.7、1:1.6:1.8、1:1.6:1.9中的一个。在实际应用中，可以根据实际应用的需求确定r32:g32_1:b32的具体数值，在此不作限定。
在本公开一些实施例中，如图14与图15所示，在第二方向F2上，一个第三颜色像素spx3的像素开口KK3具有第六尺寸b32。且第六尺寸b32大于第四尺寸g32_2。示例性地，r32:g32_2:b32为1:1.2:1.7～1:1.6:1.9。可选地，r32:g32_2:b32为1:1.2:1.7、1:1.2:1.8、1:1.2:1.9、1:1.3:1.7、1:1.3:1.8、1:1.6:1.7、 1:1.6:1.8、1:1.6:1.9中的一个。在实际应用中，可以根据实际应用的需求确定r32:g32_2:b32的具体数值，在此不作限定。
示例性地，如图14所示，第一折射率层150的调整结构可以包括凹槽AX，且凹槽AX的侧壁呈斜坡状，第二折射率层160填充凹槽AX。该凹槽AX与第一颜色像素spx1对应设置，且第一颜色像素spx1的像素开口KK1的底端在衬底基板100的正投影覆盖凹槽AX的底端在衬底基板100的正投影。示例性地，凹槽AX的截面为倒梯形，凹槽AX的底端为倒梯形短边，凹槽AX的顶端为倒梯形长边。由于凹槽AX的截面为倒梯形，凹槽AX的侧壁呈斜坡状，由于第二折射率层160的折射率大于第一折射率层150的折射率，通过设计凹槽AX的侧壁的倾斜角β的具体数值，可以在凹槽AX的侧壁处会形成全反射平面，第一颜色像素spx1的像素开口的边缘(如右侧边缘)出射的光L11，入射到凹槽AX左侧的侧壁处S1时，能够发生全反射。同理，第一颜色像素spx1的像素开口的左侧边缘出射的光，入射到凹槽AX右侧的侧壁处时，也能够发生全反射。并且，第一颜色像素spx1的像素开口的中间区域出射的光，入射到凹槽AX左侧和右侧的侧壁处时，不会发生全反射，可以折射出去。从而使第一颜色像素spx1的像素开口出射的部分光线能够出射到显示面板外面，实现发光，并且从第一颜色像素spx1的像素开口出射的另一部分光线被黑矩阵130吸收，可以增加在大视角下从第一颜色像素spx1的像素开口发出的光束亮度衰减的速率，使得第一颜色像素spx1的像素开口发出的光线的视角亮度衰减速率与第二颜色像素spx2的像素开口所发出的光线的视角亮度衰减速率尽量保持一致，进而可以减小显示面板的色偏。
需要说明的是，本实施例中凹槽AX的实施方式，可以参照上述实施方式，在此不作赘述。
如图17a至图17b所示，图17a为相关技术中OLED显示面板采用红绿蓝三原色光混合白光时的W视角CIE(Commission Internationale d'Eclairage)轨迹图。图17b为相关技术中红色OLED(如R)、绿色OLED(如G)以及蓝色OLED(如B)的单色视角亮度衰减图，图17c为相关技术中OLED显 示面板采用红绿蓝三原色光混合白光时的W视角色偏和W视角亮度衰减比例的具体参数对比示意图。由图17a至图17b可以看出，不同视角下不同颜色的OLED的亮度衰减速率不一致，其中，红色OLED的亮度衰减较慢，绿色OLED的亮度衰减较快，在采用RGB混合白光时，不同视角下显示面板在画面显示时会发生色偏的现象。
如图18a至图18b所示，图18a为图14所示的显示面板采用红绿蓝三原色光混合白光时的W视角CIE(Commission Internationale d'Eclairage)轨迹图。图18b为图14所示的显示面板的单色视角亮度衰减图，图18c为图14所示的显示面板采用红绿蓝三原色光混合白光时的W视角色偏和W视角亮度衰减比例的具体参数对比示意图。图18b中，LR21代表红色像素单色视角亮度的衰减曲线，LG21代表绿色像素单色视角亮度的衰减曲线，LB21代表蓝色像素单色视角亮度的衰减曲线。由图18a至图18b可以看出，采用本公开实施例提供的显示面板，在不同视角下不同颜色的OLED的亮度衰减速率趋于一致，在采用RGB混合白光时，不同视角下显示面板在画面显示时的色偏得以改善。
本公开实施例提供了又一些显示面板的结构示意图，如图19所示。其针对上述实施例中的实施方式进行了变形。下面仅说明本实施例与上述实施例的区别之处，其相同之处在此不作赘述。
在本公开一些实施例中，如图19与图20所示，第一折射率层150的调整结构也可以包括凹透镜阵列TZ；第二折射率层160填充凹透镜阵列TZ。凹透镜阵列TZ与第二颜色像素spx2_1和spx2_2对应设置。即，第二颜色像素spx2_1设置凹透镜阵列TZ，且第二颜色像素spx2_1的像素开口KK2_1的底端在衬底基板100的正投影覆盖凹透镜阵列TZ所在区域在衬底基板100的正投影。第二颜色像素spx2_2也设置凹透镜阵列TZ，且第二颜色像素spx2_2的像素开口KK2_2的底端在衬底基板100的正投影覆盖凹透镜阵列TZ所在区域在衬底基板100的正投影。由于第二折射率层160的折射率大于第一折射率层150的折射率，从第二颜色像素spx2_1和spx2_2的像素开口出射的光， 入射到凹透镜阵列TZ时，光由光疏介质进入光密介质，按照凹透镜的球心为法线，该光线的方向发生变化，可以降低在大视角下从第二颜色像素spx2的像素开口发出的光束亮度衰减的速率，使得第一颜色像素spx1的像素开口发出的光线的视角亮度衰减速率与第二颜色像素spx2的像素开口所发出的光线的视角亮度衰减速率尽量保持一致，进而可以减小显示面板的色偏。
需要说明的是，本实施例中凹透镜阵列TZ的实施方式，可以参照上述实施方式，在此不作赘述。
如图21a至图21b所示，图21a为图19所示的显示面板采用红绿蓝三原色光混合白光时的W视角CIE(Commission Internationale d'Eclairage)轨迹图。图21b为图19所示的显示面板的单色视角亮度衰减图，图21c为图19所示的显示面板采用红绿蓝三原色光混合白光时的W视角色偏和W视角亮度衰减比例的具体参数对比示意图。图21b中，LR22代表红色像素单色视角亮度的衰减曲线，LG22代表绿色像素单色视角亮度的衰减曲线，LB22代表蓝色像素单色视角亮度的衰减曲线。由图21a至图21b可以看出，采用本公开实施例提供的显示面板，在不同视角下不同颜色的OLED的亮度衰减速率趋于一致，在采用RGB混合白光时，不同视角下显示面板在画面显示时的色偏得以改善。

如图23a至图23b所示，图23a为图22所示的显示面板采用红绿蓝三原色光混合白光时的W视角CIE(Commission Internationale d'Eclairage)轨迹图。 图23b为图22所示的显示面板的单色视角亮度衰减图，图23c为图22所示的显示面板采用红绿蓝三原色光混合白光时的W视角色偏和W视角亮度衰减比例的具体参数对比示意图。图23b中，LR23代表红色像素单色视角亮度的衰减曲线，LG23代表绿色像素单色视角亮度的衰减曲线，LB23代表蓝色像素单色视角亮度的衰减曲线。由图23a至图23b可以看出，采用本公开实施例提供的显示面板，在不同视角下不同颜色的OLED的亮度衰减速率趋于一致，在采用RGB混合白光时，不同视角下显示面板在画面显示时的色偏得以改善。
