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，都属于本公开的保护范围。
需要说明的是，在附图中，为了清楚和/或描述的目的，可以放大元件的尺寸和相对尺寸。如此，各个元件的尺寸和相对尺寸不必限于图中所示的尺寸和相对尺寸。在说明书和附图中，相同或相似的附图标号指示相同或相似的部件。
当元件被描述为“在”另一元件“上”、“连接到”另一元件或“结合到”另一元件时，所述元件可以直接在所述另一元件上、直接连接到所述另一元件或直接结合到所述另一元件，或者可以存在中间元件。然而，当元件被描述为“直接在”另一元件“上”、“直接连接到”另一元件或“直接结合到”另一元件时，不存在中间元件。用于描述元件之间的关系的其他术语和/或表述应当以类似的方式解释，例如，“在......之间”对“直接在......之间”、“相邻”对“直接相邻”或“在......上”对“直接在......上”等。此外，术语“连接”可指的是物理连接、电连接、通信连接和/或流体连接。此外，X轴、Y轴和Z轴不限于直角坐标系的三个轴，并且可以以更广泛的含义解释。例如，X轴、Y轴和Z轴可彼此垂直，或者可代表彼此不垂直的不同方向。出于本公开的目的，“X、Y和Z中的至少一个”和“从由X、Y和Z构成的组中选择的至少一个”可以被解释为仅X、仅Y、仅Z、或者诸如XYZ、XYY、YZ和ZZ的X、Y和Z中的两个或更多个的任何组合。如文中所使用的，术语“和/或”包括所列相关项中的一个或多个的任何组合和所有组合。
需要说明的是，虽然术语“第一”、“第二”等可以在此用于描述各种部件、构件、元件、区域、层和/或部分，但是这些部件、构件、元件、区域、层和/或部分不应受到这些术语限制。而是，这些术语用于将一个部件、构件、元件、区域、层和/或部分与另一个相区分。因而，例如，下面讨论的第一部件、第一构件、第一元件、第一区域、第一层和/或第一部分可以被称为第二部件、第二构件、第二元件、第二区域、第二层和/或第二部分，而不背离本公开的教导。
为了便于描述，空间关系术语，例如，“上”、“下”、“左”、“右”等可以在此被使用，来描述一个元件或特征与另一元件或特征如图中所示的关系。应理解，空间关系术语意在涵盖除了图中描述的取向外，装置在使用或操作中的其它不同取向。例如，如果图中的装置被颠倒，则被描述为“在”其它元件或特征“之下”或“下面”的元件将取向为“在”其它元件或特征“之上”或“上面”。
在本文中，表述“重复单元”表示多个子像素的组合，例如，用来显示一个像素点的多个子像素的组合，多个“重复单元”在衬底基板上成阵列地重复排列。例如，一个重复单元可以包括2个、3个、4个、或更多个子像素。此外，在本文中，为了描述方便，将位于第一显示区域中的重复单元称为第一重复单元，将位于第二显示区域中的重复单元称为第二重复单元。
在本文中，表述“像素密度”表示单位面积内的重复单元或子像素的个数。类似地，表述“分布密度”表示单位面积内的部件(例如重复单元、子像素、隔垫物等)的个数。
本公开的实施例提供一种显示面板，所述显示面板包括第一显示区域和第二显示区域，其中，所述显示面板包括：衬底基板；多个第一重复单元，所述多个第一重复单元成阵列地设置于所述衬底基板，且位于所述第一显示区域中，每一个所述第一重复单元至少包括第一子像素；多个第二重复单元，所述多个第二重复单元成阵列地设置于所述衬底基板，且位于所述第二显示区域中，每一个所述第二重复单元至少包括第二子像素，所述第一子像素与所述第二子像素发出的光的颜色相同；像素界定层，所述像素界定层设置于所述衬底基板，且位于所述第一显示区域和所述第二显示区域中，所述像素界定层包括位于所述第一显示区域的第一开口和所述位于所述第二显示区域的第二开口，其中，所述第一显示区域的像素密度大于所述第二显示区域的像素密度；并且，所述第一子像素包括所述第一开口，所述第二子像素包括所述第二开口，所述第二开口在所述衬底基板上的正投影的面积大于所述第一开口在所述衬底基板上的正投影的面积。通过这样的方式，可以提高第一显示区域和第二显示区域的显示均一性，并且还可以提高第一显示区域和第二显示区域中的发光材料的寿命的均一性。
图1是根据本公开的一些示例性实施例的显示面板的平面示意图。图2是根据本公开的一些示例性实施例的显示面板沿图1中的线AA’截取的截面示意图。图3是图1中的显示面板的局部放大示意图，图中每个虚线框表示一个重复单元，每个矩形表 示一个子像素。
参照图1至图3，显示面板包括第一显示区域AA1和被第一显示区域AA1至少部分围绕的第二显示区域AA2。该第一显示区域AA1包括阵列排布的多个第一重复单元P1，该第二显示区域AA2包括阵列排布的多个第二重复单元P2。第一重复单元P1可以进一步包括多个子像素，例如红色子像素、绿色子像素、蓝色子像素；同样地，第二重复单元P2可以进一步包括多个子像素，例如红色子像素、绿色子像素、蓝色子像素。
需要说明的是，以红色、绿色和蓝色为例对本公开的实施例进行说明，但是，本公开实施例不局限于此，也就是说，每一个重复单元可以包括第一颜色子像素、第二颜色子像素和第三颜色子像素，第一颜色、第二颜色和第三颜色为彼此不同的颜色。在本文中，为了描述方便，将第一重复单元P1包括的各个子像素分别称为第一子像素、第三子像素和第五子像素，将第二重复单元P2包括的各个子像素分别称为第二子像素、第四子像素和第六子像素。例如，第一子像素和第二子像素可以为红色子像素，第三子像素和第四子像素可以为蓝色子像素，第五子像素和第六子像素可以为绿色子像素。但是，本公开的实施例不局限于此，在其他实施例中，每一个重复单元可以包括4个子像素，例如，第一重复单元P1可以包括第一子像素、第三子像素、第五子像素和第七子像素，第二重复单元P2可以包括第二子像素、第四子像素、第六子像素和第八子像素。例如，每一个重复单元包括的4个子像素中的2个子像素可以组成1个像素单元，每一个重复单元包括的4个子像素中的另2个子像素可以组成另1个像素单元，即，每一个重复单元可以包括2个像素单元。
需要说明的是，在图示的示例性实施例中，第一显示区域AA1包围第二显示区域AA2，但是，本公开的实施例不局限于此。例如，在其它实施例中，第二显示区域AA2可以位于显示面板的上侧边缘的位置，例如，第二显示区域AA2的三侧被第一显示区域AA1包围，其上侧与显示面板的上侧平齐。再例如，第二显示区域AA2可以位于显示面板的上侧边缘的位置，并且沿显示面板的整个宽度布置。
如图3所示，第一显示区域AA1具有第一像素密度，并且该第二显示区域AA2具有小于第一像素密度的第二像素密度。
在第二显示区域AA2中，多个第二重复单元P2之间的空白区域可以允许更多的光透过，从而提高该区域的光透过率。因此，相比于第一显示区域AA1，第二显示区 域AA2具有更大的光透过率。
需要说明的是，在本文中，多个第二重复单元P2之间的空白区域可以称为透光区域TRA。
如图2所示，所述显示面板可以包括衬底基板1。图像传感器2可以设置到衬底基板1的位于第二显示区域AA2的背面(在图2中示出为下侧)，第二显示区域AA2可以满足图像传感器2对于光透过率的成像要求。
在图1至图3所示的显示面板中，可以采用OLED显示技术。由于OLED显示面板具有广视角、高对比度、快响应、低功耗、可折叠、柔性等优势，在显示产品中得到越来越广泛地应用。随着OLED显示技术的发展和深入应用，对高屏占比显示屏的需求越来越强烈。在图1至图3所示的显示面板中，采用了屏下摄像头的方案。这样，可以消除notch区，避免在显示屏中挖孔，并且能够提高屏占比，具有较佳的视觉体验。
此外，所述显示面板还可以包括设置在衬底基板1上的驱动电路层、发光器件层和封装层。例如，图2中示意性地示出了驱动电路层3、发光器件层4和封装层5。驱动电路层3包括驱动电路结构，发光器件层4包括例如OLED的发光器件。所述驱动电路结构控制各个子像素的发光器件发光，以实现显示功能。该驱动电路结构包括薄膜晶体管、存储电容器以及各种信号线。所述各种信号线包括栅线、数据线、ELVDD电源线和ELVSS电源线等，以便为每个子像素中的像素驱动电路提供控制信号、数据信号、电源电压等各种信号。
图4是图3中的部分I的局部放大示意图。图5是根据本公开的一些示例性实施例沿图4中的线BB’截取的截面示意图。结合参照图4和图5，所述显示面板可以包括：设置在衬底基板1上阳极41；设置在阳极41远离衬底基板1一侧的像素界定层6；设置在像素界定层6远离衬底基板1一侧的发光层42；以及设置在发光层42远离衬底基板1一侧的阴极43。
应该理解，发光层42例如可以是有机发光层，相应地，阳极41、有机发光层42和阴极43构成上述例如OLED的发光器件。
如图4和图5所示，像素界定层6可以包括多个开口62。多个开口62分别位于多个子像素中，例如，每一个子像素中设置有一个开口62。每一个开口62暴露阳极41的一部分。发光层42的一部分填充于该开口62中，以与暴露的阳极41的部分接 触。
每一个子像素的实际发光面积由发光层42与阳极41接触的部分的面积决定，即，由像素界定层6的每一个开口62的面积决定，更具体地说，由每一个开口62在衬底基板1上的正投影的面积决定。
另外，考虑到相邻的两个子像素之间混色的影响，相邻的两个子像素(例如子像素SP1和SP2)之间的开口62之间需要间隔规定的距离，如图4中的距离d所示。
这样，在每一个子像素中，开口62的面积(即实际发光面积)小于所述子像素的整个像素面积。
在本文中，可以使用每一个子像素的实际发光面积占所述子像素的整个像素面积的比例来表示该子像素的开口率。如上所述，子像素的实际发光面积由每一个开口62在衬底基板1上的正投影的面积决定。另外，所述子像素的整个像素面积可以采用以下方式确定。例如，本领域技术人员应该理解，每一个子像素都具有各自的像素电路，像素电路在衬底基板上成周期性排列。所以，一个子像素的整个像素面积可以通过计算其像素电路在衬底基板上的正投影的面积确定。结合参照图4，子像素的开口率可以用以下公式表示：
Figure PCTCN2020088328-appb-000001
其中，A.R.表示子像素的开口率，S R表示子像素的实际发光面积，S pixel表示子像素的整个像素面积。
图6A是根据本公开的一些示例性实施例的显示面板的位于第一显示区域中的一个第一重复单元的平面示意图，图6B是根据本公开的一些示例性实施例的显示面板的位于第二显示区域中的一个第二子重复单元的平面示意图。
例如，图6A中示出的一个第一重复单元P1可以包括第一子像素SP1(例如红色子像素)、第三子像素SP3(例如蓝色子像素)和第五子像素SP5(例如绿色子像素)；图6B中示出的一个第二重复单元P2可以包括第二子像素SP2(例如红色子像素)、第四子像素SP4(例如蓝色子像素)和第六子像素SP6(例如绿色子像素)。第一子像素SP1、第三子像素SP3和第五子像素SP5发出的光的颜色分别与第二子像素SP2、第四子像素SP4和第六子像素SP6发出的光的颜色相同。
如上所述，位于第一显示区域AA1和第二显示区域AA2中的子像素均具有开口，为了方便描述，将第一子像素SP1、第二子像素SP2、第三子像素SP3、第四子像素 SP4、第五子像素SP5和第六子像素SP6具有的开口分别称为第一开口62A、第二开口62B、第三开口62C、第四开口62D、第五开口62E和第六开口62F。
参照图6A和图6B，在本公开的实施例中，第二开口62B在衬底基板1上的正投影的面积大于第一开口62A在衬底基板1上的正投影的面积。
这样，在本公开的实施例中，由于第二开口62B的面积大于第一开口62A的面积，所以，位于第二显示区域AA2中的子像素的实际发光面积大于位于第一显示区域AA1中具有相同颜色的子像素的实际发光面积。进一步地，由于子像素的实际发光面积决定了该子像素的发光亮度，所以，位于第二显示区域AA2中的子像素的发光亮度大于位于第一显示区域AA1中具有相同颜色的子像素的发光亮度。考虑到第一显示区域AA1的像素密度大于第二显示区域AA2的像素密度，在本公开的实施例中，通过使得位于第二显示区域AA2中的子像素的实际发光面积大于位于第一显示区域AA1中具有相同颜色的子像素的实际发光面积，提高了第一显示区域AA1中的各个重复单元的发光亮度与第二显示区域AA2中的各个重复单元的发光亮度的均一性，从而提高了显示均一性。
另外，在本公开的实施例中，通过增大实际发光面积的方式，来提高位于第二显示区域AA2中的子像素的发光亮度，所以，不需要采用其他方式(例如增加驱动电流)来提高位于第二显示区域AA2中的子像素的发光亮度，从而有利于提高位于第二显示区域AA2中的各个子像素的发光材料的寿命。以此方式，使得位于第二显示区域AA2中的各个子像素的发光材料的寿命与位于第一显示区域AA1中的各个子像素的发光材料的寿命的均一性得到提高。
继续参照图6A和图6B，在本公开的实施例中，第四开口62D在衬底基板1上的正投影的面积大于第三开口62C在衬底基板1上的正投影的面积。可选地或附加地，第六开口62F在衬底基板1上的正投影的面积大于第五开口62E在衬底基板1上的正投影的面积。通过这样的方式，可以进一步提高第一显示区域和第二显示区域之间的显示均一性，并提高位于第一显示区域和第二显示区域中的各个子像素的发光材料的寿命的均一性。
例如，在图6A和图6B所示的实施例中，第一开口62A、第二开口62B、第三开口62C、第四开口62D、第五开口62E和第六开口62F中的每一个在衬底基板1上的正投影具有矩形形状。
所述矩形具有在行方向X上的第一尺寸和在列方向Y上的第二尺寸。例如，第一开口62A可以具有沿行方向X的第一宽度W1(即第一尺寸)和沿列方向Y的第一长度L1(即第二尺寸)，第二开口62B可以具有沿行方向X的第二宽度W2(即第一尺寸)和沿列方向Y的第二长度L2(即第二尺寸)。
所述第二开口62B的第一尺寸大于所述第一开口62A的第一尺寸，所述第二开口62B的第二尺寸大于所述第一开口62A的第二尺寸。示例性地，第二宽度W2可以大于第一宽度W1，和/或，第二长度L2可以大于第一长度L1。
在一些示例性的实施例中，第二宽度W2可以等于(1+n)W1，第二长度L2可以等于(1+n)L1，其中，n为大于0的数。这样，第二开口62B的面积为第一开口62A的面积的(1+n) 2倍。
在本文中，为了描述方便，可以将n称为外扩系数。
例如，n可以等于约9％，即，第二宽度W2相对于第一宽度W1增加约9％，第二长度L2相对于第一长度L1增加约9％。这样，第二开口62B的面积为第一开口62A的面积的约1.19倍。发明人经研究发现，当n设置为小于等于9％时，可以避免相邻的两个子像素发出的光产生混色的风险。也就是说，通过将n设置为约9％，可以在避免产生混色的情况下尽量提高第一显示区域和第二显示区域之间的显示均一性和发光材料寿命的均一性。此外，由于用于蒸镀工艺的FMM(即精细掩模板)在设计时就有一定的容差设计，FMM的开口会比对应的子像素的开口略大一些，在本公开的实施例中，将像素界定层限定的开口略做外扩(例如9％以内)，该外扩在上述容差设计的范围内，所以，在本公开的实施例中，不需要改变FMM的设计，从而有利于生产工艺，并且节省制造成本。
可选地，所述第四开口62D的第一尺寸W4大于所述第三开口62C的第一尺寸W3，所述第四开口62D的第二尺寸L4大于所述第三开口62C的第二尺寸L3。
可选地，所述第六开口62F的第一尺寸W6大于所述第五开口62E的第一尺寸W5，所述第六开口62F的第二尺寸L6大于所述第五开口62E的第二尺寸L5。
例如，在图6A和图6B所示的示例性实施例中，对于具有第一颜色的第一子像素SP1和第二子像素而言，W2可以等于(1+n 1)W1，L2可以等于(1+n 1)L1，其中，n 1为大于0的数。这样，第二开口62B的面积为第一开口62A的面积的(1+n 1) 2倍。对于具有第二颜色的第三子像素SP3和第四子像素SP4而言，W4可以等于(1+n 2) W3，L4可以等于(1+n 2)L3，其中，n 2为大于0的数。这样，第四开口62D的面积为第三开口62C的面积的(1+n 2) 2倍。对于具有第三颜色的第五子像素SP5和第六子像素SP6而言，W6可以等于(1+n 3)W5，L6可以等于(1+n 3)L5，其中，n 3为大于0的数。这样，第六开口62F的面积为第五开口62E的面积的(1+n 3) 2倍。
例如，n 1、n 2和n 3可以彼此相等。也就是说，不同颜色的子像素的外扩系数可以设置为彼此相同。例如，它们都可以等于约9％。这样，不同颜色的子像素的开口等比例地外扩，有利于工艺实现。
可选地，n 1、n 2和n 3可以彼此不相等。也就是说，不同颜色的子像素的外扩系数可以设置为彼此不同。可选地，n 1、n 2和n 3中的2个可以彼此相等。这样，可以为不同颜色的子像素设计不同的外扩系数，可以增加设计的灵活性。
应该理解，n 1、n 2和n 3可以在9％的范围内，即它们可以小于等于9％。
可选地，在本公开的一些实施例中，上述的外扩系数n 1、n 2和n 3可以大于0小于30％，例如，可以为5％，10％，15％，20％等。
结合参照图4和图5，对于每一个重复单元的一个子像素而言，开口62在衬底基板1上的正投影落入阳极41在衬底基板1上的正投影内，开口62的边缘与阳极41的边缘之间间隔一定的距离，如图4中的d1所示。例如，对于第一重复单元P1的一个子像素而言，该距离d1可以等于约3.9微米；对于第二重复单元P1的一个子像素而言，该距离d1可以等于约2.0微米。这样，第一重复单元P1中相邻的两个子像素之间的开口62之间间隔的距离d比第二重复单元P2中相邻的两个子像素之间的开口62之间间隔的距离d大约3.8微米。可选地，在本公开的实施例中，第二重复单元P2中相邻的两个子像素之间的开口62之间间隔的距离d在4微米以上，例如，在4～20微米之间。当第二重复单元P2中相邻的两个子像素之间的开口62之间间隔的距离d小于4微米时，相邻的两个子像素之间混色的风险较高。相应地，第一重复单元P1中相邻的两个子像素之间的开口62之间间隔的距离d比第二重复单元P2中相邻的两个子像素之间的开口62之间间隔的距离d至少大3微米。
图7是根据本公开的一些示例性实施例的显示面板的平面示意图。参照图7，所述显示面板包括沿行方向X和列方向Y成阵列排列的多个重复单元。其中，一些重复单元P1(即第一重复单元)位于第一显示区域AA1，另一些重复单元P2(即第二重 复单元)位于第二显示区域AA2。第一显示区域AA1的像素密度大于第二显示区域AA2的像素密度。
每一个重复单元可以包括4个子像素。具体地，第一重复单元P1可以包括第一子像素SP1、第三子像素SP3、第五子像素SP5和第七子像素SP7，第二重复单元P2可以包括第二子像素SP2、第四子像素SP4、第六子像素SP6和第八子像素SP8。其中，相邻的第五子像素SP5和第七子像素SP7可以组成一个子像素组，相邻的第六子像素SP6和第八子像素SP8也可以组成一个子像素组。
例如，第五子像素SP5和第七子像素SP7以及第六子像素SP6和第八子像素SP8可为人眼敏感颜色的子像素，例如可为绿色子像素、黄色子像素、白色子像素等。例如，相比于第一子像素SP1至第四子像素SP4，第五子像素SP5和第七子像素SP7以及第六子像素SP6和第八子像素SP8每一个的面积相对较小。
第一子像素SP1、第二子像素SP2、第三子像素SP3和第四子像素SP4可为人眼不敏感颜色的子像素。例如，第一子像素SP1和第二子像素SP2为红色子像素，第三子像素SP3和第四子像素SP4为蓝色子像素，但本公开的实施例不限于此。在本公开的一些示例性实施例中，以第一子像素SP1和第二子像素SP2为红色子像素，第三子像素SP3和第四子像素SP4为蓝色子像素为例进行说明。需要说明的是，当像素排列结构采用红绿蓝(RGB)模式时，上述的人眼敏感颜色可为绿色。
在根据本公开的实施例中，通过这样排列各个子像素，可以提高像素排列结构视觉上的分辨率，从而提高显示质量。此外，第五子像素和第六子像素以及第七子像素和第八子像素为相同颜色，可以使得同一个子像素组中的2个子像素的发光材料层应用掩模板的同一开口蒸镀形成，从而能够降低制备这些子像素中的发光材料层的工艺难度。
同样地，结合参照图5，所述显示面板可以包括：设置在衬底基板1上阳极41；设置在阳极41远离衬底基板1一侧的像素界定层6；设置在像素界定层6远离衬底基板1一侧的发光层42；以及设置在发光层42远离衬底基板1一侧的阴极43。
像素界定层6包括多个开口62。多个开口62分别位于多个子像素中，例如，每一个子像素中设置有一个开口62。每一个开口62暴露阳极41的一部分。发光层42的一部分填充于该开口62中，以与暴露的阳极41的部分接触。
图8A是根据本公开的一些示例性实施例的显示面板的位于第一显示区域中的一 个第一重复单元的平面示意图，图8B是根据本公开的一些示例性实施例的显示面板的位于第二显示区域中的一个第二重复单元的平面示意图。为了清楚地示出开口的形状和大小，图8A和图8B中仅示出了各个子像素的开口，而省略了其他结构。
如上所述，位于第一显示区域AA1和第二显示区域AA2中的子像素均具有开口，为了方便描述，将第一子像素SP1、第二子像素SP2、第三子像素SP3、第四子像素SP4、第五子像素SP5、第六子像素SP6、第七子像素SP7和第八子像素SP8具有的开口分别称为第一开口62A、第二开口62B、第三开口62C、第四开口62D、第五开口62E、第六开口62F、第七开口62G和第八开口62H。
参照图8A和图8B，在本公开的实施例中，第二开口62B在衬底基板1上的正投影的面积大于第一开口62A在衬底基板1上的正投影的面积。
这样，在本公开的实施例中，由于第二开口62B的面积大于第一开口62A的面积，所以，位于第二显示区域AA2中的子像素的实际发光面积大于位于第一显示区域AA1中具有相同颜色的子像素的实际发光面积。进一步地，由于子像素的实际发光面积决定了该子像素的发光亮度，所以，位于第二显示区域AA2中的子像素的发光亮度大于位于第一显示区域AA1中具有相同颜色的子像素的发光亮度。考虑到第一显示区域AA1的像素密度大于第二显示区域AA2的像素密度，在本公开的实施例中，通过使得位于第二显示区域AA2中的子像素的实际发光面积大于位于第一显示区域AA1中具有相同颜色的子像素的实际发光面积，提高了第一显示区域AA1中的各个重复单元的发光亮度与第二显示区域AA2中的各个重复单元的发光亮度的均一性，从而提高了显示均一性。
另外，在本公开的实施例中，通过增大实际发光面积的方式，来提高位于第二显示区域AA2中的子像素的发光亮度，所以，不需要采用其他方式(例如增加驱动电流)来提高位于第二显示区域AA2中的子像素的发光亮度，从而有利于提高位于第二显示区域AA2中的各个子像素的发光材料的寿命。以此方式，使得位于第二显示区域AA2中的各个子像素的发光材料的寿命与位于第一显示区域AA1中的各个子像素的发光材料的寿命的均一性得到提高。
继续参照图8A和图8B，在本公开的实施例中，第四开口62D在衬底基板1上的正投影的面积大于第三开口62C在衬底基板1上的正投影的面积。
第六开口62F和第八开口62H在衬底基板1上的正投影的面积之和大于第五开口 62E和第七开口62G在衬底基板1上的正投影的面积之和。通过这样的方式，可以进一步提高第一显示区域和第二显示区域之间的显示均一性，并提高位于第一显示区域和第二显示区域中的各个子像素的发光材料的寿命的均一性。
继续参照图8A和图8B，第一开口62A、第二开口62B、第三开口62C和第四开口62D中的每一个在衬底基板1上的正投影具有六边形的形状。
具体地，每一个六边形包括彼此间隔且平行设置3组对边，即，每一个六边形包括6条边，分别为图中的sl1、sl2、sl3、sl4、sl5和sl6，其中，边sl1与边sl2彼此间隔且平行，边sl3与边sl4彼此间隔且平行，边sl5与边sl6彼此间隔且平行。边sl1与边sl2沿列方向Y延伸，边sl3与边sl5相交于一个顶点o1，边sl4与边sl6相交于一个顶点o2。
在图8A中，边sl1与边sl2之间的垂直距离(可以称为第一宽度)为W1，顶点o1与顶点o2之间的距离(可以称为第一长度)为L1。那么，第一开口62A在衬底基板1上的正投影的面积S 62A可以用以下公式计算：
Figure PCTCN2020088328-appb-000002
在图8B中，边sl1与边sl2之间的垂直距离(可以称为第二宽度)为W2，顶点o1与顶点o2之间的距离(可以称为第二长度)为L2。那么，第二开口62B在衬底基板1上的正投影的面积S 62B可以用以下公式计算：
Figure PCTCN2020088328-appb-000003
需要说明的是，上述W1和W2可以视为在行方向X上的第一尺寸，上述L1和L2可以视为在列方向Y上的第二尺寸。
示例性地，第二宽度W2可以大于第一宽度W1，和/或，第二长度L2可以大于第一长度L1。
在一些示例性的实施例中，第二宽度W2可以等于(1+n)W1，第二长度L2可以等于(1+n)L1，其中，n为大于0的数。这样，第二开口62B的面积为第一开口62A的面积的(1+n) 2倍。
同样地，n可以等于约9％，即，第二宽度W2相对于第一宽度W1增加约9％，第二长度L2相对于第一长度L1增加约9％。这样，第二开口62B的面积为第一开口 62A的面积的约1.19倍。
可选地，所述第四开口62D的第一尺寸W4大于所述第三开口62C的第一尺寸W3，所述第四开口62D的第二尺寸L4大于所述第三开口62C的第二尺寸L3。
例如，在图8A和图8B所示的实施例中，对于具有第一颜色的第一子像素SP1和第二子像素而言，W2可以等于(1+n 1)W1，L2可以等于(1+n 1)L1，其中，n 1为大于0的数。这样，第二开口62B的面积为第一开口62A的面积的(1+n 1) 2倍。对于具有第二颜色的第三子像素SP3和第四子像素SP4而言，W4可以等于(1+n 2)W3，L4可以等于(1+n 2)L3，其中，n 2为大于0的数。这样，第二开口62B的面积为第一开口62A的面积的(1+n 2) 2倍。
例如，n 1和n 2可以彼此相等。也就是说，不同颜色的子像素的外扩系数可以设置为彼此相同。例如，它们都可以小于等于约9％。
可选地，n 1和n 2可以彼此不相等。也就是说，不同颜色的子像素的外扩系数可以设置为彼此不同。
继续参照图8A和图8B，第五子像素SP5、第六子像素SP6、第七子像素SP7和第八子像素SP8中的每一个在衬底基板1上的正投影可以具有五边形的形状。每一个五边形可以包括5条边，分别为图中的l1、l2、l3、l4和l5，其中，边l1与边l2彼此间隔且平行，边l3的一端与边l1相交，边l3的另一端与边l2相交，边l4与边l5相交于一个顶点o3，顶点o3与边l3相对。
例如，在每一个重复单元中，存在沿行方向X延伸的一条对称轴AX，第五子像素SP5和第七子像素SP7关于该对称轴AX对称，并且，第六子像素SP6和第八子像素SP8关于该对称轴AX对称。应该理解，对称轴AX是一条假想的轴线，并不是显示面板的实际结构。
在图8A中，边l1与边l2之间的垂直距离(可以称为在行方向X上的第一尺寸)为W5和W7，顶点o3与边l3之间的垂直距离(可以称为在列方向Y上的第二尺寸)为L5和L7。在图8B中，边l1与边l2之间的垂直距离(可以称为在行方向X上的第一尺寸)为W6和W8，顶点o3与边l3之间的垂直距离(可以称为在列方向Y上的第二尺寸)为L6和L8。
类似地，在一些示例性的实施例中，W6可以等于(1+n 3)W5，L6可以等于(1+n 3) L5，W8可以等于(1+n 3)W7，L8可以等于(1+n 3)L7，其中，n 3为大于0的数。这样，图8B中示出的第六子像素SP6的第六开口62F和第八子像素SP8的第八开口62H的面积之和为图8A中示出的第五子像素SP5的第五开口62E和第七子像素SP7的第七开口62G的面积之和的(1+n 3) 2倍。
类似地，例如，n 3可以等于约9％，即，W6相对于W5增加约9％，L6相对于L5增加约9％。这样，图8B中示出的第六子像素SP6的第六开口62F和第八子像素SP8的第八开口62H的面积之和为图8A中示出的第五子像素SP5的第五开口62E和第七子像素SP7的第七开口62G的面积之和的约1.19倍。以此方式，可以在避免产生混色的情况下尽量提高第一显示区域和第二显示区域之间的显示均一性和发光材料寿命的均一性。
可选地，n 1、n 2和n 3可以彼此相等。也就是说，不同颜色的子像素的外扩系数可以设置为彼此相同。例如，它们都可以等于约9％。
可选地，n 1、n 2和n 3可以彼此不相等。也就是说，不同颜色的子像素的外扩系数可以设置为彼此不同。可选地，n 1、n 2和n 3中的2个可以彼此相等。
同样地，在本公开的一些实施例中，上述的外扩系数n 1、n 2和n 3可以大于0小于30％，例如，可以为5％，10％，15％，20％等。
在本公开的实施例中，第二重复单元P2中相邻的两个子像素之间的开口62之间间隔的距离d在4微米以上，即，在一个所述第二重复单元中，相邻的两个子像素的开口的边缘之间的最小距离在4微米以上。例如，在4～20微米之间。当第二重复单元P2中相邻的两个子像素之间的开口62之间间隔的距离d小于4微米时，相邻的两个子像素之间混色的风险较高。相应地，第一重复单元P1中相邻的两个子像素之间的开口62之间间隔的距离d比第二重复单元P2中相邻的两个子像素之间的开口62之间间隔的距离d至少大3微米。
图9是根据本公开的一些示例性实施例的显示面板的平面示意图。图10A是根据本公开的一些示例性实施例的显示面板的位于第一显示区域中的一个第一重复单元的平面示意图，图10B是根据本公开的一些示例性实施例的显示面板的位于第二显示区域中的一个第二重复单元的平面示意图。为了清楚地示出开口的形状和大小，图10A和图10B中仅示出了各个子像素的开口，而省略了其他结构。
下面将结合图9、图10A和图10B描述本实施例的特别之处，应该理解，本实施 例的其他结构和特点，可以参照上文的描述。
参照图9，所述显示面板包括沿行方向X和列方向Y成阵列排列的多个重复单元。其中，一些重复单元P1(即第一重复单元)位于第一显示区域AA1，另一些重复单元P2(即第二重复单元)位于第二显示区域AA2。
每一个重复单元可以包括4个子像素。具体地，第一重复单元P1可以包括第一子像素SP1、第三子像素SP3、第五子像素SP5和第七子像素SP7，第二重复单元P2可以包括第二子像素SP2、第四子像素SP4、第六子像素SP6和第八子像素SP8。
例如，第五子像素SP5和第七子像素SP7以及第六子像素SP6和第八子像素SP8可为人眼敏感颜色的子像素，例如可为绿色子像素、黄色子像素、白色子像素等。例如，相比于第一子像素SP1至第四子像素SP4，第五子像素SP5和第七子像素SP7以及第六子像素SP6和第八子像素SP8每一个的面积相对较小。
第一子像素SP1、第二子像素SP2、第三子像素SP3和第四子像素SP4可为人眼不敏感颜色的子像素。例如，第一子像素SP1和第二子像素SP2为红色子像素，第三子像素SP3和第四子像素SP4为蓝色子像素，但本公开的实施例不限于此。在本公开的一些示例性实施例中，以第一子像素SP1和第二子像素SP2为红色子像素，第三子像素SP3和第四子像素SP4为蓝色子像素为例进行说明。需要说明的是，当像素排列结构采用红绿蓝(RGB)模式时，上述的人眼敏感颜色可为绿色。
在根据本公开的实施例中，通过这样排列各个子像素，可以提高像素排列结构视觉上的分辨率，从而提高显示质量。
如上所述，位于第一显示区域AA1和第二显示区域AA2中的子像素均具有开口，为了方便描述，将第一子像素SP1、第二子像素SP2、第三子像素SP3、第四子像素SP4、第五子像素SP5、第六子像素SP6、第七子像素SP7和第八子像素SP8具有的开口分别称为第一开口62A、第二开口62B、第三开口62C、第四开口62D、第五开口62E、第六开口62F、第七开口62G和第八开口62H。
参照图9，多个第一重复单元P1沿行方向X和列方向Y成阵列地排列，多个第二重复单元P2沿行方向X和列方向Y成阵列地排列。第一重复单元P1的分布密度大于第二重复单元P2的分布密度。
对于一个第二重复单元P2而言，其包括的第六子像素SP6和第八子像素SP8位于同一列，且沿列方向Y设置在第四子像素SP4的两侧。第二子像素SP2、第四子像 素SP4以及第六/八子像素SP6/SP8分别位于三列，即，第二子像素SP2、第四子像素SP4以及第六/八子像素SP6/SP8沿行方向X依次排列。第二子像素SP2和第六子像素SP6位于同一行。第二/六子像素SP2/SP6、第四子像素SP4以及第八子像素SP8沿列方向Y依次排列。
第二重复单元P2与一些第一重复单元P1在列方向Y上对齐。例如，第二重复单元P2仅与奇数列的第一重复单元P1在列方向Y上对齐，在偶数列的第一重复单元P1所在的列中，不设置所述第二重复单元P2。当然，也可以说，第二重复单元P2仅与偶数列的第一重复单元P1在列方向Y上对齐，在奇数列的第一重复单元P1所在的列中，不设置所述第二重复单元P2。具体地，在相邻的两行第二重复单元P2中，位于其中一行中的一个第二重复单元P2与位于另一行中的与该第二重复单元P2相邻的一个第二重复单元P2在行方向X上间隔设置，间隔的距离基本等于一个第一重复单元沿行方向X的尺寸(即宽度)。
继续参照图9，在同一行的第二重复单元P2中，相邻的两个第二重复单元P2在行方向X上间隔设置，间隔的距离基本等于三个第一重复单元沿行方向X的尺寸。
多个第一重复单元P1沿行方向X和列方向Y成阵列地排列，多个第二重复单元P2沿行方向X和列方向Y成阵列地排列。相应地，每一个重复单元P1、P2所包括的子像素也沿行方向X和列方向Y成阵列地排列。在同一列的重复单元P1、P2中，第一子像素SP1和第二子像素SP2位于同一列，第三子像素SP3和第四子像素SP4位于同一列，第五子像素SP5和第七子像素SP7以及第六子像素SP6和第八子像素SP8位于同一列。
例如，在第一显示区域AA1中，第一重复单元P1包括的第一子像素SP1沿行方向X和列方向Y成阵列地排列。在同一行的第一重复单元P1中，两个相邻的第一子像素SP1之间间隔两列子像素，即，间隔一列第三子像素SP3和一列第五/第七子像素SP5/SP7。
例如，在第二显示区域AA2中，第二重复单元P2包括的第二子像素SP2沿行方向X和列方向Y成阵列地排列。在同一行的第二重复单元P2中，两个相邻的第二子像素SP2之间间隔十一列子像素，即，依次间隔一列第四子像素SP4、一列第六/第八子像素SP6/SP8、一列第一子像素SP1、一列第三子像素SP3、一列第五/第七子像素SP5/SP7、一列第一子像素SP1、一列第三子像素SP3、一列第五/第七子像素SP5/SP7、 一列第一子像素SP1、一列第三子像素SP3和一列第五/第七子像素SP5/SP7。
继续参照图9，所述显示面板还包括多个隔垫物。为了描述方便，将位于第一显示区域AA1中的隔垫物描述为第一隔垫物PS1，将位于第二显示区域AA2中的隔垫物描述为第二隔垫物PS2。
多个第一隔垫物PS1沿行方向X和列方向Y成阵列地排列于第一显示区域AA1中，多个第二隔垫物PS2沿行方向X和列方向Y成阵列地排列于第二显示区域AA2中。第一隔垫物PS1的分布密度大于第二隔垫物PS2的分布密度。例如，第二隔垫物PS2的分布密度可以为第一隔垫物PS1的分布密度的大约1/6至1/3。例如，如图9所述，第二隔垫物PS2的分布密度可以为第一隔垫物PS1的分布密度的大约1/4。
第二隔垫物PS2仅设置于第二重复单元P2所在的区域中，即，在没有第二重复单元P2的透光区域TRA中，不设置第二隔垫物PS2。
例如，第二隔垫物PS2的数量不大于第二重复单元P2的数量。
可选地，第二隔垫物PS2的数量可以等于第二重复单元P2的数量，例如，每一个第二重复单元P2中设置一个且仅设置一个第二隔垫物PS2。可选地，如图9所示，第二隔垫物PS2的数量可以小于第二重复单元P2的数量，例如，一些第二重复单元P2中设置一个且仅设置一个第二隔垫物PS2，另一些第二重复单元P2中不设置第二隔垫物PS2。
继续参照图9，在第二显示区域AA2中，一些第二隔垫物PS2设置在第二子像素SP2与第六子像素SP6之间。为了描述方便，将设置在第二子像素SP2与第六子像素SP6之间的第二隔垫物PS2称为第一子隔垫物PS21。对于位于同一列的多个第一子隔垫物PS21而言，这些第一子隔垫物PS21的连线穿过第四子像素SP4，即，它们在列方向Y上与第四子像素SP4对齐。
在第二显示区域AA2中，另一些第二隔垫物PS2设置在第四子像素SP4的一侧，且在列方向Y上与第二子像素SP2对齐。为了描述方便，将设置在第四子像素SP4的一侧第二隔垫物PS2称为第二子隔垫物PS22。对于位于同一列的多个第二子隔垫物PS22而言，这些第二子隔垫物PS22的连线穿过第二子像素SP2。
如果将图9中的XY坐标系逆时针旋转45°，即列方向Y沿相对于水平线45°的左上方延伸，行方向X沿相对于水平线45°的右上方延伸，此时，位于同一列的第二隔垫物的类型相同，即，在同一列的隔垫物中，均为第一子隔垫物PS21或第二子隔 垫物PS22。在相邻的两列隔垫物中，第二隔垫物的类型不同，即在相邻的两列隔垫物中，其中一列为第一子隔垫物PS21，另一列为第二子隔垫物PS22。也就是说，在相对于列方向Y成一定倾斜角(例如45°)的斜列方向(如图9中的方向Y1所示)上，位于同一斜列的第二隔垫物均为第一子隔垫物PS21或第二子隔垫物PS22，位于相邻两个斜列的第二隔垫物中，其中一列为第一子隔垫物PS21，另一列为第二子隔垫物PS22。
参照图10A和图10B，在本公开的实施例中，第二开口62B在衬底基板1上的正投影的面积大于第一开口62A在衬底基板1上的正投影的面积。
第四开口62D在衬底基板1上的正投影的面积大于第三开口62C在衬底基板1上的正投影的面积。
第六开口62F和第八开口62H在衬底基板1上的正投影的面积之和大于第五开口62E和第七开口62G在衬底基板1上的正投影的面积之和。例如，第六开口62F在衬底基板1上的正投影的面积大于第五开口62E在衬底基板1上的正投影的面积，并且，第八开口62H在衬底基板1上的正投影的面积大于第七开口62G在衬底基板1上的正投影的面积。
也就是说，第二重复单元P2中的各个子像素的开口相对于第一重复单元P1中对应的各个子像素的开口外扩。关于外扩的详细描述，可以参照上文结合图1至图8B的描述，在此不再赘述。
通过这样的方式，可以进一步提高第一显示区域和第二显示区域之间的显示均一性，并提高位于第一显示区域和第二显示区域中的各个子像素的发光材料的寿命的均一性。
图11是根据本公开的一些示例性实施例的显示面板的平面示意图。图12A是根据本公开的一些示例性实施例的显示面板的位于第一显示区域中的一个第一重复单元的平面示意图，图12B是根据本公开的一些示例性实施例的显示面板的位于第二显示区域中的一个第二重复单元的平面示意图。为了清楚地示出开口的形状和大小，图12A和图12B中仅示出了各个子像素的开口，而省略了其他结构。
下面将结合图11、图12A和图12B描述本实施例的特别之处，应该理解，本实施例的其他结构和特点，可以参照上文的描述。
参照图11，所述显示面板包括沿行方向X和列方向Y成阵列排列的多个重复单元。 其中，一些重复单元P1(即第一重复单元)位于第一显示区域AA1，另一些重复单元P2(即第二重复单元)位于第二显示区域AA2。
每一个重复单元可以包括4个子像素。具体地，第一重复单元P1可以包括第一子像素SP1、第三子像素SP3、第五子像素SP5和第七子像素SP7，第二重复单元P2可以包括第二子像素SP2、第四子像素SP4、第六子像素SP6和第八子像素SP8。
参照图11，多个第一重复单元P1沿行方向X和列方向Y成阵列地排列，多个第二重复单元P2沿行方向X和列方向Y成阵列地排列。第一重复单元P1的分布密度大于第二重复单元P2的分布密度。
对于一个第二重复单元P2而言，其包括的第六子像素SP6和第八子像素SP8位于同一列，且沿列方向Y设置在第四子像素SP4的同一侧。第六子像素SP6和第八子像素SP8沿列方向Y间隔设置。第六子像素SP6和第八子像素SP8沿行方向X设置在第二子像素SP2的同一侧。第二子像素SP2、第四子像素SP4以及第六/八子像素SP6/SP8分别位于三列，即，第二子像素SP2、第四子像素SP4以及第六/八子像素SP6/SP8沿行方向X依次排列。第六子像素SP6和第八子像素SP8的组合与第二子像素SP2位于同一行。第四子像素SP4以及第二/六/八子像素SP2/SP6/SP8沿列方向Y依次排列。
第二重复单元P2与一些第一重复单元P1在列方向Y上对齐。例如，第二重复单元P2仅与奇数列的第一重复单元P1在列方向Y上对齐，在偶数列的第一重复单元P1所在的列中，不设置所述第二重复单元P2。当然，也可以说，第二重复单元P2仅与偶数列的第一重复单元P1在列方向Y上对齐，在奇数列的第一重复单元P1所在的列中，不设置所述第二重复单元P2。具体地，在相邻的两行第二重复单元P2中，位于其中一行中的一个第二重复单元P2与位于另一行中的与该第二重复单元P2相邻的一个第二重复单元P2在行方向X上间隔一个重复单元。
继续参照图11，在同一行的第二重复单元P2中，相邻的两个第二重复单元P2在行方向X上间隔三个重复单元。
多个第一重复单元P1沿行方向X和列方向Y成阵列地排列，多个第二重复单元P2沿行方向X和列方向Y成阵列地排列。相应地，每一个重复单元P1、P2所包括的子像素也沿行方向X和列方向Y成阵列地排列。在同一列的重复单元P1、P2中，第一子像素SP1和第二子像素SP2位于同一列，第三子像素SP3和第四子像素SP4位于 同一列，第五子像素SP5和第七子像素SP7以及第六子像素SP6和第八子像素SP8位于同一列。
例如，在第一显示区域AA1中，第一重复单元P1包括的第一子像素SP1沿行方向X和列方向Y成阵列地排列。在同一行的第一重复单元P1中，两个相邻的第一子像素SP1之间间隔两列子像素，即，间隔一列第三子像素SP3和一列第五/第七子像素SP5/SP7。
例如，在第二显示区域AA2中，第二重复单元P2包括的第二子像素SP2沿行方向X和列方向Y成阵列地排列。在同一行的第二重复单元P2中，两个相邻的第二子像素SP2之间间隔十一列子像素，即，依次间隔一列第四子像素SP4、一列第六/第八子像素SP6/SP8、一列第一子像素SP1、一列第三子像素SP3、一列第五/第七子像素SP5/SP7、一列第一子像素SP1、一列第三子像素SP3、一列第五/第七子像素SP5/SP7、一列第一子像素SP1、一列第三子像素SP3和一列第五/第七子像素SP5/SP7。
继续参照图11，所述显示面板还包括多个隔垫物。为了描述方便，将位于第一显示区域AA1中的隔垫物描述为第一隔垫物PS1，将位于第二显示区域AA2中的隔垫物描述为第二隔垫物PS2。
多个第一隔垫物PS1沿行方向X和列方向Y成阵列地排列于第一显示区域AA1中，多个第二隔垫物PS2沿行方向X和列方向Y成阵列地排列于第二显示区域AA2中。第一隔垫物PS1的分布密度大于第二隔垫物PS2的分布密度。例如，第二隔垫物PS2的分布密度可以为第一隔垫物PS1的分布密度的大约1/6至1/3。例如，如图11所述，第二隔垫物PS2的分布密度可以为第一隔垫物PS1的分布密度的大约1/3。
第二隔垫物PS2仅设置于第二重复单元P2所在的区域中，即，在没有第二重复单元P2的透光区域TRA中，不设置第二隔垫物PS2。
例如，第二隔垫物PS2的数量不大于第二重复单元P2的数量。
可选地，第二隔垫物PS2的数量可以等于第二重复单元P2的数量，例如，每一个第二重复单元P2中设置一个且仅设置一个第二隔垫物PS2。可选地，如图11所示，第二隔垫物PS2的数量可以小于第二重复单元P2的数量，例如，一些第二重复单元P2中设置一个且仅设置一个第二隔垫物PS2，另一些第二重复单元P2中不设置第二隔垫物PS2。
继续参照图11，在第二显示区域AA2中，一些第二隔垫物PS2设置在第六子像 素SP6和第八子像素SP8的组合与第二子像素SP2之间。为了描述方便，将这些第二隔垫物PS2称为第一子隔垫物PS21。对于位于同一列的多个第一子隔垫物PS21而言，这些第一子隔垫物PS21的连线穿过第四子像素SP4，即，它们在列方向Y上与第四子像素SP4对齐。
在第二显示区域AA2中，另一些第二隔垫物PS2设置在第四子像素SP4的一侧，且在列方向Y上与第六子像素SP6和第八子像素SP8的组合对齐。为了描述方便，将这些第二隔垫物称为第二子隔垫物PS22。对于位于同一列的多个第二子隔垫物PS22而言，这些第二子隔垫物PS22的连线穿过第六子像素SP6和第八子像素SP8。
同样地，如果将图11中的XY坐标系逆时针旋转45°，即列方向Y沿相对于水平线45°的左上方延伸，行方向X沿相对于水平线45°的右上方延伸，此时，位于同一列的第二隔垫物的类型相同，即，在同一列的隔垫物中，均为第一子隔垫物PS21或第二子隔垫物PS22。在相邻的两列隔垫物中，第二隔垫物的类型不同，即在相邻的两列隔垫物中，其中一列为第一子隔垫物PS21，另一列为第二子隔垫物PS22。也就是说，在相对于列方向Y成一定倾斜角(例如45°)的斜列方向(如图11中的方向Y1所示)上，位于同一斜列的第二隔垫物均为第一子隔垫物PS21或第二子隔垫物PS22，位于相邻两个斜列的第二隔垫物中，其中一列为第一子隔垫物PS21，另一列为第二子隔垫物PS22。
参照图12A和图12B，在本公开的实施例中，第二开口62B在衬底基板1上的正投影的面积大于第一开口62A在衬底基板1上的正投影的面积。
第四开口62D在衬底基板1上的正投影的面积大于第三开口62C在衬底基板1上的正投影的面积。
第六开口62F和第八开口62H在衬底基板1上的正投影的面积之和大于第五开口62E和第七开口62G在衬底基板1上的正投影的面积之和。例如，第六开口62F在衬底基板1上的正投影的面积大于第五开口62E在衬底基板1上的正投影的面积，并且，第八开口62H在衬底基板1上的正投影的面积大于第七开口62G在衬底基板1上的正投影的面积。
也就是说，第二重复单元P2中的各个子像素的开口相对于第一重复单元P1中对应的各个子像素的开口外扩。关于外扩的详细描述，可以参照上文结合图1至图8B的描述，在此不再赘述。
通过这样的方式，可以进一步提高第一显示区域和第二显示区域之间的显示均一性，并提高位于第一显示区域和第二显示区域中的各个子像素的发光材料的寿命的均一性。
图13是根据本公开的一些示例性实施例的显示面板的平面示意图。图14A是根据本公开的一些示例性实施例的显示面板的位于第一显示区域中的一个第一重复单元的平面示意图，图14B是根据本公开的一些示例性实施例的显示面板的位于第二显示区域中的一个第二重复单元的平面示意图。为了清楚地示出开口的形状和大小，图14A和图14B中仅示出了各个子像素的开口，而省略了其他结构。
下面将结合图13、图14A和图14B描述本实施例的特别之处，应该理解，本实施例的其他结构和特点，可以参照上文的描述。
参照图13，所述显示面板包括沿行方向X和列方向Y成阵列排列的多个重复单元。其中，一些重复单元P1(即第一重复单元)位于第一显示区域AA1，另一些重复单元P2(即第二重复单元)位于第二显示区域AA2。
一些第一重复单元P1可以包括4个子像素，即第一子像素SP1、第三子像素SP3、第五子像素SP5和第七子像素SP7。第二重复单元P2可以包括3个子像素，即第二子像素SP2、第四子像素SP4和第六子像素SP6。
可选地，对于靠近第二显示区域AA2边缘设置的多个第一重复单元P1而言，例如，参照图13，对于靠近第二显示区域AA2下边缘的一行第一重复单元P1而言，每一个第一重复单元P1可以包括3个子像素，即第一子像素SP1、第三子像素SP3和第五子像素SP5。即，在这一行第一重复单元P1中，每一个第一重复单元P1均不包括上述第七子像素SP7。第五子像素SP5相对于第一子像素SP1或第三子像素SP3更远离与该行第一重复单元P1相邻的一行第二重复单元P2，即，第五子像素SP5与相邻的一行第二重复单元P2沿列方向Y之间的距离大于第一子像素SP1或第三子像素SP3与相邻的一行第二重复单元P2沿列方向Y之间的距离。这样，在靠近第二显示区域AA2下边缘的一行第一重复单元P1中，在每个第五子像素SP5处形成凹入的结构。通过这样的方式，可以增大第五子像素SP5与相邻的一行第二重复单元P2之间的距离，从而可以增大透光区域TRA的面积，增大透过率。
参照图13，多个第一重复单元P1沿行方向X和列方向Y成阵列地排列，多个第二重复单元P2沿行方向X和列方向Y成阵列地排列。第一重复单元P1的分布密度大 于第二重复单元P2的分布密度。
对于一个第二重复单元P2而言，其包括的第二子像素SP2、第六子像素SP6和第四子像素SP4位于同一行，且沿行方向X按照上述顺序依次排列。
两行相邻的第二重复单元P2之间存在一个空白的行，即该行不设置第二重复单元P2。也就是说，两行相邻的第二重复单元P2之间的间隔距离等于一个第二重复单元P2沿列方向Y的尺寸。通过这样的方式，可以增加透光区域TRA的面积。
继续参照图13，所述显示面板还包括多个隔垫物。为了描述方便，将位于第一显示区域AA1中的隔垫物描述为第一隔垫物PS1，将位于第二显示区域AA2中的隔垫物描述为第二隔垫物PS2。
多个第一隔垫物PS1沿行方向X和列方向Y成阵列地排列于第一显示区域AA1中，多个第二隔垫物PS2沿行方向X和列方向Y成阵列地排列于第二显示区域AA2中。第一隔垫物PS1的分布密度大于第二隔垫物PS2的分布密度。例如，第二隔垫物PS2的分布密度可以为第一隔垫物PS1的分布密度的大约1/4至1/2。例如，如图13所述，第二隔垫物PS2的分布密度可以为第一隔垫物PS1的分布密度的大约1/2。
第二隔垫物PS2仅设置于第二重复单元P2所在的区域中，即，在没有第二重复单元P2的透光区域TRA中，不设置第二隔垫物PS2。
例如，第二隔垫物PS2的数量不大于第二重复单元P2的数量。
可选地，第二隔垫物PS2的数量可以等于第二重复单元P2的数量，例如，每一个第二重复单元P2中设置一个且仅设置一个第二隔垫物PS2。可选地，如图13所示，第二隔垫物PS2的数量可以小于第二重复单元P2的数量，例如，一些第二重复单元P2中设置一个且仅设置一个第二隔垫物PS2，另一些第二重复单元P2中不设置第二隔垫物PS2。
参照图14A和图14B，在本公开的实施例中，第二开口62B在衬底基板1上的正投影的面积大于第一开口62A在衬底基板1上的正投影的面积。
第四开口62D在衬底基板1上的正投影的面积大于第三开口62C在衬底基板1上的正投影的面积。
也就是说，第二重复单元P2中的各个子像素的开口相对于第一重复单元P1中对应的各个子像素的开口外扩。关于外扩的详细描述，可以参照上文结合图1至图8B的描述，在此不再赘述。
结合参照图13、图14A和图14B，一个第一重复单元P1包括2个绿色子像素，即，第五子像素SP5和第七子像素SP7。第五子像素SP5的开口62E和第七子像素SP7的开口62G之间没有连通，通过一部分像素界定层隔开。一个第二重复单元P2包括1个绿色子像素，即第六子像素SP6。第六子像素SP6的开口62F可以认为是在开口62E和开口62G连通的基础上进行外扩。
如图14B所示，示出了第五子像素SP5的开口62E和第七子像素SP7的开口62G，并且还示出了像素界定层6位于开口62E和开口62G之间的部分65。第六子像素SP6的开口62F在衬底基板1上的面积大于第五子像素SP5的开口62E、第七子像素SP7的开口62G以及部分65的组合在衬底基板1上的面积。也就是说，第二重复单元P2中的第六子像素SP6的开口62F相对于第一重复单元P1中第五子像素SP5的开口62E、第七子像素SP7的开口62G以及部分65的组合进行了外扩。关于外扩的详细描述，可以参照上文结合图1至图8B的描述，在此不再赘述。
通过这样的方式，可以进一步提高第一显示区域和第二显示区域之间的显示均一性，并提高位于第一显示区域和第二显示区域中的各个子像素的发光材料的寿命的均一性。
图15是根据本公开的一些示例性实施例的显示面板的平面示意图。图16A是根据本公开的一些示例性实施例的显示面板的位于第一显示区域中的一个第一重复单元的平面示意图，图16B是根据本公开的一些示例性实施例的显示面板的位于第二显示区域中的一个第二重复单元的平面示意图，图16C是根据本公开的一些示例性实施例的显示面板的位于第二显示区域中的一个第三重复单元的平面示意图。为了清楚地示出开口的形状和大小，图16A至图16C中仅示出了各个子像素的开口，而省略了其他结构。
下面将结合图15、图16A至图16C描述本实施例的特别之处，应该理解，本实施例的其他结构和特点，可以参照上文的描述。
参照图15，所述显示面板包括沿行方向X和列方向Y成阵列排列的多个重复单元。其中，一些重复单元P1(即第一重复单元)位于第一显示区域AA1，另一些重复单元(包括第二重复单元P2和第三重复单元P3)位于第二显示区域AA2。
第一重复单元P1可以包括第一子像素SP1、第三子像素SP3、第五子像素SP5和第七子像素SP7。第二重复单元P2可以包括第二子像素SP2和第六子像素SP6，第三 重复单元可以包括第四子像素SP4和第八子像素SP8。
参照图15，多个第一重复单元P1沿行方向X和列方向Y成阵列地排列，多个第二重复单元P2沿行方向X和列方向Y成阵列地排列，多个第三重复单元P3沿行方向X和列方向Y成阵列地排列。第一重复单元P1的分布密度大于第二重复单元P2的分布密度，并且第一重复单元P1的分布密度大于第三重复单元P3的分布密度。
第二重复单元P2所在的行和第三重复单元P3所在的行沿列方向Y交替设置。第二重复单元P2所在的列与第三重复单元P3所在的列沿行方向X间隔设置，间隔的距离基本等于一个第一重复单元P1沿行方向X的尺寸。
对于一个第二重复单元P2而言，其包括的第二子像素SP2和第六子像素SP6分别位于2个相邻的子像素列。对于一个第三重复单元P3而言，其包括的第四子像素SP4和第八子像素SP8分别位于2个相邻的子像素列。
第二重复单元P2的第二子像素SP2与一部分第一重复单元P1的第一子像素SP1位于同一列。第二重复单元P2的第六子像素SP6与一部分第一重复单元P1的第五子像素SP5和第七子像素SP7位于同一列。第三重复单元P2的第四子像素SP4与一部分第一重复单元P1的第三子像素SP3位于同一列。第三重复单元P3的第八子像素SP8与一部分第一重复单元P1的第五子像素SP5和第七子像素SP7位于同一列。
继续参照图15，所述显示面板还包括多个隔垫物。为了描述方便，将位于第一显示区域AA1中的隔垫物描述为第一隔垫物PS1，将位于第二显示区域AA2中的隔垫物描述为第二隔垫物PS2。
多个第一隔垫物PS1沿行方向X和列方向Y成阵列地排列于第一显示区域AA1中，多个第二隔垫物PS2沿行方向X和列方向Y成阵列地排列于第二显示区域AA2中。第一隔垫物PS1的分布密度大于第二隔垫物PS2的分布密度。例如，第二隔垫物PS2的分布密度可以为第一隔垫物PS1的分布密度的大约1/6至1/3。例如，如图15所述，第二隔垫物PS2的分布密度可以为第一隔垫物PS1的分布密度的大约1/6。
第二隔垫物PS2仅设置于第二重复单元P2所在的区域中，即，在没有第二重复单元P2的透光区域TRA中，不设置第二隔垫物PS2。
例如，第二隔垫物PS2的数量不大于第二重复单元P2的数量。
可选地，第二隔垫物PS2的数量可以等于第二重复单元P2的数量，例如，每一个第二重复单元P2中设置一个且仅设置一个第二隔垫物PS2。可选地，如图15所示， 第二隔垫物PS2的数量可以小于第二重复单元P2的数量，例如，一些第二重复单元P2中设置一个且仅设置一个第二隔垫物PS2，另一些第二重复单元P2中不设置第二隔垫物PS2。
参照图16A至图16C，在本公开的实施例中，第二开口62B在衬底基板1上的正投影的面积大于第一开口62A在衬底基板1上的正投影的面积。
第四开口62D在衬底基板1上的正投影的面积大于第三开口62C在衬底基板1上的正投影的面积。
第六开口62F在衬底基板1上的正投影的面积大于第五开口62E在衬底基板1上的正投影的面积。
第八开口62H在衬底基板1上的正投影的面积大于第七开口62G在衬底基板1上的正投影的面积。
也就是说，第二重复单元P2和第三重复单元P3中的各个子像素的开口相对于第一重复单元P1中对应的各个子像素的开口外扩。关于外扩的详细描述，可以参照上文结合图1至图8B的描述，在此不再赘述。
通过这样的方式，可以进一步提高第一显示区域和第二显示区域之间的显示均一性，并提高位于第一显示区域和第二显示区域中的各个子像素的发光材料的寿命的均一性。在上面的实施例中，分别以矩形、六边形和五边形为例，对各个子像素进行了描述，但是，本公开的实施例不限于这些形状，例如，子像素在衬底基板上的正投影的形状可以包括但不限于如下形状：梯形、菱形、圆形、椭圆形、近似矩形等，其中，近似矩形例如包括圆角矩形，但不限于此。相应地，每一个子像素的开口在衬底基板上的正投影的形状可以包括但不限于如下形状：矩形、六边形、五边形、梯形、菱形、圆形、椭圆形、近似矩形等。
需要说明的是，在上述实施例中，隔垫物在平面图中的形状示出为矩形形状，但是，本公开的实施例不局限于此，隔垫物在平面图中的形状还可以为其他形状，例如圆形、方形等。
返回参照图5，在本公开的一些示例性实施例中，上述像素界定层6可采用下述材料中的一种或多种制成：聚酰亚胺、硅氧化物、硅氮化物和光刻胶材料。例如，可以利用上述材料中的一种单独形成像素界定层6。可选地，像素界定层6可以由多层膜叠置构成，其中的每一层膜为上述的一种或多种材料形成。
参照图17，在本公开的一些示例性实施例中，可以采用如下的制造方法形成上述像素界定层6。
在步骤S101中，可以形成像素界定材料膜层。例如，可以采用涂敷、蒸镀、溅射、化学气相沉积等成膜方式形成像素界定材料膜层。
在步骤S102中，可以通过构图工艺，形成具有开口62的像素界定层6。
例如，在该构图工艺中，可以涂敷光刻胶，然后进行曝光和显影，曝光区域与待形成开口62的位置对应。然后，进行干刻去除曝光处的像素界定材料，形成开口62。最后，剥离剩余光刻胶。
可选地，如果像素界定层采用光刻胶材料构成时，在该步骤中，也可以选择不进行干刻。
返回参照图1和图2，本公开的至少一些实施例还提供一种显示装置。该显示装置可以包括如上所述的显示面板和图像传感器2(例如摄像头)。
如上所述，该显示面板具有第一显示区域和第二显示区域，该第一显示区域的像素密度大于该第二显示区域的像素密度。图像传感器2位于衬底基板1背离像素阵列的一侧，该图像传感器2的感光面朝向显示面板。图像传感器2在衬底基板1的正投影与第二显示区域AA2在所述衬底基板1上的正投影彼此交叠，例如，位于第二显示区域AA2在衬底基板1上的正投影内，由此可以利用通过第二显示区域的光进行成像，由此实现屏下摄像头功能。
图像传感器2可以采用本领域已知的结构，例如包括互补金属氧化物半导体(CMOS)图像传感器或者电荷耦合器件(CCD)图像传感器。图像传感器2可以电连接到图像处理器。除了图像传感器之外，为了实现更好的成像效果，包括该图像传感器的成像模组例如还可以包括镜头组件，镜头组件和图像传感器可以在垂直于衬底基板1的方向上依次沿着镜头组件的光轴排列设置。
所述显示装置可以包括任何具有显示功能的设备或产品。例如，所述显示装置可以是智能电话、移动电话、电子书阅读器、台式电脑(PC)、膝上型PC、上网本PC、个人数字助理(PDA)、便携式多媒体播放器(PMP)、数字音频播放器、移动医疗设备、相机、可穿戴设备(例如头戴式设备、电子服饰、电子手环、电子项链、电子配饰、电子纹身、或智能手表)、电视机等。
虽然本公开的总体技术构思的一些实施例已被显示和说明，本领域普通技术人员 将理解，在不背离所述总体技术构思的原则和精神的情况下，可对这些实施例做出改变，本公开的范围以权利要求和它们的等同物限定。
