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。
通常的OLED显示面板包括衬底基板、设置在衬底基板上的驱动电路、设置在驱动电路远离衬底基板的一侧的平坦层、设置在平坦层远离衬底基板一侧的阳极、设置在阳极远离衬底基板一侧的发光层以及设置在发光层远离衬底基板一侧的阴极。
衬底基板上的驱动电路通常包括使用源漏金属层制作的信号线，例如，用于传输或写入数据的数据线(Data line)和用于传输驱动电压的电源线(VDD line)。在驱动电路远离衬底基板的一侧制备阳极之前，需要在驱动电路上制备数据线(Data line)和一个电源线(VDD line)，之后制备绝缘层，在绝缘层上再制备另一电源线(VDD line)，然后在该另一电源线(VDD line)上制备平坦层(PLN)，之后在平坦层(PLN)上制备阳极，从而使得后续制备的阳极具有较高的平坦度。其中，使这两条电源线(VDD line)通过绝缘层中的过孔相互电连接，以降低电源线(VDD line)的电阻。然而，由于源漏金属层制作的信号线厚度较大，而源漏金属层制作的信号线上的平坦层无法使其完全平坦化，从而导致平坦层上的阳极和阳极上的发光层不平整，阳极和阳极上的发光层出现不对称凸起，从而导致从该显示面板的法线的左右两侧以与显示面板的法线呈相同的角度观察时会产生色偏现象。
图1为一些OLED显示面板的俯视结构示意图。图2为图一种OLED显示面板中一个子像素的剖面示意图。如图1和2所示，该OLED显示面板包括：衬底基板10、驱动电路20、平坦层30、阳极40、发光层50、阴极60以及像素限定层80；像素限定层80具有开口，以通过开口限定出有效发光区90。其中，例如，像素限定层80对蓝色子像素中的阳极41作用，以限定出蓝色有效发光区91，像素限定层80对红色子像素中的阳极42作用，以限定出红色有效发光区92，像素限定层80对绿色子像素中的阳极43作用，以限定出绿色有效发光区93。驱动电路20包括使用源漏金属层制作的另一电源线 25。图1示出另一电源线25和阳极40的位置关系。如图1与图2所示，由于另一电源线25厚度较大，覆盖另一电源线25的平坦层30无法使该显示面板完全平坦化，从而导致平坦层30上的阳极40和阳极40上的发光层50不平整，从而使得阳极40和阳极40上的发光层50出现不对称凸起70。该不对称凸起70是相对于阳极40沿另一电源线25的延伸方向上的对称轴不对称的，使得该不对称凸起70向该显示面板的法线的左右两侧发出的光不同，从而导致从该显示面板的法线的左右两侧以与显示面板的法线呈相同的角度观察时会产生色偏现象。例如，从该显示面板的法线的左侧以与显示面板的法线呈30度的角度观察该显示面板的颜色与从该显示面板的法线的右侧以与显示面板的法线呈30度的角度观察该显示面板的颜色不同，从而导致上述的色偏现象。
有鉴于此，本公开实施例提供电致发光显示面板及显示装置，其中，电致发光显示面板可以包括：多个重复单元，各重复单元包括多个子像素，各子像素包括：位于基板上方的第一导电层，位于第一导电层上方的第一绝缘层，位于第一绝缘层上的阳极。并且，第一绝缘层包括第一过孔，阳极包括相互电连接的主体部分和辅助部分。该第一过孔暴露第一导电层的一部分，并且辅助部分通过第一过孔与第一导电层电连接。多个重复单元中的至少一个包括：第一颜色子像素、第二颜色子像素以及第三颜色子像素；第三颜色子像素的主体部分的面积大于第二颜色子像素的主体部分的面积和第一颜色子像素的主体部分的面积；第三颜色子像素的主体部分与第一导电层交叠的面积大于第二颜色子像素的主体部分与第一导电层交叠的面积，且第三颜色子像素的主体部分与第一导电层交叠的面积大于第一颜色子像素的主体部分与第一导电层交叠的面积。这样至少可以消除中心区域的发光不对称性，从而可改善，甚至消除显示面板的色偏现象。
下面结合具体实施例，对本公开进行详细说明。需要说明的是，本实施例中是为了更好的解释本公开，但不限制本公开。
本公开实施例提供的一些电致发光显示面板，如图3至图8b所示，可以 包括：多个重复单元001，各重复单元001包括多个子像素，各子像素可以包括：位于基板100上方的第一导电层200，位于第一导电层200上方的第一绝缘层300，位于第一绝缘层300上的阳极400。并且，第一绝缘层300包括第一过孔310，阳极400包括相互电连接的主体部分410和辅助部分420。该第一过孔310暴露第一导电层200的一部分，并且辅助部分420通过第一过孔310与第一导电层200电连接。并且，多个重复单元中的至少一个可以包括：第一颜色子像素010、第二颜色子像素以及第三颜色子像素030；其中，第三颜色子像素030的主体部分413的面积大于第二颜色子像素的主体部分的面积和第一颜色子像素010的主体部分400的面积。第三颜色子像素030的主体部分413与第一导电层200交叠的面积大于第二颜色子像素的主体部分与第一导电层200交叠的面积，且第三颜色子像素030的主体部分413与第一导电层200交叠的面积大于第一颜色子像素010的主体部分411与第一导电层200交叠的面积。这样可以使第一导电层200具有镂空图案，与主体部分410在基板100的正投影交叠的镂空图案的部分被配置为使得主体部分410的至少中心区域AA大致平坦。
在具体实施时，在本公开实施例中，如图3a至图8c所示，同一子像素中的主体部分和辅助部分是一体结构。例如，采用一次构图工艺形成同一子像素中的主体部分和辅助部分。
需要说明的是，结合图3与图4a所示，第一导电层200中的阴影区域为限定出镂空图案的实体部分，由第一导电层200中的阴影区域围绕而成的空白部分形成了镂空图案。其中，与该实体部分在基板的正投影交叠的第一绝缘层300与该实体部分之间间隔有第一导电层，与该空白部分在基板的正投影交叠的第一绝缘层300直接设置在基板上，也可以说是与该空白部分在基板的正投影交叠的第一绝缘层300直接设置在基板上的绝缘层上。
在具体实施时，在本公开实施例中，如图3、图4a以及图5a所示，各子像素还可以包括位于阳极400背离基板100一侧的像素界定层80，位于阳极400背离基板100一侧的发光层50，以及位于阳极背离发光层50一侧的阴极 60。其中，像素限定层80具有开口，且开口暴露阳极400的主体部分410的至少部分区域，发光层50位于开口内且与开口暴露的主体部分410的区域接触，则开口中的发光层50所处于的区域用于发光，从而可以通过开口限定出有效发光区90。也就是说，像素限定层80的开口与阳极400的主体部分410交叠的部分区域为各子像素的有效发光区90。示例性地，第三颜色子像素030中的像素限定层80的开口与阳极400的主体部分413交叠的部分区域为第三颜色子像素030的有效发光区90-030。第一颜色子像素010中的像素限定层80的开口与阳极400的主体部分411交叠的部分区域为第一颜色子像素010的有效发光区90-010。第二颜色子像素021中的像素限定层80的开口与阳极400的主体部分4121交叠的部分区域为第二颜色子像素021的有效发光区90-021。第二颜色子像素022中的像素限定层80的开口与阳极400的主体部分4122交叠的部分区域为第二颜色子像素022的有效发光区90-022。
需要说明的是，在本公开的实施例中，每个发光层可以包括电致发光层本身以及位于电致发光层两侧的其他公共层，例如，空穴注入层、空穴传输层、电子注入层以及电子传输层等等，但是在本公开的附图中，仅示出了发光层中的电致发光层，而没有示出其他公共层。示例性地，电致发光层的材料可以包括：有机电致发光材料，这样可以使电致发光显示面板为OLED显示面板。或者，电致发光层的材料也可以包括：量子点电致发光材料，这样可以使电致发光显示面板为量子点发光二极管(Quantum Dot Light Emitting Diodes，QLED)显示面板。
需要说明的是，主体部分410的中心区域AA可以为由像素限定层的开口限定出的有效发光区。这样可以使整个有效发光区向主体部分410边缘形成过渡缓坡，以使有效发光区大概平坦，从而可改善，甚至消除显示面板的色偏现象。或者，主体部分410的中心区域AA小于由像素限定层限定出的有效发光区，例如主体部分410的中心区域AA可以为由像素限定层限定出的有效发光区的中心所在的区域。这样可以使主体部分410的中心区域AA向主体部分410边缘形成过渡缓坡，以使主体部分410的中心区域AA大概 平坦，从而可改善，甚至消除显示面板的色偏现象。
当然，与主体部分在基板的正投影交叠的镂空图案的部分被配置为使得主体部分大致平坦，这样可以使整个主体部分大改平坦，从而进一步改善，甚至消除显示面板的色偏现象。
在具体实施时，在本公开实施例中，如图3所示，第三颜色子像素030的主体部分413与第一导电层200交叠的面积大于第二颜色子像素的主体部分与第一导电层200交叠的面积与第一颜色子像素010的主体部分411与第一导电层200交叠的面积之和。
在具体实施时，在本公开实施例中，如图3与图4a所示，至少一个子像素中的主体部分400可以具有至少一个对称轴，并且主体部分400在基板100的正投影与第一导电层200在基板100的正投影交叠。并且，与至少一个子像素的主体部分400在基板100的正投影交叠的第一导电层200位于至少一个对称轴两侧的面积比值在1±0.1范围内。示例性地，与至少一个子像素的主体部分400在基板100的正投影交叠的第一导电层200位于至少一个对称轴两侧的面积比值可以为1.1。与至少一个子像素的主体部分400在基板100的正投影交叠的第一导电层200位于至少一个对称轴两侧的面积比值也可以为0.9。与至少一个子像素的主体部分400在基板100的正投影交叠的第一导电层200位于至少一个对称轴两侧的面积比值也可以为1.05或1。
在具体实施时，在本公开实施例中，如图3与图4a所示，与至少一个子像素的主体部分400在基板100的正投影交叠的第一导电层200沿至少一个对称轴大致呈轴对称。也就是说，与至少一个子像素的主体部分400在基板100的正投影交叠的第一导电层200位于至少一个对称轴两侧的面积比值大致为1。由于工艺条件限制，因此上述比值并不能绝对为1，因此大概满足上述条件即可。示例性地，如图3与图4a所示，以一个子像素中的主体部分413为例，主体部分413可以具有沿第一方向F1延伸的第一对称轴，与主体部分413在基板100的正投影交叠的第一导电层200可以沿该第一对称轴大致呈轴对称设置。和/或，主体部分413可以具有沿第二方向F2延伸的第二对称轴， 与主体部分413在基板100的正投影交叠的第一导电层200可以沿该第二对称轴大致呈轴对称设置。这样可以使至少主体部分413的中心区域AA具有凸起，第一对称轴两侧的主体部分413的区域对称设置和/或第二对称轴两侧的主体部分413的区域对称设置，，从而可以降低主体部分413的不对称性。从而可以改善有效发光区的发光不对称性，甚至消除有效发光区的发光不对称性，从而可改善，甚至消除显示面板的色偏现象。
在具体实施时，在本公开实施例中，如图3与图4a所示，第一导电层200可以包括：相互间隔设置的第一电源线210和第一连接线220；其中，各子像素中，辅助部分420通过第一过孔310与第一连接线220电连接。进一步地，第一电源线210可以被配置为传输驱动电压的电源线。需要说明的是，图3中仅示出了一个第三颜色子像素030中的第一连接线220，其余子像素中的第一连接线可以根据实际应用环境来设计确定，在此不作赘述。
一般在显示领域，一个像素通常包括多个可分别显示单色(例如红色、绿色或蓝色)的子像素，通过控制不同颜色的子像素的比例以实现显示不同的颜色，因此上述子像素可以为单色子像素。在具体实施时，在本公开实施例中，如图3与图4a所示，多个重复单元001中的每个可以包括：沿第三方向F3排列的一个第一颜色子像素010、一个第二颜色子像素对020以及一个第三颜色子像素030。其中，第二颜色子像素对020可以包括沿第四方向F4排列的两个第二颜色子像素021、022。其中，第一颜色子像素010被配置为发第一颜色的光，第二颜色子像素021、022被配置为发第二颜色的光，第三颜色子像素被配置为发第三颜色的光。在一些示例中，第一颜色、第二颜色以及第三颜色可以从红色、绿色以及蓝色中进行选取。例如，第一颜色为红色、第二颜色为绿色、第三颜色为蓝色。由此，该重复单元001为红绿蓝子像素的排列结构。当然，本公开实施例包括但不限于此。上述的第一颜色、第二颜色和第三颜色还可为其他颜色。
或者，例如，相邻重复单元组中的重复单元沿第三方向F3是彼此错开的，也就是说，相邻的重复单元组中的相邻的重复单元沿第三方向F3有一定的偏 移量。因此，相邻重复单元组中相同颜色的子像素在第三方向F3上并不是对齐的。在一些示例中，相邻重复单元组中的相同颜色子像素在第三方向F3上的偏移量可以为重复单元在第三方向F3上的尺寸的一半。例如，重复单元在第三方向F3上的尺寸可以为重复单元在第三方向F3上的节距。
在具体实施时，在本公开实施例中，如图3与图4a所示，由于第二颜色子像素对020可以包括沿第四方向F4排列的两个第二颜色子像素021、022，在采用FMM蒸镀工艺制备发光层时，可将每个第二颜色子像素对020中的两个第二颜色子像素021、022的发光层连起来，通过FMM的一个蒸镀孔来形成每个第二颜色子像素对020中的两个第二颜色子像素021、022的发光层。在第二颜色为绿色时，可以在一定程度上降低制备绿色子像素的发光层的工艺难度。
此外，虽然在附图中的各子像素的主体部分的形状包括严格的由两条线段形成的角，但在一些实施例中，各个子像素的有效发光区的形状可以均为圆角图形。也就是说，在上述各种图形形状的基础上，各个子像素的有效发光区的角被倒圆。例如，对于发光层通过掩模版进行蒸镀的情况下，发光层位于角落处的部分则可能会自然形成圆角形状。
在一些示例中，如图3和图4a所示，第一颜色子像素010和第三颜色子像素030的主体部分的形状可以均为六边形，该六边形的三组对边均平行。每个第二颜色子像素021、022的主体部分的形状可以为五边形，该五边形包括非直角交叉的两条边、一组平行的对边以及一条垂直边，垂直边与一组平行的对边垂直，非直角交叉的两条边连接于一组平行的对边之间；其中，每个第二颜色子像素对020中的第二颜色子像素021、022中的垂直边相邻设置。
在一些示例中，如图3和图4a所示，第一颜色子像素010的主体部分中一组较长的平行对边和第三颜色子像素030的主体部分中一组较长的平行对边，分别与第二颜色子像素021、022中的主体部分的一组平行的对边平行。进一步地，示例性地，第一颜色子像素010的有效发光区90-010中一组较长的平行对边和第三颜色子像素030的有效发光区90-030中一组较长的平行对 边，分别与第二颜色子像素021、022的有效发光区90-021、90-022中的一组平行的对边平行。
在一些示例中，如图3和图4a所示，第一颜色子像素010的面积大于一个第二颜色子像素020的面积，第三颜色子像素030的面积大于一个第二颜色子像素020的面积。例如，第一颜色子像素010的有效发光区90-010的面积大于一个第二颜色子像素020的有效发光区90-021、90-022的面积，第三颜色子像素030的有效发光区90-030的面积大于一个第二颜色子像素020的有效发光区90-021、90-022的面积。
在具体实施时，在本公开实施例中，如图3与图4a所示，在第四方向F4上相邻的两个重复单元在第三方向F3上的交错距离大于从第一颜色子像素010的最大跨度、第二颜色子像素021的最大跨度、第二颜色子像素022的最大跨度以及第三颜色子像素030的最大跨度中的一个或其结合。例如，在第二方向F1上相邻的两个重复单元在第三方向F3上的交错距离大于从第一颜色子像素010的有效发光区90-010的最大跨度d010、第二颜色子像素021的有效发光区90-021的最大跨度d020、第二颜色子像素022的有效发光区90-022的最大跨度d020以及第三颜色子像素030的有效发光区90-030的最大跨度d030中的一个或其结合。
在具体实施时，在本公开实施例中，如图3与图4a所示，在一个重复单元001中，第二颜色子像素对020中的第二颜色子像素021与第二颜色子像素022在第四方向F4上的最远距离大于第一颜色子像素010的任意两点在第四方向F4上的最远距离。例如，在一个重复单元001中，第二颜色子像素对020中的第二颜色子像素021的有效发光区90-021与第二颜色子像素022的有效发光区90-022在第四方向F4上的最远距离大于第一颜色子像素010的有效发光区90-010的任意两点在第四方向F4上的最远距离。
在具体实施时，在本公开实施例中，如图3与图4a所示，在一个重复单元001中，第二颜色子像素对020中的第二颜色子像素021与第二颜色子像素022在第四方向F4上的最远距离大于第三颜色子像素030的任意两点在第 四方向F4上的最远距离。例如，在一个重复单元001中，第二颜色子像素对020中的第二颜色子像素021的有效发光区90-021与第二颜色子像素022的有效发光区90-022在第四方向F4上的最远距离大于第三颜色子像素030的有效发光区90-030的任意两点在第四方向F4上的最远距离。
在具体实施时，在本公开实施例中，如图3与图4a所示，第一颜色子像素的相邻子像素不包括第一颜色子像素010，第二颜色子像素对020的相邻子像素不包括第二颜色子像素，第三颜色子像素030的相邻子像素不包括第三颜色子像素030。
在具体实施时，在本公开实施例中，如图3与图4a所示，在第三方向F3和第四方向F4上，两个第一颜色子像素010由除第一颜色子像素之外的其他子像素分割，两个第三颜色子像素030由除第三颜色子像素之外的其他子像素分割，两个第二颜色子像素对由除第二颜色子像素之外的其他子像素分割。
在具体实施时，在本公开实施例中，如图3与图4a所示，以第二方向F1上的两个相邻的重复单元排列为一个重复组。示例性地，同一个重复组中，一个重复单元中的第二颜色子像素对020在另一个重复单元中的一个第一颜色子像素010和一个第三颜色子像素030在第三方向F3上的最大跨度之间。例如，同一个重复组中，一个重复单元中的第二颜色子像素对020的有效发光区在另一个重复单元中的一个第一颜色子像素010的有效发光区和一个第三颜色子像素030的有效发光区在第三方向F3上的最大跨度之间。
在具体实施时，在本公开实施例中，如图3与图4a所示，以第四方向F4上的两个相邻的重复单元排列为一个重复组。示例性地，同一个重复组中，一个重复单元中的第一颜色子像素010在另一个重复单元中的一个第二颜色子像素对020和一个第三颜色子像素030在第三方向F3上的最大跨度之间。例如，同一个重复组中，一个重复单元中的第一颜色子像素010的有效发光区在另一个重复单元中的一个第二颜色子像素对020的有效发光区和一个第三颜色子像素030的有效发光区在第三方向F3上的最大跨度之间。
在具体实施时，在本公开实施例中，如图3与图4a所示，以第三方向F3 上的两个相邻的重复单元排列为一个重复组。示例性地，同一个重复组中，一个重复单元中的第三颜色子像素030在另一个重复单元中的一个第二颜色子像素对020和一个第一颜色子像素010在第三方向F3上的最大跨度之间。例如，同一个重复组中，一个重复单元中的第三颜色子像素030的有效发光区在另一个重复单元中的一个第二颜色子像素对020的有效发光区和一个第一颜色子像素010的有效发光区在第三方向F3上的最大跨度之间。
在具体实施时，在本公开实施例中，如图3与图4a所示，同一个重复单元001中，同一第二颜色子像素对020中的两个第二颜色子像素021、022在第四方向F4上的最小距离小于一个第一颜色子像素010在第四方向F4上的最大跨度。例如，同一个重复单元001中，同一第二颜色子像素对020中的第二颜色子像素021的有效发光区90-021与第二颜色子像素022的有效发光区90-022在第四方向F4上的最小距离小于一个第一颜色子像素010的有效发光区90-010在第四方向F4上的最大跨度d010。
在具体实施时，在本公开实施例中，如图3与图4a所示，同一个重复单元001中，同一第二颜色子像素对020中的两个第二颜色子像素021、022在第四方向F4上的最小距离小于一个第三颜色子像素030在第四方向F4上的最大跨度。例如，同一个重复单元001中，同一第二颜色子像素对020中的第二颜色子像素021的有效发光区90-021与第二颜色子像素022的有效发光区90-022在第四方向F4上的最小距离小于一个第三颜色子像素030的有效发光区90-030在第四方向F4上的最大跨度d030。
在具体实施时，在本公开实施例中，如图3与图4a所示，奇数列重复单元组中重复单元中的子像素排列方式相同，偶数列重复单元组中重复单元中的子像素排列方式相同。例如，除了在基板的显示区的边缘部分之外，每个重复单元中两个绿色子像素的中心连线位于相邻的重复单元组中两个相邻的红色和蓝色子像素的中心之间。此外，上述两个绿色子像素的边缘在上述两个相邻的红色和蓝色子像素的外侧边缘的内侧，这里的外侧边缘是指两个子像素的沿第四方向F4上彼此相对的边缘。也就是说，在第四方向F4上，一 个绿色子像素对在第四方向F4上的延伸的范围不大于上述两个相邻的红色和蓝色子像素在第四方向F4上的延伸的范围。另外，在本公开的实施例中，如果没有特别说明，子像素的“中心”是指子像素(例如：第一颜色子像素、第二颜色子像素或第三颜色子像素)的形状的几何中心。
需要说明的是，在对子像素排列结构进行设计时，子像素一般会设计为规则的形状，比如，六边形、五边形、梯形或其他形状。在进行设计时，子像素的中心可以是上述规则形状的几何中心。然而，在实际制造工艺中，所形成的子像素的形状一般会与上述设计的规则形状有一定的偏差。例如，上述规则的形状的各个角可能会变成圆角，因此，子像素的形状可以为圆角图形。此外，实际制造的子像素的形状还可能会与设计的形状有其他的变化。例如，设计为六边形的子像素的形状在实际制造中可能变成近似椭圆形。因此，子像素的中心也可能并非制作形成的子像素的不规则形状的严格的几何中心。在本公开的实施例中，子像素的中心可以与子像素的形状的几何中心有一定的偏移量。子像素的中心是指从子像素的几何中心出发到子像素的边缘各点的辐射线段上的特定点所围成的区域内的任一点，该辐射线段上的特定点在距离该几何中心1/3该辐射线段的长度处。该子像素中心的定义适用于规则形状的子像素形状的中心，也适用于不规则形状的子像素的中心。
在具体实施时，在本公开实施例中，如图3与图4a所示，在每相邻的三个重复单元组中，该三个相邻列沿着列方向(即第四方向F4)依次包括第一行、第二行和第三行，第二行中第二颜色子像素020对中的两个第二颜色子像素021、022的中心在行方向上的最短距离小于第一行中第一颜色子像素010的中心与第三行中第一颜色子像素010的中心在行方向上的最小距离。
在具体实施时，在本公开实施例中，如图3与图4a所示，第一颜色子像素010在第三方向F3上的边与第三颜色子像素030在第三方向F3上的边平行排列。
在具体实施时，在本公开实施例中，如图3与图4a所示，每个重复单元001中，第一颜色子像素010、第二颜色子像素对020以及第三颜色子像素030 的排列顺序相同。
在具体实施时，在本公开实施例中，如图3与图4a所示，至少一个子像素中，主体部分400在第四方向F4上的尺寸与主体部分400在第三方向F3上的尺寸的比值为γ1，γ1的取值范围为1.2～3。示例性地，蓝色子像素的γ1可以为1.5～1.7，例如，蓝色子像素的γ1可以为1.5、1.6或1.7。示例性地，红色子像素的γ1可以为2.2～2.6。例如，红色子像素的γ1可以为2.2、2.3、2.4、2.5或2.6。当然，在实际应用中，上述子像素的γ1也可以根据实际应用环境进行设计确定，在此不作限定。
在具体实施时，在本公开实施例中，如图3至图5a所示，电致发光显示面板还可以包括：位于第一导电层200与基板100之间的第二绝缘层500以及位于第二绝缘层500与基板100之间的第二导电层600；其中，第二导电层600可以包括：间隔设置的第二电源线610和第二连接线620。其中，第二绝缘层500具有暴露第二连接线620的第二过孔520以及暴露第二电源线610的一部分的第三过孔530。并且，第一电源线210通过第三过孔530与第二电源线610彼此电连接，以实现降低电阻的效果。第一连接线220通过第二过孔520与第二连接线620彼此电连接，第二连接线620与驱动电路中的晶体管的漏极电连接，以实现信号的传输。需要说明的是，上述仅是以第三颜色子像素为例进行说明，其余子像素中的设置以此类推，在此不作赘述。
在具体实施时，在本公开实施例中，如图3、图5a、图6、图7b以及图8b所示，针对相互电连接的第一连接线220和第二连接线620，第一连接线220在基板100的正投影与第二连接线620在基板100的正投影至少部分交叠。可选地，第一连接线220在基板100的正投影与第二连接线620在基板100的正投影重叠。可选地，第一连接线220在基板100的正投影与第二连接线620在基板100的正投影部分交叠。这样可以提高相互电连接的效果。
在具体实施时，在本公开实施例中，如图3与图4b所示，第一电源线210可以包括：沿第一方向F1排列且沿第二方向F2延伸的多个子电源线211，以及电连接各个子电源线211的导通线212；其中，第一方向F1与第二方向F2 不同。示例性地，第一方向F1与第二方向F2垂直。

在具体实施时，在本公开实施例中，如图3与图4a所示，多个重复单元001沿第三方向F3排列形成重复单元组002，重复单元组002沿第四方向F4排列，且相邻两个重复单元组002中的重复单元001错位排列。示例性地，相邻两个重复单元组002中的重复单元001相差1/2个重复单元001的尺寸。需要说明的是，上述的一个重复单元001的尺寸可以为：第三方向F3上相邻两个重复单元001中的相同颜色子像素的中心之间的距离。例如上述的一个重复单元001的尺寸可以为：第三方向F3上相邻两个重复单元001中的第一颜色子像素010的中心之间的距离。
在具体实施时，在本公开实施例中，如图3与图4a所示，第三颜色子像素030中的主体部分413在基板100的正投影与第一连接线220在基板100的正投影不交叠。第三颜色子像素030中的主体部分413在基板100的正投影与第一电源线210在基板100的正投影交叠。并且，第三颜色子像素030中的主体部分413可以具有沿第一方向F1的第一对称轴。示例性地，第三颜色子像素030中的主体部分413的形状大致为六边形或椭圆形，六边形的短对称轴或椭圆形的短轴与第一方向F1大致平行，六边形的长对称轴或椭圆形的长轴与第二方向F2大致平行，则可以将六边形的短对称轴或椭圆形的短轴 作为第一对称轴。在一些实施例中，第三颜色子像素030中，与主体部分413在基板100的正投影交叠的第一电源线210沿第一对称轴大致呈轴对称，并且与主体部分413在基板100的正投影交叠的第一电源线210的中心与主体部分413的中心大致重叠。这样可以使主体部分413具有沿第一对称轴对称的凸起，以使第一对称轴两侧的主体部分413的区域对称设置，从而可以降低主体部分413的不对称性，使主体部分413的中心区域平坦。从而可以改善有效发光区的发光不对称性，甚至消除有效发光区的发光不对称性，从而可改善，甚至消除显示面板的色偏现象。
在具体实施时，在本公开实施例中，如图3与图4b所示，导通线可以包括第一导通线2121。在第三颜色子像素030中，主体部分413在基板100的正投影覆盖至少一条子电源线211与至少两条第一导通线2121在基板100的正投影。进一步地，第三颜色子像素030中，与主体部分413在基板100的正投影交叠的子电源线211沿第一对称轴大致呈轴对称，且与主体部分413在基板100的正投影交叠的子电源线211覆盖主体部分413的中心。并且，第三颜色子像素030中，主体部分413具有沿第二方向F2的第二对称轴，可以将六边形的长对称轴或椭圆形的长轴作为第二对称轴。其中，与主体部分413在基板100的正投影交叠的至少两条第一导通线2121沿第二对称轴大致呈轴对称。这样可以通过子电源线211和第一导通线2121将第一绝缘层整个抬高，在降低主体部分413的不对称性的基础上，进一步使主体部分413大致平坦，从而使发光层大致平坦，改善，甚至消除显示面板的色偏现象。需要说明的是，本公开中的中心可以为相应结构的几何中心。
在具体实施时，在本公开实施例中，如图3至图4b所示，第三颜色子像素030中，与主体部分413在基板100的正投影交叠的子电源线211和第一导通线2121可以采用十字型设置。并且，正投影中的子电源线211和第一导通线2121形成的十字型结构的中心与主体部分413的中心重叠。示例性地，与主体部分413在基板100的正投影交叠的子电源线211和第一导通线2121还可以采用米字型、井字型、Ⅰ字型、Ⅱ字型以及Ⅲ字型中的一种设置。当 然，本公开实施例包括但不限于此，上述的与主体部分413在基板100的正投影交叠的子电源线211和第一导通线2121还可为其他形状。
在具体实施时，在本公开实施例中，如图3至图4b所示，导通线可以包括第二导通线2122。其中，第二颜色子像素020对中的两个第二颜色子像素021、022之间设置一条第二导通线2122。并且，各第二颜色子像素021、022在基板100的正投影与第二导通线2122在基板100的正投影不交叠。示例性地，第二导通线2122沿第一方向F1延伸为直线形。进一步地，第二颜色子像素021、022中的主体部分413的形状大致为五边形，并且该五边形的对称轴与第二方向大致平行。当然，本公开实施例包括但不限于此，上述主体部分413的形状、第二导通线2122的实施方式还可以为其他形状。

一般为了降低膜层厚度，可以在制备阳极之前，在驱动电路上制备数据线(Data line)和电源线(VDD line)，之后制备平坦层，然后再制备阳极。然而，由于源漏金属层制作的信号线厚度较大，而源漏金属层制作的信号线上的平坦层无法使其完全平坦化，从而导致平坦层上的阳极和阳极上的发光层不平整，导致阳极和阳极上的发光层出现不对称凸起，从而导致从该显示面板的法线的左右两侧以与显示面板的法线呈相同的角度观察时会产生色偏现象。因此，本公开实施例又提供了一些电致发光显示面板，如图13与图14所示，可以包括：多个重复单元001，各重复单元001包括多个子像素，各子像素可以包括：位于基板100上方的第一导电层200，位于第一导电层200上方的第一绝缘层300，位于第一绝缘层300上的阳极400。并且，第一绝缘层300包括第一过孔310，阳极400包括相互电连接的主体部分410和辅助部分420。该第一过孔310暴露第一导电层200的一部分，并且辅助部分420通过第一过孔310与第一导电层200电连接。并且，多个重复单元中的至少一个可以包括：第一颜色子像素010、第二颜色子像素以及第三颜色子像素030；其中，第三颜色子像素030的主体部分413的面积大于第二颜色子像素的主体部分的面积和第一颜色子像素010的主体部分400的面积。第三颜色子像素030的主体部分413与第一导电层200交叠的面积大于第二颜色子像素的主体部分与第一导电层200交叠的面积，且第三颜色子像素030的主体部分413与第一导电层200交叠的面积大于第一颜色子像素010的主体部分411与第一导电层200交叠的面积。这样可以使第一导电层200具有镂空图案，与主体部分410在基板100的正投影交叠的镂空图案的部分被配置为使得主体部分410的至少中心区域AA大致平坦。需要说明的是，图13仅示出了各子像素中的主体部分，辅助部分的实施方式可以参见上述实施例，并且上述仅是以第三颜色子像素为了进行说明，其余子像素中的设置以此类推，在此不作赘述。
本公开实施例提供电致发光显示面板，通过使与主体部分在基板的正投 影交叠的第一导电层沿至少一个对称轴大致呈轴对称。这样可以使该主体部分具有对称的凸起，以使该对称轴两侧的主体部分的区域对称设置，从而可以降低主体部分的不对称性。从而可以改善有效发光区的发光不对称性，甚至消除有效发光区的发光不对称性，从而可改善，甚至消除显示面板的色偏现象。
在具体实施时，在本公开实施例中，如图13至图14b所示，第一导电层200包括：第一桥接线、第一连接线710以及沿第一方向间隔排列多个信号线组720；其中，各子像素中，辅助部分420通过第一过孔310与第一连接线710电连接；各信号线组720包括至少两条不同的信号线721、722，信号线721、722沿第二方向F2延伸；第一方向F1与第二方向F2不同。并且，至少一个子像素中，主体部分在基板的正投影与至少一个信号线组720在基板的正投影交叠；并且，与主体部分在基板的正投影交叠的信号线组中的信号线沿第二方向的中心线关于主体部分沿第二方向的对称轴大致呈轴对称。
示例性地，第一连接线可以与驱动电路中的晶体管的漏极电连接，以实现信号的传输。示例性地，第一桥接线被配置为将驱动电路中的部分晶体管的源极、漏极以及栅线中的至少两个电极进行电连接，以实现信号的传输。需要说明的是，图13仅是示意出各颜色子像素中的主体部分与信号线组的实施方式，其余膜层是实施方式可以参见上述实施例，在此不作赘述。
示例性地，各信号线组720可以包括两条信号线721、722。例如，信号线组720可以包括被配置为传输数据信号的数据线721和被配置为传输驱动电压的电源线722。当然，本公开实施例包括但不限于此。上述的信号线组可以包括的信号线的数量还可为其他数量。
一般在显示领域，一个像素通常包括多个可分别显示单色(例如红色、绿色或蓝色)的子像素，通过控制不同颜色的子像素的比例以实现显示不同的颜色，因此上述子像素可以为单色子像素。在具体实施时，在本公开实施例中，如图13所示，多个重复单元001中的每个可以包括：沿第三方向F3排列的一个第一颜色子像素010、一个第二颜色子像素对020以及一个第三颜 色子像素030。其中，第二颜色子像素对020可以包括沿第四方向F4排列的两个第二颜色子像素021、022。其中，第一颜色子像素010被配置为发第一颜色的光，第二颜色子像素021、022被配置为发第二颜色的光，第三颜色子像素被配置为发第三颜色的光。在一些示例中，第一颜色、第二颜色以及第三颜色可以从红色、绿色以及蓝色中进行选取。例如，第一颜色为蓝色、第二颜色为绿色、第三颜色为红色；或者，第一颜色为红色、第二颜色为绿色、第三颜色为蓝色。由此，该重复单元001为红绿蓝子像素的排列结构。当然，本公开实施例包括但不限于此。上述的第一颜色、第二颜色和第三颜色还可为其他颜色。
在具体实施时，在本公开实施例中，如图13所示，第三方向F3与第一方向F1相同，第四方向F4与第二方向F2相同；第三颜色子像素030的主体部分413在第二方向F2上的尺寸大于第三颜色子像素030的主体部分413在第一方向F1上的尺寸；第一颜色子像素010的主体部分411在第二方向F2上的尺寸大于第一颜色子像素010的主体部分411在第一方向F1上的尺寸。示例性地，第一颜色子像素010的主体部分411在第一方向F1上的尺寸大于第三颜色子像素030的主体部分413在第一方向F1上的尺寸。第一颜色子像素010的主体部分411在第二方向F2上的尺寸小于第三颜色子像素030的主体部分413在第二方向F2上的尺寸。并且，示例性地，可以使第一颜色为蓝色、第二颜色为绿色、第三颜色为红色。
一般主体部分设置为规则形状。示例性地，第一颜色子像素010中的主体部分411具有沿第二方向F2的第三对称轴，可以使主体部分411关于第三对称轴呈轴对称。例如，第一颜色子像素010中的主体部分411的形状大致为六边形或椭圆形，六边形的长对称轴或椭圆形的长轴与第二方向F2大致平行，则可以将六边形的长对称轴或椭圆形的长轴作为主体部分411的第三对称轴。
示例性地，同一第二颜色子像素对022中的第二颜色子像素021的主体部分4121和第二颜色子像素022的主体部分4122通过沿第二方向F2的第四 对称轴大致呈轴对称。即同一第二颜色子像素对022中的主体部分4121和主体部分4122关于第四对称轴呈轴对称。第二颜色子像素021、022中的主体部分4121、4122的形状大致为五边形，该五边形的对称轴与第二方向F2大致平行。
示例性地，第三颜色子像素030的主体部分413具有沿第二方向F2的第二对称轴，可以使主体部分413关于第二对称轴呈轴对称。例如，第三颜色子像素030中的主体部分413的形状大致为六边形或椭圆形，六边形的长对称轴或椭圆形的长轴与第二方向F2大致平行，则可以将六边形的长对称轴或椭圆形的长轴作为主体部分413的第二对称轴。
在具体实施时，在本公开实施例中，如图13与图14a所示，第一颜色子像素010中，主体部分411在基板100的正投影与至少一个信号线组720在基板100的正投影交叠。并且第一颜色子像素010中，与主体部分411在基板100的正投影交叠的信号线组200中的信号线沿第二方向F2的中心线关于第三对称轴大致呈轴对称。示例性地，主体部分411在基板100的正投影与一个信号线组720在基板100的正投影交叠。并且第一颜色子像素010中，与主体部分411在基板100的正投影交叠的信号线组200中的信号线721和722关于第一对称轴大致呈轴对称。这样可以使该主体部分411具有两个对称的凸起，以使该第一对称轴两侧的主体部分411的区域对称设置，从而可以降低主体部分411的不对称性。从而可以改善有效发光区90的发光不对称性，甚至消除有效发光区的发光不对称性，从而可改善，甚至消除显示面板的色偏现象。
为了使主体部分411与信号线组交叠设置的效果较好，在具体实施时，在本公开实施例中，如图13所示，可以使一个信号线组中的数据线和电源线之间的距离小于相邻的两个信号线组之间的距离。当然，一个信号线组中的数据线和电源线之间的距离以及相邻的两个信号线组之间的距离可以根据实际应用环境来设计确定，在此不作限定。
在具体实施时，在本公开实施例中，如图13所示，第三颜色子像素030 中，主体部分413在基板100的正投影与最近邻的信号线组200在基板100的正投影的交叠面积小于主体部分413的面积的10％。示例性地，主体部分413在基板100的正投影与最近邻的信号线组200在基板100的正投影的交叠面积小于主体部分413的面积的8％、5％以及2％中的一个。
在具体实施时，在本公开实施例中，如图13所示，第三颜色子像素030中，主体部分413在基板100的正投影与信号线组200在基板100的正投影不交叠。这样可以使主体部分413下方不设置信号线721、722，使主体部分413尽可能平坦。从而可以改善有效发光区的发光不对称性，甚至消除有效发光区的发光不对称性，从而可改善，甚至消除显示面板的色偏现象。
一般绝缘层中会设置过孔，为了避免过孔对主体部分的影响。在具体实施时，在本公开实施例中，如图13与图14b所示，同一子像素中，主体部分410在基板100的正投影与第一过孔310在基板100的正投影不交叠。示例性地，第一颜色子像素010中的主体部分411在基板100的正投影与第一过孔310在基板100的正投影不交叠。第二颜色子像素021、022中的主体部分4121、4122在基板100的正投影与第一过孔310在基板100的正投影不交叠。第三颜色子像素030中的主体部分413在基板100的正投影与第一过孔310在基板100的正投影不交叠。
在具体实施时，在本公开实施例中，如图13所示，针对一个重复单元组，重复单元组中的第三颜色子像素030的第一过孔310、第二颜色子像素020对中的第二个第二颜色子像素022的第一过孔310以及与该重复单元组相邻的第二颜色子像素对020中的第一个第二颜色子像素021的第一过孔310沿第一方向F1排列于同一直线上。示例性地，第一行的重复单元组002中的第三颜色子像素030的第一过孔310、第二个第二颜色子像素022的第一过孔310，以及第二行的重复单元组002中的第一个第二颜色子像素021的第一过孔310，这三个第一过孔310沿第一方向F1排列于同一直线上，以降低制备这三个第一过孔310时使用的掩膜版(Mask)的设计难度。
