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。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
除非另外定义，本发明实施例中使用的“平行”、“垂直”和“相同”等特征均包括严格意义上的“平行”、“垂直”、“相同”等情况，以及“大致平行”、“大致垂直”、“大致相同”等包含一定误差的情况。例如，上述的“大致”可表示所比较的对象的差值为所比较的对象的平均值的10％，或者5％之内。在本发明实施例的下文中没有特别指出一个部件或元件的数量时，意味着该部件或元件可以是一个也可以是多个，或可理解为至少一个。“至少一个”指一个或多个，“多个”指至少两个。本发明实施例中的“同层设置”指同一材料在经过同一步骤(例如，一步图案化工艺)后形成的多个膜层之间的关系。这里的“同层”并不总是指多个膜层的厚度相同或者多个膜层在截面图中的高度相同。
目前，大多数汽车厂商为了节省生产成本，汽车上包括的仪表和中控设备等具有显示功能的器件大多采用液晶显示产品。由于有机发光二极管(Organic Light Emitting Diode，OLED)显示器件具有低能耗、生产成本低、自发光、宽视角和响应速度快等优点，很多汽车厂商对OLED产品产生了浓厚
的兴趣，将OLED显示产品用在汽车仪表、中控设备、副驾驶显示屏上均有很好的市场前景。
相对于传统的液晶显示器件(LCD)和液晶显示器件升降部件(LCF)的组合结构而言，将以OLED显示器件为基础的车载产品用于替代液晶显示器的设计可以解决摩尔纹以及显示图像时显示亮度不足的问题，但是将OLED作为车载显示器件仍存在以下需要改善的问题：考虑到车载产品的特殊性，像素结构采用了真实的RGB三元像素设计，该像素设计会在很大程度上影响暗态显示效果，所以亟需一种像素排布结构设计能够解决车载产品中OLED器件的上述问题。此外，随着显示技术的快速发展，消费者对显示屏的分辨率的要求越来越高，目前具有高分辨率的像素排列方式为子像素借色方式(SPR，Sub Pixel Rendering)，例如，相邻的像素单元会共用红色子像素R和蓝色子像素B中的至少之一。
本公开的发明人注意到，可以设计一种像素排布结构，使得该像素排布结构的一个像素组中的第二显示单元包括的两个第二子像素和两个第三子像素分别和与之相邻的四个像素组共用，通过借用相邻的像素组中的第二子像素和第三子像素可以减少中心色分离亮斑对人眼的影响，且将具有该像素排布结构的显示面板用于车载系统时，在暗态显示过程中不会造成环境光对驾驶人员视线的影响，从而使得驾驶时的安全性提高。
本公开至少一实施例提供一种像素排布结构，该像素排布结构包括：阵列排布的多个像素组，每个像素组包括第一显示单元和第二显示单元，第一显示单元和第二显示单元均包括发射不同颜色光线的第一子像素、第二子像素和第三子像素；第一显示单元包括一个第一子像素、一个第二子像素和一个第三子像素，第二显示单元包括一个第一子像素和设置在该一个第一子像素的四周的两个第二子像素和两个第三子像素，且第一显示单元和第二显示单元共用一个第一子像素，第一显示单元中的一个第二子像素为第二显示单元中的两个第二子像素中的一个，第一显示单元中的一个第三子像素为第二显示单元中的两个第三子像素中的一个；在一个像素组中的第二显示单元包括的两个第二子像素和两个第三子像素分别和与之相邻的四个像素组共用。该像素排布结构使得一个像素组总共包括5个子像素，每个像素组包括第一显示单元和第二显示单元，该第一显示单元包括的三种颜色的三个子像素和第二显示单元包括的5个子像素中的三个共用，从而减少了子像素的个数，
而且可以在不同的驱动电路的驱动下进行第一图像显示或者第二图像显示。从而，在一个像素组中子像素之间通过借色原理由低分辨率的物理分辨率达到高分辨率的显示效果，从而解决了像素分辨率受限的技术问题。并且，在一个像素组中的第二显示单元包括的两个第二子像素和两个第三子像素分别和与之相邻的四个像素组共用，从而进一步减少了子像素的个数，使得每个像素组的结构变得简单，从而简化了整个显示面板的结构设计。
例如，将该像素排布结构用于车载领域的显示产品的显示区域中时，通过借用子像素可以减少中心色分离亮斑对人眼的影响，在暗态显示过程中不会造成环境光对驾驶人视线产生影响。
例如，图1为本公开至少一实施例提供的一种像素排布结构的平面结构示意图，如图1所示，该像素排布结构100包括：阵列排布的多个像素组101，每个像素组101包括第一显示单元102和第二显示单元103。即每个像素组101为一个重复单元，多个重复单元在相互交叉的第一方向X和第二方向Y上阵列排布，如图1所示，该第一方向X和第二方向Y相交，但并不相互垂直，第一方向X和第二方向Y之间的夹角为钝角。
例如，图2为本公开至少一实施例提供的一种第一显示单元的平面结构示意图，图3为本公开至少一实施例提供的一种第二显示单元的平面结构示意图，如图2和图3所示，该第一显示单元102和第二显示单元103均包括发射不同颜色光线的第一子像素104、第二子像素105和第三子像素106，只是在第一显示单元102和第二显示单元103中子像素的个数和排布方式不同。第一显示单元102包括一个第一子像素104、一个第二子像素105和一个第三子像素106，第二显示单元103包括一个第一子像素104和设置在该一个第一子像素104的四周的两个第二子像素105和两个第三子像素106，且第一显示单元102和第二显示单元103共用一个第一子像素104，第一显示单元102中的一个第二子像素105为第二显示单元103中的两个第二子像素105中的一个，第一显示单元102中的一个第三子像素106为第二显示单元103中的两个第三子像素106中的一个，即每个像素组101包括5个子像素，第二显示单元103包括一个像素组101中的5个子像素，与该第二显示单元103位于同一个像素组101中的第一显示单元102包括一个像素组101中的3个子像素，而且，在一个像素组101中的第二显示单元103包括的两个第二子像素105和两个第三子像素106分别和与之相邻的四个像素组101
共用。
例如，在一个示例中，该第一子像素104、第二子像素105和第三子像素106可以分别为蓝色子像素B、绿色子像素G和红色子像素R，即该第一显示单元102包括一个蓝色子像素B、一个绿色子像素G和一个红色子像素R，该第二显示单元103包括一个蓝色子像素B和设置在该一个蓝色子像素B的四周的两个绿色子像素G和两个红色子像素R。当然，本公开的实施例不限于此，还可以是第一子像素104、第二子像素105和第三子像素106分别为绿色子像素G、蓝色子像素B和红色子像素R，即该第一显示单元102包括一个绿色子像素G、一个蓝色子像素B和一个红色子像素R，该第二显示单元103包括一个绿色子像素G和设置在该一个绿色子像素G的四周的两个蓝色子像素B和两个红色子像素R；还可以是，第一子像素104、第二子像素105和第三子像素106分别为红色子像素R、绿色子像素G和蓝色子像素B，即该第一显示单元102包括一个红色子像素R、一个绿色子像素G、和一个蓝色子像素B，该第二显示单元103包括一个红色子像素R和设置在该一个红色子像素R的四周的两个蓝色子像素B和两个绿色子像素G。
例如，如图2和图3所示，每个第一子像素104的面积大于每个第二子像素105的面积，且大于每个第三子像素106的面积，由于蓝色子像素B的发光亮度最低，为了保证最终形成的显示面板显示的白光的均匀性，通常需要把面积最大的第一子像素104限定成蓝色子像素B，面积较小的第二子像素105和第三子像素106中的一个为红色子像素R，另一个为绿色子像素G。
例如，如图2所示，是在由水平方向和垂直于水平面的方向形成的平面中示出的第一显示单元102，该第三子像素106位于水平面上，该第一子像素104所在的平面垂直于水平面，该第二子像素105所在的平面垂直于水平面。该第一显示单元102包括的第一子像素104、第二子像素105和第三子像素106为长方体的一半的结构。第一子像素104所在的平面、第二子像素105所在的平面和第三子像素106所在的平面相较交于一个点，第一子像素104所在的平面和第二子像素105所在的平面共用一个边，第二子像素105所在的平面和第三子像素106所在的平面共用一个边，第一子像素104所在的平面和第三子像素106所在的平面也共用一个边，但本公开的实施例不限于此。
需要说明的是，尽管在图1、图2和图3中，第一子像素104、第二子
像素105和第三子像素106的四周均设置了一个方框，但是实际上这些方框都是虚拟的方框，是为了更加清楚地展示各个子像素之间的关系。例如，第一子像素104所在的平面和第二子像素105所在的平面共用的一个边为包围第一子像素104的方框和包围第二子像素105的方框共用的一个边。第二子像素105所在的平面和第三子像素106所在的平面共用的一个边为包围第二子像素105的方框和包围第三子像素106的方框共用的一个边。第一子像素104所在的平面和第三子像素106所在的平面共用的一个边为包围第一子像素104的方框和包围第三子像素106的方框共用的一个边。
例如，在像素驱动电路驱动第一显示单元102进行显示时，一个第一子像素104、一个第二子像素105和一个第三子像素106构成一个像素点，进行常规的R、G、B三原色显示。
例如，第二显示单元103采用Pentile显示，Pentile显示是一种通过相邻像素点共用子像素的方式，减少子像素的个数，从而达到以低分辨率去模拟高分辨率的效果，进而可以实现在同样亮度下观看者的视觉感受亮度更高的效果，此外，该种像素排布结构还使得制造显示面板的成本更低。在像素驱动电路驱动第二显示单元103进行显示时，Pentile显示的一个像素点会“借”用与其相邻的像素点的另一种颜色来构成三基色。Pentile排列伴随着OLED显示材质的诞生而出现，对于主动发光的OLED显示器件来说，OLED的RGB对应的分别是发射红色光线的有机材料、发射绿色光线的有机材料和发射蓝色光线的有机材料。目前的显示器对分辨率的要求较高，这就要求每种发光材料制作的很小且高密度的集成，这在工艺上的难度较大，制作成本也很高。采用Pentile排列，相邻的显示单元采用子像素借用的方式，可以使得每个子像素的发光层的面积较大，从而可以降低制备过程中的工艺难度，且生产成本也会降低。而且，Pentile显示的像素密度更高，因此，能更好地展现高分辨率影像和绚丽多彩的图像，而且还能在直接阳光的照射下清晰地显示画面。
例如，图4为本公开至少一实施例提供的再一种第一显示单元的平面结构示意图，如图4所示，是在由水平方向和垂直于水平面的方向形成的平面中示出的第一显示单元102，该第三子像素106位于水平面上，该第一子像素104所在的平面垂直于水平面，该第二子像素105所在的平面垂直于水平面。第一子像素104所在的平面、第二子像素105所在的平面和第三子像素
106所在的平面相较交于一个点，第一子像素104所在的平面和第二子像素105所在的平面共用一个边，第一子像素104所在的平面和第三子像素106所在的平面也共用一个边，但是，第二子像素105所在的平面和第三子像素106所在的平面没有共用的边，但本公开的实施例不限于此。
例如，图5示出了图2中的第一显示单元包括的第一子像素、第二子像素和第三子像素的几何中心的连接结构，如图5所示，该第一显示单元102包括的一个第一子像素104的几何中心A、一个第二子像素105的几何中心B和一个第三子像素106的几何中心C连接形成的三角形ABC为锐角三角形。例如，该锐角三角形中的<ABC、<ACB和<BAC均为锐角，即均小于90o。该种设置可以使得第一显示单元102的结构更加紧凑，使得最终形成的第一显示单元102进行显示时的显示画面更加均匀。
例如，如图5所示，在一个第一显示单元102中，第一子像素104和第二子像素105之间具有第一间距L1，第二子像素105和第三子像素106之间具有第二间距L2，第一子像素104和第三子像素106之间具有第三间距L3，第一间距L1、第二间距L2和第三间距L3均相等，这样可以使得第一子像素104、第二子像素105和第三子像素106中的任意两个之间的距离相等，可以进一步确保在第一显示单元102进行显示时显示画面的均匀性。
例如，图6示出了图3中的第二显示单元包括的一个第一子像素、两个第二子像素和两个第三子像素的几何中心的连接结构，如图6所示，该第二显示单元103包括的两个第二子像素105的几何中心M、N和两个第三子像素106的几何中心P、Q连接形成的四边形为平行四边形MNPQ，且第二显示单元103包括的一个第一子像素104的几何中心K和平行四边形MNPQ的两条对角线MN和PQ的交点重合，该种结构设计使得第二子像素105包括的一个第一子像素、两个第二子像素和两个第三子像素的结构更加紧凑，从而使得最终形成的第二显示单元103进行显示时的显示画面更加均匀，且可以使得该像素排布结构中可以采用尽量少数量的子像素来实现两种不同的显示方式。
例如，如图6所示，在第二显示单元103中，第一子像素104和任一第二子像素105之间具有第四间距L4，第二子像素105和与之相邻的第三子像素106之间具有第五间距L5，第一子像素104和任一第三子像素106之间具有第六间距L6，该第四间距L4、第五间距L5和第六间距L6均相等，该种
设计可以使得第二显示单元103在进行图像显示时显示的画面更加均匀。
例如，在一个示例中，在一个像素组101中，该第二显示单元103包括的两个第二子像素105的面积相等且形状相同，且该两个第二子像素105在第一子像素104的两侧相对设置，例如，该两个第二子像素105中的一个在第一子像素104的左侧，另一个在第一子像素104的右侧，位于第一子像素104的左侧的第二子像素105与第一子像素104之间的最小距离等于位于第一子像素104的右侧的第二子像素105与第一子像素104之间的最小距离。两个第三子像素106的面积相等且形状相同，且该两个第三子像素106在第一子像素104的两侧相对设置，例如，该两个第三子像素106中的一个在第一子像素104的上侧，另一个在第一子像素104的下侧，位于第一子像素104的上侧的第三子像素106与第一子像素104之间的最小距离等于位于第一子像素104的下侧的第三子像素106与第一子像素104之间的最小距离。
例如，在图6所示的结构中，第一子像素104为蓝色子像素B，第二子像素105为红色子像素R和绿色子像素B中的一种，第三子像素106为红色子像素R和绿色子像素G中的另一种，例如，第一子像素104为蓝色子像素B，第二子像素105为红色子像素R，第三子像素106为绿色子像素G。图6所示的像素组中位于第一子像素104左侧的第二子像素105和位于该像素组左侧的相邻像素组共用，图6所示的像素组中位于第一子像素104右侧的第二子像素105和位于该像素组右侧的相邻像素组共用。图6所示的像素组中位于第一子像素104上侧的第三子像素106和位于该像素组上侧的相邻像素组共用，图6所示的像素组中位于第一子像素104下侧的第三子像素105和位于该像素组下侧的相邻像素组共用。
例如，结合图1和图6，多个像素组101在第一方向X和第二方向Y上阵列排布，第一方向X和第二方向Y相交且不垂直，多个第二显示单元103的几何中心K在第一方向X和第二方向Y上阵列排布。
例如，在图6所示的结构中，第一子像素104的平面形状为矩形，两个第二子像素105和两个第三子像素106的平面形状均为平行四边形，该第一子像素104的面积大于任意一个第二子像素105的面积，且该第一子像素104的面积大于任意一个第三子像素106的面积，形成该第二显示单元的5个子像素的排布结构的形状为异形六边形。
例如，图7为本公开至少一实施例提供的再一种第二显示单元的平面结
构示意图，如图7所示，该第一子像素104的平面形状、第二子像素105的平面形状和第三子像素106的平面形状均为矩形，该第二显示单元103包括的两个第二子像素105的面积相等且形状相同，且在第一子像素104的两侧相对设置，例如，该两个第二子像素105中的一个在第一子像素104的左侧，另一个在第一子像素104的右侧，位于左侧的第二子像素105与第一子像素104之间的最小距离等于位于右侧的第二子像素105与第一子像素104之间的最小距离。两个第三子像素106的面积相等且形状相同，且在第一子像素104的两侧像是对设置，例如，该两个第三子像素106中的一个在第一子像素104的上侧，另一个在第一子像素104的下侧，位于上侧的第三子像素106与第一子像素104之间的最小距离等于位于下侧的第三子像素106与第一子像素104之间的最小距离。第一子像素104的长边的长度大于第三子像素106的长边的长度，且第三子像素106的长边的长度大于第二子像素105的长边的长度。第一子像素104的短边的长度大于第二子像素105的短边的长度，且第二子像素105的短边的长度大于第三子像素106的短边的长度。从图7中可以看出，第一子像素104的面积大于每个第三子像素106的面积，每个第三子像素106的面积大于每个第二子像素105的面积。且在图7中，第一子像素104和任一第二子像素105之间具有第四间距L4，第二子像素105和与之相邻的第三子像素106之间具有第五间距L5，第一子像素104和任一第三子像素106之间具有第六间距L6，该第四间距L4、第五间距L5和第六间距L6均相等，该种设计可以使得第二显示单元103在进行显示时显示的画面更加均匀。
例如，图8为本公开至少一实施例提供的又一种第二显示单元的平面结构示意图，如图8所示，该第一子像素104的平面形状为菱形，第二子像素105的平面形状和第三子像素106的平面形状均为平行四边形，且第一子像素104的相对边的最大距离大于第二子像素105的相对边的最大距离，第二子像素105的相对边的最大距离大于第三子像素106的相对边的最大距离。从图8中也可以看出，第一子像素104的面积大于每个第三子像素106的面积，每个第三子像素106的面积大于每个第二子像素105的面积。且在图8中，第一子像素104和任一第二子像素105之间具有第四间距L4，第二子像素105和与之相邻的第三子像素106之间具有第五间距L5，第一子像素104和任一第三子像素106之间具有第六间距L6，该第四间距L4、第五间距L5
和第六间距L6均相等，该种设计可以使得第二显示单元103在进行显示时显示的画面更加均匀。
例如，在本公开至少一实施例提供的像素排布结构中，该第一子像素104、第二子像素105和第三子像素106的平面形状可以均包括圆弧形部分，该圆弧形部分使得像素开口的边缘更加平滑，从而可以减弱显示画面的锯齿感。
例如，图9为本公开至少一实施例提供的又一种第二显示单元的平面结构示意图，如图9所示，一个第一子像素104、两个第二子像素105和两个第三子像素106的平面形状均为椭圆形，且第一子像素104对应的椭圆形的短径大于第二子像素105对应的椭圆形的短径以及第三子像素106对应的椭圆形的短径，且第二子像素105对应的椭圆形的短径大于或者等于第三子像素106对应的椭圆形的短径；第一子像素104对应的椭圆形的长径大于或者等于第三子像素106对应的椭圆形的长径，第三子像素106对应的椭圆形的长径大于第二子像素105对应的椭圆形的长径。将该一个第一子像素104、两个第二子像素105和两个第三子像素106的平面形状均设置成椭圆形可以使得每个像素开口的边缘更加平滑，从而可以减弱显示画面的锯齿感。从图9中也可以看出，第一子像素104的面积大于每个第三子像素106的面积，每个第三子像素106的面积大于每个第二子像素105的面积。且在图9中，第一子像素104和任一第二子像素105之间具有第四间距L4，第二子像素105和与之相邻的第三子像素106之间具有第五间距L5，第一子像素104和任一第三子像素106之间具有第六间距L6，该第四间距L4、第五间距L5和第六间距L6均相等，该种设计可以使得第二显示单元103在进行显示时显示的画面更加均匀。
例如，图10为本公开至少一实施例提供的又一种第二显示单元的平面结构示意图，如图10所示，一个第一子像素104、两个第二子像素105和两个第三子像素106的平面形状均为圆形，且第一子像素104对应的圆形的直径大于第二子像素105对应的圆形的直径，第二子像素105对应的圆形的直径大于第三子像素106对应的圆形的直径，即第一子像素104的面积大于第二子像素105的面积，第二子像素105的面积大于第三子像素106的面积。如图10所示，第一子像素104和任一第二子像素105之间具有第四间距L4，第二子像素105和与之相邻的第三子像素106之间具有第五间距L5。该第四
间距L4、第五间距L5和第六间距L6中的任意两个不相等。
例如，在图10所示的实施例中，第一子像素104和任一第三子像素106之间具有第六间距L6，该第五间距L5大于第四间距L4，第四间距L4大于第六间距L6。
当然，本公开的实施例不限于此，在图10所示的结构中，该第四间距L4、第五间距L5和第六间距L6中的任意两个也可以相等。
需要说明的是，在本公开的实施例中，该第一子像素104、第二子像素105和第三子像素106的平面形状均包括圆弧形部分的实施例不限于上述图9和图10所示的实施例，只要能够满足第一子像素104、第二子像素105和第三子像素106的平面形状均包括圆弧形部分即可，例如，可以是第一子像素104、第二子像素105和第三子像素106的平面形状均包括扇形部分、弓形部分或者半圆形部分等。
例如，在图6至图10所示的实施例中，第二显示单元103包括的两个第二子像素105的几何中心M和N，和两个第三子像素106的几何中心P和Q连接形成的四边形为平行四边形MNPQ，且第二显示单元103包括的一个第一子像素104的几何中心K和平行四边形MNPQ的两条对角线MN和PQ的交点重合。
例如，在图6至图10所示的实施例中，第二显示单元103包括的一个第一子像素104、两个第二子像素105和两个第三子像素106位于异形六边形中，例如，图11为本公开至少一实施例中异形六边形的结构示意图，该异形六边形如图11所示，在该异形六边形中相邻的两条边均相互垂直。例如，将每个像素组的外轮廓设为异形六边形可以使得像素组整体的结构均匀，同时基于红绿蓝三原色能够更加均匀分配，使得显示效果稳定。

时，分别通过第一显示单元和第二显示单元进行显示。
