详细描述
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中的附图，对本公开实施例中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一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动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。
本公开提供了一种显示基板，参照图1示意性地示出了本公开提供的一种显示基板的平面结构示意图。如图1所示，该显示基板的透明显示区域包括彼此隔开的多个岛区21，以及位于相邻岛区21之间的孔区22。岛区21用于显示图像，孔区22用于透过环境光线。
参照图2和图3示意性地示出了本公开提供的两种显示基板的像素结构示意图。如图2和图3所示，岛区21可以包括多个子像素，多个子像素包括第一子像素31、第二子像素32和第三子像素33。
其中，第一子像素31位于虚拟四边形A的四个顶点位置处；第二子像素32和第三子像素33位于虚拟四边形A的两条中线位置处，以将相邻的第一子像素31分隔开。
虚拟四边形A中的每个顶点对应设置一个第一子像素31。虚拟四边形A的顶点可以位于该位置处的第一子像素31范围内的任一位置，不仅局限于虚拟四边形A的顶点为该第一子像素31的中心。
第二子像素32和第三子像素33位于虚拟四边形A的中线位置处，是指中线经过第二子像素32和第三子像素33范围内的任一位置，或者第二子像素32和第三子像素33的至少一个排布方向大致沿中线的延伸方向。
其中，中线为虚拟四边形A中一对相对设置的侧边中点之间的连线。如图2和图3所示，虚拟四边形A的两条中线包括第一中线a1和第二中线a2。
本公开中，通过设置第一子像素31位于虚拟四边形A的顶点位置，将第二子像素32和第三子像素33设置在虚拟四边形A的第一中线a1和第二中线a2位置处，从而实现将任意两个第一子像素31分隔开。也就是，任意两个第一子像素31被第二子像素32和/或第三子像素33分隔开，这样可以确保在虚 拟四边形A中，任意两个第一子像素31互不相邻，避免第一子像素31集中设置，从而提高第一子像素31的分散度。
在具体实现中，对于每一个第一子像素31，该第一子像素31与周围的一个第二子像素32和一个第三子像素33构成一个白色像素W。这样，可以在一个虚拟四边形A内形成四个白色像素W(分别示出在图5中的a图、b图、c图和d图中)。其中，图5示出的是同一虚拟四边形内的多个子像素所构成的白色像素示意图，该虚拟四边形的像素结构如图2所示。
在显示的过程中，每个白色像素W的亮度中心形成一个白色亮度中心C(如图5所示)。
本公开提供的显示基板，由于第一子像素31之间的间隔较大，在虚拟四边形A中的分布较为分散，因此可以将第一子像素31设置为人眼感知较为强烈或人眼敏感度较高的颜色子像素(如绿色子像素等)，由于第一子像素31的分散度较高，因此第一子像素31与岛区21内的第二子像素32和第三子像素33混色形成的白色亮度中心C的分散度也相应提高，提高了白色亮度中心C在岛区21内的分布均匀性，避免白色亮度中心C在岛区21内局部聚集，相当于增大岛区21内白色亮度中心C的数量，从而可以提升显示画面的精细度。
另外，由于岛区21内白色亮度中心C的分布更加均匀，在岛区21的边缘也分布有白色亮度中心C，因此可以缩小分别位于相邻岛区21上的两个白色亮度中心C的间距(如图6)，从而可以缩小相邻岛区21之间的暗区间隔，减少显示画面颗粒感。
其中，图6示出的是相邻的几个岛区中白色亮度中心的分布示意图，各岛区的像素结构如图2所示。
如图5所示，在虚拟四边形A内，每个第一子像素31可以独立驱动，每个第一子像素31对应一个白色像素W。
虚拟四边形A中的各白色像素W可以独立地包括一个第一子像素31。
虚拟四边形A中相邻的两个白色像素W之间可以共用第二子像素32和/或第三子像素33。
具体地，相邻的两个第一子像素31对应的两个白色像素W，可以共用位于这相邻的两个第一子像素31之间的第二子像素32或第三子像素33。
例如，在虚拟四边形A中，右下角的白色像素W(如图5中的a图所示)与左下角的白色像素W(如图5中的b图所示)共用位于右下角的第一子像素31与左下角的第一子像素31之间的第二子像素32。
在虚拟四边形A中，右上角的白色像素W(如图5中的c图所示)与左上角的白色像素W(如图5中的d图所示)共用位于右上角的第一子像素31与左上角的第一子像素31之间的第二子像素32。
在虚拟四边形A中，右下角的白色像素W(如图5中的a图所示)与右上角的白色像素W(如图5中的c图所示)共用位于右下角的第一子像素31与右上角的第一子像素31之间的第三子像素33。
在虚拟四边形A中，左下角的白色像素W(如图5中的b图所示)与左上角的白色像素W(如图5中的d图所示)共用位于左下角的第一子像素31与左上角的第一子像素31之间的第三子像素33。
为了驱动透明显示区域内的子像素进行发光显示，可以采用以下两种方案：即内置驱动电路和外置驱动电路。其中，外置驱动电路具体是指将子像素的发光器件设置在透明显示区域内，将驱动该发光器件发光的驱动电路设置在透明显示区域外。内置驱动电路具体是指将发光器件以及驱动该发光器件发光的驱动电路都设置在透明显示区域内部。
可选地，本公开提供的显示基板可以采用内置驱动电路的方案，从而简化结构设计，降低成本。
相关技术中，当在透明显示区域采用内置驱动电路时，通常通过降低透明显示区域的像素密度来提高环境光线的透过率。然而，降低像素密度导致单色子像素之间的距离增大，进而导致单色子像素之间的光线混合存在一定困难。
本公开中，通过将透明显示区域设计成岛状结构，即透明显示区域包括多个相互间隔设置的岛区21以及位于岛区21周边的孔区22。这样，一方面可以不必降低岛区21内的像素密度，降低岛区21内的多个子像素之间的距离，使得不同颜色子像素之间能够自由地混合出不同颜色，改善显示效果；另一方面，由于孔区22能够透过环境光线，从而可以提高透明显示区域的环境光线透过率，提高透明显示区域的透明度和清晰度，改善屏下摄像头的拍照效果。
需要说明的是，本公开提供的显示基板也可以在透明显示区域采用外置驱动电路的方案，这样可以进一步提高透明显示区域的环境光线透过率，同时不必降低透明显示区域的像素密度，提高透明显示区域的显示效果。当采用外置驱动电路的方案时，可以采用透明走线连接子像素的发光器件和外置的驱动电路，从而降低走线对透明显示区域透过率的影响。
在具体实现中，第二子像素32和第三子像素33位于虚拟四边形A的两条中线位置处的实现方式有多种。
在一种可选的实现方式中，至少一个第二子像素32和至少一个第三子像素33沿第一中线a1依次排布，至少一个第二子像素32和至少一个第三子像素33沿第二中线a2依次排布。如图3所示，一个第二子像素32和一个第三子像素33依次排布在第一中线a1上，一个第二子像素32和一个第三子像素33依次排布在第二中线a2上。
在图3所示的结构中，由于两个第三子像素33相邻且集中设置虚拟四边形A的左上角，两个第二子像素32相邻且集中设置虚拟四边形A的右下角，这种结构很容易出现边缘色偏不良。
在另一种可选的实现方式中，如图2所示，在虚拟四边形A设置有至少一个第二子像素32和多个第三子像素33，至少一个第二子像素32沿第一中线a1依次排布，多个第三子像素33位于第二中线a2上且对称设置在第二子像素32的两侧。
由于第二子像素32沿第一中线a1依次排布，第三子像素33设置在第二中线a2上且对称分布在第二子像素32的两侧，即第二子像素32靠近虚拟四边形A的中间设置，第三子像素33靠近虚拟四边形A的边缘设置，因此可以避免同时将第二子像素32和第三子像素33靠近虚拟四边形A的边缘设置可能产生的边缘色偏问题。
由于第三子像素33设置在第二子像素32的两侧，因此第三子像素33的分散度较高，可以避免集中设置第三子像素33而导致的色偏问题。这种情况下，可以将第三子像素33设置为人眼敏感度相对第二子像素32较高的颜色子像素(如红色子像素)，这样可以进一步避免发生边缘彩边的问题，减少色偏不良。
由于第二子像素32设置在虚拟四边形A的中间位置，第二子像素32的 设置较为集中，因此可以将第二子像素32设置为人眼敏感度相对较低的颜色子像素(如蓝色子像素)，从而可以改善混色效果。
可选地，在虚拟四边形A中，多个第三子像素33互不相邻。
通过设置多个第三子像素33互不相邻，如图2所示，即任意两个第三子像素33被第二子像素32分隔开，这样可以进一步提高第三子像素33的分散度，进一步改善边缘色偏不良。
可选地，如图2所示，第二子像素32至少具有第一长边b1和第一短边c1，第一长边b1与第一中线a1平行，第一短边c1与第二中线a2平行。
当第二子像素32的形状为矩形时，第一长边b1即矩形的长边，第一短边c1即矩形的短边，如图2所示出的。当第二子像素32的形状为平行四边形时，第一长边b1即平行四边形的长边，第一短边c1即平行四边形的短边。当第二子像素32的形状为椭圆形、腰圆形或跑道形时，如图9所示，第一长边b1即椭圆形、腰圆形或跑道形的最小外接矩形的长边，第一短边c1即椭圆形、腰圆形或跑道形的最小外接矩形的短边。
第三子像素33至少具有第二长边b2和第二短边c2，第二长边b2与第一中线a1平行，第二短边c2与第二中线a2平行。
当第三子像素33的形状为矩形时，第二长边b2即矩形的长边，第二短边c2即矩形的短边，如图2所示出的。当第三子像素33的形状为平行四边形时，第二长边b2即平行四边形的长边，第二短边c2即平行四边形的短边。当第三子像素33的形状为椭圆形、腰圆形或跑道形时，如图9所示，第二长边b2即椭圆形、腰圆形或跑道形的最小外接矩形的长边，第二短边c2即椭圆形、腰圆形或跑道形的最小外接矩形的短边。
可选地，第二子像素32的形状为矩形，本公开对此不作限定。

可选地，第一子像素31的形状为正方形。该正方形中一对相对设置的侧边可以与第一中线a1平行，另一对相对设置的侧边可以与第二中线a2平行。
其中，矩形可以为倒角矩形或非倒角矩形。正方形可以为倒角正方形或非倒角正方形，本公开对此不作限定。
可选地，在虚拟四边形A中设置有两个第二子像素32和两个第三子像素33，本公开对此不作限定。
可选地，如图2和图3所示，相邻设置的第一子像素31与第二子像素32中，第一子像素31靠近第二子像素32的侧边与第二子像素32靠近第一子像素31的侧边可以相互平行。

在图2所示的像素结构中，由于第一子像素31的分散度最大，第二子像素32的分散度最小，并且人眼对绿色子像素的敏感度最大，人眼对蓝色子像素的敏感度最小，因此，当设置第一子像素31为绿色子像素，第二子像素32为蓝色子像素，第三子像素33为红色子像素时，可以进一步提升显示效果，改善边缘色偏问题。
可选地，红色子像素的面积大于或等于绿色子像素的面积，且小于或等于蓝色子像素的面积。
由于蓝色发光器件的寿命衰减较快、发光效率较低，通过设置较大面积的蓝色子像素，可以提高蓝色子像素的发光效率，延长显示基板的使用寿命。
示例性地，红色子像素的面积、绿色子像素的面积以及蓝色子像素的面 积之间的比值可以为2:1.5:5，本公开对此不作限定。

如图2至图4以及图7所示，岛区21的形状为四边形，靠近四边形顶点设置的子像素中、靠近四边形顶点的顶角为倒角。
可选地，四边形的顶角为倒角。
其中，倒角可以为圆倒角或直倒角。
通过将岛区21的四个顶角以及对应位置处子像素的顶角设置为倒角，可以降低直角发光区对孔区透过的环境光线产生干涉影响。
在图2、图3和图7中，岛区21包括一个虚拟四边形A，靠近岛区21的四边形顶点设置的子像素即位于虚拟四边形A顶点位置处的四个第一子像素31，这四个第一子像素31中的每一个第一子像素31中、靠近岛区21四边形顶点的一个顶角为倒角。该倒角可以为直倒角，如图2和图3所示出的；还可以为圆倒角，如图7所示出的。
在图4中，岛区21包括四个虚拟四边形A，靠近四边形顶点设置的子像素为四个第一子像素31，这四个第一子像素31中的每一个第一子像素31中、靠近岛区21四边形顶点的一个顶角为倒角。在图4中，该倒角为直倒角。

在具体实现中，子像素内设置有发光器件和驱动电路。驱动电路分别与发光器件和信号线24电连接，用于根据信号线24提供的信号，驱动发光器件发光。
可选地，信号线24设置在桥区23范围内。
其中，子像素中设置有驱动电路，即该子像素采用内置驱动电路的结构。
在具体实现中，不同颜色的子像素中设置可以不同颜色的发光器件，例如，红色子像素中设置有红色发光器件，绿色子像素中设置有绿色发光器件， 蓝色子像素中设置有蓝色发光器件。
可选地，驱动电路和发光器件可以层叠设置在子像素中，驱动电路背离发光器件的出光侧设置。驱动电路可以包括薄膜晶体管和电容等。发光器件主要包括层叠设置的阳极、有机发光层和阴极。
驱动电路可以与发光器件的阳极连接，用于向阳极提供驱动发光器件发光的电流。
当多个岛区21沿第一方向和第二方向排布时，如图1所示，桥区23可以包括第一桥区231和第二桥区232，第一桥区231连接第一方向上相邻的两个岛区21，第二桥区232连接第二方向上相邻的两个岛区21。
在具体实现中，如图1所示，信号线24可以包括第一信号线241和第二信号线242。第一信号线241可以沿第一方向延伸，第二信号线242可以沿第二方向延伸。
可选地，与同一个岛区21内的各驱动电路连接的多条第一信号线241，分别位于不同层且相互交叠设置在第一桥区231范围内。
通过将连接同一岛区21内各驱动电路的多条第一信号线241设置在不同的膜层，使得这些第一信号线241可以交叠设置在第一桥区231范围内，从而可以减少第一信号线241的空间占用，压缩第一桥区231的面积，提高孔区22即透明区域的面积，提高环境光透过率。
为了进一步减少第一信号线241的面积占用，压缩第一桥区231的面积，最大化透明孔区22的面积，可选地，与同一个岛区21内的各驱动电路连接的多条第一信号线241在第二方向上完全交叠。
可选地，与同一个岛区21内的各驱动电路连接的多条第二信号线242，分别位于不同层且相互交叠设置在第二桥区232范围内。
通过将连接同一岛区21内各驱动电路的多条第二信号线242设置在不同的膜层，使得这些第二信号线242可以交叠设置在第二桥区232范围内，从而可以减少第二信号线242的空间占用，压缩第二桥区232的面积，以提高孔区22即透明区域的面积，提高环境光透过率。
为了进一步减少第二信号线242的面积占用，压缩第二桥区232的面积，最大化透明孔区22的面积，可选地，与同一个岛区21内的各驱动电路连接的多条第二信号线242在第一方向上完全交叠。
其中，第一方向与第二方向可以相互垂直。
其中，第一信号线241例如可以包括数据信号线等。第二信号线242例如可以包括栅极信号线等。

当第一信号线241的材质为金属时，可以降低第一信号线241的电阻。由于金属材质的第一信号线241不透光，为了提高显示基板的环境光透过率，可以将与同一个岛区21内的各驱动电路连接的多条第一信号线241，分别设置于不同膜层且相互交叠或完全交叠设置在第一桥区231范围内，从而可以压缩第一桥区231的面积，提高显示基板的环境光透过率。
当第一信号线241的材质为透明金属氧化物时，由于第一信号线241本身的透光特性，可以避免对环境光线造成遮挡，因此可以提高环境光透过率。
具体地，第二信号线242的材质可以包括钛、铝、钼、铜、银、镁、锂、钕、金以及铂等金属材料中的至少一种，还可以包括氧化铟锡(Indium Tin Oxide，ITO)、氧化铟锌(Indium Zinc Oxide，IZO)以及氧化石墨烯等透明金属氧化物中的至少一种，本实施例对此不作限定。例如，第二信号线242的材质为钛/铝/钛。
当第二信号线242的材质为金属时，可以降低第二信号线242的电阻。由于金属材质的第二信号线242不透光，为了提高显示基板的环境光透过率，可以将与同一个岛区21内的各驱动电路连接的多条第二信号线242，分别设置于不同膜层且相互交叠或完全交叠设置在第二桥区232范围内，从而可以压缩第二桥区232的面积，提高显示基板的环境光透过率。
当第二信号线242的材质为透明金属氧化物时，由于第二信号线242本身的透光特性，可以避免对环境光线造成遮挡，因此可以提高环境光透过率。
本公开提供了一种显示装置，包括任一项提供的显示基板。
由于该显示装置包括上述的显示基板，本领域技术人员可以理解，该显示装置具有本公开提供的显示基板的优点，这里不再赘述。
需要说明的是，本实施例中的显示装置可以为：显示面板、电子纸、手机、平板电脑、电视机、笔记本电脑、数码相框、虚拟现实设备、增强现实设备、屏下摄像头设备以及导航仪等任何具有2D或3D显示功能的产品或部件。
本公开提供了一种显示基板的驱动方法，应用于任一项提供的显示基板。参照图5或图6，该驱动方法包括：分别驱动各第一子像素31独立发光，以在虚拟四边形A内形成四个白色像素W，各白色像素W包括一个第一子像素31、一个第二子像素32和一个第三子像素33，相邻的两个白色像素W之间共用第二子像素32和/或第三子像素33。
在具体实现中，对于每一个第一子像素31，可以独立进行驱动，该第一子像素31与周围的一个第二子像素32和一个第三子像素33构成一个白色像素W。这样，可以在虚拟四边形A内形成四个白色像素W。
如图5所示，在虚拟四边形A内，每个第一子像素31对应一个白色像素W。虚拟四边形A中的各白色像素W可以独立地包括一个第一子像素31。虚拟四边形A中相邻的两个白色像素W之间可以共用第二子像素32和/或第三子像素33。
具体地，相邻的两个第一子像素31对应的两个白色像素W，可以共用位于这相邻的两个第一子像素31之间的第二子像素32或第三子像素33。
例如，在虚拟四边形A中，右下角的白色像素W(如图5中的a图所示)与左下角的白色像素W(如图5中的b图所示)共用位于右下角的第一子像素31与左下角的第一子像素31之间的第二子像素32。
在虚拟四边形A中，右上角的白色像素W(如图5中的c图所示)与左上角的白色像素W(如图5中的d图所示)共用位于右上角的第一子像素31与左上角的第一子像素31之间的第二子像素32。
在虚拟四边形A中，右下角的白色像素W(如图5中的a图所示)与右上角的白色像素W(如图5中的c图所示)共用位于右下角的第一子像素31与右上角的第一子像素31之间的第三子像素33。
在虚拟四边形A中，左下角的白色像素W(如图5中的b图所示)与左上角的白色像素W(如图5中的d图所示)共用位于左下角的第一子像素31与左上角的第一子像素31之间的第三子像素33。
在显示的过程中，每个白色像素W的亮度中心形成一个白色亮度中心C(如图5所示)。
由于第一子像素31之间的间隔较大，在虚拟四边形A中的分布较为分散，因此可以将第一子像素31设置为人眼感知较为强烈或人眼敏感度较高的颜色子像素(如绿色子像素等)，由于第一子像素31的分散度较高，因此第一子像素31与岛区21内的第二子像素32和第三子像素33混色形成的白色亮度中心C的分散度也相应提高，提高了白色亮度中心C在岛区21内的分布均匀性，避免白色亮度中心C在岛区21内局部聚集，相当于增大岛区21内白色亮度中心C的数量，从而可以提升显示画面的精细度。
另外，由于岛区21内白色亮度中心C的分布更加均匀，在岛区21的边缘也分布有白色亮度中心C，因此可以缩小分别位于相邻岛区21上的两个白色亮度中心C的间距(如图6)，从而可以缩小相邻岛区21之间的暗区间隔，减少显示画面颗粒感。
