具体实施方式
本公开实施例提供了显示基板、其驱动方法、显示装置及高精度金属掩模板。为了使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开作进一步地详细描述，显然，所描述的实施例仅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做出创造性劳动前提下所获得的所有其它实施例，都属于本公开保护的范围。
附图中各部件的形状和大小不反映真实比例，目的只是示意说明本公开内容。
本公开实施例提供的显示基板，如图1a至如1i所示，显示基板的显示区域包括第一显示子区域A1和第二显示子区域A2；其中，第一显示子区域A1内的像素分布密度大于第二显示子区域A2内的像素分布密度。
本公开实施例提供的显示基板，由于将显示区域设置为像素分布密度大(即分辨率高)的第一显示子区域和像素分布密度小(即分辨率低)的第二显示子区域。由于第二显示子区域内的像素分布密度较小，因此可以将摄像头等元件设置在第二显示子区域内，即采用降低局部像素分布密度来增加屏幕透光率的方式来提高显示基板的屏占比。
需要说明的是，像素分布密度指的可以是在单位面积中均匀设置的像素的个数。单位面积中设置的像素个数多，则像素分布密度大，分辨率高。反之，单位面积中设置的像素个数少，则像素分布密度小，分辨率低。
进一步地，本公开实施例中，像素分布密度具体计算公式：
Figure PCTCN2019078871-appb-000004
其中，ρ表示像素分布密度，x表示行方向上的显示像素数量，y表示列方向上的显示像素数量，S表示屏幕面积。
在具体实施时，在本公开实施例提供的显示基板中，第二显示子区域可以为一个或多个。并且，第一显示子区域可以为连续的区域，或者第一显示子区域也可以为不连续的区域，这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，在本公开实施例提供的显示基板中，如图1a至图1g所示，第二显示子区域A2的至少部分边与显示区域的至少部分边重合，并且，第二显示子区域A2的其余部分被第一显示子区域A1包围。这样可以将第二显示子区域A2设置在显示区域边缘。
在具体实施时，在本公开实施例提供的显示基板中，如图1h与图1i所示，第一显示子区域A1包围第二显示子区域A2设置。这样可以将第二显示子区域A2设置在显示区域内部。
进一步地，在具体实施时，可以使第二显示子区域A2的形状设置为规则的形状，例如如图1a至图1c所示，可以使第二显示子区域A2设置为矩形。其中，该矩形的顶角可以为直角或者也可以为弧形的角。如图1d所示，可以使第二显示子区域A2设置为梯形。其中，该梯形的顶角可以为正规的夹角或者也可以为弧形的角。如图1h与图1i所示，可以使第二显示子区域A2设置为圆形。当然也可以第二显示子区域A2的形状设置为不规则的形状。例如如图1e所示，可以使第二显示子区域A2设置为水滴形。当然，在实际应用中，第二显示子区域的形状可以根据第二显示子区域内设置的元件的形状进行设计，在此不作限定。
可选地，在本公开实施例提供的显示基板中，如图1a至图1i所示，第一显示子区域A1与第二显示子区域A2形成连续的显示区域，且显示区域的形状大致为矩形。这样可以通过使第一显示子区域A1与第二显示子区域A2形成互补图形，以形成连续的显示区域。进一步地，例如，显示区域的顶角均为直角，则显示区域为矩形。或者，显示区域顶角可以为弧形的角，则显示区域的形状大致为矩形。
在具体实施时，在本公开实施例提供的显示基板中，对第一显示子区域 和第二显示子区域的相对位置关系以及形状不作限定，可以根据显示基板的屏幕设计设置。以手机为例，如图1a所示，可以将第二显示子区域A2设置在第一显示子区域A1的左上角。如图1b所示，将第二显示子区域A2设置在第一显示子区域A1的右上角。如图1c至图1e所示，将第二显示子区域A2设置在第一显示子区域A1的中间靠上位置处。如图1f所示，可以使第一显示子区域A1和第二显示子区域A2沿行方向排列。其中，可以使第二显示子区域A2位于第一显示子区域A1的上侧或下侧。这样还可以在第二显示子区域A2所处的区域中设置传感器，例如进行人脸识别的传感器(例如红外传感器等)。如图1g所示，可以使第一显示子区域A1和第二显示子区域A2沿列方向排列。其中，可以使第二显示子区域A2位于第一显示子区域A1的左侧或右侧。这样还可以在第二显示子区域A2所处的区域中设置传感器，例如进行人脸识别的传感器(例如红外传感器等)。如图1h所示，将第二显示子区域A2设置在第一显示子区域A1的中间。如图1i所示，将第二显示子区域A2设置在显示区域的边角(例如左上角处)。当然，在实际应用中，第二显示子区域A2的具体位置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，在本公开实施例提供的显示基板中，第二显示子区域内的像素分布密度根据要设置在第二显示子区域内的元件以及显示需求决定，在此不作限定。例如以在第二显示子区域内设置摄像头为例，当像素分布密度太大时能够保证好的显示效果，但是影响摄像清晰度，当像素分布密度太小时，能够保证高的摄像清晰度，但是影响显示。在具体实施时，以目前显示基板能够达到的分辨率的能力，一般第二显示子区域的像素分布密度不低于第一显示子区域的像素分布密度1/4。例如，第二显示子区域的像素分布密度为第一显示子区域的像素分布密度的1/2、1/3或1/4。当然，当显示基板的分辨率可以做到更高时，第二显示子区域的像素分布密度与第一显示子区域的像素分布密度比值可以设置的更小。
在具体实施时，在本公开实施例提供的显示基板中，如图1a至图1i所示，可以使第二显示子区域A2的面积小于第一显示子区域A1的面积。当然，在 实际应用中，第二显示子区域的面积可以根据第二显示子区域内设置的元件进行设计，在此不作限定。
一般显示区内设置有像素单元，像素单元中设置有多个子像素，本公开实施例中的像素指的可以是能独立显示一个像素点的子像素组合，例如一个像素指的可以是一个像素单元。可选地，在本公开实施例提供的显示基板中，如图2至图13所示，第一显示子区域A1内包括多个相邻设置的第一像素单元10和第二像素单元20；其中，第一像素单元10包括第一子像素1和第二子像素2，第二像素单元20包括第三子像素3和第二子像素2。显示时第一显示子区域A1内的像素数量等于第一像素单元10的数量和第二像素单元20的数量之和。即第一显示子区域A1内像素排列为Pantile排列，在显示时像素单元通过借用相邻像素单元中的子像素可以实现高于物理分辨率的分辨率。
第二显示子区域A2内包括多个第三像素单元30，第三像素单元30包括相邻设置的第一子像素1、第二子像素2和第三子像素3。显示时第二显示子区域A2内的像素数量等于第三像素单元30的数量。即第二显示子区域A2内像素的物理分辨率即为其显示分辨率。另外，该实施例仅给出第二显示子区域内第三像素单元30的一种排布方式，在此不限定第二显示子区域A2内第三像素单元30的分布密度。
需要说明的是，像素单元可以是显示一个像素点的子像素组合，例如可以是红色子像素、绿色子像素以及蓝色子像素中的两个、三个、四个或更多个子像素的组合。或者，像素单元也可以是基本重复单元或像素组合，例如是红色子像素、绿色子像素以及蓝色子像素的组合。
在具体实施时，在本公开实施例提供的显示基板中，两个像素单元相邻是指该两个像素单元之间没有其它像素单元存在。两个子像素相邻设置是指在该两个子像素之间没有其它子像素存在。
需要说明的是，在本公开实施例提供的显示基板中，由于显示子区域边缘的空间局限性，第一显示子区域内子像素的排布以及第二显示子区域内子像素的排布主要是指显示子区域内部的，在显示区域边缘可能会有些子像素 的排布与其他区域不同，在此不作限定。
在具体实施时，第一子像素、第二子像素和第三子像素一般分别为红色子像素、绿色子像素和蓝色子像素中的一种。可选地，在本公开实施例提供的显示基板中，第二子像素为绿色子像素，第一子像素为红色或蓝色子像素，第三子像素为蓝色或红色子像素。
可选地，在本公开实施例提供的显示基板中，如图2至图5所示，第二显示子区域A2内的子像素与第一显示子区域A1内的部分子像素可以位于同一行。这样相当于第二显示子区域A2内子像素与第一显示子区域A1内的子像素在行方向上是对应的，不是错行设或错列设置。这样在制作时，相当于将原本在整个显示区域内规则排列的子像素掩膜中第二显示子区域内的部分子像素去掉，制作工艺相对容易实现。可选地，在本公开实施例提供的显示基板中，如图6至图13所示，第二显示子区域A2内的子像素与第一显示子区域A1内的部分子像素位于同一列。这样相当于第二显示子区域A2内子像素与第一显示子区域A1内的子像素在列方向上是对应的，不是错行设或错列设置。这样在制作时，相当于将原本在整个显示区域内规则排列的子像素掩膜中第二显示子区域内的部分子像素去掉，制作工艺相对容易实现。例如图2所示，第二显示子区域A2相比第一显示子区域A1相当于去掉一半的第二子像素2，从而分辨率为第一显示子区域A1的1/2。例如图3所示，第二显示子区域A2相比第一显示子区域A1相当于去掉3/4的第二子像素2，去掉一半第一子像素1和一半第三子像素3，从而分辨率为第一显示子区域A1的1/4。
可选地，在本公开实施例提供的显示基板中，如图2至图8所示，第二显示子区域A2内的一个第一子像素1的发光面积大致等于第一显示子区域A1内的一个第一子像素1的发光面积。第二显示子区域A2内的一个第三子像素3的发光面积大致等于第一显示子区域A1内的一个第三子像素3的发光面积。如图2至图7所示，第二显示子区域A2内的一个第二子像素2的发光面积大致等于第一显示子区域A1内的一个第二子像素2的发光面积。
在具体实施时，由于第二显示子区域的像素分布密度小于第一显示子区 域的像素分布密度，因此在显示时，第二显示子区域的亮度会比第一显示子区域的亮度低，从而在第一显示子区域和第二显示子区域的交界处会存在人眼可见的明显暗纹。可选地，为了改善该暗纹现象，在本公开实施例提供的显示基板中，如图9至图13所示，第二显示子区域A2内的一个第一子像素1的发光面积大于第一显示子区域A1内的一个第一子像素1的发光面积；第二显示子区域A2内的一个第二子像素2的发光面积大于第一显示子区域A1内的一个第二子像素2的发光面积；第二显示子区域A2内的一个第三子像素3的发光面积大于第一显示子区域A1内的一个第三子像素3的发光面积。即通过增大第二显示子区域A2内子像素的发光面积来降低第二显示子区域A2与第一显示子区域A1的亮度差异，从而减轻第二显示子区域A2与第一显示子区域A1的边界暗纹。
可选地，在本公开实施例提供的显示基板中，如图2至图5、图7至图10所示，第二显示子区域A2内，多个第三像素单元30呈矩阵排列。
可选地，在本公开实施例提供的显示基板中，如图6、图11至图13所示，第二显示子区域A2内，多个第三像素单元30呈棋盘格方式排列。即多个第三像素单元30在行方向上隔列进行设置，在列方向隔行进行设置。例如图6所示，在奇数行上，第三像素单元30设置在奇数列的位置，在偶数行上，第三像素单元30设置在偶数列的位置，从而使第三像素单元30沿行方向和沿列方向都均匀分布，从而保证第二显示子区域A2内亮度均匀。也可以例如是在奇数行上，第三像素单元30设置在偶数列的位置，在偶数行上，第三像素单元30设置在奇数列的位置，使得任意两个第三像素单元之间均间隔一定距离，间隔距离例如在行方向上可以是至少一个第三像素单元在行方向的长度，在列方向可以是至少一个第三像素单元在列方向的长度，这些本公开实施例不做限定。
可选地，在本公开实施例提供的显示基板中，如图5与图10所示，第二显示子区域A2内的第三像素单元30中，第一子像素1和第三子像素3同行设置，第二子像素2位于第一子像素1和第三子像素3所在行的相邻行，这 样使第二子像素2和第一子像素1错行设置。例如同一第三像素单元30中的第一子像素1和第三子像素3位于第一行中，第二子像素2位于第二行中。这样可以使同一第三像素单元30中的第一子像素、第二子像素和第三子像素的中心连线构成一个三角形。这样可以避免第二显示子区域内出现横向的暗亮条纹。
需要说明的是，在本公开实施例提供的显示面板中，子像素的中心是指子像素的发光区域的中心。以OLED显示面板为例，子像素一般包括由阳极层、发光层和阴极层构成的层叠结构，其中，显示时该层叠结构对应的发光区域为该子像素的发光区域。这样可以使发光区域所占用的面积作为发光面积。当然，发光面积例如也可以为由像素界定层限定的开口区所占用的面积，在此不作限定。
可选地，在本公开实施例提供的显示基板中，如图5和图10所示，同一第三像素单元30中，第二子像素2的中心在第一子像素1的中心与第三子像素3的中心之间的连线L1上的正投影，位于第一子像素1的中心与第三子像素3的中心之间。例如第二子像素2的中心在第一子像素1的中心与第三子像素3的中心之间的连线L1上的正投影位于连接L1和直线L2的交点上。这样可以使第三像素单元30中的第二子像素2的中心与第一子像素1的中心之间的距离等于第二子像素2的中心与第三子像素3的中心之间的距离，以使这三个子像素呈等腰三角形排列，可以避免第二显示子区域A2内出现纵向的暗亮条纹。
在具体实施时，第二子像素2的中心与第一子像素1的中心之间的距离以及第二子像素2的中心与第三子像素3的中心之间的距离可能并不能完全相同，在实际工艺中，由于工艺条件的限制或其他因素例如布线或过孔的设置，也可能会有一些偏差，因此各子像素的形状、位置及相对位置关系只要大致满足上述条件即可，均属于本公开的保护范围。
可选地，在本公开实施例提供的显示基板中，如图2至图4、图6至图9、图11至图13所示，第二显示子区域A2内，第三像素单元30中的第一子像 素1、第二子像素2和第三子像素3同行设置。或者，也可以同列设置，在此不作限定。
当然，在具体实施时，在本公开实施例提供的显示基板中，如图2至图4、图6至图9、图11至图13所示，第二显示子区域A2内，第三像素单元30中，第一子像素1、第二子像素2和第三子像素3同行依次设置。或者，也可以同列依次设置，在此不作限定。进一步地，当然，在具体实施时，在本公开实施例提供的显示基板中，如图2至图4、图6至图9、图11至图13所示，第二显示子区域A2内，第三像素单元30中，第一子像素1、第二子像素2和第三子像素3同行依次相邻设置，或者，也可以同列依次相邻设置，在此不作限定。
可选地，在本公开实施例提供的显示基板中，如图2、如4至图6、图12所示，第二显示子区域A2内，沿行方向相邻的两个第三像素单元30内的子像素沿行方向的排列顺序相同，沿列方向相邻的两个第三像素单元30内的子像素沿行方向的排列顺序相反。从而保证第二显示子区域A2内，在列方向上第一子像素1和第三子像素3交替排列，避免列方向发生色偏。例如图2所示，以第一行第三像素单元30为例，沿行方向上，相邻的两个第三像素单元30内的第一子像素1、第二子像素2、第三子像素3均由左向右依次排列。以第一列第三像素单元30为例，沿列方向上，奇数行中的第三像素单元30内的第一子像素1、第二子像素2、第三子像素3均由左向右依次排列。偶数行中的第三像素单元30内的第三子像素3、第二子像素2、第一子像素1均由左向右依次排列。例如图5所示，以第一行第三像素单元30为例，沿行方向上，相邻的两个第三像素单元30内的第一子像素1、第三子像素3、第二子像素2均呈倒三角形排列。以第一列第三像素单元30为例，沿列方向上，奇数行中的第三像素单元30内的第一子像素1、第三子像素3、第二子像素2均呈倒三角形排列。偶数行中的第三像素单元30内的第三子像素3、第一子像素1、第二子像素2均呈倒三角形排列。
在具体实施时，本公开实施例提供的显示基板中，如图2、图7至图11 所示，第二显示子区域A2内，可以使每个第三像素单元内的子像素的排列顺序相同。
在具体实施时，本公开实施例提供的显示基板中，如图13所示，第二显示子区域A2内，同一列中每个第三像素单元30内的子像素的排列顺序相同，并且相邻两列中第三像素单元30内的子像素的排列顺序相反。例如，奇数列中每个第三像素单元30内的第一子像素1、第二子像素2、第三子像素3均由左向右依次排列。偶数列中每个第三像素单元30内的第三子像素3、第二子像素2、第一子像素1均由左向右依次排列。
在具体实施时，本公开实施例提供的显示基板中，如图2至图6以及图8至图13所示，第二显示子区域A2内，第一子像素1、第二子像素2、第三子像素3的形状大致一致。
在具体实施时，本公开实施例提供的显示基板中，第二显示子区域内，一个第二子像素的发光面积小于或大致等于一个第一子像素的发光面积，一个第二子像素的发光面积小于或大致等于一个第三子像素的发光面积。例如，如图2至图6所示，第二显示子区域A2内一个第二子像素2的发光面积大致等于一个第一子像素1的发光面积，一个第二子像素2的发光面积大致等于一个第三子像素3的发光面积。如图7至图13所示，第二显示子区域A2内一个第二子像素2的发光面积小于一个第一子像素1的发光面积，一个第二子像素2的发光面积小于一个第三子像素3的发光面积。当然，第二显示子区域内的一个第二子像素的发光面积、一个第一子像素的发光面积以及一个第三子像素的发光面积的关系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，本公开实施例提供的显示基板中，如图2至图13所示，第二显示子区域A2内，一个第一子像素1的发光面积大致等于一个第三子像素3的发光面积。
可选地，本公开实施例提供的显示基板中，如图2至图13所示，第一显示子区域A1内第一像素单元10和第二像素单元20可以排列为任意一种 Pantile排列方式，在此不作限定。
可选地，本公开实施例提供的显示基板中，如图2至图13所示，在第一显示子区域A2内，第一像素单元10和第二像素单元20沿列方向交替排列，第一像素单元10和第二像素单元20沿行方向交替排列。
可选地，在本公开实施例提供的显示基板中，如图2至图6所示，在第一显示子区域A1内，第一像素单元10内第二子像素2与第一子像素1同行排列；第二像素单元20内第二子像素2与第三子像素3同行排列。并且，针对沿行方向上相邻的第一像素单元10和第二像素单元20，第一像素单元10中的第二子像素2与第二像素单元20中的第二子像素2不直接相邻。例如，针对行方向上相邻的第一像素单元10和第二像素单元20，第一像素单元10中的第二子像素2与第二像素单元20中的第二子像素之间间隔着第三子像素3。当然，上述实施方式还可以有其他实施方式，在此不作赘述。
进一步地，在本公开实施例提供的显示基板中，如图2至图6所示，第一显示子区域A2内，一个第一子像素1的发光面积、一个第二子像素2的发光面积以及一个第三子像素3的发光面积可以大致相同。
可选地，在本公开实施例提供的显示基板中，如图7至图13所示，在第一显示子区域A1内，第一像素单元10内第二子像素2与第一子像素1错行排列且错列排列；第二像素单元20内第二子像素2与第三子像素3同行排列。并且，以沿列方向相邻的第一像素单元10和第二像素单元20为一像素组100，在同一像素组100内，第一像素单元10内第二子像素2与第二像素单元20内的第三子像素3同行排列，且第一像素单元10内第二子像素2与第二像素单元20内的第二子像素2位于同一列。
进一步地，在本公开实施例提供的显示基板中，如图7至图12所示，同一像素组100内，两个第二子像素2沿列方向上相邻设置，且两个第二子像素2关于行方向对称，即使同一像素组100内的两个第二子像素2镜像设置。进一步地，在第一显示子区域A1内，当第二子像素2为绿色子像素时，两个第二子像素2的发光面积小于一个第一子像素1的发光面积，且两个第二子 像素2的发光面积小于一个第三子像素3的面积，这是因为绿色子像素的发光效率高于其它颜色子像素的发光效率。
可选地，本公开实施例提供的显示基板中，如图2至图13所示，第一显示子区域内，每个第一像素单元10内的子像素的排列顺序相同，每个第二像素单元20内的子像素的排列顺序相同。例如，如图2至图6所示，每个第一像素单元10内第一子像素1、第二子像素2均由左向右依次排列。每个第二像素单元20内第三子像素3、第二子像素2均由左向右依次排列。如图7至图13所示，每个第二像素单元20内第三子像素3、第二子像素2均由左向右依次排列。每个第一像素单元10内第一子像素1、第二子像素2均由左上向右下方向依次排列。
可选地，在本公开实施例提供的显示基板中，第一显示子区域内，一个第二子像素的发光面积不大于一个第一子像素的发光面积，一个第二子像素的发光面积不大于一个第三子像素的发光面积。例如，如图2至图6所示，第一显示子区域A1内，一个第二子像素2的发光面积大致等于一个第一子像素1的发光面积，一个第二子像素2的发光面积大致等于一个第三子像素3的发光面积。如图7至图13所示，第一显示子区域A1内，一个第二子像素2的发光面积小于一个第一子像素1的发光面积，一个第二子像素2的发光面积小于一个第三子像素3的发光面积。这是由于在第一显示子区域A1内，第一子像素1的数量与第三子像素3的数量相同，而第二子像素2的数量为第一子像素1的一倍，因此可以将第二子像素2的发光面积做小。
可选地，在本公开实施例提供的显示基板中，如图2至图13所示，第一显示子区域A1内，一个第一子像素1的发光面积大致等于一个第三子像素3的发光面积。
具体地，在本公开实施例提供的显示基板中，第一显示子区域内，对第一子像素、第二子像素以及第三子像素的形状不作限定，可以是规则的形状，也可以是不规则的形状。在具体实施时，一般规则的形状从工艺角度考虑比较容易实现。
具体地，在本公开实施例提供的显示基板中，第二显示子区域内，对第一子像素、第二子像素以及第三子像素的形状不作限定，可以是规则的形状，也可以是不规则的形状。在具体实施时，一般规则的形状从工艺角度考虑比较容易实现。
可选地，在本公开实施例提供的显示基板中，如图7至图12所示，同一像素组100内，第一子像素1和第三子像素3的形状一致，且两个第二子像素2组合的形状与第一子像素1或者第三子像素3的形状一致。
可选地，在本公开实施例提供的显示基板中，第一子像素的形状为矩形和六边形中的至少一种。例如，如图2至图6所示，第一显示子区域A1和第二显示子区域A2内，第一子像素1的形状均为矩形。如图7至图12所示，第一显示子区域A1和第二显示子区域A2内，第一子像素1的形状均为六边形。当然，第一子像素的形状也可以为圆角图形，或者为椭圆形等，在此不作限定。
可选地，在本公开实施例提供的显示基板中，如图7至图12所示，第一显示子区域A1内，第一子像素1和第三子像素3的形状均为六边形，两个第二子像素2组合在一起的形状为一个六边形。
可选地，在本公开实施例提供的显示基板中，第二显示子区域内的第一子像素与第三子像素中的至少一种子像素的形状与第一显示子区域中的第一子像素的形状大致一致。例如，如图2至图13所示，第二显示子区域A2内的第一子像素1的形状与第一显示子区域A1中的第一子像素1的形状大致一致。如图2至图13所示，第二显示子区域A2内的第三子像素3的形状与第一显示子区域A1中的第一子像素1的形状大致一致。如图2至图13所示，第二显示子区域A2内的第一子像素1的形状和第三子像素3的形状分别与第一显示子区域A1中的第一子像素1的形状大致一致。
可选地，在本公开实施例提供的显示基板中，第一显示子区域中的第一子像素和第二子像素中的一种子像素的形状与第二显示子区域内的第二子像素的形状大致一致。例如，如图2至图6以及图8至图13所示，第一显示子 区域A1中的第一子像素1的形状与第二显示子区域A2内的第二子像素2的形状大致一致。如图7所示，第一显示子区域A1中的第二子像素2的形状与第二显示子区域A2内的第二子像素2的形状大致一致。
需要说明的是，以同一个子区域中各第一子像素1、各第二子像素2、各第三子像素3的形状大致一致为例，这三种子像素的形状大致一致，当时这三种子像素的发光面积可以不同。例如图10所示，第二显示子区域A2中，第二子像素2的发光面积小于第一子像素1的发光面积，且第二子像素2的发光面积小于第三子像素3的发光面积。并且，在实际应用中，例如也可以根据蓝色子像素的发光面积大于红色子像素的发光面积大于绿色子像素的发光面积，或者蓝色子像素的发光面积大于绿色子像素的发光面积大于红色子像素的发光面积的实施方式进行设置，在此不作限定。
需要说明的是，在本公开实施例提供的显示基板中，子像素的形状是指子像素的发光区域的形状。
可选地，在本公开实施例提供的显示基板中，如图7至图12所示，在第一显示子区域A1内，当第二子像素2为绿色子像素时，两个第二子像素2的发光面积小于一个第一子像素1的面积，且两个第二子像素2的发光面积小于一个第三子像素3的面积，这是因为绿色子像素的发光效率高于其它颜色子像素的发光效率。
可选地，在本公开实施例提供的显示基板中，如图7至图12所示，第二显示子区域A2内，当第二子像素2为绿色子像素时，第二子像素2的发光面积小于第一子像素1的发光面积，第二子像素2的发光面积小于第三子像素3的发光面积。
在具体实施时，本公开实施例提供的显示基板在显示时一般以第一显示子区域内的行为单位进行逐行扫描。例如图15所示，当第一显示子区域A1和第二显示子区域A2沿行方向相邻时，栅极驱动电路GOA1～GOA5逐行输出信号，但是对于第二显示子区域A2，仅需要GOA1、GOA3和GOA5输出信号。
基于同一发明构思，本公开实施例还提供了驱动上述任一显示基板的驱动方法，如图14所示，包括：
S1301、接收原始图像数据；
S1302、对于第一显示子区域内的各子像素，根据该子像素在原始图像数据中对应的子像素的初始灰阶值，确定该子像素的目标灰阶值；对于第二显示子区域内的各子像素，根据子像素的发光面积、第二显示子区域的像素分布密度，以及该子像素所在区域在原始图像数据中对应的子像素的初始灰阶值，确定该子像素的目标灰阶值；
S1303、驱动显示基板内的各子像素根据其目标灰阶值进行显示。
具体地，对于第一显示子区域内的子像素，当第一显示子区域内一个物理像素对应图像数据中的一个像素时，一般子像素的目标灰阶值为其初始灰阶值。而当第一显示区域内物理像素少于图像数据中的像素数量时，在显示时就存在子像素的借用关系，因此一个子像素可能对应图像数据中的两个或者更多的像素，因此子像素的目标灰阶值就需要根据其在原始图像数据中对应的子像素的初始灰阶值进行换算。
对于第二显示子区域内的各子像素，由于分辨率低，显示时一个物理像素就对应图像数据中的一个像素，一般情况下子像素的目标灰阶值为其初始灰阶值。但是这样会存在一个问题，由于第二显示子区域的分辨率低，若直接按照初始灰阶值进行显示，第二显示子区域和第一显示子区域内的亮度会存在较大的差异，因此第二显示子区域和第一显示子区域的边界会存在明显的暗纹。为了解决该问题，因此本公开实施例提供的驱动器，根据子像素的发光面积、第二显示子区域的像素分布密度，对第二显示子区域内子像素的灰阶进行调整。例如，子像素的发光面积越大，第二显示子区域的整体亮度越高，以及第二显示子区域内分布的子像素数量越多，第二显示子区域的整体亮度也会越高。
需要说明的是，一个物理像素一般至少包括RGB三个子像素。
在具体实施时，当第一显示子区域内，像素排列为Pantile排列时，由于 第一子像素和第三子像素都会被借用，因此，在显示时一般一个第一子像素会在图像数据中对应两个像素，一个第三子像素会在图像数据中对应两个像素，第二子像素没被借用，因此一个第二子像素一般对应图像数据中的一个像素。
因此，可选地，在本公开实施例提供的驱动方法中，对于第一显示子区域内的各子像素，确定该子像素的目标灰阶值，具体可以包括：
第一子像素根据公式：
Figure PCTCN2019078871-appb-000005
确定其对应的目标灰阶值X；其中，Gamma表示显示基板的伽马值，x 1和x 2分别为第一子像素在原始图像数据中对应的两个第一子像素的初始灰阶值；
第二子像素的目标灰阶值Y等于第二子像素在原始图像数据中对应的一个第二子像素的初始灰阶值y；
第三子像素根据公式：
Figure PCTCN2019078871-appb-000006
确定其对应的目标灰阶值Z；其中，z 1和z 2分别为第三子像素在原始图像数据中对应的两个第三子像素的初始灰阶值。
在具体实施时，为了改善第二显示子区域与第一显示子区域的边界暗纹，可以对第二显示子区域的亮度进行适当的调整。亮度与发光面积和像素分布密度均成正比。
因此，可选地，在本公开实施例提供的驱动方法中，对于第二显示子区域内的各子像素，确定该子像素的目标灰阶值，具体可以包括：
子像素根据公式：
Figure PCTCN2019078871-appb-000007
确定其对应的目标灰阶值X；
其中，n取1～N的任意整数，N为子像素在原始图像数据中对应的子像素的数量，Gamma表示显示基板的伽马值，s表示子像素在第一显示区内的 发光面积与子像素在第二显示子区域内的发光面积比值，ρ表示第一显示子区域内的像素分布密度与第二显示子区域内像素分布密度的比值，k为误差调节系数，x n为子像素在原始图像数据中对应的第n个子像素的初始灰阶值。
在具体实施时，误差调节系数k可以根据显示基板的实际显示效果进行调整，在此不作限定。
在具体实施时，假设第二显示子区域内，单位面积内有m个第三像素单元，对应区域的图像数据中有j个像素，那么一个第三像素单元对应图像数据中的j/m个像素，即N＝j/m。在确定子像素的目标灰阶时，该子像素的目标灰阶值可以根据其对应的N个子像素中的任意一个或多个子像素来确定。例如N＝4，那么一个子像素可以根据其对应的图像素中的4个子像素中的任意一个或多个子像素的初始灰阶值进行确定。例如根据其中一个子像素的初始灰阶值进行确定，那么X＝k*s*ρ*x i，其中x i表示4个子像素中的任意一个子像素的初始灰阶值。例如根据其中两个子像素的初始灰阶值进行确定，那么
Figure PCTCN2019078871-appb-000008
其中x 1和x 2表示4个子像素中的任意两个子像素的初始灰阶值。例如根据其中三个子像素的初始灰阶值进行确定，那么
Figure PCTCN2019078871-appb-000009
其中x 1、x 2和x 3表示4个子像素中的任意三个子像素的初始灰阶值。例如根据四个子像素的初始灰阶值进行确定，那么
Figure PCTCN2019078871-appb-000010
其中x 1、x 2、x 3和x 4表示4个子像素的初始灰阶值。
基于同一发明构思，本公开实施例还提供了显示装置，包括本公开实施例提供的上述任一显示基板。该显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。该显示装置的实施可以参见上述显示基板的实施例，重复之处不再赘述。
可选地，在本公开实施例提供的显示装置中，还包括用于驱动该显示基板的驱动器，所述显示基板的驱动器例如可以为IC(Integrated Circui，集成电路)，或者外接的CPU(Central Processing Unit，中央处理器)、微处理器等。其中，驱动器具体用于：
接收原始图像数据；
对于第一显示子区域内的各子像素，根据其在原始图像数据中对应的子像素的初始灰阶值，确定该子像素的目标灰阶值；
对于第二显示子区域内的各子像素，根据子像素的发光面积、第二显示子区域的像素分布密度，以及该子像素所在区域在原始图像数据中对应的子像素的初始灰阶值，确定该子像素的目标灰阶值；
驱动显示基板内的各子像素根据其目标灰阶值进行显示。
可选地，在本公开实施例提供的显示装置中，驱动器可以通过如下方法对第一显示子区域内的各子像素，确定该子像素的目标灰阶值，具体为：
对于第一显示区域内的第一子像素，根据公式：
Figure PCTCN2019078871-appb-000011
确定其对应的目标灰阶值X；其中，Gamma表示显示基板的伽马值，Gamma一般为2.2，x 1和x 2分别为第一子像素在原始图像数据中对应的两个第一子像素的初始灰阶值；
第二子像素的目标灰阶值Y等于第二子像素在原始图像数据中对应的一个第二子像素的初始灰阶值y；
对于第一显示区域内的第三子像素，根据公式：
Figure PCTCN2019078871-appb-000012
确定其对应的目标灰阶值Z；其中，z 1和z 2分别为第三子像素在原始图像数据中对应的两个第三子像素的初始灰阶值。
在具体实施时，为了改善第二显示子区域与第一显示子区域的边界暗纹，可以对第二显示子区域的亮度进行适当的调整。亮度与发光面积和像素分布 密度均成正比。
因此，可选地，在本公开实施例提供的显示装置中，驱动器可以通过如下方法对第二显示子区域内的各子像素，确定该子像素的目标灰阶值，具体为：
子像素根据公式：
Figure PCTCN2019078871-appb-000013
确定其对应的目标灰阶值X；
其中，n取1～N的任意整数，N为子像素在原始图像数据中对应的子像素的数量，Gamma表示显示基板的伽马值，s表示子像素在第一显示区内的发光面积与子像素在第二显示子区域内的发光面积比值，ρ表示第一显示子区域内的像素分布密度与第二显示子区域内像素分布密度的比值，k为误差调节系数，x n为子像素在原始图像数据中对应的第n个子像素的初始灰阶值。
在具体实施时，误差调节系数k可以根据显示基板的实际显示效果进行调整，在此不作限定。
具体地，本公开实施例提供的驱动方法可以参见上述显示装置中驱动器的实施，在此不作赘述。
在具体实施时，在本公开实施例提供的显示装置中，驱动器将各子区域内子像素的目标灰阶值的算法均集成在IC中。在显示时，驱动器根据接收的图像数据确定出各子像素对应的目标灰阶值，驱动显示基板根据目标灰阶值进行显示。
进一步地，显示基板根据目标灰阶值进行显示之前，为了提高亮度均匀性，一般还需要进行Demura算法处理。具体Demura算法可参考现有技术，在此不作详述。
基于同一发明构思，本公开实施例还提供了高精度金属掩模板，用于制作本公开实施例提供的上述任一显示基板，该高精度金属掩模板包括：多个开口区域，所开口区域与第一子像素，第二子像素或第三子像素的形状和位 置对应。
在具体实施时，子像素一般包括阳极层、发光层和阴极层，发光层一般采用上述高精度金属掩模板进行蒸镀。以图12所示的显示基板为例，其中用于形成第一子像素的高精度金属掩模板中，如图16所示，开口区域01与显示基板中第一子像素1的发光层的形状和位置对应。并且，由于工艺限制，开口区域01的面积一般会大于对应的发光层的面积。用于形成第二子像素的高精度金属掩模板以及用于形成第三子像素的高精度金属掩模板的原理与第一子像素相似，在此不作赘述。
本公开实施例提供的上述显示基板、其驱动方法、显示装置及高精度金属掩模板，由于将显示区域设置为像素分布密度大(即分辨率高)的第一显示子区域和像素分布密度小(即分辨率低)的第二显示子区域。由于第二显示子区域内的像素分布密度较小，因此可以将摄像头等元件设置在第二显示子区域内，即采用降低局部像素分布密度来增加屏幕透光率的方式来提高显示基板的屏占比。并且，该显示基板在驱动时，由于根据第二显示子区域内子像素的发光面积和像素分布密度对第二显示子区域的子像素的灰阶值进行了调整，因此可以补偿由于第一显示子区域和第二显示子像素的像素分布密度不一致导致的第二显示子区域和第一显示子区域内的亮度会存在较大的差异，从而减轻第二显示子区域和第一显示子区域的边界存在的暗纹，实现全屏均匀显示。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
