具体实施方式
本公开实施例提供的显示基板、其显示方法、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至图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；如图2至图7所示，第二显示子区域A2内设置有均匀分布的多个子像素。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、传感器、听筒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。并且在第二显示子区域内子像素分布均匀，可以保证第二显示子区域内亮度分布均匀。
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 PCTCN2019078879-appb-000001
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，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。
可选地，在本公开实施例提供的显示基板中，第二显示子区域的像素分布密度一般设置为第一显示子区域的像素分布密度的1/2至1/8。在具体实施时，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大约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7所示，第二显示子区域A2包括多个第一子像素1、多个第二子像素2和多个第三子像素3；相同颜色的子像素的中心均匀分布。即第一子像素1的中心均匀分布，第二子像素2的中心均匀分布，第三子像素2的中心均匀分布。保证显示的均匀性。
可选地，在本公开实施例提供的显示基板中，如图2至图7所示，沿行方向上相同颜色的子像素等间距排列，沿列方向上相同颜色的子像素的等间距排列。

可选地，在本公开实施例提供的显示基板中，如图2至图5、图7所示，相邻列中相同颜色的子像素呈错位排列，且同列中相邻两个颜色相同的子像素的中心距离相邻列中与其相邻的同颜色的子像素的中心的距离相等。以图4为例，在第二显示子区域A2内，第1列的第1个第一子像素1是位于第2列的第1个第一子像素1和第2个第一子像素1的中心连线上。
需要说明的是，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7所示，第二显示子区域A2内设置有第一子像素1、第二子像素2和第三子像素3，其中，第一子像素1在第二显示子区域A2内均匀分布，第二子像素2在第二显示子区域A2内均匀分布，第三子像素3在第二显示子区域A2内均匀分布。

可选地，在本公开实施例提供的显示基板中，如图2至图7所示，第二显示子区域A2内包括矩阵排列的多个第三像素单元30，第三像素单元30包括：第一子像素1、第二子像素2以及第三子像素3；其中，同一第三像素单元30中，第一子像素1和第三子像素3同行且相邻设置，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。这样可以使第二显示子区域A2内，第三像素单元30中三个子像素呈三角形排列。以第一行第三像素单元30为例，该第三像素单元30中的第一子像素1和第三子像素3位于子像素行中的第一行，第二子像素2位于子像素行中的第二行。
可选地，在本公开实施例提供的显示基板中，针对第二显示子区域内的第一子像素、第二子像素以及第三子像素中的同一种颜色子像素，子像素的中心均匀分布。例如，如图2至图7所示，第二显示子区域A2内的第一子像素1的中心均匀分布。第二显示子区域A2内的第二子像素2的中心均匀分布。第二显示子区域A2内的第三子像素3的中心均匀分布。
可选地，在本公开实施例提供的显示基板中，针对第二显示子区域内的第一子像素、第二子像素以及第三子像素中的同一种颜色子像素，子像素沿行方向上等间距排列且沿列方向上等间距排列。例如，如图2至图7所示，第二显示子区域A2内的第一子像素1沿行方向上等间距排列且沿列方向上等间距排列。第二显示子区域A2内的第二子像素2沿行方向上等间距排列且沿 列方向上等间距排列。第二显示子区域A2内的第三子像素3沿行方向上等间距排列且沿列方向上等间距排列。
可选地，在本公开实施例提供的显示基板中，针对第二显示子区域内的第一子像素、第二子像素以及第三子像素中的同一种颜色子像素，子像素在相邻行中呈错位排列，且同行中相邻两个子像素的中心分别与相邻行中同一个最近邻的子像素的中心的距离相等。例如，如图2至图7所示，第二显示子区域A2内的第一子像素1在相邻行中呈错位排列，且同行中相邻两个第一子像素1的中心分别与相邻行中同一个最近邻的第一子像素1的中心的距离相等。其余同理，在此不作赘述。
可选地，在本公开实施例提供的显示基板中，针对第二显示子区域内的第一子像素、第二子像素以及第三子像素中的同一种颜色子像素，子像素在相邻列中呈错位排列，且同列中相邻两个子像素的中心分别与相邻列中同一个最近邻的子像素的中心的距离相等。例如，如图2至图7所示，第二显示子区域A2内的第一子像素1在相邻列中呈错位排列，且同列中相邻两个第一子像素1的中心分别与相邻列中同一个最近邻的第一子像素1的中心的距离相等。其余同理，在此不作赘述。
可选地，在本公开实施例提供的显示基板中，如图2与图3以及图5至图7所示，第二显示子区域A2内，同一列第三像素单元30的子像素排列方式相同。以使列方向上，每一列第三像素单元30的排列方式相同，保证显示的均匀性。
可选地，在本公开实施例提供的显示基板中，如图4所示，第二显示子区域A2内，同一列中相邻的两个第三像素单元30的子像素排列方式也可以相反。以同一列中的第一行第三像素单元30和第二行第三像素单元30为例，第一行第三像素单元30以第三子像素3、第一子像素1以及第二子像素2的顺序构成三角形。第二行第三像素单元30以第一子像素1、第三子像素3以及第二子像素2的顺序构成三角形。
可选地，在本公开实施例提供的显示基板中，如图2至图7所示，第二 显示子区域A2内，第三像素单元30中，第二子像素2与第一子像1的中心之间的距离等于第二子像素2与第三子像素3的中心之间的距离。即第三像素单元30中，第二子像素2的中心，第一子像1的中心和第三子像素3的中心构成等腰三角形。从而保证第三像素单元30的像素发光中心在等腰三角形的中心。
可选地，在本公开实施例提供的显示基板中，如图2至图7所示，针对第二显示子区域A2内沿行方向相邻的两个第三像素单元30，一个第三像素单元30中的第一子像素1和第三子像素3以及另一个第三像素单元30中的第二子像素2位于同一行。这样在显示时，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为其显示分辨率。并且，在第二显示子区域A2内，第三像素单元30中三个子像素呈三角形排列，且沿行方向相邻的两个第三像素单元30一个为倒置放的三角形，一个为正向放置的三角形，从而避免第二显示子区域A2内，有的行上子像素数量多，有的行上子像素数量少，避免产生显示不均匀。
可选地，在本公开实施例提供的显示基板中，如图3至图7所示，第二显示子区域A2中的每个子像素均匀排列，以呈棋盘格方式排列。
可选地，在本公开实施例提供的显示基板中，如图4所示，第二显示子区域A2内的同一第三像素单元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，第二子像素的中心与第一子像素的中心之间的距离和第二子像素的中心与第三子像素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5、图7所示，沿行方向相邻的第三像素单元30中，相同颜色的子像素不相邻。即沿行方向相邻的两个第三像素单元30中，一个第三像素单元30中的第一子像素1和另一个第三像素单元30中的第一子像素1不相邻。这样避免在第二显示子区域A2内，由于相邻两列子像素的颜色一样而发生色偏现象。当然，如图6所示，也可以使沿行方向相邻的第三像素单元30中，相同颜色的子像素相邻。即沿行方向相邻的两个第三像素单元30中，一个第三像素单元30中的第三子像素3和另一个第三像素单元30中的第三子像素3相邻。
可选地，在本公开实施例提供的显示基板中，如图2至图7所示，第二显示子区域A2内，一个第一子像素1、一个第二子像素2以及一个第三子像素3的发光面积大致相同。这样可以使发光均匀。当然，在具体实施时，由于不同子像素的发光效率不相同，在第二显示子区域A2内，第一子像素1、第二子像素2和第三子像素3的发光面积也可以不相同，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至图7所示，第二显示子区域A2内，一个第一子像素1、一个第二子像素2以及一个第三子像素3的形状大致一致。这样可以降低工艺制备难度。

在具体实施时，在本公开实施例提供的显示面板中，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面板中，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和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，在显示子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。
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。以有机发光二极管(Organic Light-Emitting Diode，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。
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7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Pentile排列方式，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至图7所示，在第一显示子区域A1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与图3所示，第一显示子区域A1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。
进一步地，在本公开实施例提供的显示基板中，如图2与图3所示，针对同一列中的各第一像素单元10和各第二像素单元20，各第一像素单元10中的第二子像素2与各第二像素单元20中的第二子像素2位于同一列。例如，以第一列为例，各第一像素单元10中的第二子像素2与各第二像素单元20中的第二子像素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2与图3所示，第一显示子区域A1内，一个第一子像素1的形状、一个第二子像素2的形状以及一个第三子像素3的形状可以大致相同。可选地，第一显示子区域A1内，第一子像素1的形状可以为矩形。可选地，第一显示子区域A1内，第二子像素2的形状也可以为矩形。可选地，第一显示子区域A1内，第三子像素3的形状也可以为矩形。
可选地，在本公开实施例提供的显示基板中，如图4至图7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错行排列且错列排列。并且沿行方向相邻的第一像素单元10和第二像素单元20中，两个第二子像素2不相邻。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，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内的第二子像素2位于同一列。即相邻两行像素单元在列方向上错开半列。
进一步地，在本公开实施例提供的显示基板中，如图4至图7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，在本公开实施例提供的显示基板中，如图4至图7所示，第一显示子区域A1内，以沿列方向相邻的两个第二子像素2为一第二子像素组200；第一显示子区域A1内沿列方向相邻的两个第二子像素组200之间的间距等于第二显示子区域A2内沿列方向相邻的两个第二子像素2之间的距离。

可选地，在本公开实施例提供的显示基板中，如图2和图3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。即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，不是错行设置，从而保证第二显示子线区域A2内的子像素和第一显示子区域A1内的子像素，在行方向上保持一致，有利于显示基板的布线。
可选地，在本公开实施例提供的显示基板中，如图4至图7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列。即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，不是错列设置，从而保证第二显示子线区域A2内的子像素和第一显示子区域A1内的子像素，在列方向上保持一致，有利于显示基板的布线。
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一显示子区域内的第一子像素位于同一列和同一行中的至少一种。 例如，如图6与图7所示，第二显示子区域A2内的第一子像素1与第一显示子区域A1内的第一子像素1位于同一列。从而保证第二显示子区域A2内的第一子像素1与第一显示子区域A1内的第一子像素1在列方向上保持一致。如图2与图3所示，第二显示子区域A2内的第一子像素1与第一显示子区域A1内的第一子像素1位于同一行。从而保证第二显示子区域A2内的第一子像素1与第一显示子区域A1内的第一子像素1在行方向上保持一致。当然，也可以使第二显示子区域A2内的第一子像素1与第一显示子区域A1内的第一子像素1位于同一行，以及第二显示子区域A2内的第一子像素1与第一显示子区域A1内的第一子像素1位于同一列。
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二子像素与第一显示子区域内的第二子像素位于同一列和同一行中的至少一种。例如，如图2与图3所示，第二显示子区域A2内的第二子像素2与第一显示子区域A1内的第二子像素2位于同一行。如图4至图7所示，第二显示子区域A2内的第二子像素2与第一显示子区域A1内的第二子像素2位于同一列。从而保证第二显示子区域A2内的第二子像素2与第一显示子区域A1内的第二子像素2在列方向上保持一致。并且，但由于在该显示基板中，第二子像素2为像素单元的发光像素中心，因此，可以保证第二显示子区域内的发光像素中心与第一显示子区域内的发光像素中心在行方向上保持一致。当然，也可以使第二显示子区域内的第二子像素与第一显示子区域内的第二子像素位于同一列，以及第二显示子区域内的第二子像素与第一显示子区域内的第二子像素位于同一行。
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三子像素与第一显示子区域内的第三子像素位于同一列和同一行中的至少一种。例如，如图6和图7所示，第二显示子区域A2内的第三子像素3与第一显示子区域A1内的第三子像素3位于同一列。从而保证第二显示子区域A2内的第三子像素3与第一显示子区域A1内的第三子像素3在列方向上保持一致。如图2和图3所示，第二显示子区域A2内的第三子像素3与第一显示子区域 A1内的第三子像素3位于同一行。从而保证第二显示子区域A2内的第三子像素3与第一显示子区域A1内的第三子像素3在行方向上保持一致。当然，也可以使第二显示子区域内的第三子像素与第一显示子区域内的第三子像素位于同一列，以及第二显示子区域内的第三子像素与第一显示子区域内的第三子像素位于同一行。
可选地，在本公开实施例提供的显示基板中，如图5至图7所示，第一显示子区域A1内沿列方向相邻的两个第一子像素1之间的间距等于第二显示子区域A2内沿列方向相邻的两个第一子像素1之间的距离；
第一显示子区域A1内沿列方向相邻的两个第三子像素3之间的间距等于第二显示子区域A2内沿列方向相邻的两个第三子像素3之间的间距；

需要说明的是，这里的行方向是指以一行子像素为单位进行说明的。另外，在本公开实施例提供的密度比值，均为大致的比值范围，在具体实施时，密度比值可能不是整数。
可选地，在本公开实施例提供的显示基板中，如图4至图7所示，第一显示子区域A1内，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。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。
需要说明的是，形状一致是指子像素的发光区域的形状相似，但是面积可以相同，也可以不相同。子像素的发光面积可以根据子像素的发光效率进行设置，在此不作限定。
需要说明的是，在本公开实施例提供的显示面板中，子像素的形状是指子像素的发光区域的形状。

S902、对于第一显示子区域内的像素，根据其在原始图像数据中对应的像素的灰阶值进行显示；对于第二显示子区域内的像素，根据第一显示子区域的像素分布密度和第二显示子区域的像素分布密度的比值，确定一个像素在原始图像数据中对应的像素的数量N；并根据该像素所在的位置在原始图像数据中对应的N个像素中的其中一个像素或者多个像素的灰阶值进行显示。
在具体实施时，根据前述像素分布密度公式，当第一显示子区域的像素分布密度和第二显示子区域的像素分布密度的比值为n时，第二显示子区域内一个像素，在原始图像数据中对应4个像素，即N＝n*n。
可选地，在本公开实施例提供的显示方法中，对于第二显示子区域内的像素，根据该像素所在的位置在原始图像数据中对应的N个像素中的多个像素的平均灰阶值进行显示。例如N＝4，即第二显示子区域内的各像素，在原始图像数据中分别对应4个像素。那么对于第二显示子区域内的每一个像素，可以根据其在原始图像数据中对应的4个像素中的k个像素的平均灰阶值进行显示，k＝2、3或4。以k＝4为例，假设第二显示子区域内的像素包括第一子像素，第二子像素和第三子像素，那么在显示时第一子像素对应的灰阶值X1＝(x1+x2+x3+x4)/4，其中，x1～x4分别代表第二显示子区域内的像素其在原始图像数据中对应的4个像素中的各第一子像素的灰阶值；同理在显示时第二子像素对应的灰阶值Y1＝(y1+y2+y3+y4)/4，其中，y1～y4分别代表第二显示子区域内的像素其在原始图像数据中对应的4个像素中的各第二子 像素的灰阶值；在显示时第三子像素对应的灰阶值Z1＝(z1+z2+z3+z4)/4，其中，z1～z4分别代表第二显示子区域内的像素其在原始图像数据中对应的4个像素中的各第三子像素的灰阶值。
可选地，在本公开实施例提供的显示面板中，对于第二显示子区域内的像素，根据该像素所在的位置在原始图像数据中对应的N个像素中亮度最高的像素的灰阶值进行显示。
可选地，在本公开实施例提供的显示面板中，对于第二显示子区域内的像素，根据该像素所在的位置在原始图像数据中对应的N个像素中亮度值为中间值的像素的灰阶值进行显示。
可选地，在本公开实施例提供的显示面板中，对于第二显示子区域内的像素，根据该像素所在的位置在原始图像数据中对应的N个像素以及第二显示子区域内的该像素与原始图像数据N个像素的相对位置关系进行显示。
同样以N＝4为例，即第二显示子区域内的各像素，在原始图像数据中分别对应4个像素，假设第二显示子区域内的像素包括第一子像素，第二子像素和第三子像素，那么在显示时第一子像素对应的灰阶值X1＝(k1*x1+k2*x2+k3*x3+k4*x4)/4，其中，x1～x4分别代表第二显示子区域内的像素其在原始图像数据中对应的4个像素中的各第一子像素的灰阶值；同理在显示时第二子像素对应的灰阶值Y1＝(k1*y1+k2*y2+k3*y3+k4*y4)/4，其中，y1～y4分别代表第二显示子区域内的像素其在原始图像数据中对应的4个像素中的各第二子像素的灰阶值；在显示时第三子像素对应的灰阶值Z1＝(k1*z1+k2*z2+k3*z3+k4*z4)/4，其中，z1～z4分别代表第二显示子区域内的像素其在原始图像数据中对应的4个像素中的各第三子像素的灰阶值。其中，k1～k4为权重系数，由第二显示区域内该像素所在的位置与原始图像数据中对应的4个像素中各像素的距离决定，距离越大，权重系数越小。
可选地，在本公开实施例提供的显示面板中，对于第二显示子区域内的像素，根据该像素所在的位置在原始图像数据中对应的N个像素中的其中一个像素的灰阶值进行显示。显示原理遵守人眼视觉系统定量，不会出现闪烁， 无需重新设计集成电路(Integrated Circuit，IC)，成本低。
可选地，在本公开实施例提供的显示方法中，当第一显示子区域的像素分布密度与第二显示子区域的像素分布密度比值为n时，n为大于1的整数；
第二显示区域内各像素在原始图像数据中分别对应呈矩阵排列的n*n个像素。
在具体实施时，一般取n＝2，即当第一显示子区域的像素分布密度是第二显示子区域的像素分布密度的2倍。当然，根据实际应用，n也可以取其它值，在此不作限定。
具体地，以n＝2为例，如图10所示，第二显示区域内各像素在原始图像数据中分别对应呈矩阵排列的2行乘以2列个像素，图10中，一个虚线框内的4个像素为第二显示区域内一个像素对应的像素。
可选地，在本公开实施例提供的显示方法中，第二显示区域内各像素，分别选择其在原始图像数据中对应的n*n个像素中相同位置处的一个像素作为参考像素，第二显示区域内各像素分别根据其对应的参考像素的灰阶值进行显示。
同样以n＝2为例，如图11a所示，第二显示区域内各像素，分别可以选择其在原始图像数据中对应的2*2个像素中第一行第一列位置处的像素作为参考像素。或者，如图11b所示，第二显示区域内各像素，分别可以选择其在原始图像数据中对应的2*2个像素中第一行第二列位置处位置的像素作为参考像素。或者，如图11c所示，第二显示区域内各像素，分别可以选择其在原始图像数据中对应的2*2个像素中第二行第一列位置处位置的像素作为参考像素。如图11d所示，第二显示区域内各像素，分别可以选择其在原始图像数据中对应的2*2个像素中第二行第二列位置处位置的像素作为参考像素。
在具体实施时，在本公开实施例提供的显示方法中，第二显示区域内各像素分别根据其对应的参考像素的灰阶值进行显示，具体为：第一子像素根据对应的参考像素中第一子像素的灰阶值进行显示，第二子像素根据对应的参考像素中第二子像素的灰阶值进行显示，第三子像素根据对应的参考像素 中第三子像素的灰阶值进行显示。
在具体实施时，由于第一显示子区域的像素分布密度与第二显示子区域的像素分布密度的比值有可能不是整数，例如当第一显示子区域的像素分布密度与第二显示子区域的像素分布密度比值为m，其中m＝n+s，n为大于或等于1的整数，s为0至1之间的小数。第二显示区域内各像素在原始图像数据中分别对应呈矩阵排列的n*n个像素；或者，第二显示区域内各像素在原始图像数据中分别对应呈矩阵排列的n*(n+1)个像素；或者，第二显示区域内各像素在原始图像数据中分别对应呈矩阵排列的(n+1)*(n+1)个像素。具体实施原理与上述m＝n的情况相同，在此不作赘述。
本公开实施例提供的显示方法中，对于第一显示子区域内的像素，根据其在原始图像数据中对应的像素的灰阶值进行显示，具体实施可以参照相关技术，在此不作详述。
在具体实施时，在本公开实施例提供的显示方法中，根据原始图像数据获得各像素的灰阶值的算法可以集成在IC、外接的中央处理器(Central Processing Unit，CPU)或者微处理器中等，当然也可以是单独设置的驱动器，该驱动器与每个像素连接，在此不作限定。
在具体实施时，在本公开实施例提供的显示方法中，显示基板上的像素在根据其在原始图像数据中对应的像素进行显示时，为了优化显示效果，一般还需要经过SPR等图像处理模块的处理、Demura算法处理后才在显示屏上成像。
本公开实施例提供的显示基板、其显示方法、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、传感器、听筒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。并且在第二显示子区域内子像素分布均匀，可以保证第二显示子区域内亮度分布均匀。
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。
