具体实施方式
在诸如手机和平板电脑等智能电子设备上，由于需要集成诸如前置摄像头、光线感应器等感光器件，一般是通过在上述电子设备上设置透明显示区的方式，将感光器件设置在透明显示区下方，在保证感光器件正常工作的情况下来实现电子设备的全面屏显示。
但是由于显示面板的透明显示区与非透明显示区的像素密度不同，例如透明显示区的像素密度小于非透明显示区的像素密度，导致显示面板在显示时透明显示区与非透明显示区中邻接二者交界的区域显示的画面呈现锯齿感。并且，为了提高显示面板的美观性，一般将显示面板的边角处的边界设计为非直线型边界，邻接非直线型边界的区域中像素的排布方式呈阶梯状，也将导致在显示时该区域的显示画面也会呈现锯齿感。显示面板在显示时显示画面呈现的锯齿感会影响用户的使用体验。

第二显示区20中的像素单元可全部为第二像素单元32，也可包括第二像素单元32及其他面积不同于第二像素单元32的像素单元，第二显示区20中邻近交界30的像素单元可以是第二像素单元32，也可以是其他的像素单元。再次参见图3和图4，第二显示区20中的像素单元可包括面积相同的第二像素单元32及第四像素单元34。第四像素单元34可位于第二像素单元32与交界30之间。第二显示区20中邻近交界30的像素单元可以是第二像素单元32，也可以是第四像素单元34。图3中所示的区域a1为邻近交界30的第二像素单元32与交界30之间的区域，区域a1的面积小于第二像素单元32面积的三分之一；图4中所示的区域a2为邻近交界30的第四像素单元34与交界30之间的区域，区域a2的面积小于第二像素单元32的面积的三分之一。在其他实施例中，第二显示区20中的像素单元也可以包括两种以上不同面积的像素单元。例如，面积与第二像素单元32不同的像素单元，该像素单元邻近交界30设置。
第二显示区20中的第四像素单元34与第一显示区10中的第五像素单元35可以是相同的像素单元，则二者的面积相同。第四像素单元34与第五像素单元35也可以是不同面积的像素单元。
第二显示区20中邻接交界30的像素单元与交界30之间的区域指的是由该像素单元的相对的两边缘的延长线、交界30位于两个延长线之间的部分、以及该像素单元位于延长线之间且邻接交界30的边缘围合形成的区域。其中，像素单元包括多个亚像素时，像素单元相对的两边缘指的是不同亚像素的边缘中距离最远的相对两边缘且该距离最远的两边缘的延长线与交界30之间的区域无像素；像素单元包括一个亚像素时，像素单元相对的两个边缘为其包括的一个亚像素相对的两边缘且该两边缘的延长线与交界30之间的区域无像素。再次参见图4，像素单元34相对的两边缘的延长线分别为b1、b2，像素单元位于延长线之间的边缘b3、以及相交于交界30的延长线b1、b2、及交界30位于b1、b2之间的部分围合形成的区域为a2，区域a2的面积为第四像素单元34对应的第一面积。
第二显示区20中邻近交界30的像素单元与交界30之间的区域的面积越小，显示基板100显示时第二显示区20中邻近交界30的像素单元呈现的锯齿感越弱。邻近交界30 的像素单元对应的第一面积小于第二显示区20中的第二像素单元32的面积的三分之一时，该像素单元显示时呈现的锯齿感比较弱，用户不易分辨出锯齿感。当然，邻近交界30的像素单元对应的第一面积更小时，像素单元显示时呈现的锯齿感更弱。本申请实施例中也可以设置第二显示区20中邻近交界30的像素单元对应的第一面积小于第二像素单元32的四分之一、五分之一、六分之一等，以使第二显示区20中邻近交界30的像素单元呈现的锯齿感更弱。
参照图5，显示基板100的显示区(当显示面板包括第一显示区10和第二显示区20时，该显示区为第二显示区；或者显示面板包括一个正常显示区(非透明显示区))具有拟定边界40，且拟定边界40包括非直线型边界41时，显示基板100的该显示区中的像素单元可全部为第三像素单元33，也可以包括第三像素单元33及其他不同于第三像素单元33的像素单元，例如面积与第三像素单元不同的像素单元。显示区中邻近非直线型边界41的像素单元可以是第三像素单元33，也可以是其他的不同于第三像素单元33的像素单元。图5示出了图2中的区域B的像素排布。在图5中，显示基板100的显示区中的像素单元包括第三像素单元33及第六像素单元36，显示区中邻近非直线型边界41的像素单元可以是第三像素单元33，也可以是第六像素单元36。显示区中邻接非直线型边界41的像素单元与非直线型边界41之间的区域指的是，由该像素单元的相对的两边缘的延长线、非直线型边界41位于两个延长线之间的部分以及像素单元位于延长线之间且邻接非直线型边界41的两边缘围合形成的区域。图5中所示的第六像素单元36与非直线型边界41之间的区域为a4，区域a4的面积为第六像素单元36对应的第二面积，则区域a4的面积小于第三像素单元33面积的三分之一。在其他实施例中，显示基板100的显示区中的像素单元也可以包括两种以上的像素单元，例如，面积不同的两种以上的像素单元。
其中，显示区的拟定边界40不是实际存在的边界，拟定边界为显示基板100的显示区的理想边界。显示区内的像素单元的边界与拟定边界40基本重合时，显示基板100在显示时呈现的锯齿感很弱，用户的使用体验较好。为了提高显示基板100的美观性，通常将显示基板100的拟定边界的边界处设计为非直线型边界，例如圆弧形。由于邻近拟定边界40的非直线型边界41的像素单元的边界与非直线型边界41不可能完全重合，则邻近非直线型边界41的像素单元在显示时会呈现锯齿感。
再次参见图5，显示区内的像素单元也可部分超出非直线型边界41，在控制显示基板100显示时，可通过控制该部分超出非直线型边界41的像素单元的亮度小于位于非 直线型边界41内的像素单元的亮度来减弱锯齿感，但是显示基板100的边界超出拟定边界40，会影响显示基板100的美观。因此通常设置显示基板100的像素单元不超出显示基板100的拟定边界40，或者像素单元超出拟定边界的部分的面积特别小，以提升显示基板100的美观。
显示区中的像素单元未超出拟定边界40时，位于拟定边界40内且邻近非直线型边界41的像素单元与非直线型边界41之间的区域的第二面积越小，显示基板100显示时邻近非直线型边界41的像素单元呈现的锯齿感越弱。当邻近非直线型边界41的像素单元对应的第二面积小于显示区中的第三像素单元33的面积的三分之一时，该像素单元显示时呈现的锯齿感比较弱，用户不易观察到锯齿感，可提升用户的使用体验。当然，邻近非直线型边界41的像素单元对应的第二面积更小时，像素单元显示时呈现的锯齿感更弱。本申请实施例中也可以设置显示区中邻近非直线型边界41的像素单元对应的第二面积小于第三像素单元33的四分之一、五分之一、六分之一，从而使得显示区中邻近非直线型边界41的像素单元呈现的锯齿感更弱。
当显示基板100包括第一显示区10和第二显示区20，且显示基板100的显示区的拟定边界40包括非直线型边界41时，第三像素单元33与第二像素单元32可以是面积相同的像素单元，第四像素单元34、第五像素单元35及第六像素单元36也可以是面积相同的像素单元。如此，在制备掩膜板时，掩膜板的开口只包括两种尺寸规格的开口即可，可简化掩膜板的制备工艺。
在一个实施例中，再次参见图4，显示基板100包括第一显示区10和第二显示区20时，所述第二显示区20中的第四像素单元34的面积可等于第二像素单元32的面积，第四像素单元34位于至少部分第二像素单元32与交界30之间。或者，在其他实施例中，所述第二显示区20中的第四像素单元34的面积可小于第二像素单元32的面积。当第二像素单元32与交界30之间设置有第四像素单元34时，该第二像素单元32与交界30之间的第四像素单元34的数量可为一个，也可为多个。
优选的，第四像素单元34的面积小于第二像素单元32的面积。当邻近交界30的第二像素单元32与交界30之间的区域不足以设置一个第二像素单元32时，在该区域可设置面积小于第二像素单元32的第四像素单元34，从而进一步减小邻近交界30的第二像素单元32与交界30之间的区域的第一面积，进一步减弱第二显示区20显示时呈现的锯齿感。
进一步地，所述第二显示区20中邻近交界30的每一像素单元对应的第一面积均小 于所述第四像素单元34面积的三分之一。如此，可使得第二显示区20中邻近交界30的像素单元与交界30之间的区域的第一面积更小，进而使得第二显示区20显示时呈现的锯齿感更弱，更有利于提升用户的使用体验。
在一个实施例中，所述第一显示区10内的邻近所述交界30的每一像素单元与所述交界30之间的区域的第三面积可均小于所述第二像素单元32面积的三分之一。再次参见图4，第一显示区10中邻近交界30的第五像素单元35与交界30之间的区域为a3，则区域a3的面积为第五像素单元35对应的第三面积，区域a3的面积小于第二像素单元32面积的三分之一。如此设置，第一显示区10中邻近交界30的每一像素单元与交界30之间的区域的面积较小，可使得第一显示区10显示时呈现的锯齿感较弱，用户不易察觉第一显示区10邻接交界30的区域呈现的锯齿感。
进一步地，所述第一显示区10中的第五像素单元35的面积小于所述第一像素单元31的面积，且第五像素单元35设置在第一显示区10中邻近交界30的至少部分第一像素单元31与交界30之间。当第一像素单元31与交界30之间设置有第五像素单元35时，该第一像素单元31与交界30之间的第五像素单元35的数量可为一个，也可为多个。当邻近交界30的第一像素单元31与交界30之间的区域不足以设置一个第一像素单元31时，在该区域可设置面积小于第一像素单元31的第五像素单元35，从而可减小该第一像素单元31与交界30之间的区域的第三面积，进而可使得第一显示区10显示时呈现的锯齿感更弱。
更进一步地，所述第一显示区10中邻近交界30的每一像素单元对应的第三面积小于所述第五像素单元35面积的三分之一。如此设置，第一显示区10中邻近交界30的每一像素单元对应的第三面积更小，可使得第一显示区10显示时呈现的锯齿感更弱，用户更不易察觉第一显示区10邻接交界30的区域呈现的锯齿感。
所述显示基板100的显示区具有拟定边界40，且拟定边界40至少部分为非直线型边界41时，显示区中的第六像素单元36的面积可小于所述第三像素单元33的面积。第六像素单元36可位于至少部分第三像素单元33与非直线型边界41之间。当第三像素单元33与非直线型边界41之间设置有第六像素单元36时，该第三像素单元33与非直线型边界41之间的第六像素单元36的数量可为一个，也可为多个。邻近非直线型边界41的第三像素单元33与非直线型边界41之间的区域不足以设置一个第三像素单元33时，在该区域可设置面积小于第三像素单元33的第六像素单元36，从而进一步减小邻近非直线型边界41的第三像素单元33与非直线型边界41之间的区域的第二面积， 进而使显示基板100显示时邻接非直线型边界41的区域呈现的锯齿感更弱。
进一步地，所述显示基板100的显示区位于拟定边界40内的每一像素单元对应的第二面积均小于第六像素单元36面积的三分之一。如此设置，显示区中邻近非直线型边界41的每一像素单元对应的第二面积更小，可使得显示区显示时呈现的锯齿感更弱，用户更不易察觉显示区邻接非直线型边界41的区域呈现的锯齿感。
在一个实施例中，图4示出了第一显示区和第二显示区的位于对称轴D右侧的部分。所述显示基板100的显示区包括第一显示区10和第二显示区20时，所述第一显示区10与所述第二显示区20之间存在交界30时，所述第一显示区10可为轴对称图形，所述第一显示区10的像素单元沿所述第一显示区10的对称轴D对称分布，所述第二显示区20中邻近所述交界30的像素单元沿所述第一显示区10的对称轴D对称分布。如此设置，第一显示区10与第二显示区20的像素排布更规则，则蒸镀第一显示区10与第二显示区20中的像素时采用的掩膜板的开口排布比较规则，可使得制备掩膜板的工艺比较简单。其中，第一显示区10可呈水滴形、圆形、矩形、半圆形、半椭圆形或椭圆形等形状。但不限于此，也可根据实际情况将第一显示区10设计为其他形状。
在一个实施例中，所述第一显示区10可以是透明显示区，所述第一显示区10可至少部分被所述第二显示区20包围，所述第一显示区10下方可设置感光器件。如此设置，光线可透过第一显示区10进入到感光器件中，从而在保证摄像头和/或光线感应器正常工作的同时实现显示基板100的全面屏显示。
第一显示区10和第二显示区20的交界30为交界线。或者，第一显示区10与第二显示区20的交界30为交界区域，交界区域内可设置有用于驱动所述第一显示区10中像素的像素电路。将驱动第一显示区10中像素的像素电路设置在交界区域，可减少第一显示区10中的电路走线，降低第一显示区10中的结构复杂度，进而提高第一显示区10的透明度。当第一显示区10与第二显示区20的交界30为交界区域时，第一显示区10邻近交界30的像素单元指的是第一显示区10中邻近交界区域且靠近第一显示区10的边界的像素单元，第二显示区20邻近交界30的像素单元指的是第二显示区20中邻近交界区域且靠近第二显示区20的边界的像素单元。
所述第一显示区10的第一电极层可包括多个同向延伸的第一电极。每个第一电极可沿行方向延伸或者沿列方向延伸。图6至图11仅以第一电极的延伸方向为行方向为例进行示意，第一电极的延伸方向为列方向时的示意图不再列举。
参见图6和图7，第一显示区10的第一电极层包括多个同向延伸的第一电极21，每一所述第一电极21包括一个电极条，位于所述第一显示区10的发光层可包括对应设置在每一所述第一电极21上的多个间隔分布的发光结构块，或者位于所述第一显示区10的发光层包括对应设置每一所述第一电极21上的一个发光结构块，该发光结构块覆盖对应的第一电极21。所述第一显示区10中的一个像素包括位于同一个所述第一电极上的发光结构块。如此设置，可使得第一显示区10中的有机发光结构块的面积较大，从而使得第一显示区10的有效发光面积较大。
在另一个实施例中，参见图8至图10，第一显示区10的第一电极层包括多个同向延伸的第一电极21，每一第一电极21包括多个电极块211，位于所述第一显示区10的发光层包括对应设置在每个所述电极块211上的一个发光结构块，所述第一显示区10的一个亚像素包括设置在一个电极块211上的一个发光结构块。如此设置，第一显示区10中的第一电极的面积较小，可增大第一显示区10的透明度。同一个第一电极21的多个电极块211上对应设置的发光结构块的颜色可不相同，从而第一显示区10显示的画面更加丰富多彩。
每个所述第一电极21在所述衬底1上的正投影可包括一个图形单元或者由多个图形单元。其中，所述图形单元可为圆形、椭圆形、哑铃形、葫芦形或矩形。图6中所示的第一电极21包括一个电极条，该电极条在衬底上的正投影包括一个图形单元，该图形单元为矩形；图7中所示的第一电极21包括一个电极条，该电极条在衬底上的正投影包括多个图形单元，该图形单元为圆形；图8所示的第一电极21包括多个电极块211，每一电极块211在衬底上的正投影包括一个图形单元，该图形单元为矩形；图9所示的第一电极21包括多个电极块211，每一电极块211在衬底上的正投影包括一个图形单元，该图形单元为葫芦形；图10所示的第一电极21包括多个电极块211，每一电极块211在衬底上的正投影包括一个图形单元，该图形单元为哑铃形。当第一显示区10为透明显示区时，所述图形单元优选为圆形、椭圆形、哑铃形及葫芦形，如此第一电极21的宽度连续变化或者间断变化，相邻的两个第一电极21之间的间距连续变化或者间断变化，从而相邻的两个第一电极21产生衍射的位置不同，不同位置处的衍射效应相互抵消，可以有效减弱衍射效应，进而确保第一显示区10下方设置的摄像头拍照得到的图像具有较高的清晰度。
显示基板100的第一显示区10与第二显示区20可共用同一衬底。并且，第一显示区10中的发光结构与第二显示区20的发光结构可采用同一张掩膜板进行蒸镀，也即是 第一显示区10中的发光结构与第二显示区20的发光结构在同一工艺中形成，从而可简化显示基板100的制备工艺流程。
本申请实施例还提供一种显示基板的显示优化方法。参见图11，所述显示优化方法包括如下步骤110至步骤150。下面对各步骤进行介绍。
在步骤110中，提供显示基板的初始结构图，或读取显示基板的初始结构图。所述初始结构图中，所述显示基板的显示区包括第一显示区和第二显示区，所述第一显示区的像素单元包括多个第一像素单元，所述第二显示区的像素单元包括多个第二像素单元，所述第一显示区的像素密度小于所述第二显示区的像素密度，所述第一显示区与所述第二显示区之间存在交界，所述第一像素单元与所述第二像素单元分别包括n个像素，n≥1且n为整数；和/或，所述显示基板的显示区具有拟定边界，所述拟定边界至少部分为非直线型边界，所述显示区中的像素单元包括多个第三像素单元，所述第三像素单元包括n个像素，n≥1且n为整数。

本申请实施例提供的显示基板的显示优化方法，显示基板包括第一显示区与第二显示区时，通过计算第二显示区内邻近第一显示区与第二显示区的交界的每一像素单元与 所述交界之间的区域的第一面积，当像素单元对应的第一面积大于或等于第二像素单元的三分之一时，在该像素单元与所述交界之间的区域增加至少一个像素单元，可减小第二显示区的邻近交界的每一像素单元与交界之间的区域的第一面积，从而减弱邻近交界的每一像素单元呈现的锯齿感；显示基板具有拟定边界，拟定边界至少部分为非直线型边界时，通过计算拟定边界内邻近非直线型边界的每一像素单元与非直线型边界之间的区域的第二面积，在像素单元对应的第二面积大于或等于显示区的第三像素单元的三分之一时，在该像素单元与非直线型边界之间的区域增加至少一个像素单元，可减小拟定边界内的邻近非直线型边界的每一像素单元与非直线型边界之间的区域的第二面积，从而减弱邻近非直线型边界的每一像素单元呈现的锯齿感。因此，本申请实施例提供的显示基板的显示优化方法，可减弱显示基板显示的画面呈现的锯齿感，优化显示基板的显示效果。
在一个实施例中，所述显示基板的显示区包括第一显示区和第二显示区时，在所述第二显示区的像素单元与所述交界之间的区域增加的像素单元的面积小于或等于所述第二像素单元的面积。
当在所述第二显示区的像素单元与所述交界之间的区域增加的像素单元的面积等于第二像素单元的面积时，蒸镀采用的掩膜板中第二显示区的像素对应的开口的尺寸规格相同，可简化掩膜板的制备流程。
在所述第二显示区的像素单元与所述交界之间的区域增加的像素单元的面积小于所述第二像素单元的面积的情况下，当邻近交界的第二像素单元与交界之间的区域不足以设置一个第二像素单元时，在该区域可设置面积小于第二像素单元的面积的的像素单元，从而使得第二显示区的像素单元与交界之间的区域的第一面积减小，进而减弱第二显示区显示时呈现的锯齿感更弱。
本申请实施例中，在第二显示区中增加像素单元之后，增加的像素单元与交界之间的区域的面积可小于第二像素单元面积的三分之一。更进一步地，增加的像素单元与交界之间的区域的面积可小于增加的像素单元面积的三分之一。如此设置可使得第二显示区中像素单元与交界之间的区域的面积更小，更利于减弱第二显示区显示时呈现的锯齿感。
在一个实施例中，如图12所示，显示基板包括第一显示区与第二显示区时，显示基板的显示优化方法还可包括如下步骤160和步骤170。
在步骤160中，计算所述第一显示区内邻近所述交界的每一像素单元与所述交界之间的区域的第三面积。
在步骤170中，若所述第一显示区的像素单元对应的第三面积大于或等于所述第二像素单元的三分之一，在该像素单元与所述交界之间的区域增加至少一个像素单元。
上述步骤可减小第一显示区的邻近交界的每一像素单元与交界之间的区域的第三面积，从而减弱邻近交界的每一像素单元呈现的锯齿感，优化第一显示区的显示效果。
其中，步骤160与步骤120及步骤140可同时执行，也可不同时执行。步骤170在步骤160后执行。
进一步地，在所述第一显示区的像素单元与所述交界之间的区域增加的像素单元的面积小于或等于所述第一像素单元的面积。
当在所述第一显示区的像素单元与所述交界之间的区域增加的像素单元的面积等于所述第一像素单元的面积时，蒸镀采用的掩膜板中第一显示区的像素对应的开口的尺寸规格相同，可简化掩膜板的制备复杂度。
在所述第一显示区的像素单元与所述交界之间的区域增加的像素单元的面积小于所述第一像素单元的面积的情况下，当邻近交界的第一像素单元与交界之间的区域不足以设置一个第一像素单元时，在该区域可设置面积小于第一像素单元的像素单元，从而使得第一显示区的像素单元与交界之间的区域的第三面积减小，进而减弱第一显示区显示时呈现的锯齿感更弱。
本申请实施例中，在第一显示区中增加像素单元之后，增加的像素单元与交界之间的区域的面积可小于第一像素单元面积的三分之一。更进一步地，增加的像素单元与交界之间的区域的面积可小于增加的像素单元面积的三分之一。如此设置可使得第一显示区中邻近交界的像素单元与交界之间的区域的面积更小，更利于减弱第一显示区显示时呈现的锯齿感。
在一个实施例中，所述显示基板的显示区具有拟定边界，所述拟定边界至少部分为非直线型边界时，在所述显示区的位于所述拟定边界内的像素单元与所述非直线型边界之间增加的像素单元的面积可小于或等于所述第三像素单元的面积。
当在所述显示区的像素单元与所述非直线型边界之间的区域增加的像素单元的面积等于所述第三像素单元的面积时，蒸镀采用的掩膜板中显示区的像素对应的开口的尺寸规格相同，可简化掩膜板的制备复杂度。
优选的，在所述拟定边界内的像素单元与所述非直线型边界之间的区域中增加的像素单元的面积小于所述第三像素单元的面积。当邻近非直线型边界的第三像素单元与交界之间的区域不足以设置一个第三像素单元时，在该区域可设置面积小于第三像素单元的像素单元，从而使得显示区的像素单元与非直线型边界之间的区域的第三面积减小，更利于减弱显示区在显示时呈现的锯齿感。
其中，在所述拟定边界内的像素单元与所述非直线型边界之间的区域增加的像素单元可超出或不超出所述非直线型边界。
优选的，若增加的像素单元未超出非直线型边界时，在显示区中增加像素单元之后，增加的像素单元与交界之间的区域的面积可小于第三像素单元面积的三分之一。更进一步地，增加的像素单元与非直线型边界之间的区域的面积可小于增加的像素单元面积的三分之一。如此设置可使得显示区中的像素单元与非直线型边界之间的区域的面积更小，更利于减弱显示区在显示时呈现的锯齿感。
若增加的像素单元超出非直线型边界时，在控制显示基板显示时，可控制超出非直线型边界的像素单元的亮度小于位于拟定边界内的像素单元的亮度，从而达到减弱显示区呈现的锯齿感。
本申请实施例中，第一显示区和第二显示区的交界可以为交界线。或者，第一显示区与第二显示区的交界可以是交界区域，交界区域内可设置用于驱动所述第一显示区中像素的像素电路。当第一显示区与第二显示区的交界为交界区域时，第一显示区邻近交界的像素单元指的是第一显示区中邻近交界区域且靠近第一显示区的边界的像素单元，第二显示区邻近交界的像素单元指的是第二显示区中邻近交界区域且靠近第二显示区的边界的像素单元。
在一个实施例中，所述显示区包括第一显示区和第二显示区，且所述第二显示区具有拟定边界，所述拟定边界至少部分为非直线型边界时，所述第二像素单元与所述第三像素单元为同样的像素单元；在第一显示区增加的像素单元、在第二显示区增加的像素单元及在非直线型边界处增加的像素单元可以是相同的像素单元。如此设置，在制备掩膜板时，掩膜板的开口只包括两种尺寸规格的开口即可，可简化掩膜板的制备工艺。
上述实施例提供的显示基板的显示优化方法与上述的显示基板的实施例属于同一构思，相关细节详见显示基板的实施例部分，这里不再赘述。
本申请实施例还提供了一种显示面板。如图13所示，所述显示面板200包括上述的 显示基板100及封装层201，所述封装层201设置在所述显示基板100的背离其衬底的一侧。
其中，封装层201可以是薄膜封装结构，薄膜封装结构可包括有机材料层和无机材料层交替叠加的叠层，其中有机材料层和无机材料层均为透明材料，无机材料层的材料例如可以是SiO 2，SiNx以及Al 2O 3等，有机材料层的材料例如可以是PI、PET等。封装层201也可以是玻璃盖板或者是玻璃粉封装结构。
