具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置的例子。
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，因此相关技术中，通过在上述电子设备上设置透明显示屏的方式，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。
为了提高透明显示屏的透明度，一般设置透明显示屏的像素密度小于非透明显示屏的像素密度。但是发明人发现电子设备在显示时，有时会出现图像变形的情况，会影响用户的使用体验。
为解决上述问题，本申请实施例提供了一种显示基板、显示面板及显示装置，其能够很好的解决上述问题。
下面结合附图，对本申请实施例中的显示基板、显示面板及显示装置进行详细说明。在不冲突的情况下，下述的实施例及实施方式中的特征可以相互补充或相互组合。
本申请实施例提供了一种显示基板。参见图1和图2，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，第一显示区10的透光率大于第二显示区20的透光率。显示基板100还可包括衬底。参见图3、图4和和图7，所述第一显示区10内设置有多个第一像素单元11，所述第一像素单元11包括n种颜色的第一OLED(organic light-emitting diode)像素111、112、113，例如，第一OLED像素111、112、113分别对应一种不同的颜色。参见图11，所述第二显示区20内设置有多个第二像素单元21，所述第二像素单元21包括n种颜色的第二OLED像素211、212、213，例如，第二OLED像素211、212、213分别对应一种不同的颜色。其中，n为不小于3的自然数。第一OLED像素和第二OLED像素位于该衬底上。
再次参见图4和图7，所述第一OLED像素111包括沿第一方向间隔排布的至少两个第一子像素101。类似地，所述第一OLED像素112包括沿第一方向间隔排布的至少两个第一子像素103，以及所述第一OLED像素113包括沿第一方向间隔排布的至少两个第一子像素105。相邻且属于不同(例如，对应颜色不同)第一OLED像素的第一子像素101、103、105在第二方向上间隔排布，所述第一方向与所述第二方向相交。所述第一子像素101、103、105包括第一电极块、设置在所述第一电极块上的第一发光结构块及设置在所述第一发光结构块上的第二电极，同一(例如，对应同一种颜色)第一OLED像素111中相邻的两个第一子像素101的第一电极块电连接。类似地，同一第一OLED像素112中相邻的两个第一子像素103的第一电极块电连接，以及同一第一OLED像素113中相邻的两个第一子像素105的第一电极块电连接。
所述第一像素单元11的第一尺寸与第二尺寸的比值、及所述第二像素单元21的第一尺寸与第二尺寸的比值大致相同。所述第一尺寸为像素单元在所述第一方向上的尺寸，所述第二尺寸为像素单元在所述第二方向上的尺寸，第一方向与第二方向相交。也即是，第一像素单元11的第一尺寸为第一像素单元11在第一方向上的尺寸，第一像素单元11的第二尺寸为第一像素单元11在第二方向上的尺寸；第二像素单元21的第一尺寸为第二像素单元21在第一方向上的尺寸，第二像素单元21的第二尺寸为第二像素单元21在第二方向上的尺寸。
本申请实施例提供的显示基板，第一显示区10的透光率大于第二显示区20的透光率，则可将感光器件设置在第一显示区10下方，保证感光器件正常工作的前提下实现显示基板的全面屏显示。第一OLED像素包括至少两个第一子像素，且同一第一OLED像素中，相邻的两个第一子像素的第一电极块电连接，则同一第一OLED像素的第一子像素中的一个第一电极块连接信号线或者像素电路即可，可降低第一显示区10中走线的复杂度及结构的复杂度，进而可减弱外部光线通过第一显示区10时发生的衍射，降低外部光线的衍射对设置在第一显示区10下方的感光器件的影响。同时，第一像素单元11的第一尺寸与第二尺寸的比值、及第二像素单元21的第一尺寸与第二尺寸的比值大致相同，则第一像素单元与第二像素单元的形状比较接近，可降低由于第一像素单元与第二像素单元的形状差异较大导致的显示基板100显示时出现图像变形的概率，提升显示基板100的显示效果，进而提升用户的使用体验。
本申请实施例中，第一像素单元11的第一尺寸与第二尺寸的比值为第一比值、及第二像素单元21的第一尺寸与第二尺寸的比值为第二比值。第一比值与第二比值大致相同，包括两种情况：第一比值与第二比值相等，或者第一比值与第二比值的差值在指定的范围内。
其中，第一像素单元11的第一比值与第二像素单元21第二比值相同时，第一像素单元11的第一尺寸与第二像素单元21的第一尺寸可相同或不同。一般地，第一像素单元11的面积大于第二像素单元21的面积，也即是第一像素单元11的第一尺寸大于第二像素单元21的第一尺寸，第一像素单元的第二尺寸大于第二像素单元21的第二尺寸。
在本申请实施例中，同一第一OLED像素的至少两个第一子像素沿第一方向间隔排布，指的是同一第一OLED像素的至少两个第一子像素整体上大致沿第一方向排布。同一个第一OLED像素的至少两个第一子像素的沿第一方向的轴线可重合，也可不重合，例如如图4和图7中所示，同一个第一OLED像素的多个第一子像素在第一方向上错位，也认为该同一个第一OLED像素的多个第一子像素是沿第一方向间隔排布。
相邻且属于不同第一OLED像素的第一子像素在第二方向上间隔排布，可以包括两种情况：
第一种情况中，参见图7所示，同一第一像素单元11包括的n个第一OLED像素沿第二方向间隔排布，同一个第一OLED像素包括的第一子像素均位于另一个第一OLED像素(例如相邻的第一OLED像素)的同一侧。在该情况下，对于属于相邻的不同第一OLED像素，其第一子像素在第二方向上间隔排布。例如，图7中的第一OLED 像素112包括的第一子像素103均位于第一OLED像素113的同一侧。
第二种情况中，参见图4所示，同一第一像素单元11包括的n个第一OLED像素中，相邻两个第一OLED像素中，其中一个第一OLED像素的部分第一子像素位于另一个第一OLED像素(例如，相邻的第一OLED像素)的一侧，而另一部分第一子像素位于所述另一个第一OLED像素的另一侧。在该情况下，属于相邻的两个第一OLED像素的第一子像素在第二方向上间隔排布。例如，图4中的第一OLED像素112的部分第一子像素103位于第一OLED像素113的上侧，第一OLED像素112的另一部分第一子像素103位于第一OLED像素113的下侧，相邻的第一子像素103和第一子像素105在第二方向上间隔排布。
第一像素单元11在第一方向上的尺寸指的是第一像素单元11在第一方向上的最大尺寸，第一像素单元11在第二方向上的尺寸指的是第一像素单元11在第二方向上的最大尺寸。第二像素单元21在第一方向上的尺寸指的是第二像素单元21在第一方向上的最大尺寸，第二像素单元21在第二方向上的尺寸指的是第二像素单元21在第二方向上的最大尺寸。
在一个实施例中，第一方向与第二方向可互相垂直。第一方向可以是行方向，第二方向可以是列方向；或者，第一方向可以是列方向，第二方向可以是行方向。其中，图4至图10仅以第一方向为行方向、第二方向为列方向为例进行示意，其他情况不再进行示意。
在一个实施例中，第一像素单元11中第一子像素的排布规律与第二像素单元中的第二OLED像素的排布规律一致。其中，像素的排布规律指的是像素的排布方式，例如可以是同一颜色的相邻的像素的排布顺序、排布位置关系，不同颜色的像素的排布顺序、排布位置等。
像素的排布规律与像素所在的像素单元的尺寸没有必然的关系。例如，第一像素单元11中的第一子像素的排布规律、第二像素单元21中的第二OLED像素的排布规律相同，但是第一像素单元11的第一尺寸与第二像素单元21的第一尺寸、第一像素单元11的第二尺寸与第二像素单元21的第二尺寸可不等。
通过设置第一像素单元中的第一子像素的排布规律与第二像素单元中的第二OLED像素的排布方式相同，可使得显示基板100在显示时第一显示区10与第二显示区20的显示效果更一致，有利于提升用户的使用体验。
在一个实施例中，n＝3，也即是，第一像素单元11包括三种不同颜色的第一OLED像素，第二像素单元21包括三种不同颜色的第二OLED像素。其中，三种颜色可为红色、绿色和蓝色，也可以是其他的颜色。下面以三种颜色为红色、绿色和蓝色为例进行说明，三种颜色为其他颜色的情况不再进行介绍。当然，在其他实施例中，n的值也可大于3。
参见图4或图7，所述第一像素单元11包括红色的第一OLED像素111、绿色的第一OLED像素112和蓝色的第一OLED像素113，所述红色的第一OLED像素111包括至少两个红色的第一子像素101，所述绿色的第一OLED像素112包括至少两个绿色的第一子像素103，所述蓝色的第一OLED像素113包括至少两个蓝色的第一子像素105。参见图11，所述第二像素单元21可包括红色的第二OLED像素211、绿色的第二OLED像素212和蓝色的第二OLED像素213。进一步地，第二像素单元21中红色的第二OLED像素211、绿色的第二OLED像素212和蓝色的第二OLED像素213的数量分别为一个。
在一个实施例中，所述第一像素单元11中不同颜色的第一子像素可呈品字形排列，即，呈三角形排列；所述第二像素单元21中相邻且不同颜色的第二OLED像素可呈品字形排列，即呈三角形排列。参见图4，相邻设置的红色的第一子像素101、绿色的第一子像素103和蓝色的第一子像素105呈品字形排列。参加图11，相邻设置的红色的第二OLED像素211、绿色的第二OLED像素212和蓝色的第二OLED像素213呈品字形排列。
如此设置，第二像素单元21中相邻且对应三种颜色的第二OLED像素与第一像素单元11中相邻且对应三种颜色的第一子像素均呈三角形或品字形排列，可使得显示基板100在显示时第一显示区10与第二显示区20的显示效果更一致，有利于提升用户的使用体验。并且，同一颜色的第一子像素分布比较均匀，从而制备第一子像素的第一发光结构块的掩膜板上的开口排布比较规则，可减小掩膜板张网褶皱；同一颜色的第二OLED像素分布比较均匀，从而制备第二OLED像素的掩膜板上的开口排布比较规则，可减小掩膜板张网褶皱。
进一步地，所述第一像素单元11包括三个第一OLED像素，每一第一OLED像素包括四个沿第一方向间隔排布的第一子像素。由于第一像素单元11包括三个不同颜色的第一OLED像素，且第一像素单元11包括的第一OLED像素的数量为三个，则第一像素单元11中每种颜色的第一OLED像素的数量仅为一个，也即是，第一像素单元11包括一个红色的第一OLED像素111、一个绿色的第一OLED像素112和一个蓝色的第 一OLED像素113。其中，红色的第一OLED像素111包括四个沿第一方向间隔排布的红色的第一子像素101，绿色的第一OLED像素112包括四个沿第一方向间隔排布的绿色的第一子像素103，蓝色的第一OLED像素113包括四个沿第一方向间隔排布的蓝色的第一子像素105。
如此设置，第一像素单元11整体的形状大致呈矩形，形状比较规则，第一显示区10显示的图案不容易出现变形，可提高第一显示区10显示的图像的质量。并且，可使得第一像素单元11的形状与第二像素单元21的形状更接近，从而使第一显示区10与第二显示区20的显示效果更一致。同时，设置第一像素单元11包括三个第一OLED像素，每一第一OLED像素包括四个沿第一方向间隔排布的第一子像素，可在保证第一像素单元11整体的形状大致呈矩形的前提下，使得第一显示区10内的第一像素单元11的密度较高，有助于提升第一显示区10的显示效果。
在其他实施例中，第一像素单元11也可包括六个第一OLED像素，每一第一OLED像素包括六个沿第一方向间隔排布的第一子像素。也即是，第一像素单元11包括两个红色的第一OLED像素111、两个绿色的第一OLED像素112和两个蓝色的第一OLED像素113。其中，每一红色的第一OLED像素111包括六个沿第一方向间隔排布的红色的第一子像素101，每一绿色的第一OLED像素112包括六个沿第一方向间隔排布的绿色的第一子像素103，每一蓝色的第一OLED像素113包括六个沿第一方向间隔排布的蓝色的第一子像素105。如此设置，也可使第一像素单元11整体的形状大致呈矩形，形状比较规则。
进一步地，参见图5，所述第一像素单元11中的第一子像素可分为至少两个沿所述第二方向排布的第一像素组110，每一第一像素组110可沿第一方向延伸。相邻的两个第一像素组110中，其中一个第一像素组110中的第一子像素可按照第一顺序排列，另一第一像素组110中的第一子像素可按照第二顺序排列。其中，所述第一顺序可为红色的第一子像素101、绿色的第一子像素103、蓝色的第一子像素105，所述第二顺序可为蓝色的第一子像素105、绿色的第一子像素103、红色的第一子像素101。第一子像素按照第一顺序排列所呈的品字形可以是品字按照图5所示的方位向右倾斜90度所呈的形状，第一子像素按照第二顺序排列所呈的品字形可以是品字按照图5所示的方位向左倾斜90度所呈的形状。图5中所示的第一像素单元11中的第一子像素分为两个第一像素组110，其中一个第一像素组110中的第一子像素按照第一顺序排列，另一个第一像素组110中的第一子像素按照第二顺序排列。在其他实施例中，第一像素单元11中的第 一子像素也可分为三个或三个以上的第一像素组110。如此设置，可使得第一显示区10中在第一方向上相邻设置的第一子像素的颜色均不相同，同一颜色的第一子像素在第一显示区10中分布更均匀，有利于提高第一显示区10的显示效果。
进一步地，所述第一像素单元11的相邻两个第一像素组110的第一子像素中，在所述第二方向上间隔排布有三个第一子像素，且在所述第二方向上间隔排布的三个第一子像素的颜色不同。如图5中所示，相邻的两个第一像素组110中，在所述第二方向上间隔排布的三个第一子像素分别为红色的第一像素101、绿色的第一子像素103和蓝色的第一子像素105。如此设置，可使得第一显示区10中在第二方向上相邻设置的第一子像素的颜色均不相同，同一颜色的第一子像素分布更均匀，可避免第一显示区10的某一区域内多个同一颜色的第一子像素相邻而导致第一显示区10显示时出现颜色分布不均匀，进而导致该区域出现单一颜色的亮条的问题，可提高第一显示区10的显示效果。
在一个实施例中，如图11所示，所述第二显示区20可包括多个沿所述第二方向排布的第二像素组210，每一第二像素组210可沿第一方向延伸。其中，每一第二像素组210可包括第二像素单元21。相邻的两个第二像素组210中，其中一个第二像素组210中的第二OLED像素按照第三顺序排列，另一第二像素组210中的第二OLED像素按照第四顺序排列，所述第三顺序为红色的第二OLED像素211、绿色的第二OLED像素212、蓝色的第二OLED像素213，所述第四顺序为蓝色的第二OLED像素213、绿色的第二OLED像素212、红色的第二OLED像素211。其中，第二OLED像素按照第三顺序排列所呈的品字形可以是品字按照图11所示方位向右倾斜90度所呈的形状，第二OLED像素按照第四顺序排列所呈的品字形可以是品字按照图11所示方位向左倾斜90度所呈的形状。如此设置，可使得第二显示区20中在第一方向上相邻设置的第二OLED像素的颜色均不相同，同一颜色的第二OLED像素在第二显示区20中分布更均匀，有利于提高第二显示区20的显示效果。
进一步地，所述第二像素单元21的两个相邻的第二像素组210中，在所述第二方向上间隔排布有三个第二OLED像素，且如图11所示，相邻的两个第二像素组210中，在所述第二方向上间隔排布的三个第二OLED像素分别为红色的第二OLED像素211、绿色的第二OLED像素212和蓝色的第二OLED像素213。如此设置，可使得第二显示区20中在第二方向上相邻设置的第二OLED像素的颜色均不相同，从而同一颜色的第二OLED像素分布更均匀，可避免第二显示区20的某一区域内多个同一颜色的第二OLED像素相邻而导致第二显示区20显示时出现颜色分布不均匀，进而导致该区域出 现单一颜色的亮条的问题，可提高第二显示区20的显示效果。
在另一个实施例中，同一所述第一像素单元11中的多个第一OLED像素可在第二方向上并列排布，第二像素单元21中的第二OLED像素在第二方向上并列排布。参见图12，第一像素单元11中，红色的第一OLED像素111、绿色的第一OLED像素112和蓝色的第一OLED像素113在第二方向上间隔且并列排布，从而第一像素单元11中，红色的第一子像素101、绿色的第一子像素103和蓝色的第一子像素105在第二方向上间隔且并列排布，例如在第二方向上对齐排布。参见图13，第二像素单元中，红色的第二OLED像素211、绿色的第二OLED像素212和蓝色的第二OLED像素213在第二方向上间隔且并列排布。如此设置，第一像素单元中的第一子像素的排布规律与第二像素单元中第二OLED像素的排布规律一致。
进一步地，所述第一像素单元的在所述第二方向上排布的多个第一子像素中，相邻三个第一子像素的颜色各不相同；所述第二像素单元中在所述第二方向上排布的第二OLED像素中，相邻三个第二OLED像素的颜色各不相同。参见图12，所述第一像素单元的在所述第二方向上排布的多个第一子像素中，相邻三个第一子像素分别为红色的第一子像素101、绿色的第一子像素103和蓝色的第一子像素105。参见图13，所述第二像素单元中在所述第二方向上排布的第二OLED像素中，相邻三个第二OLED像素分别为红色的第二OLED像素211、绿色的第二OLED像素212和蓝色的第二OLED像素213。如此设置，可使得第一像素单元中的第一子像素、第二像素单元中的第二OLED像素的排布规律更相似，有助于提升第一显示区10与第二显示区20的显示效果的一致性。
进一步地，如图12所示，第一像素单元11还可包括连接条，该连接条连接相同颜色的第一OLED像素的第一电极块。而且，同一第一OLED像素包括连接相邻两个第一子像素的第一电极块的连接部。第一OLED像素的连接条可与第一OLED像素的第一电极块设置在同一层，或者与第一OLED像素的第一电极块设置在不同层。无论连接条设置在哪一层，均需保证设置在同一层的连接条与连接部不相交。
当然，在其他实施例中，第一像素单元中第一OLED像素的第一子像素的排布方式可不同于图4、图7或图12，第二像素单元中第二OLED像素的排布方式也可不同于图11和图13的排布方式，只要能保证第一像素单元中第一子像素的排布规律与第二像素单元中第二OLED像素的排布规律一致即可。
在一个实施例中，参见图4或图7，同一所述第一OLED像素的至少两个第一子像 素中，相邻的两个第一子像素在所述第二方向上可错位排布。也即是第一OLED像素的第一电极块中，相邻的两个第一电极块在第二方向上错位排布，如此设置可进一步减弱外部入射的光线通过显示基板100的第一显示区10时产生的衍射效应。
在一个实施例中，参见图4或图7，同一所述第一OLED像素的至少两个第一子像素中，间隔一个第一子像素设置的两个第一子像素在所述第一方向上的中轴线可重合。如此设置同一第一OLED像素的第一发光结构块的排布更规则，进而制备发光结构块采用的掩模板的开口排布比较规则。并且，在蒸镀包括第一显示区和第二显示区的显示基板的发光结构块时，可采用同一掩膜板在同一蒸镀工艺中制作，由于掩膜板上的图形较均匀，也减少了张网褶皱。
在一个实施例中，参见图4和图7，同一第一像素单元还可包括多个连接部，例如第一OLED像素111可包括至少一个连接部102，第一OLED像素112可包括至少一个连接部104，第一OLED像素113可包括至少一个连接部106。同一第一OLED像素中，相邻的两个第一电极块1011通过对应的连接部电连接。其中，红色的第一OLED像素111中相邻的第一电极块通过连接部102电连接，绿色的第一OLED像素112中相邻的第一电极块通过连接部104电连接，蓝色的第一OLED像素113中相邻的第一电极块通过连接部106电连接。
在一个实施例中，所述显示基板100还包括衬底，所述第一OLED像素和所述第二OLED像素位于所述衬底上。所述第一像素单元11中不同颜色的第一子像素呈品字形排列时，不同第一OLED像素的连接部在衬底上的投影存在相交的情况。如图6中所示，连接部102及连接部104在衬底上的投影分别与连接部106在衬底上的投影相交。同一第一像素单元中的连接部102、104、106的数量为多个时，至少部分连接部分别与相应的所述第一电极块1011设置在不同层。如此，可避免不同的连接部交叉设置而短路，进而影响第一OLED像素的正常工作，并且连接部的走线方式更灵活。并且，第一电极块1011的尺寸不受到与第一电极块1011不同层设置的连接部影响。
在另一个实施例中，如图8中所示，第一像素单元11中不同颜色的第一OLED像素在第二方向上间隔排布时，不同第一OLED像素的连接部在衬底上的投影不存在相交的情况，如图7中的连接部102、连接部104和连接部106在衬底上的投影均不相交。在该情况下，各个第一OLED像素的连接部可设置在同一层，也可设置在不同层。连接部可与对应的第一电极块1011设置在同一层，也可设置在不同层。优选的，第一像素单元11的连接部可分别与相应的第一电极块1011设置在同一层，则第一像素单元11 的第一电极块1011与连接部102、104、106可在同一工艺步骤中形成，可在一定程度上降低制备工艺的复杂度。
在一个实施例中，所述连接部与相应的所述第一电极块1011设置在不同层时，该连接部可分别设置在对应的所述第一电极块1011下方。如此设置，连接部不会影响第一OLED像素的显示。
进一步地，所述第一OLED像素的驱动方式为主动驱动时，显示基板100还包括用于驱动第一OLED像素的像素电路。所述第一OLED像素对应的像素电路可为1T电路、或2T1C电路、或3T1C电路、或3T2C电路、或7T1C电路、或7T2C电路。其中T代表晶体管，C代表电容。同一第一OLED像素的连接部与对应的第一电极块1011位于不同层时，第一OLED像素的连接部可与晶体管的栅电极设置在同一层，或者与电容的上极板设置在同一层，或者与晶体管的源电极设置在同一层。
在一个实施例中，所述显示基板100还包括衬底，所述第一OLED像素和所述第二OLED像素位于所述衬底上，同一第一像素单元11中的连接部的数量为多个时，同一第一像素单元中，在所述衬底上的投影相交的连接部可设置在不同层，在所述衬底上的投影不相交的连接部可设置在同一层或者不同层。如此设置，可避免在衬底上的投影相交的连接部设置在同一层时影响第一OLED像素的正常工作。其中，在衬底上的投影不相交的连接部设置在同一层时，这些连接部可在同一工艺步骤中形成，从而可降低制备工艺的复杂度。
在一个实施例中，同一第一OLED像素的连接部的数量为多个时，该第一OLED像素的连接部可设置在同一层。如此设置，同一第一OLED像素的多个连接部可在同一工艺步骤中形成，可简化工作的复杂度。例如，红色的第一OLED像素111包括的多个连接部102设置在同一层，绿色的第一OLED像素112包括的多个连接部104设置在同一层，蓝色的第一OLED像素113包括的多个连接部106设置在同一层。
在一个实施例中，所述第一像素单元11中不同颜色的第一子像素呈品字形排列时，参见图4，所述红色的第一OLED像素111包括的连接部102及所述绿色的第一OLED像素112包括的连接部104在衬底上的投影不相交，则可设置在同一层。所述蓝色的第一OLED像素113包括的连接部106与红色的第一OLED像素111包括的连接部102、以及与绿色的第一OLED像素112包括的连接部104在衬底上的投影均相交，则蓝色的第一OLED像素113包括的连接部106与红色的第一OLED像素111包括的连接部102及绿色的第一OLED像素112包括的连接部104设置在不同层。其中，红色的第一OLED 像素111包括的连接部102及绿色的第一OLED像素112包括的连接部104可分别与对应的第一电极块1011设置在同一层，蓝色的第一OLED像素113包括的连接部106与对应的第一电极块1011设置在不同层。当然，在其他实施例中，也可以是红色的第一OLED像素111包括的连接部102及绿色的第一OLED像素112包括的连接部104分别与对应的第一电极块1011设置在不同层，而蓝色的第一OLED像素113包括的连接部106与对应的第一电极块1011设置在同一层；或者，蓝色的第一OLED像素113包括的连接部106与红色的第一OLED像素111包括的连接部102及绿色的第一OLED像素112包括的连接部104设置在不同层，且三种颜色的第一OLED像素包括的连接部均与对应的第一电极块1011设置在不同层。
在一个实施例中，同一第一OLED像素包括的连接部与对应的第一电极块1011设置在同一层时，该连接部在垂直于其延伸方向上的尺寸大于3μm，且小于所述第一电极块1011的最大尺寸的二分之一。例如，连接部在垂直于其延伸方向上的尺寸为在沿第一方向和第二方向延伸的平面上的尺寸。通过设置连接部在垂直于其延伸方向的尺寸大于3μm，可使得连接部的电阻较小；通过设置连接部的尺寸小于第一电极块1011的最大尺寸的二分之一，可使得连接部的设置对第一电极块1011的尺寸影响较小，避免连接部的尺寸较大导致第一电极块1011的尺寸减小，进而导致第一显示区10的有效发光面积减小。
在一个实施例中，所述第一像素单元11包括两个以上颜色相同的第一OLED像素时，该两个以上的颜色相同的第一OLED像素中，不同第一OLED像素的第一电极块电连接，或一个第一OLED像素的第一电极块电连接另一个第一OLED像素的第一电极块。进一步地，第一像素单元内还可设置有连接条，相同颜色的第一OLED像素中，不同第一OLED像素的第一电极块可通过连接条电连接，或一个第一OLED像素的第一电极块可通过连接条电连接至另一个第一OLED像素的第一电极块。
参见图12，第一像素单元11包括两个红色的第一OLED像素111、两个绿色的第一OLED像素112和两个蓝色的第一OLED像素113。其中，两个红色的第一OLED像素111的第一电极块通过连接条107电连接，两个绿色的第一OLED像素112的第一电极块通过连接条108电连接，两个蓝色的第一OLED像素113的第一电极块通过连接部109电连接。
连接条将两个颜色相同的第一OLED像素的第一电极块电连接，可通过以下两种方式实现：其中一个第一OLED像素的一个连接部与另一个第一OLED像素的一个连接 部通过连接条连接在一起；或者，其中一个第一OLED像素的一个第一电极块与另外一个第一OLED像素的一个第一电极块通过连接条连接在一起。
如此设置，当第一OLED像素为主动驱动时，两个相同颜色的第一OLED像素可由同一个像素电路驱动，可减少像素电路的数量，从而可减小显示基板的结构的复杂度。
在一个实施例中，所述第一电极块1011在所述衬底上的投影可包括一个第一图形单元或者多个相连的第一图形单元。其中，所述第一图形单元包括圆形、椭圆形、哑铃形、葫芦形或矩形。其中，哑铃形指的是两个圆、与在两个圆之间的、间距小于所述两个圆直径的两条平行直线连接形成的图案的形状，葫芦形指的是两个圆直接连接形成的图案的形状。图6和图8中所示的第一图形单元为矩形，图9中所示的第一图形单元为圆形，图10中所示的第一图形单元为哑铃形。所述第一图形单元为圆形、椭圆形、哑铃形及葫芦形时，上述形状可改变衍射产生的周期性结构，即改变了衍射场的分布，从而减弱外部入射光通过第一显示区10时产生的衍射效应，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。
