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，通常在电子设备上设置透明显示区，并将感光器件设置在透明显示区下方。
为了提高透明显示区的透明度及降低透明显示区的结构复杂度，透明显示区内像素对应的像素电路通常设置在非透明显示区，透明显示区像素通过走线与对应的像素电路连接。透明显示区内各像素与对应的像素电路之间的走线均位于同一层。然而，为了保证像素正常工作，各走线之间不能交叉，且由于走线与像素一一对应，因此，走线的数量相对较少，使得透明显示区内像素的数量较少，即透明性显示区的像素密度较小，从而影响透明显示区的显示效果。
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。
下面结合附图，对本申请实施例中的显示基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。如图1所示，显示基板100包括第一显示区110及第二显示区120。第一显示区110的透光率大于第二显示区120的透光率，可以在有效保证感光器件正常工作的前提下，实现显示基板100的全面屏显示。
如图2所示，所述第一显示区110内设有多个像素单元10，所述像素单元10包括至少三种不同发光颜色的子像素组11、12、13。所述子像素组包括至少一个子像素111、121、131，每个子像素111、121、131包括第一电极、位于第一电极上的发光结构及位于所述发光结构上的第二电极。同一子像素组中的子像素的发光颜色相同。子像素组11、12、13包括两个或两个以上子像素111、121、131时，该子像素组中各子像素的第一电极依次电连接。也即是，该子像素组中相邻两个子像素的第一电极电连接。用于驱动所述子像素组11、12、13的像素电路21设置在所述第二显示区120。在一实施例中，第二显示区120内设置有与子像素组一一对应的多个像素电路21。第一显示区110内的子像素组11、12、13对应的像素电路设置在第二显示区120内，可有效提高第一显示区110的透光率，并可降低第一显示区110的结构复杂度，进而可减弱外部光线通过第一显示区110时产生的衍射效应，从而提高第一显示区110下方设置的摄像头的成像质量。
所述第一显示区110内的多个子像素组11、12、13中，至少存在一个子像素组11、12、13的一个第一电极通过第一连接部与对应的像素电路21电连接，以及至少存在另一子像素组11、12、13的第一电极通过第二连接部与对应的像素电路21电连接。所述第一连接部与所述第二连接部位于不同层，如此可以设置较多数量的第一连接部与第二连接部；所述第二连接部与所述子像素组的第一电极位于不同层，且由于第一连接部及第二连接部的总数与子像素组的数量相同，则可设置更多的子像素组，可以有效提高第一显示区110的像素密度，从而提升第一显示区110的显示效果。
在一实施例中，子像素组包括一个第一电极，该第一电极与该子像素组对应的像素电路连接。在一实施例中，子像素组包括两个或两个以上第一电极，其中一个第一电极与该子像素组对应的像素电路连接。其中，像素电路驱动子像素组，指的是像素电路同时驱动该子像素组中的各子像素。
在一个实施例中，第一电极可为阳极，第二电极可为阴极，第一显示区110中多个子像素组的阴极可为连成一片的面电极。
在一个实施例中，如图2和图3所示，所述第一显示区110包括第一侧141及与所述第一侧141相对的第二侧142，从所述第一侧141至所述第二侧142的方向为第一方向。
第一显示区110内的多个像素单元10形成多个像素单元组101，每一像素单元组101包括沿所述第一方向间隔排布的多个像素单元10。所述像素单元组101的多个像素单元10中，靠近所述第一侧141的至少一个像素单元10为目标像素单元102。同一像素单元组101的多个像素单元10中，靠近所述第一侧141的目标像素单元102与所述第一侧141之间的距离小于其他像素单元10与所述第一侧141之间的距离。和/或，所述像素单元组101的多个像素单元10中，靠近所述第二侧142的至少一个像素单元10为目标像素单元102。同一所述像素单元组101的多个像素单元10中，靠近所述第二侧142的目标像素单元102与所述第二侧142之间的距离小于其他像素单元10与所述第 二侧142之间的距离。
在一实施例中，如图3所示，每个像素单元组101包括六个像素单元10，其中靠近第一显示区110的第一侧141的目标像素单元102的数量为两个，靠近第一显示区110的第二侧142的目标像素单元102的数量为两个。在其他实施例中，每一像素单元组中像素单元10的数量可不同于六个。
在一实施例中，如图4至图7所示，子像素组大致沿第一方向排布，子像素组包括两个或两个以上子像素时，同一子像素组中两个或两个以上子像素沿第一方向间隔排布。同一子像素组中两个或两个以上子像素沿第一方向间隔排布，指的是两个或两个以上子像素在第一方向上的中轴线间隔距离N，N大于等于0。
在一实施例中，所述目标像素单元102中的至少一个子像素组11、12、13的一个第一电极1111、1211、1311通过第一连接部103与对应的像素电路21电连接。所述第一显示区110中其他所述子像素组11、12、13的一个第一电极1111、1211、1311可均通过第二连接部与对应的像素电路21电连接。在一实施例中，如图5和图7中所示，子像素111包括第一电极1111，子像素121包括第一电极1211，子像素131包括第一电极1311。各目标像素单元102中的至少一个子像素组的一个第一电极通过第一连接部103电连接，可使得第一连接部103设置的数量较大，在第二连接部的数量一定时，第一显示区110中第一连接部103与第二连接部的设置总数量较大，如此可在第一显示区110中设置更多的子像素组，有效提高第一显示区110的像素密度。
在一个实施例中，如图4和图6所示，所述第一显示区110中，所述目标像素单元102中各子像素组11、12、13的一个第一电极1111、1211、1311均通过所述第一连接部103与对应的像素电路21电连接。如此设置，可使得第一连接部103的数量较多，第一显示区110中第二连接部可设计的数量一定时，可使得第一连接部103与第二连接部的总数增加，进而使得第一显示区110中子像素组11、12、13的数量增大，有助于提升第一显示区110内子像素组的密度。
在一个实施例中，所述第一显示区110的各像素单元组101中，靠近所述第一显示区110的第一侧141的一个或两个所述像素单元10为所述目标像素单元102，和/或，靠近所述第一显示区110的第二侧142的一个或两个所述像素单元10为所述目标像素单元102。第一显示区110内除目标像素单元102之外的像素单元为第二类像素单元，第二类像素单元中的子像素组的一个第一电极可通过第二连接部与对应的像素电路连接。在一实施例中，如图4和图6所示，靠近第一显示区110的第一侧141的两个像素单元10均为目标像素单元102，靠近第一显示区110的第二侧142的两个像素单元10均为目标像素单元102。如此设置，一方面可使得第一连接部103的设置数量较多，第一连接部103与第二连接部的设置总数量增加，从而可使得第一显示区110中子像素组11、12、13的数量较多，能够有效提升第一显示区110内子像素组的密度。另一方面，可有效避免靠近第一侧141或者靠近第二侧142的目标像素单元的数量过多，而导致的有些目标像素单元中的子像素组的第一电极与对应的像素电路之间的距离过远，第一连接部的长度较长，从而有效避免第一连接部的走线方式对第一电极的设置的影响。
在一实施例中，第一显示区110的各像素单元组101中，靠近所述第一显示区110的第一侧141的一个或两个所述像素单元10为所述目标像素单元102，且靠近所述第一显示区110的第二侧142的一个或两个所述像素单元10为所述目标像素单元102，同时目标像素单元102内各子像素组的一个第一电极均通过第一连接部103电连接。如此可在不影响第一电极的尺寸及数量的前提下，使第一连接部103的数量较大。

子像素组的两个或两个以上子像素中，距离第二显示区120最近的子像素的第一电极与对应的所述像素电路电连接。如此设置，可减小第一电极与像素电路之间的连接部的长度，能够有效提高第一显示区的透明度，降低外部光线通过第一显示区时产生的衍射强度。如图5和图7所示，两个目标像素单元102中，子像素组11的四个第一电极1111中，与第二显示区120距离最近的第一电 极1111与对应的像素电路21电连接；子像素组12的四个第一电极1211中，距离第二显示区120最近的第一电极1211与对应的像素电路21电连接；子像素组13的四个第一电极1311中距离第二显示区120最近的第一电极1311与对应的像素电路21电连接。第一显示区中除目标像素单元外的其他像素单元的多个子像素组中，每一子像素组的距离第二显示区120最近的子像素的第一电极，通过第二连接部与对应的像素电路连接。

在一实施例中，所述子像素单元15包括第一区域151、第二区域152和第三区域153，所述第一区域151与第二区域152在第二方向上排列，所述第三区域153与所述第一区域151在所述第一方向上排列，所述第一区域151与所述第二区域152之间的在第一方向上的第一中轴线与所述第三区域153第一方向上的第二中轴线基本重合。其中，第一中轴线与第二中轴线基本重合指的是第一中轴线与第二中轴线完全重合，或者在第二方向上的距离在阈值范围内；在一实施例中，阈值为40微米。所述第一颜色的子像素111位于所述第一区域151，所述第二颜色的子像素121位于所述第二区域152，所述第三颜色的子像素131位于所述第三区域153。在所述第二方向上相邻的两个子像素单元15中，其中一个子像素单元15的所述第三区域153位于所述第一区域151的第三侧，另一个子像素单元15的所述第三区域153位于所述第一区域151的第四侧，所述第三侧与所述第四侧相对。在所述第一方向上间隔排布的多个子像素单元15的第三区域153位于第一区域151的同一侧。
如此设置，在第一方向或者第二方向上，第一颜色的子像素111、第二颜色的子像素121及第三颜色的子像素131在第一显示区110内均匀分布，可避免第一显示区的某一区域内多个相同颜色的子像素相邻而使得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亮条的问题，可有效改善显示效果。并且，相同颜色的子像素111、121、131分布比较均匀，从而制备子像素的发光结构采用的掩膜板开口排布比较规则，可减小掩膜板张网褶皱。
在一个实施例中，像素单元包括三种发光颜色不同的子像素组。三种发光颜色可分别为红色、绿色和蓝色。第一颜色、第二颜色及第三颜色分别为不同的上述三种颜色。例如，第一颜色为红色，第二颜色为绿色，第三颜色为蓝色；或者，第一颜色为红色，第二颜色为蓝色，第三颜色为绿色。在其他实施例中，像素单元包括三种发光颜色的子像素组时，三种颜色可以是其他颜色。在一些实施例中，像素单元可包括三种以上发光颜色的子像素组。
在一实施例中，如图4和图5，所述像素单元组101包括靠近所述第一侧141的两个目标像素单元102，和/或，包括靠近所述第二侧142的两个目标像素单元102。其中靠近第一侧141或第二侧142的两个目标像素单元102中，邻近所述第二显示区120的目标像素单元102为第一像素单元105，另一目标像素单元为第二像素单元106。
在一实施例中，各像素单元10中子像素单元15内的子像素呈品字形排列，所述第二像素单元106中第一颜色的子像素组11对应的第一连接部103，位于所述第一像素单元105中第一颜色的子像素组11背离所述第一像素单元105中第二颜色的子像素组12一侧。所述第二像素单元106中第二颜色的子像素组12对应的第一连接部103，位于所述第一像素单元105中第二颜色的子像素组12与所述第一像素单元105中第一颜色的子像素组11之间。所述第二像素单元106中第三颜色的子像素组13对应的第一连接部103，位于所述第一像素单元105中第二颜色的子像素组12的背离所述第一像素单元105中第一颜色的子像素组11的一侧。
如此设置，第二像素单元106中各子像素组对应的连接部103位置设计相对合理，对子像素组的尺寸影响较小。
在一实施例中，显示基板100可包括衬底，第一显示区110中各子像素组位于衬底上方。图4所示的像素排布方式中，走线132在衬底上的投影分别与走线112及走线122在衬底上的投影相交，走线112与走线122在衬底上的投影不相交，因而，可将走线112与走线122设置在同一层，将走线132与走线112设置在不同层，在一实施例中，走线112与走线122可与子像素组的第一电极设 置在同一层。走线132可设置在第一电极下方。
在另一个实施例中，像素单元10中子像素组的排布可如图6所示，像素单元10包括一个第一颜色的子像素组11、一个第二颜色的子像素组12和一个第三颜色的子像素组13。三个子像素组在第二方向上间隔排布，第二颜色的子像素组12位于第一颜色的子像素组11与第三颜色的子像素组13之间。第二像素单元106中第一颜色的子像素组11对应的第一连接部103，位于第一像素单元105中第一颜色的子像素组11背离第一像素单元105中第二颜色的子像素组12一侧。第二像素单元106中第二颜色的子像素组12对应的第一连接部103，位于第一像素单元105中第一颜色的子像素组11与第一像素单元105中第二颜色的子像素组12之间。第二像素单元106中第三颜色的子像素组13对应的第一连接部103，位于第一像素单元105中第三颜色的子像素组13与第一像素单元105中第二颜色的子像素组12之间。第二像素单元106中各子像素组对应的第一连接部103的走向，与第一像素单元105中子像素组的各第一电极之间的走线112、122、132的走向大致相同。
图6和图7所示的像素排布方式中，走线132在衬底上的投影、走线112在衬底上的投影及走线122在衬底上的投影均不相交，则可将走线112、走线122及走线132设置在同一层，在一实施例中，走线112、走线122及走线132可与子像素组的第一电极设置在同一层。
在一个实施例中，如图8和图9所示，用于驱动子像素组的像素电路包括晶体管22，晶体管22包括源极221、漏极222、栅极223和半导体层224。其中，晶体管22的漏极222与子像素组的一个第一电极1111电连接。在一实施例中，第一电极通过第一连接部103或第二连接部104与晶体管22的漏极222电连接。在一实施例中，如图8及图9所示，子像素组11的一个第一电极1111通过第一连接部103及第二连接部104与对应的像素电路连接，子像素组12的一个第一电极1211、及子像素组13的一个第一电极1311通过第一连接部103及第二连接部104与对应的像素电路连接的结构示意图与图8及图9相似。
在一实施例中，如图8所示，所述第一连接部103与所述子像素组的一个第一电极位于同一层。如此设置，第一连接部103与子像素组的一个第一电极的材料相同时，第一连接部103与子像素组的第一电极可在同一工艺步骤中形成，有助于简化显示基板100的制备工艺。第一连接部103与子像素组的第一电极的材料相同时，第一连接部103与第一电极可均为夹层结构，该夹层结构包括两层氧化铟锡及位于两层氧化铟锡之间的银。在一实施例中，第一连接部103与子像素组的第一电极的材料可不同，例如第一电极包括两层氧化铟锡及位于两层氧化铟锡之间的银，第一连接部103的材料可为氧化铟锡或者氧化铟锌等。
在一实施例中，如图9所示，所述第二连接部104位于第一电极下方，且所述第二连接部104与所述第一电极之间设有绝缘层30，所述绝缘层30上设有接触孔(未图示)，所述第二连接部104通过所述接触孔与所述第一电极电连接。第二连接部104设置在第一电极下方，则第二连接部104的设置不会影响第一电极的尺寸，从而可设置较大尺寸的第一电极，进而可有效增大第一显示区110的有效显示面积。在一实施例中，绝缘层30可为平坦化层。
在一个实施例中，所述第一连接部103、所述第二连接部104和/或所述第一电极的材料包括氧化铟锡、或者氧化铟锌、或者掺杂银的氧化铟锡或者掺杂银的氧化铟锌。在一实施例中，第一连接部103、第二连接部104和/或第一电极的材料可采用掺杂银的氧化铟锡或者掺杂银的氧化铟锌，以在保证第一显示区110的高透光率的基础上，能够有效减小第一连接部103、第二连接部104和/或第一电极的电阻。
在一个实施例中，显示基板100包括衬底，第一电极位于衬底上方，第一电极在衬底上的投影包括至少一个第一图形单元。在一实施例中，第一图形单元可包括圆形、椭圆形、哑铃形、葫芦形或矩形，如此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时产生的衍射效应。并且，第一图像单元的形状使得第一电极在第二方向上的尺寸连续变化或者间断变化，从而在第一方向上相邻的两个第一电极在第二方向上的间距连续变化或者间断变化，使得相邻的两个第一电极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下方设置的摄像头拍照得到的图像具有较高的清晰度。
在一个实施例中，位于第一电极上的发光结构包括位于各第一电极上的发光结构。第一电极上的发光结构在衬底上的投影包括至少一个第二图形单元，第二图形单元与第一图形单元相同或不同，使得第一电极上对应设置的发光结构在衬底上的投影与该第一电极在衬底上的投影不同，从而进一步减弱光线通过第一显示区110时产生的衍射效应。
在一实施例中，，第二图形单元包括圆形、椭圆形、哑铃形、葫芦形或矩形。
在一个实施例中，第一方向与第二方向可互相垂直。其中，第一方向可为行方向，第二方向可为列方向。或者，第一方向可为列方向，第二方向可为行方向。
在一个实施例中，第二显示区120内设有多个像素，第二显示区120内的像素的密度可小于子像素组的密度。
本申请实施例提供的显示基板100的第一显示区110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。
本申请实施例还提供了一种显示面板，所述显示面板包括上述任一实施例所述的显示基板及封装层。封装层可包括偏光片，偏光片覆盖第二显示区120，未覆盖第一显示区110，或者偏光片覆盖第一显示区110和第二显示区120。
偏光片可消散显示面板表面的反射光，改善用户的使用体验。第一显示区110不设置偏光片时，可提高第一显示区110的透光率，能够有效保证第一显示区110下方设置的感光器件的正常工作。
在一个实施例中，第一显示区110至少部分被第二显示区120包围。如图1所示，第一显示区110部分被第二显示区120包围，在其他实施例中，第一显示区110全部被第二显示区120包围。
本申请实施例还提供了一种显示装置，显示装置包括设备本体及上述的显示基板或显示面板。设备本体具有器件区，显示面板覆盖在设备本体上。其中，器件区位于第一显示区110下方，且器件区中设置有透过第一显示区110发射或者采集光线的感光器件。
其中，感光器件可包括摄像头和/或光线感应器。器件区中还可设置除感光器件的其他器件，例如陀螺仪或听筒等器件。器件区可以是开槽区，显示面板的第一显示区可对应于开槽区贴合设置，以使得感光器件能够透过该第一显示区进行发射或者采集光线。
上述显示装置可以为手机、平板、掌上电脑、ipod等数码设备。
