技术领域
本申请属于显示技术领域，具体涉及一种显示面板和电子设备。
背景技术
近年来，随着全面屏的普及，屏幕占比不断提升，电子设备前表面留给摄像头和其它传感器的位置越来越有限。为了提升屏幕占比，屏下摄像头设计方案逐渐被采用。然而，现有的有机发光二极管(Organic Light Emitted Diode，OLED)显示面板由于面板内电路的影响，光线透过率不高，由此导致屏下摄像头在透过屏幕进行拍照时的拍照效果不佳。为了提升光线透过率，通常会减少摄像头正对的显示区域中的像素的数量，因此摄像头正对的显示区域的像素排布设计与其他正常显示区域的像素排布设计存在差异，这种差异会导致显示面板在显示时出现摩尔纹，影响显示效果。
发明内容

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的显示面板和电子设备进行详细地说明。
请参考图1和图2，图1为本申请实施例提供的一种显示面板的层叠结构示意图，图2为本申请实施例提供的显示面板的像素排布示意图。如图1和图2所示，本申请实施例提供的显示面板应用于电子设备，所述显示面板包括衬底基板101，衬底基板101包括第一显示区和第二显示区，所述第一显示区至少部分包围所述第二显示区，第二显示区可以与电子设备的摄像头111正对设置，所述显示面板还包括多个第一像素112和多个第二像素113，其中，多个所述第一像素112位于衬底基板101上的第一显示区，多个所述第一像素112可以呈阵列分布，所述第二像素113包括第二发光器件，多个所述第二像素113的第二发光器件位于衬底基板101上的第二显示区，多个 所述第二像素113的第二发光器件可以呈阵列分布。可选的，所述第一显示区的像素密度大于所述第二显示区的像素密度，也就是说，在布设于第一显示区中的第一像素112的像素密度大于布设于第二显示区中的第二像素113的像素密度。通过减小第二显示区的像素密度，可以提升第二显示区的光线透过率，从而提高摄像头111的拍摄效果。由于第一显示区的第一像素112和第二显示区的第二像素113的排布设计(如像素密度等)不一致，将会导致显示面板产生摩尔纹，造成显示不均、衍射等问题，因此，本申请实施例中的显示面板还包括多个填充图案114，多个填充图案114设置于所述第二显示区的未被第二像素113的第二发光器件所覆盖的区域，填充图案114采用透明材料制作，具体的，可以采用氧化铟锡(Indium tin oxide，ITO)、氧化铟锌(Indium Zinc Oxide，IZO)等透明金属材料制作，从而提高第二显示区的光线透过率，提升摄像头111的拍照效果，并且通过使用无电性功能的填充图案114进行填充，可以避免显示面板产生摩尔纹或衍射或显示不均，从而确保显示面板的显示效果。
由此，在本申请实施例中，通过在第二显示区的未被第二发光器件覆盖的区域设置填充图案，在不影响原有光线透过率的基础上，可以有效提升显示的均匀性，减少因为第一显示区和第二显示区的像素排布差异造成的摩尔纹效应和衍射效应。
如图2所示，在本申请的一些实施例中，第一像素112包括多行多列，第二像素113也包括多行多列，并且第二像素113的行与第一像素112的行对齐，第二像素113的列与第一像素112的列对齐。其中，同一行的相邻的第二像素113所在的两个列之间具有一个第一像素112的列，填充图案114即设置于该列，而同一列的相邻的第二像素113所在的两个行之间具有一个第一像素112的行，填充图案114即设置于该行。也就是说，第一像素112呈行列排布，但是第一像素112只位于第一显示区，而第二显示区应设置第二像素113，因此第二像素113和填充图案114继续按照第一像素112的排布方式进行排布，也即在第二显示区内，第二像素113和填充图案114在行方向上间隔排布，并且第二像素113和填充图案114在列方向上也间隔排布，相当于在第二显示区中利用第二像素113和填充图案114对第一像素112进 行了替换。
请参考图3，为本申请实施例提供的第一像素和第二像素的结构示意图。如图3所示，本申请实施例中，第二像素113还包括第二像素电路1131，第二像素电路1131与第二发光器件1132连接，以驱动第二发光器件1132发光。衬底基板101还包括非显示区，为了提高第二显示区的光线透过率，第二显示区中的第二像素113的第二像素电路1131与第二发光器件1132分离，也即，仅将第二发光器件1132设置在第二显示区，而第二像素电路1131则设置于非显示区，从而避免第二像素电路1131对第二显示区透过的光线的遮挡和反射，以提高与第二显示区正对的摄像头111的拍摄效果。
本申请的一些实施例中，位于所述衬底基板101上的第二显示区走线108中的至少部分采用透明金属氧化物材料制作，相比于现有技术中采用金属合金材料制作的走线，采用透明金属氧化物材料可以避免衍射效应，增加第二显示区透过的光线，可以知道，越多的走线采用透明金属氧化物材料，则第二显示区的光线透过率也将越高。可选的，所述透明金属氧化物可以是ITO、IZO中的任意一种。而所述第二显示区走线108可以包括第二像素电路1131与第二发光器件1132之间的连接线，还可以包括经过第二显示区的数据信号线和初始化信号线。
如图1所示，本申请的一些实施例中，第二发光器件1132包括第二阳极109、阴极105以及位于第二阳极109和阴极105之间的第二有机发光层110，其中，第二阳极109即位于衬底基板101的第二显示区。可选的，所述第二阳极109采用透明金属氧化物材料制作，具体可以选择ITO、IZO中的任意一者。
本申请的一些实施例中，第二像素可以包括第二红色子像素、第二绿色子像素和第二蓝色子像素，所述第二红色子像素、第二绿色子像素和第二蓝色子像素可以共用阴极105，而第二有机发光层110包括第二红色有机发光层1101、第二绿色有机发光层1102和第二蓝色有机发光层1103，第二红色子像素由第二阳极109、第二红色有机发光层1101和阴极105构成，第二绿色子像素由第二阳极109、第二绿色有机发光层1102和阴极105构成，第二蓝色子像素由第二阳极109、第二蓝色有机发光层1103和阴极105构成。
本申请的另一些实施例中，第一像素112包括第一像素电路1121和第一发光器件1122，第一像素电路1121与第一发光器件1122连接，以驱动第一发光器件1122发光，第一像素电路1121和第一发光器件1122均位于衬底基板101的第一显示区，具体的，第一像素电路1121位于衬底基板的第一显示区，而第一发光器件1122则位于第一像素电路1121的背离衬底基板101的一侧。可选的，第一发光器件1122包括第一阳极103、阴极105以及位于第一阳极103和阴极105之间的第一有机发光层104。
其中，第一像素112可以包括第一红色子像素、第一绿色子像素和第一蓝色子像素，所述第一红色子像素、第一绿色子像素和第一蓝色子像素可以共用阴极105，而第一有机发光层104包括第一红色有机发光层1041、第一绿色有机发光层1042和第一蓝色有机发光层1043，第一红色子像素由第一阳极103、第一红色有机发光层1041和阴极105构成，第一绿色子像素由第一阳极103、第一绿色有机发光层1042和阴极105构成，第一蓝色子像素由第一阳极103、第一蓝色有机发光层1043和阴极105构成。在第一阳极103的靠近衬底基板101的一侧设置有像素电路层1120，像素电路层1120中包括多个第一像素电路1121，在第一像素电路1121和衬底基板101之间还设置有反射层102，第二像素112发光时，一部分光线直接从显示面板正面出射，而另一部分光线则射向衬底基板101一侧，并被反射层102反射，当两部分光的共振频率相匹配时，可以产生比原始的发射光强约1.5～2倍的光线，并从显示面板正面出射，这种现象称之为显示面板的微腔效应现象，可以显著提高光效率，可选的，反射层102采用银金属层。
如图2所示，本申请的一些实施例中，至少部分第二像素112的开口区面积小于第一像素111的开口区面积，通过缩小第二显示区中的第二像素112的设计尺寸，可以提升第二显示区的光线透过率，从而提高摄像头111的拍摄效果。
本申请的另一些实施例中，在第一阳极103、第二阳极109均采用ITO材料制作时，为了简化工艺，填充图案114也采用ITO材料制作。
在本申请实施例中，通过在第二显示区的未被第二发光器件覆盖的区域设置填充图案，在不影响原有光线透过率的基础上，可以有效提升显示的均 匀性，减少因为第一显示区和第二显示区的像素排布差异造成的摩尔纹效应和衍射效应。
本申请另一方面实施例还提供了一种电子设备，所述电子设备包括如上述任一项实施例所述的显示面板，还包括摄像头，摄像头位于所述显示面板的第二显示区的正对区域。通过在第二显示区的未被第二发光器件覆盖的区域设置填充图案，在不影响原有光线透过率的基础上，可以有效提升显示面板的显示均匀性，减少因为第一显示区和第二显示区的像素排布差异造成的摩尔纹效应和衍射效应，并且填充图案采用透明材料可以确保光线透过率，从而确保屏下摄像头的成像效果。
本申请实施例中的电子设备可以是移动电子设备，也可以为非移动电子设备。示例性的，移动电子设备可以为手机、平板电脑、笔记本电脑、掌上电脑、车载电子设备、可穿戴设备、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本或者个人数字助理(personal digital assistant，PDA)等，非移动电子设备可以为个人计算机(personal computer，PC)、电视机(television，TV)、柜员机或者自助机等，本申请实施例不作具体限定。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
