技术领域
本申请涉及显示领域，尤其涉及一种显示面板和电子装置。
背景技术
目前，在屏下摄像头技术中，摄像模组位于屏幕下方，外界的光线需要透过屏幕才能到达至摄像模组。而屏幕上布满规则的走线以及周期性排列的单元像素，在光线穿过屏幕时会形成衍射现象，而使得摄像模组成像质量不佳。

目前，在屏下摄像头技术中，由于摄像模组位于屏幕下方，外界的光线需要透过屏幕才能到达摄像模组，使得摄像模组成像。而屏幕上通常会布满规则的走线以及周期性排列的单元像素，在光线穿过屏幕到达至摄像模组时，屏幕的排布的走线以及单元像素会使得光线形成衍射，使得摄像模组成像质量不佳。相关技术中，可通过降低摄像模组对应的屏幕区域的分辨率，也即是，降低摄像模组对应屏幕区域的单元像素个数，从而增加屏幕的透过率，以便于减少光线从外界穿过屏幕时形成光线的衍射现象，改善拍照质量，然而，摄像模组对应的屏幕区域的分辨率的下降影响用户的视觉体验。
有鉴于此，请参阅图1和图2，本申请提供了一种显示面板10，显示面板10包括第一显示区域11和第二显示区域12，第一显示区域11的像素密度与第二显示区域12 的像素密度相同。第一显示区域11包括第一像素单元112，第一像素单元112包括第一像素定义层1121和与第一像素定义层1121对应设置的第一像素阳极1122，第二显示区域12包括第二像素单元122，第二像素单元122包括第二像素定义层1221和与第二像素定义层1221对应设置的第二像素阳极1222；其中，
第一像素定义层1121的开口面积小于第二像素定义层1221的开口面积且第一像素阳极1122的露出面积小于第二像素阳极1222的露出面积。
在本申请的显示面板10中，通过将第一像素单元112中第一像素定义层1121的开口面积小于第二像素单元122中第二像素定义层1221的开口面积以及将第一像素单元112中第一像素阳极1122的露出面积小于第二像素单元122中第二像素阳极1222的露出面积的设置，使得第一显示区域11的光的透过率大于第二显示区域12的透过率，如此，一方面，可减少光线从外界穿过第一显示区域11时而出现的衍射现象，从而能够改善设置在第一显示区域11下的摄像模组拍照的成像效果。另一方面，避免了摄像模组对应的屏幕区域的分辨率的下降而影响用户的视觉体验。
显示面板10可以是有机发光二极管(Organic Light-Emitting Diode，OLED)显示面板10。显示面板10采用有机发光二极管进行显示，可以实现自主发光并且能够对像素点实现定制驱动，无需背光灯，即可实现显示功能，具有轻薄、能耗低、亮度高、发光率好等优点。
请进一步结合图2，具体地，第一显示区域11包括第一基板111、第一像素单元112。其中，第一像素单元112集成在第一基板111上。第一像素单元112包括有第一像素定义层1121和第一像素阳极1122。第一像素阳极1122设置在第一基板111上，第一像素定义层1121位于第一像素阳极1122上，并与第一像素阳极1122正对设置，第一像素定义层1121用于在第一像素阳极1122上界定第一像素单元112的发光区域。第一像素定义层1121开设有开口，第一像素阳极1122部分从第一像素定义层1121的开口露出。第一像素定义层1121的开口面积等于第一像素阳极1122的露出面积。
第二显示区域12包括第二基板121、第二像素单元122。其中，第一基板111和第二基板121连接成一体。第一基板111和第二基板121可以采用柔性基板，如此，使得显示面板10可以制成柔性显示面板10，此外，第一基板111和第二基板121还可采用具有良好的透光性能的材质，从而能够提升显示面板10的透光性能或其它显示需求。
第二像素单元122集成在第二基板121上。第二像素单元122包括有第二像素定义层1221和第二像素阳极1222。第二像素阳极1222设置在第二基板121上，第二像素定义层1221位于第二像素阳极1222上，并与第二阳极像素正对设置，第二像素定 义层1221用于在第二像素阳极1222上界定第二像素单元122的发光区域。第二像素定义层1221开设有开口，第二像素阳极1222部分从第二像素定义层1221的开口露出。第二像素定义层1221的开口面积等于第二像素阳极1222的露出面积。
需要说明的是，在图2所示的实施例中，图1中沿I-I的剖面线经过如图2阴影部分示出的第一显示区域11中第一像素单元11的一个第一像素阳极1122和第二显示区域12中第二像素单元122的三个第二像素阳极1222，而未经过如黑色填充示出的第一显示区域11的两个第一像素阳极1122。
进一步地，第一像素定义层1121的开口面积小于第二像素定义层1221的开口面积且第一像素阳极1122的露出面积小于第二像素阳极1222的露出面积。第一像素定义层1121的开口面积可以为第二像素定义层1221的开口面积的1/2、1/3、2/3、3/4或3/5等，第一像素阳极1122的露出面积可以为第二像素阳极1222的露出面积的1/2、1/3、2/3、3/4或3/5等。第一像素定义层1121的开口面积和第一像素阳极1122的露出面积的具体数值不设。
例如，在一些实施例中，第一像素定义层1121的开口面积为第二像素定义层1221的开口面积的1/2且第一像素阳极1122的露出面积为第二像素阳极1222的露出面积的1/2，从而使得第一像素单元112的面积为第二像素单元122的面积的1/2。如此，既能使得第一显示区域11的透光性能较佳，同时也能保证第一显示区域11能够正常显示。
可以理解，由于像素单元的设计会改变显示面板10的透过率，从而会影响光线穿过显示面板10。需要说明的是，透过率是用于衡量介质(如本申请中第一显示区域11和第二显示区域12)的透光能力的指标。像素单元中影响显示面板10透过率的主要因素包括像素阳极的露出面积以及像素定义层的开口面积大小，若改变像素阳极的露出面积以及像素定义层的开口面积，则显示面板10对应区域的透过率也会跟着变化。因此，通过第一像素定义层1121的开口面积小于第二像素定义层1221的开口面积且第一像素阳极1122的露出面积小于第二像素阳极1222的露出面积的设置，能够使得第一显示区域11的透过率大于第二显示区域12的透过率。如此，光线透过第一显示区域11时形成的衍射现象会小于光线透过第二显示区域12时形成的衍射现象。
在某些实施方式中，第一像素单元112包括多个，多个第一像素单元112呈阵列分布，第二像素单元122包括多个，多个第二像素单元122呈阵列分布，相邻第一像素单元112的间距大于相邻所述第二像素单元122的间距。需要说明的是，相邻两个像素单元之间的间距是指像素单元之间边缘与边缘的最小距离。
请结合图2和图3，具体地，每个第一像素单元112和第二像素单元122均包括至 少一个第一子像素1123、至少一个第二子像素1124和至少一个第三子像素1125，第一像素单元112的第一子像素1123、第二子像素1124和第三子像素1125间隔分布，第二像素单元122的第一子像素1123、第二子像素1124和第三子像素1125间隔分布，且第一子像素1123的面积会大于第二子像素1124的面积，第三子像素1125的面积小于第三子像素1125的面积。例如，在本申请中，每个第一像素单元112和第二像素单元122均包括一个第一子像素1123、两个第二子像素1124和一个第三子像素1125。
进一步地，第一子像素1123包括红色子像素，第二子像素1124包括绿色子像素，第三子像素1125包括蓝色子像素。
在某些实施方式中，每个第一像素单元112的第一子像素1123、第二子像素1124和第三子像素1125均包括一个第一像素阳极1122和一个第一像素定义层1121，每个第二像素单元122的第一子像素1123、第二子像素1124和第三子像素1125均包括一个第二像素阳极1222和一个第二像素定义层1221。
需要说明的是，第一像素单元112中第一像素阳极1122的形状既可以完全相同也可以部分不同，形状可以为圆形、椭圆形或者其它规则或不规则图形，具体地形状不设限制。例如，请参阅图1，在一些实施例中，第一像素单元112中第一像素阳极1122的形状全部为圆形。又例如，请参阅图3，在一些实施例中，第一像素单元112中第一像素阳极1122的形状全部为椭圆形，其中，第一像素单元112内第一子像素1123、第三子像素1125的第一像素阳极1122的长轴朝向与第二子像素1124的第一像素阳极1122的长轴朝向相交。再例如，请结合图4，在一些实施例中，第一像素单元112内第一子像素1123和第三子像素1125的第一像素阳极1122的形状为椭圆形且椭圆形的长轴朝向相同，第二子像素1124中的第一像素阳极1122的形状为圆形。
在某些实施方式中，第一像素单元112内第一子像素1123对应的第一像素阳极1122的露出面积小于第二像素单元122内第一子像素1123对应的第二像素阳极1222的露出面积且第一像素单元112内第一子像素1123对应的第一像素定义层1121的开口面积小于第二像素单元122内第一子像素1123对应的第二像素定义层1221的开口面积。第一像素单元112内第二子像素1124对应的第一像素阳极1122的露出面积小于第二像素单元122内第二子像素1124对应的第二像素阳极1222的露出面积且第一像素单元112内第二子像素1124对应的第一像素定义层1121的开口面积小于第二像素单元122内第二子像素1124对应的第二像素定义层1221的开口面积。第一像素单元112内第三子像素1125对应的第一像素阳极1122的露出面积小于第二像素单元122内第三子像素1125对应的第二像素阳极1222的露出面积且第一像素单元112内第三子像素1125对应的第一像素定义层1121的开口面积小于第二像素单元122内第三子 像素1125对应的第二像素定义层1221的开口面积。
例如，在一些实施例中，第一像素单元112内第一子像素1123对应的第一像素阳极1122的露出面积可以为第二像素单元122内第一子像素1123对应的第二像素阳极1222的露出面积的1/2且第一像素单元112内第一子像素1123对应的第一像素定义层1121的开口面积为第二像素单元122内第一子像素1123对应的第二像素定义层1221的开口面积的1/2。第一像素单元112内第二子像素1124对应的第一像素阳极1122的露出面积为第二像素单元122内第二子像素1124对应的第二像素阳极1222的露出面积的1/2，且第一像素单元112内第二子像素1124对应的第一像素定义层1121的开口面积为第二像素单元122内第二子像素1124对应的第二像素定义层1221的开口面积的1/2。第一像素单元112内第三子像素1125对应的第一像素阳极1122的露出面积可以为第二像素单元122内第三子像素1125对应的第二像素阳极1222的露出面积的1/2，且第一像素单元112内第三子像素1125对应的第一像素定义层1121的开口面积可以为第二像素单元122内第三子像素1125对应的第二像素定义层1221的开口面积的1/2。
在某些实施方式中，第一显示区域11还包括透明导电走线(图中未示出)。具体地，导电走线可以为氧化铟锡(Indium tin oxide，ITO)，ITO是一种透明N型氧化物半导体。如此，第一显示区域11中通过透明导电走线的设置，能够进一步提升第一显示区域11的透光性能。
请结合图1、图2和图5，本申请还提供了一种电子装置100，电子装置100包括上述任意一实施方式的显示面板10。
本申请的电子装置100中，通过将第一像素单元112中第一像素定义层1121的开口面积小于第二像素单元122中第二像素定义层1221的开口面积以及将第一像素单元112中第一像素阳极1122的露出面积小于第二像素单元122中第二像素阳极1222的露出面积的设置，使得第一显示区域11的透光性能大于第二显示区域12的透光性能，如此，一方面，可减少光线从外界穿过第一显示区域11时而出现的衍射现象，从而能够改善设置在第一显示区域11下的感测器20拍照的成像效果。另一方面，避免了感测器20对应的屏幕区域的分辨率的下降而影响用户的视觉体验。
示例性的，电子装置100可以为移动或便携式并执行无线通信的各种类型的计算机系统设备中的任何一种(图4中只示例性的示出了一种形态)。具体的，电子装置100可以为移动电话或智能电话(例如，基于iPhone TM，基于Android TM的电话)，便携式游戏设备(例如Nintendo DS TM，PlayStation Portable TM，Gameboy Advance TM，iPhone TM)、平板电脑、便携式互联网设备、数据存储设备等，电子装置100还 可以为其他的可穿戴设备(例如，智能手环、智能手表、AR眼镜、VR眼镜等)。

在某些实施方式中，电子装置100还包括感测器20，感测器20与显示面板10的第一显示区域11正对设置。
具体地，感测器20可以为摄像模组、指纹识别模组、红外传感器等，感测器20的具体种类不限。例如，在本申请中，感测器20可以为摄像模组，电子装置100可通过感测器20进行摄像，感测器20为电子装置100的前置感测器20，设置在第一显示区域11背光的一侧，如此，在感测器20工作过程中，外界光线可从第一显示区域11穿过而进入感测器20内，使得感测器20在获取到外界光线后能够生成显示图像，并且显示图像中的眩光现象以及衍射现象能够得到改善，提升了用户体验。
