下面将结合本申请实施例中的附图1至18，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅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，本领域技术人员在没有付出创造性劳动前提下所获得的所有其他实施例，都属于本申请的保护范围。

后盖600可以位于电路板400远离显示装置200的一侧，也即，后盖600位于电子设备10的最外部，并用于形成电子设备10的外部轮廓。后盖600可以一体成型。在后盖600 的成型过程中，可以在后盖600上形成后置摄像头孔、指纹识别模组安装孔等结构。

请结合图1并参考图2，图2为图1所示的显示装置的第一种结构示意图。显示装置200可以包括相互连接的第一显示区210和第二显示区220。盖板100设置在第一显示区210和第二显示区220的外侧，盖板100覆盖第一显示区210和第二显示区220。第一显示区210的内侧可以设置电子设备10的电路板400、电池500等电子器件。也即，电路板400、电池500等电子器件可以设置在第一显示区210与后盖600之间。第一显示区210的内侧可以设置图像传感器700。图像传感器700的镜头可以朝向第一显示区210设置，图像传感器700用于获取透过第一显示区210的外界光信号进行成像。

可以理解的是，第一显示区210的面积可以远小于第二显示区220，第二显示区220可以围绕第一显示区210设置，第一显示区210周缘可以都与第二显示区220邻接。第一显示区210可以位于第二显示区220的中间。第二显示区220也可以部分围绕第一显示区210，第一显示区210的部分边缘与第二显示区220邻接。第二显示区220的边角也可以为不规则形状，例如具有一个缺口，第一显示区210可以位于该缺口内。

需要说明的是，本申请实施例中的第二显示区220可以作为显示装置200的主要显示区，第一显示区210可以作为显示装置200的辅助显示区，第二显示区220可以为主动式驱动(AMOLED)显示区，第一显示区210可以为主动式驱动(AMOLED)显示区或被动式驱动(PMOLED)显示区。PMOLED的显示效果虽然低于AMOLED，但是因为第一显示区210的面积很小，显示的内容也很少，而且第一显示区210位于显示装置200的边缘，显示的内容重要性较低，所以第一显示区210可以采用PMOLED。被动式驱动的第一显示区210只需要一个薄膜晶体管(TFT)驱动，不透光的薄膜晶体管数量极少，可以极大的提升第一显示区210的透光率。
需要理解的是，在本申请的描述中，诸如“第一”、“第二”等术语仅用于区分类似的对象，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
请参阅图3，图3为图2所示的显示装置沿P1至P2方向的第一种剖面示意图。显示装置200可以包括依次层叠设置的驱动电路层291、第一透明导电层292、阳极层293、像素定义层294、公共电极层295等层状结构。
像素定义层294包括第一像素定义区域2941，该第一像素定义区域2941可以对应显示装置200的第一显示区210设置。请结合图3并请参考4，图4为图3所示的像素定义层的一种结构示意图。第一像素定义区域2941具有多个像素孔，每个像素孔内设置有像素单元，像素单元包括有机发光材料，第一像素定义区域2941可以形成有至少一个第一像素单元a1，该第一像素单元a1可以包括一个或多个子像素201，例如，第一像素单元a1可以包括红光子像素、绿光子像素和蓝光子像素。子像素201可以至少为椭圆形子像素或圆形子像素，以使得第一像素单元a1可以包含椭圆形子像素或圆形子像素。
阳极层293可以层叠设置于像素定义层294一侧，阳极层293与驱动电路层291电连接，并用于控制驱动电路层291的每一个第一驱动单元2911。阳极层293包括多个透明阳极2931，多个透明阳极2931可以对应显示装置200的第一显示区210设置，也即，多个透明阳极2931可以对应第一像素定义区域2941设置。一个透明阳极2931可以与像素定义层294的一个子像素201电连接。
驱动电路层291间隔地设置于阳极层293背离像素定义层294的一侧，驱动电路层291在对应于第一像素定义区域2941之外的区域内设置有多个第一驱动单元，其中，所谓对应于第一像素定义区域2941之外的区域可以是指对应第一显示区210外的区域，也可以是对应第二显示区220的区域。每一第一驱动单元2911用于驱动一个子像素201。第一驱动单元2911包括不透光的部分如薄膜晶体管TFT。
第一透明导电层292设置于阳极层293和驱动电路层291之间。第一透明导电层292形成有多条曲线形的透明导电线路2921，该透明导电线路2921可以部分对应第一显示区210设置、部分对应第二显示区设220置。每一个透明阳极2931通过一条透明导电线路2921电连接至一个第一驱动单元2911。
公共电极层295设置在像素定义层294上，公共电极层295可以对应第一显示区210和第二显示区220设置，阳极层293和公共电极层295分别设置在像素定义层294的两侧，并与驱动电路层291的多个第一驱动单元2911共同驱动多个子像素201。
本申请实施例的显示装置200，驱动电路层291可以与电源正极电连接，公共电极层295可以与电源负极电连接，当电源正极和电源负极通电时，电流会在驱动电路层291、阳极层293、像素定义层294和第一透明导电层292中流动，以使得在电流作用下，像素定义层294的子像素201被驱动并可以发出光线，以实现显示装置200的显示功能。
本申请实施例的电子设备10，当图像传感器700设置于显示装置的内侧时，外部光线经过显示装置200的第一显示区210时，对应第一显示区210的阳极层293内设置的是透明阳极2931，透明阳极2931对外部光线的衍射干扰较小；并且，不透光的第一驱动单元2911设置对应第一显示区210外部的区域，不透光的第一驱动单元2911完全不会影响外部光线的入射，使得外部光线在第一显示区210的透过率较高；同时，外部光线经过圆形或 椭圆的子像素201时，外部光线形成的衍射光谱中，能量更够更加集中在主级衍射条纹内，各次级衍射条纹的能量较低，各次级衍射条纹会更少，从而可以减轻衍射现象。
为了进一步地减轻衍射干扰，请参考图5，图5为图4所示的子像素的第一种结构示意图。本申请实施例的显示装置200，每一子像素201可以包括相互连接主体部2011和边缘部2012。其中，在平行于像素定义层294的方向上，主体部2011的横截面可以为圆形或椭圆形。边缘部2012的横截面可以近似为环形，该环形可以包括外部轮廓和内部轮廓，该内部轮廓环绕并贴合主体部2011的外周缘，该内部轮廓可以是闭合的圆形或椭圆形曲线；该外部轮廓可以包括多条曲率不同的曲线，多条曲率不同的曲线首位相连可以形成环绕主体部2011的闭合曲线。
可以理解的是，多条曲率不同的曲线可以形成环绕主体部2011的不规则闭合曲线。该不规则闭合曲线可以是指该曲线不为规则的正三角形、正四边形等正多边形；该不规则闭合曲线也不为常见的三角形、正方形、长方形、平行四边形；该不规则闭合曲线也不为规则的圆形、椭圆形；该不规则曲线也不为多个相同弧形连接而成的曲线。
可以理解的是，当边缘部2012的外部轮廓包括多条曲线时，任意相邻的两条曲线的曲率可以不同。进而，光线在经过任意相邻的两条曲线时，形成的衍射现象更加容易相互抵消，从而，光线在经过整个边缘部2012时，其产生衍射的概率大大降低，可以较大限度的减轻衍射现象。
本申请实施例的显示装置200，子像素201包括由不同曲率的曲线构成的边缘部2012时，受到不同曲率的曲线的影响，当外界光线经过子像素201的边缘部2012时，边缘部2012上不同部位形成的衍射现象会相互抵消，进而可以减轻衍射条纹的形成，降低衍射干扰。
其中，请参考图6，图6为图4所示的子像素的第二种结构示意图。本申请实施例的显示装置200，每一子像素201可以包括相互连接的主体部2011和凸起部2013。凸起部2013可以包括多个间隔设置的凸起，多个凸起环绕并凸出主体部2011的外周缘设置。
可以理解的是，多个凸起可以由多条曲率不同的曲线构成，每一凸起可以从主体部2011的外边缘朝着远离主体部2011的方向延伸而成。此时，子像素201的外周缘可以包括多个凸起。
可以理解的是，凸起的数量可以在20至30个左右，此时，边缘部2012的外周缘可以包括20至30条首位相互连接的曲线，子像素201的外边缘可为不规则的曲线。
本申请实施例的显示装置200，子像素201包括由多个凸起构成的外边缘时，由于凸起的弯折曲率更大，当外界光线经过子像素201的边缘部2012时，子像素201上不同凸起形成的衍射现象会相互抵消，进而可以减轻衍射条纹的形成，降低衍射干扰。
其中，请继续参考图5和图6，子像素201在平行于像素定义层294的方向上的横截面的直径可以为目标波长一半的非整数倍。可以理解的是，目标波长的光线可以是某一波段范围内的一种光线。例如，当目标波长的光线为可见光波段(380纳米至750纳米波段)的光线，此时，子像素201的横截面直径可为整个可见光波段范围内任一波长一半的非整 数倍，也即，子像素201的横截面直径可以避开整个波段范围内任一波长一半整数倍。
可以理解的是，目标波长一半的非整数倍是指子像素201的横截面的直径不为二分之一的目标波长的整数倍，也即，直径D≠n·1/2·λ(目标波长)，n为正整数。
可以理解的是，当子像素201在平行于像素定义层294的方向上的横截面为圆形时，也即，子像素201为圆柱像素时，该子像素201在平行于像素定义层294的方向上的横截面上任意经过中心的两个点之间的直径均可以为目标波长一半的非整数倍。子像素201的中心可以是子像素201在平行于像素定义层294的方向上的圆形横截面的圆心。
可以理解的是，当子像素201在平行于像素定义层294的方向上的横截面为椭圆形时，也即，该子像素201为椭圆柱像素时，该子像素201在平行于像素定义层294的方向上的横截面上任意经过中心的两个点之间的直径也可以为目标波长一半的非整数倍。子像素201的中心可以是子像素201在平行于像素定义层294的方向上的椭圆形横截面的上长轴和半轴的交点。
基于光学原理，显示装置200外部的光线经过子像素201时，由于子像素201的透过率与空气、像素间隔区域的透过率不同，子像素201相对空气、像素间隔区域为障碍物，光线在经过障碍物的子像素201时会偏离原来直线传播轨迹而形成衍射现象。本申请实施例的显示装置200，子像素201的横截面为圆形或椭圆形像素，当子像素201阻挡目标波长的光线时，由于子像素201的横截面的直径为目标波长一半的非整数倍时，可以使得能量更加集中在主级衍射条纹内，各次级衍射条纹的能量较低，各次级衍射条纹会更少，从而可以减轻衍射现象。
其中，请参考图7，图7为图4所示的子像素的第三种结构示意图。本申请实施例的显示装置200，第一像素定义区域2941内的第一像素单元a1可以包括间隔设置的第一子像素2014、第二子像素2015和第三子像素2016，或者说，子像素201可以包括第一子像素2014、第二子像素2015和第三子像素2016。在平行于像素定义层294的方向上，第一子像素2014和第二子像素2015的横截面积可以大于第三子像素2016的横截面积。
可以理解的是，第一子像素2014、第二子像素2015、第三子像素2016可以由有机发光材料制成，其在电流作用下可以自发光。例如，第一子像素2014可以发出第一颜色的光线，第二子像素2015可以发出第二颜色的光线，第三子像素2016可以发出第三颜色的光线。第一颜色、第二颜色和第三颜色可以各不相同。
可以理解的是，在平行于像素定义层294的方向上，第一子像素2014和第二子像素2015的横截面可以为圆形，第三子像素2016的横截面可以为椭圆形，其中，椭圆形的长轴尺寸可以与圆形的直径相等，椭圆形的短轴尺寸可以小于圆形的直径，以使得第三子像素2016的横截面积小于第一子像素2014、第二子像素2015的横截面积。
可以理解的是，第一子像素2014、第二子像素2015、第三子像素2016的厚度可以相同，也即，在第一像素定义区域2941内，第一子像素2014、第二子像素2015、第三子像素2016的上表面可以处以同一平面，第一子像素2014、第二子像素2015、第三子像素2016的下表面也可以处于同一平面。
本申请实施例的显示装置200，在平行于像素定义层294的方向上，第三子像素2016的横截面小于第一子像素2014和第二子像素2015，使得第三子像素2016占据的空间更小，由于光线在经过障碍物时才会发生衍射，进而，占据空间更小的第三子像素2016产生衍射的概率更小，从而可以降低整个显示装置200产生衍射的概率，降低衍射干扰。
其中，在平行于像素定义层294的方向上，当第一子像素2014和第二子像素2015的横截面积大于第三子像素2016的横截面积时，第一子像素2014、第二子像素2015和第三子像素2016可以采用不同的发光材料制作，使得第一子像素2014可以具有第一发光衰减频率，第二子像素2015可以具有第二发光衰减频率，第三子像素2016可以具有第三发光衰减频率，并且，第一发光衰减频率、第二发光衰减频率可以大于第三发光衰减频率。
本申请实施例的显示装置200，当第一子像素2014和第二子像素2015的发光衰减频率大于第三子像素2016的发光衰减频率时，经过相同使用时长后，在相同电流作用下，单位面积的第一子像素2014和第二子像素2015发出的光线的强度会减弱，会小于单位面积第三子像素2016发出光线的强度。由于第一子像素2014和第二子像素2015的横截面积大于第三子像素2016的横截面积，使得，第一子像素2014和第二子像素2015的发出的总体光线总强度可以与第三子像素2016发出的光线总强度相同，进而，本申请实施例的显示装置200，第一子像素2014、第二子像素2015和第三子像素2016可以发出相同亮度的光线，能对像素的衰减进行补偿，可以提高整个显示装置200的使用寿命。
其中，请参考图8，图8为图4所示的子像素的第四种结构示意图。本申请实施例的显示装置200，第一显示区210内可以包括间隔设置的多个子像素201，也即，多个子像素201间隔设置在第一像素定义区域2941内。其中，在平行于像素定义层294的方向上，子像素201的横截面直径d可以不为相邻两个子像素201之间的间距a的二分之一，也即，子像素201的横截面直径可以大于或小于相邻两个子像素201之间的间距a的二分之一。
可以理解的是，在平行于像素定义层294的方向上，子像素201的横截面直径可以参见前述的记载，在此不再赘述。可以理解的是，如图8所示，在平行于像素定义层294的方向上，相邻两个子像素201之间的间距a可以是位于两个子像素201边缘上的两点之间的距离，其中，两个子像素201边缘上的两点的连线会分别经过两个子像素201的圆心。
可以理解的是，在平行于像素定义层294的方向上，本申请实施例的两个子像素201的横截面可以均是椭圆形，也可以均是圆形，还可以一个为圆形，一个为椭圆形。当然，本申请实施例的两个子像素201还可以是其他的形状，本申请实施例对其具体形状并不做限定。
可以理解的是，假设第一显示区210的像素间隔区域的折射率为n 1，厚度为d 1，子像素201的折射率为n 2，厚度为d 2，两相邻子像素201的间距为a，子像素201的直径为d，光源距离第一显示区210的距离为n 0，则光线经过第一显示区210的透过率函数可以表示为：
Figure PCTCN2021110586-appb-000001
分别改变a和d的值，可以得到不同的衍射图样。示例性的，请参考图9至图11，其中，图9为本申请实施例的第一显示区的第一种衍射图样，图10为本申请实施例的第一显示区的第二种衍射图样，图11为本申请实施例的第一显示区的第三种衍射图样。并且，在图9至图11中，左边为第一显示区210的衍射光强包络图，右边为第一显示区210的衍射级次分布图。
在图9中，两相邻子像素201的间距为a为18微米，子像素201的直径为d为23微米。在图10中，两相邻子像素201的间距为a为18微米，子像素201的直径为d为33微米。在图11中，两相邻子像素201的间距为a为18微米，子像素201的直径为d为63微米。
对比图9至图11可以看出，衍射级次间距和d成反比关系，随着d的增大，衍射级次间距在逐渐缩小，当a与d的比例接近a＝0.5d时，±1级衍射光强最强。基于此，本申请实施例的显示装置200，子像素201的横截面的直径可以不为相邻两个子像素201之间的间距a的二分之一，光线在经过第一显示区210时，可以使得次级衍射光强较弱，从而可以减轻衍射。
其中，请参考图2并请参考图12，图12为图2所示的显示装置沿P1至P2方向的第二种剖面示意图。
显示装置200的第一显示区210包括依次层叠设置的基板296、驱动电路层291、第一平坦化层298、第一透明导电层292、第二透明导电层297、阳极层293、像素定义层294、公共电极层295、第二平坦化层299和触控层290。

第二透明导电层297设置于阳极层293和驱动电路层291之间。第二透明导电层297可以和第一透明导电层292层叠设置，也即，第二透明导电层297可以设置在驱动电路层291与第一透明导电层292之间，第二透明导电层297也可以设置在第一透明导电层292与阳极层293之间。第二透明导电层297包括多个透明导电子层，每一透明导电子层将一个透明阳极2931电连接至一个第一驱动单元2911。随着第一显示区210的分辨率的提高，受到电子设备10体积的限制，第一透明导电层292并不能完全连接每一个子像素201，本申请实施例中，第一透明导电层292和第二透明导电层297的相互配合可以连接于高分辨率的第一显示区210的每一子像素201。
第一平坦化层298，设置于阳极层293和驱动电路层291之间，第一平坦化层298上设有多个在平坦化层厚度方向上贯穿第一平坦化层298的过孔2981，过孔2981用于穿过透明导电线路2921以将第一驱动单元2911和透明阳极2931电连接。透明导电线路2921通过第一平坦化层298上的过孔2981来走线，透明导电线路2921的走线可以更短，以进一步降低透明导电线路2921对光线的干扰。
公共电极层295设置在发光层294上，阳极层293和公共电极层295设置在子像素201两侧，并共同驱动子像素201。公共电极层295可以采用高透光率的ITO材料。

在第二平坦化层299上还可以设置触控层290，触控层290可以用于检测用户触控操作。在触控层290上还可以设置偏光片(图中未示出)，偏光片可以用于防止内部光线透射出去，防止用户看到内部的驱动单元等元件。触控层290和偏光片可以贴合在一起，然后再设置在平坦化层296上。
需要说明的是，在其他一些实施例中，可以根据需要增加或减少部分结构，本申请实施例在此不做限定。例如，可以减少触控层290、偏光片中的至少一项。又例如，可以在第二平坦化层299和触控层290之间增加一层保护层，保护层可以采用与基板296一样的材料。
第一显示区210内各层结构中除了驱动电路层291中的第一驱动单元2911，都采用透光材料，以提高第一显示区210的透光率。例如，第一显示区210的基板296、像素定义层294、公共电极层295、第一平坦化层298、第二平坦化层299、触控层290都可以采用透光材料制成，阳极层293中的信号线可以采用ITO或纳米银等透光材料制。驱动电路层291的TFT无法采用透光材料，驱动电路层291中除了TFT其他部分也可以采用透光材料。可以理解的是，通过提高材料的透光率以及改变布线的排布以提高第一显示区210的方案均在本申请的范围内。
需要说明的是，第二显示区220可以采用和第一显示区210类似的层叠结构，具体可参阅上述实施例，在此不再赘述。第二显示区220的基板、像素定义层、公共电极层、平坦化层、触控层等中的至少一项可以和第一显示区210采用一样的透光材料，示例性地，基板可 以采用玻璃或树脂等透光材料。第二显示区220的基板、像素定义层、公共电极层、平坦化层、触控层等中的至少一项可以和第一显示区210采用不同的材料，例如，第二显示区220的阳极层293中的信号线可以采用钼、钼铝钼、Ag等金属或合金材料，第二显示区220没有设置遮光块，第二显示区220金属阳极可以采用金属材料，比如Mg、Ag、Al。第二显示区220的公共电极层可以采用Mg、Ag等材料。第二显示区220的公共电极层和第一显示区210的公共电极层边缘处是相连的，共同构成一个完整的公共电极层295。其中，第二显示区220的发光层包括多个子像素，第二显示区220的子像素的材料可以和第一显示区210的子像素201的材料相同，透光率也相同。第二显示区220的子像素也可以和第一显示区210的子像素201不同，以实现第一显示区210的透光率大于第二显示区220的透光率。
其中，请再次参考图4，本申请实施例的显示装置200，像素定义层294还可以包括第二像素定义区域2942，该第二像素定义区域2942可以对应于驱动电路层291，并在对应于第一像素定义区域2941之外的区域，也即，第一驱动单元2911在像素定义层294的正投影位于第二像素定义区域2942。
可以理解的是，第二像素定义区域2942可以形成有至少一个第二像素单元a2，当第二像素单元a2包括多个时，多个第二像素单元a2可以间隔设置。其中，第二像素单元a2可以包括多个第四子像素202，例如，第二像素单元a2可以包括红光子像素、绿光子像素和蓝光子像素。在平行于像素定义层294的方向上，第四子像素202的横截面积可以大于子像素201的横截面积。
可以理解的是，第二像素定义区域2942可以设置于第二显示区220，该第二像素定义区域2942可以与第一像素定义区域2941相邻设置并相互连接。第一像素定义区域2941和第二像素定义区域2942可以位于盖板100的内侧，以使盖板100可以保护第一像素定义区域2941和第二像素定义区域2942。
可以理解的是，第一像素定义区域2941与第二像素定义区域2942可以同层设置。所谓同层设置，可以是指第一像素定义区域2941的外表面可以与第二像素定义区域2942的外表面处于同一平面、第一像素定义区域2941的内表面可以与第二像素定义区域2942的内表面处于同一平面。
可以理解的是，在平行于像素定义层294的方向上，第二像素单元a2的第四子像素202的横截面可以如第一像素单元a1的子像素201一样为圆形或椭圆形，以减轻衍射干扰。
可以理解的是，驱动电路层291对应于第二像素定义区域2942的区域内设置有多个第二驱动单元(图未示)，每一第二驱动单元与第二像素单元a2的一个第四子像素202电连接以驱动一个第四子像素202。
可以理解的是，阳极层293可以设置多个金属阳极(图未示)，金属阳极可以设置于第二显示区220，每一金属阳极可以与第二像素单元a2的一个第四子像素202电连接。显示装置200也可以包括导电层(图未示)，导电层设置于第二显示区220，导电层形成有多条曲线形的导电线路，每一金属阳极通过一条导电线路电连接至一个第四子像素202。
本申请实施例的显示装置200，不透光的第一驱动单元2911正投影位于第二像素定义 区域2942，不透光的第一驱动单元2911完全不会影响入射至第一像素定义区域2941的外部光线，使得外部光线在与第一像素定义区域2941对应的区域时的透过率较高。并且，第二像素单元a2的横截面积大于子像素201的横截面积，子像素201的尺寸小于第二像素单元a2的尺寸，进而，子像素201占据的面积更小，第一显示区210内的像素间隔更大，第一显示区210的透过率更高，衍射现象发生的概率更低。
可以理解的是，在平行于像素定义层294的方向上，当第四子像素202的横截面积可以大于子像素201的横截面积时，可以选择特定衰减频率的发光材料，使得第四子像素202的衰减频率大于子像素201的衰减频率，进而可以保证第一显示区210和第二显示区220显示的一致性，第一显示区210和第二显示区220在显示信息时不会出现明显的边界感。
其中，第一显示区210的透过率可以大于第二显示区220的透过率。可以理解的是，实现第一显示区210的透过率大于第二显示区220的透过率的方式可以有多种。
例如，第一显示区210可以包括多个子像素201，第二显示区220可以包括多个第四子像素202，多个子像素201的像素密度可以小于多个第四子像素202的像素密度，以使得第一显示区210内多个子像素201之间的间隔区域更大，进而导致可透过光线的区域增多，从而实现第一显示区210的透光率大于第二显示区220的透光率。
可以理解的是，为了进一步提高第一显示区210的透光率，第一显示区210的子像素201采用透光材料。例如采用氧化铟锡材料。
可以理解的是，多个第四子像素202和多个子像素201均可以采用阵列的方式排布。第一显示区210的子像素201的排列方式可以为标准RGB排列、Pentile排列或Delta排列中的一种，第二显示区220的第四子像素202的排列方式可以为标准RGB排列、Pentile排列或Delta排列中的一种。需要说明的是，第一显示区210中子像素201还可以采用其他排列方式，第二显示区220中第四子像素202还可以采用其他排列方式。
再例如，在显示装置200中设置多个驱动电路层291，第一驱动层(图未示)与子像素201连接并驱动子像素201，第二驱动层(图未示)与第四子像素202连接并驱动第四子像素202，第一驱动层设置于第二驱动层的内侧，第二驱动层设有贯穿其厚度方向的过孔2981，驱动走线穿过该过孔2981处将第一驱动层内的第一驱动单元2911与子像素201电连接。
可以理解的是，驱动单元可以采用2T1C、5T1C、7T1C等驱动电路中的一种。诸如第一驱动单元2911可以采用2T1C、5T1C、7T1C中的一种，第二驱动单元采用2T1C、5T1C、7T1C中的一种。其中，T表示薄膜晶体管，其中C表示电容。为了提高第一显示区210的透光率，设置在第一显示区210的第一驱动单元2911可以为比第二显示区220的主驱动单元简略的驱动电路，比如第一驱动单元2911包括的薄膜晶体管的数量少于第二驱动单元的薄膜晶体管的数量。诸如第一驱动单元2911可以采用2T1C、5T1C中的一种，第二驱动单元采用7T1C。第一驱动单元2911中不透光的薄膜晶体管的数量更少，第一显示区210中不透光的部分更少，可以提高第一显示区210的透光率。
又例如，第一显示区210和第二显示区220可以具有相同的像素物理结构，但是，第 一显示区210中的多个子像素201可以并联，可以并联连接到一个信号线，形成一像素集合，可以减少子像素201与信号线连接的信号线条数，从而可以提高第一显示区210的透光率。
可以理解的是，以上仅为实现第一显示区210的透光率大于第二显示区220的透光率的方案举例，本申请实施例的方案并不局限于此，其他可以实现第一显示区210的透光率大于第二显示区220的透光率的方案都在本申请的保护范围内。
其中，请参考图13，图13为图1所示的显示装置的第二种结构示意图。显示装置200还可以包括非显示区230。非显示区230可以位于第二显示区220的周缘，非显示区230可以与第二显示区220相互连接。
可以理解的是，第一驱动单元2911位于该非显示区230内，透明导电线路2921分别与子像素201和第一驱动单元2911连接，使得第一驱动单元2911可以驱动子像素201发光。
可以理解的是，非显示区230可以没有显示功能，并不能显示画面。可以理解的是，非显示区230可以设置在电子设备10的顶部区域，非显示区230也可以设置在电子设备10的底部区域，非显示区230也可以同时设置在电子设备10的顶部和底部区域，非显示区230也可以设置电子设备10的顶部、底部以及两个相对设置的侧部。
可以理解的是，透明导电线路2921可以为弧形走线。透明导电线路2921以采用透明材料制成，例如采用氧化烟锡材料制成。
本申请实施例的显示装置200，将第一驱动单元2911设置于非显示区230，第一驱动单元2911不用占据第一显示区210的空间，第一显示区210的透过率可以更高，外部光线也不会在第一显示区210内遇到第一驱动单元2911而形成衍射现象，进而，也可以降低对第一显示区210的衍射干扰。同时，透明导电线路2921用弧形走线，外部光线遇到弧形走线，弧形走线上的不同部位形成的衍射现象会相互抵消，也可以减轻衍射条纹的形成，降低衍射干扰。
其中，第一显示区210和第二显示区220的第一像素定义区域2941和第二像素定义区域2942，可以为OLED显示层，OLED显示层可以包括层叠设置的空穴传输层、有机发光层、电子传输层等层状结构，当在阳极层293和公共电极层295之间通过电流时，由电极注入的电子和空穴在发光层中复合形成激子，激子辐射退激发而发出光子并产生可见光。
由于OLED像素可以自发光，其发出的光线可以朝着显示装置200的外部传输并被人眼吸收。其发出的光线也可以朝着显示装置200内部传输，传输至显示装置200内部的光线一般被称为屏幕漏光，这一部分光线没有被人眼接收，一方面会影响显示装置200的亮度，另一方面也使得像素的透过率变低而产生衍射现象。为了提高显示装置200的亮度，相关技术中往往是在阳极层293中添加反光材料，例如银材料，光线经过OLED像素时，在银材料的反射作用下，可以将第一像素定义区域2941和第二像素定义区域2942的屏幕漏光反射至显示装置200外部。
在阳极层293中添加反光材料可以提高显示装置200的亮度，但是随之而来的是，会 降低显示层中像素的透光率，当光线经过显示装置200时，会形成衍射现象，该衍射会严重图像传感器700的采光及拍摄效果。
因此，请参考图14，图14为图2所示的显示装置沿P1至P2方向的第三种剖面示意图。本申请实施例的显示装置200，第二显示区220可以在第二像素定义区域2942的阳极层293内设置反光材料而在第二像素定义区域2942形成反光层270，以保证显示装置200的显示亮度。
可以理解的是，反光层270也可以设置在第二像素定义区域2942的一侧，例如内侧，以保证显示装置200的显示亮度。
可以理解的是，第一像素定义区域2941可以在阳极层293内不设置反光材料，从而不形成反光层270。
为了同时兼顾显示亮度和图像传感器700拍摄效果，本申请实施例的显示装置200还可以包括阻挡件240，该阻挡件240可以设置在第一像素定义区域2941与图像传感器700之间。该阻挡件240可以在第一状态与第二状态下切换，处于第一状态下的阻挡件240可以将第一像素定义区域2941、第二像素定义区域2942发出的光线反射至显示装置200外或者被吸收；处于第二状态下的阻挡件240可以使得至少部分环境光能穿过显示装置200并进入到图像传感器700内。
其中，请参考图15和图16，图15为图1所示的电子设备沿M1至M2的第一种剖面示意图，图16为图1所示的电子设备沿M1至M2的第二种剖面示意图。该阻挡件240可以是电致反射层241，该电致反射层241可以设置于显示装置200例如第一像素定义区域2941与图像传感器700之间，该电致反射层241可以正对第一像素定义区域2941、第一显示区210设置。并且，在电流作用下，电致反射层241可以实现从低透光率的着色状态到高透光率的消色状态之间的可逆变化。
例如，如图15所示，在不通电的状态下，本申请实施例的电致反射层241可以呈现有颜色的第一状态，在第一状态下，电致反射层241具有较低的透光率，第一像素定义区域2941、第二像素定义区域2942发出的光线不能透过该电致反射层241；并且，该电致反射层241可以优选具有反射功能的材料制作，以使得在第一状态下，该电致反射层241还可以将有机发光层发出的光线反射至显示装置200外。
如图16所示，在通电的状态下，本申请实施例的电致反射层241可以呈现出透明的第二状态，在第二状态下，电致反射层241具有较高的透光率，环境光可以透过该电致反射层241并进入到图像传感器700中，进而，在第二状态下，该电致反射层241可以使得至少部分环境光能穿过显示装置200并进入到图像传感器700内。
其中，该阻挡件240也可以是电致吸收层(图未示)，该电致吸收层可以设置于显示装置200例如第一像素定义区域2941与图像传感器700之间，该电致吸收层可以正对第一像素定义区域2941、第一显示区210设置。并且，在电流作用下，电致吸收层也可以实现从低透光率的着色状态到高透光率的消色状态之间的可逆变化。
例如，在不通电的状态下，本申请实施例的电致吸收层可以呈现有颜色的第一状态， 在第一状态下，电致吸收层具有较低的透光率，第一像素定义区域2941、第二像素定义区域2942发出的光线不能透过该电致吸收层，并可被电致吸收层吸收。在通电的状态下，本申请实施例的电致吸收层可以呈现出透明的第二状态，在第二状态下，电致吸收层具有较高的透光率，环境光可以透过该电致吸收层并进入到图像传感器700中，进而，在第二状态下，该电致吸收层可以使得至少部分环境光能穿过显示装置200并进入到图像传感器700内。
其中，请参考图17和图18，图18为图1所示的电子设备沿M1至M2的第三种剖面示意图，图18为图1所示的电子设备沿M1至M2的第四种剖面示意图。该阻挡件240也可以是反光元件242，电子设备10还可以包括一驱动机构260，该驱动机构260可以与反光元件242电连接，在驱动机构260的作用下，该反光元件242可以在第一状态与第二状态之间切换，第一状态为反光元件242正对第一像素定义区域2941设置，第二状态为反光元件242至少部分错开第一像素定义区域2941设置。
如图17所示，当反光元件242处于第一状态时，该反光元件242的反光面可以正对第一像素定义区域2941的发光面设置，该反光元件242的反光面在第一像素定义区域2941上的投影可以覆盖该第一像素定义区域2941和发光面，以使得反光元件242可以将第一像素定义区域2941发射光线全部反射至显示装置200的外部。
如图18所示，当反光元件242处于第二状态时，该反光元件242的反光面可以与第一像素定义区域2941的发光面完全错开或部分错开设置。该错开设置可以是指反光元件242在第一像素定义区域2941上的投影与第一像素定义区域2941完全不相交，反光面在第一像素定义区域2941的投影与发光面在第一像素定义区域2941的投影完全不相交。此时，反光元件242完全未遮挡第一像素定义区域2941，第一像素定义区域2941发出的光线可以不经反射而直接进入到显示装置200的内部并被图像传感器700接收并检测。
可以理解的是，该错开设置也可以是指反光元件242在第一像素定义区域2941上的投影与第一像素定义区域2941部分不相交，反光面在第一像素定义区域2941的投影与发光面在第一像素定义区域2941的投影部分不相交。此时，反光元件242未完全遮挡第一像素定义区域2941，第一像素定义区域2941发出的光线中部分光线可以不经反射而直接进入到显示装置200的内部并被传感器接收并检测。
当然，该错开设置也可以是指反光元件242的反光面与发光面之间呈预设夹角，该预设夹角可以大于零度而小于三百六十度，以使得该反光面并没有完全正对发光面设置，此时第一像素定义区域2941发出的光线中存在部分光线可以穿过反光元件242而未被反射，从而可以进入显示装置200的内部并被图像传感器700接收并检测。
可以理解的是，驱动机构260可以是电机驱动机构，示例性的，驱动机构260可以包括电机和滑轨，滑轨可以设置在第一像素定义区域2941的一侧例如内侧，电机的转轴可以与反光元件242连接，电机带动反光元件242在滑轨上滑动，以使反光元件242可以正对第一像素定义区域2941设置并覆盖第一显示区210，或者可以使反光元件242错开第一像素定义区域2941设置并远离第一显示区210。
示例性的，驱动机构260也可以是电磁驱动机构，例如，驱动机构260可以包括两块磁铁、弹簧和电磁电路，两块磁铁分别设置在反光元件242与第一像素定义区域2941上，弹簧的一端与反光元件242连接，弹簧的另一端可固定在第二显示区220的结构上。当电磁电路接通时，反光元件242和第一像素定义区域2941在磁引力的作用下，反光元件242正对第一像素定义区域2941设置并覆盖在第一显示区210，此时弹簧被拉伸。当电磁电路断开时，反光元件242与第一像素定义区域2941之间的磁引力消失，反光元件242被弹簧拉回至初始位置，也即，反光元件242与第一像素定义区域2941错开设置并远离第一显示区210。
当然，本申请实施例的驱动机构260并不局限于上述举例，驱动机构260也可以是其他的驱动机构，例如气缸驱动机构、电机齿轮驱动机构、电机皮带驱动机构等。凡是可使反光元件242在第一状态与第二状态之间切换的驱动机构260都在本申请的保护范围内。
本申请实施例的显示装置200和电子设备10，阻挡件240可以在第一状态和第二状态之间切换，当阻挡件240处于第一状态时，阻挡件240可以完全遮挡第一像素定义区域2941，阻挡件240可以将第一像素定义区域2941发出的光线完全反射至显示装置200外或完全吸收，从而可以保证显示装置200的亮度及降低反射；当阻挡件240处于第二状态时，阻挡件240不能完全遮挡第一像素定义区域2941，光线可以不经过阻挡件240而直接进入到显示装置200内并被图像传感器700接收。从而，一方面，可以提高显示装置200的透光率，另一方面，第一像素定义区域2941的多个子像素201不会形成衍射光栅，也不会影响图像传感器700的拍摄效果。
以上对本申请实施例提供的显示装置及电子设备进行了详细介绍。本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请。同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
