像素结构中的像素孔2502和有机发光体2522均为周期性结构，为方便理解，以一维情况为例，请结合图3，像素结构的透过率函数与远场衍射光强构成傅里叶变换关系。假设每个周期单元的透过率函数为t unit(x)，周期单元的宽度为d，每个周期单元由两种材质构成，第一种材质(即有机发光体2522)的宽度为a，第二种材质(即像素定义层250)的宽度为d-a，一维像素结构的透过率函数可表示为：

其中，

为卷积符号，comb(x)为一维梳状函数。若采用总宽度为L的平面波照射，则像素结构后的光场分布可表示为：

对(2)式作傅里叶变化可得远场衍射光场分布如下：
Figure PCTCN2020073149-appb-000004
请参阅图4，图4为
Figure PCTCN2020073149-appb-000005
的远场衍射光场分布，可以理解为仅有透过和不透光两部分组件。为了方便理解，忽略常数项，可以看到远场衍射图样由三部分组成：
第一部分：请参阅图5，周期单元的透过率函数的傅里叶变换FT{t unit(x)}，其构成了整个衍射光强的包络，包络形状与周期单元的透过率函数t unit(x)有关(因为t unit(x)宽度为d，所以和间距d也有关)；
第二部分：请参阅图6，梳状函数comb(dx)，其决定了衍射级次之间的间距，其值仅与周期单元间距d有关；
第三部分：请参阅图7，光斑的傅里叶变换sinc(Lx)，其决定了每个衍射光点的大小和形状，其值仅与光斑直径L有关。
根据MATLAB仿真和实验测试数据可以得出衍射级次间距和d成反比关系，随着d的增大，衍射级次间距在逐渐缩小，且当a与d的比例接近a＝0.5d时，±1级衍射光强最强，即
Figure PCTCN2020073149-appb-000006
有最大值。
在MATLAB仿真中，按照λ＝630nm，材质1的折射率n1＝1.79，厚度为d1＝0.3μm，材质2的折射率n1＝1.64，厚度为d2＝1.6μm，材质1的宽度a＝18μm，周期单元尺寸d＝43μm为初始结构，此时透过率函数可表示为:
Figure PCTCN2020073149-appb-000007
下面分别改变a与d的值，观察衍射光强分布。
改变d值，固定矩形像素孔2502的宽度a＝18μm。其中，像素孔2502为矩形，像素孔2502具有第一方向的第一尺寸a，第二方向的第二尺寸b。也可以理解为矩形的像素孔2502的短边宽度为第一尺寸a，长边长度为第二尺寸b。d值为与第一方向相邻两个矩形像素孔2502之间的间距，d值的取值范围为23μm～200μm，根据不同的d值分别得到衍射图样的光强包络和衍射级次分布，具体如图8a-8k所示，其中图8a-8k依次表示为a＝18μm、d＝23μm；a＝18μm、d＝33μm；a＝18μm、d＝43μm；a＝18μm、d＝53μm；a＝18μm、d＝63μm；a＝18μm、d＝73μm；a＝18μm、d＝83μm；a＝18μm、d＝93μm；a＝18μm、d＝103μm；a＝18μm、d＝150μm；a＝18μm、d＝200μm的衍射图样的光强包络和衍射光强。其中，图8a-8k中每个附图中的左侧图像为衍射光强包络，右侧图像为衍射光强。
可以看到，衍射级次间距和d值成反比关系，随着d值的增大，衍射级次间距在逐渐缩小，且当a与d的比例接近a＝0.5d时，±1级衍射光强最强，即
Figure PCTCN2020073149-appb-000008
有最大值。
二、改变a值，固定周期单元的总宽度d＝43μm。a值的取值范围为3μm～38μm，根据不同的a值分别得到衍射图样的光强包络和衍射级次分布，具体如图9a-9h所示，其中图9a-9h依次表示为a＝3μm、d＝43μm；a＝8μm、d＝43μm；a＝13μm、d＝43μm；a＝18μm、d＝43μm；a＝23μm、d＝43μm；a＝28μm、d＝43μm；a＝33μm、d＝43μm；a＝38μm、d＝43μm的衍射图样的光强包络和衍射光强。其中，图9a-9h中每个附图中的左侧图像为衍射光强包络，右侧图像为衍射光强。
可以看到，a值的改变不影响衍射级次间距，同样的，当a与d的比例接近a＝0.5d时，±1级衍射光强最强，即
Figure PCTCN2020073149-appb-000009
有最大值。
由于有机发光层和像素定义层为重影主要原因，故对有机发光层和像素定义层进行仿真(如通过zemax仿真)，观察改变微结构周期单元间隔时衍射级次变化。
将有机发光层和像素定义层的周期单元长度以5um为间隔逐渐由43um增大至78um时，相应的+1、-1、0级光强相对值如表1所示，其中像素孔的第一尺寸a保持不变，第一间距d增大。由于+1、-1级外的更高级次能量始终小于0级能量的10％，而+1、-1级的衍射光强为重影的主要影响因素，因而在本实验 中主要分析+1、-1级与0级，具体可以参阅表1。
表1：
间隔(um) -1级强度、相对位置 0级强度、相对位置 +1级强度、相对位置
43 3195、-0.14 3733、0 3195、0.14
48 2911、-0.13 4487、0 2848、0.13
53 2629、-0.12 5068、0 2629、0.12
58 2323、-0.11 5619、0 2303、0.11
63 2000、-0.10 6496、0 2023、0.10
68 1811、-0.093 6743、0 1750、0.093
73 1656、-0.087 6967、0 1646、0.087
78 1379、-0.08 7504、0 1390、0.08
请参阅图10，图10中示出了有机发光层和像素定义层的周期单元长度变化时能量分布的情况。其中，附图中L1的曲线对应间隔为43um；L2的曲线对应间隔为48um；L3的曲线对应间隔为53um；L4的曲线对应间隔为58um；L5的曲线对应间隔为63um；L6的曲线对应间隔为68um；L7的曲线对应间隔为73um；L8的曲线对应间隔为78um。可以从图中看出，随着有机发光层的有机发光体间隔的增大，衍射级次间的相对位置渐渐向0级(主衍射级)靠拢，反映到所成图像上的现象为重影图像逐渐有向主图像重合的趋势。
同时，随着有机发光体间隔的增大，0级的强度渐渐增强，+-1级的光强渐渐减弱，当周期单元长度为78um、与GFF间隔相同时，主衍射级次光强最大，+1、-1级光强最小。
有机发光体间隔加大后，各衍射级次向中间靠拢且衍射级次间距离变小，+1、-1级光强减弱，但高级次光强渐渐增强。由此可知，第一方向上，有机发光体的第一尺寸a与相邻两个像素孔之间的间距h1的差值越大，衍射就越弱。
请继续参阅图2，在一些实施例中，有机发光体2522的第一尺寸a小于有机发光体2522的第二尺寸b，第二尺寸b与第一间距h1不相等。
其中，有机发光体2522为长条状态，具有短边和长边，短边对应尺寸为第一尺寸a，长边对应尺寸为第二尺寸b。有机发光体2522的第二尺寸b与第一间距h1也不相等。有机发光体2522可以为矩形等形状。
需要说明的是，第一间距h1为像素定义层第一方向相邻两个像素孔之间的间距，有机发光体对应设置在像素孔内，因此，第一间距h1也可以理解为有机发光层第一方向相邻两个有机发光体之间的间距。同理，第二间距h2也可以理解为有机发光层第二方向相邻两个有机发光体之间的间距。
在一些实施例中，有机发光体2522的第一尺寸a小于第一间距h1，第二尺寸b大于第一间距h1。
第一方向上，两个相邻的像素孔2502之间的第一间距h1大于有机发光体2522的第一尺寸a。因为，有机发光体2522的大小一般是固定的，因此，可以增加两个相邻的像素孔2502之间的间距，从而实现第一尺寸a小于第一间距h1。其中，有机发光体2522的第二尺寸b也大于第一间距h1，第一间距h1大于第一尺寸a。可以理解的是，有机发光体2522为长条结构，如矩形等。
在一些实施例中，有机发光体2522的第一尺寸a小于第二尺寸b，第一尺寸a大于第一间距h1。
第一方向上，有机发光体2522的第一尺寸a可以大于两个相邻的像素孔2502之间的第一间距h1，可以改善通过像素结构的光信号的衍射效应。
在一些实施例中，每一像素孔可以为正方形，设置在像素孔内的有机发光体对应也为正方形，有机发光体第一方向的第一尺寸a与第二方向的第二尺寸b相等。第一方向上，有机发光体的第一尺寸a可以大于或小于两个相邻的像素孔的第一间距h1。第二方向上，有机发光体的第二尺寸b可以大于或小于两个相邻的像素孔的第二间距h2，其中，第一间距h1和第二间距h2可以相等也可以不相等，第一间距h1可以大于第二间距h2，第一间距h1也可以小于第二间距h2。可以改善通过像素结构的光信号的衍射效应。
需要说明的是，有机发光体2522的第一尺寸a与第一间距h1的差值越大，改善通过像素结构的光信号的衍射效应的效果越好。第二尺寸b与第二间距h2的差值越大，改善通过像素结构的光信号的衍射效应的效果也越好。
在一些实施例中，每一个像素孔2502可以为矩形，设置在像素孔2502内的有机发光体2522对应也为矩形。第一方向可以理解为阵列的行方向，也可以理解为平行像素孔2502的短边方向，第二方向可以理解为阵列的列方向，也可以理解为平行像素孔2502的长边方向。
请参阅图11，在一些实施例中，像素孔2502及有机发光体2522可以均呈圆角矩形。因为矩形的像素孔2502和有机发光体2522的4个边角为尖角，在光信号透过矩形有机发光体2522后，容易在衍射中形成长条的长虹情况。而圆角矩形的像素孔2502和有机发光体2522，可以减少畸变，可以改善衍射中长条的长虹情况。其中，矩形包括相对设置的两个长边、以及相对设置的两个短边，两个长边通过两个短边连接。圆角矩形可以为四个边角为圆弧形的连接线连接，即，每个长边通过一个圆弧形的连接线与短边连接。圆角矩形也可以为两个长边的两端通过圆弧形的连接线连接，即，两个圆弧形的连接线替换两个短边将两个长边连接。
当然，在其他一些实施例中，配合设置的像素孔2502和有机发光体2522可以设置为椭圆、多边形等其他形状，只要将像素孔2502和有机发光体2522设置成没有锐角或直角的形状即可。例如，有机发光体2522包括相对设置且平行的两个长边，两个长边的一端通过首尾相连的两条连接线连接，其中连接线与长边的夹角、两条连接线之间的夹角均为120度。当然，还可以设置成其他大于90度的角度，还可以设置更多条首尾相连的连接线连接。
需要说明的是，当像素孔2502和有机发光体2522的形状不为矩形时，有机发光体2522包括相对设置的第一侧边和第二侧边、以及将第一侧边和第二侧边连接的且相对设置的第三侧边和第四侧边，有机发光体2522为对称结构，第一侧边和第二侧边的尺寸相等，第三侧边和第四侧边的尺寸相等，第三侧边的尺寸大于第一侧边的尺寸。有机发光体2522在第一方向上的第一尺寸a可以理解为相互平行的第三侧边和第四侧边之间的距离，或者理解为第一侧边的尺寸。有机发光体2522在第二方向上的第二尺寸b可以理解为相互平行的第一侧边和第二侧边之间的距离，或者理解为第三侧边的尺寸。
请参阅图12，在一些实施例中，显示装置包括层叠设置的第一基板220、阳极金属层240、像素定义层250、公共电极层260和第二基板280。像素定义层250设置在阳极金属层240和公共电极层260之间。阳极金属层240、公共电极层260配合驱动有机发光层252，以使有机发光层252显示各种图像。摄像头模组160可以透过显示装置140的任意位置采集图像，即可以获取透过显示装置140的任意位置获取光信号，并根据光信号形成图像。
其中，第一基板220和第二基板280均可以为无色透明的基板，具体可以采用玻璃、树脂等材料，第一基板220和第二基板280还可以为柔性基板，并且显示装置整体为柔性显示装置。
其中，阳极金属层240包括第一阳极金属层242、平坦化层244和第二阳极金属层246。第一阳极金 属层242设置在平坦化层244和像素定义层250之间，第二阳极金属层246设置在平坦化层244和第一基板220之间。
显示装置140还包括薄膜晶体管248，薄膜晶体管248分别连接第一阳极金属层242、第二阳极金属层246和有机发光层252，第一阳极金属层242、第二阳极金属层246和有机发光层252分别连接薄膜晶体管248的不同极。
在一些实施例中，第一阳极金属层242设置在平坦化层244和有机发光层252之间，第一阳极金属层242的材料为纳米银。
第一阳极金属层242包括多条第一导电线，第一导电线沿第一方向延伸，每条第一导电线对应两个像素孔2502之间的部分，用纳米银制成的第一阳极金属层242。其中，用纳米银制成的每条第一导电线在满足阻抗特性的情况下，可以制作的更窄或更薄或更窄且更薄，第一方向上，两个像素孔2502之间的间距h1可以做的更小，使第一间距h1小于第一尺寸a。
在一些实施例中，显示装置还包括薄膜230，薄膜230设置在第一基板220和阳极金属层240之间。薄膜230可以采用SiNx或SiO2制成。
在一些实施例中，显示装置还包括光提取材料层(capping layer，CPL)270。光提取材料层270设置在第二基板280和公共电极层260之间。
需要说明的是，显示装置可以包括薄膜230和光提取材料层270，也可以不包括薄膜230和/或光提取材料层270。
请参阅图13，在一些实施例中，显示装置还包括填充层290，填充层290设置于公共电极层260背离像素定义层250的一侧，填充层290包括多个填充体2902，每一个填充体2902相对一个像素孔2502设置，像素定义层250与填充层290的折射率之差小于像素定义层250与真空的折射率之差。
需要说明的是，光信号透过显示装置140时，光信号透过对应像素孔2502的显示装置第一区域具有第一光程，光信号透过对应非像素孔的显示装置第二区域具有第二光程，两者具有光程差，公共电极层260覆盖于有机发光体2522和像素定义层250，公共电极层260各处的厚度大致相等，公共电极层260对光程差没有影响或影响很小。因为像素定义层250和有机发光体2522的光学参数不同，对应非像素孔的像素定义层250、以及对应像素孔2502区域的有机发光体2522对光程差影响较大。另外，相关技术中，因为显示装置的制程原因，显示装置内相对像素孔2502区域会有一个间隙，该间隙位于公共电极层260背离像素孔2502一侧，因为相对像素定义层250没有间隙，所以该间隙对光程差影响也很大。因为间隙内的真空与像素定义层250的光线参数相差非常大，此时，本申请实施例对应该间隙设置一填充体2902，并且像素定义层250与填充体2902的折射率之差小于像素定义层250与真空的折射率之差，可以改善第一光程和第二光程的光程差，从而改善摄像头160透过显示装置140的成像质量。
具体的，在一些实施例中，公共电极层260具有多个第二凹槽2608，多个第二凹槽2608的开口朝向第二基板280，每一个第二凹槽2608相对一个像素孔2502设置。对应多个第二凹槽2608，光提取材料层270具有多个第三凹槽2709，多个第三凹槽2709的开口朝向第二基板280，每一个第三凹槽2709正对一个像素孔2502，每一个填充体2902设置于一个第三凹槽2709内。
对应公共电极层260的第二凹槽2608，光提取材料层270具有第三凹槽2709，填充体2902设置于第三凹槽2709内，对原显示装置140的结构影响较小。
在一些实施例中，显示装置140对应像素孔2502所在位置具有垂直于第一基板220方向的第一光程，显示装置140对应像素孔2502以外的位置具有垂直于第一基板220方向的第二光程，第一光程等于第二光程。
其中，第一光程可以理解为光信号以垂直于第一基板220方向，从对应像素孔2502所在位置穿过显示装置140的光程。第一光程具体可以为第二基板280、光提取材料层270、填充层290、公共电极层260、有机发光层252、阳极金属层240和第一基板220中各层对应的厚度和折射率的乘积之和。
第二光程可以理解为光信号以垂直于第一基板220方向，从对应非像素孔所在位置穿过显示装置140的光程。第一光程具体可以为第二基板280、光提取材料层270、公共电极层260、像素定义层250、阳极金属层240和第一基板220中各层对应的厚度和折射率的乘积之和。
其中，因为第二基板280、光提取材料层270、公共电极层260、阳极金属层240和第一基板220中每层都覆盖整层，且每层各个位置的厚度大致相等，因此第二基板280、光提取材料层270、公共电极层260、阳极金属层240和第一基板220对应第一光程和第二光程的光程差可以忽略。
需要说明的是，第一光程等于第二光程可以理解为第一光程与第二光程大致相等。
在一些实施例中，填充层还包括连接体，连接体覆盖于公共电极层，并与多个填充体连接。
填充体填充在第三凹槽内，连接体则可以覆盖整层，即连接体覆盖整个公共电极层和填充体。其中，填充体若刚好填充满第三凹槽，则连接体相对的两个面平行。
在一些实施例中，每个填充体可以设置于一个第二凹槽内，填充层的多个填充体对应设置于公共电极层的多个第二凹槽内，光提取材料层则覆盖于填充层和公共电极层。当填充体填充满第二凹槽时，光提取材料层可以设置平铺于公共电极层和填充层。在其他一些实施例中，填充体朝向光提取材料层的表面可以高于或低于公共电极层，即，填充体可以不填满第二凹槽，或高出第二凹槽。
请参阅图14，在一些实施例中，显示装置还包括遮光块272，遮光块272可以为黑色或深色的材料，遮光块272可以用来遮挡进入显示装置240的光线。遮光块272对应薄膜晶体管248设置，遮光块272可以设置在有机发光层252和第二基板280之间，每一个遮光块272至少部分与一个薄膜晶体管248相对设置。例如，薄膜晶体管248在第一基板220上的投影可以位于遮光块272在第一基板220的投影内。如此，可以防止光线进入显示装置后被薄膜晶体管248反射、折射等，从而导致杂光干扰成像。
在一些实施例中，遮光块272可以设置在光提取材料层270，如光提取材料层270对应于薄膜晶体管248的位置设有通孔或凹槽，遮光块272对应设置在通孔或凹槽内，凹槽的开口可以朝向第二基板280，也可以朝向公共电极层260。
在一种实施方式中，第二基板280对应薄膜晶体管248的位置可以设置凹槽，遮光块272对应设置在第二基板280的凹槽内，第二基板280的凹槽的开口朝向公共电极层260。在一种实施方式中，遮光块272还可以设置在有机发光层252和公共电极层260之间的间隙内。
请参阅图15，遮光块272还可以设置在设置了填充层290的显示装置上，具体结构可以采用上述实施例的结构，在此不再赘述。需要说明的是，在其他一些实施例中，遮光块还可以设置在填充层290内。
在一些实施例中，请参阅图16，显示装置240可以包括透光区132和主体区134，透光区132的面积小于主体区134的面积，透光区132的透光率大于主体区134的透光率，摄像头模组160与透光区132相对设置。
透光区132与第一驱动模块1444连接，主体区134与第二驱动模块1442连接，第一驱动模块1444驱动显示装置240的透光区132，第二驱动模块1442驱动显示装置240的主体区134。其中，第一驱动模块1442和第二驱动模块1444可以配合驱动，使透光区132和主体区134共同显示同一图像。如透光区132显示图像的一部分，主体区134显示图像剩下的部分。当摄像头模组160需要获取图像时，第一驱动模块1444驱动透光区132关闭显示，第二驱动模块1442可以继续驱动主体区134显示图像，摄像头模组160通过关闭显示的透光区132获取外界的光信号，并根据光信号得到图像。
在一些实施例中，请参阅图17，并结合图1和图2，像素定义层250包括第一部分254和第二部分256。第一部分254对应透光区，第二部分256对应主体区。第一部分254的面积小于第二部分256的面积，第二部分256也包括呈阵列排布多个有机发光体2522，第一部分254的透光率大于第二部分的透光率。摄像头模组160可以获取透过显示装置140第一部分254获取光信号，并根据光信号形成图像。
在一些实施例中，第一部分254位于像素定义层250的端部。具体的，第一部分254可以位于像素定义层250的顶端或底端或侧边，如像素定义层250为矩形，第二部分256为具有一个缺口的矩形，第一部分254设置在该缺口内，该缺口可以设置在第二部分256的顶边或底边或侧边。当然，第一部分254也可以设置在像素定义层250的中间，也可以理解为第二部分256具有一个厚度方向贯穿第二部分256的通孔，第一部分254设置在该通孔内。
对应的，摄像头模组160对应第一部分设置，摄像头模组160可以获取透过显示装置140的第一部分254获取光信号，对应第一部分254的显示装置140的透光率大于对应第二部分的显示装置12的透光率。具体的，对应第一部分254的有机发光体2522的分布密度更小，即小于对应第二部分256的有机发光体2522的分布密度。第一部分254对应的有机发光体2522的分布密度更小，与有机发光体2522一一对应的不透光的薄膜晶体管248的分布密度也更小，从而提高了第一部分对应的显示装置140的透光率。
在一些实施例中，第一部分254的有机发光体2522的分布密度小于第二部分256的有机发光体2522的分布密度。也可以理解为，第一部分254相邻的两个像素孔2502的间距大于第二部分256相邻的两个像素孔2502的间距，像素定义层250的透光率大于有机发光体2522的透光率，第一部分254的有机发光层252的占比更小，从而使第一部分254的透光率大于第二部分256的透光率。另外，每一个有机发光体2522对应设置一个薄膜晶体管248，薄膜晶体管248是不透光的，第一部分254的有机发光体2522的分布密度更小，对应的薄膜晶体管248的分布密度也更小，从而使第一部分254的透光率大于第二部分256的透光率。
其中，透光区和主体区主要在像素定义层不同。透光区和主体区可以共用同一块第一基板、第二基板等。
需要说明的是，第一部分254对应的阳极金属层240可以用高透光的材料制成，如ITO、纳米银等。第二部分256对应的阳极金属层240可以用高透光的材料制成，也可以用低透光或不透光的材料制成。
在一些实施例中，请参阅图18，显示装置140包括第一显示面板1422和第二显示面板1424，第一显示面板1422设置有缺口110，缺口110在第一显示面板1422的厚度方向上贯穿第一显示面板1422，第一显示面板1422为正常显示的显示面板142。第二显示面板1424设置在缺口110内，第二显示面板1424对应显示装置240的透光区，第一显示面板1422对应显示装置240的主体区。电子设备100的摄像头模组160设置在壳体和第二显示面板1424之间，摄像头模组160获取透过透光区的光信号，并根据获取的光信号得到图像。
第一显示面板1422和第二显示面板1424为两个独立的显示面板，先分别制造好第一显示面板1422和第二显示面板1424，然后再将第二显示面板1424放置在第一显示面板1422的缺口110内。
