具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
相关技术中，为了提高显示面板的屏占比，可以将显示装置的前置摄像头设置在显示面板的显示区域。其中，显示面板的显示区域包括：沿远离衬底基板的方向依次层叠的阳极层，发光层以及阴极层。该摄像头设置在阳极层远离发光层的一侧。
但是，由于该阴极层会对光透过率造成影响，因此设置在显示面板的显示区域的前置摄像头的成像效果较差。
图1是本申请实施例提供的一种掩膜组件的结构示意图。参考图1可以看出，该掩膜组件10可以包括：环形的掩膜框架101，支撑结构102，以及掩膜结构103。
图2是图1所示的掩膜组件的爆炸示意图。参考图2，该支撑结构102可以位于掩膜框架101的一侧，该支撑结构102可以与掩膜框架101固定连接，且该支撑结构102可以具有开口102a，该开口102a可以用于形成显示面板中除阴极图案之外的其他膜层。掩膜结构103可以位于掩膜框架101的一侧，且该掩膜结构103可以与掩膜框架101固定连接。图2中掩膜结构103位于支撑结构102远离掩膜框架101的一侧。
图3是本申请实施例提供的一种掩膜结构的结构示意图。该掩膜结构103可以包括：条状的掩膜主体1031，以及与开口102a对应的片状的掩膜件1032。该掩膜件1032可以与掩膜主体1031的侧边固定连接，且该掩膜件1032上具有多个第一通孔1032a。该掩膜主体1031在掩膜框架101的承载面上的正投影，可以与开口102a在承载面上的正投影不重叠，避免该掩膜主体1031对形成显示面板的膜层造成影响。并且，掩膜件1032在承载面上的正投影，可以与开口102a在承载面上的正投影重叠，由此可以使得掩膜件1032中的多个第一通孔1032a形成多个具有间隙的图案。
若该掩膜组件10用于制备显示面板中各个子像素的阴极层，则掩膜件1032中的每个第一通孔1032a可以用于形成显示面板的一个阴极图案。由于多个第一通孔1032a之间具有间隙，因此采用该多个第一通孔制备得到的多个阴极图案之间也具有间隙。也即是采用该掩膜组件制备得到的阴极层并不是整层覆盖，光透过率较高，摄像头的成像效果较好。
并且，由于支撑结构102和掩膜结构103为单独的两个结构，且支撑结构102上设置开口102a，掩膜结构103上设置多个第一通孔1032a。因此能够保证在将支撑结构102与掩膜框架101连接时，该支撑结构102中的开口102a的位置精度，且能够保证在将掩膜结构103与掩膜框架101连接时，该掩膜结构103中多个第一通孔1032a的位置精度。由此降低了掩膜组件10的制造难度，提高采用该掩膜组件10制备得到的显示面板的良率。
综上所述，本申请实施例提供了一种掩膜组件，该掩膜组件中掩膜结构的第一通孔可以用于形成显示面板的阴极图案，支撑结构的开口可以用于形成显 示面板中除该阴极图案之外的其他膜层。由于通过该多个第一通孔形成的多个阴极图案之间具有间隙，因此采用该掩膜组件制备得到的显示面板的光透过率较高，摄像头的成像效果较好。
可选的，该掩膜结构103中的掩膜主体1031和掩膜件1032可以为一体结构，可以避免掩膜主体1031和掩膜件1031相对移动，保证掩膜结构103的质量。并且，该掩膜框架101，支撑结构102，以及掩膜结构103可以均采用因瓦合金(invar)材料制备得到。
在本申请实施例中，掩膜件1032上设置的多个第一通孔1032a中的每个第一通孔1032a的形状可以为规则图形或不规则图形。其中，规则图形可以包括：多边形，圆形或椭圆形等，其中多边形可以包括凸多边形和凹多边形。不规则图形可以是由曲线和直线构成的图形。也即是，本申请实施例对该第一通孔1032a的形状不做限定。
参考图3，每个第一通孔1032a的形状可以为多边形，且该多边形可以为矩形。可选的，每个第一通孔1032a垂直的两条边中每一条边的长度范围可以为0.01mm(毫米)至0.3mm。

示例的，由于该第五凹槽101e连接的是掩膜主体1031的第一连接部10311，因此该第五凹槽101e的深度可以等于该第一连接部10311沿垂直于承载面的方向的长度。并且，由于该第六凹槽101f连接的是掩膜主体1031的第二连接部10312，因此该第六凹槽101f的深度可以等于该第二连接部10312沿垂直于承载面的方向的长度。
结合图2和图5可以看出，该支撑结构102远离掩膜框架101的一侧可以具有条形的第七凹槽102b，该掩膜结构103的支撑部10313可以位于第七凹槽102b内。由此可以避免该掩膜结构103与支撑结构102之间相对移动，保证掩膜结构103的位置精度。
在本申请实施例中，该第七凹槽102b的深度d1可以为支撑部10313沿垂直于承载面的方向的长度d2的0.9倍至1.1倍。示例的，参考图6，该第七凹槽102b的深度d1与掩膜结构103的支撑部10313沿垂直于承载面的方向的长度d2相等。由此可以使得支撑部10313远离掩膜框架101的一面与支撑结构102的一面共面，掩膜组件10的平整性较好。
可选的，第一连接部10311沿垂直于承载面的方向的长度，第二连接部10312沿垂直于承载面的方向的长度，以及支撑部10313沿垂直于承载面的方向的长度可以均相等。因此为了保证掩膜组件10的平整性，可以使得该第五凹槽101e的深度，该第六凹槽101f的深度，以及该第七凹槽102b的深度均相等。
由于掩膜框架101中的第五凹槽101e的深度和第六凹槽101f的深度均等于 支撑结构102中第七凹槽102b的深度，且该第七凹槽102b的深度小于该支撑结构102沿垂直于掩膜框架101的承载面的方向的长度。因此该第一凹槽101a的深度，该第二凹槽101b的深度，该第三凹槽101c的深度，以及第四凹槽101d的深度均大于第五凹槽101e的深度和第六凹槽101f的深度。

其中，该第一侧和第二侧可以为掩膜主体1031相对的两侧，且第一侧的延伸方向和第二侧的延伸方向可以均平行于掩膜主体1031的延伸方向G1。
示例的，参考图1，支撑结构102可以具有10个开口102a，该10个开口102a对称分布在一个掩膜结构103的两侧。即该掩膜结构103的每侧具有5个开口102a。结合图1和图3，该掩膜结构103可以包括：10个掩膜件1032，每个掩膜件1032在掩膜框架101的承载面上的正投影，与一个开口102a在承载面上的正投影重叠。
其中，采用本申请实施例提供的掩膜组件10制备得到的多个显示面板中位于掩膜结构103的两侧的显示面板的排布方向相反。并且，每个显示面板中用于设置摄像头的区域均靠近掩膜结构103的一侧。
作为另一种可选的实现方式，参考图7和图8，该支撑结构102可以具有多个开口102a，且该多个开口102a可以位于掩膜结构103的一侧。
示例的，参考图7和图8，掩膜组件10可以包括两个掩膜结构103(第一个掩膜结构103a和第二个掩膜结构103b)。支撑结构102可以具有10个开口102a，该10个开口102a中的5个开口位于第一个掩膜结构103a的一侧，该10个开口102a中的另外5个开口位于第二个掩膜结构103b的一侧。

其中，采用本申请实施例提供的掩膜组件10制备得到的多个显示面板的排布方向相同。并且，每个显示面板中用于设置摄像头的区域均靠近用于制备该显示面板的掩膜结构103的一侧。
图10是图7所示的掩膜组件的爆炸示意图。参考图10可以看出，该掩膜组件10包括两个掩膜结构103(第一掩膜结构103a和第二掩膜结构103b)。相应的，该支撑结构102上可以具有两个条形的第七凹槽(102b1和102b2)，掩膜框架101上可以具有两个第五凹槽101e和两个第六凹槽101f。
其中，该第一掩膜结构103a可以位于对应的第七凹槽102b1内，且该第一掩膜结构103a可以与对应的一个第五凹槽101e和对应的一个第六凹槽102f连接。该第二掩膜结构103b可以位于对应的第七凹槽102b2内，且该第二掩膜结构103b可以与对应的一个第五凹槽102e和对应的一个第六凹槽102f连接。
在本申请实施例中，参考图5，该支撑结构102可以为片状结构，该片状结构上具有多个开口102a。或者，参考图11，该支撑结构102可以包括：多个条状结构1021，该多个条状结构1021围成多个开口102a。
图12是本申请实施例提供的又一种掩膜结构的结构示意图。图13是本申请实施例提供的一种掩膜结构和支撑结构的截面图。结合图12和图13，该支撑部10313可以具有多个第二通孔10313a。该多个第二通孔10313a能够可以降低该支撑部10313的刚性，支撑部10313的拉伸性能较好。从而可以在采用张网的方式将掩膜结构103与掩膜框架101连接时，对掩膜主体1031施加一定的拉力，以调节掩膜主体1031和掩膜框架101的位置关系，进而调节掩膜件1032在框架主体1011的承载面上的位置，保证掩膜件1032中第一通孔1032a的位置精度。
由于该掩膜件1032中第一通孔1032a的位置精度较高，因此采用该掩膜组件10制备得到的显示面板中膜层的位置精度也较高，显示面板的良率较高。
在本申请实施例中，第二通孔10313a中的每个第二通孔10313a的形状也可以为多边形，圆形或椭圆形。参考图12，每个第二通孔10313a的形状也可以为多边形，且该多边形可以为矩形。可选的，每个第二通孔10313a垂直的两条边 中每一条边的长度范围可以为0.01mm至0.3mm。
可选的，该第二通孔10313a形状可以与第一通孔10313a的形状相同。当然，该第二通孔10313a形状也可以与第一通孔10313a的形状不同。并且，该第二通孔10313a尺寸可以与第一通孔10313a的尺寸相同。当然，该第二通孔10313a尺寸也可以与第一通孔10313a的尺寸不同。
综上所述，本申请实施例提供了一种掩膜组件，该掩膜组件中掩膜结构的第一通孔可以用于形成显示面板的阴极图案，支撑结构的开口可以用于形成显示面板中除该阴极图案之外的其他膜层。由于通过该多个第一通孔形成的多个阴极图案之间具有间隙，因此采用该掩膜组件制备得到的显示面板的光透过率较高，摄像头的成像效果较好。
图14是本申请实施例提供的一种掩膜组件的制造方法的流程图。参考图14可以看出，该方法可以包括：
步骤201、提供环形的掩膜框架，支撑结构，以及掩膜结构。
在本申请实施例中，支撑结构102可以具有开口102a。该开口102a可以用于形成显示面板中的膜层。掩膜结构103可以包括：条状的掩膜主体1031，以及与开口102a对应的片状的掩膜件1032。该掩膜件1032可以与掩膜主体1031的侧边固定连接，且该掩膜件1032可以具有多个第一通孔1032a。
其中，每个第一通孔1032a可以用于形成显示面板的一个阴极图案。由于多个第一通孔1032a之间具有间隙，因此制备得到的显示面板中的多个阴极图案之间也具有间隙，光线可以从该多个阴极图案之间的间隙透过，光透过率较好，摄像头的成像效果较好。
可选的，该掩膜主体1031和该掩膜件1032可以为一体结构。
步骤202、将支撑结构设置在掩膜框架的一侧，并将该支撑结构与掩膜框架焊接。
在本申请实施例中，可以先将支撑结构102设置在掩膜框架101的一侧，之后采用张网机将支撑结构102拉伸至合适位置，并将该支撑结构102与掩膜框架101焊接，保证支撑结构102中的开口102a的位置精度。
步骤203、将掩膜结构设置在掩膜框架的一侧，并将掩膜结构与掩膜框架焊接。
在本申请实施例中，可以先将掩膜结构103设置在掩膜框架101的一侧， 例如将掩膜结构103设置在支撑结构102远离掩膜框架101的一侧。之后采用张网机将掩膜结构103拉伸至合适位置，且为了避免掩膜结构103中的第一通孔1032a的位置偏移，可以对该掩膜结构103施加一定的拉力，然后再将该掩膜结构103与掩膜框架101焊接。
步骤204、将掩膜结构与支撑结构焊接。
在本申请实施例中，为了进一步避免掩膜结构103中的第一通孔1032a的位置偏移，还可以将掩膜结构103掩膜主体1031的支撑部10313与支撑结构102焊接。
在本申请实施例中，在将掩膜结构103与掩膜框架101和支撑结构102焊接完成后，还可以对该掩膜结构103进行切割，以避免掩膜结构103的边界超出掩膜框架101的边界。并且，在将掩膜结构103与掩膜框架101和支撑结构102焊接完成后，可以检测该掩膜结构103中第一通孔1032a的位置和尺寸是否满足使用要求。在确定满足要求时，即可以使得制造得到的掩膜组件10投入使用，进而制备显示面板。
综上所述，本申请实施例提供了一种掩膜组件的制造方法，该方法制作得到的掩膜组件中掩膜结构的第一通孔可以用于形成显示面板的阴极图案，支撑结构的开口可以用于形成显示面板中除该阴极图案之外的其他膜层。由于通过该多个第一通孔形成的多个阴极图案之间具有间隙，因此采用该掩膜组件制备得到的显示面板的光透过率较高，摄像头的成像效果较好。
图15是本申请实施例提供的一种显示面板的结构示意图。该显示面板可以由上述实施例提供的掩膜组件10制备得到。参考图15可以看出，该显示面板30可以包括：衬底基板301，第一阳极层302，第一发光层303，第一阴极层304，第二阳极层305，第二发光层306以及第二阴极层307。

综上所述，本申请实施例提供了一种显示面板，该显示面板包括的第二阴极层可以设置在衬底基板的第二显示区域。由于该第二阴极层包括的多个阴极图案间隔设置，因此相对于整层覆盖第二显示区域的阴极层，能够有效减小对光透过率的影响，位于该第二显示区域的摄像头的成像效果较好。
在本申请实施例中，第一阳极层302，第一发光层303，以及第一阴极层304能够划分为多个第一子像素。该第二阳极层305，第二发光层306，以及第二阴极层307能够划分为多个第二子像素。

示例的，参考图17，每个阴极图案3071在衬底基板101上的正投影可以覆盖三个第二子像素的发光区域在衬底基板101上的正投影。其中，该三个第二子像素可以包括：红色(red，R)子像素，绿色(green，G)子像素，以及蓝色(blue，B)子像素。
图18是本申请实施例提供的另一种显示面板的结构示意图。参考图18可以看出，该显示面板30还可以包括：位于第一显示区域301a的第一空穴注入 层308，第一空穴传输层309，第一电子传输层310和第一电子注入层311，以及位于第二显示区域301b的第二空穴注入层312，第二空穴传输层313，第二电子传输层314和第二电子注入层315。
其中，该第一阳极层302，第一空穴注入层308，第一空穴传输层309，第一发光层303，第一电子传输层310，第一电子注入层311，以及第一阴极层304沿远离衬底基板301的方向依次层叠。该第二阳极层305，第二空穴注入层312，第二空穴传输层313，第二发光层306，第二电子传输层314，第二电子注入层315以及第二阴极层307沿远离衬底基板301的方向依次层叠。
可选的，该第一阳极层302，第一发光层303，第二阳极层305，第二发光层306，第一空穴注入层308，第一电子注入层311，第二空穴注入层312，以及第二电子注入层315均可以采用精细金属掩膜(fine metal mask，FMM)制备得到。
该第一空穴传输层309，第一电子传输层310，第二空穴传输层313，以及第二电子传输层314可以采用开放式掩膜板制备得到。也即是，该第一空穴传输层309，第一电子传输层310，第二空穴传输层313，以及第二电子传输层314可以均为板状结构。
或者，该第一空穴传输层309，第一电子传输层310，第二空穴传输层313，以及第二电子传输层314可以采用本申请实施例提供的上述掩膜组件10制备得到。其中，该第一空穴传输层309和第一电子传输层310可以均呈板状结构。该第二空穴传输层313可以包括：间隔设置的多个空穴传输图案3131。该第二电子传输层314可以包括：间隔设置的多个电子传输图案3141。
该掩膜组件10中支撑结构102的开口102a可以形成该第一空穴传输层309和第一电子传输层310，该掩膜组件10中掩膜结构103中的多个第一通孔1032a中的每个第一通孔1032a可以用于形成一个空穴传输图案3131或一个电子传输图案3141。
可选的，用于形成显示面板30中的空穴传输图案3131的掩膜组件10中的第一通孔，以及用于形成电子传输图案3141的掩膜组件10中的第一通孔的形状和尺寸可以相同。
并且，用于形成显示面板30中的空穴传输图案3131的掩膜组件10中的第一通孔的形状，可以与用于形成显示面板30中的阴极图案3071的掩膜组件10中的第一通孔的形状相同。用于形成显示面板30中的空穴传输图案3131的掩 膜组件10中的第一通孔的尺寸，小于用于形成显示面板30中的阴极图案3071的掩膜组件10中的第一通孔的尺寸。
也即是，空穴传输图案3131的形状，电子传输图案3141的形状以及阴极图案的形状可以相同。并且，空穴传输图案3131的尺寸和电子传输图案3141的尺寸可以相同，空穴传输图案3131的尺寸小于阴极图案3071的尺寸。由此阴极图案3071与空穴传输图案3131和电子传输图案3141可以存在不重叠区域，从而可以使得阴极图案3071可以通过过孔与位于空穴传输图案3131靠近衬底基板301的一侧的阴极信号线连接，以便该阴极信号线为阴极图案3071提供阴极信号。
当然，空穴传输图案3131的形状和电子传输图案3141的形状，与阴极图案3071的形状也可以不同，本申请实施例对此不做限定。
可选的，由于空穴传输图案3131和电子传输图案3141的形状和尺寸可以相同，因此该空穴传输图案3131和电子传输图案3141可以采用同一个掩膜组件10制备，或者可以采用两个掩膜组件10制备。
在本申请实施例中，该第二显示区域301b的形状可以为矩形，且该矩形垂直的两条边中的一条边的长度范围可以为2mm至10mm，另一条边的长度范围可以为2mm至15mm。
示例的，该第二显示区域301b沿像素行方向H1的长度m1可以为3.21mm，即m1＝3.21mm。该第二显示区域301b沿像素列方向H2的长度m2可以为3.04mm，即m2＝3.04mm。
当然，该第二显示区域301b的形状还可以为其他形状，例如，参考图19，该第二显示区域301b的形状为梯形。本申请实施例对该第二显示区域301b的形状不做限定。
综上所述，本申请实施例提供了一种显示面板，该显示面板包括的第二阴极层可以设置在衬底基板的第二显示区域。由于该第二阴极层包括的多个阴极图案间隔设置，因此相对于整层覆盖第二显示区域的阴极层，能够有效减小对光透过率的影响，位于该第二显示区域的摄像头的成像效果较好。
图20是本申请实施例提供的一种显示装置的结构示意图。参考图20可以看出，该显示装置00可以包括：图像传感器40以及如上述实施例提供的显示面板30。该图像传感器40可以位于显示面板30中衬底基板301远离第二阳极 层305的一侧，且位于衬底基板301的第二显示区域301b。其中，该图像传感器40可以为显示装置00的前置摄像头，用于拍摄图像。
