具体实施方式
下面将结合本公开的实施例中的附图，对本公开的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公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开的保护的范围。
显示装置可以用作手机、平板电脑、个人数字助理(personal digital assistant，PDA)、车载电脑等，本公开的实施例对显示装置的具体用途不做特殊限制。
在本公开的一些实施例中，如图1所示，该显示装置包括框架1、显示面板2、电路板3、盖板4、以及其他电子配件。显示面板2包括显示基板21和封装层22。
本公开的实施例提供一种显示基板21，该显示基板21可以用作上述显示装置中的显示基板21。当然，该显示基板21还可以用于其他显示装置，本公开的实施例对此不作特殊限定。
如图2所示，该显示基板21具有子像素区域101和子像素区域101 之间或围绕子像素区域101的非子像素区域102；显示基板21包括：发光器件层，发光器件层包括第一电极层，第一电极层包括多个相互电连接的第一电极123；以及部分相邻第一电极123之间的镂空区域103，镂空区域103位于非子像素区域102内。
在一些实施例中，如图3-图5所示，显示基板21还包括衬底10和设置于衬底10上的薄膜晶体管11。发光器件层12设置于薄膜晶体管11背离衬底10一侧。
在一些实施例中，如图3-图5所示，包括所述显示基板21的显示面板2例如可以是有机发光二极管(Organic Light-Emitting Diode，简称OLED)显示面板，或量子点电致(Quantum Dot Light Emitting Diodes，简称QLED)显示面板。
在一些实施例中，发光器件层12包括发光功能层122。若显示面板2为OLED显示面板，则发光功能层122为有机发光功能层；若显示面板2为QLED显示面板，则发光功能层122为量子点发光功能层。
在一些实施例中，第一电极123为阴极，即，发光器件层12共阴极；或者，第一电极123为阳极，即发光器件层12为共阳极。
在一些实施例中，以OLED显示面板为例，显示面板2例如可以是顶发光显示面板或底发光显示面板中的任意一种。图3-图5仅示出顶发显示面板。
在一些实施中，第一电极123可以覆盖一个子像素区域101，也可以覆盖多个子像素区域101。
在一些实施例中，根据实际需求，子像素区域101可以是任意形状。
示例的，如图2所示，子像素区域101的形状为六边形；如图10所示，子像素区域101的形状为矩形。
在一些实施例中，第一电极123与子像素区域101一一对应，第一电极123的形状和与其对应的子像素区域101的形状可以相同或不同，只要第一电极123完全覆盖与其对应的子像素区域101即可。
示例的，如图2所示，第一电极123和与其对应的子像素区域101 的形状均为六边形。
在一些实施例中，显示基板21具有显示区，显示区中除子像素区域101以外的区域即为非子像素区域102。
在一些实施例中，所有第一电极123均电连接，且部分相邻的第一电极123之间具有镂空区域103。即，除用于构成镂空区域103的相邻的第一电极123，其他相邻的第一电极123之间无镂空区域103；即，其他相邻的第一电极123之间直接接触。
在一些实施例中，不对第一电极123的尺寸进行限定，只要所有第一电极123电连接、且部分相邻的第一电极123之间具有镂空区域103即可。
在一些实施例中，如图2所示，相邻且直接接触的第一电极123在衬底10上的正投影无交叠；或者，如图6所示，相邻且直接接触的第一电极123在衬底10上的正投影部分交叠。
在一些实施例中，如图6所示，相邻且直接接触的第一电极123在衬底10上的正投影的交叠部分位于非子像素区域102。
本公开的实施例提供一种显示基板21，显示基板21包括发光器件层12，发光器件层12包括第一电极层，第一电极层包括多个电连接的第一电极123，部分相邻的第一电极123之间具有镂空区域103，镂空区域103在非子像素区域102内。这样一来，可大大提高显示基板21中镂空区域103的部分的光透过率，当所述显示基板21应用于显示装置时，可在背离发光器件层12的出光侧一侧设置接收光信号的采集部14，以使显示装置实现更多功能。
在一些实施例中，发光器件层12还包括与第一电极层层叠设置的第二电极层，第二电极层包括多个间隔设置的第二电极121；至少部分相邻第二电极121之间的区域与镂空区域103重叠。
在一些实施例中，在第一电极123为阴极的情况下，第二电极121为阳极；在第一电极123为阳极的情况下，第二电极121为阴极。
在一些实施例中，第二电极121与子像素区域101一一对应。在第一电极123也与子像素区域101一一对应的情况下，第二电极121的形 状和尺寸可以与第一电极123的形状和尺寸相同或不同。
在一些实施例中，第二电极121恰好覆盖与其对应的子像素区域101；或者，如图2所示，第二电极121位于与其对应的子像素区域101，且第二电极121的边沿超出与其对应的子像区域101。
本公开的实施例中，通过使至少部分相邻第二电极121之间的区域与镂空区域103重叠，这样一来，可以将接收光信号的采集部14设置在相邻第二电极121之间的区域与镂空区域103的重叠区域，从而使采集部14的任意位置均可接收光信号，提高采集部14的检测效率。
在一些实施例中，如图2、图6和图7所示，所述第一电极123与所述子像素区域101一一对应；多个所述子像素区域101包括多行子像素区域101，所述多行子像素区域101包括多个第一颜色子像素区域、多个第二颜色子像素区域、以及多个第三颜色子像素区域；奇数行或偶数行子像素区域中的每一行子像素区域包括所述第一颜色子像素区域和所述第二颜色子像素区域；并且偶数行或奇数行子像素区域中的每一行子像素区域包括所述第三颜色子像素区域，与偶数行或奇数行子像素区域中的每一行子像素区域中的所述第三颜色子像素区域对应的所述第一电极123与所述镂空区域103沿行方向交替排列。根据一些示例，沿行方向，所述第三颜色子像素区域与所述第一颜色子像素区域和所述第二颜色子像素区域均错开设置，并且与所述第三颜色子像素区域对应的所述第一电极123和与所述第一颜色子像素区域和所述第二颜色子像素区域对应的所述第一电极123均错开设置；奇数行或偶数行子像素区域中的每一行子像素区域中的所述第一颜色子像素区域和所述第二颜色子像素区域对应的所述第一电极123中的相邻的第一电极123直接接触，并与在行方向位于所述相邻的第一电极123之间、在列方向与所述相邻的第一电极123相邻且与所述第三颜色子像素区域对应的所述第一电极123直接接触。
在一些实施例中，如图2、图6和图7所示，第一电极123与子像素区域101一一对应；多个子像素区域101包括多个第一颜色子像素区域、多个第二颜色子像素区域、以及多个第三颜色子像素区域；第一颜色子像素区域和第二颜色子像素区域位于同一行且交替排布，第三颜色 子像素区域位于第一颜色子像素区域的相邻行；沿行方向，第三颜色子像素区域与第一颜色子像素区域和第二颜色子像素区域均错开设置；沿行方向，与第一颜色子像素区域对应的第一电极123和与第二颜色子像素区域对应的第一电极123直接接触；沿列方向，与第三颜色子像素区域对应的第一电极123，和与其错开且与第一颜色子像素和第二颜色子像素对应的第一电极123直接接触；镂空区域103位于与第三颜色子像素区域对应的、沿行方向排布的相邻第一电极123之间。
即，镂空区域103由与相邻的第三颜色子像素区域对应的第一电极123、以及与位于相邻第三颜色子像素区域之间的第一颜色子像素区域和/或第二颜色子像素区域对应的第一电极123围成。
在一些实施例中，显示基板21具有多行子像素区域101。
示例的，第一颜色子像素区域和第二颜色子像素区域位于奇数行，第三颜色子像素区域位于偶数行；或者，第一颜色子像素区域和第二颜色子像素区域位于偶数行，第三颜色子像素区域位于奇数行。
在一些实施例中，第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域可以互为红色子像素区域、绿色子像素区域、以及蓝色子像素区域；或者，第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域可以互为青色子像素区域、黄色子像素区域、以及品红色子像素区域。
本公开的实施例中，一方面，由于第三颜色子像素区域所在行的第一电极123的个数，为第一颜色子像素区域和第二颜色子像素区域所在行的第一电极123的个数的一半，因此，通过将镂空区域103设在与相邻第三颜色子像素区域对应的第一电极123之间，可使镂空区域103的面积最大化，从而增大照射到采集部14上的光线的强度。另一方面，由于镂空区域103位于与第三颜色子像素区域对应的相邻第一电极123之间，即，与第一颜色子像素区域对应的第一电极123和与第二颜色子像素区域对应的第一电极123之间、与第一颜色子像素区域对应的第一电极123和与第三颜色子像素区域对应的第一电极123之间、与第二颜色子像素区域对应的第一电极123和与第三颜色子像素区域对应的第一电极123之间均直接接触，相较于第一电极层中部分相邻的第一电极123 之间直接接触、另一部分未直接接触，本公开的实施例可改善因多个第一电极123上的电压不同而产生压降(IR Drop)的问题。
在一些实施例中，如图2和图6所示，第一颜色子像素区域为蓝色子像素区域，第二颜色子像素区域为红色子像素区域，第三颜色子像素区域为绿色子像素区域。
本公开的实施例中，由于人眼对绿光最敏感，因此，可使绿色子像素区域稀疏排布，以在显示装置显示白光时，人眼看到的白光显示更均匀。
在一些实施例中，如图6所示，与第一颜色子像素区域对应的第一电极123的形状及面积，和与第二颜色子像素区域对应的第一电极123的形状及面积均相同。
在一些实施例中，利用掩模板采用蒸镀的方式制备第一电极层，掩模板包括第一子掩模板、第二子掩模板、第三子掩模板以及第四子掩模板中的一个或多个。
在一些实施例中，采用蒸镀的方式制备第一电极层。其中，掩模板的开口区域，对应第一电极层所在的区域。
在一些实施例中，本公开的实施例中的第一电极层的制备过程为：
第一种情况：如图8所示，先利用掩模板的第一子掩模板制备与蓝色子像素区域对应的第一电极123；如图9所示，再利用第一子掩模板制备与红色子像素区域对应的第一电极123；如图6所示，最后利用掩模板的第四子掩模板制备与绿色子像素区域对应的第一电极123。
第二种情况：先利用第一子掩模板制备与红色子像素区域对应的第一电极123；再利用第一子掩模板制备与蓝色子像素区域对应的第一电极123；最后利用第四子掩模板制备与绿色子像素区域对应的第一电极123。
第三种情况：先利用第四子掩模板制备与绿色子像素区域对应的第一电极123；再利用第一子掩模板制备与蓝色子像素区域对应的第一电极123；最后利用第一子掩模板制备与红色子像素区域对应的第一电极123。
第四种情况：先利用第四子掩模板制备与绿色子像素区域对应的第 一电极123；再利用第一子掩模板制备与红色子像素区域对应的第一电极123；最后利用第一子掩模板制备与蓝色子像素区域对应的第一电极123。
在本公开的实施例中，第一子掩模板的图案与第四子掩模板的图案可以相同，也可以不相同。
本公开的实施例中，相较于分别与第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域对应的第一电极123的形状和面积均不相同，本公开的实施例可使与第一颜色子像素区域和第二颜色子像素区域对应的第一电极123均通过第一子掩模板制备得到，从而节省一道掩模板，降低第一电极层的制备成本。
在一些实施例中，如图7所示，与第三颜色子像素区域对应的第一电极123的形状及面积，和与第一颜色子像素区域对应的第一电极123的形状及面积均相同。
本公开的实施例中，相较于分别与第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域对应的第一电极123的形状和面积均不相同，本公开的实施例可使与第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域对应的第一电极123通过同一道掩模板制备得到，从而节省两道掩模板，降低第一电极层的制备成本。
在一些实施例中，如图10和图11所示，多个子像素区域101呈阵列排布。
在一些实施例中，不对与阵列排布的多个子像素区域101对应的第一电极123的排布方式进行限定。
示例的，如图10和图11所示，子像素区域101具有M列，沿行方向，至少部分相邻的第一电极123之间直接接触；沿列方向，位于第X列的至少部分相邻的第一电极123之间直接接触；1≤X≤M，X和M均为正整数。
在一些实施例中，当显示基板21应用于显示装置时，显示装置还包括与发光器件层12电连接的像素电路，像素电路包括栅线。其中，行方向可以是与栅线的延伸方向相同的方向，也可以是与栅线的延伸方向垂直的方向。
在一些实施例中，如图10所示，沿行方向，位于同一行的所有相邻的第一电极123之间直接接触；沿列方向，位于第X列的所有相邻的第一电极123之间直接接触。
或者，如图11所示，位于同一行的部分相邻的第一电极123之间直接接触，另一部分相邻的第一电极123之间通过导电结构124电连接；沿列方向，位于第X列的部分相邻的第一电极123之间直接接触，另一部分相邻的第一电极123之间通过导电结构124电连接。
在一些实施例中，采用蒸镀的方式制备第一电极层。其中，掩模板的开口区域，对应第一电极层所在的区域。
在一些实施例中，本公开的实施例中的第一电极层的制备过程为：
第一种情况：先利用掩模板的第二子掩模板形成与第X列子像素区域对应的第一电极123；之后，再利用掩模板的第三子掩模板形成其他的第一电极123。第二种情况：先利用掩模板的第三子掩模板形成其他的第一电极123；之后，再利用掩模板的第二子掩模板形成与第X列子像素区域对应的第一电极123。
这样一来，通过第二子掩模板形成的第一电极123与通过第三子掩模板形成的第一电极123中相邻的部分，不但可以直接接触，还可以部分重叠，以避免因工艺误差，而导致两次形成的第一电极123之间电连接不充分。
当然，第一电极层中的多个第一电极123之间还可以通过其他方式电连接，本公开的实施例对此不作特殊限定。
在一些实施例中，如图6和图7所示，至少部分相邻的第一电极123在非子像素区域102有交叠。
本公开的实施例中，通过使相邻第一电极123在非子像素区域102有交叠，一方面，可以避免因工艺误差导致原本应直接接触的第一电极123之间未直接接触，从而使得第一电极层中的所有第一电极123上的电压不同，影响显示装置正常显示；另一方面，由于第一电极123的透过率较低，若相邻第一电极123的重叠部分位于子像素区域101，将会导致显示装置显示的画面亮度不均，因此，通过使相邻第一电极123的重叠 部分位于非子像素区域102，可以避免第一电极123影响显示装置的显示效果。
在一些实施例中，如图6和图7所示，第一电极123与子像素区域101一一对应；第一电极123的边沿超出与其对应的子像素区域101的边沿，且到该子像素区域101的边沿的距离处处相等。
本公开的实施例中，为了避免在蒸镀时因对位误差，导致部分第一电极123未完全覆盖与其对应的子像素区域101，可使得与子像素区域101对应的第一电极123的边沿，超出该子像素区域101的边沿，且到该子像素区域101的边沿的距离处处相等。
本公开的实施例还提供一种显示装置，包括前述任一实施例所述的显示基板21。显示装置还可以包括设置于背离发光器件层12的出光侧一侧的采集部14，采集部14在显示基板21所在的平面上的正投影位于相邻第一电极123之间的镂空区域103在显示基板21所在的平面上的正投影内或者位于相邻第二电极121之间的区域在显示基板21所在的平面上的正投影与镂空区域103在显示基板21所在的平面上的正投影的重叠区域内，以接收来自显示装置的出光侧的采集信号。
在一些实施中，不对采集部14的具体设置位置进行限定，只要采集部14设置于背离发光器件层12的出光侧的一侧即可。若发光器件层12为顶发光，则采集部14设置于发光器件层12背离封装层22一侧；若发光器件层12为底发光，则采集部14设置于发光器件层12背离衬底10一侧，例如采集部14可以设置在封装层22背离衬底10一侧。
在一些实施中，显示基板21包括采集部14；或者，采集部14也可以独立设置于电路板3上，该电路板3集成于显示基板21上。
示例的，显示基板21包括采集部14。如图3所示，采集部14设置于衬底10背离发光器件层12一侧；或者，如图4所示，采集部14也可以设置于薄膜晶体管11与发光器件层12之间；或者，如图5所示，采集部14也可以设置于衬底10与薄膜晶体管11之间。
当然，采集部14还可以设置在显示装置中的其他位置，本公开的实施例对此不作特殊限定。
在一些实施例中，当采集部14设置于薄膜晶体管11背离发光器件层12一侧时，由于薄膜晶体管11不透光，因此，为了使采集部14接收到采集信号，采集信号不能被薄膜晶体管11遮挡。
在一些实施例中，当采集部14设置于薄膜晶体管11背离发光器件层12一侧时，采集部14在衬底10上的正投影与薄膜晶体管11在衬底10上的正投影无交叠。
在一些实施例中，采集部14用于接收采集信号，并且部分采集部14还可以发出信号。
不对采集部14的具体结构进行限定，并且采集部14可以具有各种功能。
示例的，采集部14包括摄像头、指纹识别器、体征采集器中的至少一种。当然，采集部14还可以是其他功能的结构，本公开的实施例对此不作特殊限定。
摄像头例如可以是红外摄像头。红外摄像头发出的红外光照射到被拍摄物体上，经被拍摄物体反射，再反射至红外摄像头的接收器上，接收器对自身接收的光线进行处理，以构成拍摄画面。
指纹识别器例如可以是光学式指纹识别器。显示装置的显示用光照射到手指等带有纹路的待检测物上，经待检测物的谷、脊反射，部分显示光反射至光学式指纹识别器上，光学式指纹识别器将光信号转换成电信号，并得到纹路图像。
体征采集器例如可以是光学式体征采集器。可根据人体皮肤对光的反射，来检测心跳、血红蛋白含量等。
在一些实施例中，采集信号例如可以是光信号。其中，光信号可以是可见光信号，或非可见光信号。
随着智能手机的普及和其更新速度的加快，消费者们对智能手机提出了更高的要求。目前，智能手机的显示屏幕逐渐向全屏显示的方向发展，然而，摄像头、指纹识别器、体征采集器等结构将影响智能手机的屏占比。
相关技术中，通常将摄像头等设置在显示面板2下方，来实现全屏显示的效果。然而，发光器件层的阴极通常为设置于显示区的一整层结构，且阴极的材料包括金属，其光透过率非常低，仅有非常少一部分光线可透过阴极照射到摄像头上，摄像头接收到的光线的强度过低，将影响拍摄效果。
而本公开的实施例提供一种显示装置，通过将采集部14设置在相邻第二电极121之间的区域与镂空区域103的重叠区域，一方面，可避免采集部14影响显示面板2的正常显示；另一方面，由于第一电极层在采集部14的设置区域镂空，光线可不经过第一电极123入射至采集部14，因此，还可提高入射至采集部14的光线的强度，从而提高采集部14的精确度。
本公开的实施例还提供一种显示基板21的制备方法，显示基板21具有多个子像素区域101和位于相邻子像素区域101之间的非子像素区域102。
显示基板21的制备方法包括：利用掩模板在衬底10上形成第一电极层，第一电极层包括：多个相互电连接的第一电极123，以及部分相邻第一电极123之间的镂空区域103，镂空区域103位于非子像素区域102内。
在一些实施例中，第一电极123为阴极，即，发光器件层12共阴极；或者，第一电极123为阳极，即发光器件层12为共阳极。
在一些实施中，第一电极123可以覆盖一个子像素区域101，也可以覆盖多个子像素区域101。
在一些实施例中，根据实际需求，子像素区域101可以是任意形状。示例的，如图2所示，子像素区域101的形状为六边形；如图10所示，子像素区域101的形状为矩形。
在一些实施例中，第一电极123与子像素区域101一一对应，第一电极123的形状和与其对应的子像素区域101的形状可以相同或不同，只要第一电极123完全覆盖与其对应的子像素区域101即可。
示例的，如图2所示，第一电极123和与其对应的子像素区域101 的形状均为六边形。
在一些实施例中，显示基板21具有显示区，显示区中除子像素区域101以外的区域即为非子像素区域102。
在一些实施例中，所有第一电极123均电连接，且部分相邻的第一电极123之间具有镂空区域103。即，除用于构成镂空区域103的相邻的第一电极123，其他相邻的第一电极123之间无镂空区域103；即，其他相邻的第一电极123之间直接接触。
在一些实施例中，不对第一电极123的尺寸进行限定，只要所有第一电极123电连接、且部分相邻的第一电极123之间具有镂空区域103即可。
在一些实施例中，如图2所示，相邻且直接接触的第一电极123在衬底10上的正投影无交叠；或者，如图6所示，相邻且直接接触的第一电极123在衬底10上的正投影部分交叠。
在一些实施例中，如图6所示，相邻且直接接触的第一电极123在衬底10上的正投影的交叠部分位于非子像素区域102。
本公开的实施例提供一种显示基板21的制备方法，利用掩模板在衬底10上形成第一电极层，第一电极层包括多个电连接的第一电极123，部分相邻的第一电极123之间具有镂空区域103，镂空区域103在非子像素区域102内。这样一来，可大大提高显示基板21中镂空区域103的部分的光透过率，当所述显示基板21应用于显示装置时，可在背离发光器件层12的出光侧一侧设置接收光信号的采集部14，以使显示装置实现更多功能。
在一些实施例中，如图2、图6和图7所示，所述第一电极123与所述子像素区域101一一对应；多个所述子像素区域101包括多行子像素区域101，所述多行子像素区域101包括多个第一颜色子像素区域、多个第二颜色子像素区域、以及多个第三颜色子像素区域；奇数行或偶数行子像素区域中的每一行子像素区域包括所述第一颜色子像素区域和所述第二颜色子像素区域；并且偶数行或奇数行子像素区域中的每一行子像素区域包括所述第三颜色子像素区域，与偶数行或奇数行子像素区域中的每一行子像素区域中的所述第三颜色子像素区域对应的所述第一电极 123与所述镂空区域103沿行方向交替排列。根据一些示例，沿行方向，所述第三颜色子像素区域与所述第一颜色子像素区域和所述第二颜色子像素区域均错开设置，并且与所述第三颜色子像素区域对应的所述第一电极123和与所述第一颜色子像素区域和所述第二颜色子像素区域对应的所述第一电极123均错开设置；奇数行或偶数行子像素区域中的每一行子像素区域中的所述第一颜色子像素区域和所述第二颜色子像素区域对应的所述第一电极123中的相邻的第一电极123直接接触，并与在行方向位于所述相邻的第一电极123之间、在列方向与所述相邻的第一电极123相邻且与所述第三颜色子像素区域对应的所述第一电极123直接接触。
在一些实施例中，如图2、图6和图7所示，第一电极123与子像素区域101一一对应；多个子像素区域101包括多个第一颜色子像素区域、多个第二颜色子像素区域、以及多个第三颜色子像素区域；第一颜色子像素区域和第二颜色子像素区域位于同一行且交替设置，第三颜色子像素区域位于所述第一颜色子像素区域的相邻行；沿行方向，第三颜色子像素区域与第一颜色子像素区域和第二颜色子像素区域均错开设置；沿行方向，与第一颜色子像素区域对应的第一电极123和与第二颜色子像素区域对应的第一电极123直接接触；沿列方向，与第三颜色子像素区域对应的第一电极123，和与其错开且与第一颜色子像素和第二颜色子像素对应的第一电极123直接接触；镂空区域103位于与第三颜色子像素区域对应的、沿行方向排布的相邻第一电极123之间。
即，镂空区域103由与相邻的第三颜色子像素区域对应的第一电极123、以及与位于相邻第三颜色子像素区域之间的第一颜色子像素区域和/或第二颜色子像素区域对应的第一电极123围成。
在一些实施例中，显示基板21具有多行子像素区域101。
示例的，第一颜色子像素区域和第二颜色子像素区域位于奇数行，第三颜色子像素区域位于偶数行；或者，第一颜色子像素区域和第二颜色子像素区域位于偶数行，第三颜色子像素区域位于奇数行。
在一些实施例中，第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域可以互为红色子像素区域、绿色子像素区域、以 及蓝色子像素区域；或者，第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域可以互为青色子像素区域、黄色子像素区域、以及品红色子像素区域。
本公开的实施例中，一方面，由于第三颜色子像素区域所在行的第一电极123的个数，为第一颜色子像素区域和第二颜色子像素区域所在行的第一电极123的个数的一半，因此，通过将镂空区域103设在与相邻第三颜色子像素区域对应的第一电极123之间，可使镂空区域103的面积最大化，从而增大照射到采集部14上的光线的强度。另一方面，由于镂空区域103位于与第三颜色子像素区域对应的相邻第一电极123之间，即，与第一颜色子像素区域对应的第一电极123和与第二颜色子像素区域对应的第一电极123之间、与第一颜色子像素区域对应的第一电极123和与第三颜色子像素区域对应的第一电极123之间、与第二颜色子像素区域对应的第一电极123和与第三颜色子像素区域对应的第一电极123之间均直接接触，相较于第一电极层中部分相邻的第一电极123之间直接接触，另一部分未直接接触，本公开的实施例可改善因多个第一电极123上的电压不同而产生IR Drop的问题。
在一些实施例中，如图2和图6所示，第一颜色子像素区域为蓝色子像素区域，第二颜色子像素区域为红色子像素区域，第三颜色子像素区域为绿色子像素区域。
本公开的实施例中，由于人眼对绿光最敏感，因此，可使绿色子像素区域稀疏排布，以在显示装置显示白光时，人眼看到的白光显示更均匀。
在一些实施例中，利用掩模板形成第一电极层，包括：利用掩膜版的第一子掩模板分别形成与第一颜色子像素区域对应的第一电极123和与第二颜色子像素区域对应的第一电极123。
在一些实施例中，第一子掩模板的包括第一开口区，第一开口区用于分别形成与第一颜色子像素区域对应的第一电极123和与第二颜色子像素区域对应的第一电极123。
在一些实施例中，本公开的实施例中的第一电极层的制备过程可以为：
第一种情况：如图8所示，先利用掩模板的第一子掩模板制备与蓝色子像素区域对应的第一电极123；如图9所示，再利用第一子掩模板制备与红色子像素区域对应的第一电极123；如图6所示，最后利用掩模板的第四子掩模板制备与绿色子像素区域对应的第一电极123。
第二种情况：先利用第一子掩模板制备与红色子像素区域对应的第一电极123；再利用第一子掩模板制备与蓝色子像素区域对应的第一电极123；最后利用第四子掩模板制备与绿色子像素区域对应的第一电极123。
第三种情况：先利用第四子掩模板制备与绿色子像素区域对应的第一电极123；再利用第一子掩模板制备与蓝色子像素区域对应的第一电极123；最后利用第一子掩模板制备与红色子像素区域对应的第一电极123。
第四种情况：先利用第四子掩模板制备与绿色子像素区域对应的第一电极123；再利用第一子掩模板制备与红色子像素区域对应的第一电极123；最后利用第一子掩模板制备与蓝色子像素区域对应的第一电极123。
在本公开的实施例中，第一子掩模板的图案与第四子掩模板的图案可以相同，也可以不相同。
本公开的实施例中，相较于分别与第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域对应的第一电极123的形状和面积均不相同，本公开的实施例可使与第一颜色子像素区域和第二颜色子像素区域对应的第一电极123均通过第一子掩模板制备得到，从而节省一道掩模板，降低第一电极层的制备成本。
在一些实施例中，如图7所示，利用所述掩模板形成第一电极层，还包括：利用第一子掩模板形成与第三颜色子像素区域对应的第一电极123。
本公开的实施例中，相较于分别与第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域对应的第一电极123的形状和面积均不相同，本公开的实施例可使与第一颜色子像素区域、第二颜色子像素区域、以及第三颜色子像素区域对应的第一电极123通过同一道掩模板制备得到，从而节省两道掩模板，降低第一电极层的制备成本。
在一些实施例中，如图10和图11所示，多个子像素区域101呈阵 列排布。
在一些实施例中，不对与阵列排布的多个子像素区域101对应的第一电极123的排布方式进行限定。
在一些实施例中，第一电极123与子像素区域101一一对应；子像素区域101具有M列；利用掩模板在衬底10上形成第一电极层，包括：沿列方向，利用掩膜版的第二子掩模板形成与第X列子像素区域对应的第一电极123；沿行方向，利用掩模板的第三子掩模板形成其他的第一电极123；其中，沿行方向，至少部分相邻的第一电极123之间直接接触；沿列方向，位于第X列的至少部分相邻的第一电极123之间直接接触；1≤X≤M，X和M均为正整数。
在一些实施例中，当显示基板21应用于显示装置时，显示装置还包括与发光器件层12电连接的像素电路，像素电路包括栅线。其中，行方向可以是与栅线的延伸方向相同的方向，也可以是与栅线的延伸方向垂直的方向。
在一些实施例中，如图10所示，沿行方向，位于同一行的所有相邻的第一电极123之间直接接触；沿列方向，位于第X列的所有相邻的第一电极123之间直接接触。
或者，如图11所示，位于同一行的部分相邻的第一电极123之间直接接触，另一部分相邻的第一电极123之间通过导电结构124电连接；沿列方向，位于第X列的部分相邻的第一电极123之间直接接触，另一部分相邻的第一电极123之间通过导电结构124电连接。
在一些实施例中，采用蒸镀的方式制备第一电极层。其中，掩模板的开口区域，对应第一电极层所在的区域。
在一些实施例中，本公开的实施例中的第一电极层的制备过程为：
第一种情况：先利用掩模板的第二子掩模板形成与第X列子像素区域对应的第一电极123；之后，再利用掩模板的第三子掩模板形成其他的第一电极123。第二种情况：先利用掩模板的第三子掩模板形成其他的第一电极123；之后，再利用掩模板的第二子掩模板形成与第X列子像素区域对应的第一电极123。
这样一来，通过第二子掩模板形成的第一电极123与通过第三子掩模板形成的第一电极123中相邻的部分，不但可以直接接触，还可以部分重叠，以避免因工艺误差，而导致两次形成的第一电极123之间电连接不充分。
当然，第一电极层中的多个第一电极123之间还可以通过其他方式电连接，本公开的实施例对此不作特殊限定。
本公开的实施例还提供一种掩模板，用于利用蒸镀的方式制备前述任一实施例所述的显示基板21中的发光器件层的第一电极层。
本公开的实施例提供的掩模板，与前述显示基板21的说明与效果相同，在此不再赘述。
本公开的实施例提供一种显示基板及其制备方法、显示装置、掩模板，发光器件层包括第一电极层，第一电极层包括多个电连接的第一电极，部分相邻的第一电极之间具有镂空区域，镂空区域在非子像素区域内。这样一来，可大大提高发光器件层中位于镂空区域的部分的光透过率，当所述发光器件层应用于显示装置时，可在背离发光器件层的出光侧一侧设置接收光信号的采集部，以使显示装置实现更多功能。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
