显示面板及显示装置
本申请要求在2020年03月10日提交中国专利局、申请号为202010161496.6的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及显示面板技术领域，例如涉及一种显示面板及显示装置。
背景技术
随着电子设备的快速发展，用户对屏占比的要求越来越高，使得电子设备的全面屏显示受到业界越来越多的关注。电子设备如手机、平板电脑等，由于需要集成诸如前置摄像头、听筒以及红外感应元件等器件，故需要在显示屏上开槽(Notch)，在开槽区域设置摄像头、听筒以及红外感应元件等，但是这些电子设备均不是真正意义上的全面屏，并不能在整个屏幕的每个区域均进行显示，如在摄像头区域不能显示画面。
为实现真正的全面屏，屏下摄像头技术应运而生，即显示屏中设置有摄像头的区域仍可以用于显示，或者说显示屏中设置有摄像头的区域仍设置有像素。但是对于显示屏中设置有摄像头的区域，像素中不透光的金属结构之间会形成有规律的狭缝，外界光线通过显示面板中设置有摄像头的区域时会发生衍射，严重影响摄像头的拍摄效果。
发明内容
本公开提供一种显示面板及显示装置，可以提升透明显示区域的透明度，同时降低衍射影响。
提供了一种显示面板，包括：透明显示区；
透明显示区内设置有多个子像素，多个子像素沿至少一个方向呈直线排列，沿至少一个方向排列的每排子像素中，至少部分两两相邻的子像素中的每两两相邻的子像素中的一个子像素的下电极呈第一形状类型，另一个子像素的下电极呈第二形状类型，第一形状类型包括圆形或椭圆形，第二形状类型与另一个子像素的发光区域的形状相同。通过将一部分子像素的下电极设置呈第一形状类型，另一部分子像素的下电极呈第二形状类型，可以有效避免子像素间的下电极之间形成规律狭缝，从而降低衍射影响，提升摄像头等感光器件的拍照效果，并提高下电极的面积利用率，从而提高透明显示区的透明度。
可选地，对沿至少一个方向排列的每排子像素进行划分，得到多个第一重复单元，每个第一重复单元具有连续排列的三个子像素，至少部分第一重复单元中的两个相邻的子像素的下电极呈第一形状类型，另一个子像素的下电极呈第二形状类型，通过将每个第一重复单元中的一部分子像素的下电极设置呈第一形状类型，另一部分子像素的下电极呈第二形状类型，以均匀排布两种类型的下电极，以提高透明显示区各处的透光率，改善透明显示区各处的衍射现象。
可选地，下电极呈第二形状类型的子像素为绿色子像素。由于红色子像素、绿色子像素和蓝色子像素中，绿色子像素的发光区域尺寸最大，将绿色子像素的下电极设置为第二形状类型，可以提高绿色子像素的下电极的面积利用率，减少下电极与发光区域不重叠的区域的面积，提高透明显示区的透明度。
可选地，对沿至少一个方向排列的每排子像素进行划分，得到多个第一重复单元，每个第一重复单元具有连续排列的三个子像素，至少部分第一重复单元中的两个相邻的子像素的下电极呈第二形状类型，另一个子像素的下电极呈第一形状类型，通过将每个第一重复单元中的一部分子像素的下电极设置呈第一形状类型，另一部分子像素的下电极呈第二形状类型，以均匀排布两种类型的下电极，以提高透明显示区各处的透光率，改善透明显示区各处的衍射现象。
可选地，下电极呈第二形状类型的两个子像素为绿色子像素和蓝色子像素。由于绿色子像素和蓝色子像素的发光区域尺寸大于红色子像素的发光区域尺寸，将绿色子像素和蓝色子像素的下电极设置为第二形状类型，可以提高绿色子像素和蓝色子像素的下电极的面积利用率，减少下电极与发光区域不重叠的区域的面积，提高透明显示区的透明度。
可选地，沿至少一个方向排列的一排子像素中，下电极呈第一形状类型的子像素和下电极呈第二形状类型的子像素交替排列，以提高透明显示区各处的透光率，改善透明显示区各处的衍射现象。
可选地，沿第一方向相邻设置的两个像素对应的三角形沿第二方向的顶点的指向相反；其中，第一方向与第二方向垂直。沿第一方向相邻设置的两个像素中，每个像素沿第一方向翻转180°后其内部子像素的排布结构与同一排中相邻的像素内的子像素的排布结构相同，像素排布更紧密，有利于减小像素间距，提高显示装置的分辨率。
可选地，子像素呈矩阵排列，沿子像素排列的行方向和列方向，下电极呈第一形状类型的子像素和下电极呈第二形状类型的子像素交替排列，以提高透明显示区各处的透光率，改善透明显示区各处的衍射现象。
还提供了一种显示装置，包括：如上所述的显示面板，及设置于所述显示 面板的透明显示区下方的感光部件。通过将一部分子像素的下电极设置呈第一形状类型，另一部分子像素的下电极呈第二形状类型，可以有效避免子像素间的下电极之间形成规律狭缝，从而降低衍射影响，提升摄像头等感光器件的拍照效果，并提高下电极的面积利用率，从而提高透明显示区的透明度。
本公开的技术方案中的显示面板包括：透明显示区；透明显示区内设置有多个子像素，子像素沿至少一个方向呈直线排列，沿至少一个方向排列的每排子像素中，至少部分两两相邻的子像素中的每两两相邻的子像素中的一个子像素的下电极呈第一形状类型，另一个子像素的下电极呈第二形状类型，第一形状类型包括圆形或椭圆形，下电极呈第二形状类型的子像素的下电极与其发光区域的形状相同，通过将一部分子像素的下电极设置呈第一形状类型，可以有效避免子像素间的下电极之间形成规律狭缝，从而降低衍射影响，提升摄像头等感光器件的拍照效果；另一部分子像素的下电极呈第二形状类型，有利于节省下电极占用面积，提高透明显示区的面积利用率，从而提高透明显示区的透明度。

具体实施方式
下面结合附图和实施例对本公开作说明。
本实施例提供一种显示面板。图1为一实施例提供的一种显示面板的结构示意图。图2为一实施例提供的一种显示面板的透明显示区的局部结构示意图。 图3为一实施例提供的一种显示面板的透明显示区的局部剖面结构示意图。结合图1至图3所示，该显示面板包括：透明显示区10。
透明显示区10内设置有多个子像素11，多个子像素11沿至少一个方向呈直线排列，沿至少一个方向排列的每排子像素11中，至少部分两两相邻的子像素11中的每两两相邻的子像素11中的一个子像素11的下电极111呈第一形状类型，另一个子像素11的下电极111呈第二形状类型，第一形状类型包括圆形或椭圆形，下电极111呈第二形状类型的子像素11的下电极111与其发光区域112的形状相同。
显示面板的整个显示区可以是部分透明或是全部透明，可根据需要设置透明显示区的大小，本实施例对此不做限定。图1示例性的画出显示面板的整个显示区为透明显示区的情况。图2示例性地示出了透明显示区10的局部区域101内的子像素11沿第一方向Y呈直线排列的情况，子像素11还可以沿第二方向X呈直线排列，本实施例对此不做限定。透明显示区10的其他区域的像素排布与局部区域101内的像素排布相同或类似。可选的，子像素11的发光区域112的形状包括下述至少一种：三角形、正方形、五边形、圆形、椭圆形、长方形和圆角矩形。可选的，第二形状类型包括下述至少一种：三角形、方形、五边形、圆形、椭圆形和圆角矩形。透明显示区10内的所有子像素11的发光区域112的形状可以相同或不同。第一形状类型和第二形状类型的形状可以相同或不同。图2示例性的画出所有子像素11的发光区域112的形状为相同的情况。图2示例性的画出所有子像素11的发光区域112的形状为圆角矩形，第二形状类型为圆角矩形的情况。多个子像素11可包括红色子像素R、绿色子像素G和蓝色子像素B。
图3为一子像素沿图2中A1A2方向的剖面结构示意图。如图3所示，显示面板还包括衬底40、位于衬底40上的驱动线路层以及位于驱动线路层远离衬底40一侧的发光单元。发光单元可以是有机发光二极管。发光单元包括沿远离衬底40的方向层叠设置的下电极111、发光功能层(即发光区域112)和上电极113。子像素11的下电极111可以是阳极。驱动线路层可包括层叠设置的有源层114、多个导电层和多个无机绝缘层，以形成像素驱动电路中的薄膜晶体管、存储电容等器件，以及扫描线、数据线和发光控制线等。薄膜晶体管可包括半导体有源层114、栅极绝缘层115、栅极116、层间绝缘层117、源极118和漏极119。子像素11可包括像素驱动电路和发光单元，发光单元的下电极111通过贯穿平坦化层60的过孔与薄膜晶体管的漏极119电连接。像素驱动电路与对应的扫描线、数据线和发光控制线等电连接，以接收扫描信号、数据信号和发光控制信号等，进而输出驱动电流至发光单元，以控制对应的发光单元的发光亮度和时间等。显示面板还包括缓冲层50，缓冲层50位于衬底40和半导体有 源层114之间。驱动线路层还包括像素限定层70，位于平坦化层60和下电极111远离衬底40的一侧，像素限定层70设置有像素开口，像素开口暴露下电极111，发光功能层和上电极113覆盖像素开口。一个像素开口可对应一个发光单元。一个发光单元可对应一个子像素11。子像素11的发光区域112即为发光功能层所在区域。可选的，沿显示面板的厚度方向Z，子像素11的发光区域112在其下电极111上的投影位于下电极111内。方向Z可垂直于第一方向Y。方向Z可垂直于第二方向X。第一方向Y可垂直于第二方向X。子像素11的发光区域112可位于子像素11的下电极111的中间区域。
下电极111为非透明材料。子像素11的下电极111未被发光功能层(即发光区域112)覆盖的区域，既不发光也不透明，故子像素11的下电极111未被发光功能层(即发光区域112)覆盖的区域越小，不透明区域占比越小，透明区域占比越大，即子像素11的发光区域112与其下电极111的面积比值S1/S2越大。子像素11的下电极111呈第二形状类型，则说明子像素11的下电极111与其发光区域112的形状相同，则说明子像素11的发光区域112的面积S1与其下电极111的面积S2的比值S1/S2很大。可选的，下电极111呈第一形状类型的子像素11的发光区域112与其下电极111的面积比值S1/S2小于或等于下电极111呈第二形状类型的子像素11的发光区域112与其下电极111的面积比值S1/S2。下电极111呈第一形状类型的子像素11的下电极111的面积利用率小于或等于下电极111呈第二形状类型的子像素11的下电极111的面积利用率。制作有机发光二极管的发光功能层的精密金属掩膜版(Fine Metal Mask，FMM)上的开口可设计成接近方形或近圆形，为了提升开口率，子像素11的发光区域112也可设计成接近方形或近圆形。
若子像素11的下电极111呈第一形状类型，例如可以是圆形或椭圆形，可以有效避免子像素间的下电极之间容易形成长条走线或规律狭缝，导致外界光线通过透明显示区时发生衍射，从而降低衍射影响，提升摄像头等感光器件的拍照效果。若子像素11的下电极111呈第二形状类型，使得子像素11的下电极111未被发光功能层覆盖的区域较小，有利于提高透明显示区10的透明度。通过将一部分子像素11的下电极111设置呈第一形状类型，另一部分子像素11的下电极111呈第二形状类型，可以有效避免子像素间的下电极之间形成规律狭缝，从而降低衍射影响，提升摄像头等感光器件的拍照效果，并提高下电极的面积利用率，从而提高透明显示区10的透明度。
本实施例的技术方案中的显示面板包括：透明显示区；透明显示区内设置有多个子像素，多个子像素沿至少一个方向呈直线排列，沿至少一个方向排列的每排子像素中，至少部分两两相邻的子像素中的每两两相邻的子像素中的一个子像素的下电极呈第一形状类型，另一个子像素的下电极呈第二形状类型， 第一形状类型包括圆形或椭圆形，下电极呈第二形状类型的子像素的下电极与其发光区域的形状相同，通过将一部分子像素的下电极设置呈第一形状类型，另一部分子像素的下电极呈第二形状类型，可以有效避免子像素间的下电极之间形成规律狭缝，从而降低衍射影响，提升摄像头等感光器件的拍照效果，并提高下电极的面积利用率，从而提高透明显示区的透明度。
本实施例还提供一种显示面板。在上述实施例的基础上，参见图2，对沿至少一个方向排列的每排子像素11进行划分，得到多个第一重复单元12，每个第一重复单元12具有连续排列的三个子像素111，至少部分第一重复单元12中的每个第一重复单元12中的两个相邻的子像素11的下电极111呈第一形状类型，另一个子像素11的下电极111呈第二形状类型。
图2示例性地标出了多个第一重复单元12，其余第一重复单元可按子像素11的排列次序和形状依次确定，本实施例对第一重复单元12的个数不做限定。沿至少一个方向排列的每排子像素11，每三个子像素11形成一个第一重复单元12，相邻的两个第一重复单元12中的六个子像素11依次相邻连续排列。两个相邻的且下电极111呈第一形状类型的子像素11可以是红色子像素R、绿色子像素G和蓝色子像素B中的任意两种。图2示例性的画出两个相邻的且下电极111呈第一形状类型的子像素11为红色子像素R和蓝色子像素B的情况。通过将每个第一重复单元12中的一部分子像素11的下电极111设置呈第一形状类型，另一部分子像素11的下电极111呈第二形状类型，均匀排布两种类型的下电极111，以提高透明显示区10的透光率，改善透明显示区10的衍射现象。
可选的，在上述实施例的基础上，参见图2，至少部分第一重复单元12中，下电极111呈第二形状类型的子像素11为绿色子像素G。图2示例性的画出绿色子像素G的下电极11呈第二形状类型，红色子像素R的下电极111和蓝色子像素B的下电极111呈第一形状类型的情况。由于红色子像素R、绿色子像素G和蓝色子像素B中，绿色子像素G的发光区域112尺寸最大，将绿色子像素G的下电极111设置为第二形状类型，可以提高绿色子像素G的下电极111的面积利用率，减少下电极111与发光区域112不重叠的区域的面积，提高透明显示区10的透明度。
本实施例还提供一种显示面板。图4为一实施例提供的又一种显示面板的透明显示区的结构示意图。在上述实施例的基础上，对沿至少一个方向排列的每排子像素11进行划分，得到多个第一重复单元12，每个第一重复单元12具有连续排列的三个子像素11，至少部分第一重复单元12中的每个第一重复单元12中的两个相邻的子像素11的下电极111呈第二形状类型，另一个子像素11的下电极111呈第一形状类型。
第一重复单元12中的两个相邻且下电极111呈第二形状类型的子像素11可以是红色子像素R、绿色子像素G和蓝色子像素B中的任意两种。图4示例性的画出所有子像素11的发光区域112的形状为圆角矩形，第二形状类型为圆角矩形的情况。图4的技术方案相比于图2的技术方案，可以提高透明显示区10的透明度。图2的技术方案相比于图4的技术方案，可以降低衍射影响。
可选的，在上述实施例的基础上，参见图4，至少部分第一重复单元12中，下电极111呈第二形状类型的两个子像素11分别为绿色子像素G和蓝色子像素B。图4示例性的画出所有子像素11的发光区域112呈近似矩形，绿色子像素G的下电极111和蓝色子像素B的下电极111呈近似矩形，红色子像素R的下电极111呈近似圆形的情况。由于红色子像素R、绿色子像素G和蓝色子像素B中，绿色子像素G和蓝色子像素B的发光区域112尺寸大于红色子像素R的发光区域112尺寸，将绿色子像素G和蓝色子像素B的下电极111设置为第二形状类型，可以提高绿色子像素G和蓝色子像素B的下电极111的面积利用率，减少下电极111与发光区域112不重叠的区域的面积，提高透明显示区10的透明度。
本实施例还提供一种显示面板。图5为一实施例提供的又一种显示面板的透明显示区的局部结构示意图。在上述实施例的基础上，沿至少一个方向排列的一排子像素11中，下电极111呈第一形状类型的子像素11和下电极111呈第二形状类型的子像素11交替排列。
图5示例性的画出所有子像素11的发光区域112的形状为圆角矩形，第二形状类型为圆角矩形的情况。图5的技术方案相比于图2的技术方案，可以提高透明显示区10的透明度。图2的技术方案相比于图5的技术方案，可以降低衍射影响。图5的技术方案相比于图4的技术方案，可以降低衍射影响。图4的技术方案相比于图5的技术方案，可以提高透明显示区10的透明度。下电极111呈第一形状类型的子像素11的数量越多，越有利于降低衍射影响；下电极111呈第二形状类型的子像素11的数量越多，越有利于提高透明显示区10的透明度。可根据需要设置子像素11的下电极111的形状，平衡衍射影响和透明度。
可选的，在上述实施例的基础上，参见图2、图4和图5，多个子像素11沿第一方向Y呈直线排列，多个子像素11形成多个像素13，每个像素13包括三个发光颜色不同的子像素11，每个像素13内的两个子像素11沿第一方向Y排列，每个像素13内的三个子像素11的虚拟中心的连线构成三角形。
三个发光颜色不同的子像素11可包括红色子像素R、绿色子像素G和蓝色子像素B。通过控制每个像素13中的三种发光颜色不同的子像素11发出的光的亮度，可以混合形成任意颜色，以使显示面板显示所需画面。子像素11的虚拟 中心可为子像素11的几何中心，示例性的，子像素11的发光区域112呈矩形，则子像素11的虚拟中心为矩形发光区域112的几何中心。
可选的，在上述实施例的基础上，参见图2、图4和图5，沿第一方向Y相邻设置的两个像素13对应的三角形沿第二方向X的顶角的指向相反；其中，第一方向Y与第二方向X垂直。
