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。
目前，为了提高显示装置的屏占比，可以将显示装置中的显示面板设计为局部透光的显示面板。显示装置中的感光传感器的感光面在显示面板上的正投影可以位于该局部透光的区域内，显示装置中的感光传感器位于与显示面板的显示面相对的一侧。示例性的，可以采用以下两种实施方式：
方式一，该显示面板具有：透光显示区和常规显示区。该透光显示区也可以称作屏下摄像头(英文：Full Display with Camera；简写：FDC)区域。常规显示区和透光显示区内均设置有多个发光器件，使得常规显示区和透光显示区均能够显示画面。
位于透光显示区中的多个发光器件，与位于透光显示区两侧的常规显示区中的多个像素驱动电路中的部分像素驱动电路一一对应耦接，该部分像素驱动电路用于控制透光显示区的画面显示。
其中，位于透光显示区中的多个发光器件可以通过多个连接线与对应的常规显示区中的多个像素驱动电路连接，其中，多个连接线中的每一条连接线的一部分位于透光显示区中，另一部分位于常规显示区中。
透光显示区具有多个出线口，该出线口为位于透光显示区中的多个发光器件连接的多个连接线从透光显示区延伸至常规显示区的位置，该多个出线口位于透光显示区靠近位于透光显示区两侧的常规显示区的边缘的位置处。
但是，上述的显示面板中的透光显示区中的发光器件对应的像素驱动电路位于透光显示区的两侧，导致透光显示区中的发光器件连接的连接线的出线口的数量较少，进而导致透光显示区周围的常规显示区的空间利用率较低。
方式二，该显示面板具有：显示区域以及位于所述显示区域外围的外围区域，该显示区域包括常规显示区和透光显示区。该常规显示区具有多个像素驱动电路以及多个发光器件，常规显示区的像素驱动电路可以一一对应的驱动常规显示区中的发光器件；透光显示区中具有多个发光器件，但透光显示区中的 发光器件对应的像素驱动电路位于外围区域中，由该外围区域中的像素驱动电路来驱动透光显示区中的发光器件。如此便可以避免像素驱动电路遮挡光线，使得透光显示区能够具有透光功能。
但是，位于外围区域中的像素驱动电路会使得显示面板的边框较大，使得显示面板的屏占比较小，显示面板的显示效果较差。
请参考图1，图1是一种显示面板的结构示意图。该显示面板10包括：透光显示区11和非透光的常规显示区12。
如图2所示，图2是图1示出的显示面板的透光显示区和常规显示区的线路连接示意图。透光显示区11内设置有第一发光器件111，常规显示区12内可以设置有与第一发光器件耦接的第一像素驱动电路121。其中，每个第一发光器件111与位于透光显示区11两侧的对应的第一像素驱动电路121组成一个第一像素单元，且每个第一发光器件111可以通过连接线13与位于透光显示区11两侧的第一像素驱动电路121对应耦接。
常规显示区12不仅包含了多个第一像素驱动电路121，还包含了多个第二像素单元(图中未示出，第二像素单元包括第二发光器件和第二像素电路)。
透光显示区11具有多个出线口A1，一行第一发光器件111连接的多条连接线13可以通过同一个出线口A1延伸出透光显示区11，并延伸至位于透光显示区11两侧的常规显示区12中。多个出线口A1位于透光显示区11靠近位于透光显示区两侧的常规显示区12的边缘的位置处。
但是，上述的显示面板10中位于透光显示区11的第一发光器件111连接的连接线13的延伸方向均平行于第一发光器件111的行方向，导致位于透光显示区11的第一发光器件111对应的连接线13的排布方式的灵活性较低。
并且，由于透光显示区11中的连接线13的排布数量受到透光显示区11的边缘的周长的限制，理想情况下，可以使得透光显示区11的边缘的一周上均排布有连接线13，以使得透光显示区11中的走线排布空间利用最大化，但是，如图2所示，当透光显示区11中的第一发光器件111连接的连接线13的仅以平行于第一发光器件111的行方向延伸时，透光显示区11的边缘上的A1区域并未排布连接线13，如此，导致透光显示区11中的布线空间的利用率较低。
图3是本申请实施例提供的一种显示面板的俯视图，图4是图3示出的显示面板的局部20A结构示意图，图5是图3示出的显示面板中透光显示区中的 第一发光器件和第一像素驱动电路的连接结构示意图。请参考图3、图4和图5。该显示面板20可以包括：衬底21，多个第一发光器件22、多个第一像素驱动电路23、多条连接线24、多个第二像素驱动电路25以及多个第二发光器件26。
衬底21可以具有透光显示区211，以及位于透光显示区211外围的常规显示区212。示例性的，常规显示区212可以围绕透光显示区211，即透光显示区211可以被常规显示区212包围。透光显示区211也可以设置在其他位置处，透光显示区211的设置位置可根据需要而定。例如，透光显示区211可以位于衬底21基板的顶部正中间位置处，也可以位于衬底21基板的左上角位置或右上角位置处。感光传感器(如，摄像头)等硬件可以设置于显示面板20的透光显示区211。透光显示区211可以为如图3所示的圆形，也可以为方形，还可以为六边形、梯形等其他形状，本申请实施例对此不作限制。
多个第一发光器件22可以位于透光显示区211内，多个第一像素驱动电路23可以位于常规显示区212内，多条连接线24可以位于衬底21上，连接线24的一部分可以位于透光显示区211内，另一部分可以位于常规显示区212内。即就是，位于透光显示区211中的多个发光器件22耦接的多条连接线24可以穿过透光显示区211的边缘处延伸出透光显示区211，并延伸至位于透光显示区211周围的常规显示区212中。多个第一个像素驱动电路23与多个第一发光器件22通过多条连接线24耦接，多个第一像素驱动电路23被配置为驱动多个第一发光器件22发光。
多个第二发光器件26和多个第二像素驱动电路25可以位于常规显示区212内。多个第二像素驱动电路25与多个第二发光器件26耦接，多个第二像素驱动电路25被配置为驱动多个第二发光器件26发光。
其中，多个第一发光器件22包括沿第一方向f1延伸，且沿第二方向f2排布的多组第一发光器件22a，多条连接线24中至少一条连接线24位于透光显示区211内的至少部分线段的延伸方向与第一方向f1之间具有锐角夹角α，第一方向f1和第二方向f2交叉。
需要说明的是，如图5所示，第一方向f1可以不特指某一个绝对方向，由于常规显示区212可以包围透光显示区211，因此多个第一像素驱动电路23可以位于透光显示区211的四周，多个第一像素驱动电路23也可以位于多个第一发光器件22的四周，第一方向f1可以指图4中的多个第一发光器件22的行方向或者列方向。示例性的，图5所示的透光显示区211包括围绕透光显示区211 的中心排布的四个透光分区2111(四个透光分区2111可以分别为：第一透光分区211a、第二透光分区211b、第三透光分区211c以及第四透光分区211d)，第一透光分区211a和第二透光分区211b中的连接线24的排布方式可以沿透光显示区211的对称轴s1对称，该对称轴s1与第一方向f1之间的夹角可以为45度，第一透光分区211a和第二透光分区211b中的第一方向f1也可以沿该对称轴s1对称。如第一透光分区211a中的第一方向f1可以为多个第一发光器件22的行方向，第二透光分区211b中的第一方向f1可以为多个第一发光器件22的列方向。本申请实施例以第一透光分区211a为例进行说明，其他的透光分区中的连接线24的排布方式可以与第一透光分区211a中的连接线24的排布方式沿透光显示区211的对称轴对称。
如此，可以通过设置该锐角夹角α的值，灵活调节至少一条连接线24的延伸方向，可以灵活排布多条连接线24，使得显示面板20上的多条连接线24的排布方式的灵活性较高。
需要说明的是，图4和图5为了便于区分透光显示区211和常规显示区212，透光显示区211和常规显示区212的交界处的发光器件并未完全示出，在实际的显示面板中，透光显示区211和常规显示区212的交界处可以具有多个发光器件，且该多个发光器件可以属于透光显示区211或者常规显示区212。
示例的，每条连接线24中位于透光显示区211的部分可以由透光导电材料制成。这样，可以提高透光显示区211的透光率。为了简化该连接线24的制造工艺，该连接线24可以全部由透光导电材料制成。其中，该透光导电材料可以为氧化铟锡(英文：Indium tin oxide；简写：ITO)。
综上所述，本申请实施例提供了一种显示面板，包括：衬底以及位于衬底上的多个第一发光器件、多个第一像素驱动电路、多条连接线、多个第二发光器件以及多个第二像素驱动电路。位于透光显示区内的多个第一发光器件通过多条连接线与位于常规显示区内多个第一像素驱动电路耦接。其中，多条连接线中至少一条连接线位于透光显示区内的至少部分线段的延伸方向与第一方向之间具有锐角夹角，如此可以通过设置该锐角夹角的值，灵活排布多条连接线，使得显示面板上的多条连接线的排布方式较为灵活。可以解决相关技术中位于透光显示区的第一发光器件对应的连接线的排布方式的灵活性较低的问题，可以实现提高位于透光显示区中的第一发光器件对应的连接线的排布灵活性的效果。
需要说明的是，图4和图5中仅列出了位于透光显示区211中多个第一发光器件22中的部分第一发光器件22，对应的连接线24的走线方式。位于透光显示区211中其他的至少一个第一发光器件22对应的连接线24方式可以与这种走线方式相似。
其中，在本申请实施例中，第一发光器件22和第二发光器件26可以为有机发光二极管(英文：Organic Light-Emitting Diode；简写：OLED)发光器件。发光器件22可以包括：沿垂直且远离衬底21的方向层叠设置的第一电极、发光材料层和第二电极。第一电极可以为发光器件22的阳极，第二电极可以为发光器件22的阴极，阴极可以为整层结构。
第一发光器件22中的第一电极可以与连接线24耦接，以通过连接线24与对应的像素驱动电路耦接。图5中的第一发光器件22是以第一发光器件22的连接位置表示第一发光器件22。连接位置可以指第一发光器件22的第一电极和连接线24的连接位置。
可选地，如图6所示，图6是本申请实施例提供的一种透光分区的连接线结构示意图。图6中为了便于表示多个第一发光器件22的连接方式，仅示出了多个透光分区2111中的一个透光分区2111，其他的透光分区2111的连接方式与图6所示的透光分区2111的连接方式相同。多个第一发光器件22可以通过多条连接线24与多个第一像素驱动电路23一一对应耦接。即就是，每条连接线24的一端可以与位于透光显示区211内的一个第一发光器件22耦接，另一端可以与位于常规显示区212内的一个第一像素驱动电路23耦接。这样，每个第一发光器件22可以通过一条连接线24与一个第一像素驱动电路23耦接。
可选地，多个第一发光器件22中的至少两个第一发光器件22可以通过至少两条连接线24与多个第一像素驱动电路23中的一个第一像素驱动电路23耦接。即就是，至少两条连接线24的一端可以与位于透光显示区211内的至少两个第一发光器件22一一对应耦接，至少两条连接线24的另一端可以与位于常规显示区212内的一个第一像素驱动电路23耦接。这样，多个第一发光器件22可以通过多条连接线24与一个第一像素驱动电路23耦接。一个第一像素驱动电路23可以驱动多个第一发光器件22。
或者，多个第一发光器件22中的一个第一发光器件22可以通过至少两条连接线24与多个第一像素驱动电路23中的至少两个第一像素驱动电路23耦接。 这样，第一发光器件22可以通过多条连接线24与多个第一像素驱动电路23耦接。多个第一像素驱动电路23可以驱动一个第一发光器件22。
在一种可选地实施例中，如图6所示，至少一条连接线24可以包括第一走线241，第一走线241可以包括位于透光显示区211内的第一线段2411和位于常规显示区212内的第二线段2412，第一线段2411可以和第二线段2412连接，第一线段2411可以与第一发光器件22耦接，第二线段2412可以与第一像素驱动电路23耦接，第一线段2411和第一方向f1之间的夹角α可以大于0度且小于90度。或者，进一步的，第一线段2411和第一方向f1之间的夹角大于30度且小于70度。如此可以通过设置第一线段2411和第一方向f1之间的夹角α的值，灵活排布多条第一线段2411，使得显示面板上的多条第一线段2411的排布方式较为灵活。
可选地，第一走线241的第一线段2411和第一方向f1之间的夹角可以为45度。可以使得位于透光显示211中的多条第一走线241的第一线段2411的布线较为均匀且规整。
可选地，第一走线241的第一线段2411和第一走线241的第二线段2412之间的夹角β可以大于90度。示例性的，第一走线241的第一线段2411和第一走线241的第二线段2412之间的夹角β可以为145度。如此，可以使得位于常规显示区212中的第二线段2412能够沿远离透光显示区211的方向延伸，以与位于常规显示区212中的第一像素驱动电路23耦接。
在一种可选地实施例中，第一走线241还可以包括位于透光显示区211内的第三线段2413，第三线段2413的一端可以与第一线段2411耦接，第三线段2413的另一端与第一发光器件22耦接。由于多条第一线段2411可以在透光显示区211中沿垂直于第一线段2411的方向上平行排布，且与多条第一线段2411耦接的多个第一发光器件22在第一线段2411的延伸方向上可以排列为一行，因此，沿垂直于第一线段2411的方向上平行排布的多条第一线段2411与耦接的多个第一发光器件22之间的距离不同。可以通过多条第三线段2314将多条第一线段2411和多个第一发光器件22一一对应地耦接，以避免多条第一线段2411在垂直于衬底21的方向上重叠。其中，第三线段2413可以沿第二方向f2延伸。
其中，第二线段2412可以沿第一方向f1延伸，第一方向f1可以和第二方向f2交叉，进一步地，第一方向f1可以和第二方向f2垂直。
可选地，如图6所示，与多组第一发光器件22a中的一组发光器件22a中的多个第一发光器件22耦接的第三线段2413的长度，与第三线段2413和透光显示区211的边缘的最短距离正相关。即沿从透光显示区211的中心至透光显示区211的边缘的方向上，第三线段2413的长度越来越短。
可选地，如图6所示，至少一条连接线24还可以包括第二走线242，第二走线242位于透光显示区211中的至少部分线段与第一方向f1平行。即位于透光显示区211中的多个第一发光器件22耦接的多条连接线24可以包括至少部分线段的延伸方向与第一方向f1具有锐角夹角α的第一走线241，还可以包括至少部分线段的延伸方向与第一方向f1平行的第二走线242。可以进一步提高位于透光显示区211的第一发光器件22对应的连接线24布线的灵活性，并且，第二走线242可以布置在未布置第一走线241的走线空间中，可以进一步合理地利用显示面板20上透光显示区211中的走线空间。
示例性的，如图7所示，图7是本申请实施例提供的一种透光显示区的结构示意图。位于透光显示区211中的多个第一发光器件22对应的多条连接线24，可以从透光显示区211的边缘处延伸出透光显示区，由图7可知，透光显示区211的边缘的一周上均可以排布有连接线24，可以使得透光显示区211中的布线空间的利用率较高。
可选地，如图8所示，图8是图7所示的显示面板中位于透光显示区的第一发光器件的结构示意图。位于透光显示区211内的多个第一发光器件22中，至少两个相邻的第一发光器件22与连接线24的连接位置在第二方向f2上可以具有指定距离。
示例性的，两个相邻的第一发光器件22与连接线24的连接位置分别为第一连接位置K1和第二连接位置K2，与上述两个相邻的第一发光器件22相邻的一个发光器件的连接位置可以为K3，第一连接位置K1和第二连接位置K2在第二方向f2上具有指定距离D1，第三连接位置K3和第二连接位置K2在第二方向f2上也具有指定距离D1，其中，第二方向f2可以与第一方向f1垂直，则连接两个相邻的第一发光器件22的连接线24的走线空间可以为第二连接位置K2和第三连接位置K3之间的距离D2。
如图9所示，图9是一种第一发光器件的结构示意图，两个相邻的第一发光器件22与连接线24的连接位置在第二方向f2上的距离为零，则连接两个相邻的发光器件22的连接线24的走线空间可以为第二连接位置K2和第三连接位 置K3之间的距离D3。相较于图5中的发光器件对应的连接位置的设置情况，D2大于D3，即就是本申请实施例中的发光器件22之间的连接线24的走线空间较大。
如此，可以在多条连接线24中至少一条连接线24位于透光显示区211内的至少部分线段的延伸方向与第一方向f1之间具有锐角夹角α的情况下，使得位于透光显示区211中的连接线24的走线空间较大。
在一种可选地实施例中，如图10所示，图10是本申请实施例提供的一种分区示意图。透光显示区211可以具有多个透光分区2111，透光分区2111中具有多个第一发光器件22，多个透光分区2111的面积相同，且多个透光分区2111围绕透光显示区211的中心设置。透光分区2111中与第一发光器件22耦接的至少一条连接线24由透光显示区211的中心向透光显示区211的边缘延伸。
如此，可以使得多个透光分区2111中的第一发光器件22的数量基本一致，从而可以使得多个透光分区2111中的第一发光器件22对应的连接线24的长度的差值较小，进而可以使得透光显示区211的多个透光分区2111中的第一发光器件22的亮度均匀，以提高透光显示区211的显示效果。
示例性的，透光显示区211可以具有4个透光分区2111，透光分区2111的形状可以为三角形或扇形。当透光显示区211的形状为矩形时，透光分区2111的形状可以为三角形；当透光显示区211的形状为圆形时，透光分区2111的形状可以为扇形。多个透光分区2111可以围绕透光显示区211的中心设置，该中心可以指透光显示区211的两对角线交点或者圆心。
可选地，如图10所示，透光分区2111可以包括由透光显示区211的中心和透光显示区211的边缘的连线s2划分的第一子分区211x和第二子分区211y，即第一子分区211x和第二子分区211y相邻。
位于第一子分区211x中第一发光器件22的连接线24与位于第二子分区211y中的第一发光器件22的连接线24的延伸方向不同。示例性的，位于第一子分区211x中第一发光器件22的连接线24与至少一行第一发光器件22的第一方向f1之间具有锐角夹角α，位于第二子分区211y中第一发光器件22的连接线24与至少一行第一发光器件22的第一方向f1之间也具有锐角夹角α，则位于第一子分区211x中第一发光器件22的连接线24与位于第二子分区211y中的第一发光器件22的连接线24之间的夹角可以为2α。
可选地，如图10所示，透光显示区211的中心和透光显示区211的边缘的 连线s2为透光分区2111的对称轴，如此，透光分区2111中的第一子分区211x和第二子分区211y的面积可以相同，可以使得第一子分区211x和第二子分区211y中的发光器件22的数量基本一致，从而可以使得第一子分区211x和第二子分区211y中的发光器件22对应的连接线24的长度的差值较小，进而可以使得透光显示区211的第一子分区211x和第二子分区211y中的发光器件22的亮度均匀，以提高透光显示区211的显示效果。
对称轴与第一方向f1平行或者垂直。透光显示区211中可以具有多个透光分区2111，多个透光分区2111的多个对称轴可以相互平行或者垂直，如此，可以使得透光显示区211中的走线24的布局较为规整。
可选地，如图7所示，透光分区2111可以包括平行连接区C1和位于平行连接区C1远离中心一侧的斜向连接区C2。位于平行连接区C1内的至少一个第一发光器件22可以与第二走线242耦接，位于斜向连接区C2内的至少一个第一发光器件22可以与第一走线241耦接。多个第一发光器件22中靠近透光显示区211的中心的第一发光器件22可以与第二走线耦接。
可以理解的是，透光分区2111可以包括第一子分区211x和第二子分区211y，以及透光分区2111可以包括平行连接区C1和斜向连接区C2，为透光分区2111的两种划分方式，这两种划分方式可以同时存在透光分区2111中。示例性的，第一子分区211x可以包括第一平行连接区和第一斜向连接区，第二子分区211y可以包括第二平行连接区和第二斜向连接区。
由图7可知，位于斜向连接区C2中的第一发光器件22连接的第一走线241由透光显示区211的中心向透光显示区211的边缘延伸，如此，透光分区2111中的对称轴附近可以存在部分区域未布置斜向连接线，如图7中的区域E1，区域E1可以用于布置平行连接区C1中的第一发光器件22连接的第二走线242。如此，可以合理利用透光显示区211中的走线空间，相对于单一方向的走线，可以在相同的透光显示区的211下，排布更多的连接线24。
可选地，请参考图11、图12、图13和图14，图11是本申请实施例提供的另一种显示面板的结构示意图，图12、图13和图14是本申请实施例示出的另外三种透光显示区的结构示意图。需要说明的是，图12、图13和图14中为了便于表示每一个结构层的连接线连接的第一发光器件的位置，将不同层的连接线分为三幅示意图示出。多个第一发光器件22可以包括多组第一发光器件22a，多组第一发光器件22a中的每组第一发光器件22a可以沿第三方向f3延伸，且 多组第一发光器件22a可以沿第四方向f4排布，第一方向f1、第二方向f2、第三方向f3和第四方向f4可以不重合。
多组第一发光器件22a中的一组第一发光器件22a可以包括沿第三方向f3排布的至少两个发光单元，发光单元可以包括至少一个第一发光器件22，至少两个发光单元可以分别与位于不同层的连接线24耦接。
需要说明的是，本申请实施例中以至少两个发光单元包括第一发光单元22a1、第二发光单元22a2和第三发光单元22a3为例进行说明，至少两个发光单元还可以具有其他的发光单元，本申请实施例对此不进行限制。其中，第一发光单元22a1、第二发光单元22a2和第三发光单元22a3的连接的多条第一走线241可以分别为第一连接线组24a，第二连接线组24b以及第三连接线组24c，第一连接线组24a，第二连接线组24b以及第三连接线组24c分别位于衬底上的不同层。
可以按照第一发光单元22a1、第二发光单元22a2和第三发光单元22a3的顺序，分别布置其对应的第一连接线组24a，第二连接线组24b以及第三连接线组24c，第一连接线组24a，第二连接线组24b以及第三连接线组24c中的连接线可以为第一连接线241。如此，可以增加连接线24的走线空间，使位于不同层的连接线24可以具有各自的走线空间，相较于单层布线的布线方式，可以在有限的空间写布置较多的连接线24。
如图12所示，在布置有第一连接线组24a的一层布线空间中，透光分区2111中的对称轴s2附近可以存在部分区域E2未布置第一连接线组24a，该部分区域E2可以用于布置透光分区2111中的第二走线242。同理，如图13所示，在布置有第二连接线组24b的一层布线空间中，透光分区2111中的对称轴s2附近可以存在部分区域E3未布置第二连接线组24b，该部分区域E3可以用于布置透光分区2111中的第二走线242。如图14所示，在布置有第三连接线组24c的一层布线空间中，透光分区2111中的对称轴s2附近可以存在部分区域E4未布置第三连接线组24c，该部分区域E4可以用于布置透光分区2111中的第二走线242。
其中，上述各部分区域的面积大小为：E2＞E3＞E4。如此，部分区域E2中可以布置较多的第二走线242。
在一种可选地实施例中，如图7和图8所示，图8所示的第一发光器件22为图7所示的显示面板中的多个第一发光器件22中的8个第一发光器件22，透 光显示区211的形状可以为圆形，第一发光器件22的形状可以为矩形，或者说第一发光器件22所在的像素单元的形状为矩形，且该矩形的长宽比可以为2：1，矩形的长边垂直于第一方向f1。需要说明的是，本申请实施例中的第一发光器件22的形状还可以为六边形、梯形、椭圆以及圆形中的至少一种。一个第一发光器件22所在的像素单元的形状可以为矩形，图13中的矩形可以表示第一发光器件22所在的像素单元的形状，也可以表示第一发光器件22的阳极的形状，黑色圆点可以用于表示第一发光器件22和连接线24的连接位置，本申请实施例中为了便于表示第一发光器件22和连接线24的排布情况，在至少部分附图中以第一发光器件22和连接线24的连接位置(即黑色圆点)表示第一发光器件22。相邻的两个第一发光器件22与连接线24的连接位置在第二方向f2上可以具有指定距离X，相邻的两个第一发光器件22与连接线24的连接位置在第一方向f1上的距离为Y，则相邻的两个第一发光器件22分别与连接线24的连接位置之间的连线距离为Z，Z等于X加Y的和的平方根。如此，位于斜向连接区C2的第一发光器件22耦接的连接线24的走线空间可以为Z，相较于相关技术中走线空间为X或者Y，可以使得连接线24的走线空间较大，并且，透光显示区211中的多个第一发光器件22耦接的多条连接线24可以位于不同层，可以进一步增大连接线24的走线空间。
由于透光显示区211中的走线空间会限制连接线24的数量，从而会限制连接线24对应的发光器件22的数量，进一步会限制透光显示区211的面积(在发光器件22的排布密度不变的情况下，发光器件22的数量越多，透光显示区211的面积越大)。因此，上述连接线24分层设置以及连接线24沿多个方向延伸的布线方式可以使得透光显示区211中具有更多的布线空间，可以布置数量较多的连接线24，从而可以设置较多的第一发光器件22，进而解压使得透光显示区211的面积较大。
示例性的，在458ppi像素空间下(发光器件的尺寸为27.675μm×55.35μm)，当透光显示区211中的第一发光器件22仅采用平行于第一方向f1的连接线24耦接位于透光显示区211两侧的第一像素驱动电路23时，可以在第一方向f1上设置42列第一发光器件22，其对应的透光显示区211的直径为2.325mm。当透光显示区211中的发光器件22对应的连接线24包括斜向连接区C2中的第一走线241以及平行连接区C1中的第二走线242时，沿第一方向f1可以设置48列第一发光器件22，对应的透光显示区211的直径为3.757mm，本申请实施 例中的透光显示区的面积相较于仅采用平行于第一方向f1的连接线24的布线方式中的透光显示区的面积增加了61.5％。
可选地，如图15和图16所示，图15是本申请实施例提供的另一种透光显示区的布线示意图，图16是图15所示的透光显示区的连接结构示意图。该透光显示区211的形状可以为八边形。至少一条连接线24还包括第三走线243，第三走线243可以包括位于透光显示区211内的第四线段2431、第五线段2432和第六线段3433，以及位于常规显示区内212的第七线段2434，第四线段2431、第五线段2432、第六线段2433和第七线段2434依次连接，第四线段2431与第一发光器件22耦接，第七线段2434与第一像素驱动电路23耦接，第四线段2431和第一方向f1之间的夹角θ1大于0度且小于90度，第五线段2432和第一方向f1之间的夹角θ2大于0度且小于90度。可以使得透光显示区211中的连接线24具有较多的布线方式，可以提高透光显示区211中连接线24的布线的灵活性。
可选地，第四线段2431和所述第五线段之间的夹角θ3大于45度且小于135度。进一步地，第四线段2431和第五线段2432之间的夹角θ3可以为90度。如此，可以使得透光显示区211中的第三走线243的布线较为规整。
示例性的，请参考图16、图17和图18，图17是本申请实施例示出的另一种透光显示区的连线示意图，图18是本申请实施例示出的另一种透光显示区的连线示意图。需要说明的是，图16、图17和图18中为了清楚的示出多个第一发光器件22的连接方式，仅示出了透光显示区211中部分区域的连接线24的连接情况，其他的区域的连接方式与图示的连接方式相同。
图16、图17和图18中，将连接不同层连接线24的第一发光器件22分为三幅图示出，图16示出了位于第一结构层201的多条连接线24耦接的多个第一发光器件22，图17示出了位于第二结构层202的多条连接线24耦接的多个第一发光器件22，图18示出了位于第三结构层203的多条连接线24耦接的多个第一发光器件22。位于第一结构层201的多条连接线24可以包括第一走线241和第三走线243，位于第二结构层202的多条连接线24可以包括第一走线241和第三走线243，且与第二结构层中202的第一走线241耦接的第一发光器件22，可以位于与第一结构层201中的第一走线241耦接的第一发光器件22靠近透光显示区211的中心的一侧。与第二结构层中202的第三走线243耦接的第一发光器件22，可以位于与第一结构层201中的第三走线243耦接的第一发光器件22远离透光显示区211的中心的一侧。
位于第三结构层203的多条连接线24可以包括第一走线241，与第三结构层中203的第一走线241耦接的第一发光器件22，可以位于与第二结构层202中的第三走线243耦接的第一发光器件22远离透光显示区211的中心的一侧，且位于与第二结构层202中的第一走线241耦接的第一发光器件22靠近透光显示区211的中心的一侧。
如此，显示面板20的同一个结构层中可以包括多种走线，可以提高透光显示区211中的第一发光器件耦接的连接线24的排布灵活性。
在一种可选地实施例中，请参考图19和图20，图19和图20是本申请实施例提供的另外两种显示面板中第一发光器件的结构示意图。如图19所示，位于透光显示区内一行的多个第一发光器件22中，至少两个相邻的第一发光器件22与连接线的连接位置K在第二方向f2上可以具有距离D4，第二方向f2可以垂直于第一方向f1，并且连接位置K均位于第一发光器件22的角部。
如图20所示，图20示出了第一发光器件22与连接线24的连接位置K的另一种设置方式，连接位置K可以均位于第一发光器件22的角部。如此，可以使得相邻的两个第一发光器件22之间的连线距离较大，进而使得相邻的两个第一发光器件22之间的连接线的走线空间较大。需要说明的是，本申请实施例中的第一发光器件22与连接线24的连接位置K并不仅限于图8、图19和图20中所示的连接位置K的设置方式，连接位置K还可以其他的设置方式，本申请实施例对此不做限制。
可选地，如图10所示，常规显示区212可以具有围绕透光显示区211分布的且与多个透光分区2111一一对应的多个常规子分区2121，常规子分区2121与对应的透光分区2111相邻。
透光分区2111的至少部分边缘与对应的常规子分区2121的至少部分边缘重合。可以使得多个透光分区2111中的第一发光器件对应的连接线的长度较短。
可选地，如图4所示，位于常规显示区212中的多个第二发光器件26的排布密度与位于透光显示区211中的多个第一发光器件22的排布密度相同。该排布密度相同可以指常规显示区212的单位面积内排布的第二发光器件26的数量，与透光显示区211中的单位面积内排布的第一发光器件22的数量相同。
如此，可以使得常规显示区212和透光显示区211的像素密度或者图像分辨率相同。可以使得常规显示区212和透光显示区211的显示效果接近。
其中，每英寸像素密度(英文：Pixel per inch；简写：PPI)也可以称作像 素密度单位，所表示的是显示区域中每英寸所拥有的像素数量。因此PPI的值越高，显示画面的细节就会越丰富。
图像分辨率(英文：Image Resolution)指图像中存储的信息量。可以以每英寸像素密度(PPI)来衡量。图像分辨率越高，该图像所包含的像素就越多，图像就越清晰。
