在本实施例中，如图4所示，显示面板10还包括像素电路层13和透明导线层14，透明导线层14在显示面板10的厚度方向上位于像素电路层13与第一电极层127之间。
其中，像素电路层13包括多个第一像素电路131、多个第二像素电路132以及多条金属线133。第一像素电路131和第二像素电路132可以相同，也可以不同。第一像素电路131和第二像素电路132分别选自7T1C电路、6T1C电路、6T2C电路、5T1C电路、4T1C电路、3T1C电路以及2T1C电路中的一者。
如图4和图8所示，多个第一像素电路131位于过渡显示区10c，在过渡显示区10c，多个第一像素电路131聚集设置组成多个像素驱动电路岛131a，每个像素驱动电路岛131a包括至少两个第一像素电路131。
第二显示区10b的多个第二子像素124与多个第一像素电路131电性连接，且与多个第二子像素124电性连接的每个第一像素电路131与至少两个第二子像素124电性连接。具体地，与多个第二子像素124电性连接的每个第一像素电路131与至少两个发出相同色光的第二子像素124电性连接。例如，一个第一像素电路131与两个第二像素重复单元122中的两个第四发光单元124a电性连接，一个第一像素电路131与两个第二像素重复单元122中的四个第六发光单元124c电性连接，一个第一像素电路131与两个第二像素重复单元122中的两个第五发光单元124b电性连接。
透明导线层14包括多条透明导线141，一部分透明导线141位于第二显示区10b，另一部分透明导线141从过渡显示区10c延伸至第二显示区10b。多条透明导线141可以分一层设置，也可以分多层设置，多条透明导线141分多层设置时，位于不同层之间的透明导线141之间设置有绝缘层。多条透明导线141的制备材料为氧化铟锡或者氧化铟锌中的至少一种。
其中，位于第二显示区10b的至少部分透明导线141中的至少一条透明导线141的一端电性连接两个第二像素重复单元122中发出相同色光的至少两个第二子像素124，至少一条透明导线141的另一端与一个第一像素电路131电性连接，以电性连接一个第一像素电路131与两个第二像素重复单元122中发出相同色光的至少两个第二子像素124的同时，提高第二显示区10b的透光率。
在本实施例中，位于第二显示区10b的至少部分透明导线141的形状为蛇形，以抑制光穿过第二显示区10b时出现的衍射现象，进而改善第二显示区10b显示的显示效果。蛇形为非直线形，非直线形包括折线形、弧形曲线形等。
如图5所示，多个第一像素电路131也可以设置于第二显示区10b，多个第一像素电路131与多个第二子像素124电性连接。
如图4和图5所示，多个第二像素电路132位于第一显示区10a且设置于发光层12和基板11之间。多个第二像素电路132与多个第一像素重复单元121中的多个第一子像素123电性连接，以驱动多个第一子像素123发光。其中，一个第二像素电路132与一个第一子像素123电性连接。
多条金属线133位于过渡显示区10c且靠近第二显示区10b设置，多条金属线133围绕第二显示区10b设置，多条金属线133与第一像素电路131电性连接。多条金属线133为数据线。多条金属线133靠近第二显示区10b的外轮廓为过渡显示区10c与第二显示区10b之间的交界处。
如图8所示，过渡显示区10c包括靠近第二显示区10b的第一布线区10c1和靠近第二显示区10b的第二布线区10c2，第一布线区10c1位于第二布线区10c2之外，在第二显示区10b指向过渡显示区10c的方向上，多条金属线133在第一布线区10c1占用的尺寸大于多条金属线133在第二布线区10c2占用的尺寸。
由于第二电极层126在第二显示区10b的图案化设计是将红外激光从显示面板10的背面，即显示面板10的基板下方，照射至第二显示区10b的部分第二电极层126上，第二显示区10b的部分第二电极层126吸收红外激光，而显示面板中的有机层、无机绝缘层等对红外激光几乎无吸收，通过热弛豫和热传递使得该部分第二电极层126的温度升高，发生融化和气化等变化，使得该部分第二电极层126剥离，进而实现第二显示区10b的第二电极层126的图案化。
为了将整面的第二电极层126通过红外激光照射后制备得到图案化阴极1261和分布于图案化阴极1261中的多个透光开口1262，本申请通过在显示面板10的发光层12与基板11之间设置金属遮光层以遮挡部分红外激光，红外激光照射至第二显示区10b时，没有被金属遮光层遮挡的红外激光照射至部分阴极，该部分阴极去除，形成多个透光开口1262，进而实现第二电极层126的图案化。
如图4和图9所示，金属遮光层15在显示面板10的厚度方向上设置于发光层12与基板11之间，且金属遮光层15设置于像素电路层13与基板11之间。金属遮光层15包括多个第一遮光块151、一个第二遮光块152以及多条遮光连接线153。金属遮光层15的厚度为500埃-5000埃，例如为1000埃、1500埃、2000埃或者3000埃。金属遮光层15的制备材料选自钼、铝、钛、锂、钨、铜以及银中的至少一种。
如图4所示，多个第一遮光块151位于第二显示区10b且与图案化阴极1261重叠设置，至少部分第二像素重复单元122中的每个第二像素重复单元122对应一个第一遮光块151设置，每个第一遮光块151与对应的第二像素重复单元122至少部分重叠设置，以通过一个第一遮光块151对红外激光进行遮挡以对至少部分第二像素重复单元122中的每个第二像素重复单元122的多个第二子像素124进行保护。具体地，多个第二像素重复单元122中的每个第二像素重复单元122对应一个第一遮光块151重叠设置，且每个第二像素重复单元122的外轮廓与对应的第一遮光块151的外轮廓相同或趋于相同。
本申请将位于第二显示区10b的每个第二像素重复单元122中的多个第二子像素124进行聚拢设计，以减少每个第二像素重复单元122中的多个第二子像素124的共用阴极的面积，与此同时，增加相邻两个第二像素重复单元122之间的透光开口1262的面积，进而提高第二显示区10b的透光率。在每个第二像素重复单元122中的多个第二子像素124进行聚拢设计的基础上，一个第一遮光块151对应一个第二像素重复单元122设置，以使第二显示区10b的第二电极层126图案化而制备得到图案化阴极1261的同时，避免红外激光对每个第二像素重复单元122的组成部分造成损伤。
在本实施例中，对应一个第二像素重复单元122的多个第二子像素124重叠设置的多个第二阳极1272与对应一个第二像素重复单元122设置的一个第一遮光块151重叠设置，以避免红外激光图案化第二电极层126过程中，红外激光照射到对应一个第二像素重复单元122的多个第二子像素124重叠设置的多个第二阳极1272而对第二阳极1272造成损伤。
进一步地，对应一个第二像素重复单元122设置的多个第二阳极1272在基板11上的正投影位于一个第一遮光块151在基板11上的正投影内，且与一个第二像素重复单元122对应设置的一个第一遮光块151的外轮廓在基板11的正投影与对应一个第二像素重复单元122设置的多个第二阳极1272的外轮廓在基板11上的正投影之间的最小间距大于或等于0.5微米且小于或等于3微米，以在满足制程精度的条件下，使得一个第一遮光块151保护对应一个第二像素重复单元122的设置的多个间隔的第二阳极1272的同时，避免一个第一遮光块151的面积太大而导致图案化阴极1261的面积太大而不利于降低对光的透过率。例如，对应一个第二像素重复单元122设置的多个第二阳极1272的外轮廓在基板11上的正投影与对应的一个第一遮光块151的外轮廓在基板11的正投影之间的最小间距可以为1微米、1.5微米、2微米或者3微米。
进一步地，多个第一遮光块151的外轮廓均呈蛇形，以抑制第二显示区10b的衍射现象。
如图5所示，当多个第一像素电路131设置于第二显示区10b时，多个第一像素电路131与多个第一遮光块151重叠设置，以使多个第一遮光块151对多个第一像素电路131也起到保护作用。
如图9所示，第二遮光块152围绕多个遮光连接线153和多个第一遮光块151设置，第二遮光块152的至少部分设置于第二显示区10b的边缘，以使得红外激光图案化第二电极层126过程中，第二遮光块152对红外激光起到遮挡作用进而避免红外激光照射到位于过渡显示区10c且靠近第二显示区10b的多条金属线133而对多条金属线133造成损伤。
具体地，第二遮光块152从第二显示区10b延伸至过渡显示区10c，以在红外激光图案化第二电极层过程中，第二遮光块152对红外激光起到遮挡作用进而避免红外激光照射到靠近第二显示区10b边缘的金属线和第一像素电路131中的薄膜晶体管而对其造成损伤。位于过渡显示区10c的第二遮光块152也可以对像素电路岛131a设置，以起到对像素电路岛131a进行保护的作用。
需要说明的是，红外激光是线形光源且红外激光的能量呈高斯分布，红外激光边缘的能量较低而存在无法有效去除阴极的风险，为了保证第二显示区10b靠近过渡显示区10c的第二电极层126能完全去除，需要采用红外激光中能量较高的部分照射第二显示区10b靠近过渡显示区10c的第二电极层126，然而此时如果无金属层遮挡会导致红外激光边缘能量对过渡显示区10c中靠近第二显示区10b的金属线和薄膜晶体管造成损伤，故需要在过渡显示区10c设置第二遮光块152。同理，由于红外激光边缘能量的影响，为了避免红外激光图案化第二显示区10b的第二电极层的过程中对靠近第二显示区10b的金属线造成损伤，需要第二遮光块152从过渡显示区10c延伸至第二显示区10b。此外，由于第二遮光块152延伸至第二显示区10b，第二遮光块152对红外激光造成遮挡，使得第二电极层126未图案化的一部分也位于第二显示区10b。
如图4和图9所示，第二遮光块152具有位于第二显示区10b的第一边缘152a，第一边缘152a呈平滑的圆形，第一边缘152a距离第二显示区10b与过渡显示区10c之间的交界处的尺寸H大于或等于1微米且小于3微米，以满足制程精度的条件下使第二遮光块152对靠近第二显示区10b的多条金属线133进行保护的同时，避免第二遮光块152的面积太大而不利于提高第二显示区10b的透光率。
在第二显示区10b指向过渡显示区10c的方向上，第二遮光块152在第一布线区10c1的部分的尺寸大于第二遮光块152在第二布线区10c2的部分的尺寸，以使得第二遮光块152对第一布线区10c1的金属线133更好地保护。
具体地，如图9所示，第二遮光块152呈环形，第二遮光块152位于过渡显示区10c的第二边缘呈椭圆形，第二遮光块152位于第二显示区10b的第一边缘152a呈圆形，以使得第二遮光块152与多条金属线133的排布能匹配，进而对多条金属线133进行更好的保护。
进一步地，如图10所示，第一边缘152a呈蛇形，以进一步地抑制第二遮光块152的第一边缘152a对光的衍射现象。
第二遮光块152的宽度大于或等于10微米，以避免加工精度为10微米红外激光对过渡显示区10c中的多条金属线133造成损伤。
多条遮光连接线153位于第二显示区10b且与第二显示区10b的至少部分透明导线141重叠设置，多条遮光连接线153与图案化阴极1261重叠设置。红外激光图案化第二电极层过程中，多条遮光连接线153起到遮光作用，避免红外激光照射至至少部分透明导线141而对至少部分透明导线141造成损伤，避免影响第二显示区10b的第二子像素124的显示效果。具体地，多条遮光连接线153与位于第二显示区10b的多条透明导线141一对一重叠设置。
位于第二显示区10b的至少部分透明导线141在基板11上的正投影位于遮光连接线153的在基板11上的正投影内，且遮光连接线153的宽度与透明导线141的宽度的差值大于或等于0.5微米且小于或等于3微米，以满足制程精度的条件下使得遮光连接线153保护透明导线141的同时，避免遮光连接线153的宽度太大而不利于降低透光率。
遮光连接线153连接相邻两个第一遮光块151，且至少一个透光开口1262与相邻两个第一遮光块151和遮光连接线153围绕的区域重叠设置；和/或，遮光连接线153与相邻的第一遮光块151和第二遮光块152连接，至少一个透光开口1262与第一遮光块151、第二遮光块152以及遮光连接线153围绕的区域重叠设置，透光开口1262与金属遮光层15不重叠。
具体地，一部分遮光连接线153连接相邻两个第一遮光块151，相邻第一遮光块151以及连接相邻第一遮光块151的遮光连接线153围合的区域设置有镂空部154；另一部分遮光连接线153连接第二遮光块152和部分第一遮光块151，第二遮光块152、部分第一遮光块151以及部分遮光连接线153围合的区域也设置有镂空部154。
其中，多个镂空部154与多个透光开口1262重叠设置，一部分透光开口1262与一个第二遮光块152、与第二遮光块152相邻的部分第一遮光块151以及部分遮光连接线153围合的区域的镂空部154重叠设置，另一部分透光开口1262与相邻的第一遮光块151以及连接相邻第一遮光块151的部分遮光连接线围合的区域的镂空部154重叠设置。
进一步地，如图10所示，遮光连接线153的形状均为蛇形，从而进一步地抑制第二显示区10b的衍射现象，改善第二显示区10b的显示效果。
在本实施例中，基板11包括依次叠置的第一有机层、无机层以及第二有机层，第一有机层和第二有机层均为聚酰亚胺层，无机层为氮化硅层或氧化硅层中的至少一种。由于第一有机层和第二有机层中有离子，第二像素电路132工作过程中会产生电流，电流使离子极化，离子极化会产生电荷，电荷会影响第二像素电路132中的薄膜晶体管的电性能。
如图4、图9和图10所示，本实施例显示面板还包括多个屏蔽金属块16，多个屏蔽金属块16与金属遮光层15同层设置且对应多个第二像素电路132设置，每个屏蔽金属块16对应一个第二像素电路132中的至少一个薄膜晶体管设置，且每个屏蔽金属块16接入固定参考电压，以改善基板11中的离子极化影响第二像素电路132中的薄膜晶体管的电性能的问题。
多个屏蔽金属块16的厚度小于金属遮光层15的厚度，以保证金属遮光层15的遮光效果。
