进一步的,所述多个开关组102可以沿所述第二方向02相互平行设置,可以节省所述非显示区10在所述第二方向02的空间。
需要注意的是,所述第一方向01、第二方向02为方便描述,就指代附图3-4中的箭头方向,即第一方向01为附图3-4中垂直向上的方向,第二方向02为附图3-4中水平向右的方向,但是在本发明的实施例中,第一方向01、第二方向02只要满足相互垂直即可,方向并不限制于附图3-4中的方向。

可以理解的,在图3-4的实施例中,在所述像素组200包括一个所述第一像素201和一个所述第二像素202的前提下,由于同一所述像素组200中的第一像素201和第二像素202上下分排设置,对于同一所述像素组200而言,可以使得所述第一像素201和所述第二像素202的分布更加均匀,提高显示面板的显示的均匀度。

可以理解的,如图4所示,本实施例与图3的实施例一其中区别在于,所述第一开关1021和所述第二开关1022是相互独立设置的,没有共用同一个所述输入端;因此本实施例中所述第一开关1021中的第一输入端1041、第一输出端1042的相对位置以及所述第二开关1022中的第二输入端1043、第二输出端1044的相对位置不做限制,只需满足所述第一输入端1041、第一输出端1042分别位于第一控制端1045两侧,以及所述第二输入端1043、第二输出端1044分别位于第二控制端1046两侧即可。

可以理解的,图4的实施例和图3的实施例相比较,虽然开关组102的制备上成本较高、并且占用的非显示区100的水平空间较多;但是对于所述开关组102与对应的像素组200连接关系而言,大大简化,可以提高光罩的制备效率以及减少走线的成本。
综合以上实施例可知,本方案中测试信号的信号流如下:
所述第一测试信号依次通过所述第一信号线1011、所述第五传输线1035、所述开关组102的第一开关1021的第一输入端1041,以及所述第三测试信号依次通过所述第三信号线1013、所述第六传输线1036、所述开关组102的第一开关1021的第一控制端1045;以至于在所述开关组102的第一开关1021的第一输出端1042输出电信号,以对对应的像素组200的第一像素201进行性能测试。

当所述第一开关1021和所述第二开关1022中至少一个的本质为薄膜晶体管时,在一实施例中,如图6所示,为所述显示面板00的截面图,所述显示面板00的包括衬底层301、遮光层302、缓冲层303、栅极绝缘层304、有源层305、层间绝缘层306、栅极层307以及源极层308、漏极层308。

其中,所述源极层308、漏极层308可以在同层采用相同的材料制备。
可以理解的,所述栅极层307为图案化形成的膜层,结合图3,所述栅极层307可以包括多个所述第一控制端1027和多个所述第二控制端1028;所述源极层308、漏极层308可以为一次性图案化形成的膜层,结合图3,所述源极层308、漏极层308可以包括多个所述输入端1023、多个所述第一输出端1026和多个所述第二输出端1029。
同理,结合图4,所述栅极层307可以包括多个所述第一控制端1045和多个所述第二控制端1046;所述源极层308、漏极层308可以为一次性图案化形成的膜层,结合图4,所述源极层308、漏极层308包括多个所述第一输入端1041、多个所述第二输入端1043、多个所述第一输出端1042和多个所述第二输出端1044。
可以理解的,如图3所示,由于所述第一控制端1027
和所述第二控制端1028需要与所述第二传输线10312、所述第四传输线10322连接,因此,可以将所述第一控制端1027、所述第二控制端1028、第二传输线10312、第四传输线10322采用同一种导电材料制备,即可以一体成型;如图4所示,由于所述第一控制端1045和所述第二控制端1046需要与所述第六传输线1036、所述第八传输线1038连接,因此可以将所述第一控制端1045、所述第二控制端1046、第六传输线1036以及第八传输线1038采用同一种导电材料制备,即可以一体成型。
同理,如图3所示,由于所述输入端1023需要与所述第一传输线10311、部分的第三传输线10321连接,因此,可以将所述输入端1023、第一传输线10311、部分的第三传输线10321采用同一种导电材料制备,即可以一体成型;如图4所示,由于所述第一输入端1041、第二输入端1043需要与所述第五传输线1035、部分的第七传输线1037连接;因此,可以将所述第一输入端1041、第二输入端1043、第五传输线1035、部分的第七传输线1037采用同一种导电材料制备,即可以一体成型。
在一实施例中,如图3-4所示,所述第一信号线1011、第二信号线1012以及第三信号线1013由于没有交集,可以同层采用相同的材料制备。
需要注意的是,所述信号线组1014内的信号线、所述传输线组103内的传输线以及用于连接所述开关组102与所述像素组200之间连接线在制备上应该遵循:在线路交叉处的两条或者多条导线应该在不同层进行制备,避免在同层制备导致交叉的导线相互连通,干扰信号传输;进一步的,为了减少制备导线的层数,可以分成两层制备上述导线,且两层采用不同材料制备上述导线,确保交叉处的导线的层数以及材料不同即可。
