请继续参阅图3,预设连接点40包括多个第一子预设连接点401和多个第二子预设连接点402;其中,第一子预设连接点401沿信号线20的排布方向设置在第一部分301上,第二子预设连接点402沿信号线20的排布方向设置在第二部分302上。
需要说明的是,将第一子预设连接点401沿信号线20的排布方向设置在第一部分301中,以及将第二子预设连接点402沿信号线20的排布方向设置在第二部分302中,便于备用线30与处于断路的信号线20进行电性连接。
在一些实施方式中中,备用线30还包括用于连接第一部分301和第二部分302的连接部303,连接部303包括第一子连接部3031和第二子连接部3032,且第一子连接部3031和第二子连接部3032分别设置在多条信号线20的两侧。其中,第一子连接部3031、第二子连接部3032、第一部分301以及第二部分302在基板10上的投影至少部分覆盖信号线20。
当任一信号线20处于断路时,可以先采用如激光焊接的方法,使得处于断路的信号线20与备用线30电性连接,从而使得处于断路的信号线20正常工作。再通过激光切割法切割备用线30上对应所述处于断路的信号线20的切割点,以使得处于断路的信号线20通过备用线30正常工作。
例如,请参阅图4,图4为图3所示的OLED显示面板中一条信号线处于断线状态下的A部放大图。当一条信号线20处于断路时,将基板10转移至激光切割机上,并采用激光切割的方法切断备用线30上对应处于断路的信号线20的切割点60,然后再通过激光焊接,将处于断路的信号线20与备用线30连接。焊接时,激光首先会熔断备用线30上的预设连接点40,然后再在绝缘层50上形成过孔,备用线30通过过孔与信号线20进行电性连接,从而使得处于断路的信号线20与备用线30电性连接。最后,通过激光切割法切割备用线30上对应处于断路的信号线20的切割点60,该切割点60在基板10上的投影位于信号线20在基板10上的投影的一侧。
再例如,请参阅图5,图5为图3所示的OLED显示面板中两条信号线处于断线状态下的A部放大图。当有两条信号线20处于断路时,此时信号线205以及信号线206均处于断路。首先,还是将基板10转移至激光切割机上,并采用激光切割的方法切断备用线30上对应处于断路的信号线205的切割点601,以及采用激光切割的方法切断备用线30上对应处于断路的信号线206的切割点602,然后再通过激光焊接,将处于断路的信号线205与备用线30连接,同时将处于断路的信号线206与备用线30连接。焊接时,激光首先会熔断备用线30上的预设连接点40,然后再在绝缘层50上形成过孔,备用线30通过过孔与信号线205进行电性连接以及,备用线30通过过孔与信号线206进行电性连接,从而使得处于断路的信号线205以及处于断路的信号线206与备用线30电性连接。最后,再通过激光切割法切割所述备用线30上对应所述处于断路的信号线205的切割点601以及处于断路的信号线206的切割点602,其中,切割点601和切割点602在基板10上的投影位于信号线205和信号线206在基板10上的投影之间。
在一些实施方式中,备用线30还包括用于连接所述第一部分301和第二部分302的连接部304,所述连接部304位于所述多条信号线20的任一侧。
请参阅图6,图6为本申请提供的OLED显示面板的第二种实施方式的A部放大图。图6的OLED显示面板1与图3的OLED显示面板1的区别在于:备用信号线30为半环形结构。该备用线30包括第一部分301、第二部分302和用于连接第一部分301和第二部分302的连接部304。每条信号线20在基板10上的投影均与第一部分301和第二部分302相交,且第一部分301和第二部分302相对设置。连接部304位于多条信号线20的任一侧。
当任一信号线20处于断路时,可以先采用如激光焊接的方法,使得处于断路的信号线20与备用线30电性连接,从而使得处于断路的信号线20正常工作。
在一些实施方式中,请参阅图7,图7为图6所示的OLED显示面板中一条信号线处于断线状态下的A部放大图。需要说明的是,当仅有一条信号线20处于断路时,只需要对信号线20和备用线30进行焊接,而不需要对备用线30进行激光切割,可以进一步提高效率。
比如,当只有一条信号线20处于断路时,将基板10转移至激光切割机上,并采用激光切割的方法切断备用线30上对应处于断路的信号线20的切割点60,然后再通过激光焊接,将处于断路的信号线20与备用线30连接,焊接时,激光首先会熔断备用线30上的预设连接点40,然后再在绝缘层50上形成过孔,备用线30通过过孔与信号线20进行电性连接,从而使得处于断路的信号线20与备用线30电性连接,进而使得信号线20正常工作。
在一些实施方式中,信号线20的数量等于备用线30的数量的两倍。
因为一条备用线30最多可以修复两条处于断路状态的信号线20,因此,当信号线20的数量等于备用线30的数量的两倍时,即能保证每条信号线20都不会因断路而造成OLED显示面板的显示质量下降的问题,同时也便于备用线30的布线。
在一些实施方式中,多条备用线30设置在同一层,且相互绝缘。
在一些实施方式中,多条备用线30设置在不同层,且每条备用线30在基板10上的投影均重合。
当多条备用线30设置在不同层时,每条备用线30在所述基板10上的投影均重合,这样不仅可以防止相邻备用线之间发生串扰,提高了OLED显示面板的稳定性,并且由于每条备用线30均位于不同层,因此有利于实现窄边框的OLED显示面板。
请参阅图8,图8为本申请提供的OLED显示面板的第三种实施方式的A部放大图。当OLED面板中,有三条信号线20处于断路,则增加一条备用线30,备用线30与处于断路的三条信号线20的连接方法请参阅前面的实施例,在此不再赘述。
本申请通过在基板10上设置至少一条备用线30,当任一信号线20处于断路时,处于断路的信号线20可以通过备用线30正常工作,达到了提高OLED显示面板的显示质量的目的,进而提高了OLED显示面板的产品良率,并且还提高了OLED显示面板的出货率。
相应的,本申请还提供了一种OLED显示装置,其包括OLED显示面板1,该OLED显示面板包括基板10,以及设置在基板10上的多条信号线20和至少一条备用线30,信号线20与备用线30位于不同层。其中,备用线30在基板10上的投影与任一信号线20在基板10上的投影至少有两个重合点。OLED显示面板1的具体结构请参阅前面实施例,在此不再赘述。
以上对本申请提供的OLED显示面板以及显示装置进行了详细介绍,本文中应用了具体个例对本申请的原理及实施方式进行了阐述,以上实施例的说明只是用于帮助理解本申请。同时,对于本领域的技术人员,依据本申请的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本申请的限制。
