【技术领域】
本发明涉及显示技术领域,具体而言涉及一种显示面板及其讯号线的修复方法。
【背景技术】
液晶显示装置包括相对设置的阵列基板、彩色滤光片基板以及填充于两基板之间的液晶层。其中,阵列基板上设置有大量的讯号线(例如扫描线和数据线)。但是在生产过程中,大量设置的讯号线总会因为一些生产缺陷造成断线,这时断线上的像素电极就不能得到正常的数据信号,从而形成液晶面板的显示缺陷,液晶显示面板出厂前都会考虑对缺陷进行修复,以降低生产成本。
目前的修复方法中,修复线与正常的讯号线通常会设置在不同层,并且两者交叉重叠。对断裂的讯号线进行修复时,通常会使用激光光束聚焦于两者交叉重叠处,在局部位置产生高温,使得讯号线与修复线熔融导通,进而数据信号可以通过修复线进行传递。然而,激光光束的能量会随着使用的时间而逐渐减少,当能量减少到一定程度时,容易出现无法有效的熔融讯号线与修复线导致修复失败或是交叉重叠处的界面阻抗过大的问题。
综上所述,有必要提供一种显示面板及显示面板讯号线的修复方法。

【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
图1是本发明显示面板的结构示意图。如图1所示,显示面板10包括阵列基板11、彩色滤光片基板12以及液晶层13。
其中,阵列基板11与彩色滤光片基板12相对设置,液晶层13夹持于两基板之间。
图2是图1所示的阵列基板的结构示意图。如图2所示,本实施例的显示面板10的阵列基板11包括:多条讯号线201、多条修复线202以及多个透明导电层(图未示)。
在本发明中,讯号线201泛指显示面板10的驱动配线,在本实施例中,讯号线201例如为阵列基板11上垂直相交设置的扫描线或数据线。
应理解,在本发明的其他实施例中,讯号线201可以为共通线。共通线是一种连通线,在液晶显示面板中不同层的导电图案层之间会设置绝缘层以发挥绝缘效果,但是当不同层的导电图案层之间需要电性连接时,比如像素电极与薄膜晶体管的漏极需要电性连接时,会于绝缘层中形成穿孔(接触孔),以使位于绝缘层上的像素电极得以通过穿孔搭接在薄膜晶体管的漏极上,连接像素电极与漏极的连接线即为一种共通线。
本发明实施例中,阵列基板11上进一步设置修复线202以对讯号线201进行修复。
图3是本发明显示面板中修复线设置的第一实施方式的示意图,图4是图3所示的修复线沿着AA方向的剖面示意图。
请参阅图3和图4,讯号线201和修复线202交叉设置且分别位于不同层,修复线202设置在讯号线201的上方,透明导电层203设置于讯号线201与修复线202交叉重叠处的上方。
图5是本发明显示面板中修复线设置的第二实施方式的示意图,图6是图5所示的修复线沿着AA方向的剖面示意图。
参阅图5和图6,在本实施例中,讯号线201与修复线202的位置关系不同与图3所示的实施方式不同,具体而言:
讯号线201设置在修复线202的上方,透明导电层203设置在讯号线201的上方。
在本发明中,讯号线201和修复线202的材质为铝或铜,透明导电层203为氧化铟锡(ITO,Indium
Tin Oxides)层或氧化铟锌(IZO,Indium Zinc Oxides)层。
进一步的,本发明的显示面板修复讯号线的工作原理为:当讯号线201发生断裂需要进行修复时,采用激光光束聚焦于透明导电层203,使透明导电层203进入融熔状态,由于透明导电层203的熔点低于讯号线201和修复线202的熔点,熔融状态的透明导电层203可以为讯号线201和修复线202起到预热功能。即使激光光束的能量随着时间的递减,讯号线201和修复线202也能实现有效的导通。
基于以上讯号线修复方式,本发明中,只需将透明导电层203设置于讯号线201和修复线202交叉重叠处的上方即可,对于讯号线201和修复线202的层次关系并没有严格限制。
图7是本发明显示面板讯号线的修复方法的流程图,图8是本发明显示面板讯号线的修复方法的示意图。结合图7和图8,本发明显示面板讯号线的修复方法包括以下步骤:
步骤S701:设置与讯号线801不同层的修复线802;
其中,讯号线801为显示面板中阵列基板上垂直相交设置的扫描线或数据线,也可以为共通线。讯号线801的材质为铝或铜。
在本实施例中,修复线802设置在讯号线801的上方。在其它实施例中,可将讯号线801设置在修复线802的上方。
步骤S702:在修复线802与讯号线801交叉重叠处的上方设置透明导电层803,透明导电层803的熔点低于讯号线801和修复线802的熔点;
其中,透明导电层803为氧化铟锡层或氧化铟锌层。
在本实施例中,透明导电层803设置在修复线802的上方。在其他实施例中,透明导电层803可设置在讯号线801的上方。
步骤S703:对断裂的讯号线801进行修复时,采用激光光束聚焦于透明导电层803,使透明导电层803进入融熔状态,以导通讯号线801与修复线802。
在步骤S703中,讯号线801发生断裂需要进行修复时,采用激光光束聚焦于透明导电层803上的激光修复点804,使透明导电层803在激光修复点804的部分进入融熔状态,由于透明导电层803的熔点低于讯号线801和修复线802的熔点,熔融状态的透明导电层803可以为讯号线801和修复线802起到预热功能。即使激光光束的能量随着时间的递减,讯号线801和修复线802也能实现有效的导通。
综上所述,本发明通过在修复线和讯号线重叠处增加一层较低熔点的透明导电层,在修复讯号线时,只需将激光光束聚焦于透明导电层,让透明导电层进入融熔状态,使得修复线和讯号线之间导通,进而增加修复成功的机率。
以上所述仅为本发明的实施例,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
