Description

显示基板的修复电路和修复方法、显示基板和显示装置
相关申请
本申请要求享有2016年10月20日提交的中国发明专利申请No.201610913673.5的优先权，其全部公开内容通过引用并入本文。
技术领域
本申请涉及显示技术领域，具体而言，本申请涉及一种显示基板的修复电路和修复方法、包括修复电路的显示基板和包括显示基板的显示装置。
背景技术
显示基板已经广泛应用于各种显示装置。为了满足各种显示设备的高分辨率和/或小型化的需求，显示基板内部电路的电极宽度变得越来越窄，显示基板内部电路的电极断裂不良发生的可能性也越来越大。
对于薄膜晶体管液晶显示装置(TFT-LCD)而言，显示器件内部电路主要包括栅极电路、源极电路和公共电极。当源极电路在显示基板的显示区域内发生断裂时，通常可通过激光设备使用在显示基板内部预留的数据线断路(Data Open，DO)修复电路来进行维修。但是，当源极电路的引线部分在扇出(Fan out)区域发生断裂，即，发生引线断路(Lead Open，LO)时，则无法使用显示基板内部修复电路进行维修。
在相关技术中，当引线电路的断开位置位于液晶盒外时，可以采用面板焊盘修复(Panel Pad Repair，PPR)设备进行维修，但是当引线电路的断开位置位于液晶盒内的部分时，则无法维修。
对于发生在液晶盒内的引线电路的断裂，由于无法使用PPR设备进行维修，不良品只能做报废处理，因此降低了发生引线电路断裂的显示基板的可维修比率。此外，由于PPR设备需要在电极表面沉积钨粉，因而容易受到电极区域洁净度的影响，从而使得维修时间较长且维修成功率较低。
发明内容
本申请旨在提出一种用于显示基板的修复电路和修复方法，使得可以对发生在液晶盒内和液晶盒外的引线电路的断裂都能够进行维修。此外，本申请还提供了一种包括修复电路的显示基板和包括显示基板的显示装置。

附图说明
通过以下结合附图的详细描述能够更加清楚地理解本申请的构思，其中：
图1是示出了根据本申请的一个实施例的用于显示基板的修复电路的示意图；
图2是示出了根据本申请的另一实施例的用于显示基板的修复电路的示意图；以及
图3是用于说明利用根据本申请的实施例的修复电路对显示基板进行维修的示意图。
具体实施方式
下文中，将参照附图描述体现本申请构思的示例实施例。然而，本申请构思可按照许多不同形式实现并且不应理解为限于本文阐述的示例实施例。相反，提供这些示例实施例以使得本公开将是彻底和完整的，并且将把本申请构思完全传递给本领域普通技术人员。然而，应该理解，不存在将本申请构思局限于所公开的特定形式的意图，而是相反，本申请构思是要覆盖落入本申请构思的精神和范围内的所有修改形式、等同形式和替代形式。在附图中，为了使本申请构思清楚，夸大了结构的尺寸。
应该理解，本申请所使用的术语“和/或”包括相关所列项之一或多个的任何和所有组合。当诸如“……中的至少一个”的表达出现在元件的列表之后时，其修饰整个列表而不修饰列表中的单个元件。
另外，虽然在根据本申请构思的各个实施例中使用术语例如“第一”和“第二”来描述多个构件、组件、区、层和/或部分，但是这些 构件、组件、区、层和/或部分不应被这些术语限制。这些术语仅用于将一个构件、组件、区、层或部分与另一构件、组件、区、层或部分区分开。因此，在实施例中称作第一构件、第一组件、第一区、第一层或第一部分的构件、组件、区、层或部分也可称作第二构件、第二组件、第二区、第二层或第二部分，而没有脱离本申请的指教。
图1是示出了根据本申请的一个实施例的用于显示基板的修复电路的示意图。
如图1所示，显示基板100可以包括显示区DR和设置在显示区DR之外的引线区LR。用于显示基板100的修复电路200可以包括：第一修复线210，其设置在引线区LR远离显示区DR的一侧，并与引线区LR中的引线相交叉；第二修复线220，其设置在引线区LR靠近显示区DR的一侧，并与引线区LR中的引线相交叉；以及第三修复线230，其将第一修复线210连接至第二修复线220，其中，引线区LR中的引线与第一修复线210和第二修复线220电绝缘。
图2是示出了根据本申请的另一实施例的用于显示基板的修复电路的示意图。
如图2所示，根据本申请另一实施例的用于显示基板100的修复电路200′还可以包括：第四修复线240，其设置在显示区DR远离引线区LR的一侧，与设置在显示区DR的数据线相交叉并绝缘。第三修复线230将第一修复线210和第二修复线220连接至第四修复线240。
下面将参照图3对利用根据本申请的实施例的维修电路对显示基板进行维修进行说明。
图3是用于说明利用根据本申请的实施例的修复电路对显示基板进行维修的示意图。
参考图3，其示出了图2所示的用于显示基板100的修复电路200′。然而，本申请不局限于此，还可以利用图1所示的修复电路200对显示基板进行维修。此外，出于清楚的目的，在图3中对显示基板100的引线区LR进行了放大显示。应当认识到，在图3中示出的各个区域没有按比例绘制。
如图3所示，设置在引线区LR的引线L将数据信号提供至设置在显示区DR的数据线D。根据本申请的一个实施例，引线区LR可以包括集成电路焊接区BR和与集成电路焊接区BR相邻的扇出区FR。扇 出区FR可以设置在集成电路焊接区BR与显示区DR之间。第一修复线210可以设置在集成电路焊接区BR远离显示区DR的一侧，并且第二修复线220可以设置在扇出区FR与显示区DR之间。
根据本申请的一个实施例，设置在扇出区FR的引线L可以包括蛇形引线SL以及将蛇形引线SL连接至设置在显示区DR的数据线D的扇出线FL。
当设置在引线区LR的引线L发生断路时，例如在图3示出的A点位置引线L发生断路，可以使第一修复线210和第二修复线220分别与发生断路的引线L电连接，以通过第一修复线210、第二修复线220和连接至第一修复线210和第二修复线220的第三修复线230形成的导电路径修复发生断路的引线L。
虽然在图3中将发生断路的位置示出为断路发生在扇出线FL上，但是本申请不局限于此，发生断路的位置也可以是在蛇形引线SL上。当引线L的蛇形引线SL发生断路时，也可以应用以上描述的修复方式对发生断路的引线L进行维修。
根据本申请的一个实施例，可以通过激光熔接方法使第一修复线210和第二修复线220分别与发生断路的引线L电连接。通过激光使得设置在第一修复线210和第二修复线220与发生断路的引线L之间的绝缘层熔化，即，分别在第一修复线210和第二修复线220与发生断路的引线L的交叉点B1和B2处形成激光熔接位置。在所述激光熔接位置，第一修复线210和第二修复线220分别与发生断路的引线L电连接。
根据本申请的一个实施例，当设置在显示区DR的数据线D发生断路时，例如在图3示出的C点位置数据线D发生断路，可以使第四修复线240与发生断路的数据线D电连接，并且使第二修复线220与连接至发生断路的数据线D的引线L电连接，以通过第二修复线220、第四修复线240和连接至第二修复线220和第四修复线240的第三修复线230形成的导电路径修复发生断路的数据线D。
根据本申请的一个实施例，可以通过激光熔接方法使第四修复线240与发生断路的数据线D电连接，并且使第二修复线220与连接至发生断路的数据线D的引线L电连接。通过激光使得设置在第四修复线240与发生断路的数据线D之间的绝缘层熔化，并且使得设置在第 二修复线220与连接至发生断路的数据线D的引线L之间的绝缘层熔化，即，分别在第二修复线220与引线L的交叉点B2处和第四修复线240与数据线D的交叉点B3处形成激光熔接位置。在所述激光熔接位置，第二修复线220与引线L电连接，第四修复线240与数据线D电连接。
虽然未在附图中示出，但是设置在显示基板上的修复电路还可以包括放大电路。例如，当显示基板内部所采用的金属材料的电阻率较高或者显示基板的尺寸较大时，利用所述金属材料形成的修复电路的电阻较高，因而会对施加至显示基板的像素的信号产生影响。通过设置放大电路可以克服由于修复电路的高电阻所产生的影响。
虽然在附图中示出了在显示基板上设置有一条修复电路，然而本申请不局限于此。可以根据具体应用情况(例如，内部设置的放大电路所能够提供的线路数量以及/或者设置在显示基板周边的走线的密度)设置两条或更多条修复电路。
可以在包括显示区和设置在显示区之外的引线区的显示基板上应用根据本申请的修复电路，以便对发生在引线区的引线和/或显示区的数据线上的断路进行维修。
包括有根据本申请的修复电路的显示基板可以应用于各种显示装置，包括(但不局限于)计算机、超移动PC(UMPC)、工作站、上网本、PDA、便携式计算机、无线电话、移动电话、电子书、便携式多媒体播放器(PMP)、便携式游戏机、导航装置、黑盒子、数码相机、三维电视机、数字音频记录仪、数字音频播放器、数字图片记录仪、数字图片播放器、数字视频记录仪、数字视频播放器等任何包括有显示器的显示装置中。
根据本申请的另一个方面，提供一种利用根据本申请的修复电路对显示基板进行修复的方法。参照图3，所述修复方法包括：当设置在引线区LR的引线L发生断路时，例如在图3示出的A点位置引线L发生断路，使第一修复线210和第二修复线220分别与发生断路的引线L电连接，以通过第一修复线210、第二修复线220和连接至第一修复线210和第二修复线220的第三修复线230形成的导电路径修复发生断路的引线L。
根据本申请的实施例，可以通过激光熔接方法使第一修复线210 和第二修复线220分别与发生断路的引线L电连接。
参照图3，根据本申请的实施例，所述修复方法还可以包括：当设置在显示区DR的数据线D发生断路时，例如在图3示出的C点位置数据线D发生断路，可以使第四修复线240与发生断路的数据线D电连接，并且使第二修复线220与连接至发生断路的数据线D的引线L电连接，以通过第二修复线220、第四修复线240和连接至第二修复线220和第四修复线240的第三修复线230形成的导电路径修复发生断路的数据线D。
根据本申请的实施例，可以通过激光熔接方法使第四修复线240与发生断路的数据线D电连接，并且使第二修复线220与连接至发生断路的数据线D的引线L电连接。
在根据本申请的用于显示基板的修复电路和修复方法中，当设置在显示基板的引线区的引线发生断裂时，可以通过在显示基板内部预留的LO修复电路(其包括第一修复线至第三修复线)对发生断裂的引线进行维修，而无需考虑引线断路是否发生在液晶盒内或液晶盒外。因此，根据本申请的用于显示基板的修复电路和修复方法对发生在液晶盒内和液晶盒外的引线断路都能够进行维修。
虽然上面已经示出和描述了示例实施例，但是本领域技术人员应该清楚，在不脱离由所附权利要求限定的本申请构思的范围的情况下，可作出各种修改和改变。
