Description

液晶显示器
技术领域
本发明涉及液晶显示技术领域，特别涉及一种液晶显示器。
背景技术
随着电子技术的发展，平板显示器件得到了飞速的发展，如液晶显示器件、等离子体显示器件和OLED（Organic Light-Emitting Diode，有机发光二极管）显示器件。在平板显示器件当中，液晶显示器件由于其重量低、体积小、能耗低等优点，从而得到了广泛的应用。
现有技术中，液晶显示器件的液晶面板上设有走线区、显示区、多条穿过显示区和走线区的数据线、多条扫描线以及至少一条用于修补数据线断线的修补线。通常，修补线包括第一部分、第二部分和第三部分。所述第一部分设置在走线区与显示区之间，与数据线垂直；第二部分设置在显示区下方，与数据线垂直；第三部分设置在显示区右侧，用于连接第一部分和第二部分。而这种修补线的设置位置决定了其只能修补显示区的数据线的断线，不能修补走线区的数据线的断线。然而，上述修补线设置在走线区与显示区之间的原因是，走线区之外的数据线是由一层金属制程，而走线区内的数据线为了减小信号的传输损耗，采用两层金属制程。上述修补线可以同显示区的扫描线采用同一道光罩制程，而走线区内如果设置修补线的话，势必要另外增加一道光罩制程，从而大大增加了液晶显示器的生产成本。然而，走线区内如果不设置修补线，则无法完成走线区的数据线的断线修补。

附图说明
图1为本发明液晶显示器第一实施例的结构示意图。
图2为本发明液晶显示器第二实施例的结构示意图。
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参照图1，图1为本发明液晶显示器第一实施例的结构示意图。本实施例提供的液晶显示器包括印刷电路板10、数据驱动芯片20、扫描驱动芯片30和液晶显示面板。上述液晶显示面板包括一条修补线40、短路棒区50、多个数据线焊盘60、扫描线焊盘 (图未示)、走线区70、显示区80、多条扫描线90、多条穿过显示区80和走线区70的数据线82以及多条用于测试时连接短路棒区50的短路棒和数据线焊盘60的测试线100。上述数据驱动芯片20固定于一第一柔性电路板(图未示)上，上述第一柔性电路板分别与上述印刷电路板10和上述数据线焊盘60电连接。上述扫描驱动芯片30通过一第二柔性电路板(图未示)分别与上述印刷电路板10和扫描线焊盘电连接。所述数据线82的第一端与数据线焊盘60电连接，第二端延伸到显示区80的下方。走线区70内的数据线82采用两层金属制程，走线区70以外的数据线82采用一层金属制程。
上述修补线40包括与测试线100绝缘交叉的第一部分41、与数据线82的第二端绝缘交叉的第二部分42以及修补时连接第一部分41和第二部分42的第三部分43。上述修补线40的第一部分41、第二部分42及第三部分43可以采用同一道光罩制程，例如与扫描线90同时制程，这种情况下，上述三部分在修补时直接连接。上述三部分也可以采用不同光罩制程，例如第一部分41和第二部分42与扫描线90采用同一光罩制程，第三部分43与数据线采用同一光罩制程。此种情况下，上述三部分非直接连接，需要修补前或修补时打洞连接，使三部分在修补时处于连接的状态。在其他实施例中，上述修补线40的数量可以根据需要设置为两条以上。
本实施例中，当显示区80中的一条数据线82出现断点A或者走线区70中的一条数据线82出现断点B时，可通过laser修补机台将修补线40的第一部分41与断点对应的测试线100在二者的交叉处C连通，同时将该修补线40的第二部分42与断点对应的数据线82在二者的交叉处D连通，从而使得断点A或者B下方的数据线由修补线40提供数据信号。
相较于现有技术，本发明液晶显示器的修补线40包括与测试线100绝缘交叉的第一部分41、与数据线82的第二端绝缘交叉的第二部分42以及修补时连接第一部分41和第二部分42的第三部分43，不仅可以修补液晶显示面板的走线区70的数据线82，也可以修补液晶显示面板的显示区80的数据线82，而且上述修补线40与走线区70的数据线82在不同的位置，可与显示区80的扫描线90或者数据线82采用同一光罩制程，不需另外增加光罩制程，不会大大提高液晶显示器的生产成本。
结合参照图2，图2为本发明液晶显示器第二实施例的结构示意图。本实施例提供的液晶显示器还包括一空白测试线101、第一空白数据线焊盘61和第二空白数据线焊盘62，第一空白数据线焊盘61与空白测试线101电连接。修补线40的第一部分41与测试线100及空白测试线101绝缘交叉，第三部分43包括第一连接线43a、第二连接线43b、第三连接线43c、第四连接线43d和第五连接线43e；其中，第一连接线43a、第二连接线43b分别设置在第一柔性电路板内，第三连接线43c、第四连接线43d分别设置在印刷电路板10内，第一连接线43a通过第一柔性电路板连接在第一空白数据线焊盘61和第三连接线43c，第二连接线43b通过第一柔性电路板连接在第二空白数据线焊盘62和第四连接线43d，第三连接线43c通过印刷电路板10内的一信号放大器901连接第四连接线43d，第五连接线43e一端连接第二空白数据线焊盘62，另一端连接上述修补线40的第二部分42。修补时，将第一部分41与测试线100打通，同时将第一部分41与空白测试线101打通，将第二部分42与数据线82打通，从而使得第一部分41通过第三部分43与第二部分42连接，同时将测试线100上的数据信号通过修补线40输送至显示区80的数据线，以完成断线修补。
应当说明的，本实施例中，修补线40的第一部分41与空白测试线101,在修补时通过打洞连接，其他实施例中，也可在修补前就通过打洞连接，只要在修补时使修补线40的第一部分41和第二部分42通过第三部分43连接就可以了，在此不作进一步地限定。在其他实施例中，修补线40的数量可以根据需求设置为两条以上。
本实施例中，当数据信号修补线40的第一部分41传输至第三部分42的第三连接线43c后，通过印刷电路板10中的信号放大器11对数据信号放大后经第四连接线43d、第五连接线43e输出至修补线40的第二部分42，最终通过该第二部分42输出至数据线82。由于对数据信号进行放大，因此可有效防止因传输过程中由于数据信号的消弱导致显示区80的数据线出现弱线或无法显示等显示缺陷。
具体地，上述修补线40的第一部分41和第二部分42与扫描线90平行，第三部分43的第五连接线43e与数据线平行。本实施例可提高整体布局的美观，同时降低设计的难度。
本发明第三实施例的液晶显示器与第二实施例的液晶显示器大致相同，其区别之处在于：第三实施例的液晶显示器进一步包括至少一条显示区修补线，其用于修补显示区的数据线断线，所述显示区修补线包括第四部分、与数据线的第二端绝缘交叉的第五部分和修补时连接第四部分和第五部分的第六部分。所述第四部分设置于走线区和显示区之间，且与数据线绝缘交叉。所述显示区修补线充分利用走线区和显示区之间的空间，对显示区的数据线进行修补。
以上仅为本发明的优选实施例，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。
