Description

显示面板的修补线路及其修补方法 技术领域
本发明是有关于一种显示面板的修补线路及其修补方法,且特别是有关于一种用于改善信号线的电阻电容延迟(RC-delay)的显示面板的修补线路及其修补方法。
背景技术
图1为现有液晶显示面板修补信号线的示意图。如第1图所示,一液晶显示面板包含有一基板10,于基板10上具有若干条扫描线12及若干条信号线14,并且所述若干条扫描线12彼此平行且与所述若干条信号线14交错。所述扫描线12以及所述信号线14之间形成若干个画素区域,并各透过一薄膜晶体管(Thin Film Transistor, TFT)(未图示)控制画素的更新。另外,于基板10上还具有一扫描芯片22及若干个信号芯片24,于图式中为清楚说明仅以一个信号芯片24表示。所述扫描芯片22用于依序的驱动所述扫描线12、所述信号芯片24是用于提供画素的显示信号给所述信号线14。
由于画素数量的提高,在基板10上的相邻的扫描线12或是相邻信号线14之间仅有数微米的间隔。因此在制作过程中,可能会因为异物(例如尘埃)造成信号线14断开。为解决信号线14断开的问题,现有的液晶显示面板还会在基板10上设置用于修补断开信号线的修补线(rescue line)16。修补线16设置于该些扫描线12及信号线14所形成的显示区域11外围,并与若干信号线14交错并间隔一绝缘层。当某一信号线14发生断开的情形时,修补线16可利用与该信号线14重迭处(以黑点表示)进行激光焊接(laser welding)以修复信号线14断开的后半部。而信号芯片24所提供的显示信号则通过修补线16经由路径162来向断开的信号线14提供信号。
请参照图1及图2A,图2A为图1中A、B点的未修正的显示信号图。比较图1在同一水平线上的A、B两点:因为在A点的信号线14断开,故需要通过修补线16走路径162来传递显示信号至A点;而在B点的信号线14正常无断线,故信号直接走路经142由上往下传递。随着面板尺寸日渐增加,扫描线12及信号线14的数量越来越庞大,使得经由路径162传递至A点较经由路径142传递至B点长,并且有较大的电阻电容延迟(RC-delay)。因此A点较B点的显示信号失真的较为严重。然而,当显示信号差异太大时会导致在A点的充电率(charging ratio)较B点小很多,而在A点附近有弱线(weak line)的状况产生。
请参照图1及图2B,图2B为图1中A、B点的修正后的显示信号图,其中A点及B点的显示信号分别以以虚线及实线表示。在现有技术中,通常会在修补线16上设置一缓冲放大器(buffer amplifier)20电路以改善A点信号线的RC-delay情况,如图2B所示。同时也可解决A点附近弱线的问题。
然而,请参照图1及图3,图3为图1中C、D点的显示信号图,其中C点及D点的显示信号分别以实线及虚线表示。比较图1在同一水平线上的C、D两点:C点位于信号线14开路处的前段,而D点所处的信号线14正常,因此C点的RC-delay会较D点处小很多,当显示信号差异太大时,在C点附近也会有弱线(与D点所处之信号线差异过大)的状况产生。
技术问题
本发明的目的在于提供一种显示面板的修补线路,用以解决上述问题。
本发明的另一目的在于提供一种显示面板的修补线路的修补方法,用于修补断开的信号线,并且使修补后的信号线无弱线问题。
技术解决方案
为达上述的目的,本发明提供了一种显示面板的修补线路,所述显示面板包括若干条信号线,每一所述信号线具有一信号输入端及一信号末端。所述修补线路包括一放大器、一第一线路、一第二线路及一第三线路。所述放大器具有一输入端及一输出端。所述第一线路绝缘交错于所述若干条信号线的所述信号输入端,并电性连接于所述输入端。所述第二线路绝缘交错于所述若干条信号线的所述信号输入端,并通过一电阻电性连接于所述输出端。所述第三线路绝缘交错于所述若干条信号线的所述信号末端,并电性连接于所述输出端。
在本发明修补线路的较佳实施例中,所述放大器为一缓冲放大器,且所述放大器及所述电阻设置于一印刷电路板上。此外,所述第二线路电性连接于第三线路。值得一提的是,所述第一及第二线路与所述若干条信号线之间设有一绝缘层,并且所述第三线路与所述若干条信号线之间同样设有一绝缘层。值得注意的是,所述第一线路及所述第二线路相距有一间隔,以供切断所述若干条信号线。
根据本发明的显示面板的修补线路,所述第一线路以及第三线路结合所述放大器具有减少断路的信号线下半部的RC-delay情况。此外,所述第二线路设有所述电阻可衰减传递至断开的信号线上半部的显示信号,因此克服了上述的弱线问题。
除此之外,本发明还揭露一种显示面板的修补线路的修补方法。其中所述显示面板包括若干条信号线,每一所述信号线具有一信号输入端及一信号末端。所述修补线路包括一放大器、一第一线路、一第二线路及一第三线路。所述放大器具有一输入端及一输出端。所述第一线路绝缘交错于所述若干条信号线的所述信号输入端,并电性连接于所述输入端。所述第二线路绝缘交错于所述若干条信号线的所述信号输入端,并通过一电阻电性连接于所述输出端。所述第三线路绝缘交错于所述若干条信号线的所述信号末端,并电性连接于所述输出端。
所述修补方法包括:进行一焊接工艺,用以焊接一断路的信号线于对应的所述第一线路、所述第二线路及所述第三线路的交错处;以及进行一切割工艺,用以切断所述断路的信号线位于所述第二线路及所述第三线路的交错处的相连。所述焊接工艺优选是使用激光焊接;所述切割工艺优选是使用激光切割。
有益效果
根据本发明的修补线路的修补方法,断路的信号线的显示信号可由第一线路传递至所述放大器,并通过所述第三线路传递至所述断路的信号线的下半部,以减少断路的信号线下半部的RC-delay情况。所述显示信号经由所述放大器及第二电路传回至所述断路的信号线上半部,即所述显示信号通过所述电阻的衰减,使得断路的信号线上半部较周围的信号线相似,藉此解决弱线的问题。

本发明的最佳实施方式
请参照图4,图4为本发明较佳实施例的显示面板的修补线路的示意图。本较佳实施例的显示面板包括一基板10,于基板10上具有若干条扫描线(未图示)及若干条信号线14,并且所述若干条扫描线彼此平行且与所述若干条信号线14交错。所述扫描线以及所述信号线14之间形成若干个画素区域,并各透过一薄膜晶体管(Thin Film Transistor, TFT)(未图示)控制画素的更新。
每一所述信号线14具有一信号输入端146及一信号末端148,用以传输一显示信号。具体的说,于基板10上还具有若干个信号芯片24,于图式中为清楚说明仅以一个信号芯片24表示。所述信号芯片24是用于提供画素的显示信号给所述信号线14。
所述修补线路包括一放大器20、一第一线路30、一第二线路50及一第三线路70。所述放大器20具有一输入端202及一输出端204,用以传输所述显示信号。所述放大器20优选为一缓冲放大器(buffer amplifier)。所述缓冲放大器具有一很高的输入阻抗以及一很低的输出阻抗,以减少负载对信号源的影响。因此,所述显示信号可以通过所述缓冲放大器传递至所述第三线路以减少RC-delay情况。 所述放大器20优选是设置于一印刷电路板(PCB)21上,亦可设置在柔性电路板(FPC)上。
所述第一线路30绝缘交错于所述若干条信号线14的所述信号输入端146,并电性连接于所述放大器20的输入端202。所述第二线路50绝缘交错于所述若干条信号线14的所述信号输入端146,并通过一电阻26电性连接于所述输出端204。需注意的是,所述第一线路30及所述第二线路50与所述若干条信号线14之间设有一绝缘层(isolation layer) (未图示),例如二氧化硅(Silicon Deioxide),使得所述第一线路30与所述第二线路50相对于所述若干条信号线14的交错处(位于所述信号输入端146)是绝缘的。
所述第三线路70绝缘交错于所述若干条信号线14的所述信号末端148,并电性连接于所述输出端204,并且所述第三线路70与所述若干条信号线14之间同样设有一绝缘层(未图示),使得所述第三线路70相对于所述若干条信号线14的交错处(位于所述信号末端148)是绝缘的。此外,所述第二线路50电性连接于第三线路70于所述输出端204。在此较佳实施例中,所述第一线路30、所述第二线路50及所述第三线路70是同一金属材质,优选为易导电的金属,例如铜、铝、银、金等。
所述第一线路30及所述第二线路50相距有一间隔149,以供切断所述若干条信号线14。当其中有一条信号线14断线时,由于所述第二线路50设有所述电阻26可衰减传递至断开的信号线14上半部的显示信号,并保有原本通过所述缓冲放大器以减少断开的信号线14下半部的RC-delay情况,因此克服了上述的弱线问题。详细说明请叁考以下利用此较佳实施例的修补线路的修补方法。
请叁照图5,图5为图4的修补线路的修补后示意图。在本发明较佳实施例的显示面板的修补线路的修补方法,其中所述显示面板包括若干条信号线14,每一所述信号线14具有一信号输入端146及一信号末端148,用以传输由信号芯片24所提供的一显示信号242。所述修补线路包括一放大器20、一第一线路30、一第二线路50及一第三线路70。所述放大器20具有一输入端202及一输出端204,用以传输所述显示信号242。所述第一线路30绝缘交错于所述若干条信号线14的所述信号输入端146,并电性连接于所述输入端202。所述第二线路50绝缘交错于所述若干条信号线14的所述信号输入端146,并通过一电阻26电性连接于所述输出端204。所述第三线路70绝缘交错于所述若干条信号线14的所述信号末端148,并电性连接于所述的输出端20。
本发明的修补方法用于修补一断路的信号线14,特别以标号141表示。所述修补方法包括:进行一焊接工艺以及进行一切割工艺。所述焊接工艺用以焊接一断路的信号线141于对应的所述第一线路30、所述第二线路50及所述第三线路70的交错处,分别以标号31、51、71表示。所述焊接工艺优选是使用激光焊接(laser welding),贯穿上述的绝缘层使得断路的信号线141通过三个交错处31、51、71分别电性连接于所述第一线路30、所述第二线路50及所述第三线路70。
所述切割工艺用以切断所述断路的信号线141位于所述第一线路30及所述第二线路50的交错处31及51的相连,其中的切割处如图5中虚线所示。如前所示,所述第一线路30及所述第二线路50相距有一间隔149,使得第一线路30及所述第二线路50之间有足够空间以供切割。同样的,所述切割工艺优选是使用激光切割(laser cutting)。
经过如上修补后,断路的信号线141的显示信号242可由第一线路30透过交错处31传递至所述放大器20,如路径32所示。经过所述放大器20(例如一缓冲放大器)作用后的所述显示信号242则通过所述电阻26以及交错处51由第二电路50传回至所述断路的信号线141的上半部,如路径52所示。另外,经过所述放大器20作用后的所述显示信号242由第三电路70通过交错处71传递至所述断路的信号线141的下半部,如路径72所示。
请参照图6,图6为图5中C、D点的显示信号图,其中C点及D点的显示信号分别以实线以及虚线表示。经过所述放大器20作用后的所述显示信号242也有经过电阻26的作用而增加了RC-delay,使得在C点的显示信号较在D点的信号线14的显示信号相近,藉此解决在断路的信号线141的上半部的弱线的问题。另外,经过所述放大器20作用后的所述显示信号242在断路的信号线141的下半部能减少RC-delay的问题。
虽然本发明已用较佳实施例揭露如上,然其并非用以限定本发明,本发明所属技术领域中具有通常知识者,在不脱离本发明的精神和范围内,当可作各种的更动与润饰,因此本发明的保护范围当视后附的申请专利范围所界定者为准。
