请参阅图1,图1为本发明的具有触控结构的液晶显示器的部分电路图。如图1所示,该液晶显示器100包括集成电路(Integrated Circuit,IC)10及且与该集成电路10电性连接的触控结构30。该集成电路10为所述触控结构30提供其工作所需的功能信号,例如,在显示阶段,为该触控结构30提供恒压信号的电压信号;在触控阶段,为该触控结构30提供以该恒压信号为基准的脉冲信号。
该触控结构30位于所述集成电路10一侧,较佳地,在本发明的实施例中,该触控结构30靠近该集成电路10的一端定义为下端,远离该集成电路10的一端定义为上端。
该触控结构30包括触控区31及围绕该触控区31的外围区33。该触控区 31包括多个触控单元311及与该触控单元311对应的第一引线313。多个所述触控单元311呈阵列形排布,从而形成所述触控区31。该触控单元311包括若干列纵向排列的触控单元311,在本发明的较佳实施例中,以位于所述触控结构30两侧的两列触控单元311为例加以说明。
每一列中的触控单元311位于同一直线上,且均匀间隔地、从上端至下端依次排列于所述集成电路10的一侧,每一列中的触控单元311通过所述第一引线313与所述集成电路10电性连接。在本发明的较佳实施例中,每一触控单元311包括触控电极315,该触控电极315位于该触控单元311的外层,所述第一引线311通过过孔317与每一触控电极315电性连接。所述过孔317开设于所述触控单元311上,较佳地,该过孔317的排列方向与所述第一引线311的走线方向相同。可以理解,每一列的触控单元311也可以不是均匀、等间隔地排列在所述集成电路10的一侧。
在本发明的实施例中,每一列中的第一引线313均等间隔且并行排列,其中,每一条第一引线313只与其中一个对应的触控单元311电性连接,实现对每个触控单元311的信号的单独控制。具体地,本发明的实施例中,每一列的第一引线313包括从左到右依次等间距且平行排列的6条第一引线313,可依次定义为第一条第一引线313、第二条第一引线313、第三条第一引线313、第四条第一引线313、第五条第一引线313及第一条第一引线313。
具体为,第一条第一引线313通过所述过孔317电性连接至位于所述触控结构30最下端的触控单元311,且与相邻的靠近上端的下一个触控单元311之间断开后,再延伸至位于所述触控结构30最上端的触控单元311;第二条第一引线313从最下端的触控单元311延伸至下一个触控单元311,且通过所述过孔317电性连接至该触控单元311,与相邻的靠近上端的下一个触控单元311之间断开后,再延伸至最上端的触控单元311,依次类推,直至位于最右侧的第六条第一引线313从最下端的触控单元311延伸至位于所述触控结构30最上端的触控单元311,且通过所述过孔317电性连接至最上端的触控单元311。其中,第一引线313与相邻的靠近上端的下一个触控单元311断开的状态如图1中圆形虚线A所示,也即是说,通过所述过孔317与一触控单元311电性连接的第一引线311与相邻的且位于同一列并靠近所述触控结构30上端 的下一个触控单元311之间形成如图1中圆形虚线A所示的断开点。
本发明中的多个所述第一引线313从上端至下端排列贯穿整个触控区31,从而保证了所述触控结构30的电场分布的均匀性。同时,本发明所述的触控结构30中,所述第一引线313通过所述过孔317电性连接至相应的触控单元311后,便与相邻的下一个触控单元311之间断开,如此不但缩短了所述集成电路10端引出的每个触控单元311的走线,而且进而减小连接到每个触控单元311走线的负载,从而提高每个触控单元311灵敏度。
所述外围区33包括第二引线331,该第二引线331围绕该触控区31,每一列中的最后一条第一引线313(如图1中位于最右侧的第六条第一引线313),也就是与最上端的触控单元311电性相连的第一引线313,与所述第二引线331之间断开,剩余的第一引线313均与该第二引线331电性相连,其中,所述第一引线313与所述第二引线331的断开状态如图1中圆形虚线B所示。该第二引线331的末端与所述集成电路10相连,接收该集成电路10所发送的信号。
该触控结构30还包括第三引线35,该第三引线35位于相邻的两列触控单元311之间,用以防止相邻列之间的触控单元31之间产生信号干扰。该第三引线35的一端与该第二引线331电性相连,另一端延伸至该触控结构30的下端并靠近所述集成电路10,且与该集成电路10之间处于断开状态。
可以理解的是,图1所示的触控结构仅是本发明的其中一个实施例,其触控单元与对应的第一引线也并不局限于图1中所示,在其他实施例中,图1中圆形虚线A所示的断开点也可以为其他的分布方式,例如,第一条第一引线通过所述过孔并不局限于电性连接至位于所述触控结构最下端的触控单元,也可能电性连接至该触控结构中的其他任一触控单元,从而形成了不同于图1所示的圆形虚线A的分布方式。此外,本发明也并不局限于每一列中的最后一条第一引线313(如图1中位于最右侧的第六条第一引线313)与所述第二引线331之间断开,在其他实施例中,只要保证与最上端的触控单元电性相连的第一引线与所述第二引线之间处于断开状态即可。
综上所述,本发明实施例所述的具有触控结构30的液晶显示器100保证了整个触控结构30的电场的均匀分布,同时,在本发明所述的触控结构30中,所述第一引线313电性连接至相应的触控单元311,并与相邻的下一个触 控单元311之间断开,如此不但缩短了每个触控单元311的走线距离,而且减小了连接到每个触控单元311走线的负载,从而提高每个触控单元311灵敏度。
在本说明书的描述中,参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中,对上述术语的示意性表述不一定指的是相同的实施例或示例。而且,描述的具体特征、结构、材料或特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所揭露的仅为本发明一种较佳实施例而已,当然不能以此来限定本发明之权利范围,本领域普通技术人员可以理解实现上述实施例的全部或部分流程,并依本发明权利要求所作的等同变化,仍属于发明所涵盖的范围。
