Description

阵列基板及触控显示装置
本申请要求享有2015年5月11日提交的名称为“阵列基板及触控显示装置”的中国专利申请CN201510236147.5的优先权，其全部内容通过引用并入本文中。
技术领域
本发明涉及显示技术领域，具体地说，涉及一种阵列基板及触控显示装置。
背景技术
随着显示技术的发展，液晶显示器已经成为最为常见的显示装置。
另一方面，随着智能电子产品的普及，电容式触控屏也被广泛的应用于手机、平板电脑等各种电子产品中。目前较为多见的电容式触控屏有OGS(One glass solution)、on-cell和in-cell三种技术。其中，in-cell技术由于其制作工艺上的优势，相比于OGS技术和on-cell技术，具有更加轻薄、透光性更好的优点。
但是，现有技术至少存在以下技术问题：目前，in-cell技术中都会对公共电极进行切割处理，从而对其分区，如图1和图2所示，in-cell触控显示装置中包括被切割形成的若干公共电极1及若干寻址线2，每个公共电极1各自通过一条寻址线2连接至驱动电路3。在显示图像时，公共电极1通过寻址线2连接至驱动电路3中的公共电压输出端；在触控扫描时，公共电极1通过寻址线2连接至驱动电路3中的触控信号处理器。但是，当数据线4进行信号传输时，其产生的电场会穿过公共电极1之间的缝隙10，而干扰该位置的液晶5的旋转方向，导致该位置存在漏光的技术问题。
发明内容
本发明的目的在于提供一种阵列基板及触控显示装置，以解决现有的触控显示装置存在漏光的技术问题。
本发明提供一种阵列基板，包括由若干栅线和若干数据线划分成的子像素单元阵列，还包括若干公共电极，相邻的所述公共电极之间存在缝隙；
在缝隙的对应位置设置有屏蔽线；
在显示图像时，所述屏蔽线与所述公共电极的电位相同。
优选的是，部分所述数据线位于所述屏蔽线正下方。
进一步的是，该阵列基板还包括若干寻址线，每个所述公共电极各自通过一条寻址线连接至驱动电路。
优选的是，所述屏蔽线可以与所述寻址线位于同一图层。
优选的是，所述寻址线为金属材料或透明导体材料。
进一步的是，每个所述子像素单元中设置有薄膜晶体管和像素电极。
优选的是，所述屏蔽线也可以与所述像素电极位于同一图层。
优选的是，所述像素电极位于所述公共电极上方。
本发明还提供一种触控显示装置，包括彩膜基板和上述的阵列基板。
进一步的是，在显示图像时，所述公共电极通过所述寻址线连接至驱动电路中的公共电压输出端；
在触控扫描时，所述公共电极通过所述寻址线连接至驱动电路中的触控信号处理器。
本发明带来了以下有益效果：本发明提供的技术方案中，在公共电极之间的缝隙处，对应设置有屏蔽线，而且屏蔽线的电位与公共电极相同。当数据线进行信号传输时，屏蔽线能够对数据线产生的电场进行屏蔽，使该电场不能通过缝隙影响到液晶的旋转，从而解决了现有的触控显示装置存在漏光的技术问题。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要的附图做简单的介绍：
图1是现有的触控显示装置的示意图；
图2是图1中沿A-A线的剖面图；
图3是本发明实施例一提供的触控显示装置的示意图；
图4是本发明实施例二提供的触控显示装置的示意图。
具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是， 只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
实施例一：
本发明实施例提供一种触控显示装置，可以是手机、平板电脑等采用in-cell技术的触控显示装置。如图3所示，该触控显示装置由阵列基板110、彩膜基板120、液晶130、驱动电路(图中未示出)等部分组成。
阵列基板110由下至上依次包括衬底基板100、第一金属层、第一绝缘层1041、第二金属层、第二绝缘层1042、第一透明电极层、第三绝缘层1043、第三金属层、第四绝缘层1044、第二透明电极层、取向层105等结构。具体包括由若干栅线(图中未示出)和若干数据线101划分成的子像素单元阵列，以及若干公共电极102。其中，栅线位于第一金属层，数据线101位于第二金属层，公共电极102位于第一透明电极层。
每个子像素单元中设置有薄膜晶体管(图中未示出)和像素电极103，且像素电极103位于公共电极102上方。本实施例中，阵列基板110还包括若干寻址线(图中未示出)，每个公共电极102各自通过一条寻址线连接至驱动电路。其中，像素电极103位于第二透明电极层，寻址线位于第三金属层。
在显示图像时，公共电极102通过寻址线连接至驱动电路中的公共电压输出端，使公共电极102与像素电极103之间形成电场，从而使液晶130发生旋转。在触控扫描时，公共电极102通过寻址线连接至驱动电路中的触控信号处理器，以接收触控信号。
本实施例中，相邻的公共电极102之间存在缝隙1020，在缝隙1020的对应位置设置有屏蔽线106。在显示图像时，屏蔽线106与公共电极102的电位相同，用于屏蔽数据线101在信号传输时产生的电场。因为公共电极102之间的缝隙1020通常都与数据线101的位置相对应，所以在缝隙1020的对应位置设置屏蔽线106，就可以使相应的数据线101位于屏蔽线106正下方，从而更好的起到屏蔽作用。
在触控扫描时，因为数据线101上不需传输信号，所以不会影响到液晶130的旋转。因此，在触控扫描时，屏蔽线106可以是接地电位，也可以与公共电极102的电位相同。
本发明实施例提供的触控显示装置中，在公共电极102之间的缝隙1020处，对应设置有屏蔽线106，而且屏蔽线106的电位与公共电极102相同。当数据线101进行信号传输时，屏蔽线106能够对数据线101产生的电场进行屏蔽，使该电场不能通过缝隙1020影响到液晶130的旋转，从而解决了现有的触控显示装置存在漏光的技术问题。
作为一个优选方案，本实施例中的屏蔽线106与寻址线位于同一图层，即二者都位于第三金属层。在阵列基板的制造过程中，屏蔽线106和寻址线可以在同一次构图工艺中形 成，而不需要为屏蔽线106单独进行一次构图工艺。
本实施例中，屏蔽线106和寻址线均由金属材料形成。在其他实施方式中，屏蔽线106或寻址线也可以采用透明导体材料形成，例如铟锡氧化物(Indium Tin Oxide，简称ITO)等。
实施例二：
本发明实施例提供一种触控显示装置，可以是手机、平板电脑等采用in-cell技术的触控显示装置。如图4所示，该触控显示装置由阵列基板210、彩膜基板220、液晶230、驱动电路(图中未示出)等部分组成。
阵列基板220由下至上依次包括衬底基板200、第一金属层、第一绝缘层2041、第二金属层、第二绝缘层2042、第一透明电极层、第三绝缘层2043、第三金属层、第四绝缘层2044、第二透明电极层、取向层205等结构。具体包括由若干栅线(图中未示出)和若干数据线201划分成的子像素单元阵列，以及若干公共电极202。其中，栅线位于第一金属层，数据线201位于第二金属层，公共电极202位于第一透明电极层。
每个子像素单元中设置有薄膜晶体管(图中未示出)和像素电极203，且像素电极203位于公共电极202上方。本实施例中，阵列基板220还包括若干寻址线(图中未示出)，每个公共电极202各自通过一条寻址线连接至驱动电路。其中，像素电极203位于第二透明电极层，寻址线位于第三金属层。
在显示图像时，公共电极202通过寻址线连接至驱动电路中的公共电压输出端，使公共电极202与像素电极203之间形成电场，从而使液晶230发生旋转。在触控扫描时，公共电极202通过寻址线连接至驱动电路中的触控信号处理器，以接收触控信号。
本实施例中，相邻的公共电极202之间存在缝隙2020，在缝隙2020的对应位置设置有屏蔽线206。在显示图像时，屏蔽线206与公共电极202的电位相同，用于屏蔽数据线201在信号传输时产生的电场。因为公共电极202之间的缝隙2020通常都与数据线201的位置相对应，所以在缝隙2020的对应位置设置屏蔽线206，就可以使相应的数据线201位于屏蔽线206正下方，从而更好的起到屏蔽作用。
在触控扫描时，因为数据线201上不需传输信号，所以不会影响到液晶230的旋转。因此，在触控扫描时，屏蔽线206可以是接地电位，也可以与公共电极202的电位相同。
本发明实施例提供的触控显示装置中，在公共电极202之间的缝隙2020处，对应设置有屏蔽线206，而且屏蔽线206的电位与公共电极202相同。当数据线201进行信号传输时，屏蔽线206能够对数据线201产生的电场进行屏蔽，使该电场不能通过缝隙2020影响到液晶230的旋转，从而解决了现有的触控显示装置存在漏光的技术问题。
作为一个优选方案，本实施例中的屏蔽线206与像素电极203位于同一图层，即二者都位于第二透明电极层。在阵列基板的制造过程中，屏蔽线206和像素电极203可以在同一次构图工艺中形成，而不需要为屏蔽线206单独进行一次构图工艺。
虽然本发明所公开的实施方式如上，但所述的内容只是为了便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所公开的精神和范围的前提下，可以在实施的形式上及细节上作任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
