Description

一种阵列基板、内嵌式触摸屏及显示装置
技术领域
本发明涉及显示技术领域，尤其涉及一种阵列基板、内嵌式触摸屏及显示装置。
背景技术
触摸屏（TouchPanel，TP）包括外挂式触摸屏（AddOnTouchPanel）和内嵌式触摸屏（InCellTouchPanel）。
InCellTouchPanel为触摸驱动电极和触摸感应电极集成在液晶显示屏内的触摸屏，该触摸屏由于其结构简单、显示性能高且成本低等优点已经逐渐成为触摸显示领域的主流。
目前，液晶显示屏按照显示模式至少可以分为：扭曲向列（TwistedNematic，TN）型、平面转换（InPlaneSwitching，IPS）型和高级超维场开关（AdvancedSuperDimensionSwitch，ADS）型等。其中，ADS显示模式的液晶显示屏是通过同一平面内电极边缘所产生的电场以及电极层与板状电极层间产生的电场形成多维电场，使在电极之间和电极正上方的所有液晶分子发生旋转，实现图像显示。相对于IPS显示模式的液晶显示屏，能够提高液晶的工作效率且能够增加透光效率。ADS显示模式的液晶显示屏具有高画面品质、高分辨率、高透过率、低功耗、宽视角、高开口率、低色差、无水波纹（pushMura）等优点。
液晶显示屏主要包括彩膜基板、阵列基板以及位于彩膜基板和阵列基板之间的液晶层。现有触摸屏通过将触摸感应电极设置在彩膜基板上，触摸驱动电极设置在阵列基板上实现内嵌式触摸和图像显示的功能。
现有内嵌式触摸屏由于触摸驱动电极和触摸感应电极分别设置在阵列基板和彩膜基板上，触摸屏的结构较复杂且厚度较厚。另外，彩膜基板上的触摸感应电极和阵列基板上的触摸驱动电极由于相距较远分别与两颗IC相连，实现内嵌式触摸的功能，在具体实施过程中，两颗IC的匹配难度较大。
发明内容
本发明实施例提供了一种阵列基板、内嵌式触摸屏及显示装置，用以实现一种结构简单的内嵌式触摸屏。
本发明实施例提供的阵列基板，包括：呈矩阵排列的多个亚像素单元，每两行相邻的亚像素单元为一个亚像素单元组，该两行亚像素单元之间设置有两条分别为该两行亚像素单元提供栅极信号的栅线；
位于所述阵列基板上的亚像素单元组之间的多条沿所述亚像素单元的行方向分布的触摸驱动电极；以及
位于所述阵列基板上的多条沿所述亚像素单元的列方向分布且与所述触摸驱动电极和所述栅线相绝缘的触摸感应电极。
较佳地，所述触摸感应电极位于所述触摸驱动电极上方，所述触摸感应电极在触控阶段为构成公共电极的公共子电极。
较佳地，所述各触摸感应电极在与所述触摸驱动电极交叠的区域设置有多个设定大小的开口。
较佳地，还包括，位于每一触摸感应电极下方亚像素单元组中的两条栅线之间的金属线，该金属线与所述触摸感应电极通过过孔连接。
较佳地，还包括，位于两个相邻的亚像素单元组之间沿亚像素单元的行方向排列且与所述各公共子电极通过过孔相连的公共电极信号线。
较佳地，所述栅线、金属线、公共电极信号线和触摸驱动电极线同层设置。
较佳地，所述触摸驱动电极与所述公共电极信号线间隔设置。
较佳地，所述触摸驱动电极包括多条沿行方向分布的触摸驱动子电极，触摸驱动子电极位于相邻的两个亚像素单元组之间，各触摸驱动子电极之间相互并联连接。

本发明实施例提供一种显示装置，包括所述内嵌式触摸屏。
本发明提供的内嵌式触摸屏的阵列基板上集成有实现触摸功能的触摸驱动电极和触摸感应电极，一方面可以降低内嵌式触摸屏的整体厚度，另一方面也最大限度的降低了IC匹配难度，提高了产品的竞争力。

具体实施方式
本发明实施例提供了一种阵列基板、内嵌式触摸屏及显示装置，用以实现一种结构简单的内嵌式触摸屏。
本发明实施例提供的内嵌式触摸屏为触摸驱动电极和触摸感应电极集成在高级超维场开关（AdvancedSuperDimensionSwitch，ADS）显示模式的显示屏中的触摸屏。本发明实施例提供的内嵌式触摸屏包括对盒而置的彩膜基板和阵列基板以及位于彩膜基板和阵列基板之间的液晶层；触摸驱动电极和触摸感应电极位于所述阵列基板上。本发明实施例提供的阵列基板为基于双栅线（WXGADualGate）结构的阵列基板。
以下将结合附图具体说明本发明提供的内嵌式触摸屏，主要说明具有触摸功能的阵列基板。
参见图1，为本发明提供的阵列基板的俯视示意图，包括：
基板1；位于基板1上呈矩阵分布的多个亚像素单元20，两行相邻的亚像素单元20构成一个亚像素单元组2；亚像素单元组2中的两行亚像素单元20之间设置有两条栅线21，两条栅线21分别为两行亚像素单元20提供栅极扫描信号。图1所示的栅线21从上至下分别为G1、G2、G3、.....、G9和G10。还包括：位于亚像素单元组2之间的多条沿亚像素单元20的行方向分布的触摸驱动电极3；以及多条沿亚像素单元20的列方向分布且与触摸驱动电极3和栅线21相绝缘的触摸感应电极4。
为了更清楚地说明本发明图1所示的触摸驱动电极3和触摸感应电极4之间的相对位置。参见图2，为图1所示的阵列基板在A-A’向的截面示意图；亚像素单元20、栅线21和触摸驱动电极3位于基板1上，绝缘层5位于亚像素单元20、栅线21和触摸驱动电极3上，触摸感应电极4位于绝缘层5上；图2中仅示出两条触摸驱动电极3和一条触摸感应电极4。
需要说明的是，本发明触摸驱动电极3和触摸感应电极4的位置不限于图2所示设置方式，二者的位置也可以互换。较佳地，图2所示的触摸感应电极4设置在触摸驱动电极3上方，触摸感应电极4距离人手指的距离较近，触控效果较好。
上述本发明提供的阵列基板集成有实现触摸功能的触摸驱动电极和触摸感应电极，该设置方式一方面可以降低内嵌式触摸屏的整体厚度，另一方面便于将触摸驱动电极的驱动IC和触摸感应电极的感应IC集成在同一颗IC上，最大限度的降低了IC匹配难度，简化了内嵌式触摸屏的结构，提高了产品的竞争力。
本发明提供的触摸驱动电极的设置方式至少包括以下两种：
方式一：如图1或图2所示，触摸驱动电极3包括一条触摸驱动子电极31。触摸驱动子电极31（3）设置在相邻的两行亚像素单元组2之间的非显示区域。
方式二：如图3所示，触摸驱动电极包括至少两条（即多条）触摸驱动子电极31。每一条触摸驱动子电极31设置在相邻的两个亚像素单元组2之间。多条触摸驱动子电极31之间相互并联连接，具体可以通过阵列基板周边的引线32并联连接。
所述方式一提供的触摸驱动电极的纵向（即列方向）宽度较窄，约在微米量级。方式二提供的触摸驱动电极所覆盖的纵向宽度较宽，约在毫米量级。所述触摸驱动电极的纵向宽度为第一条触摸驱动子电极和第二条触摸驱动子电极之间的最长距离。如图3所示的触摸驱动电极的纵向宽度为a。
较佳地，方式二提供的触摸驱动电极的纵向宽度可以设置在2mm～6mm的范围内，触摸驱动电极由多条触摸驱动子电极并联连接而成。
本发明提供的触摸驱动电极3可以与栅线21位于同一层或也可以位于不同层。为了减少制作触摸屏的工艺流程，较佳地，触摸驱动电极3与栅线21位于同一层。在具体实施过程中，触摸驱动电极3和栅线21在同一次制作工艺中完成，只需要一次掩膜（MASK）工艺，大大降低触摸屏的制作成本。
本发明提供的阵列基板，可以在任意相邻的两个亚像素单元组2之间设置触摸驱动电极3（或触摸驱动子电极31），也可以在部分相邻的两个亚像素单元组2之间设置触摸驱动电极3（或触摸驱动子电极31）。具体可以根据实际触控精度的需求而定，一般地，触摸驱动电极3（或触摸驱动子电极31）设置在部分相邻的两个亚像素单元组2之间较佳。图1或图2所示的阵列基板中，每间隔两组亚像素单元组3设置一条触摸驱动电极3（或触摸驱动子电极31）。
本发明提及的两个亚像素单元组2之间均为非显示区域（即与彩膜基板上的黑矩阵BM对应的区域），本发明触摸驱动电极3设置在与黑矩阵BM对应的区域，不影响像素的开口率和光透过率。
参见图4，为图1所示的阵列基板设置有多条公共电极信号线7的结构示意图；具体地，公共电极信号线7沿亚像素单元20的行方向分布，公共电极信号线7位于相邻的触摸驱动电极3之间，且位于任意相邻的两个亚像素单元组2之间。该公共电极信号线7与位于像素电极上方的各公共子电极（即公共电极）通过过孔连接，为公共电极提供信号均一且稳定的电压信号（即Vcom电压信号）。
图4所示的触摸驱动电极3仅由一条触摸驱动子电极组成。较佳地，公共电极信号线7与触摸驱动电极3间隔排列。
较佳地，图4所示的触摸驱动电极3、公共电极信号线7和栅线21同层设置，在具体实施过程中，三者在同一次制作工艺中完成，只需要一次掩膜（MASK）工艺，大大降低触摸屏的制作成本。
需要说明的是，本发明触摸驱动电极在图像显示阶段也可用作公共电极信号线，公共电极信号线在触控阶段也可以用作触摸驱动电极，在图像显示阶段施加Vcom电压信号，在触控阶段施加高频信号。
参加图5，本发明提供的阵列基板还包括：用于在图像显示阶段实现图像显示的公共电极6；其中，公共电极6包括多条公共子电极61，各公共子电极61与各触摸感应电极4为同一电极。换句话说，各触摸感应电极4在图像显示阶段作为公共子电极，各公共子电极构成公共电极。
当本发明提供的公共电极6位于触摸驱动电极3上方时，为了提高液晶层的液晶分子的工作效率且能够增加透光效率，较佳地，公共电极6中的各公共子电极61为狭缝状电极。也就是说，本发明提供的触摸感应电极4为在与每一亚像素单元相对应的区域设置有狭缝的狭缝状电极。为了更清楚地说明狭缝状触摸感应电极4，参见图6为一条触摸感应电极4的放大结构示意图。图6中虚线框所围成的区域对应一各亚像素单元20所在区域。
需要说明的是，本发明当公共电极为狭缝状电极时，像素电极为板状电极，这样的设置方式可以实现高品质的图像显示。
较佳地，为保证触摸驱动电极和触摸感应电极之间的投射电场穿出到触摸屏面板的表面被人手指感应，以提高触控效果，参见图7，本发明实施例提供的各触摸感应电4在与触摸驱动电极3对应的区域设置有多个具有一定大小的开口41，即各触摸感应电极4在与触摸驱动电极3交叠的区域设置有多个设定大小的开口，使得电场线可以穿出，电场线被人的手指触碰到。
为了更清楚地说明所述投射电场，图8为图7所示的区域B的局部放大立体示意图。带箭头的虚线10表示投射电场的电场线，电场线10由触摸驱动电极3（31）经触摸感应电极4（61）的开口41被人手指11接触，提高触摸的灵敏度，触控效果更佳。
参见图9，本发明提供的阵列基板还包括：
位于每一亚像素单元组2中的两条栅线21之间与每一触摸感应电极4相连的金属线9，该金属线9沿与栅线21平行的方向排列，且长度不超过触摸感应电极4的宽度，该金属线9用于降低与之相连的公共子电极61的电阻。这是因为，金属线的电阻率相比较金属氧化物的电阻率小得多，当同时用作公共电极的各触摸感应电极4由透明金属氧化物制作而成时，各触摸感应电极4的电阻值较大，不利于实现较佳的触控效果，在各触摸感应电极4上并联连接金属线9时，各触摸感应电极4的电阻值会大大降低，触控效果会明显提高。
较佳地，金属线9与触摸驱动电极3、公共电极信号线7和栅线21同层设置。在具体实施过程中，金属线9、触摸驱动电极3、公共电极信号线7和栅线21在同一次制作工艺中完成，只需要一次掩膜（MASK）工艺，大大降低触摸屏的制作成本。
本发明实施例提供的内嵌式触摸屏包括上述任一种方式的阵列基板，该阵列基板同时集成触摸驱动电极和触摸感应电极，触摸驱动电极的驱动IC和触摸感应电极的感应IC可以集成在同一颗IC上，整个内嵌式触摸屏的结构简单。且现有的公共电极用作触摸感应电极，触摸驱动电极与栅线同层设置，结构上没有额外增加功能膜层，进一步简化内嵌式触摸屏的结构，提高产品的竞争力。
以下结合图10所示的实现图像显示和触摸功能的时序图，具体说明本发明实施例提供的内嵌式触摸屏的工作原理。
图10中，V-sync为时序信号。包括n条栅线的时序、数据线Date的时序、触摸驱动电极Tx的时序、触摸感应电极Rx的时序和公共电极信号线Com的时序。n条栅线分别为栅线1（Gate1）、栅线2（Gate2）、、、、、、栅线n-1（Gaten-1）、栅线n（Gaten）。
如图10所示，内嵌式触摸屏显示一帧图像的时间为16.67ms，选取4ms作为触控阶段，其余12.67ms为图像显示阶段。
在触控阶段，数据线Data和n条栅线处于低电平非工作状态，不影响触摸过程。触摸驱动电极Tx和触摸感应电极Rx处于工作状态，实现触摸功能。
在图像显示阶段，触摸驱动电极Tx和触摸感应电极Rx处于低电平非工作状态（对应与相应的电压源保持断路），避免对图像显示的影响。n条栅线和数据线Data处于高电平工作状态，实现图像显示。
公共电极信号线Com一直保持恒压状态DC-Vcom，在触控阶段不影响触控效果，在图像显示阶段为公共电极传输Vcom信号。
上述图像显示阶段的12.67ms以及触摸显示阶段的4ms只是为了说明本发明所示的一个个例，在具体实现过程中，图像显示阶段的不限于为12.67ms，触摸显示阶段不限于为4ms。
本发明实施例还提供一种显示装置，包括上述内嵌式触摸屏，该显示装置可以为液晶显示器、液晶电视等。
综上所述，本发明提供的内嵌式触摸屏的阵列基板上集成有实现触摸功能的触摸驱动电极和触摸感应电极，一方面可以降低内嵌式触摸屏的整体厚度，另一方面便于将触摸驱动电极的驱动IC和触摸感应电极的感应IC集成在同一颗IC上，最大限度的降低了IC匹配难度，简化了内嵌式触摸屏的结构，提高了产品的竞争力。另外，所述触摸感应电极与阵列基板中用于实现图像显示的公共电极共用，公共电极分为多个条状的公共子电极，公共子电极分时间驱动，实现触控和显示功能，在结构上并不增加任何功能膜层，更进一步简化了内嵌式触摸屏的结构，降低了产品的制作成本。触摸驱动电极与栅线同层设置，结构简单，制作工艺流程简单。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
