Description

内嵌式触摸屏及显示装置 技术领域
本发明的实施例涉及一种内嵌式触摸屏及显示装置。 背景技术
内嵌式触摸屏 ( In Cell Touch Panel )是触摸屏和显示屏集成为一体的装 置。 触摸驱动电极和触摸感应电极被集成在显示屏中， 以同时实现触控和图 像显示的功能。 由于内嵌式触摸屏结构筒单、 轻、 薄， 成本低等特点， 已经 逐渐成为显示领域的主流。
参见图 1 , 图 1示出了横向设置的触摸驱动电极 800和纵向设置的触摸 感应电极 900。 相邻的触摸驱动电极 800和触摸感应电极 900之间耦合产生 交互电容 Cm ( mutual capacitance )。 当手指触碰屏幕时， 手指的触碰会改变 所述交互电容 Cm的值。触摸检测装置通过检测手指触碰前后电容 Cm对应的 电流的改变， 从而检测出手指触摸点的位置。
在内嵌式触摸屏中， 为了提高触摸屏的触控效果， 触摸驱动电极和触摸 感应电极的面积较大， 因而触控信号对图像显示信号会有干扰， 同时， 图像 显示信号也会对触控信号有干扰。 此外， 面积较大的触摸驱动电极和触摸感 应电极会降低触摸屏的开口率。 发明内容
本发明实施例提供一种内嵌式触摸屏及显示装置， 用以解决触控信号和 图像显示信号之间相互干扰的问题， 同时提高内嵌式触摸屏的开口率。

较佳地，所述触摸驱动电极包括多个相互平行且沿行方向分布的触摸驱 动电极子单元， 各触摸驱动电极子单元之间相互并联连接。

较佳地，该触摸屏还包括位于所述阵列基板上沿所述亚像素单元的行方 向分布的多条公共电极信号线，所述公共电极信号线包括第一公共电极信号 线和第二公共电极信号线。
所述第一公共电极信号线位于所述相邻的触摸驱动电极之间，且位于任 意相邻的两个亚像素单元组之间的非显示区域。所述第二公共电极信号线为 分时间驱动的所述多条触摸驱动电极。
较佳地， 所述第一公共电极信号线和第二公共电极信号线间隔排列。 较佳地，该触摸屏还包括位于所述阵列基板上且位于所述公共电极信号 线上方与所述公共电极信号线电性相连的公共电极， 该公共电极与所述触摸 驱动电极在垂直方向无交叠面。
较佳地，该触摸屏还包括所述阵列基板上且位于所述公共电极信号线上 方与所述公共电极信号线电性相连的公共电极， 该公共电极在与所述触摸驱 动电极相对应的区域设置有多个狭缝， 该公共电极与所述触摸驱动电极在垂 直方向的交叠面为所述狭缝的面积。
较佳地， 所述触摸感应电极为网格状， 该网格状触摸感应电极包括沿行 方向分布的第一触摸感应子电极和沿列方向分布的第二触摸感应子电极，所 述第一触摸感应子电极和第二触摸感应子电极之间电性相连。

本发明实施例提供一种显示装置， 包括上述内嵌式触摸屏。
本发明实施例提供的内嵌式触摸屏中， 由于栅线和触摸驱动电极位于阵 列基板上的不同区域， 即栅线和触摸驱动电极无垂直交叠面， 因此触摸驱动 电极的触摸驱动信号不会影响栅线的栅极扫描信号，从而避免了触摸驱动信 号对图像信号的影响。 并且， 触摸驱动电极设置在非显示区域， 即设置在与 彩膜基板上的黑矩阵相对应的区域， 从而不会影响触摸屏的开口率。 附图说明 为了更清楚地说明本发明实施例的技术方案，下面将对实施例的附图 作筒单地介绍， 显而易见地， 下面描述中的附图仅仅涉及本发明的一些实施 例， 而非对本发明的限制。 图 1为现有触摸驱动电极和触摸感应电极形成互电容的原理图； 图 2为本发明的一个实施例提供的阵列基板亚像素单元设置方式的示意 图；

除非另作定义， 此处使用的技术术语或者科学术语应当为本发明所属领 域内具有一般技能的人士所理解的通常意义。本发明专利申请说明书以及权 利要求书中使用的 "第一"、 "第二" 以及类似的词语并不表示任何顺序、 数 量或者重要性， 而只是用来区分不同的组成部分。 同样， "一个" 或者 "一" 等类似词语也不表示数量限制， 而是表示存在至少一个。 "包括" 或者 "包 含" 等类似的词语意指出现在 "包括" 或者 "包含" 前面的元件或者物件涵 盖出现在 "包括" 或者 "包含" 后面列举的元件或者物件及其等同， 并不排 除其他元件或者物件。 "连接" 或者 "相连" 等类似的词语并非限定于物理 的或者机械的连接， 而是可以包括电性的连接， 不管是直接的还是间接的。 "上"、 "下"、 "左"、 "右" 等仅用于表示相对位置关系， 当被描述对象的绝 对位置改变后， 则该相对位置关系也可能相应地改变。 本发明的实施例提供了一种内嵌式触摸屏及显示装置，用以解决触控信 号和图像显示信号之间相互干扰的问题， 同时提高内嵌式触摸屏的开口率。
本发明的一个实施例提供了内嵌式触摸屏， 其中， 每两行相邻的亚像素 单元为一个亚像素单元组。 所述两行相邻的亚像素单元之间设置有两条栅 线， 所述两条栅线分别为该两行亚像素单元提供栅极信号。 触摸驱动电极位 于相邻的亚像素单元组之间。栅线和触摸驱动电极位于阵列基板上的不同区 域且无垂直交叠面， 因此触摸驱动电极的触摸驱动信号不会影响栅线的栅极 扫描信号， 从而避免了触摸驱动信号对图像信号的影响。 并且， 触摸驱动电 极设置在非显示区域， 即设置在与彩膜基板上的黑矩阵相对应的区域， 因而 不会影响像素的开口率。
本发明一个实施例提供的内嵌式触摸屏可以是具有触摸功能的液晶显 示屏， 或者是具有触摸功能的有机发光显示屏等。
下面以液晶显示屏为例通过附图具体说明本发明实施例提供的技术方 案。
首先说明本发明的实施例提供的薄膜晶体管 TFT阵列基板的设置方式。 参见图 2, 所述薄膜晶体管 TFT阵列基板包括： 第一基板 1; 位于第一 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为一 个亚像素单元组 2;亚像素单元组 2中的两行相邻的亚像素单元 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 2所示的位于不同亚像素单元组 2中的栅线可分别标识为 Gl、 G2、
G3 G9和 G10。
本发明实施例提供的内嵌式触摸屏的触摸驱动电极设置在图 2所示的阵 列基板上， 例如， 设置在亚像素单元组 2之间的非显示区域。 触摸驱动电极的设置方式至少包括两种：
方式一： 如图 3所示， 触摸驱动电极 4包括一条触摸驱动子电极 41。 触 摸驱动子电极 41 ( 4 )设置在相邻的两行亚像素单元组 2之间的非显示区域。
触摸驱动电极 4可以设置在任意相邻的两个亚像素单元组 2之间， 或者 设置在部分相邻的两个亚像素单元组 2之间。 在具体实施过程中， 需要根据 实际触控精度需求来设置触摸驱动电极在阵列基板上的设置密度。
方式二： 如图 4所示， 触摸驱动电极 4包括至少两条（即多条）触摸驱 动子电极 41。 每一条触摸驱动子电极 41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 41之间相互并联连接， 例如， 可以通过阵列基 板周边的引线 42并联连接。
较佳地， 本发明实施例提供的所述触摸驱动电极与所述栅线同层设置。 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的纵向宽度较宽， 约在毫米量级。
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。 触摸驱动电极的纵向宽度为两条触摸驱动子电极之间的最长距 离。 如图 4所示的触摸驱动电极的纵向宽度为 a。
图 5是在图 3所示的阵列基板上设置有公共电极信号线的结构示意图。 阵列基板还包括： 沿亚像素单元 20的行方向分布的多条公共电极信号 线。公共电极信号线包括第一公共电极信号线 51和第二公共电极信号线 52。
第一公共电极信号线 51为位于相邻的触摸驱动电极 4 ( 41 )之间， 且位 于任意相邻的两个亚像素单元组 2之间的非显示区域的电极线， 第二公共电 极信号线 52为分时间驱动的多条触摸驱动电极 4 ( 41 ) ( 52 )。 即多条触摸驱 动电极 4 ( 41 ) ( 52 )分时间驱动。 在图像显示阶段， 驱动其为公共电极提供 电压信号实现图像显示； 在触控阶段， 驱动其实现触摸功能。
图 5所示的触摸驱动电极仅由一条触摸驱动子电极组成。
较佳地， 如图 5所示， 第一公共电极信号线 51和第二公共电极信号线 52间隔排列。
所述公共电极信号线用于为公共电极提供电压信号（即 V∞m电压信号）。 本发明实施例提供的公共电极信号线位于阵列基板的图像显示区域（即 A-A 区域）， 且位于 A-A区域中亚像素单元之间的非显示区域， 该公共电极信号 线为位于其上方的公共电极提供 Vcom电压， 公共电极的 V∞m电压更稳定。
具体实施过程中，在阵列基板的任意相邻的亚像素单元组之间设置与栅 线位于同一层的条状电极。所有的条状电极在图像显示阶段用作公共电极信 号线， 部分所述条状电极在触控阶段用作触摸驱动电极， 这既提高了像素的 开口率， 还能够为公共电极提供更稳定的 V∞m电压。
参见图 6, 本发明实施例提供的触摸屏还包括位于彩膜基板上的公共电 极 6。 该公共电极 6位于栅线 21、 第一公共电极信号线 51和第二公共电极 信号线 52的上方，并且与栅线 21、第一公共电极信号线 51和第二公共电极 信号线 52相绝缘。公共电极 6与第一公共电极信号线 51和第二公共电极信 号线 52通过过孔电性相连。第一公共电极信号线 51和第二公共电极信号线 52通过阵列基板上的***区域的引线与相应的芯片 IC或者驱动电路相连。 第一公共电极信号线 51和第二公共电极信号线 52为公共电极 6提供稳定的 V∞m电压信号。
较佳地， 如图 6所示， 公共电极 6与触摸驱动电极 4在垂直方向无交叠 面。 这样可以保证触摸驱动电极 4和触摸感应电极之间进行信号交换， 以实 现灵敏度较高的触摸功能。
图 6所示的各公共电极 6之间相互独立，相邻公共电极 6之间的缝隙与 触摸驱动电极 4相对应。
图 6所示的各公共电极 6之间相互独立。 然而， 各公共电极 6的电阻值 因面积不同而不同， 并且各公共电极 6接收到的 V∞m信号不均一，这样不利 于高质量的图像显示。
较佳地， 参见图 7, 公共电极 6与触摸驱动电极 4在垂直方向的交叠面 小于触摸驱动电极 4的面积。 公共电极 6为一整层导电膜层， 该导电膜层在 与触摸驱动电极 4相对应的区域设置有多个狭缝 61。 该狭缝 61使得触摸驱 动电极 4的一部分露出， 露出部分的触摸驱动电极 4与触摸感应电极进行信 号交换， 以实现触摸功能。 在具体实施过程中， 通过对与触摸驱动电极 4相 对应的区域的公共电极 6进行挖洞来实现狭缝 61。
图 8为图 7所示的公共电极 6的示意图，公共电极 6覆盖整个阵列基板 的显示区域（ A-A区域）， 公共电极 6上设置有狭缝 61。
为了提高触摸屏光线的透过率，公共电极 6在与亚像素单元对应的区域 设置为狭缝状，参见图 9。 图 9给出了在与每一亚像素单元 20对应的区域设 置有狭缝的公共电极 6的局部放大示意图。
下面具体介绍本发明实施例提供的触摸感应电极。
本发明实施例提供的触摸感应电极设置在彩膜基板上。参见图 10,触摸 感应电极 7为网格 ^犬。
网格状触摸感应电极 7包括沿行方向分布的第一触摸感应子电极 71和 沿列方向分布的第二触摸感应子电极 72。 第一触摸感应子电极 71和第二触 摸感应子电极 72之间电性相连。
阵列基板上还包括与栅线同层设置的数据线，数据线位于相邻的两列亚 像素单元之间。
较佳地，参见图 11 , 第一触摸感应子电极 71位于与栅线 21相对应的区 域， 第二触摸感应子电极 72位于与数据线相对应的区域。 图 11中未体现数 据线。
由图 11 可以清楚地看出， 本发明实施例提供的触摸感应电极位于与栅 线和数据线相对应的区域， 并没有占用像素显示区域， 从而提高了触摸屏的 开口率。
本发明实施例提供的触摸驱动电极与栅线和数据线同层设置， 并且可以 由同一次制作工艺形成。 触摸驱动电极可以是金属或者合金材料制成的电 极。
本发明实施例提供的公共电极为透明导电电极，例如铟锡氧化物 ITO或 铟辞氧化物 IZO等。
下面筒单说明本发明实施例提供的触摸驱动电极和触摸感应电极实现 触摸的原理。
图 12示出了相邻的触摸驱动电极 4和触摸感应电极 7之间形成的互电 容 Cm。 具体地， 每一个触摸驱动电极 4与触摸感应电极 7的沿行方向排列 的第一触摸感应子电极之间形成互电容 Cm, 以及与触摸感应电极 7沿列方 向排列的第二触摸感应子电极之间形成互电容 Cm。 可以通过调整触摸驱动 电极 7的密度来调整 (^的大小， 从而设计满足需求的触摸感应电极。
本发明实施例提供的触摸感应电极完全设置在与栅线和数据线相对应 的区域， 即触摸感应电极完全位于栅线和数据线的正上方。 为了避免触摸感 应电极接收到的信号会受到来自液晶显示面板的显示图像信号的干扰， 并且 为了避免触摸驱动电极与公共电极信号线共用的情况下的信号的干扰，触摸 驱动电极与公共电极信号线分时间驱动。
下面结合图 13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 13中， V-sync为时序信号。 图中示出了 n条栅线的时序， 其中 n条 栅线分别为栅线 1 ( Gl )、 栅线 2 ( G2 ) 栅线 m ( Gm )、 栅线 m+1 ( Gm+1 )、 栅线 m+2 ( Gm+2 )、 栅线 m+3 ( Gm+3 )、 栅线 n-1 ( Gn-1 )、 栅 线 n ( Gn )。 图中还是除了数据线的时序， n条触摸驱动电极 的时序 (Tl、 Τ
2, , Τη), 以及 η条触摸感应电极的时序 （Rl、 R2, , Rn )。
如图 13所示， 在前 11.7ms的图像显示阶段中， 为 n条栅线依次施加栅 极扫描信号电压， 同时为数据线施加数据信号电压。 为公共电极信号线施加 一定的恒定电压， 实现图像显示。 触摸感应电极不施加任何电压， 以避免对 图像显示的影响。 当一帧图像显示完后， 在下一帧图像显示之前的 5ms 的触摸显示阶段 内， 为栅线、 数据线施加低电平信号， 使得与栅线相连的 TFT关断， 从而避 免对触控过程的影响； 为触摸驱动电极施加一个触摸驱动电压 V1 以及同时 为触摸感应电极施加恒定电压 V。。 施加有电压 V。的触摸感应电极和施加有 电压 的触摸驱动电极之间形成电场， 由此实现触摸功能。
上述图像显示阶段的 11.7ms以及触摸显示阶段的 5ms只是为了说明本 发明所示的一个示例，在具体实现过程中，图像显示阶段的不限于为 11.7ms, 触摸显示阶段不限于为 5ms。
本发明的一个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、 有机电致发光显示 OLED 面板、 OLED显示器、 OLED电视或电子纸等显示装置。
综上所述， 本发明实施例提供了一种内嵌式触摸屏， 其中， 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； 触摸驱动电极位于相邻的亚像素 单元组之间。 由于栅线和触摸驱动电极位于阵列基板上的不同区域， 即栅线 和触摸驱动电极无垂直交叠面， 因而触摸驱动电极的触摸驱动信号不会影响 栅线的栅极扫描信号， 从而避免了触摸驱动信号对图像信号的影响。 并且， 触摸驱动电极设置在非显示区域， 即设置在与彩膜基板上的黑矩阵相对应的 区域， 因而不会影响像素的开口率。
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。
