Description

内嵌式触摸屏及显示装置 技术领域
本发明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 ) 为触摸屏和显示屏集成为一体的触 摸显示屏， 即触摸驱动电极和触摸感应电极集成在显示屏中。 内嵌式触摸屏 可同时实现触控和图像显示的功能。 由于内嵌式触摸屏具有结构筒单、 轻、 薄， 成本低等的特点， 已经逐渐成为显示技术领域的主流。
在内嵌式触控技术中， 常见的触摸驱动电极和触摸感应电极为在阵列基 板与黑色矩阵对应的区域增加与栅极扫描线相平行的电极和与数据信号线 相平行的电极。 具体地， 参见图 1 , 为现有内嵌式触摸屏， 包括： 多条横向 分布的栅极扫描线 10、 多条纵向分布的数据信号线 20, 以及栅极扫描线 10 和数据信号线 20围设而成的子像素单元。如图 1中的红色子像素单元（R )、 绿色子像素单元（G )和蓝色子像素单元（B )。 多个子像素单元呈矩阵排列。 内嵌式触摸屏还包括位于相邻的两个子像素单元之间与栅极扫描线 10相平 行的触摸驱动电极 30, 以及位于相邻的两个子像素单元之间与数据信号线 20相平行的触摸感应电极 40。
由于触摸驱动电极 30和触摸感应电极 40与栅极扫描线 10和数据信号 线 20通过同一次工艺制作而成， 触摸驱动电极 30和触摸感应电极 40为不 透明的电极， 且位于相邻子像素单元之间的非显示区域。
图 1所示的内嵌式触摸屏，栅极扫描线和触摸驱动电极需要保持一定距 离以保证相互绝缘， 并且数据信号线与触摸感应电极需要保持一定距离以保 证相互绝缘。 因此， 各子像素单元的开口率较低。 发明内容

本发明实施例提供了一种内嵌式触摸屏及显示装置， 用以提高内嵌式触 摸屏的开口率。
首先筒单介绍下内嵌式触摸屏的工作原理。 指触碰触摸屏时， 手指改变了相邻电极之间的耦合电容。 因此， 可以通过检 测触摸点耦合电容的变化值确定触摸点位置。
本发明实施例提供的触摸屏中，触摸驱动电极和触摸感应电极设置在彩 膜基板或阵列基板上， 且为单面搭桥式设计（即触摸驱动电极和触摸感应电 极设置在同一层， 断开的电极通过搭桥的方式连接）。 当触摸驱动电极和触 摸感应电极设置在阵列基板上时， 它们与栅线或数据线位于不同层。 这样设 置的优点包括，触摸驱动电极和触摸感应电极不会影响阵列基板上像素的开 口率， 且触摸驱动电极和触摸感应电极设置在同一层减小了触摸屏的厚度。
本发明实施例提供了一种内嵌式触摸屏， 包括相对设置的第一基板和第 二基板，还包括位于所述第一基板上靠近第二基板的一侧或所述第二基板上 靠近第一基板的一侧的多条沿第一方向延伸的第一电极， 以及多条沿与所述 第一方向交叉的第二方向延伸的第二电极； 所述第一电极和第二电极同层设 置且相互绝缘。 其中， 所述第一电极包括多个相互独立的电极单元， 所述电 极单元与所述第二电极间隔排列，属于同一第一电极且位于所述第二电极两 侧的两个电极单元通过桥接线电性相连。
例如， 第一基板或第二基板为彩膜基板或阵列基板。 在本发明实施例中 是以第一基板为彩膜基板进行说明的。 以下通过附图具体说明本发明实施例提供的技术方案。
需要说明的是本发明实施例提供的触摸驱动电极和触摸感应电极可以 都设置在彩膜基板上， 或者也可以都设置在阵列基板上。
本发明的触摸驱动电极和触摸感应电极可以内嵌在液晶显示屏（ LCD ) 中， 也可以内嵌在有机电致发光显示屏（ OLED )中等。 图 3以 LCD为例说 明所述内嵌式触摸屏。
以下首先以触摸驱动电极和触摸感应电极设置在 LCD的彩膜基板上为 例说明。
参见图 2, 为本发明实施例提供的内嵌式触摸屏的俯视图。 如图所示的 内嵌式触摸屏， 包括： 相对设置的第一基板 1和第二基板， 位于第一基板 1 和第二基板之间的液晶层， 图 2中未体现第二基板和液晶层。
第一基板 1上设置有多个与子像素单元， 如红色子像素单元（R )、 绿色 子像素单元（G )和蓝色子像素单元（B ), 对应的彩色树脂层 12。 内嵌式触 摸屏还包括呈矩阵排列的黑矩阵 11 ,以及位于第一基板 1上的多条沿第一方 向（图 2中所示为横向）延伸的第一电极 14, 和多条沿与第一方向交叉的第 二方向 （图 1中所示为纵向）延伸的第二电极 15 , 第一电极 14和第二电极 15同层设置且相绝缘， 第一电极 14包括多个相互独立的电极单元 141 , 位 于第二电极 15两侧的两个电极单元 141通过桥接线 142连接。
例如， 在具体实施过程中， 第一电极为触摸驱动电极， 第二电极为触摸 感应电极； 或者第一电极为触摸感应电极， 第二电极为触摸驱动电极。
所述第一方向和第二方向相互垂直， 所述第一方向可以为横向， 所述第 二方向可以为纵向； 或者所述第一方向可以为纵向， 所述第二方向可以为横 向。
以下以第一电极为触摸驱动电极， 第二电极为触摸感应电极为例具体说 明本发明实施例提供的内嵌式触摸屏。
参见图 3 , 为图 2所示的内嵌式触摸屏在 A-A，向的截面图。 如图所示， 内嵌式触摸屏包括： 相对设置的第一基板 1和第二基板 2, 位于第一基板 1 和第二基板 2之间的液晶层 3 , 位于第一基板 1上靠近液晶层 3的一侧的黑 矩阵 11和彩色树脂 12 (如图 3中的 R、 G、 B树脂层）， 以及位于黑矩阵 11 和彩色树脂 12上的平坦层 13。
其中， 所述黑矩阵与所述彩色树脂可以同层设置， 也可以不同层设置。 例如， 第一电极和第二电极可以位于第一基板上的任意具有绝缘作用的 两层膜层之间。 例如， 第一电极和第二电极位于第一基板与黑矩阵层之间； 或者位于黑矩阵层和所述彩色树脂层之间； 或者位于所述彩色树脂层和平坦 层之间； 或者位于所述平坦层之上。
如图 3所示的内嵌式触摸屏，其中，黑矩阵 11和彩色树脂 12同层设置， 触摸驱动电极 14和触摸感应电极 15同层绝缘设置且位于平坦层 13之上。 触摸驱动电极 14包括多个相互独立的触摸驱动电极单元 141 ,触摸驱动电极 单元 141与触摸感应电极 15间隔排列。触摸感应电极 15两侧属于同一触摸 驱动电极 14的两个触摸驱动电极单元 141之间通过桥接线电性相连（图 3 中未体现桥接线）。
需要说明的是， 在本实施例中 （图 2和图 3所示的内嵌式触摸屏）， 第 一基板上设置有平坦层。 但在具体实施过程中， 内嵌式触摸屏上也可以不设 置平坦层。 参见图 4, 为图 2所示的内嵌式触摸屏在 B-B，向的截面图。 如图 所示， 内嵌式触摸屏包括： 第一基板 1 , 位于第一基板 1上的黑矩阵 11 , 位 于黑矩阵 11上的桥接线 142; 位于桥接线 142上的平坦层 13 , 位于平坦层 13上的触摸驱动电极 14和触摸感应电极 15。
其中， 平坦层 13上与桥接线 142和各触摸驱动电极单元 141对应的区 域设置有过孔， 触摸驱动电极 14中的各触摸驱动电极单元 141通过所述过 孔电性相连。
图 5为本发明实施例提供的触摸驱动电极 14和触摸感应电极 15 , 以及 二者与桥接线 142之间的连接关系示意图。 每一条触摸驱动电极 14的触摸驱动电极单元 141通过桥接线 142电性 相连。 触摸驱动电极单元 141与桥接线 142位于不同层， 通过图 5所示的过 孔 143连接。 桥接线 142与触摸感应电极 15相绝缘。
需要说明的是， 本发明实施例提供的桥接线与所述触摸驱动电极和触摸 感应电极位于不同层。 可以理解的是， 它们可以位于相邻的具有绝缘作用的 两层膜层之间。 桥接线还可以与黑矩阵同层设置。
图 5所示的桥接线 142可以位于如图 4所示的黑矩阵 11与平坦层 13之 间， 该黑矩阵 11为不导电的绝缘层， 桥接线 142还可以设置在触摸驱动电 极 14和触摸感应电极 15上方， 且与触摸感应电极 15相绝缘。 对应的触摸 屏的设置方式如图 6所示。 图 6所示的触摸屏的与图 3或图 4所示的触摸屏 的结构类似， 不同之处在于， 桥接线 142位于触摸驱动电极 14和触摸感应 电极 15上方， 与触摸感应电极 15通过绝缘层 16相互绝缘。
较佳地， 图 4或图 6所示的触摸屏， 其中， 桥接线 142的宽度不大于黑 矩阵 11的宽度。
较佳地， 图 4或图 6所示的触摸屏， 其中， 桥接线 142位于与黑矩阵 11 相对应的区域。 即桥接线 142在第二基板 2上的投影位于黑矩阵 11在第二 基板 2上的投影内。
由于桥接线 142可以为透明导电线或不透明电极线，且桥接线 142位于 与尺寸相对较大的黑矩阵 11相对应的区域， 因此， 工艺更加容易， 这样既 不影响像素的开口率， 也不会影响光线的透过率。
较佳地， 图 5所示的触摸驱动电极单元 141和触摸感应电极 15之间保 持绝缘的狭缝位于与所述黑矩阵相对应的区域。这样的设置方式即不影响像 素的开口率， 也不会影响像素显示区域光线的透过率。
较佳地， 所述第一电极和第二电极为透明导电电极， 例如可以但不限于 为铟锡氧化物 ITO或铟辞氧化物 IZO导电电极等。
所述桥接线可以但不限于为 ITO或 IZO电极， 或金属电极， 如铝、 相、 银或铂电极或由铝、 相、 银、 铂等中的至少两种金属的合金制成的电极。 本发明实施例提供的触摸驱动电极（或触摸感应电极）为包括相互独立 的多个触摸驱动电极单元（或触摸感应电极单元）。 然而， 通过桥接线连接 会增加触摸驱动电极（或触摸感应电极）的电阻， 不利于提高触摸屏的触控 效果。 为了降低触摸驱动电极的电阻， 提高其导电性能， 本发明实施例提供 的触摸屏还可以在触摸驱动电极或触摸感应电极上设置导电性较好的条状 金属电极， 或者可以在触摸驱动电极和触摸感应电极上设置导电性较好的条 状金属电极。
由于金属电极相比较金属氧化物导电电极的导电性更好， 因此导电性较 好的触摸驱动电极和触摸感应电极有利于提高触摸屏的触控效果。
即在图 3或图 4所示的触摸屏上设置条状金属电极。 触摸屏结构如图 7 所示， 其中， 在触摸驱动电极 14上设置多个条状金属电极 17。 为了进一步 降低触摸感应电极 15的电阻， 提高其导电性， 也可以在触摸感应电极 15上 设置多个条状金属电极 17。
为了不影响触摸屏的像素的开口率和光线的透过率， 较佳地， 所述条状 金属电极位于与所述黑矩阵相对应的区域。
所述条状金属电极可以为导电性较佳的铝、 相、 银或铂等导电电极， 或 者为由铝、 相、 银或铂等金属中至少两种金属的合金制成的电极。
较佳地，本发明所述触摸驱动电极和触摸感应电极可以为独立设置的电 极， 也可以为与其他可导电的膜层共用的电极。
在一个实施例中， 当内嵌式触摸屏的液晶显示屏为扭曲向列 （Twisted Nematic, TN )模式或垂直取向 （ Vertical Alignment, VA )模式的液晶显示 面板时， 公共电极设置在第一基板上， 即， 触摸驱动电极和触摸感应电极为 设置在第一基板上的公共电极，或者触摸驱动电极和触摸感应电极之一为设 置在第一基板上的公共电极。 触摸驱动电极和触摸感应电极分时驱动， 在图 像显示阶段， 同时为触摸驱动电极和触摸感应电极施加恒定电压 （V∞m ), 在触控阶段， 分别为触摸驱动电极和触摸感应电极施加实现触摸功能的触控 信号电压， 从而实现触摸功能。
在另一实施例中，触摸驱动电极和触摸感应电极其中之一为可导电的黑 矩阵。 具体地， 所述黑矩阵包括沿第一方向分布的第一部分， 以及沿第二方 向分布的第二部分。 所述黑矩阵的第一部分或所述第二部分可导电。 所述触 摸驱动电极可以作为所述可导电的黑矩阵的第一部分； 所述触摸感应电极可 以作为所述可导电的黑矩阵的第二部分。 或者， 所述触摸感应电极可以作为 所述可导电的黑矩阵的第一部分； 所述触摸驱动电极可以作为所述可导电的 黑矩阵的第二部分。
本发明实施例提供的触摸屏通过分时驱动的方式来实现图像显示和触 摸功能， 从而能够不影响触摸屏实现图像显示和触摸的功能。
需要说明的是， 本发明实施例提供的触摸屏， 第一基板以及其上的功能 结构构成彩膜基板， 第二基板用于形成阵列基板。 本发明实施例提供的触摸 屏仅是为了说明本发明的触摸驱动电极和触摸感应电极， 在具体实施过程 中， 触摸屏还包括其他功能结构， 例如， 在触摸驱动电极和触摸感应电极上 还可以设置有取向膜层（PI层）。
以上以触摸驱动电极和触摸感应电极设置在第一基板 (即彩膜基板）上 为例说明， 以下筒单说明触摸驱动电极和触摸感应电极设置在第二基板（阵 列基板）上的实施方式。
阵列基板包括薄膜晶体管 TFT像素阵列，本发明的触摸驱动电极和触摸 感应电极可以为单独设置的一层电极，也可以为与其他可导电的膜层共用的 电极。
当触摸驱动电极和触摸感应电极为单独设置的一层电极时，触摸驱动电 极和触摸感应电极与阵列基板上可导电的膜层相绝缘。
当触摸驱动电极和触摸感应电极为与其他可导电的膜层共用的电极时， 触摸驱动电极和触摸感应电极可以作为设置在阵列基板上的公共电极。或者 触摸驱动电极和触摸感应电极之一作为设置在阵列基板上的公共电极。
需要说明的是，将公共电极设置在阵列基板上的显示屏可以为平面方向 转换（In-Plane-Switching, IPS )模式和高级超维场转换（ADvanced Super Dimension Switch, ADS )模式的显示屏等。
图 8为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 8中，V-sync为时序信号。图 8还示出了 n条栅线，分别为栅线 1( Gate
1 )、 栅线 2 ( Gate 2 ) 栅线 m ( Gate m )、 栅线 m+1 ( Gate m+1 )、 栅线 m+2 ( Gate m+2 )、栅线 m+3 ( Gate m+3 )、栅线 n-1 ( Gate n-1 )、栅线 n ( Gate n )。 还包括数据线 Date, n条触摸驱动电极 (Tl、 T2, , Τη)的时序， 以及 η条触摸感应电极（Rl、 R2, , Rn ) 的时序。
假设显示一帧图像的时间为 16.7ms, 如图 8所示， 前 11.7ms为图像显 示阶段， 后 5ms为触控阶段。 在具体实施过程中， 前 11.7ms内依次为栅线 施加栅电压， 同时依次为数据线施加数据信号， 实现图像显示。 后 5ms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。依次为触摸驱 动电极 Tx施加一定触摸驱动电压 Vi , 以及同时为触摸感应电极施加恒定电 压或交流电压 V。。在施加有电压 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， 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。
需要说明的是， 本发明实施例提供的内嵌式触摸屏， 可以集成在 TN模 式的液晶显示面板中， 或集成在高级超维场转换 （ADS , Advanced Super Dimension Switch )模式的液晶显示面板中。 ADS模式是平面电场宽视角核 心技术， 其核心技术特性描述为： 通过同一平面内狭缝电极边缘所产生的电 场以及狭缝电极层与板状电极层间产生的电场形成多维电场，使液晶盒内狭 缝电极间、 电极正上方所有取向液晶分子都能够产生旋转， 从而提高了液晶 工作效率并增大了透光效率。 ADS模式的开关技术可以提高 TFT-LCD产品 的画面品质， 具有高分辨率、 高透过率、 低功耗、 宽视角、 高开口率、 低色 差、 无挤压水波纹（push Mura )等优点。 针对不同应用， ADS技术的改进 技术有高透过率 I-ADS技术、 高开口率 H-ADS和高分辨率 S-ADS技术等。
