Description

触控显示面板、 触摸定位方法和显示装置 技术领域
本发明的实施例涉及一种触控显示面板、 触摸定位方法和显示装置。 背景技术
随着智能移动终端的发展， 具有触摸功能的移动终端被越来越多的用户 所青睐。 目前， 主要采用 add on和 on cell两种方式来在显示装置中实现触摸 功能。 Add on方式是指将单独的触摸面板贴合在显示面板上， 形成整体上具 有显示功能和触控功能的显示装置。 On cell方式是指将实现触摸功能的部件 嵌入到彩色滤光片基板和位于彩色滤光片基板背侧的偏光板之间。 但是， 这 两种方式均需要借助外置功能模块来实现触摸功能、或者需要后期加工处理， 因此采用这两种方式制作的具有触摸功能的移动终端在制作成本和制作周期 上都没有优势。
近来， 又提出了一种将触控功能模块集成在薄膜场效应晶体管 （TFT, Thin Film Transistor )阵列基板上的 in cell方式， 以提高具有触摸功能的显示 装置的集成度。 In cell方式是指将实现触摸功能的部件嵌入到显示装置的像 素中。 例如， in cell方式的基本原理如下： 在 TFT阵列基板上增加用于触控 的扫描线（即触控扫描线） ， 并在其上施加周期性扫描信号； 在彩膜（CF ) 基板的黑矩阵中形成触控感应线，该触控感应线和上述触控扫描线相互垂直； 在 TFT阵列基板上的触控扫描线上形成触控电容，通过触控电容将扫描信号 传输至触控感应线， 以由此判断触控发生的位置。
但是， 在该 in cell方式中， TFT阵列上增加了专门的触控扫描线， 占用 了较大的空间， 对于像素开口率的提升不利。 另外， 触控感应线用具有导电 功能的黑矩阵来制作， 由于黑矩阵在 CF基板上是一体化形成， 所以触控感 应线之间的干扰或者短路是不可避免的， 这无疑大大降低了触控感应的识别 效率。 发明内容 根据本发明的一个实施例， 提供一种触控显示面板。 该触控显示面板包 括具有栅线的薄膜场效应晶体管（TFT )阵列基板和具有黑矩阵的对置基板。 将至少一条所述栅线设置为触控扫描线。 在所述对置基板的黑矩阵上设置至 少一条触控感应线。 在所述触控扫描线和所述触控感应线相交处形成触控电 谷。
根据本发明的另一个实施例， 提供一种显示装置。 该显示装置包括上述 的触控显示面板。
根据本发明的再一个实施例， 提供一种触摸定位方法。 该方法采用上述 的触控显示面板， 该方法包括：
向所述触控扫描线加载扫描信号；
检测所述触控感应线的电压信号；
才艮据检测到的电压信号和向触控扫描线加载的扫描信号确定与触摸位置 相对应的触控扫描线和触控感应线；
才艮据确定的触控扫描线和触控感应线的相交点确定触摸位置。
根据本发明的实施例， 不需要设置专门的触控扫描线， 仅通过 TFT阵列 基板上原有的栅线即可提供触控扫描线的功能。 如此， 就可以避免传统技术 中在 TFT 阵列基板上增加专门的触控扫描线而产生的对像素开口率提升不 利的问题。 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为根据本发明实施例的触控显示面板的立体示意图；
图 2为根据本发明实施例的触控显示面板的截面示意图。 具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图， 对本发明实施例的技术方案进行清楚、 完整地描述。 显然， 所描述的实施例 是本发明的一部分实施例， 而不是全部的实施例。 基于所描述的本发明的实 施例， 本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实 施例， 都属于本发明保护的范围。
本发明的实施例提供一种触控显示面板，不需要设置专门的触控扫描线， 仅通过 TFT阵列基板上原有的栅线即可实现触控扫描线的功能。 如此， 可以 避免传统技术中在 TFT 阵列基板上设置专门的触控扫描线而产生的对像素 开口率提升不利的问题。
图 1为根据本发明实施例的触控显示面板的立体示意图。 如图 1所示， 该触控显示面板由 TFT阵列基板 1和对置基板 2贴合而成。对置基板 2例如 为彩膜基板。 本发明的实施例中， 将 TFT阵列基板 1上的至少一条栅线设置 为触控扫描线 3,在对置基板 2的黑矩阵上设置至少一条触控感应线 4,并在 触控扫描线 3和触控感应线 4交叉的位置处形成触控电容 5。 这里， 触控扫 描线 3和触控感应线 4为异面交叉。 优选地， 触控感应线 4的延伸方向与触 控扫描线 3 (即， 栅线） 的延伸方向垂直。
图 2为根据本发明实施例的触控显示面板的截面示意图。 如图 2所示， 触控感应线 4设置在对置基板 2下表面 （朝向 TFT阵列基板 1 ) 的黑矩阵 9 上。 优选地， 在触控感应线 4的表面上设置第一导电层 8, 且第一导电层 8 和触控触控感应线 4之间形成有填充物 12。 优选地， 第一导电层 8与对置基 板 2上的公共电极 10采用相同的材料制成，并在同一次制作工艺中形成。例 如， 第一导电层 8与对置基板 2上的公共电极 10均采用透明导电材料形成， 例如氧化铟锡（ΙΤΟ )等。 在对置基板 2上还设置有填充物 11 , 该填充物 11 通常为起支撑作用的隔垫物。 优选地， 填充物 12与填充物 11采用相同的材 料制成， 并在同一制作工艺中形成。 从图 2可以看出， 触控感应线 4与黑矩 阵 9重叠， 呈线状排列， 并与触控扫描线 3 (即， 栅线） 的延伸方向垂直相 交。
黑矩阵 9采用绝缘材料制成， 例如树脂材料等。 如此， 能够避免触控感 应线 4之间的干扰或者短路。
如图 2所示， 在 TFT阵列基板 1的上表面 （朝向对置基板 2 )上设置有 第二导电层 7, 该第二导电层 7位于触控感应线 4与触控扫描线 3的交叉位 置处。第一导电层 8在对置基板 2上的位置与第二导电层 7在 TFT阵列基板 1上的位置相对应。 优选地， 第二导电层 7和 TFT阵列基板 1上的像素电极 采用相同的材料制成， 且在同一制作工艺中形成。
在本发明的实施例中， 在一个触控区域中只形成一个触控电容 5 , —个 触控区域包括至少一个像素。 优选地， 一个触控区域包括多个像素。 在一个 触控区域包括多个像素的情况下， 可以在该触控区域中任选一个像素， 进一 步地从该选择的像素中任选一个亚像素， 将该选择的亚像素所对应的栅线用 作触控扫描线 3且在触控扫描线 3和第二导电层 7之间形成触控电容 5。 优 选地， 上述任选的一个亚像素为蓝色亚像素。 由于触控电容 5会影响像素的 开口率， 当选择蓝色像素时对显示装置的亮度等光特性影响最小。
当如上所述的触控显示面板被触摸按压时， 位于触摸位置处的触控扫描 线 3和第二导电层 7之间的触控电容 5发生变化。 由于触控电容 5的变化， 当来自触控扫描线 3的扫描信号经由触控电容 5传输至触控感应线 4时该扫 描信号也发生变化， 触控感应线 4将该变化作为检测信号输出， 从而可以确 定触摸的位置。 可以根据需要设置第一导电层 8的厚度和第二导电层 7的厚 度， 以使得当触控显示面板被触摸按压时位于触摸位置处的第一导电层 8和 第二导电层 7接触。 此时， 触控扫描线 3提供的扫描信号通过触控电容 5、 第二导电层 7和第一导电层 8传输至触控感应线 4。
另外， 在本发明的实施例中， 以包括多个像素的触控区域为单位进行触 控电容 5的设置的原因如下。 在触摸物例如手指等触摸触控显示面板时， 触 控显示面板的受力面积较大。 如果以包括单个像素的触控区域为单位进行触 控电容 5的设置， 那么受力面积会覆盖多个触控电容 5 , 而在该受力面积下 对于触摸位置的感应只需要一个触控电容 5即可。 这样， 就会造成很大程度 的资源浪费， 占用较多的面板空间， 因此， 本发明的实施例基于可能的受力 面积进行了触控区域的划分， 并且优选地一个触控区域包含多个像素。
为了更精确地确定触摸位置， 优选地， 对置基板 2上的每个黑矩阵 9对 应一根触控感应线 4, 即触控感应线 4的数量与 TFT阵列基板 1上的数据线 的数量相等，并且触控感应线 4的位置与 TFT阵列基板 1上的数据线的位置 ——对应。 这样， 可以保证对置基板 2与 TFT阵列基板 1对盒后， 触控感应 线 4的位置与 TFT阵列基板 1上的数据线的位置重叠，从而不影响触控显示 面板的开口率。
本发明的实施例还提供了一种包括上述触控显示面板的显示装置。 该显 示装置可以是显示器、 手机、 电视、 笔记本电脑等。 对于本领域普通技术人 员所熟知的显示装置所具有的其它必不可少的组成部分在此不做赘述。
基于上述触控显示面板， 本发明的实施例还提供了一种触摸定位方法。 该方法包括如下步骤。
步骤 301 , 向触控扫描线加载扫描信号；
步骤 302, 检测触控感应线的电压信号；
步骤 303, 根据检测到的电压信号和向触控扫描线加载的扫描信号确定 与触摸位置相对应的触控扫描线和触控感应线；
步骤 304,根据确定的触控扫描线和触控感应线的相交点确定触摸位置。 例如， 上述方法的详细过程如下。
1、 对触控扫描线 3 (即栅线）以固定周期加载扫描信号， 该扫描信号的 大小为打开亚像素的 TFT的电压大小。 例如， 该扫描信号可以为具有固定周 期的时钟信号。 优选地， 固定周期可以与栅极逐行扫描信号的周期相同。 当 然， 也可以根据实际需求设置一个专门的周期， 只要能够保证不影响栅线的 正常扫描并保证能够实时感应到触控即可。
2、 当触控显示面板被触摸时，受力范围内的第一导电层 8与第二导电层 7接触， 则触控扫描线 3上的扫描信号通过触控电容 5传输至触控感应线 4。
3、检测触控感应线 4输出的信号，结合向触控扫描线 3加载扫描信号的 时钟，可以确定出相应的触控扫描线 3,进而根据该输出信号的触控感应线 4 和确定的触控扫描线 3形成的交叉点来确定触摸位置。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
