显示器的触摸技术按照原理划分大体有以下几种： 电阻式触摸屏、 电容 式触摸屏、 红外线式触摸屏、 表面声波式触摸屏、 电磁式触摸屏、 振波感应 式触摸屏、 受抑全内反射光学感应式触摸屏等； 按照组成结构分有以 F: 外 挂式 (out-cell)触摸屏、 触摸传感在显示面板上面 (on-cell)的触摸屏以及触摸传 感在显示面板内部 (in-cell)的触摸屏等。
随着市场要求， 显示装置的整体模组减薄是市场发展趋势， 所以触摸结 构由触摸传感外挂式向触摸传感做到面板内部 (in-cell)的实现方式发展 , 同时 由于减少了一部分制作工序， 还能够达到降低触摸屏幕制作成本的目的。
目前比较成熟的一种技术是所谓的 OGS技术， OGS的全称是 One Glass Solution, 也即单层玻璃解决方案， 其属于 on-cell方案的一种， 将触摸屏幕和 保护玻璃结合实现触控操作， 但该技术还无法实现在 TFT阵列基板上的像素 内部嵌入触摸传感功能。 OGS技术采用互电容工作原理， 其基本原理为先制 作相邻的两个导体，在相邻的导体之间存在固定电容， 当另一个导体 (如手指：) 靠近两个导体之间的位置时， 便会造成感应电容并联到固有电容上， 造成整 体的电容增加， 拿开手指后， 电容又减小， 后端驱动侦测有无手指时电容的 变化， 判断出面是否存在面板接触及接触位置。
然而对于 In-cell技术来说， 由于需要在 TFT (薄膜晶体管) 阵列基板上 的像素内部嵌入触摸传感功能， 使得半导体制造工艺复杂， 因此难以确保成 品率和显示性能， 实用化未取得进展。 发明内容

以下结合附图对本发明的结构和原理进行详细说明， 所举实施例仅用于 解释本发明， 并非以此限定本发明的保护范围。
本发明具体实施例所述阵列基板、 触控显示面板及显示装置， 利用阵列 基板上的数据线 （Data) 和栅线 ( Gate ) 实现触控功能， 实现显示面板触控 结构的 In-cell方式， 且无需额外增加制作工艺， 因此制作简单方便， 能够达 到降低触摸显示面板厚度及制作成本的目的。

图 1为本发明所述阵列基板用于实现上述显示及触控功能的电路结构示 意图。
参阅图 1 所示， 与现有技术薄膜场效应晶体管 （TFT) 液晶显示器阵列 基板的像素电路相似， 所述阵列基板包括多个平行设置的数据线 10、 多个平 行设置的栅线 20， 且数据线 10与栅线 20相互垂直、 彼此交叉， 形成为多个 由红色 （R)、 绿色 （G) 或蓝色 （B ) 子像素构成的像素单元， 每一子像素 30内设置有驱动薄膜晶体管 31和像素电极 33。
此外， 在阵列基板的边缘设置有：
数据线驱动芯片（Data IC) 40， 用于向各数据线 10输入数据扫描信号; 栅线驱动芯片 （Gate IC) 50， 用于向各栅线 20输入栅扫描信号。
上述结构像素电路构成的阵列基板中， 用于图像显示的驱动方法为， 通 过数据线驱动芯片 40在一帧时间里依次向每一数据线 10输入数据扫描信号， 通过栅线驱动芯片 50依次向每一栅线 20输入栅扫描信号， 使每一子像素 30 上的驱动薄膜晶体管 31根据所对应栅线 20上的栅扫描信号以及数据线 10的 数据扫描信号导通或断开， 以实现不同图像显示。 本领域技术人员应该能够 理解上述图像显示的电路驱动方法， 且该部分并非为本发明的技术重点， 在 此不详细描述。
为了能够在阵列基板上实现触控功能， 本发明实施例所述的阵列基板上 还进一歩包括： 用于触控定位的触控定位电路单元， 其中将所述阵列基板上 的栅线 20和数据线 10分别作为触控感应线或触控发射线。
如图 1所示， 所述触控定位电路单元还包括：
信号发射驱动芯片 （ Touch ICCTX)) 60， 用于向触控发射线输入触控感 应信号； 和
信号接收驱动芯片 （T uch IC(RX)) 70， 用于接收触控感应线上的触控 感应信号。
本发明实施例中， 用于触控定位的触控发射线利用了栅线 20实现， 用于 触控定位的触控感应线利用了数据线 10实现， 但并不限于此， 触控发射线也 可以为数据线 10， 则同时触控感应线可以为栅线 20。
此外， 参阅图 1所示， 所述触控定位电路单元还包括用于使数据线 10和 »线 20分别在图像显示功能和触控定位功能之间切换的触控开关电路，具体 地， 所述触控开关电路包括：
第一开关电路 80， 用于接收第一信号 Sl， 使数据线 10与数据线驱动芯 片 40之间、 »线 20与栅线驱动芯片 50之间在第一阶段导通并在第二阶断断 开； 其中第一阶段中数据线 10和栅线 20分别用于图像显示功能， 在第二阶 段中数据线 10和栅线 20分别用于定位触控功能；
第二开关电路 90， 用于接收第二信号 S2， 使信号发射驱动芯片 60与触 控发射线之间、信号接收驱动芯片 70与触控感应线之间在第一阶段断开并在 所述第二阶断导通。
参阅图 1所示， 所述第一开关电路 80具体包括: 用于根据所述第一信号 S1导通或断开的多个第一开关晶体管 81和多个第二开关晶体管 82， 其中每 一所述数据线 10通过一个所述第一开关晶体管 81与所述数据线驱动芯片 40 连接， 每一所述栅线 20通过一个所述第二开关晶体管 82与所述 »线驱动芯 片 50连接。
其中， 如图 1所示， 所述第一开关晶体管 81 的栅极与所述第一信号 S1 的输入端连接， 漏极与所述数据线驱动芯片 40连接， 源极与所述数据线 10 连接； 所述第二开关晶体管 82的栅极与所述第一信号 S1的输入端连接， 漏 极与所述栅线驱动芯片 50连接， 源极与所述栅线 20连接。
所述第二开关电路 90具体包括： 用于根据所述第二信号 S2导通或断开 的多个第三开关晶体管 91和多个第四开关晶体管 92， 其中每一所述触控发 射线 (本实施例中为栅线 20)通过一个所述第三开关晶体管 91与所述信号发射 驱动芯片 60连接， 每一所述触控感应线 （本实施例中为数据线 10) 通过一 个所述第四开关晶体管 92与所述信号接收驱动芯片 70连接。
其中， 如图 1所示， 所述第三开关晶体管 91 的栅极与所述第::：::信号 S2 的输入端连接， 漏极与所述信号发射驱动芯片 60连接， 源极与所述触控发射 线 (本实施例中为栅线 20)连接; 所述第四开关晶体管 92的栅极与所述第:二信 号 S2的输入端连接， 漏极与所述信号接收驱动芯片 70连接， 源极与所述触 控感应线 （本实施例中为数据线 10) 连接。
上述实施例中， 以 N沟道 TFT (薄膜晶体管） 为例进行了图示， 然而， 本领域的技术人员应当明白,也可以以 P沟道 TFT作为各开关晶体管。此外， 由于 TFT的源极、 漏极的结构存在相似性， 可以理解， 将源极和漏极互相置 换的做法也是本发明上述实施例的等同替代方式。
采用上述结构， 在图像显示的一帧时间里， 可以分为以下两个阶段， 如 图 2所示为 N沟道 TFT的情况下进行图像显示及触控的时序控制图， 其中： 在第一阶段， 也即图像显示的充电阶段， 第一信号 S1为高电平， 第二信 号 S2为低电平， 使得第一开关晶体管 81和第二开关晶体管 82分别打开， 而 第三开关晶体管 91和第四开关晶体管 92分别关闭。 因此， 数据线驱动芯片 40依次向每一数据线 10输入数据扫描信号， 栅线驱动芯片 50依次向每一栅 线 20输入栅扫描信号， 并给子像素 30的像素电极 33充电， 用于图像显示。
在第二阶段， 也即触控阶段， 第一信号 S1为低电平， 第二信号 S2为高 电平， 使得第一开关晶体管 81和第二开关晶体管 82分别关闭， 而第三开关 晶体管 91和第四开关晶体管 92分别打开。 此时， 用于触控定位的信号发射 驱动芯片 60和信号接收驱动芯片 70开始工作，信号发射驱动芯片 60用于分 别给每一触控发射线 (本实施例中为栅线 20)输入触控感应信号， 而信号接收 驱动芯片 70用于接收触控感应线 (本实施例中为数据线 10)上当有触控操作时 的电压变化信号。
在第:二阶段也即触控阶段时的等效电路可以形成为图 3所示结构， 利用 栅线 20和数据线 10用于触控操作的工作原理与现有技术采用 OGS实现触控 的原理相同， 也即形成为互电容原理： 在相邻的导体之间存在固有电容， 当 另一个导体 (如手指：)靠近两个导体之间的位置时，便会造成感应电容并联到固 有电容上， 造成整体的电容增加， 拿开手指后， 电容又减小， 因此通过侦测 有无手指时固有电容的变化， 即能够判断出是否存在触控接触及具体的接触 位置。
依据本发明实施例， 所述栅线 20形成为用于触控定位的触控发射线， 也 即驱动电极 （Tx) ; 所述数据线 10形成为用于触控定位的触控感应线， 也即 接收电极 (Rx); 当驱动电极与接收电极以行、 列交叉方式设置时， 通过信号 发射驱动芯片 60依次向每一触控发射线输入触控感应信号，信号接收驱动芯 片 70分别获得每一触控感应线的触控感应信号， 由于触控发射线与触控感应 线相对的截面之间存在固有电容， 当手指靠近时， 会引起信号接收驱动芯片 70获得的触控感应信号变化， 因此能够判断出是否存在触控接触及具体的接 触位置， 实现触控定位。
此外， 本发明实施例中， 在第二阶段也即触控阶段时， 为了保持显示画 面的正常显示， 各子像素 30上的驱动薄膜晶体管 31应该处于关闭状态， 因 此信号发射驱动芯片 60 向触控发射线 （本实施例中也即栅线 20) 所发出控 制信号的电压应该远远小于驱动薄膜晶体管 31的开启电压，使各驱动薄膜晶 体管 31处于关闭状态， 此时， 由于通常在各个像素中设置有保持电容， 可以 保持像素电极 33与公共电极（图中未显示）之间的电压不变， 从而可维持正 常显示。 另一方面， 由于信号发射驱动芯片 60向触控发射线所发出的控制信 号的电压较小， 使得各子像素的像素电极 33不受触控定位的影响。
在一个优选实施例中， 所述数据线 10 形成为用于触控定位的触控发射 线， 也即驱动电极 （Tx); 所述栅线 20形成为用于触控定位的触控感应线， 也即接收电极 (RX)。 这种情况下， 由于栅线 20作为用于触控定位的触控感应 线， 其上的电压很低， 无法打开各个像素中的 TFT， 此时， 即使作为触控发 射线的数据线上出现较高电压， 也无法传递到像素电极 33， 从而可以保证各 个像素的正常显示。
此外， 结合图 6所示， 所述各个子像素 30还包括存储电容 Cs， 用于在 第二阶段内维持所述像素电极 33的电压。
本发明实施例中， 如图 1所示， 阵列基板上的每-一数据线 10和栅线 20 均形成为用于触控定位的所述触控感应线或者所述触控发射线， 然而图 1仅 为用于说明本发明的原理， 利用数据线和栅线形成为所述触控感应线或者所 述触控发射线的方式并不限于该一种， 由于触控显示面板上， 用于触控定位 的分辨率远小于图像显示的分辨率， 因此不限于每一行数据线和栅线均用于 形成为所述触控感应线或者所述触控发射线， 也可以为： 每间隔 N行的所述 数据线形成为所述触控感应线或者所述触控发射线， 每间隔 M行的所述栅线 形成为所述触控发射线或者所述触控感应线， 其中 N和 M均大于等于 1， 且 N与 M可以相同也可以不同。 例如， 每间隔 3行的数据线形成为所述触控感 应线， 或者每间隔 3行的栅线形成为触控发射线。
另外， 本发明实施例的另一方面， 也可以是多行的数据线和 /或栅线形成 为用于触控定位的一个触控功能线。 如图 5所示， 给出了本发明实施例的另 一种方式， 其中每相邻两行数据线形成为一个触控感应线， 每相邻两行栅线 形成为一个触控发射线， 实际应用中， 也不限于此， 也可以是更多行的数据 线或栅线形成为用于触控定位的触控功能线。
此外， 本发明上述实施例中， 以所有栅线 20形成为触控发射线， 所有数 据线 10形成为触控感应线进行了说明， 如上所说明的， 所有栅线 20也可以 形成为触控感应线， 所有数据线 10可以形成为触控发射线， 在用作触控定位 时， 依据图 1所示形式， 将两者的功能互换， 除此之外， 在整个阵列基板上， 也可以存在一部分的栅线 20形成为触控发射线，一部分的数据线形成为对应 的触控感应线； 而剩余另一部分栅线 20形成为触控感应线， 剩余另一部分的 数据线 10形成为对应的触控发射线的情况， 如图 4所示， 以满足多种不同的 线路布局要求。
采用本发明具体实施例上述结构的阵列基板， 利用阵列基板上的数据线 (Data) 和栅线 （Gate) 实现触控功能， 制作工艺简单方便， 且数据输入信 号也非常好处理。
本发明具体实施例另一方面还提供一种包括上述阵列基板的触控显示面 板， 该触控显示面板可以为一通常的液晶显示面板， 包括彩膜基板及设置于 彩膜基板及阵列基板之间的液晶层， 其中彩膜基板、 阵列基板与液晶层之间 的安装方式与现有技术相同， 在此不详细描述。
利用本发明实施例的阵列基板， 无需额外设置触控感应层即能够实现显 示面板的触控功能， 制作工艺简单方便， 能够达到降低触摸显示面板厚度及 制作成本的目的。
此外， 本发明另一方面还提供一种包括上述触控显示面板的显示装置， 本领域技术人员根据本发明实施例上述阵列基板的具体结构， 应该能够了解 显示装置的结构， 在此不详细描述。
本发明的再一方面还提供一种采用上述阵列基板的电路驱动方法，包括: 在第一阶段， 向所述数据线输入数据扫描信号， 向所述栅线输入栅扫描 信号， 实现图像显示；
在第二阶段， 向作为所述触控发射线的所述数据线或所述栅线输入触控 感应信号，作为所述触控感应线的所述数据线或所述栅线接收触控感应信号， 实现触控定位。
此外， 在第二阶段也即触控阶段时， 为了保持显示画面的正常显示， 所 述阵列基板各子像素上的薄膜晶体管应该处于关闭状态， 因此向触控发射线 (栅线或数据线） 所发出控制信号的电压应该远远小于薄膜晶体管的开启电 压， 使各薄膜晶体管处于关闭状态。
本发明具体实施例所述阵列基板、 触控显示面板、 显示装置及电路驱动 方法， 利用阵列基板上的数据线 （Data) 和 »线 （Gate) 实现触控功能， 无 需额外增加制作工艺， 因此制作简单方便， 能够达到降低触摸显示面板厚度 及制作成本的目的。
以上所述为本发明较佳实施例， 应当指出， 对于本领域普通技术人员来 说， 在不脱离本发明所述原理的前提下， 还可以作出若干改进和润饰， 这些 改进和润饰也应视为本发明保护范围。
