垂直设置且相互绝缘的触控发射线 101和触控感应线 102, 每条触控发 射线 101和每条触控感应线 102均形成一个触控感应电容； 且
每条触控发射线 101或触控感应线 102在基板上的投影均落入栅线或者 数据线在所述基板上的投影中。 由于每条触控发射线 101或触控感应线 102在基板上的投影均落入栅线 或者数据线在所述基板上的投影中， 并通过将触控发射线 101和触控感应线 102垂直设置并相互绝缘， 在触控发射线 101和触控感应线 102的异面相交 处构成了触控感应电容， 当对显示装置进行触控时， 对显示装置的触摸导致 相应位置的触控感应电容的电容值变化， 使得相应的触控感应线 102输出感 应信号， 实现触控感应， 避免了设置影响像素开口率的像素开关， 增大了触 控显示装置的开口率。
为便于进行控制， 通常将触控发射线 101设置为沿同一方向延伸， 将触 控感应线 102设置为沿另一方向延伸， 例如， 触控发射线 101在基板上的投 影可以均落入栅线在所述基板上的投影中， 触控感应线 102在基板上的投影 可以均落入数据线在所述基板上的投影中； 或者， 触控感应线 102在基板上 的投影可以均落入栅线在所述基板上的投影中， 触控发射线 101在基板上的 投影可以均落入数据线在所述基板上的投影中。
即， 每条触控发射线 101或触控感应线 102在基板上的投影均落入栅线 或者数据线在基板上的投影中， 具体为：
每条触控发射线 101在基板上的投影均落入栅线在基板上的投影中，且, 每条触控感应线 102在基板上的投影均落入数据线在基板上的投影中； 或者 每条触控感应线 102在基板上的投影均落入栅线在基板上的投影中，且, 每条触控发射线 101在基板上的投影均落入数据线在基板上的投影中。
通常， 对于很多显示装置来讲不需要对应每个像素单元均设置一条触控 发射线 101和一条触控感应线 102, 在一定范围内设置一条触控发射线 101 和一条触控感应线 102即可， 即， 每第一设定个数的像素单元对应一条触控 发射线， 且， 每第二设定个数的像素单元对应一条触控感应线， 该第一设定 个数和第二设定个数可以设置为 15~25, 此时， 可以在保证触控灵敏性的同 时， 避免触控发射线 101和触控感应线 102设置过于密集导致的不必要的损 耗。 通常， 可以设计为第一设定个数与第二设定个数相同， 例如， 第一设定 个数和第二设定个数均为 20。
本发明实施例提供的一种实现方式是： 将触控发射线 101和触控感应线 102设置在不同层中， 且触控发射线 101所在的层和触控感应线 102所在的 层之间设置有绝缘层。 进一步， 本发明实施例的阵列基板还可以包括： 多个金属导线矩阵， 分 别与每条触控发射线 101和触控感应线 102相连接并且在基板上的投影落入 栅线和数据线在基板上的投影中， 一个金属导线矩阵与一条触控发射线 101 或一条触控感应线 102相连， 以辅助该触控发射线 101或触控感应线 102的 传输， 减小该触控发射线 101或触控感应线 102的传输阻抗， 进而减小传输 损耗， 同时也能增大触控面积， 提高灵敏度。
该金属导线矩阵中的金属导线可以与栅线和数据线——对应， 从而获得 更佳的传输效果， 也可以在数量上少于栅线和数据线， 进而减小工艺难度。
如图 2a和图 2b所示， 加粗的线条分别是触控发射线 101和触控感应线 102, 其它线条是金属导线， 由于触控发射线 101和触控感应线 102设置在不 同的层中， 所以触控发射线 101和触控感应线 102、 触控发射线 101连接的 金属导线和触控感应线 102、 触控发射线 101连接的金属导线和触控感应线 102连接的金属导线、 触控发射线 101和触控感应线 102连接的金属导线， 均是相互绝缘的。
为了减少工艺流程， 减小工艺复杂度， 同时减小阵列基板的厚度， 本发 明实施例提供的另一实施方式为： 将触控发射线 101和触控感应线 102设置 在同一层中。
例如， 如图 3所示， 触控发射线 101包括发射线部分 1011和桥线部分 1012, 并由该桥线部分 1012与触控感应线 102形成触控感应电容， 发射线部 分 1011与触控感应线 102设置在同一层， 桥线部分 1012为投影覆盖该触控 发射线在基板的投影的栅线或数据线，发射线部分和桥线部分通过过孔连接; 或者
如图 4所示， 触控感应线 102包括感应线部分 1021和桥线部分 1022, 并由该桥线部分 1022与触控发射线 101形成触控感应电容，感应线部分 1021 与触控发射线 101设置在同一层， 桥线部分 1022为投影覆盖该触控感应线 102在基板的投影的栅线或数据线， 感应线部分 1021和桥线部分 1022通过 过孔连接。
以触控发射线 101包括发射线部分 1011和桥线部分 1012为例， 在阵列 基板中， 沿图 3中的任意一条虚线进行截面的截面图如图 5所示， 该截面图 包括如图 3中的一条虚线 （桥线部分）及该虚线两端的发射线部分。 为进一步增大开口率， 过孔在基板上的投影落入黑矩阵在基板上的投影 中， 为降低工艺难度， 可以使得黑矩阵较宽的方向上的触控发射线 101或触 控感应线 102,分为发射线部分 1011和桥线部分 1012或分为感应线部分 1021 和桥线部分 1022。
进一步， 为了减小传输阻抗， 本发明实施例的阵列基板还包括： 多个金 属导线矩阵，
每个金属导线矩阵与一个发射线部分 1011或一条触控感应线 102相连接 并且在基板上的投影落入栅线和数据线在基板上的投影中； 或者
每个金属导线矩阵与一个感应线部分 1021或一条触控发射线 101相连接 并且在基板上的投影落入栅线和数据线在基板上的投影中。
由图 3中可以看出， 与触控感应线 102相连接的金属导线矩阵纵向连续 延伸， 与各发射线部分 1011相连接的金属导线矩阵则在横向由触控感应线 102及与触控感应线 102相连接的金属导线矩阵断开。
由图 4中可以看出， 与触控发射线 101相连接的金属导线矩阵横向连续 延伸， 与各感应线部分 1021相连接的金属导线矩阵则在纵向由触控发射线 101及与触控发射线 101相连接的金属导线矩阵断开。
由于在该实施方式中， 触控发射线 101或触控感应线 102中包括了栅线 或数据线的一部分， 所以为了避免显示和触控互相干扰， 可以令阵列基板的 显示驱动和触控驱动分时段进行， 对应如图 3所示的电路结构， 且每 20个像 素单元对应一条触控发射线 101、每 20个像素单元对应一条触控感应线 102, 其时序如图 6所示， 在第一阶段进行显示驱动， 只有栅线（Gate )传输信号， 在第二阶段进行触控驱动， 栅线和触控发射线 101 ( Tx )相连， 所以发射同 样的时序信号， 触控感应线 102 ( Rx )进行信号输出， 在相应的触控感应电 容被触动导致电容值变化时， 触控感应线 102输出的信号相应发生变化， 进 而可以定位被触动的触控感应电容位置， 实现触摸控制。
本发明实施例还相应提供一种触控显示装置， 包括本发明实施例提供的 阵列基板。
本发明实施例提供一种阵列基板及触控显示装置， 其包括相互垂直设置 且绝缘的多条触控发射线和多条触控感应线， 每条触控发射线和每条触控感 应线均形成一个触控感应电容， 通过触控时感应电容的电容值变化即可实现 触控感应， 同时， 每条触控发射线或触控感应线在基板上的投影均落入栅线 或者数据线在基板上的投影中， 增大了触控显示装置的开口率。 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。
