续参照图3所示，在本实施例中，每一个子像素单元5还包含一显示电容56及一公共电容57，其中所述显示电容56电性连接所述薄膜晶体管54及相应的所述显示电极，所述公共电容57电性连接所述切换开关55及相应的所述公共电极。另外，在每一个子像素单元5中，相应的所述第一栅极线3以及相应的所述第二栅极线4分别排列在所述水平黑矩阵区52的相对二侧。
续参照图3所示，在本实施例中，所述第一栅极线3配置用以通过多个高频时脉信号来控制所述第一栅极线3的级传输出，另外，所述第二栅极线4配置用以通过一全局信号来进行控制，经由切换所述切换开关55，从而对所述公共电极进行充电。
续参照图3所示，在本实施例中，所述数据线2的一来源信号是由一第一时段、一第二时段及一第三时段组成，其中所述第一时段用于所述子像素单元5的薄膜晶体管54对于所述显示电极的一显示充电，所述第二时段为一触控时段，所述第三时段用于经由切换所述切换开关55，从而对所述公共电极进行充电。
另外，本发明一实施例提供的一种触摸显示屏，包括相对设置的上基板及下基板(未绘示)，还包括设置在所述下基板及/或所述上基板上的公共电极，所述公共电极与每一子像素单元一一对应且用于指纹识别。
要说明的是，本发明实施例提供的指纹识别利用自电容的原理，在有用户手指靠近感应电极时，由于手指皮肤表面具有凹凸不平的脊和谷，因此皮肤表面各点距离各感应电极的远近也不同，从而影响了感应电极与公共电极的电容值，造成在感应电极上的指纹识别信号充电时间延长，通过检测在手指碰触到感应电极的过程中，每个时刻各感应电极接收到的信号大小差异，就可以检测出对应手指由脊和谷构成的指纹二维图样，从而实现指纹识别。
通过上述的设计，将所述水平黑矩阵区52配置用以供相应的所述第一栅极线3以及相应的所述第二栅极线4走线，同时将所述薄膜晶体管54及所述切换开关55设置在所述水平黑矩阵区52中，另外将所述垂直黑矩阵区53配置用以供相应的数据线2走线，以节省芯片的数据线而缩减芯片尺寸，同时可减少侧边框宽度，进而提升屏占比，使得开口率可大幅度提升，以提高光透过率，达到高亮度目的。
配合参照图3及4所示，本发明提供一种阵列基板的驱动方法，所述方法包含对所述数据线2传送一来源信号，所述来源信号由一第一时段T1、一第二时段T2及一第三时段T3组成，其中所述第一时段T1用于所述子像素单元的薄膜晶体管的一显示充电，也就是显示时段，所述第二时段T2为一触控时段，所述第三时段T3用于经由切换所述切换开关55，从而对所述公共电极进行充电。在本实施例中，在所述第一时段T1及所述第二时段T2中，所述全局信号为低电平，使得所述第二栅极线4上的多个切换开关55同时关闭。另外，在所述第三时段T3中，所述全局信号为高电平，使得所述第二栅极线4上的多个切换开关同时打开。
如上所述，本发明阵列基板的驱动方法，可实现三种时序控制，以满足显示及触控的要求。另外，将所述水平黑矩阵区52配置用以供相应的所述第一栅极线3以及相应的所述第二栅极线4走线，同时将所述薄膜晶体管54及所述切换开关55设置在所述水平黑矩阵区52中，另外将所述垂直黑矩阵区53配置用以供相应的数据线2走线，以节省芯片的数据线而缩减芯片尺寸，同时可减少侧边框宽度，进而提升屏占比，使得开口率可大幅度提升，以提高光透过率，达到高亮度目的。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
