Description

阵列基板、触控显示面板和触控显示装置 技术领域
本发明的实施例涉及一种阵列基板、触控显示面板和触控显示装置。
背景技术
有源矩阵发光二极管显示器(Active Matrix Organic Light Emitting Diode，AMOLED)具有响应速度快、亮度高、低功耗、视角好、可实现柔性显示等特点而成为显示器技术发展的主流。具有触控功能的AMOLED显示器是基于功能丰富化的需求所产生的。比较常用的触控技术包括On-cell触控技术和内嵌式(In-cell)触控技术。在中小尺寸AMOLED显示器中常采用外敷式(On-cell)触控技术。而In-cell触控技术相比On-cell触控技术能够使显示器更轻薄，因此In-cell触控技术应于AMOLED显示器更被关注。
但是，In-cell触控技术应用于AMOLED显示器时，通常是将触控传感器制作在封装基板上，然后将封装基板与阵列基板贴合，触控传感器位于阵列基板与封装基板之间。但是，上述方式仅限于应用在玻盖封装工艺中，而无法在薄膜封装工艺中实现，其原因在于薄膜封装工艺是真空环境下在阵列基板上沉积多次薄膜，防止水氧侵蚀OLED器件的封装方式，此种封装方式在阵列基板上方不需要覆盖玻璃基板，即无封装基板，因此无法实现传感器作在封装基板上。可见，In-cell触控技术应用于AMOLED显示器具有较大的局限性。
发明内容
本发明至少一实施例提供了一种阵列基板，其包括衬底基板，所述衬底基板上具有相互交叉的数据线和栅线围设而成的多个像素单元；每一个所述像素单元包括一个底发射型的OLED显示器件和至少一个TFT，所述OLED显示器件包括透明的阳极；所述阵列基板还包括与所述数据线平行且同层设置的多条第一电极，与所述栅极平行且与所述阳极同层设置的多条第二电极；至少一条所述第一电极构成一条触控驱动线，至少一条所述第二电极构成一 条触控感应线。
本发明至少一实施例中，所述衬底基板的所述数据线所在层形成有多条所述第一电极，在所述阳极所在层形成有多条所述第二电极，由至少一条所述第一电极构成所述触控驱动线，由至少一条所述第二电极构成所述触控感应线。由此，可在所述衬底基板上实现触控传感器，可以应用于不同工艺所制备的AMOLED显示器中。
例如，所述第一电极在行方向上均匀排布，所述第二电极在列方向上均匀排布，所述第一电极和所述第二电极均设置在所述阵列基板的非发光区域。本发明实施例中，所述第一电极和所述第二电极分别在行方向和列方向上均匀排布。这使得所得到的触控检测点分布均匀，有利于提高触控检测的精确度。
例如，相邻的两条所述第一电极间隔至少一列所述像素单元；相邻的两条所述第二电极间隔至少一行所述像素单元。本发明实施例中，各所述第一电极之间的间隔可以灵活设置，各所述第二电极之间的间隔可以灵活设置，实现不同精度的触控检测。
