Description

一种阵列基板的制造方法及触摸屏 技术领域
本发明属于触控显示技术领域,具体地讲,涉及一种阵列基板的制造方法及触摸屏。
背景技术
触摸屏是允许用户使用手指或者物体通过选择显示在图像显示器等的屏幕上的指令内容来输入用户的指令的输入设备。用户的手或者物体在接触位置处直接与触摸屏相接触。由于这种触摸屏可以代替连接到图像显示器的诸如键盘或鼠标之类的独立输入设备,所以其应用领域已经日益扩大。目前,触摸屏已广泛应用于诸如智能移动电话、平板电脑(Pad)等电子设备中。
现有的触摸屏包括盖板、触控面板及显示面板(诸如,液晶显示面板)。按照触控面板设置位置的不同,可将触摸屏分为一体化触摸屏(OGS)、内置式(In-Cell)触摸屏及外挂式(On-Cell)触摸屏。与OGS触摸屏和On-Cell触摸屏不同,In-Cell触摸屏可在阵列基板上实现,即触控面板设置在的液晶显示面板的阵列基板上,其结构和制程相对简单,可靠性更高,使液晶显示面板整体更加轻薄。
图1是现有技术的一种能够实现In-Cell触摸屏的阵列基板的结构示意图。参照图1,现有技术的阵列基板包括:基板11;形成在基板11上的栅电极12及栅极线(未示出);形成在基板11上并覆盖栅电极12及栅极线的栅极绝缘层13;形成在栅极绝缘层13上的有源层14;形成在有源层14上的源电极15a和漏电极15b;形成在源电极15a和漏电极15b上的第一绝缘层16;形成在第一绝缘层16中的过孔16a,其中,该过孔16a使源电极15a暴露;形成在第一绝缘层16及过孔16a中的源电极15a上的公共电极层17;形成在第一绝缘层16上的第二绝缘层18,其中,第二绝缘层18覆盖第一绝缘层16上的公共电极层17;形成在第二绝缘层18中的穿孔18a;形成在第二绝缘层18上的金属电极19,其中,该金属电极19填充穿孔18a,并与公共电极层17接触;形成 在第二绝缘层18及过孔16a中的公共电极层17上的第三绝缘层20;形成在第三绝缘层20及过孔16a中的公共电极层17上像素电极21。
第一绝缘层16还起到平坦化的作用。公共电极层17同时也作为触摸感测电极;金属电极19作为触摸传导电极。然而,在图1所示的阵列基板的现有制造方法中,公共电极层17和第二绝缘层18各需要通过一道光刻(Photo Engraving Process)制程来完成,导致生产时间较长,从而造成生产效率较低,并且增加生产成本。
