Description
技术领域
本发明涉及显示技术领域,尤其涉及一种阵列基板及其制备方法与显示装置。
背景技术
随着TFT(Thin Film Transistor,薄膜晶体管)液晶显示技术的不断发展,具备功耗低、分辨率高、反应速度快以及开口率高等特点的基于LTPS(LowTemperature Poly-silicon,低温多晶硅)技术的TFT显示装置逐渐成为主流,已被广泛应用于各种电子设备,如液晶电视、智能手机、平板电脑以及数码相机等数字电子设备中。
但是,在基于LTPS技术的TFT显示装置等高分辨率产品中,随着产品分辨率以及开口率的越来越高,会导致LTPS TFT显示装置的阵列基板的像素间距(pixel pitch)越来越小,进而导致阵列基板的存储电容越来越小。由于对于LTPS TFT阵列基板来说,在同样大小漏电流情况下,存储电容越小会导致像素电压的保持率越低,进而会导致闪烁(Flicker)等不良现象的产生,极大地降低了阵列基板或TFT显示装置等高分辨率产品的品质,因此,如何在不影响阵列基板开口率的同时提高其存储电容,已成为业界亟需解决的问题。
发明内容
本发明实施例提供了一种阵列基板及其制备方法与显示装置,用以解决现有技术中存在的阵列基板的存储电容较小所导致的阵列基板或显示装置品质较低的问题。
本发明实施例提供了一种阵列基板,所述阵列基板包括衬底基板、依次形成在所述衬底基板上的缓冲层、半导体层、栅极绝缘层、栅金属层、层间介电层、源漏金属层以及像素电极层,还包括:
形成在所述衬底基板与所述缓冲层之间的公共电极层。
在本发明所述实施例中,可在形成缓冲层之前,在衬底基板上形成公共电极层,使得公共电极层不仅可与像素电极层形成存储电容,还可与半导体层形成存储电容,从而起到了增大阵列基板的存储电容、提高阵列基板的像素电压保持率以及降低显示装置的闪烁等不良现象的效果,提高了阵列基板及显示装置的品质。
另外,与现有技术相比,由于所述像素电极层可直接形成在所述源漏金属层上,因而还可省去后续保护层及钝化层等工艺制备流程,从而还可达到简化阵列基板的膜层结构以及制作工艺的效果。
进一步地,所述公共电极层在所述衬底基板上的水平投影区域分别与所述像素电极层在所述衬底基板上的水平投影区域以及所述半导体层在所述衬底基板上的水平投影区域存在重叠。
进一步地,所述半导体层为多晶硅层。
进一步地,所述源漏金属层包括源极、漏极和数据线的图案,所述层间介电层以及栅极绝缘层内形成有分别用于将所述源极、漏极与所述半导体层电连接的源极过孔以及漏极过孔。
进一步地,所述公共电极层由透明导电材料制备而成。
其中,所述透明导电材料为ITO(氧化锡铟)。
进一步地,本发明实施例还提供了一种显示装置,所述显示装置包括本发明实施例中所述的阵列基板。
进一步地,本发明实施例还提供了一种阵列基板制备方法,所述方法包括:
在衬底基板上形成公共电极层;
在所述公共电极层上形成缓冲层、半导体层、栅极绝缘层、栅金属层、层间介电层、源漏金属层以及像素电极层。
在本发明所述实施例中,可在形成缓冲层之前,在衬底基板上形成公共电极层,使得公共电极层不仅可与像素电极层形成存储电容,还可与半导体层形成存储电容,从而起到了增大阵列基板的存储电容、提高阵列基板的像素电压保持率以及降低显示装置的闪烁等不良现象的效果,提高了阵列基板及显示装置的品质。
另外,与现有技术相比,由于所述像素电极层可直接形成在所述源漏金属层上,因而还可省去后续保护层及钝化层等工艺制备流程,从而还可达到简化阵列基板的膜层结构以及制作工艺的效果。
进一步地,所述公共电极层在所述衬底基板上的水平投影区域分别与所述像素电极层在所述衬底基板上的水平投影区域以及所述半导体层在所述衬底基板上的水平投影区域存在重叠。
进一步地,所述半导体层为多晶硅层。
进一步地,所述源漏金属层包括源极、漏极和数据线的图案;在形成所述层间介电层之后,且在形成所述源漏金属层之前,所述方法还包括:
在所述层间介电层以及栅极绝缘层内形成分别用于将所述源极、漏极与所述半导体层电连接的源极过孔以及漏极过孔。
本发明有益效果如下:
本发明实施例提供了一种阵列基板及其制备方法与显示装置,所述阵列基板包括衬底基板、依次形成在所述衬底基板上的缓冲层、半导体层、栅极绝缘层、栅金属层、层间介电层、源漏金属层以及像素电极层,还包括:形成在所述衬底基板与所述缓冲层之间的公共电极层。在本发明所述实施例中,由于可在形成缓冲层之前,在衬底基板上形成公共电极层,使得公共电极层不仅可与像素电极层形成存储电容,还可与半导体层形成存储电容,起到了增大阵列基板的存储电容、提高阵列基板的像素电压保持率以及降低显示装置的闪烁等不良现象的效果,提高了阵列基板及显示装置的品质;另外,与现有技术相比,由于还可省去后续保护层及钝化层等工艺流程,从而还可达到简化阵列基板的膜层结构以及制作工艺的效果。

进一步地,所述源漏金属层17通常可包括源极、漏极和数据线的图案,本发明实施例对此不作赘述;相应地,所述层间介电层16以及栅极绝缘层14内还可形成有分别用于将所述源漏金属层17中的源极、漏极与所述半导体层13电连接的源极过孔以及漏极过孔(可分别标号为161或162),本发明实施例对此不作赘述。
在本发明所述实施例中,可在形成缓冲层12之前,在衬底基板11上形成公共电极层19,使得公共电极层19不仅可与像素电极层18形成存储电容,还可与半导体层13形成存储电容,起到了增大阵列基板的存储电容、提高阵列基板的像素电压保持率以及降低显示装置的闪烁等不良现象的效果,提高了阵列基板及显示装置的品质。
另外,与现有技术相比,由于所述像素电极层18与所述源漏金属层17之间不再设置有保护层、公共电极层以及钝化层等膜层结构,因此,还可省去后续保护层及钝化层等工艺制备流程,从而还可达到简化阵列基板的膜层结构以及制作工艺的效果。
进一步地,本发明实施例一还提供了一种阵列基板制备方法,具体地,下面将结合图2(a)~图2(i)对本发明实施例一中所述阵列基板制备方法进行简要说明,所述阵列基板制备方法可以包括以下步骤:

需要说明的是,所述公共电极层19的图案还可以全部覆盖所述衬底基板11,这样可以减少一次构图工艺,但会增加一些不必要的寄生电容,因此,优选地,所述公共电极层19的图案部分覆盖所述衬底基板,并且,其在所述衬底基板11上的水平投影区域分别与像素电极层18在所述衬底基板11上的水平投影区域以及半导体层13在所述衬底基板11上的水平投影区域存在重叠。

步骤104:在所述半导体层13上形成栅极绝缘层14,具体可如图2(d)所示。

进一步地,所述金属层可以为铝层、钨层、铬层或其他金属及金属化合物导电层等,本发明实施例对此不作任何限定。
步骤106:在所述栅金属层15上形成层间介电层16,具体可如图2(f)所示。
具体地,可采用CVD等方法在所述栅金属层15上沉积所述层间介电层16,以起到保护所述栅金属层15、并隔离所述栅金属层15和后续源漏金属层17的目的;其中,所述层间介电层16可由氧化硅、氮化硅等材料制备而成,本发明实施例对此不作任何限定。
步骤107:在所述层间介电层16及所述栅极绝缘层14之内形成贯通至所述半导体层13的源极过孔与漏极过孔(其中,所述源极过孔与漏极过孔可分别标号为161或162),具体可如图2(g)所示。
具体地,可采用一次或多次构图工艺在所述层间介电层16及所述栅极绝缘层14之内形成可直达所述半导体层13的源极过孔、漏极过孔,本发明实施例对此不作任何限定。

其中,所述导电材料可以为铝、钨、铬或其他金属及金属化合物等,本发明实施例对此不作任何限定。
需要说明的是,由于所述源漏金属层17通常可包括源极、漏极和数据线的图案,因此,与现有技术类似,在本步骤108中,在形成源极171、漏极172的同时,还可以同时形成数据线(Data),本发明实施例对此不作赘述。
步骤109:在所述源漏金属层17上形成像素电极层18,具体可如图2(i)所示。
具体地,可采用CVD等方法在所述源漏金属层17上沉积一透明导电材料层,并通过包括光刻胶涂敷、曝光、显影、刻蚀、光刻胶剥离等工艺的构图工艺来得到具备设定图案的像素电极层18。
