目前液晶显示装置以晶体管(TFT)液晶显示装置为主,然而,随着晶体管液晶显示装置分辨率(PPI)的不断提升,需要在显示区(AA)设置更多的晶体管,晶体管的位置排布已经成为影响像素开口率的关键因素。由于液晶显示装置的背光会影响到晶体管本身的器件特性,所以需要在晶体管下方增加遮光(LS)层,而且为了更好阻挡光照,遮光层的面积要大于晶体管本身,这导致像素开口率进一步降低。
为了改善相关技术中存在的上述技术问题,本公开实施例提供了一种显示基板,如图1和图2所示,包括:
衬底基板101;
晶体管102,位于衬底基板101之上,晶体管102包括有源层21,有源层21的材料为多晶硅、金属氧化物中的一种或多种,可选地,金属氧化物可以为氧化铟镓锌(IGZO)、非晶态或多晶态的氧化锌(ZnO)、氧化铟锌(IZO)、氧化锌锡(ZTO)、氧化锡锌(IZTO)、氧化镓锌锡(IGZTO)、氧化铟镓(IGO)中的任意一种或多种;
数据线103,位于有源层21与衬底基板101之间,数据线103与有源层21相连,有源层21在衬底基板101上的正投影位于数据线103在衬底基板101上的正投影内。
在本公开实施例提供的上述显示基板中,通过将有源层21设置在数据线103的上方,并保证有源层21在衬底基板101上的正投影位于数据线103在衬底基板101上的正投影内,使得数据线103可有效遮挡背光,相当于数据线103兼具遮光层的作用,从而避免了单独增设遮光层,利于提高像素开口率。
可选地,数据线103的材料可以包括金属材料,例如由钼、铝、钛、铜、合金等形成的单层或多层结构,示例性地,数据线103为钛金属层/铝金属层/钛金属层构成的叠层结构。
在一些实施例中,在本公开实施例提供的上述显示基板中,如图1和图2所示,还可以包括在晶体管102所在层远离衬底基板101的一侧依次设置的转接电极104、平坦层105和第一电极106,平坦层105包括第一过孔V 1,第一电极106通过第一过孔V 1与转接电极104相连,转接电极104与有源层21相连,有源层21的材料包括多晶硅(P-Si),转接电极104的材料包括金属材料。金属材料不会改变多晶硅的性质,因此可以保证有源层21的性能稳定。
在一些实施例中,在本公开实施例提供的上述显示基板中,平坦层105可以采用有机绝缘材料制作,受有机绝缘材料自身属性的影响,第一过孔V 1的孔径要大于数据线103的线宽,因此部分第一过孔V 1超出数据线103而不能被数据线103遮挡,这会导致在未被数据线103遮挡的第一过孔V 1出现漏光现象。
为了解决第一过孔V 1的漏光问题,如图3所示,本公开的数据线103在对应第一过孔V 1的位置设置了加宽部31,加宽部31在衬底基板101上的正投影覆盖第一过孔V 1在衬底基板101上的正投影,即加宽部31在衬底基板101上的正投影面积大于等于第一过孔V 1在衬底基板101上的正投影面积,换言之,第一过孔V 1在衬底基板101上的正投影位于加宽部31在衬底基板101上的正投影内,或者第一过孔V 1在衬底基板101上的正投影与加宽部31在衬底基板101上的正投影重合。
可选地,如图3所示,第一过孔V 1在衬底基板101上的正投影边界与加 宽部31在衬底基板101上的正投影边界之间的距离d 1大于等于0且小于等于3μm,例如0μm、0.5μm、1μm、1.5μm、2μm、2.5μm、3μm等。加宽部31在垂直于数据线103的方向上,单侧超出数据线103的距离d 2大于等于0.5μm且小于等于1.5μm,例如0.5μm、1μm、1.5μm等。可选地,在有源层21远离数据线103所在层的一侧,还可以设置有栅线107,在数据线103延伸方向上,加宽部31在衬底基板101上的正投影与栅线107在衬底基板101上的正投影之间的距离d 3大于等于0.3μm且小于等于1μm,例如0.3μm、0.4μm、0.5μm、0.6μm、0.7μm、0.8μm、0.9μm、1μm等。在高分辨率产品中,各线宽都较现有技术缩小,且精细化,分辨率越高产品,对各线宽、及线间距的尺寸把控越严格,在本公开中根据上述参数设置加宽部31,即可解决第一过孔V 1的漏光问题,同时又不影响开口率。
在一些实施例中,还可以采用包括金属材料的转接电极104遮挡背光,以解决第一过孔V 1的漏光问题,基于此,本公开中还可以使得转接电极104在衬底基板101上的正投影覆盖第一过孔V 1在衬底基板101上的正投影,即转接电极104在衬底基板101上的正投影面积大于等于第一过孔V 1在衬底基板101上的正投影面积,换言之,第一过孔V 1在衬底基板101上的正投影位于转接电极104在衬底基板101上的正投影内,或者第一过孔V 1在衬底基板101上的正投影与转接电极104在衬底基板101上的正投影重合。
在一些实施例中,在本公开实施提供的上述显示基板中,如图1至图3所示,晶体管102包括位于有源层21远离数据线103所在层一侧的栅极22,由于可通过数据线103和/或转接电极104解决第一过孔V 1的漏光问题,因此,无需再采用栅极22解决第一过孔V 1的漏光问题,基于此,栅极22在衬底基板101上的正投影与第一过孔V 1在衬底基板101上的正投影可以互不交叠。当然,在一些实施例中,栅极22在衬底基板101上的正投影也可以与第一过孔V 1在衬底基板101上的正投影相互交叠,以通过栅极22在一定程度上改善第一过孔V 1的漏光不良。
可选地,为避免转接电极104与栅极22之间形成寄生电容而相互干扰, 如图1至图3所示,栅极22在衬底基板101上的正投影可以与转接电极104在衬底基板101上的正投影互不交叠。在一些实施例中,栅极22可以与栅线107复用,数据线103可以与晶体管102的源极复用,转接电极104可以与晶体管的漏极复用,或者,数据线103与晶体管102的漏极复用,转接电极104与晶体管的源极复用。
相关技术中有源层21为与数据线103互不交叠且面积较大的U型结构,影响像素开口率。由图1和图3可见,本公开中有源层21为位于数据线103正投影内的条状结构,可有效提高像素开口率。可选地,为了增强栅控能力,本公开还可以将晶体管102设置为双栅型晶体管,具体地,如图4至图6所示,栅极22包括正投影与条状结构的有源层21交叠的第一栅极221和第二栅极222,其中,第一栅极221与栅线107复用,第二栅极222与栅线107交叉且一体设置,即第一栅极221和第二栅极222形成分叉双栅。
在一些实施例中,在本公开实施例提供的上述显示基板中,如图4所示,第二栅极222与栅线107的夹角为锐角。或者,如图5和图6所示,第二栅极222包括第一子栅极L 1和第二子栅极L 2,第一子栅极L 1连接第二子栅极L 2与栅线107,且第一子栅极L 1与栅线107的夹角大于0°且小于等于90°,第二子栅极L 2与栅线107平行设置。当然,在具体实施时,第二栅极222还可以具有其他结构,在此不做具体限定。
在一些实施例中,在本公开实施例提供的上述显示基板中,第一子栅极L 1的线宽可以等于第二子栅极L 2的线宽,为了进一步提高像素开口率,第一子栅极L 1的线宽可以小于第二子栅极L 2的线宽。示例性地,第一子栅极L 1的线宽大于等于0.5μm且小于等于3μm(例如0.5μm、1μm、1.5μm、2μm、2.5μm、3μm等),第二子栅极L 2的线宽大于等于1μm且小于等于3μm(例如1μm、1.5μm、2μm、2.5μm、3μm等)。
在一些实施例中,在本公开实施例提供的上述显示基板中,如图7和图8所示,还可以设置第一过孔V 1的至少部分在衬底基板101上的正投影位于栅线107在衬底基板101上的正投影内,可选地,第一过孔V 1在衬底基板101 上的正投影位于栅线107在衬底基板101上的正投影内,以通过栅线107遮挡背光,避免第一过孔V 1处漏光。在此情况下,如图7和图8所示,可以设置转接电极104包括层叠设置的第一转接电极41和第二转接电极42,其中,第一转接电极41的材料为金属(例如钼、铝、钛、铜、合金等),第二转接电极42的材料为透明导电氧化物(例如氧化铟锡、氧化铟锌等),第一转接电极41在衬底基板101上的正投影与栅线107在衬底基板101上的正投影互不交叠,第二转接电极42在衬底基板101上的正投影与栅线107在衬底基板101上的正投影部分交叠,以通过第二转接电极42支撑正投影与栅线107交叠的第一过孔V 1。且相较于采用金属材质的第一转接电极41支撑第一过孔V 1的方案,透明导电氧化物材质的第二转接电极42支撑第一过孔V 1的方案可以有效增大像素开口率。
在一些实施例中,在本公开实施例提供的上述显示基板中,如图1至图8所示,还可以包括位于转接电极104所在层与栅极22所在层之间的层间介电层108、以及位于栅极22所在层与有源层21之间的栅绝缘层109,层间介电层108和栅绝缘层109包括相互贯通的第二过孔V 2,转接电极104通过第二过孔V 2与有源层21相连。可选地,层间介电层108和栅绝缘层109的材料可以均为氧化硅、氮化硅、氮氧化硅等无机绝缘材料,使得可通过一次构图工艺形成贯穿层间介电层108和栅绝缘层109的第二过孔V 2
在一些实施例中,在本公开实施例提供的上述显示基板中,如图2和图8所示,还可以包括位于第一电极106所在层远离平坦层105一侧的第二电极110,第二电极110在衬底基板101上的正投影与第一电极106在衬底基板101上的正投影至少部分交叠。相关技术中的数据线103位于栅极22与转接电极104所在层之间,本公开中数据线103位于有源层21与衬底基板101之间,因此,相较于相关技术,本公开中数据线103所在层与第二电极110所在层之间的距离较大,由此可有效减少数据线103与第二电极110的寄生电容,从而显著降低功耗。
可选地,本公开适用于液晶显示产品,此时,第一电极106为像素电极, 第二电极110为公共电极,公共电极可为狭缝状电极,并且第一电极106与第二电极110之间还可以设置有无机绝缘层111。或者,本公开适用于有机发光显示产品,此时,第一电极106可以为阳极,第二电极110为阴极,且第一电极106和第二电极110之间设置有发光功能层,使得第一电极106、第二电极110和发光功能层共同构成发光器件(例如有机发光器件OLED),其中,发光功能层包括但不限于空穴注入层、空穴传输层、电子阻挡层、发光材料层、空穴阻挡层、电子传输层和电子注入层。

第三步,在缓冲层112上形成非晶硅层,并对非晶硅层进行结晶化,使得非晶硅层转化为本征多晶硅层后,对本征多晶硅层进行图案化,形成通过第三过孔V 3与数据线103搭接的有源层21,并且有源层21在衬底基板101上的正投影落入数据线103在衬底基板101上的正投影内,如图11所示。可选地,还采用光刻胶(PR)遮挡多晶硅有源层21的沟道区,并对暴露出的多晶硅有源层21的源区和漏区进行n型掺杂,使得源区和漏区的本征多晶硅转变为导电的n型多晶硅,以提高有源层21与数据线103的连接效果。
第四步,在有源层21上依次形成栅绝缘层109和栅金属层,并对栅金属层进行图案化后,形成位于有源层21上方的栅极22,如图12所示。

第七步,在转接电极104所在层上形成平坦层105,该平坦层105具有与位于数据线103的加宽部31处的第一过孔V 1,如图15所示。
第八步,在平坦层105上形成透明导电层,并对透明导电层进行图案化后形成第一电极106,使得第一电极106通过第一过孔V 1与转接电极104相连,如图16所示。
