Description

液晶显示面板及液晶显示装置
技术领域
本发明涉及液晶显示技术领域,特别是涉及一种液晶显示面板及液晶显示装置。
背景技术
液晶显示器是目前使用最广泛的一种平板显示器,随着液晶显示器技术的发展进步,人们对液晶显示器的显示品质、外观设计、低成本和高穿透率等提出了更高的要求。
目前普遍采用的液晶显示器通常包括两种,一种是由上下衬底和中间液晶层组成,衬底由玻璃和电极等组成,如TN(TwistNematic;扭转向列型)模式,VA(VerticalAlignment;垂直对齐)模式,以及为了解决视角过窄开发的MVA(MultidomainVerticalAlignment;多区域垂直排列)模式。另一种是电极只位于衬底的一侧,形成横向电场模式的显示器,如IPS(In-planeswitching;平面方向转换)模式、FFS(FringeFieldSwitching;边缘场开关)模式等。
其中,FFS模式是IPS模式衍生出来的广视角技术,FFS的结构是在电极间距下方设置一般电极,施加电压就会产生边界电场使液晶在电极上旋转,藉由边界电场使几乎均质排列的液晶分子在电极表层内部旋转,达到高穿透性与大视角特性。请参看图1和图2,图1为现有技术中的液晶显示面板的像素结构图,图2是图1中的像素结构沿A-A′切线的剖面图,如图1和图2所示,现在技术的FFS液晶显示面板1中的像素电极15与公共电极14完全重叠,位于像素电极15和公共电极14之间的钝化(Passivation;简称PV)层13很薄,使得像素电极15和公共电极14之间形成很大的存储电容,过大的存储电容将造成液晶显示面板充电不足,电阻电容负载过重,像素充电时间过长。
发明内容
有鉴于此,本发明提供一种液晶显示面板及显示装置,能够减小像素的存储电容,提升像素的充电能力,并且降低液晶显示面板的驱动电压,从而降低液晶显示面板的功耗。
本发明的一方面提供一种液晶显示面板,包括:公共电极、第一像素电极及第二像素电极,第一像素电极及第二像素电极间隔排列,且第一像素电极与公共电极及第二像素电极与公共电极部分重叠,公共电极与第一像素电极的重叠部分及公共电极与第二像素电极的重叠部分为镂空结构。
其中,液晶显示面板还包括钝化层,钝化层设置于公共电极与第一像素电极及第二像素电极之间。
其中,钝化层对应于公共电极与第一像素电极及公共电极与第二像素电极的非重叠区域设置有凹槽。
其中,镂空结构的面积小于第一像素电极的面积或第二像素电极的面积。
其中,液晶显示面板还包括基板、栅绝缘层、信号线及PFA有机膜层,其中,
栅绝缘层设置于基板上方;
信号线间隔设置于栅绝缘层上方;
PFA有机膜层覆盖信号线并延伸到栅绝缘层上;
公共电极设置于PFA有机膜层上方;
钝化层覆盖公共电极;
第一像素电极及第二像素电极间隔设置于钝化层上方。
本发明的另一方面提供一种液晶显示装置,该液晶显示装置包括液晶显示面板,液晶显示面板包括公共电极、第一像素电极及第二像素电极,其中,第一像素电极及第二像素电极间隔排列,且第一像素电极与公共电极及第二像素电极与公共电极部分重叠,公共电极与第一像素电极的重叠部分及公共电极与第二像素电极的重叠部分为镂空结构。
其中,液晶显示面板还包括钝化层,钝化层设置于公共电极与第一像素电极及第二像素电极之间。
其中,钝化层对应于公共电极与第一像素电极及公共电极与第二像素电极的非重叠区域设置有凹槽。
其中,镂空结构的面积小于第一像素电极的面积或第二像素电极的面积。
其中,液晶显示面板还包括基板、栅绝缘层、信号线及PFA有机膜层,其中,
栅绝缘层设置于基板上方;
信号线间隔设置于栅绝缘层上方;
PFA有机膜层覆盖信号线并延伸到栅绝缘层上;
公共电极设置于PFA有机膜层上方;
钝化层覆盖公共电极;
第一像素电极及第二像素电极间隔设置于钝化层上方。
通过上述方案,本发明的有益效果是:区别于现有技术,本发明的液晶显示面板及液晶显示装置,通过将公共电极与像素电极的重叠部分设置为镂空结构以实现减小液晶显示面板的像素电极与公共电极之间的交叠面积的目的,进而减小像素电极与公共电极之间的存储电容的电容值,从而可以弥补现有技术因存储电容电容值过大造成的充电不足,进而可进一步减小像素的充电时间,降低驱动电压,降低液晶显示面板的功耗。

液晶显示面板包括相对间隔设置的彩膜基板(ColorFilterSubstrate,简称CF基板,又称彩色滤光片基板)和阵列基板(ThinFilmTransistorSubstrate,简称TFT基板,又称薄膜晶体管基板或Array基板)以及填充于两基板之间的液晶(液晶分子),液晶位于阵列基板和彩膜基板叠加形成的液晶盒内。其中,TFT阵列基板通常包括玻璃基板、公共电极、栅极、栅绝缘层、非晶硅层、有源半导体层、源电极、漏电极、钝化层及像素电极。此外,TFT阵列基板还可以在栅绝缘层上方覆盖设置PFA有机膜层,PFA有机膜层用于减小液晶显示面板的寄生电容,其中,PFA有机膜为一种聚合物膜,可以采用丙烯酸树脂、环氧树脂和聚乙烯醇等化合物制成,PFA有机膜层同样具有绝缘作用。
请参见图3,图3是本发明一实施例的液晶显示面板的像素结构示意图。如图3所示,本实施例所揭示液晶显示面板2包括基板(图3未示)、在基板上沿列方向设置的多条信号线D及在基板上沿行方向设置的多条扫描线G,多条扫描线G和多条信号线D垂直交替设置。其中,多条扫描线G和多条信号线D交替形成多个像素单元,每个像素单元包括多个像素电极25以及公共电极24,公共电极24与像素电极25间隔设置,以形成存储电容。液晶显示面板2进一步包括薄膜晶体管,薄膜晶体管的栅极(图未示)设置在扫描线G上,薄膜晶体管的源极26与信号线D连接,薄膜晶体管的漏极27与像素电极25连接。当扫描线G提供扫描信号时,薄膜晶体管导通,像素电极25通过薄膜晶体管与信号线D连接,以获取信号线D所提供的数据信号。
请进一步参见图4a至图4f,图4a至图4f是图3所示的液晶显示面板2的像素结构的形成示意图。本实施例的像素结构的形成过程具体包括:
在基板(图未示)上设置扫描线G,如图4a所示。并且进一步在扫描线G上设置薄膜晶体管的栅极及在栅极上设置栅绝缘层,栅绝缘层覆盖栅极并延伸到基板上(图4a中未标示栅极及栅绝缘层的结构)。
进一步在薄膜晶体管的栅极上设置非晶硅层21(AmorphousSi),非晶硅层21覆盖设置于薄膜晶体管的栅极上方,如图4b所示。
在非晶硅层21上设置信号线D以及薄膜晶体管的源极26和漏极27,其中信号线D与扫描线G垂直交替设置,薄膜晶体管的源极26和漏极27设置在非晶硅的上方,其中薄膜晶体管的源极26与信号线D连接,如图4c所示。
在信号线D以及薄膜晶体管的源极26和漏极27上设置PFA有机膜层22,如图4d所示。其中,PFA有机膜层22覆盖信号线D、源极26、漏极27及栅绝缘层,并且,PFA有机膜层22上还设置有通孔(图未示)。
进一步在PFA有机膜层22上设置公共电极24,其中,公共电极24具有镂空28结构,镂空28区域间隔设置于公共电极24上,如图4e所示。
进一步在公共电极24上方设置钝化层23,如图4f所示,其中,钝化层23覆盖公共电极24并延伸到PFA有机膜层22上,并且钝化层23上方也设置有通孔(图未示)。
进一步在钝化层23上方设置多个像素电极25,设置像素电极25后的图如图3所示。
请进一步参看图5,图5是图3所示的像素结构沿B-B′切线的第一实施例的剖面图。如图5所示,本实施例的像素结构沿B-B′切线切开可以看到,本实施例的液晶显示面板的像素结构包括基板100、栅绝缘层101、信号线D、PFA有机膜层22、公共电极24、钝化层23及像素电极25。其中,栅绝缘层101位于基板100上方,信号线D间隔设置于栅绝缘层101上方,PFA有机膜层22覆盖信号线D并延伸到栅绝缘层101上,公共电极24设置于PFA有机膜层22上,且公共电极24具有间隔设置的镂空28结构,钝化层23覆盖公共电极24并延伸到PFA有机膜层22,像素电极25间隔设置于钝化层23上,并且,像素电极25与公共电极24部分重叠,公共电极24对应与像素电极25的重叠部分为镂空28结构,且镂空28结构的面积小于像素电极25的面积。
这里以第一像素电极251及第二像素电极252为例说明。液晶显示面板2包括公共电极24、第一像素电极251及第二像素电极252。其中,第一像素电极251及第二像素电极252间隔排列,并且,第一像素电极251与公共电极24及第二像素电极252与公共电极24均部分重叠,公共电极24对应于与第一像素电极251的重叠部分和公共电极24对应于与第二像素电极252的重叠部分均为镂空28结构,并且镂空28区域的面积小于第一像素电极25的面积或小于第二像素电极25的面积,即公共电极24的镂空28区域对应第一像素电极251的部分位置区域和对应第二像素电极252的部分位置区域。其中,第一像素电极251及第二像素电极252通过PFA有机膜层22及钝化层23上设置的通孔与漏电极27连接。
请参看图6,图6是图3所示的像素结构沿B-B′切线的第二实施例的剖面图。其中,本实施例与上述实施例的区别在于,钝化层23对应于公共电极24与像素电极25的非重叠区域形成有凹槽,这是通过对钝化层23进一步进行干刻工艺以使钝化层23形成具有凹槽的结构。即钝化层23对应于公共电极24与第一像素电极251及公共电极24与第二像素电极252的非重叠区域设置有凹槽。通过对钝化层23进行干刻工艺使得钝化层23对应于公共电极24与像素电极25的非重叠区域形成有凹槽结构,从而使得液晶显示面板可以提升显示面积的穿透率。
本发明还提供一种液晶显示装置,该液晶显示装置包括上述液晶显示面板2及为上述液晶显示面板提供光源的背光模组及其他元器件。
综上所述,区域别于现有技术,本发明的液晶显示面板及液晶显示装置,通过在阵列基板的公共电极上设置镂空结构,从而使得公共电极与像素电极之间的交叠面积减小,实现减小公共电极与像素电极之间的存储电容的目的,从而降低液晶显示面板的驱动电压,减小像素的充电时间,并且降低液晶显示面板的功耗。
以上所述仅为本发明的实施方式,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
