技术领域
本发明涉及液晶显示技术领域,具体而言涉及一种阵列基板、液晶显示面板及液晶显示装置。
背景技术
LCD(LiquidCrystalDisplay,液晶显示器)产生闪烁(Flicker)现象的原因有多种,最主要的原因是TFT(ThinFilmTransistor,薄膜晶体管)漏电的差异,即TFT在施加负性灰阶电压时的漏电大于施加正性灰阶电压时的漏电,导致阵列基板的存储电容在正负性灰阶电压时的电容量存在差值。随着LCD广泛应用于各个显示领域,并且为了降低功耗,LCD往往被施加较低的source(源极)驱动电压,导致相邻灰阶的灰阶电压之差变小,更容易加剧闪烁现象的发生,影响显示效果。
发明内容
有鉴于此,本发明提供一种阵列基板、液晶显示面板及液晶显示装置,能够改善闪烁现象的发生,确保显示效果。

具体实施方式
图1是本发明一实施例的液晶显示面板的结构剖视图。如图1所示,本实施例的液晶显示面板10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)11和阵列基板(ThinFilmTransistorSubstrate,简称TFT基板,又称薄膜晶体管基板或Array基板)12以及填充于两基板之间的液晶(液晶分子)13,该液晶13位于阵列基板12和彩膜基板11叠加形成的液晶盒内。
结合图2所示液晶显示面板10的像素结构示意图,阵列基板12包括沿列方向设置的数多条据线D、沿行方向设置的多条扫描线G以及由扫描线G和数据线D定义的多个像素区域P。其中,每一像素区域P连接对应的一条数据线D和一条扫描线G,各条扫描线G连接于栅极驱动器21以对各像素区域P提供扫描电压,各条数据线D连接于源极驱动器22以对各像素区域P提供灰阶电压。进一步结合图3所示的像素结构的等效电路图,阵列基板12包括薄膜晶体管T、存储电容Cst以及液晶电容Clc,液晶电容Clc由位于像素区域P的像素电极、液晶显示面板10的公共电极以及位于两者之间的液晶13形成。
根据液晶显示面板10的显示原理,通过为扫描线G输入扫描电压,位于同一行的薄膜晶体管T被同时打开,且在一定时间后下一行的薄膜晶体管T被同时打开,依次类推。由于每一行薄膜晶体管T打开的时间比较短,液晶电容Clc充电控制液晶13偏转的时间较短,很难达到液晶13的响应时间,存储电容Cst便可以用于在薄膜晶体管T关闭后维持像素区域P的电压,从而为液晶13响应提供时间。
本发明实施例的存储电容Cst为MIS(MetalInsulatorSemiconductor,金属-绝缘体-半导体)存储电容,如图4所示,该MIS存储电容Cst由金属层41和多晶硅(polycrystallinesilicon,P-Si)半导体层42通过夹持于两者之间的绝缘层43绝缘重叠形成。其中,对应位于MIS存储电容Cst区域的多晶硅半导体层42为重掺杂处理后的多晶硅层,优选在多晶硅层中重掺杂Be(铍)。
当金属层41一侧接收负性灰阶电压时,多晶硅半导体层42中的P-Si会聚集形成空穴421,当金属层41接收的灰阶电压由负性变为正性时,空穴421所在区域会形成耗尽层422,即在P-Si的上层会形成耗尽层422,该耗尽层422能够降低MIS存储电容Cst的电容量。也就是说,本实施例的MIS存储电容Cst相当于一个可变电容器,进一步结合图5所示的C-V(电容量-灰阶电压)曲线,当灰阶电压为负性时,MIS存储电容Cst的电容量为C1,当灰阶电压为正性时,MIS存储电容Cst的电容量为C2=C1*C0/(C1+C0),其中C0为耗尽层422与金属层41之间的电容量,可知C1>C2,即MIS存储电容Cst在接收负性灰阶电压时的电容量大于接收正性灰阶电压时的电容量。由于灰阶电压为负性时薄膜晶体管T的漏电较大,本发明实施例增加MIS存储电容Cst的电容量,则会降低薄膜晶体管T的漏电,从而改善TFT漏电的影响,即降低MIS存储电容Cst在接收正负性灰阶电压时的电容量差值,改善闪烁现象的发生,确保液晶显示面板10的显示效果。
在不同的像素结构设计中,MIS存储电容Cst的金属层41以及绝缘层43具体为液晶显示面板10的不同结构。下面结合附图6~13,对本发明实施例的技术方案进行清楚、完整地描述。
图6是本发明第一实施例的像素区域P的结构示意图,图7是图6所示像素区域P沿A-A线的结构剖视图。结合图6和图7所示,阵列基板12包括衬底基材121以及依次形成于衬底基材121上的十一层结构:遮光金属层M0、缓冲层122、多晶硅半导体层123、绝缘层(GateInsulationLayer,GI,又称栅极绝缘层)124、第一金属层Ml、介质隔离层(Interlayerdielectricisolation,ILD,又称层间介质隔离)125、第二金属层M2、平坦钝化层126、公共电极127、PV(Passivation,钝化)层128以及像素电极129。其中,多晶硅半导体层123、第一区域Zl的第一金属层Ml、第三区域Z3和第四区域Z4的第二金属层M2以及相互之间所夹持的绝缘层124、介质隔离层125形成阵列基板12的薄膜晶体管T。
在本实施例中,第一金属层Ml包括间隔设置的第一区域Zl和第二区域Z2,第一区域Zl的第一金属层Ml为薄膜晶体管T的栅极;第二金属层M2包括间隔设置的第三区域Z3和第四区域Z4,第三区域Z3和第四区域Z4的第二金属层M2分别为薄膜晶体管T的源极和漏极;遮光金属层M0包括间隔设置的第五区域Z5和第六区域Z6,第五区域Z5位于第一区域Z1的下方。鉴于薄膜晶体管T的栅极位于多晶硅半导体层123的上方,本实施例的像素区域P可视为顶栅型像素设计。
