Description

液晶显示像素结构及液晶显示器件

技术领域

[0001]本发明涉及液晶显示领域,尤其是涉及一种可以提升像素开口率和穿透率的液晶显示像素结构及液晶显示器件。

背景技术

[0002] 薄膜场效应晶体管液晶显不器(Thin Film Transistor-Liquid CrystalDisplay,TFT-LCD)液晶面板设计中,为了获得更好的大视角特性,像素设计时往往会将像素的开口区分为若干个区域,以避免像素开口区只有一个区从侧面观看时会存在偏蓝或者偏黄的现象的问题。现在的液晶面板技术中,FFS(Fringe Field Switching,边缘场开关)/IPSdn-Plane Switching,平面转换)模式液晶面板由于大视角特性好、开口率/穿透率高等优点,已经被广泛采用。

[0003]参考图1,现有FFS模式液晶面板像素结构示意图;FFS模式液晶面板10显示区域内部,水平方向延伸的栅极信号线(Gate Line)Gl和竖直方向延伸的数据信号线(Data Line)Dl相互交错排列,以定义出多个像素区。每一像素区的开口区12(如图1中标号12所示虚框部分)内包括一像素电极Pl (pixel electrode),开口区12分为上、下两个显示域(IstDomain,2nd Domain),也即像素电极Pl具有两个显示域;数据信号线Dl配置于开口区12的边缘(如图1所示,Dl位于开口区12左侧),像素电极Pl的两个显示域(lst-2nd Domain)位于栅极信号线Gl的同一侧(如图1所示,lst_2nd Domain均位于Gl上方);TFT晶体管Tl作为开关控制像素电极Pl的信号写入。两个显示域(lst_2nd Domain)中像素电极Pl的延伸方向是不同的,如图两个显示域的液晶分子分别沿顺时针和逆时针方向转动,利用这个特性来改善FFS模式液晶面板的大视角特性。在两个显示域(lst_2nd Domain)的交界处14(如图1中标号14所示虚框部分),液晶分子转动的方向相反;在液晶面板正常工作时,该处朝不同方向转动的液晶分子会相互挤压,最后在开口区12内形成一条暗纹,造成像素的穿透率会有一定的损失,不利于开口率和穿透率的提升。

[0004] 参考图2,现有HVA模式液晶面板像素结构示意图;HVA(High VerticalAl ignment,高垂直配向)模式液晶面板20显示区域内部,水平方向延伸的栅极信号线GI和竖直方向延伸的数据信号线Dl以阵列的形式垂直相交,以定义出多个像素区。每一像素区的开口区22内包括一像素电极Pl;像素电极Pl整体呈一个“米”字形,像素电极Pl的主干为水平方向和竖直方向交叉,将整个像素电极Pl分为4个显示域(lst_4th Domain)(即开口区22分为四个显示域)。数据信号线Dl配置于开口区22的边缘(如图2所示,Dl位于开口区22左侧),像素电极Pl的四个显示域(lst_4th Domain)位于栅极信号线Gl的于同一侧(如图2所示,lst-4th Domain位于Gl上方);TFT晶体管Tl设置在公共电极COMl上以作为开关控制像素电极Pl的信号写入。在4个显示域(lst_4th Domain)内,液晶分子分别沿着45度,135度,225度和315度方向进行偏转,利用这个特性来改善HVA模式液晶面板的大视角特性。但和图1所示FFS模式液晶面板的工作原理相同,在四个显示域的交界处,即像素电极Pl的主干位置(如图2中标号24、26所示虚框部分),液晶分子分别向不同的方向偏转;在液晶面板正常工作时,该处朝不同方向转动的液晶分子会相互挤压,最后在开口区22内形成暗纹,造成像素的穿透率会有一定的损失,不利于开口率和穿透率的提升。

[0005]因此,亟需提供一种新的液晶显示像素结构,以提升液晶面板像素的开口率和穿透率,提尚液晶面板显不品质。

发明内容

[0006]本发明的目的在于,提供一种液晶显示像素结构及液晶显示器件,与现有的液晶显示像素结构相比,可以提升液晶面板像素的开口率和穿透率,提高液晶面板显示品质。

[0007]为实现上述目的,本发明提供了一种液晶显示像素结构,所述的液晶显示像素结构包括:一像素电极,位于像素开口区内,所述像素电极具有至少两个显示域,所述的至少两个显示域呈上下排列;一栅极信号线,位于所述的至少两个显示域的交界处,且所述的至少两个显示域交界处的边缘均与所述栅极信号线重叠;一数据信号线,所述数据信号线配置于所述像素开口区的边缘;一晶体管,所述像素电极通过所述晶体管受所述栅极信号线和所述数据信号线的控制。

[0008]为实现上述目的,本发明还提供了一种液晶显示器件,所述的液晶显示器件具有多条水平方向延伸的栅极信号线和多条竖直方向延伸的数据信号线以阵列的形式相交,以定义出多个像素区,每一像素区包括一如本发明所述的液晶显示像素结构。

[0009]为实现上述目的,本发明提供了一种液晶显示像素结构,所述的液晶显示像素结构包括:一像素电极,位于像素开口区内,所述像素电极具有至少四个显示域,所述像素电极的一第一显示域和一第二显示域呈左右排列,所述像素电极的一第三显示域和一第四显示域呈左右排列;一栅极信号线,所述第一显示域和所述第二显示域配置于所述栅极信号线的上方,且所述第一显示域和所述第二显示域的下边缘均与所述栅极信号线重叠,所述第三显示域和所述第四显示域配置于所述栅极信号线的下方,且所述第三显示域和所述第四显示域的上边缘均与所述栅极信号线重叠;一数据信号线,所述数据信号线配置于所述像素开口区的边缘;一晶体管,所述像素电极通过所述晶体管受所述栅极信号线和所述数据信号线的控制。

[0010]为实现上述目的,本发明还提供了一种液晶显示器件,所述的液晶显示器件具有多条水平方向延伸的栅极信号线和多条竖直方向延伸的数据信号线以阵列的形式垂直相交,以定义出多个像素区,每一像素区包括一如本发明所述的液晶显示像素结构。

[0011]本发明的优点在于,通过本发明提供的液晶显示像素结构及液晶显示器件,像素的开口区被栅极信号线所隔开,隔开后的显示域交界处的边缘(即像素开口区分界线)与栅极信号线重叠,由于栅极信号线本身是不透光结构,它与像素开口区分界线重叠后并不会影响开口率和穿透率;各显示域中液晶分子偏转无规律的部分均与栅极信号线重叠,借助栅极信号线本身是由不透光的金属材料制作所起到的遮光作用,避免了液晶面板正常工作时在像素开口区内形成暗纹,提高了像素的开口率和穿透率。且由于液晶分子转动异常的部分被不透光的栅极信号线所遮挡,也可以避免液晶面板受到按压时两显示域交界处可能出现的显示异常情况,进一步提升液晶面板显示品质。另外,相邻两像素区之间的区域可以是空白区域,也可以布置COM电极线,对开口率和设计布线的灵活性有明显的帮助。本发明提供的液晶显示像素结构及液晶显示器件可以适用于FFS/IPS模式液晶面板,以及HVA模式液晶面板。

具体实施方式

[0018]下面结合附图对本发明提供的液晶显示像素结构及液晶显示器件做详细说明。

[0019]参考图3、图4,其中图3为本发明一实施例所述的液晶显示器件的像素结构示意图,图4为图3所示实施例中A区域的放大示意图;本实施例中适用于FFS/IPS模式的液晶面板。所述的液晶显示器件30具有多条水平方向延伸的栅极信号线Gl和多条竖直方向延伸的数据信号线Dl以阵列的形式相交,以定义出多个像素区31,每一像素区31包括一液晶显示像素结构。所述的液晶显示像素结构包括:一像素电极Pl,一栅极信号线G1、一数据信号线Dl以及一晶体管Tl;其中,像素电极Pl具有至少两个显示域。

[0020] 像素电极Pl,位于像素开口区内,像素电极Pl具有两个显示域1st Domain,2ndDomain,以避免液晶面板在大视角观看时颜色偏黄和偏蓝的问题;两个显示域(lst-2ndDomain)呈上下排列。

[0021] 栅极信号线G1,位于两个显示域(lst_2nd Domain)的交界处,且交界处的边缘均与栅极信号线Gl重叠;也即,像素开口区被栅极信号线Gl所隔开,隔开后的显示域交界处的边缘(即像素开口区分界线)与栅极信号线Gl重叠。如图4所示,显示域1st Domain的下边缘41与栅极信号线Gl重叠,显示域2nd Domain的上边缘42与栅极信号线Gl重叠;也即,使两显示域中液晶分子偏转无规律的部分均与栅极信号线重叠,借助栅极信号线本身是由不透光的金属材料制作所起到的遮光作用,避免了液晶面板正常工作时在像素开口区内形成暗纹,提高了像素的开口率和穿透率。且由于液晶分子转动异常的部分被不透光的栅极信号线所遮挡,也可以避免液晶面板受到按压时两显示域交界处可能出现的显示异常情况,进一步提升液晶面板显示品质。

[0022]数据信号线Dl,配置于像素开口区的边缘(如图3所示,Dl位于像素开口区左侧)。本发明由于每一像素电极仅配置一条数据信号线,且数据信号线位于像素电极的两侧(本实施例数据信号线位于左侧)而非贯穿于像素电极的中间,避免了因数据信号线的增加而带来的寄生电容大幅增加、驱动IC的温度升高、信赖性会受到影响的问题。

[0023]像素电极Pl通过晶体管Tl受栅极信号线Gl和数据信号线Dl的控制。也即,一个像素区内部只有一个TFT,晶体管所占的面积更小,有效提升了液晶面板的穿透率。

[0024]在本实施例中,两个显示域(lst-2nd Domain)中像素电极Pl的延伸方向是不同的,在液晶面板点灯工作时两个显示域中的液晶分子分别沿顺时针和逆时针方向转动,利用这个特性来改善FFS/IPS模式液晶面板的大视角特性,避免了侧向观看液晶面板时出现的偏蓝或者偏黄现象。在本实施例中,像素电极Pl的所述的至少两个显示域的电位相同。

[0025]在本实施例中,相邻两像素区之间的区域33为空白区域。在其它实施方式中,相邻两像素区之间的区域33也可以布置有公共电极线,从而有效提升设计布线的灵活性。

[0026]参考图5、图6,其中图5为本发明另一实施例所述的液晶显示器件的像素结构示意图,图6为图5所示实施例中B区域的放大示意图;本实施例中适用于HVA模式的液晶面板。所述的液晶显示器件50具有多条水平方向延伸的栅极信号线Gl和多条竖直方向延伸的数据信号线Dl以阵列的形式垂直相交,以定义出多个像素区51,每一像素区51包括一液晶显示像素结构。本实施例中,所述的液晶显示像素结构包括:一像素电极Pl,一栅极信号线G1、一公共电极线C0M1、一数据信号线Dl以及一晶体管Tl;其中,像素电极Pl具有至少四个显示域。

[0027]像素电极P1,位于像素开口区内,像素电极Pl具有四个显示域1st Domain,2ndDomain,3rd Domaiη、4thDomaiη,以避免液晶面板在大视角观看时颜色偏黄和偏蓝的问题;其中,第一显示域和第二显示域(lst-2nd Domain)呈左右排列,第三显示域和第四显示域(3rd-4th Domain)呈左右排列。

[0028]栅极信号线G1,第一、第二显示域(lst_2nd Domain)配置于栅极信号线Gl的上方,且第一、第二显示域(lst_2nd Domain)的下边缘均与栅极信号线Gl重叠。

[0029] 公共电极线C0M1,第三、第四显示域(3Td-4th Domain)配置于公共电极线COMl的下方,且第三、第四显示域(3Td-4th Domain)的上边缘均与公共电极线COMl重叠。

[0030]也即,像素开口区被栅极信号线Gl和公共电极线COMl所隔开,栅极信号线Gl和公共电极线COMl位于第一、第二显示域(lst-2nd Domain)与第三、第四显示域(3rd-4th Domain)的交界处,且交界处的边缘分别与栅极信号线Gl和公共电极线COMl重叠。

[0031] 如图6所示,在交界处,第一、第二显示域(lst_2nd Domain)的下边缘61与栅极信号线Gl重叠,第三、第四显示域(3rd-4th Domain)的上边缘62与公共电极线COMl重叠。如此,通过使各显示域中液晶分子偏转无规律的部分均分别与栅极信号线和公共电极线重叠,借助栅极信号线和公共电极线本身是由不透光的金属材料制作所起到的遮光作用,避免了液晶面板正常工作时在像素开口区内形成暗纹,提高了像素的开口率和穿透率。且由于液晶分子转动异常的部分被不透光的栅极信号线和公共电极线所遮挡,也可以避免液晶面板受到按压时不同显示域交界处可能出现的显示异常情况,进一步提升液晶面板显示品质。

[0032]在其它实施方式中,所述的液晶显示像素结构也可以为包括:一像素电极Pl,一栅极信号线G1、一数据信号线Dl以及一晶体管Tl;其中,像素电极Pl具有至少四个显示域。栅极信号线G1,第一、第二显示域(lst_2nd Domain)配置于栅极信号线Gl的上方,且第一、第二显示域(lst-2nd Domain)的下边缘均与栅极信号线Gl重叠,第三、第四显示域(3rd-4thDomain)配置于栅极信号线Gl的下方,且第三、第四显示域(3rd-4th Domain)的上边缘均与所述栅极信号线Gl重叠。也即,像素开口区被栅极信号线Gl所隔开,栅极信号线Gl位于第一、第二显示域(lst-2nd Domain)与第三、第四显示域(3Td-4th Domain)的交界处,且交界处的边缘均与栅极信号线Gl重叠。如此,通过使各显示域中液晶分子偏转无规律的部分均与栅极信号线重叠,借助栅极信号线本身是由不透光的金属材料制作所起到的遮光作用,避免了液晶面板正常工作时在像素开口区内形成暗纹,提高了像素的开口率和穿透率。且由于液晶分子转动异常的部分被不透光的栅极信号线所遮挡,也可以避免液晶面板受到按压时不同显示域交界处可能出现的显示异常情况,进一步提升液晶面板显示品质。

[0033]数据信号线Dl,配置于像素开口区的边缘(如图5所示,Dl位于像素开口区左侧)。本发明由于每一像素电极仅配置一条数据信号线,且数据信号线位于像素电极的两侧(本实施例数据信号线位于左侧)而非贯穿于像素电极的中间,避免了因数据信号线的增加而带来的寄生电容大幅增加、驱动IC的温度升高、信赖性会受到影响的问题。

[0034]像素电极Pl通过晶体管Tl受栅极信号线Gl和数据信号线Dl的控制。也即,一个像素区内部只有一个TFT,晶体管所占的面积更小,有效提升了液晶面板的穿透率。

[0035]在本实施例中,四个显示域(lst_4th Domain)中像素电极Pl的延伸方向是不同的,在液晶面板点灯工作时,第一显示域1st Domain中的液晶分子沿与数据信号线Dl呈45度方向进行偏转;第二显示域2nd Domain中的液晶分子沿与数据信号线Dl呈135度方向进行偏转;第三显示域Yd Domain中的液晶分子沿与数据信号线Dl呈225度方向进行偏转;第四显示域4th Domain中的液晶分子沿与数据信号线Dl呈315度方向进行偏转。利用四个显示域(lst-4th Domain)中像素电极Pl的延伸方向不同的特性来改善HVA模式液晶面板的大视角特性,避免了侧向观看液晶面板时出现的偏蓝或者偏黄现象。在本实施例中,像素电极Pl的所述的至少四个显示域的电位相同。

[0036]在本实施例中,相邻两像素区之间的区域53为空白区域。在其它实施方式中,相邻两像素区之间的区域53也可以布置有公共电极线,从而有效提升设计布线的灵活性。

[0037]以上所述仅是本发明的优选实施方式,应当指出,对于本技术领域的普通技术人员,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
