Description

液晶显示面板及其应用的显示装置 技术领域
本发明涉及一种液晶显示技术,特别是涉及一种液晶显示面板及其应用的显示装置。
背景技术
液晶显示器(Liquid Crystal Display,LCD)已被广泛应用于各种电子产品中,液晶显示器大部分为背光型液晶显示器,其是由液晶显示面板及背光模块(backlight module)所组成。液晶显示面板是由两片透明基板以及被封于基板之间的液晶所构成,液晶显示面板具有多个像素,用于显示影像。
目前,在大尺寸的液晶显示面中,为了实现低色偏(Low color shift),液晶显示面板的每一像素会分成不同区域,且不同区域之间具有电位差,以减少色偏问题。
然而,为在上述像素的不同区域之间形成电位差,每一像素需设有三个薄膜晶体管(Thin Film Transistor,TFT)及二条栅极线来控制像素的充电,因而大幅地降低像素的开口率。
故,有必要提供一种液晶显示面板及其应用的显示装置,以解决现有技术所存在的问题。

请参照图1,其显示依照本发明的一实施例的液晶显示面板的局部剖面示意图。本实施例的显示装置可包括液晶显示面板100和背光模块(未绘示)。液晶显示面板100相对于背光模块来设置,此背光模块可为侧光式(side Lighting)背光模块或直下式入光(Bottom Lighting)背光模块,以提供背光至液晶显示面板100。
如图1所示,液晶显示面板100可包括第一基板110、第二基板120、液晶层130、第一偏光片140及第二偏光片150。液晶层130是形成于第一基板110及第二基板120之间,亦即液晶层130是位于第一基板110及第二基板120的内侧。第一偏光片140是设置于第一基板110的外侧,并相对于液晶层130(亦即为第一基板110的出光侧)。第二偏光片150是设置于第二基板120的外侧,并相对于液晶层130(亦即为第二基板120的入光侧)。
如图1所示,第一基板110和第二基板120的基板材料可为玻璃基板或可挠性塑料基板,第一基板110可例如为具有彩色滤光片(Color Filter,CF)的玻璃基板或其它材质的基板,而第二基板120可例如为具有薄膜晶体管(Thin Film Transistor,TFT) 矩阵的玻璃基板或其它材质的基板。值得注意的是,在一些实施例中,彩色滤光片和TFT矩阵亦可配置在同一基板上。
如图1所示,第一基板110可包括第一电极层111,第二基板120可包括第二电极层121。第一电极层111和第二电极层121优选是以透光导电材料所制成,例如:ITO、IZO、AZO、GZO、TCO或ZnO,第一电极层111和第二电极层121可施加电压于液晶层130的液晶分子。在本实施例中,第一电极层111例如为共同电极,第二电极层121例如为像素电极。
请参照图2,其显示依照本发明的一实施例的液晶显示面板的像素的布线图。第二基板120包括更多条信号线122、多个主动元件123及多个像素124。信号线122例如为栅极线及数据线,且相互垂直交错,因而形成矩阵式排列的像素124。主动元件123例如为薄膜晶体管(Thin Film Transistor,TFT),分别设置于像素124中,并电性连接于信号线122及像素124的像素电极。每一像素124可对应于一种颜色的滤光片,例如红、绿或蓝色滤光片。
请参照图2及图3,图3显示图2的部分放大视图。每一像素124包括一主像素区101及一次像素区102,其中次像素区102的面积可大于主像素区101的面积。每一主像素区101的像素电极结构包括第一主干103及多个第一分支104,每一次像素区102的像素电极结构包括第二主干105及多个第二分支106。第一主干103及第二主干105可呈十字形图案。在每一像素124中,主动元件123的其中一者是位于主像素区101及次像素区102之间,且主动元件123是分别连接于主像素区101中的第一主干103及次像素区102的第二主干105。分支104、106是分别由主干部103、105来倾斜地延伸出,并相互平行排列。其中,主像素区101中的第一分支104具有相同的第一线宽L1及第一线距S1,次像素区102中的第二分支106具有相同的第二线宽L2及第二线距S2,且第一线宽L1及第一线距S1之间的第一比例(L1/S1)是不同于第二线宽L2及第二线距S2之间的第二比例(L2 /S2)。在此,线宽表示为分支的宽度,而线距表示为分支之间的距离。
请参照图4,其显示依照本发明的一实施例的液晶显示面板的像素的分支的线宽/线距及液晶效率之间的关系示意图。如图4所示,线A表示线宽为1微米(um)的分支在不同线距及液晶效率(LC Efficiency)之间的关系,B表示线宽为2 um的分支在不同线距及液晶效率之间的关系,C表示线宽为3um的分支在不同线距及液晶效率之间的关系。因此,如图4所示,当分支具有不同的线宽及/或线距时,液晶显示面板100可具有不同的液晶效率。
因此,通过控制线宽及线距的比例,在每一像素124中,主像素区101及次像素区102可具有不同的液晶效率,使得主像素区101及次像素区102可具有不同亮度表现,而可达到低色偏的目的。
在本实施例中,每一第一分支104或第二分支106的线宽L1或L2可小于7 um,例如是介于1 um与7 um之间,且每一第一分支104或第二分支106的线距S1或S2可小于7 um,例如是介于1 um与7 um之间。又,第一比例(L1/S1)或第二比例(L2 /S2)的比例值可介于0.2~5,例如介于0.2~0.9或介于2.6~5,以有效地改善色偏问题。
在一实施例中,主像素区101中的第一分支104的线距S1可相同于次像素区102中第二分支106的线距S2(例如3um),而第二分支106的线宽L2(例如5um)是大于第一分支104的线宽L1(例如3um)。依据图4所示的关系,此时,主像素区101的液晶效率可高于次像素区102的液晶效率,使得主像素区101及次像素区102具有不同亮度表现,而可达到低色偏的目的。
在另一实施例中,主像素区101中的第一分支104的线宽L1可相同于次像素区102中第二分支106的线宽L2,而第二分支106的线距S2是大于第一分支104的线距S1。依据图4所示的关系,此时,主像素区101的液晶效率可高于次像素区102的液晶效率,使得主像素区101及次像素区102具有不同亮度表现,而可达到低色偏的目的。
在又一实施例中,主像素区101中第一线宽L1及第一线距S1之间的第一比例(L1/S1)可等于1,而次像素区102中第二线宽L2及第二线距S2之间的第二比例(L2 /S2)可大于或小于1(亦即不等于1)。此时,主像素区101的液晶效率可不同于次像素区102的液晶效率,使得主像素区101及次像素区102具有不同亮度表现,而可达到低色偏的目的。
由上述可知,在本发明的液晶显示面板及其应用的显示装置中,通过主像素区与次像素区之间的不同线宽/线距的比例,使得每一像素中的主像素区及次像素区可具有不同的液晶效率,亦即每一像素中的不同区域可具有不同亮度表现,而可达到低色偏的目的。由于本发明的液晶显示面板的每一像素可仅设有一个主动元件(TFT),因而可同时实现低色偏,并确保像素的开口率。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
