附图说明
通过结合附图进行的以下描述,本实用新型的实施例的上述和其它方面、特点和优点将变得更加清楚,附图中:
图1是根据本发明的第一实施例的液晶显示器的结构示意图;
图2是根据本发明的第二实施例的液晶显示器的结构示意图;
图3是根据本发明的第三实施例的液晶显示器的结构示意图;
图4是根据本发明的第四实施例的液晶显示器的结构示意图。
具体实施方式
以下,将参照附图来详细描述本发明的实施例。然而,可以以许多不同的形式来实施本发明,并且本发明不应该被解释为限制于这里阐述的具体实施例。相反,提供这些实施例是为了解释本发明的原理及其实际应用,从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在附图中,为了清楚器件,夸大了层和区域的厚度。相同的标号在附图中始终表示相同的元件。
图1是根据本发明的第一实施例的液晶显示器的结构示意图。
参照图1,根据本发明的第一实施例的液晶显示器包括:液晶面板100、与该液晶面板100相对设置的背光模块200、设置在液晶面板100与背光模块200之间的量子棒膜片300以及设置在量子棒膜片300与液晶面板100之间的波长膜片400;其中,背光模块200产生的背光依次通过量子棒膜片300和波长膜片400到达液晶面板100,以使液晶面板100显示影像。在本实施例中,优选地,背光模块200产生蓝色背光,但本发明并不限制于此,例如背光模块200也可产生紫外背光。
量子棒是二维限域的纳米级材料,由于电子和空穴被量子限域,连续的能带结构变成具有分子特性的分立能级结构,受激后可以发射荧光。量子棒与三维限域量子点的最大区别在于,其自吸收性小,同时激发光为偏振光,其偏振方向与量子棒排列方向相同。而根据本发明的第一实施例的液晶显示器,利用了量子棒的上述特性来提高液晶显示器的色彩饱和度。
继续参照图1,液晶面板100包括:液晶盒110、设置在液晶盒110之上的上偏光片120以及设置在液晶盒110之下的下偏光片130;其中,上偏光片120的偏振方向与下偏光片130的偏振方向垂直。
在本实施例中,液晶盒110可包括薄膜晶体管阵列基板、设置在薄膜晶体管阵列基板之上的彩色滤光片基板以及夹设在这两个基板之间的液晶层。
量子棒膜片300包括:多张绿色量子棒膜片310、多张红色量子棒膜片320及多张蓝色量子棒膜片330;其中,红色量子棒膜片320和蓝色量子棒膜片330交替且间隔设置,而绿色量子棒膜片310设置于红色量子棒膜片320和蓝色量子棒膜片330之间的间隔处。

这样,当背光模块200产生的背光激发绿色量子棒膜片310、红色量子棒膜片320及蓝色量子棒膜片330之后,由红色量子棒膜片320出射的光与由蓝色量子棒膜片330出射的光的偏振方向一致,而二者与由绿色量子棒膜片310出射的光的偏振方向垂直;由绿色量子棒膜片310出射的光通过半波长膜片420之后,其偏振方向被旋转90°,而由红色量子棒膜片320出射的光和由蓝色量子棒膜片330出射的光分别经过各自相对的全波长膜片410之后,它们的偏振光方向不变;此时,经过波长膜片400之后的光的偏振方向都与下偏光片130的偏振方向一致,因此都可通过下偏光片130。而在这个过程中,由绿色量子棒膜片310出射的光无法通过全波长膜片410之后到达下偏光片130,同样由红色量子棒膜片320出射的光与由蓝色量子棒膜片330出射的光也都无法通过半波长膜片420后到达下偏光片130,这样将有效阻止三种颜色光之间的干扰,从而提高液晶面板100出射三种颜色光的纯度,进而能够进一步地提高液晶面板100显示色彩的色域饱和度。
图2是根据本发明的第二实施例的液晶显示器的结构示意图。
参照图2,与图1所示的第一实施例不同的是,在本实施例中,每张绿色量子棒膜片310都分别相对于一张全波长膜片410,每张红色量子棒膜片320都分别相对于一张半波长膜片420,每张蓝色量子棒膜片330也分别都相对于一张半波长膜片420。
此外,进一步地,绿色量子棒膜片310的排列方向与液晶面板100的下偏光片130的偏振方向平行或一致,红色量子棒膜片320和蓝色量子棒膜片330的排列方向都与液晶面板100的下偏光片130的偏振方向垂直。也就是说,红色量子棒膜片320的排列方向和蓝色量子棒膜片330的排列方向平行或一致,而绿色量子棒膜片310的排列方向与二者垂直。
这样,当背光模块200产生的背光激发绿色量子棒膜片310、红色量子棒膜片320及蓝色量子棒膜片330之后,由红色量子棒膜片320出射的光与由蓝色量子棒膜片330出射的光的偏振方向一致,而二者与由绿色量子棒膜片310出射的光的偏振方向垂直;由绿色量子棒膜片310出射的光通过全波长膜片410之后,其偏振方向不变,而由红色量子棒膜片320出射的光和由蓝色量子棒膜片330出射的光分别经过各自相对的半波长膜片420之后,它们的偏振光方向都被旋转90°;此时,经过波长膜片400之后的光的偏振方向都与下偏光片130的偏振方向一致,因此都可通过下偏光片130。而在这个过程中,由绿色量子棒膜片310出射的光无法通过半波长膜片420之后到达下偏光片130,同样由红色量子棒膜片320出射的光与由蓝色量子棒膜片330出射的光也都无法通过全波长膜片410后到达下偏光片130,这样将有效阻止三种颜色光之间的干扰,从而提高液晶面板100出射三种颜色光的纯度,进而能够进一步地提高液晶面板100显示色彩的色域饱和度。
