Description

液晶显示器 技术领域
本发明涉及显示技术领域，尤其涉及一种液晶显示器。
背景技术
液晶显示装置(LCD，Liquid Crystal Display)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。如：液晶电视、移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕等。通常液晶显示装置包括壳体、设于壳体内的液晶显示面板及设于壳体内的背光模组(Backlight module)。其中，液晶显示面板的结构主要是由一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)、一彩色滤光片基板(Color Filter，CF)、以及配置于两基板间的液晶层(Liquid Crystal Layer)所构成，其工作原理是通过在两片玻璃基板上施加驱动电压来控制液晶层的液晶分子的旋转，将背光模组的光线折射出来产生画面。
量子点是半径小于或接近于波尔半径的半导体纳米晶体，大部分由Ⅱ-Ⅵ族或Ⅲ-Ⅴ族元素组成的三个维度尺寸纳米材料。由于量子限域效应，其内部的电子和空穴的运输受到限制，使得连续的能带结构变成分离的能级结构。当量子点的尺寸不同时，电子与空穴的量子限域程度不一样，分立的能级结构不同。在受到外来能量激发后，不同尺寸的量子点即发出不同波长的光，即各种颜色的光。量子点的优势在于：通过调控量子点的尺寸，可以实现发光波长范围覆盖到红外及整个可见光波段，且发射光波段窄，色彩饱和度高；量子点材料量子转换效率高；材料性能稳定；制备方法简单多样，可以从溶液中制备，资源丰富。
基于量子点的液晶显示器作为一种最有可能实现实用化的显示器件，在信息交流和传递等领域起着至关重要的作用。量子点的荧光强度和稳定性都很好，量子点显示器将拥有更佳的画质，更低的功耗，使用寿命更长的优势，很可能成为今后显示技术开发的主流方向之一。作为液晶显示屏的背光模组的发光源，在受到蓝光LED灯激发后发出的光与蓝光混色形成白光，其具有较大的色域，能很大程度提升画面显示品质
图1为一种现有液晶显示器的剖面示意图，包括背光模组100、及设于所述背光模组100上的液晶面板200；所述液晶面板200包括TFT基板210、与所述TFT基板210相对设置的玻璃基板220、设于所述TFT基板210上 的色阻层230、设于所述色阻层230上的像素电极层240、填充于所述TFT基板210与玻璃基板220之间的液晶层260、分别设于所述液晶层260两侧的配向层270、设于所述玻璃基板220上的黑色矩阵280、设于所述玻璃基板220上表面的上偏光片290、及设于所述TFT基板210下表面的下偏光片390，其中，所述色阻层230为采用量子点材料掺杂的色阻层。
图2为另一种现有液晶显示器的剖面示意图，包括背光模组100、及设于所述背光模组100上的液晶面板200；所述液晶面板200包括TFT基板210、与所述TFT基板210相对设置的玻璃基板220、设于所述玻璃基板220上的色阻层230、设于所述色阻层230上的像素电极层240、填充于所述TFT基板210与玻璃基板220之间的液晶层260、分别设于所述液晶层260两侧的配向层270、设于所述玻璃基板220上的黑色矩阵280、设于所述玻璃基板220上表面的上偏光片290、及设于所述TFT基板210下表面的下偏光片390，其中，所述色阻层230为采用量子点材料掺杂的色阻层。
然而，现有基于量子点的液晶显示器在具有诸多优点的同时，也有一定的不足。如在图1所示的液晶显示器中，光线经过采用量子点材料掺杂的色阻层230后，出射方向是随机的，当经过色阻层230后的发散光线穿过液晶层260时，不再能很好的控制相应像素点位的所有光线，液晶显示器就会发生漏光现象。而液晶显示器工作原理是利用液晶的旋光性和双折射，通过电压控制液晶的转动，使经过上偏光片后的线偏振光随之发生旋转，从下偏光片(与上偏光片垂直)射出。偏光片加上液晶盒起到光开关的作用。显然，这种光学开关对量子点发出的光线无法完全起到作用。
另外，传统的液晶显示器中的偏光片中常使用碘作为二向色性的物质，但是碘的升华性大，所以在耐热性和耐光性方面不佳，并且碘的消光色为深蓝色，所以它不是对整个可见光范围理想的无色偏光片，从而对液晶显示器的显示效果不利。
发明内容

其中，所述色阻层23为采用量子点材料掺杂的色阻层，所述偏光层25为采用有机染料分子制备的各向异性染料膜。
具体地，所述有机染料分子为具有偏光特性的染料分子。优选的，所述具有偏光特性的染料分子为三偶氮染料。具体地，所述三偶氮染料的结构式为：
Figure PCTCN2015079383-appb-000004
Figure PCTCN2015079383-appb-000005
或
Figure PCTCN2015079383-appb-000006
具体地，所述偏光层25可以采用喷墨、旋涂等溶液加工方法制备，也可以采用蒸镀的方式制备，并通过摩擦工艺得到高偏光度。
在该实施例中，通过在像素电极层24上设置一层由有机染料分子制备的各向异性偏光层25，使光线在进入液晶层26之前，对不同偏振态的光线进行选择性通过，得到线性偏振的光，有效解决了量子点材料造成的光偏振态改变而导致的漏光问题，使液晶可以在TFT开关的控制下起到光学开关的作用，防止漏光现象的发生，提高了对比度，并通过偏光层25取代了下偏光片，从而省去一道偏贴工艺，简化制程，节省成本，并且该偏光层25较传统的偏光片具有更好的偏振效果。
值得一提的是，所述黑色矩阵28也可以设置在与所述色阻层23同侧的位置，即设于所述阵列基板上。此时，所述黑色矩阵28的高度需要形成一面挡墙，防止色阻层23混色状况的发生。
请参阅图4，为本发明的液晶显示器的第二实施例的剖面示意图。所述液晶显示器包括背光模组1、及设于所述背光模组1上的液晶面板2。
具体地，所述液晶面板2包括阵列基板、设于阵列基板下方的下偏光片39、设于阵列基板上方的CF基板、及设于所述阵列基板与CF基板之间的液晶层26。
具体地，所述阵列基板包括第一玻璃基板20、设于第一玻璃基板20上的TFT层21、设于所述TFT层21上的第一配向层271；所述CF基板包括第二玻璃基板22、设于第二玻璃基板22上的黑色矩阵28、设于黑色矩阵28上的色阻层23、设于所述色阻层23上的公共电极层24、设于所述公共电极层24上的偏光层25、及设于偏光层25上的第二配向层272，所述阵列基板上的第一配向层271与所述CF基板上的第二配向层272相向设置， 所述液晶层26位于所述第一配向层271与第二配向层272之间。

在该实施例中，通过采用有机染料分子制备的偏光层25取代了上偏光片，从而省去一道偏贴工艺，简化制程，节省成本，并且该偏光层25的偏振效果优于传统的采用碘作为二向色物质制作的偏光片。
请参阅图5，为本发明的液晶显示器的第三实施例的剖面示意图。其与第二实施例的不同之处在于，所述液晶面板2还包括设于CF基板上方的上偏光片29。在图4所示的液晶面板2的结构中，由于色阻层23位于第二玻璃基板22上，靠近出光外界面，环境光线很容易入射进来，激发到色阻层23中的量子点导致不必要光线的产生，影响器件的画面品质。因此，在CF基板的第二玻璃基板22上远离黑色矩阵28和色阻层23一侧增加一层上偏光片或者制备一层薄膜在表面上，可以防止环境光线的干扰作用。
综上所述，本发明的液晶显示器，通过在色阻层中掺杂量子点材料，使量子点受背光的激发，形成一定光谱的光线，并搭配由有机染料分子制备的各向异性偏光层，对不同偏振态的光线进行选择性通过，得到线性偏振的光，有效解决了量子点材料造成的光偏振态改变而导致的漏光问题，提高了对比度，并可通过该偏光层取代上或下偏光片，从而省去一道偏贴工艺，简化制程，节省成本，同时实现更好的偏振效果。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明后附的权利要求的保护范围。
