Description

液晶显示装置
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装置。
背景技术
液晶显示装置(LCD，LiquidCrystalDisplay)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括液晶显示面板及背光模组(backlightmodule)。所述背光模组为液晶显示面板提供光源，所述液晶显示面板通过信号驱动进一步控制光线的通过量，经由有色光阻将通过的光线过滤为红绿蓝三基色，通过对三基色的光强的调节搭配以实现不同亮度及色彩的显示。
图1为现有的一种液晶显示面板的剖面示意图，图2为图1的液晶显示面板的立体分解示意图，如图1和图2所示，所述液晶显示面板包括CF基板100、与CF基板100相对设置的TFT基板200、设于所述CF基板100与TFT基板200之间的液晶层300、设于所述CF基板100上方的上偏振片400、设于所述下基板200下方的下偏振片500、及设于所述CF基板100与TFT基板200之间边缘位置的边框胶(未图示)；所述CF基板100包括玻璃基板110、设于所述玻璃基板110上的彩色光阻层120及黑色矩阵130、以及设于所述黑色矩阵120上方且对应所述黑色矩阵120设置的光阻间隙物140等；所述TFT基板200包括玻璃基板210、设于所述玻璃基板210上的TFT层220、设于所述TFT层220上的配向膜230等。
液晶显示面板的工作过程是通过TFT基板200与CF基板100上的电极控制像素区域的液晶分子转动使得透射光的偏振态发生相应改变，配合所述TFT基板200与CF基板100两侧的上、下偏振片400、500达到控制透光量的目的；CF基板100则是将透过液晶层300的光线进行过滤吸收，使得每个像素区域的光在射出液晶显示面板后都是由三基色(或四色)构成。
但是CF基板100只可以让部分波段的光线通过，且需要借助上偏光片400对光线进行偏振，所以通过CF基板100之后的光强会衰减为原来的约33％，这是目前LCD光效率较低的原因之一。
随着科技的发展及客户需求的提升，为追求更高的显示画质，对彩色滤光膜的滤光能力提出了较高的要求，但受限于背光源的频谱及色阻材料本身的特性限制，色彩的表现能力受到了较大的限制。现在兴起的有机发光材料与量子点(quantumdot，QD)材料在发光方面具有很大的优势。量子点基于其量子受限的原理，对于指定的量子点其在特定的尺寸时其发光波长是唯一确定的，且其结构特点决定其发射光的频段极窄，半高宽(fullwidthathalfmaximum，FWHM)可达20nm，通过调控材料的合成尺寸即可获得RGB三个不同波段的发射光。利用量子点优异的发光特性可以实现对发光光谱的优化从而得到高色域显示及高色彩纯度，对显示性能的提高有很大帮助。
发明内容
本发明的目的在于提供一种液晶显示装置，其液晶显示面板的结构简单，与传统的液晶显示面板相比，省去了彩色光阻层、及上偏光片等部件，结构简单，制作成本低，同时该液晶显示面板的色彩显示品质好，光线透过率高，有效提高了液晶显示装置的光能利用率及显示性能。

具体实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图3至图5，本发明首先提供一种液晶显示装置，包括液晶显示面板及背光源；
所述液晶显示面板包括上基板10、与上基板10相对设置的下基板20、设于所述下基板20下方的偏振片30、及设于所述上、下基板10、20之间边缘位置的边框胶(未图示)。
所述上基板10包括第一透明基板11、设于所述第一透明基板11上的黑色矩阵12、以及设于所述黑色矩阵12上方且对应所述黑色矩阵12设置的色阻挡墙13；
具体的，如图4所示，所述黑色矩阵12包括数条横向遮光带121、及与所述数条横向遮光带121垂直交叉排列的数条纵向遮光带122；如图5所示，所述色阻挡墙13包括分别对应最外侧的两条横向遮光带121设置的两条横向色阻挡墙131、及分别对应所述数条纵向遮光带122设置的数条纵向色阻挡墙132，所述两条横向色阻挡墙131与数条纵向色阻挡墙132在所述第一透明基板11上围成数个条形槽14。
具体的，所述数个条形槽14包括红色条形槽141、绿色条形槽142、及蓝色条形槽143；所述红色条形槽141、绿色条形槽142、及蓝色条形槽143内分别设置有不同的混合液晶材料，在背光源的照射下分别发出红、绿、蓝光。
具体的，所述色阻挡墙13的高度将由液晶显示面板的盒厚所决定，其制程条件及对应材质同现有技术中的光阻间隙物类似。
所述下基板20包括第二透明基板21、设于所述第二透明基板21上的TFT层22、及设于所述TFT层22上的配向膜23。
优选的，所述上基板10中的第一透明基板11与所述下基板20中的第二透明基板21均为玻璃基板。
具体的，当所述背光源为蓝紫色LED灯或激光光源时，所述红色条形槽141内的混合液晶材料为液晶、二色性染料、及红光量子点的混合物，所述绿色条形槽142内的混合液晶材料为液晶、二色性染料、及绿光量子点的混合物，所述蓝色条形槽143内的混合液晶材料为液晶、二色性染料、及蓝光量子点的混合物；所述红色条形槽141内的红光量子点、所述绿色条形槽142内的绿光量子点、及所述蓝色条形槽143内的蓝光量子点在蓝紫光或激光的照射下分别发出红、绿、蓝光。
具体的，当所述背光源为蓝色LED灯时，所述红色条形槽141内的混合液晶材料为液晶、二色性染料、及红光量子点的混合物，所述绿色条形槽142内的混合液晶材料为液晶、二色性染料、及绿光量子点的混合物，所述蓝色条形槽143内的混合液晶材料为液晶与二色性染料的混合物；所述红色条形槽141内的红光量子点、及绿色条形槽142内的绿光量子点分别在蓝光的照射下发出红、绿光；所述蓝色条形槽143内没有设置量子点，从而使蓝光透过，发出蓝光。
具体的，所述红色条形槽141、绿色条形槽142、及蓝色条形槽143内的混合液晶材料均采用物理方法混合均匀，例如，采用搅拌机进行机械搅拌或者采用超声振荡的方式进行混合。
具体的，对于混合液晶材料为液晶、二色性染料、及量子点的混合物的情况，将所述混合液晶材料注入到条形槽14中后，量子点会与液晶及二色性染料发生分离而附着在条形槽14的底部，光线在经过液晶及二色性染料后会经过量子点转换成RGB三色的光，代替了RGB色阻的作用，且量子点的自聚集行为，会产生与配向膜相近的作用，其形成的链状结构会使液晶产生配向力，即可代替配向膜的配向作用。
具体的，所述二色性染料为偶氮类化合物或蒽醌类化合物。
具体的，本发明采用的红、绿、蓝光量子点为半导体纳米晶量子点或其他光致发光的纳米颗粒。
具体的，当本发明的液晶显示面板为VA(VerticalAlignment，垂直取向)型液晶显示面板时，所述上基板10还包括设于所述第一透明基板11与黑色矩阵12之间的公共电极层；所述下基板20还包括设于所述TFT层22与配向膜23之间的像素电极层。此外，对于VA模式来说，由于量子点的自聚集效应，可以对液晶产生配向作用，因此，所述上基板10中可以不设置配向膜，仅依靠量子点的自聚集效应对液晶进行配向，也可以在所述上基板10的条形槽14的底部设置配向膜，从而进一步提高配向的效果。
具体的，当本发明的液晶显示面板为IPS(In-PlaneSwitching，平面转换)或FFS(FringeFieldSwitching，边缘场开关)型液晶显示面板时，所述下基板20还包括设于所述TFT层22与配向膜23之间的像素电极层与公共电极层；所述上基板10还包括设于所述第一透明基板11上的配向膜。
本发明采用的二色性染料具有偏振功能，该二色性染料与液晶混合后，在电场的作用下随液晶分子的转动而转动，与液晶分子的取向保持一致，具体的，所述二色性染料在液晶中的工作原理如下：
请参阅图6，当入射光无特定偏振方向，且液晶分子122与二色性染料分子123垂直于上、下基板10、20排列时，此时二色性染料分子123对光线的吸收作用最弱，光线几乎全部通过液晶层；
请参阅图7，图中叉号表示入射光的偏振方向垂直于纸面，当入射光的偏振方向垂直于纸面，且液晶分子122与二色性染料分子123平行于上、下基板10、20排列时，入射光的偏振方向与二色性染料分子123的吸收轴垂直，所述二色性染料分子123对光线的吸收作用最弱，光线几乎全部通过液晶层；
请参阅图8，图中黑色双箭头表示入射光的偏振方向平行于纸面，当入射光的偏振方向平行于纸面，且液晶分子122与二色性染料分子123平行于上、下基板10、20排列时，入射光的偏振方向与二色性染料分子123的吸收轴平行，所述二色性染料分子123对光的吸收作用最强，光线几乎完全被二色性染料分子123吸收，最后透过液晶层后，光强为零。
根据以上原理，在本发明的液晶显示面板结构中便可以只使用一张偏光片30即可达到控制光强的作用，具体的，所述偏光片30设置于下基板20远离上基板10的一侧，具体的，该偏光片30的透光轴方向对应不同的液晶显示模式设置：
当本发明的液晶显示面板为VA型液晶显示面板时，设置所述偏光片30的透过轴方向平行于液晶分子加电时的配向方向；
如图9所示，液晶层两侧不加电时，液晶分子122与二色性染料分子123垂直于上、下基板10、20排列，所述入射光的偏振方向与二色性染料分子123的吸收轴垂直，所述二色性染料分子123对光线的吸收作用最弱，光线几乎完全通过液晶层，液晶显示面板处于亮态；
如10所示，对液晶层两侧加电后，液晶分子122与二色性染料分子123平行于上、下基板10、20排列，所述入射光的偏振方向与二色性染料分子123的吸收轴平行，所述二色性染料分子123对光线的吸收作用最强，光线几乎完全被二色性染料分子123吸收，最后透过液晶层后，光强为零，液晶显示面板处于暗态。
当本发明的液晶显示面板为IPS或FFS型液晶显示面板时，设置所述偏光片30的透过轴方向平行或垂直于液晶分子不加电时的水平配向方向；
如图11所示，所述偏光片30的透过轴方向平行于液晶分子不加电时的水平配向方向，对液晶层不加电时，二色性染料分子123的吸收轴与入射光的偏振方向平行，所述二色性染料分子123对光线的吸收作用最强，光线几乎完全被二色性染料分子123吸收，最后透过液晶层后，光强为零，液晶显示面板处于暗态；对液晶层施加电压后，随着电压的增大，液晶分子同二色性染料分子123在电场的作用下逐渐旋转，随着二色性染料分子123的吸收轴与入射光偏振方向夹角逐渐接近90°，二色性染料分子123对光线的吸收作用逐渐减弱，当二色性染料分子123的吸收轴与入射光偏振方向垂直时，二色性染料分子123对光线的吸收效果最弱，液晶显示面板处于亮态；
如图12所示，所述偏光片30的透过轴方向垂直于液晶分子不加电时的水平配向方向，对液晶层不加电时，二色性染料分子123的吸收轴与入射光的偏振方向垂直，所述二色性染料分子123对光线的吸收作用最弱，光线几乎完全通过液晶层，液晶显示面板处于亮态；对液晶层施加电压后，液晶分子同二色性染料分子123在电场的作用下逐渐旋转，随着二色性染料分子123的吸收轴与入射光偏振方向逐渐接近平行，二色性染料分子123对光线的吸收作用逐渐增强，当二色性染料分子123的吸收轴与入射光偏振方向平行时，二色性染料分子123对光线的吸收效果最强，液晶显示面板处于暗态。
综上所述，本发明提供的一种液晶显示装置，通过在液晶中混入具有不同发光波段的量子点，来代替CF基板上的彩色光阻层，使得液晶显示面板在没有彩色光阻层的情况下依然可以发出RGB三色的光，同时通过在液晶中混入具有偏振功能的二色性染料，减少了一片偏光板的设置，与传统的液晶显示面板相比，本发明的液晶显示面板由于省去了彩色光阻层、及上偏光片等部件，结构简单，制作成本低，同时该液晶显示面板的色彩显示品质好，光线透过率高，有效提高了液晶显示装置的光能利用率及显示性能。
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。
