Description

显示器 技术领域
本发明涉及显示技术领域，尤其涉及一种量子棒显示器。
 背景技术
量子点（Quantum Dots，简称QD）是肉眼看不到的，极其微小的无机纳米晶体。每当受到光的刺激，量子点便会发出非常纯净的有色光线。使用量子点材料的背光源是目前色彩最纯净的背光源。量子点电视使用色彩最纯净的量子点光源作为背光源，革命性的实现全色域显示，最真实还原图像色彩。量子点有一个与众不同的特性：每当受到光或电的刺激，量子点便会发出有色光线，光线的颜色由量子点的组成材料和大小形状决定，一般颗粒若越小，会吸收长波，颗粒越大，会吸收短波。2纳米大小的量子点，可吸收长波的红色，显示出绿色，8纳米大小的量子点，可吸收短波的蓝色，呈现出红色。这一特性使得量子点能够改变光源发出的光线颜色。
如图1所示，为现有技术的量子点液晶显示器，包括自下而上依次设置的反射片101、导光板102、光学膜片103、下偏光板104、阵列基板105、液晶层106、量子点发光层107、色阻层108、黑色矩阵112、彩膜基板109及上偏光片110，导光板102的入光侧设置蓝色光源111；由于量子点发光具有非偏振特性，经过下偏光板的线性偏振蓝光激发彩膜光阻中的量子点后，其发出的光具有各种不同的偏振特性，无论用于激发的蓝光具有何种偏振特性，被激发的量子点始终有一半的光辉通过上偏光板，难以实现全暗态或黑画面显示，因而无法通过液晶的偏振改变特性实现对显示亮度地控制。
综上所述，现有技术的量子点液晶显示器，无法有效地控制量子点发光的非偏振特性，导致液晶显示面板难以实现全暗态或黑画面显示，以及显示亮度效率低的技术问题，进而影响了画面显示效果。

 附图说明
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图2为本发明的显示器的结构示意图；
图3为图2的优选方案结构示意图；
图4为量子棒材料的配向方法流程图。
 本发明的最佳实施方式
以下各实施例的说明是参考附加的图示，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
本发明针对现有的量子点液晶显示器，无法有效地控制量子点发光的非偏振特性，导致液晶显示面板难以实现全暗态或黑画面显示，以及显示亮度效率低，进而影响了画面显示效果的技术问题，本实施例能够解决该缺陷。
如图2所示，本发明的显示器，包括有背光模组及位于所述背光模组上方的液晶显示面板。
所述背光模组包括导光板、位于所述导光板下表面的反射片、位于所述导光板上表面的光学膜片以及位于所述导光板的入光侧的蓝色光源，所述光学膜片上设置有下偏光板。
所述液晶显示面板包括阵列基板212及彩膜基板202，所述阵列基板212与所述彩膜基板之间设置有液晶层201，所述彩膜基板202上表面的制备有色阻层203与第一黑色矩阵204，所述色阻层203表面制备有平坦层205，所述平坦层205表面制备有量子棒发光层。
所述量子棒发光层包括若干阵列分布的隔离件206，每一所述隔离件206中形成一凹部，所述凹部内填充有量子棒材料，所述量子棒发光层上设置有上偏光板207；优选的，所述凹部的开口尺寸与相对应的子像素的开口相对应；优选的，在所述量子棒发光层表面涂布水氧阻绝层208，用以防止水氧对量子棒光电性质及寿命产生影响。
所述色阻层203被所述第一黑色矩阵204划分若干个红色（R）、绿色（G）及蓝色（B）子像素，每一所述隔离件206，分别对应位于一子像素上方；所述隔离件206内的量子棒材料的颜色，与位于其下方的的子像素颜色相对应，即红色子像素上方对应设置红色量子棒材料209，绿色子像素上方对应设置绿色量子棒材料210，蓝色子像素上方则对应设置透明材料211。
以常黑设置、且上下偏光片与下偏光片的透过轴方向互相垂
直设定为例，所述量子棒的取向与上偏光片的透光轴方向一致；背光源发出的蓝光经过下偏光片形成偏振光，液晶处于关态电压时，蓝光经过液晶层201后的偏振方向保持不变，也即蓝光的偏振方向垂直于所述量子棒的排列方向，无法有效激发量子棒发光，因而无光线透过所述上偏光片形成黑态输出；当液晶上下施加开态电压时，偏振蓝光经过液晶层201后的偏振方向平行于上偏光片的透过轴方向，也即与所述量子棒的排列方向一致，因而能够最大程度地激发量子棒发光，并顺利透过上偏光片形成白态输出；显然白态时，蓝光分别激发红色量子棒、绿色量子棒，从而分别形成红、绿、蓝图案输出，期间输出光偏振态与上偏光片一致，没有能量损耗，因而相对于传统彩膜光阻结构的穿透率有大幅提升，具有极佳的亮度效率，同时具有高色域的特性。
所述量子棒为核壳结构，所述量子棒中心具有一量子点；所述量子棒主要由Ⅱ-Ⅵ族半导体材料(如：CdS、CdSe、HgTe、ZnS、ZnSe、ZnTe、HgS等)、Ⅲ-Ⅴ族半导体材料(如：InP、InAs、GaP、GaAs等)或Ⅳ-Ⅵ族纳米半导体材料组成的核壳结构的量子棒，上述量子点的粒径最优选在1-10nm之间，其中红、绿量子棒对应的量子点粒径不同，从而通过不同程度的量子限制效应实现不同波长的发射；量子棒配体可选择常用的量子点配体如三正辛基膦(TOP)、三正辛基氧化膦(TOPO)等中的一种。
所述量子棒具有与量子点类似的窄线宽发射特性，其波长与
材料、量子点尺寸相关，因而可以作为理想的高色域背光使用；不同于传统的量子点结构，由于量子棒横向具有较大的尺寸，其对于核心的量子点发光发挥光调制作用，从而使得量子棒的发光通常具有偏振选择特性，通常其偏振方向平行于量子棒的取向，其偏振度可以达到0.7，意味着仅有少量的发光具有与量子棒取向垂直的偏振态，偏振方向平行于量子棒取向的发光具有更高的量子效率。
所述隔离件206为SU-8光刻胶，在可见光波段为透明材料211；SU-8光刻胶是一种化学增幅型负性光刻胶，具有良好的光敏性和高深宽比,它既克服了普通光刻采用UV光刻深宽比不足的问题，又不存在工艺成本高的问题；它对紫外线具有低光光学吸收特性,既使膜厚高达1000微米,所得图形边缘仍近乎垂直。
如图3所示，量子棒膜需要相当的膜厚才能保证足够的光
效，所述SU-8隔离件206的厚度约为10～30μm，大于传统液晶模组的间隙厚度，因而在光线通过液晶盒的过程中容易出现不同子像素之间的颜色串扰，从而形成大视角色偏，因此在所述水氧阻绝层208表面制备第二黑色矩阵213，从而降低大视角色偏，所述第二黑色矩阵213的开口位置与所述第一黑色矩阵204的开口位置相匹配。
所述量子棒材料中的量子棒均沿同一方向排列，且其排列方向与位于所述彩膜基板202上表面的上偏光片的透过轴方向一致，量子棒材料的配向原理与液晶的配向原理类似。
如图4所示，量子棒材料的具体配向步骤如下：S101、将所述彩膜基板202放入一容器中，所述容器横向设置一定数量的电极；S102、通过施加不同的偏压在所述彩膜基板202表面生成横向电场，使得所述量子棒沿着电场方向排布；S103、采用UV或者热固化方式使得量子棒取向固定。
本发明的有益效果为：相较于现有的量子液晶显示器，本发明的显示器，在液晶面板外表面设置具有偏振特性的量子棒发光层，利用量子棒激发与荧光光谱的偏振特性结合液晶的偏振改变功能，以实现量子点电视具有高亮度、高色域液晶的显示效果。
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。
