Description

显示面板及其制备方法、显示装置
本申请要求于2019年11月07日提交中国专利局、申请号为201911080304.2、发明名称为“显示面板及其制备方法、显示装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及显示技术领域，具体涉及一种显示面板及其制备方法、显示装置。
 背景技术
目前比较成熟的透明显示器是基于传统的液晶面板技术，但因为偏光片的存在，其透过率提升有限。
为了提高透明显示器的透过率，引入聚合物网络液晶（Polymer Network Liquid Crystal，PNLC），通过不同电压下PNLC透过率的变化，实现灰阶的变化，进而去掉偏光片，大幅提高透明显示器的透过率。
 技术问题

目前比较成熟的透明显示器是基于传统的液晶面板技术，但因为偏光片的存在，其透过率提升有限。
为了提高透明显示器的透过率，引入聚合物网络液晶（Polymer Network Liquid Crystal，PNLC），通过不同电压下PNLC透过率的变化，实现灰阶的变化，进而去掉偏光片，大幅提高透明显示器的透过率；但是这种技术，在提高透过时率的同时，因为去掉了偏光片，导致对比度相对于传统的液晶显示器会大幅降低，影响其实际应用性能。
基于此，本发明实施例提供一种显示面板及其制备方法、显示装置，以下分别进行详细说明。
首先，本发明实施例中提供一种显示面板，所述显示面板包括第一基板、第二基板和液晶层，所述第一基板和所述第二基板相对设置，所述液晶层设置于所述第一基板和所述第二基板之间，所述液晶层包括多个二色性染料液晶微滴。
如图1所示，为本发明实施例中显示面板的一个实施例结构示意图，其中，该显示面板包括第一基板101、第二基板102和液晶层103，所述第一基板和所述第二基板相对设置，所述液晶层设置于所述第一基板和所述第二基板之间，所述液晶层包括多个二色性染料液晶微滴104。
具体的，所述图1所述为显示面板在无信号传输时的状态，所述液晶材料将处于无规则状态，所述二色性染料的吸光轴与寻常光的偏振方向平行时，所述二色性染料会强烈吸收光，进而降低显示面板的暗态透过率。
本发明实施例中通过提供一显示面板，该显示面板包括：第一基板、第二基板和液晶层，所述第一基板和所述第二基板相对设置，所述液晶层设置于所述第一基板和所述第二基板之间，所述液晶层包括多个二色性染料液晶微滴104，相比传统的显示面板，该显示面板中的液晶层包括多个二色性染料液晶微滴104，其中，二色性染料液晶微滴104中的二色性染料可以更有效吸收入射光线，使得当显示面板在无信号传输时，所述二色性染料聚合物网络液晶可以更好的吸收入射光线，因此降低了显示面板的暗态透过率，从而提高显示面板的对比度、改善其光学性能。
如图1和图2所示，图2为本发明实施例提供一种显示面板在提供信号传输时的状态的一个实施例结构示意图，具体的，二色性染料液晶微滴包括液晶材料201和二色性软料分子202，当显示面板在提供信号传输时的状态，所述二色性染料分子202将随液晶材料201偏转，所述二色性染料分子202的吸光轴与寻常光的偏振方向相垂直，此时所述二色性染料分子对光的吸收变弱，因此其对显示面板的亮态透过率就影响不大。
本发明显示面板通过采用如上实施例中描述的二色性染料聚合物网络液晶，是藉由添加二色性染料分子及其可随液晶材料转动的特点，去增加聚合性网络液晶的光吸收特性，用以改善暗态不够暗的问题，进一步增进显示面板的对比度。
其中，所述显示面板可以为透明的显示面板，本发明实施例中可以提供一透明的显示面板，由于将所述二色性染料和所述液晶材料一同被包裹在聚合物网络中，使得当显示面板在无信号传输时，二色性染料聚合物网络液晶可以更好的吸收入射光线，因此降低了显示面板的暗态透过率，从而提高显示面板的对比度、改善其光学性能。
在上述实施例的基础上，在本申请的另一个具体实施例中，所述二色性染料液晶微滴104包含二色性染料、液晶材料和包含多个聚合物网络。
其中，为了更好的使二色性染料和液晶材料的相互融合，当添加了有机溶剂，可以有效的使二色性染料均匀分布于混合液中，本法发明实施例并不对所述有机溶剂作限定，具体根据实际情况而定。例如，所述有机溶剂可以是苯乙烯、全氯乙烯、三氯乙烯、乙烯乙二醇醚和三乙醇胺。
具体的，可在容器中采用质量百分比为96.5%的所述液晶材料和质量百分比为2.5%的所述二色性染料进行混合，并可将容器进行震动使得所述液晶材料和所述二色性染料进行充分混合。
一般而言，聚合物网络液晶（Polymer Network Liquid Crystal，PNLC）的应用正被持续研究中，其在无施加电压的状态下，液晶材料中的液晶材料的轴向为任意方向的散乱状，入射光于进入聚合性网络液晶层后便会产生不同方向的折射光因而出现光散射现象，并使屏幕呈现不透明状态；而当施加电压时，该液晶材料的轴向便会顺着电场的方向进行规则性的排列，入射光于进入聚合物网络液晶层后便可顺着已规则性排列的液晶材料前进，并穿透该聚合物网络液晶层，故使屏幕呈现透明状态。在本发明实施例中，通过采用所述聚合物网络液晶将所述二色性染料和所述液晶材料一同包裹早所述聚合物网络中，形成二色性染料聚合物网络液晶，使得当显示面板在无信号传输时，二色性染料聚合物网络液晶可以更好的吸收入射光线，因此降低了显示面板的暗态透过率，从而提高显示面板的对比度、改善其光学性能。
在上述实施例的基础上，在本申请的另一个具体实施例中，所述二色性染料为单一的黑色二色性染料或者呈现为黑色的多种二色性染料的混合体。
其中，所述二色性染料是不具备电极性的，因此是随着液晶材料的运动而运动的，且所述二色性染料用于吸收光，且二色性染料可见光吸收光谱介于400至780纳米之间。
在上述实施例的基础上，在本申请的另一个具体实施例中，所述二色性染料包括偶氮染料、蒽醌染料、及偶氮甲碱染料中的至少一种，例如所述二色性染料为偶氮染料和蒽醌染料的混合物。
在上述实施例的基础上，在本申请的一个具体实施例中，所述二色性染料液晶微滴104中，所述液晶材料的质量百分比为95.0～99.0％，例如，所述液晶材料的质量百分比可取96.5%。具体的，本发明对所述液晶材料的质量百分比的具体数值不作限定，具体视实际情况而定。
在上述实施例的基础上，在本申请的一个具体实施例中，所述二色性染料液晶微滴104中，所述二色性染料的质量百分比为0.1～5.0％，例如，所述二色性染料的质量百分比为2.5%。具体的，本发明对所述二色性染料的质量百分比的具体数值不作限定，具体视实际情况而定。
在上述实施例的基础上，在本申请的一个具体实施例中，所述二色性染料液晶微滴104中，所述聚合物网络的质量百分比为0.3～0.5％，例如，所述聚合物网络的质量百分比为0.38%。具体的，本发明对所述聚合物网络的质量百分比的具体数值不作限定，具体视实际情况而定。
