Description

显示面板及其制作方法与显示装置
技术领域
本发明涉及显示领域，尤其涉及一种显示面板及其制作方法与显示装置。
背景技术
现有的有源显示面板，广泛应用的为液晶面板。然而在采用液晶的偏转实现光线透光率的控制时，面板结构与制作工艺均较为复杂，具体的如下：
第一：液晶面板需要通过上下偏光板实现光线的偏振输入、输出，否则无法显示正常，结构复杂、制作工艺多（如需要进行偏光板贴附等工艺）且成本高；且通过偏光板使得光源的有效利用率降低了；
第二：需要使整个面板的液晶偏转实现一致性，需要再设置配向膜，在液晶层内还需设置隔垫物等部件，再次复杂了结构和制作工艺，提高了制作成本；
第三：液晶面板还存在视角问题，虽然现在的液晶面板可以通过如IPS（In Plane Switching，面内转换）技术或ADSDS（ADvanced SuperDimension Switch，简称ADS，高级超维场转换）技术解决上述问题，可再次提高了制作成本，复杂了制作工艺；
其中，高级超维场转换技术为：通过同一平面内狭缝电极边缘所产生的电场以及狭缝电极层与板状电极层间产生的电场形成多维电场，使液晶盒内狭缝电极间、电极正上方所有取向液晶分子都能够产生旋转，从而提高了液晶工作效率并增大了透光效率。高级超维场转换技术可以提高TFT-LCD产品的画面品质，具有高分辨率、高透过率、低功耗、宽视角、高开口率、低色差、无挤压水波纹（push Mura）等优点；
第四：由于液晶分子的化学特性，在生产过程中以及旧产品的报废过程中存在着化学污染，不利于环保。
发明内容
（一）发明目的
针对上述问题，本发明旨在提供一种结构简单、制作工艺简便、制作成本低且环保的显示面板及其制作方法与显示装置。
（二）技术方案
为达上述目的，本发明提供了一种显示面板，包括上透明基板与下透明基板；还包括位于上透明基板和下透明基板之间的黑矩阵；
所述黑矩阵与所述上透明基板以及所述下透明基板组合形成若干相互隔离的像素空间；
所述像素空间内设有电致变色材料；
所述上透明基板与下透明基板分别设有电极，位于所述上透明基板与所述下透明基板的所述电极组合后用于在每个像素空间形成独立的电场。
具体地，所述电极包括第一电极与第二电极；
所述第一电极分布在每一像素空间所在处的上透明基板上；
所述第二电极分布在每一像素空间所在处的下透明基板上；
其中，改变所述第一电极与第二电极之间的压差，则所述电致变色材料的光透过率改变。
具体地，所述电极包括位于不同基板上的第一电极以及第二电极；
所述第一电极为公共电极，覆盖所述上透明基板或所述下透明基板的显示区域；
所述第二电极分布在每一像素空间所在处的下透明基板或上透明基板上。
优选地，所述上透明基板或所述下透明基板上按像素间隔分布有不同颜色的彩色光阻图形。
优选地，所述电致变色材料为有机电致变色材料、无机电致变色材料或复合电致变色材料。
为达上述目的，本发明提供了一种显示装置，包括如上所述的显示面板。
尤其是，还包括背光源；所述显示面板设置在所述背光源的出光侧。
为达上述目的，本发明还提供了一种显示面板的制作方法，包括以下步骤：

进一步地，所述步骤2与所述步骤3之间还包括在上透明基板或下透明基板上按像素间隔设置不同颜色的彩色光阻图形的步骤M。
进一步地，所述步骤3采用滴注或喷墨工艺添加电致变色材料。
（三）本发明显示面板及其制作方法与显示装置的有益效果
第一：本发明提供的显示面板，由于是通过电致变色材料在电流作用下的氧化还原反应而对光线产生不同的程度的透射和反射性来控制光透过率，呈现多灰阶，故相对于传统的液晶显示面板无需上下偏光板实现光线路径改变来控制灰度的呈现，具有结构简单的优点，由此同时省略了偏光板贴附等步骤，制作简便，制作成本低；于此同时对光源的亮度的要求降低了；
第二：本发明提供的显示面板，由于采用电致变色材料进行多灰阶的呈现，电致变色材料是密封在每一个像素空间内的，无需配向膜控制液晶的偏转方向，同时黑矩阵起到了支撑上下透明基板的目的，无需隔垫物进行支撑，再次简化了结构和制作工艺；
第三：本发明提供的显示面板，不存在视角问题，从而具有显示效果佳的优点；
第四：本发明提供的显示面板，采用的是电致变色材料实现多灰阶的呈现，而相对于有毒性的液晶，具有污染小与绿色环保的优点。
综合上述，本发明的显示面板、显示装置、由本发明制作方法制作的显示面板，具有结构简单、制作工艺简便、显示效果佳且成本低等多重优点。
附图说明
图1为本发明实施例一所述的显示面板的侧视结构示意图；
图2为本发明实施例三所述的显示装置的侧视结构示意图；
图3为本发明实施例四所述的显示面板的制作方法流程图。
具体实施方式
下面结合说明书附图以及实施例对本发明显示面板及其制作方法与显示装置做进一步的说明。
实施例一：
如图1所示，本实施例的显示面板，包括上透明基板2、下透明基板1以及设置在所述上透明基板与下透明基板之间的黑矩阵3；
所述黑矩阵3与上透明基板2以及下透明基板1组合形成若干相互隔离的像素空间；黑矩阵在传统的液晶面板当中也有设置，主要是应用于不同颜色的彩色光阻图形之间的遮光条，用于遮住栅线和/或数据线，而本实施例中所述的黑矩阵，不仅用作不同颜色的彩色光阻图形之间的遮光条，同时其高度等于上、下透明基板之间的距离，既起到围成一个封闭隔离的像素空间，同时起到支撑上、下透明基板的作用，一个部件实现了多重功能，具有结构简单紧凑巧妙的优点；
所述像素空间内设有电致变色材料4；所述电致变色材料（Electrochromic）在电场的作用下，发生氧化还原反应从而改变对光的透射率和反射率，从而改变光线输出的亮度，从而可以用于在不同电压控制下，呈现不同的灰阶，如0-255灰阶，从而可用于取代传统的液晶用于显示；
所述上透明基板与下透明基板分别设有电极，位于所述上透明基板与所述下透明基板的所述电极组合后用于在每个像素空间形成独立的电场。
在本实施例中改变位于所述上透明基板与所述下透明基板的电极之间的电压差，通过改变电致变色材料两端的电压达到了改变像素光透过率，形成不同灰阶的目的。
位于所述上透明基板与所述下透明基板的电极组合用于独立控制每一像素的电压差，有多种实现方式，以下是两种优选方式：
第一种：所述电极包括第一电极与第二电极，其中，
所述上透明基板2在每一所述像素空间所在处均设有第一电极；
所述下透明基板1在每一所述像素空间所在处均设有第二电极；
所述上透明基板2与所述下透明基板1上的电极可为同材质、同结构的透明电极，如ITO（氧化铟锡）、IZO（氧化铟锌）等；电极按像素的设置以矩阵形式分布在基板上，通过驱动电路使得扫描周期内，不同像素所对应的第一电极与所述第二电极之间的电压差不同，从而在电致变色材料的作用下，光透过率不同，从而显示出不同的灰阶，从而呈现出要显示的图像；第一电极与第二电极所对应的为与像素数目相等的电极矩阵；每一像素对应一个第一电极与一个第二电极；
第二种：所述电极包括位于不同基板上的第一电极以及第二电极，其中：
第一电极为公共电极，由整个覆盖在上透明基板或下透明基板显示区域的单个电极构成；
第二电极的个数与像素个数相等且对应于每一像素空间，分布在未设有所述公共电极的下透明基板上或上透明基板上；在具体工作时，向公共电极提供一个公共电压，再分别通过向各像素所对应的第二电极提供不同的电压，实现各像素的所对应的压差的独立控制；从而实现分别控制每一像素空间内的电致变色材料，从而控制每一像素所呈现的灰阶。
作为本实施例的进一步的改进，为了呈现出彩色图像，采用多种不同颜色的彩色光阻图形配合使用，在光混合的作用下，显示出彩色图像；在显示面板中，通常情况下，采用R/G/B（红/绿/蓝）三种颜色的光阻图形配合使用，所述R/G/B三色光阻图形可以是按像素间隔分布在所述上透明基板2的下表面或所述下透明基板1的上表面。需要说明的是，根据生产或设计的需要，除了使用R/G/B三种颜色外，还可以采用其他颜色的光阻图形，例如透明色、黄色等，在此不做限定。
如图1所述，以R/G/B三种颜色光阻图形设置于上透明基板的情况为例，红色光阻图形51、绿色光阻图形52以及蓝色光阻图形53分布在上透明基板2的下表面，且按像素间隔分布。
所述电致变色材料4的氧化还原反应是可逆反应，故而应用于像素的刷新，形成不同图像，此外电致变色材料不存在液晶分子所谓的长轴、短轴的显示视角问题，故而由其所制作的显示面板不存在视角问题，故而显示效果佳，无需为增大观看视角而增加部件和流程工艺，故而显示效果佳的同时，制作成本低。此外电致变色材料4相对于有毒性的液晶分子，具有化学污染小、绿色环保等多重优点。
综合上述，本实施例所述的显示面板，具有结构简单、巧妙、制作成本低、显示效果好等多重优点。
实施例二：

所述黑矩阵与上、下透明基板组合形成若干相互隔离的像素空间；
所述像素空间内设有电致变色材料；
所述上透明基板与下透明基板分别设有电极，位于所述上透明基板与所述下透明基板的所述电极组合后用于在每个像素空间形成独立的电场。
其中，改变位于所述上透明基板与所述下透明基板的电极之间的压差，则所述电致变色材料的光透过率改变；
所述上透明基板的下表面或所述下透明基板的上表面按像素间隔分布有R/G/B彩色光阻图形；需要说明的是，根据生产或设计的需要，除了使用R/G/B三种颜色外，还可以采用其他颜色的光阻图形，例如透明色、黄色等，在此不做限定。
所述电致变色材料为有机电致变色材料、无机电致变色材料或复合电致变色材料。
所述有机电致变色材料包括聚噻吩类及其衍生物、紫罗精类、四硫富瓦烯、金属酞菁类化合物以及聚苯胺类等中的一种或多种；
所述无机电致变色材料包括WO3，MoO3以及V2O5中的一种或多种；WO3为三氧化钨、MoO3为三氧化钼、V2O5为五氧化二钒。
所述复合电致变色材料，则是既包括了无机电致变色材料又包括了有机电致变色材料的复合材料。
所述电致变色材料具有取材广、取材简便的优点，故而进一步的简化了生产步骤。
实施例三：
本实施例的显示装置，包括如上述实施例一或实施例二任意所述的显示面板。所述显示装置可以为：手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。采用本发明所述的显示装置具有结构简单、制作简便、成本低、经济效益好且显示效果佳的优点。
本发明所述的显示面板，应用在有源显示装置中，故本实施例所述的显示装置还包括背光源，所述显示面板设置在所述背光源的出光侧。
具体的如图2所示，本实施例的显示装置包括背光源11以及本发明所述显示面板；在图2中的显示面板，包括上透明基板2、下透明基板1、黑色矩阵3、位于黑色矩阵3以及上透明基板2、下透明基板1依次环绕形成的隔离密封的像素空间内的电致变色材料4。红色光阻图形51、绿色光阻图形52以及蓝色光阻图形53，在具体的设置过程中，所述彩色光阻图形还可设置在下透明基板1上。
本实施例所述的显示装置，区别于传统的有源显示装置，采用了以可逆的氧化还原反应控制光线透过率显示图像的电致变色材料来呈现多重灰阶，具有结构简单、使用简便，且生产工艺简便、制作成本低，显示效果佳等多重优点。
实施例四：
如图3所示，本实施例显示面板的制作方法，包括以下步骤：
步骤1：分别制作上透明基板、下透明基板，并在上透明基板上设置第一电极、下透明基板上设置第二电极；
其中，上、下透明基板可以采用玻璃、石英、透明塑料等，上、下透明基板使用现有技术常规成熟的方法制备即可；所述第一电极以及所述第二电极均可以是透明导电材料，例如ITO（氧化铟锡）、IZO（氧化铟锌）等，在上、下透明基板上形成第一、二电极可以采用现有技术常规成熟的工艺，若为一整层无图案结构，可以直接采用沉积、涂覆、溅射等方式形成电极层即可，若为图案化结构，可以采用构图工艺（构图工艺通常包括光刻胶涂覆、曝光、显影、刻蚀、光刻胶剥离等工艺）形成要求的图案；
步骤2：在上透明基板的下表面或下透明基板的上表面设置黑矩阵；
通常，黑矩阵采用铬金属或黑色感光树脂材料形成；如果采用黑色感光树脂材料，直接进行曝光、显影工艺即可形成黑矩阵图案，如果采用铬金属，在采用沉积、涂覆、溅射等方式形成铬金属层后，再通过构图工艺形成黑矩阵图案。
步骤3：向设置有黑矩阵的基板上添加电致变色材料；
黑矩阵与设置于其上的基板形成了一侧开口的像素空间，所述电致变色材料通过所述开口添加，优选的本实施例还提供了两种添加所述电致变色材料的方法，
第一种为通过ODF（One Drop Filling，滴注）工艺将液态的电致变色材料滴入每一像素空间内；
第二种为通过喷墨（Inkjet）工艺将所述电致变色材料添加到每一像素空间内；
步骤4：将上透明基板与下透明基板真空对盒；
将上透明基板与下透明基板在真空条件下进行对盒，使得电致变色材料密封于像素空间内，形成固定封装的显示面板。
通过上述步骤实现了像素空间的密封和隔离，制得本发明所示的显示面板。通过向第一电极和/或第二电极施加电压，从而使得第一电极与第二电极之间产生电压差，在电致变色材料的导通下，形成电流通路；所述电致变色材料在通过得失电子，发生可逆的氧化还原反应，从而改变电致变色材料本身的组成成分，从而发生不同的透射和反射效果，形成不同的灰阶，相对于传统的通过液晶分子的旋转特性改变光线传的方向，在偏光板的过滤下形成不同灰阶的显示面板，具有无偏光板、无隔垫物、无配向膜等多重部件，结构简单，从而制作简单方便，步骤少，且制作出的产品本身显示效果佳。
实施例五：
本实施例的显示面板的制作方法，依次包括以下步骤：
步骤1：分别制作上透明基板、下透明基板，并在上透明基板上设置第一电极、下透明基板上设置第二电极；
步骤2：在上透明基板的下表面或下透明基板的上表面设置黑矩阵；
步骤M：在上透明基板或下透明基板上按像素依次间隔设置不同颜色的彩色光阻图形；
步骤3：采用ODF工艺或Inkjet工艺向设置有黑矩阵的基板上添加电致变色材料；
步骤4：将上透明基板与下透明基板真空对盒。
其中，步骤1-4与实施例四相同，在此不再赘述。
本实施例与实施例四的区别在于，所述步骤2与步骤3之间还包括的步骤M。通过不同颜色的彩色光阻图形的设置可以实现彩色显示，不同颜色的彩色光阻图形若位于所述上透明基板则设置在所述上透明基板的下表面，且不同颜色的彩色光阻图形间隔分布，若位于所述下透明基板上则设置在所述下透明基板的上表面，且按像素间隔分布。按像素间隔分布，即一个像素对应一种颜色，通过不同颜色的彩色光阻图形的滤过作用在光的混合作用下形成所需的彩色图像。
在显示面板中，通常情况下，采用R/G/B（红/绿/蓝）三种颜色的光阻图形配合使用。需要说明的是，根据生产或设计的需要，除了使用R/G/B三种颜色外，还可以采用其他颜色的光阻图形，例如透明色、黄色等，在此不做限定。
形成彩色光阻图形的方法可以采用现有技术常规成熟的方法，通过沉积、涂覆、溅射等方式形成彩色光阻涂层之后，采用曝光、显影等工艺形成彩色光阻图形。
作为本实施例的进一步的改进，所述步骤M与所述步骤3之间还设有步骤N：
所述步骤N：制作所述不同颜色的彩色光阻图形的保护层。通过保护层的设置，可以有效的保护彩色光阻图形，延长彩色光阻图形的寿命，以保证显示面板长时间的优良显示效果。
其中，保护层可以通过沉积、涂覆、溅射等方式在设置有彩色光阻图形的整个基板上形成。
本实施例所述的显示面板的制作方法，相对于传统的液晶面板的制作方法，具有制作步骤简单、步骤少，制作工艺简便，从而具有成本低，经济效果高、生产效率高等优点。
以上实施方式仅用于说明本发明，而并非对本发明的限制，有关技术领域的普通技术人员，在不脱离本发明的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本发明的范畴，本发明的专利保护范围应由权利要求限定。
