Description

一种彩色电子纸
技术领域
本发明涉及电子纸研究领域，特别是涉及一种彩色电子纸。
背景技术
电子纸(E-paper)是一种新型的显示材料，基于电泳原理的双稳态显示技术，用途广泛，具有超低能耗、薄如纸张、可以弯曲和类似书本的清晰度等优越性能，通过颜色的黑白、深浅变化来表现文字和图画，显示效果与真实的纸质书籍非常类似。目前电子纸显示屏广泛应用于电子阅读器(电子书)、电子价格牌，智能卡、手表、手机、工业仪器、仪表、动态显示广告牌以及媒介产品等领域。
单色电泳式电子纸从实验室走向产业化的成功催生了彩色电子纸的发展，以满足人们对反射式显示器的多样需求。然而，在成功实现彩色化之前，还有许多挑战性的问题仍待克服。
目前，彩色电子纸的制作方案包括：彩色滤光膜、横向驱动、多粒子体系以及微胶囊子像素方案。在上述几种方案里，添加彩色滤光膜于黑白电子纸上是最为成熟、适合于量产的方案。然而，通常彩色滤光膜透射光谱过宽，红绿蓝三色滤光膜透射光谱重叠较大，会导致电子纸显示色彩少、色彩饱和度低，影响其彩色显示色域。
发明内容
本发明的目的是提供一种彩色电子纸，能够扩大电子纸彩色显示区域和提高色彩饱和度。
为实现上述目的，本发明提供了如下方案：
一种彩色电子纸，所述彩色电子纸包括由上至下依次排列的第一封装层、彩色滤光层、粘合层、第二封装层、透明导电层、电泳显示层、微胶囊、驱动层和基板，所述彩色电子纸还包括光子晶体结构层，所述光子晶体结构层设置在所述彩色滤光层之下、所述电泳显示层之上的任意一层。
可选地，所述光子晶体结构层为一维光子晶体结构层。
可选地，所述一维光子晶体结构层为不同折射率的材料或者介质按照设定的顺序交替堆叠形成的多层结构，所述一维光子晶体结构层的折射率在一个方向上呈现固定的周期波动。
可选地，所述粘合层采用光学胶。
可选地，所述透明导电层由透明导电的材料制作而成。
可选地，所述电泳显示层为微胶囊式电泳显示层或微杯式电泳显示层。
可选地，所述微胶囊电泳显示层中包裹有透明的电泳液、带正电荷或负电荷的一种颜色的粒子以及中性的另一种颜色的粒子。
根据本发明提供的具体实施例，本发明公开了以下技术效果：
本发明引入光子晶体结构层，可有效地调控(窄化)滤光膜的透射光谱，降低透射光谱所对应的半波宽值，提升彩色电子纸显示屏色彩饱和度，扩大电子纸彩色显示色域。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为本发明彩色电子纸组成示意图；
图2为本发明一维光子晶体示意图；
图3为本发明不含光子晶体结构层和含光子晶体结构层对比示意图；
图4为本发明有无光子晶体结构时滤光膜透射光谱对比示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的目的是提供一种彩色电子纸，能够扩大电子纸彩色显示区域和提高色彩饱和度。
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
图1为本发明彩色电子纸组成示意图。如图1所示，一种彩色电子纸包括由上至下依次排列的第一封装层1、彩色滤光层2、粘合层4、第二封装层5、透明导电层6、电泳显示层7、微胶囊8、驱动层9和基板10，所述彩色电子纸还包括光子晶体结构层3，所述光子晶体结构层3设置在所述彩色滤光层2之下、所述电泳显示层7之上的任意一层。
所述光子晶体结构层3为一维光子晶体((1DPCs))结构层。图2为本发明一维光子晶体示意图。所述一维光子晶体结构层为不同折射率的材料或者介质按照设定的顺序交替堆叠形成的多层结构，所述一维光子晶体结构层的折射率在一个方向上呈现固定的周期波动。针对不同颜色的滤光膜，所述光子晶体结构层3的结构设计和材料不同。当前，主流的低折射率材料主要有SiO2、LiF等，高折射率材料主要选择TiO2、WO3等。一些聚合物，如聚苯乙烯、聚甲基丙烯酸甲酯等，被应用于制作柔性1DPCs。
对于最简单的(A/B)N型1DPCs(A、B为组成1DPCs的两种不同折射率的材料，N为周期数)，1DPCs的光学周期d与其光子禁带的中心波长λ0有关：
Figure BDA0003032762990000031
其中，nA和nB为A、B两种材料的折射率；dA和dB为A、B两种材料的厚度；λ0为光子禁带的中心波长；X为可调参数，计算时一般取1。
为实现对于1DPCs的光子禁带的可调控性，在设计时一般针对特定λ0转求dA和dB。通常取nAdA＝nBdB，采用公式(2)可确定dA和dB：
Figure BDA0003032762990000032
其中，ω0为光子禁带的中心频率；c为光速。
所述粘合层4采用光学胶等粘胶剂。所述透明导电层6由透明导电的材料制作而成。所述电泳显示层7为微胶囊式电泳显示层或微杯式电泳显示层等反射型显示模组。以微胶囊电泳显示层为例，所述微胶囊电泳显示层中包裹有透明的电泳液、带正电荷或负电荷的一种颜色的粒子以及中性的另一种颜色的粒子。在驱动层9和透明导电层6之间施加的驱动电压驱动下，带电的颜料粒子在微胶囊8中移动进行显示。当然在其他实施例中，所述微胶囊电泳显示层中包裹有透明的电泳液、带正电荷的一种颜色的粒子和带负电荷的另一种颜色的粒子，在驱动电压的驱动下，带电的粒子在微胶囊8中移动进行显示。以红色滤光层为例，没有光子晶体结构时透射光光谱较宽，加上光子晶体后光谱会变窄，降低透射光谱所对应的半波宽值，提升颜色饱和度，最终与其他光谱窄化的绿色和蓝色滤光层共同作用提升电子纸彩色显示色域。图3为本发明不含光子晶体结构层和含光子晶体结构层对比示意图；图4为本发明有无光子晶体结构时滤光膜透射光谱对比示意图。如图4所示，光谱变窄，所以降低了半波宽。色彩的饱和度色彩的鲜艳程度，也称作纯度。纯度越高，表现越鲜明，纯度较低，表现则较黯淡。半波宽降低，光谱变窄，饱和度提升。红绿蓝三原色的饱和度的提升，可以扩大显示色域。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处。综上所述，本说明书内容不应理解为对本发明的限制。
