Description
技术领域
本发明涉及显示电子产品技术领域，具体地，涉及一种电子纸产品的制备方法。
背景技术
显示技术在日常生活的广泛应用，从而受到持续的关注和研究。目前大量使用的液晶显示器(LCD)、发光二极管(LED)不是柔性的，如果环境光很强，显示效果不够理想。目前，无背光、柔性显示、低功耗是显示器的研究热点。尽管电致发光二极管(OLED)是柔性显示器，但OLED使用寿命非常短，且难以实现大尺寸显示。
多像素柔性聚合物分散型液晶(PDLC)是柔性透明显示的首选，只需要背板为图像提供覆盖，使读者能够看到面板背部的光。它不需要背光板，可为读者提供类似于阅读纸质书籍的体验。
制备的电子纸产品可以弯曲，显示面积较大，分辨率为128×128，像素尺寸小，为0.5mm×0.5mm。
发明内容
本发明的目的是提供一种电子纸产品的制备方法，以解决传统电子纸产品无法满足大尺寸显示和高分辨率的要求。制备的方法包括以下步骤：
步骤A：将正性晶体液晶E7与紫外固化胶混合，并加入亚纳米级ITO粉末使用超声波搅拌和磁力搅拌使混合物充分均匀混合。
步骤B：将所述混合物旋涂在PET-ITO基底上。
步骤C：另一图形化电极的PET-ITO基板覆盖在所述涂有混合物一面的基底上。
步骤D：使用100W的水银点光源灯对所述PDLC显示器件进行固化。
步骤E：使用银涂料将图形化的电极和金丝连接。
本发明的一个实施例中，所述正性晶体液晶E7，具有no＝1.519，ne＝1.737，Δn＝0.218的参数。
本发明的一个实施例中，ITO粉末具有亚微米级。
本发明的一个实施例中，正性晶体液晶E7与紫外固化胶均匀混合。
本发明的一个实施例中，使用ITO粉末加入混合物中，并均匀搅拌。
本发明的一个实施例中，使用橡胶滴管把混合物旋涂在PET-ITO基底上。
本发明的一个实施例中，混合物旋涂时的转速为1500转/分钟，旋涂时长30秒。
本发明的一个实施例中，使用水银点光源灯照射器件，灯距离器件的距离为6英寸，固化时长为5分钟。
本发明的电子纸制备方法具有以下优点：
本发明制备的电子纸所形成的聚合物网络分离的液滴均匀，像素尺寸小，达到0.5mm×0.5mm。厚度约10μm，最大透光率接近80％。本发明制备的电子纸提高了显示器件的成像面积。
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，下面将对实施例或现有技术描述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的前提下，还可以根据这些附图获得其他的附图。
图1是本发明的方法制备的电子纸的横截面电镜图；
图2是本发明电子纸的显示效果。
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。
步骤A：将正性晶体液晶E7(no＝1.519，ne＝1.737，Δn＝0.218)与紫外固化胶混合，并加入亚纳米级ITO粉末使用超声波搅拌和磁力搅拌使混合物充分均匀混合。
步骤B：将所述混合物旋涂在PET-ITO基底上。
步骤C：另一图形化电极的PET-ITO基板覆盖在所述涂有混合物一面的基底上。
