附图说明

具体实施方式
请参考图1，电子纸10包括下基板20、电泳层30和上基板40。电泳层30置于下基板20和上基板40之间。在本实施方式中，该电子纸装置10为反射式电泳显示装置。
下基板20包括基体21和设置于基体21上的若干个薄膜晶体管(TFT，Thin-FilmTransistor)22以及与该薄膜晶体管22一一对应的像素电极23。基体21可为玻璃基板、塑料基板、电路板或柔性电路板。
上基板40包括多个透明电极42，该透明电极42可为铟锡氧化物、铝锌氧化物或镉锡氧化物，透明电极42与像素电极23也呈一一对应关系。
电泳层30包括若干平行的管状容置腔302，管状容置腔302的轴线与上基板40以及下基板20的平面垂直。每个管状容置腔302均位于一个像素电极23以及透明电极42之间并与之分别电连接，每一像素电极23均位于一管状容置腔302以及一薄膜晶体管22之间并分别与之电连接。该管状容置腔302容置有介电溶液(dielectric solution)304和若干有色粒子306。有色粒子306分散于介电溶液304中，并且带有正电荷或负电荷。
请同时参考图2，在本实施方式中，该电泳层30中的该若干管状容置腔302以矩阵式排列，但并不以此为限。管状容置腔302的数量可根据对电子纸10的分辨率的要求确定。每三个管状容置腔302以RGB阵列形式构成一像素单元308，构成一像素单元308的三个管状容置腔302中的有色粒子306的颜色分别为红色(R)、蓝色(B)和绿色(G)。为了便于说明，具有红色、蓝色和绿色的有色粒子323的管状容置腔分别被标号为302r、302b和302g。
在像素单元308中，管状容置腔302r、管状容置腔302b和管状容置腔302g的排列方式没有限制，例如，在图2中，位于左上角的像素单元308中，从左到右为管状容置腔302r、管状容置腔302g和管状容置腔302b，而位于右下角的像素单元308中，从左到右为管状容置腔302b、管状容置腔302r和管状容置腔302g。
在本实施方式中，所有薄膜晶体管22均包括一控制端、一第一导通端以及第二导通端，该薄膜晶体管22的控制端均连接至一门驱动单元50，第一导通端均连接至一电源驱动单元60，每一薄膜晶体管的第二导通端分别连接至对应的像素电极23。该电源驱动单元60还与该透明电极42均连接。
当某一薄膜晶体管22受该门驱动单元50的控制而导通时，该对应的像素电极23通过该导通的薄膜晶体管22与该电源驱动单元60电连接。电源驱动单元60输出一电压从而使得该像素电极23与该透明电极42产生一电势差，从而引起该管状容置腔302中的有色粒子306移动而可显示对应的颜色。例如，在一个像素单元308中，若只有管状容置腔302r对应的薄膜晶体管22导通，则该像素单元308显示红色，若只有管状容置腔302g对应的薄膜晶体管22导通，则该像素单元308显示绿色，若管状容置腔302r以及管状容置腔302g对应的薄膜晶体管22导通，则该像素单元308显示红色与绿色的混色，即显示黄色。
而该电源驱动单元60根据视频信号的不同，对不同的薄膜晶体管22所对应的像素电极23输出的电压值不同，使得该薄膜晶体管22所对应的像素电极23以及透明电极42之间的电势差不同，而由于管状容置腔302分别与该像素电极23以及透明电极42电连接，则该薄膜晶体管22所对应的像素电极23以及透明电极42之间的电势差即为该薄膜晶体管22对应的管状容置腔302两端的电势差。同样以一个像素单元308为例，若对同一个像素单元中管状容置腔302所对应的薄膜晶体管22所输出的电压差V1、V2和V3相同，则同一个像素单元中的三个管状容置腔302大致相同数量的红色、蓝色和绿色的有色粒子306移动至上基板40的附近，根据三原色原理，与像素单元308对应的区域显示为白色。根据该输出至薄膜晶体管的电压差V1、V2和V3大小的不同，可以控制该管状容置腔302中移动至上基板40的附近的红色、蓝色和绿色的有色粒子306的数量，而移动至上基板40的附近的有色粒子306数量不同，该管状容置腔302显示的颜色的深浅也不一样，从而一个像素单元308中的三个管状容置腔302混合出来的色彩也不一样。
从而，通过门控制器50控制选择薄膜晶体管22的导通截止，控制相应像素单元308是否显示颜色，而又根据电源驱动单元60对薄膜晶体管22输出不同的电压来控制该颜色的深浅，从而可在显示像素单元308对应的区域混合出各种颜色。
请一并参考图3，为本发明一实施方式中电子纸显示装置的模块架构图。该电子纸显示装置1包括该电子纸10、一显示接口11、一信号转换单元12、该门驱动单元50以及该电源驱动单元60。
其中，该显示接口11与该信号转换单元12连接，该信号转换单元12还分别与该门驱动单元50以及该电源驱动单元60连接，该电子纸10也分别与该门驱动单元50以及该电源驱动单元60连接。
该显示接口11用于接收从电脑主机等电子装置传送过来的视频信号。该信号转换单元12用于将该视频信号转换成控制信号。一般，从电脑主机等电子装置传送过来的视频信号包括视频显示信号以及时钟信号，在本实施方式中，该信号转换单元12用于将视频信号经过时序转换生成移位时钟信号后发送给门驱动单元50，将视频信号中的RGB信号经过数模转换后生成一模拟RGB信号后发送给电源驱动单元60，即在本实施方式中，该控制信号包括移位时钟信号以及模拟RGB信号。从而，该门驱动单元50根据该移位时钟信号控制相应的薄膜晶体管22的导通，而该电源驱动单元60根据该模拟RGB信号提供不同的电压至该薄膜晶体管22，使得与该电源驱动单元60连接的像素电极23以及透明电极42之间形成相应的电势差，使得对应的管状容置腔中的有色带电粒子移动而显示对应的颜色。如前所述，对应的像素单元308即可显示对应的颜色。在该门驱动单元50以及该电源驱动单元60的控制下，该电子纸即显示该视频信号所对应的图像。
