本发明涉及显示器件领域，尤其是一种电泳显示膜片和电泳显示器。

附图说明
图1至3为本发明提供的三个实施例的电泳显示器的结构示意图。
图4至6为本发明提供的三个实施例的电泳显示膜片的结构示意图。
具体实施方式
下面结合附图和具体实施例对本发明所述技术方案作进一步的详细描述，以使本领域的技术人员可以更好的理解本发明并能予以实施，但所举实施例不作为对本发明的限定。
请参考图1至图3，本发明实施例提供一种电泳显示器，其包括透明基板13、透明导电电极12、电泳显示层20和驱动底板30，透明基板13、透明导电电极12、电泳显示层20和驱动底板30依次层叠连接，电泳显示层20包括 多个显示微单元21，每个显示微单元21包括电泳液及悬浮于电泳液中的电泳粒子。驱动底板30上设置有驱动电路及与驱动电路连接的驱动电极，驱动电极和透明导电电极12用于在电泳显示层20的两端施加电信号。电泳显示层20与透明导电电极12之间和/或电泳显示层20与驱动底板30之间通过胶黏层11连接，电泳显示层20的厚度与胶黏层11的厚度之比为1-10:1。
具体来说，透明基板13可以由聚对苯二甲酸乙二醇酯(PET)、聚乙烯(PE)、聚酰亚胺(PI)、聚萘二甲酸乙二醇酯(PEN)等材料制成。透明导电电极12可以通过在透明基板13上生长氧化铟锡(ITO)薄膜、纳米银线或者石墨烯薄膜等材料制成。显示微单元21中的电泳粒子可以有黑色粒子和白色粒子或者其他色的粒子，电泳粒子带有电荷，可以在电场作用下在电泳液中移动，通过不同电信号控制不同颜色粒子向透明导电电极12移动，使得电泳显示层20显示图案和文字。在一些实施例中，电泳显示层20可以通过在透明导电电极12上涂布电子墨水，电子墨水含有多个具有微胶囊结构的显示微单元21，然后将电子墨水烘干，形成电泳显示层20。电子墨水的成分和制造方法可以参考中国专利申请CN106292118A中的相关描述。在另一些实施例中，显示微单元21具有微杯结构，相应的电泳显示层20的具体结构、材料和制造方法可以参考中国专利CN1246730C中的相关描述。显示微单元21的粒径可以在几微米至几百微米之间。驱动底板30可以通过在玻璃、PI、PET等衬底上用半导体制程制作薄膜晶体管(Thin Film Transistor，TFT)驱动电路而形成。驱动底板30和透明导电电极12均连接电路，用于在电泳显示层20的两侧施加电信号。驱动电极可以是电泳显示器的像素电极，通过控制器控制驱动电极上的电压信号，来控制电泳显示层20显示显示图案和文字。
可以在电泳显示层20的表面上涂布胶黏剂，胶黏剂固化后形成胶黏层11。胶黏层20具有一定的导电性。如果胶黏层11太厚，会降低透明导电电极12和驱动底板30施加到电泳显示层20的电压。当胶黏层11设置在透明导电电极12和电泳显示层20之间时，胶黏层11是透明的，太厚的胶黏层11会影响到电泳显示层20到电泳显示器表面的透光性，从而影响电泳显示器的光学 特性。如果胶黏层11太薄，则会影响电泳显示层20与透明导电电极12或者驱动底板30之间的连接强度，使得电泳显示器在遭受机械冲击时，容易损坏。因此将电泳显示层20的厚度与胶黏层11的厚度之比控制为1-10:1，可以使电泳显示器既具有较好的电光显示性能，又具有较好的机械强度。一般来说，电泳显示层20的厚度在20微米-150微米之间，胶黏层11的厚度一般在15微米-20微米之间。
请参考图1，在优选实施例中，透明导电电极12与电泳显示层20之间通过胶黏层11连接，电泳显示层20包括胶黏剂，多个显示微单元21被胶黏剂所包覆，胶黏剂与驱动底板30粘接。制造时，可以先在透明基板13上形成透明导电电极12，将电泳显示层20与驱动底板30连接，然后在透明基板13的内侧表面上涂布胶黏剂，将电泳显示层20层压到胶黏剂上，胶黏剂被烘干固化后，形成胶黏层11。在驱动底板30上制作电泳显示层20时，可以在电子墨水中加入胶黏剂，电子墨水固化后形成电泳显示层20，胶黏剂与驱动底板30粘接，从而使电泳显示层20固定在驱动底板30上。固化后，多个显示微单元21之间的填充物中含有胶黏剂。
请参考图2，在另一优选实施例中，驱动底板30与电泳显示层20之间通过胶黏层11连接，电泳显示层20包括胶黏剂，多个显示微单元21被胶黏剂所包覆，胶黏剂与透明导电电极12粘接。制造时，可以先在透明基板13上形成透明导电电极12，然后在透明导电电极12的内侧表面上涂布电子墨水，将电子墨水烘干固化后，形成电泳显示层20。然后在驱动底板30的上表面上涂布胶黏剂，将由电泳显示层20、透明导电电极12和透明基板13构成的电泳显示膜片层压到胶黏剂上，电泳显示层20与胶黏剂粘接，胶黏剂被烘干固化后，形成胶黏层11。在该实施例中，胶黏层11可以是不透明的，但仍需要具有一定的导电性。与上述实施例类似，电子墨水中含有胶黏剂，电子墨水固化后，胶黏剂与透明导电电极12粘接，从而使电泳显示层20固定在透明导电电极12上。固化后，多个显示微单元21之间的填充物中含有胶黏剂。
请参考图3，电泳显示层20与透明导电电极12之间和电泳显示层20与 驱动底板30之间均通过胶黏层11连接。该电泳显示器的制备工艺与上述两个实施例类似，此处不再赘述。
在优选实施例中，显示微单元21具有微胶囊结构或微杯结构。微胶囊结构可以参考中国专利申请CN103091926A中的相关描述，微杯结构可以参考中国专利CN1246730C中的相关描述，此处不再赘述。
在优选实施例中，透明导电电极12包括ITO薄膜、纳米银线或者石墨烯薄膜，也即透明导电电极12通过ITO薄膜、纳米银线或者石墨烯薄膜进行导电。
请参考图4至图6，提供一种电泳显示膜片，其包括电泳显示层20及与电泳显示层20层叠连接的胶黏层11。电泳显示层20包括多个显示微单元21，每个显示微单元21包括电泳液及悬浮于电泳液中的电泳粒子，电泳粒子可以有黑色粒子和白色粒子或者其他色的粒子，电泳粒子带有电荷，可以在电场作用下在电泳液中移动，通过不同电信号控制不同颜色粒子向透明导电电极12移动，使得电泳显示层20显示图案和文字。可以在电泳显示层20的表面上涂布胶黏剂，胶黏剂固化后形成胶黏层11。电泳显示层20的厚度t2与胶黏层11的厚度t1之比为1-10:1。该电泳显示膜片可作为制造上述实施例中的电泳显示器的一个中间组件。胶黏层11的外侧还可以贴有离型膜，以便于电泳显示膜片的运输。电泳显示层20的结构和制作工艺与上述实施例类似，此处不再赘述。
请参考图4，电泳显示层20的两侧均设置有胶黏层11，电泳显示层20的厚度与每个胶黏层11的厚度之比均为1-10:1。两个胶黏层11的外侧均可贴有离型膜，以便于电泳显示膜片的运输。制作电泳显示器的过程中要使用电泳显示膜片时，撕掉离型膜，然后将电泳显示膜片与透明导电电极12和/或驱动底板30粘接即可。图5所示的电泳显示膜片的实施例，与图4所示实施例不同之处在于，胶黏层11仅设置于电泳显示层20的上侧，在图6所示的实施例中，胶黏层11则设置于电泳显示层20的下侧。
本发明实施例提供的电泳显示模组及电泳显示器，通过将电泳显示层的 厚度与胶黏层的厚度控制在一个适当的比例范围内，使得电泳显示器具有较好的电光显示性能和机械强度。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
