3)微胶囊和微杯结构制备过程过于复杂，造成生产制造上的困难和浪费，造成良率下降，材料浪费，制造成本高。
发明内容
本发明的目的是针对目前电子显示屏的问题，提供一种双层微结构的显示电浆模组及其制造方法，可以直接使用显示电浆替代现有的微杯结构或微胶囊，并在显示电浆中设置用于均匀分散、稳固和隔离显示电浆的电浆阻离阵列及间隔粒子层，起到支撑电极和控制显示电浆厚度的作用，同时有效防止显示电浆无序流动，保障了像素电极和透明电极之间电场方向的垂直度。
为实现以上技术目的，本发明的技术方案是：一种双层微结构的显示电浆模组，包括像素电极及位于像素电极上方的透明电极，其特征在于，所述像素 电极和透明电极间设有显示电浆及包围所述显示电浆的衬垫边框，所述像素电极和/或透明电极上设有用于均匀分散和稳固显示电浆的电浆阻离阵列，在所述电浆阻离阵列上吸附有间隔粒子层。

进一步地，所述显示电浆的厚度在2-70微米之间，且显示电浆中电泳液的粘度为100-100000厘泊，所述显示电浆中包含至少两种不同光电性能的电泳粒子。
进一步地，所述衬垫边框内可添加支撑微球，所述支撑微球的包括树脂微球、玻璃微球，且支撑微球的直径为2-60微米。
为了进一步实现以上技术目的，本发明还提出一种双层微结构的显示电浆模组制造方法，其特征是，包括如下步骤：

步骤五.在衬垫边框内涂覆导电银浆，所述导电银浆与像素电极电连接；
步骤六.先将显示区保护层压合在整个衬垫边框上，再将透明电极压合在衬垫边框和显示电浆上，在此过程中，大部分间隔粒子受到挤压被转移吸附在电浆阻离阵列的电浆阻离框上，形成间隔粒子层，然后进行固化，所述导电银浆与透明电极的导电层电连接；

4)本发明在像素电极和透明电极间设置电浆阻离阵列和间隔粒子层，与只有电浆阻离阵列结构相比，间隔粒子层和电浆阻离阵列起到了支撑电极和控制显示电浆厚度的作用，并将整个显示电浆分割为多个阻力框，在电场作用下，保证电泳粒子沿着电场方向垂直有序运动，保证了显示电浆的稳固性，提高显示屏对比度和显示效果；
