具体实施方式
下面结合附图和具体实施例对本发明作进一步说明，以使本领域的技术人员可以更好地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。
如图1所示，本发明的一种立柱型电浆显示模组。包括第一基板1及与其相对设置的第二基板2，所述第一基板1和第二基板2之间形成电浆显示腔，所述电浆显示腔内填充电浆粒子3，所述电浆粒子3包含白粒子和黑粒子。如图1中所示，颜色深的为电浆黑粒子，颜色浅的为电浆白粒子。应当理解的是，所述电浆粒子3还可以包括双色、三色或多色颜料粒子，可以根据需要进行选择，此处不做限定。
其中，第一基板1与第二基板2可以采用玻璃基板，第二基板2可以采用TFT(薄膜晶体管，Thin Film Transistor)玻璃基板。
所述第一基板1设置有滤光层4，滤光层4可以设置在第一基板1朝向所述第二基板2的表面也可以设置在第一基板1背离所述第二基板2的表面，所述第二基板2朝向第一基板1的表面设置有像素电极层5。
所述像素电极层5上设置有朝向所述第一基板1方向延伸的电浆隔离结构 6，所述滤光层4的朝向所述第二基板2的表面设置有立柱结构7，
所述立柱结构7与所述电浆隔离结构6适配以固定所述第一基板1和所述第二基板2。所述立柱结构7可以如下设置：所述立柱结构7与所述电浆隔离结构6朝向所述第一基板1的一端紧密接触。所述滤光层4和所述立柱结构7朝向所述第二基板2的表面均设置有导电介质层9。其中，所述立柱结构7的材料包括有机膜，导电介质层9的材料可以选用ITO；其中ITO膜是掺锡氧化铟膜(IndiumTinOxide)，具有高的导电率、高的可见光透过率、高的机械硬度和良好的化学稳定性。
本实施例中，可在立柱结构7朝向所述第二基板2的表面设置卡槽，电浆隔离结构6的顶部可嵌入卡槽中并与立柱结构7相贴合。利用立柱结构7贴合电浆隔离结构6，可以增加显示屏整体结构的强度，减少浆料的移动，同时减少上下盖板受外力影响造成的形变，提升整体抗压性。
在本发明的一个实施例中，所述滤光层4包括多个间隔设置的彩色滤光片41，其中彩色滤光片41包括但不限于RGB三色滤光片，通过彩色滤光片41实现多种颜色的显示。所述立柱结构7连接相邻的两个彩色滤光片41，能够减少对显示效果的影响。
需要注意的是，可以在每相邻两个所述彩色滤光片41之间设置填充介质42。当滤光层4设置在第一基板1朝向第二基板2的表面时，所述立柱结构7设置在所述填充介质42的表面，当滤光层4设置在第一基板1背离第二基板2的表面时，则是直接设置在第一基板1朝向第二基板2的表面。所述填充介质42材料优选为透明树脂。由于电浆隔离结构6围绕单个像素(色块)一圈，使用填充介质42能够填充相邻两个彩色滤光片41的间隙，使得滤光层4平整。在其他实施例中，相邻两个彩色滤光片41的之间也可不设置填充介质42，为了能够更好地设置立柱结构7，设置填充介质42为优选方案。
需要注意的是，立柱结构7连接相邻的彩色滤光片41，可以在每个相邻的彩色滤光片41之间都设置一个立柱结构7，也可以设置多个立柱结构7，也可以仅在关键的位置设置立柱结构7，为此立柱结构7具体设置的数量与位置在此不作限定，具体参照图2至图5所示，只需要满足立柱结构7与电浆隔离结构6之间的位置关系与连接关系即可。
在本发明的一个实施例中，所述电浆填充区内设置支撑结构8。具体所述支撑结构8包括支撑微球，所述支撑微球分别与所述导电介质层9与所述像素电极层5相切。支撑微球主要起到支撑和固定作用，提高屏幕的耐按压性，使其在显示过程中，按压屏幕，图像不会模糊及变形，提高显示图像稳定性。
在本发明的一个实施例中，所述像素电极层5包括多个呈阵列式分布的像素电极51，相邻两个所述像素电极51之间形成间隙52，所述电浆隔离结构6覆盖所述间隙52。其中，电浆隔离结构6为由像素电极层5向滤光层4延伸的梯形结构，其截面形状为梯形，主要起到隔离电浆粒子3的作用。
本实施例中，所述电浆隔离结构6可均匀分布于每个像素电极51的四个角位置处，也可以不规则地分布在像素电极51的各个边的位置处。
本发明的另一个技术方案提供了一种电浆显示屏，包括上述任意一种立柱型电浆显示模组。作为显示装置的具体实施方式，所述显示装置具体可以为微胶囊或微杯的电子纸显示屏、双稳态反射液晶显示屏以及LCD液晶显示屏。关于显示装置的效果具体可以参照前文的显示电浆模组的效果，此处不再赘述。
本发明提供的电浆显示模组的制作过程具体包括：首先在上玻璃基板上镀彩色滤光层4，形成一个个不同颜色的色块，同时用在彩色滤光色块的间隙之间蒸镀一层透明树脂层，使上基板表面平整，接着在下基板组件上设置电浆隔离结构6。然后通过Mark点定位技术对立柱结构7与电浆隔离结构6的位置进行定位，使立柱结构7与电浆隔离结构6的上表面贴合安装。
最后所应说明的是，以上具体实施方式仅用以说明本发明的技术方案而非限制，尽管参照实例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。
