The manufacturing method for an electrophoretic display

The present invention relates to a manufacturing method for an electrophoretic display applying optical polymer material. The main characteristic is that the charged pigment particles are confined with optical polymer material so as to achieve the object of electrophoretic display. In the manufacturing process, a first layer of optical polymer material is coated on an auxiliary substrate having a buffer layer for performing an optical polymerization manufacturing process. After the polymerization, on the first layer of the optical polymer material layer, the manufacturing process required by the electrophoretic display is further performed. After a second layer of optical polymer material is coated on a substrate required by the electrophoretic display having a plurality of electrode patterns, by using a mask exposure, the optical polymer material is solidified to form a polymer wall, or a molding method is applied with ultraviolet irradiation for solidifying the optical polymer material so as to form the polymer wall. Next, in a hole formed by the polymer wall, the mixture formed by the charged pigment particles and a few amount of optical polymer material is filled, and the auxiliary substrate aligned with the substrate so as to perform the mask exposure polymerization manufacturing process. Therefore, the auxiliary substrate is combined with the substrate. Finally, the auxiliary substrate is stripped out so as to finish the manufacturing of a single substrate electrophoretic display. Furthermore, an electrophoretic display without a substrate can be manufactured. By applying a display manufacturing method according to the present invention, the number of the steps for the manufacturing process is reduced, and the conditions for the manufacturing process can be more easily controlled. In addition, the electrophoretic display according to the present invention can have various display modes.
