The invention provides a method and apparatus for manufacturing an electrophoretic display device, relating to the technical field of electrophoretic display. The invention has the purposes of easily filling an electrophoretic liquid into a micro cup array of the electrophoretic display device and improving the production efficiency of the electrophoretic display device. The method for manufacturing the electrophoretic display device comprises the following steps of: forming the micro cup array on a first electrode layer of the electrophoretic display device by using the cup manufacturing technology; and filling the electrophoretic liquid with certain pressure into the micro cup array in vacuum state. The apparatus for manufacturing the electrophoretic display device comprises a cup manufacturing device, a vacuum device and an electrophoretic liquid filling device, wherein the cup manufacturing device is used for forming the micro cup array on the first electrode layer of the electrophoretic display device by using the cup manufacturing technology; the vacuum device is used for providing a vacuum environment so that the micro cup array stays in vacuum state; and the electrophoretic liquid filling device is used for filling the electrophoretic liquid with certain pressure into the micro cup array in vacuum state. The method and the apparatus provided by the invention are used for manufacturing the electrophoretic display device.
Description
technical field [0001] The invention relates to the technical field of electrophoretic display, in particular to a manufacturing method and manufacturing equipment of an electrophoretic display device. Background technique [0002] Electrophoretic display is a new type of display technology. It has the characteristics of both paper and electronic devices. It is not only in line with people's visual habits, but also convenient and fast. Electronic ink technology, one of the key technologies of electrophoretic display, is to suspend charged electrophoretic particles in a dispersion medium solvent to form a suspension system. Always change the displayed graphics and text. [0003] The principle of the micro cup electrophoretic display is to disperse the charged electrophoretic particles in the dispersion medium solvent to form a colloidal electrophoretic liquid, encapsulate it in a special micro cup, apply an electric field to the dispersion system, and the charged electrophor...
