With the increasing popularity of portable electronic products, flexible displays (such as electronic paper (e-paper), electronic book (e-book), etc.) have gradually attracted the attention of the market. Generally speaking, electronic paper (e-paper) and electronic book (e-book) use electrophoretic display technology to achieve the purpose of display. Taking an e-book that can only display black and white as an example, its sub-pixels are mainly composed of black electrophoretic fluid and white charged particles doped in the black electrophoretic fluid. By applying a voltage, the white charged particles can be driven to move, so that each The pixels display black, white, or different shades of gray. In addition, in color e-books, in order to display the three primary colors of red, green, and blue, it is necessary to form red electrophoretic fluid, green electrophoretic fluid, and blue electrophoretic fluid doped with white charged particles in different micro-cups. ), there are mainly two known methods at present, one of which is to form electrophoretic fluids of different colors in microcups by means of inkjet printing, and the other is to form electrophoretic fluids of different colors in microcups through a multi-channel exposure and development process. The electrophoretic solution is sealed in the microcup. the

In addition, although the problem of color mixing of the electrophoretic fluid can be improved by filling the electrophoretic fluid of different colors into the microcups by using the multi-channel exposure and development process, many materials are wasted in the process, so that the cost cannot be further reduced. the
