Printing technology is an ideal choice for low-cost, large-scale display process and an important breakthrough in the global display manufacturing industry. Electrowetting shows that the pixel structure is simple and mainly depends on wet process technology, which is an excellent carrier for the application of printing display technology. The key pixel structure materials involved in the printed electrowetting display technology and its printing process are reviewed. The various process routes of electrowetting display ink printing and filling are discussed. The challenges and prospects of the current printed electrowetting display technology are summarized The possible solution to the path and direction of development.
