The design considerations for full-color e-paper

Electrophoretic display (EPD) has been widely used in e-paper applications because of its flexibility, low power consumption, good sunlight visibility. The commercial success of monochromic EPD has boosted the development of full- color EPD to further satisfy people’s demand for various applications. However, many challenges shall be overcome before commercializing it. In this paper, we will introduce the EPD’s fundamental operation, the design of driving waveform for optimizing the opto-electronic performance, and the strategies for achieving full-color EPD as well as a color EPD prototype fabricated by transfer method.
