Abstract:A three-color electrophoretic display (EPD) can solve the defect of an insufficient color display of black/white EPDs, but it is difficult to achieve a high red saturation due to the same driving polarity between black and red electrophoretic particles. In this work, a separation stage was proposed in the driving process to increase the red saturation in three-color EPDs. Firstly, red particles’ motion was analyzed by the electrophoretic theory and Stokes’ theorem to optimize driving parameters. Secondly, the … Show more
