Abstract: Electronic Ink is new display device offering excellent resolution and high contrast under a wide range of viewing angles, requiring no external power to retain its image. However, designing electronic ink display device always posts a challenge to achieve high resolutions, flexible functionality, and low cost manufacturability. Since the number of controls to each individual pixel on a display increases with resolutions and display's functions, the display design becomes more complicated and drives to higher manufacture cost. Here, we propose to apply the threshold property of the electronic ink in response to applied electrical fields to design simplified displays with good resolutions, flexible functionality, and low cost manufacturability.
