摘　　要：Bistable electrowetting display(EWD)is a promising low-power electronic paper technology,where power is consumed only during the switching between two stable states;however,it is not required for state maintenance once switched.In this paper,a bistable electrowetting device with non-planar designed controlling electrodes is fabricated by a fully conventional photolithography process.The device has potential for video display applications with a controllable gray scale.The novel electrode design realizes a lower driving voltage and a higher contrast between two stable states than the EWDs with planar electrodes reported previously.Bistable electrowetting display(EWD) is a promising low-power electronic paper technology, where power is consumed only during the switching between two stable states; however, it is not required for state maintenance once switched. In this paper, a bistable electrowetting device with non-planar designed controlling electrodes is fabricated by a fully conventional photolithography process. The device has potential for video display applications with a controllable gray scale. The novel electrode design realizes a lower driving voltage and a higher contrast between two stable states than the EWDs with planar electrodes reported previously.
