摘要

双稳态电润湿显示器仅在状态切换时耗能，在状态稳定时无耗能，是一种非常有潜力的低能耗电子纸显示技术。本文设计和实现了通过常规光刻工艺制备一种非平面电极结构的双稳态电润湿器件。该器件不仅具备视频响应速度，而且有潜力实现可控的像素灰阶。与现有平面电极结构双稳态电润湿器件相比，该新型电极结构可实现更低驱动电压和更高对比度。

Abstract

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 photo- lithography 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.
