A novel driving scheme for oil-splitting suppression in Electrowetting display

Abstract

To achieve quick-response Electrowetting displays with an accurate gray level performance for image applications, oil-splitting is an important issue which needs to be optimized. The study found that oil patterns affect the pixel aperture ratio. This paper proposes a novel driving waveform that can suppress an oil-splitting phenomenon without affecting the refresh rate. The experimental results show that the proposed driving scheme can improve the oil-splitting problem and increase the aperture ratio of pixels. This is of great practical significance for improving the Electrowetting display application. Moreover, a portable and highly integrated driving waveform control system is implemented in this paper.
