In this paper, we propose a driving waveform with a complex ramp pulse for an electrowetting display system. The relationship between the contact angle and viscosity of inks was calculated based on the fluid-motion characteristics of different viscosities. We obtained the suitable range of viscosity and voltage in the liquid-oil-solid three-phase contact display system. We carried out model simulation and driving waveform design. The result shows that the driving waveform improves the response speed and aperture ratio of electrowetting. The aperture ratio of electrowetting pixels is increased to 68.69%. This research is of great significance to optimizing the structure of fluid material and the design of driving waveforms in electrowetting displays.
在本文中，我们为电润湿显示系统提出了一种具有复杂斜坡脉冲的驱动波形。基于不同粘度油墨的流体运动特性，计算了接触角与油墨粘度之间的关系。我们在液 - 油 - 固三相接触显示系统中获得了合适的粘度和电压范围。我们进行了模型模拟和驱动波形设计。结果表明，该驱动波形提高了电润湿的响应速度和开口率。电润湿像素的开口率提高到了68.69%。本研究对于优化电润湿显示器中流体材料的结构和驱动波形设计具有重要意义。
