A fast response speed of a pixel is important for electrowetting displays (EWDs). However, traditional driving waveforms of EWDs have the disadvantage of long response time. So, a driving waveform, which based on overdriving voltages and charge trapping theory, was proposed in this paper to shorten the response time of EWDs. The driving waveform was composed of an overdriving stage and a driving stage. Firstly, a simplified physical model was introduced to analyze the influence of driving voltages on the response time. Then, an overdriving voltage was applied in the overdriving stage to increase the respond speed of oil, and a target voltage was applied in the driving stage to obtain a target luminance. In addition, the effect of different overdriving voltages and overdriving time values on the response time was analyzed by charge trapping theory to achieve an optimal performance. Finally, the driving waveform was imported into an EWD for performance testing. Experimental results showed that the response time of the EWD can be shortened by 29.27% compared with a PWM driving waveform.

像素的快速响应速度对于电润湿显示器（EWD）至关重要。然而，EWD的传统驱动波形具有响应时间长的缺点。因此，本文提出了一种基于过驱动电压和电荷捕获理论的驱动波形，以缩短EWD的响应时间。驱动波形由过驱动级和驱动级组成。首先，引入简化的物理模型来分析驱动电压对响应时间的影响。然后，在过驱动阶段施加过驱动电压以提高油的响应速度，并且在驱动阶段施加目标电压以获得目标亮度。此外，通过电荷俘获理论分析了不同的过驱动电压和过驱动时间值对响应时间的影响，以获得最佳性能。最后，将驱动波形导入EWD以进行性能测试。实验结果表明，与PWM驱动波形相比，EWD的响应时间可缩短29.27％。
