The display quality, as well as the speed of electrophoretic displays (EPDs), is highly affected by the design of driving waveforms. A typical driving waveform contains the phases of image erase, particle activation, and driving each pixel to the target gray level. Due to the difficulty of modeling a complete EPD device, the designers still lack a systematic approach to driving waveform design. In this paper, we study the property of the viscosity of the suspension, characterize the response latency of the device, and propose a new driving waveform. The experimental results show that the proposed approach can effectively reduce driving time while still maintaining good image quality.
