Abstract
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.
