Towards Video Display on Electronic Papers

The electronic paper has been successfully applied on electronic readers (E-Readers). Among all electronic paper technologies, the electrophoretic display (EPD) would be the most popular one due to its promising visual quality for showing text only contents or gray-tone images. However, playing videos/animations on the EPD is still a big challenge, thus none of the commercial E-Readers can support such a fancy feature. This drawback limits the application scenarios of the E-Readers. In this paper, we propose an integrated driving system for playing videos on the EPD. The system contains a new real-time signal processing hardware engine for video halftoning. In addition, the entire system is driven with a new driving waveform aiming at the reduction of residue images and visual flickers.
