Abstract :
A driving waveform for electrophoretic displays with high image quality is proposed. The proposed driving waveform shows good performance compared to the conventional waveforms. By adding two voltage levels, the number of grey levels expanded from 8 to 165. In addition, the average response time improved from 90 to 61 ms.
