To design various electronic papers, the panel designers may adopt different types of electrophoretic materials and active matrix backplanes for resolution, speed, and contrast ratio considerations. The electrical and optical characteristics are quite different under different design requirements so that a good display timing controller should provide an easy way to modify waveforms accordingly. In this paper, we present a configurable timing controller for active matrix electrophoretic displays (EPD). The design principle of driving waveforms is first discussed and the controller can support all variations of driving waveforms with pulse width modulation. The performance of the controller has been verified by several practical EPD systems.
