Waveforms for driving an electrophoretic display including a color filter between a viewer and the electrophoretic medium. Because the waveform results in each image update visiting the white state before the final state, the overall gamut is larger in aggregate and more predictable than simply driving the electrophoretic display including a color filter with the waveforms that are used for black and white grayscale displays.

Drive scheme for improved color gamut in color electrophoretic displays

There are provided methods for driving an electro-optic display having a plurality of display pixels, a such method includes applying a first waveform chosen from a first set of waveforms for black-to-white and white-to-white transitions if a pixel is determined to display color, and applying a second waveform chosen from a second set of waveforms for black-to-white and white-to-white transitions if a pixel is determined to display a grayscale image.
