Abstract

The invention relates to electrophoretic layers containing at least five different particles, and to driving methods for displaying at least five, and in some embodiments, six different colors at each pixel or sub-pixel. The electrophoretic layers may also contain uncharged neutral buoyancy particles, and the driving methods may include special shaking waveform sequences.
