Abstract
A drive method is provided for a display device using the movement of 5 charged particles with a pixel area, with each pixel having first and second drive electrodes (20,23; 22) and a pixel electrode (26). The method comprises a reset phase to move the particles in each pixel towards the first drive electrode (20,23), a pixel data loading phase, to cause selected particles either to stay in the vicinity of the first drive electrode (20,23) or move towards the 10 pixel electrode (26), and a drive phase to distribute the particles which have moved towards the pixel electrode over the pixel electrode (26). The address phase is line-by-line but can be made short, and the other phases can be carried out in parallel for all pixels, saving time.
