Abstract
A lookup table provides voltage waveforms for transitions between a plurality of discrete pixel states forming a set that can be ordered in consecutive states according to a reflectivity of the pixel. An image controller repeatedly executes, in a consecutive drive phase, the steps of retrieving an initial state and update state, matching, when the initial and update states are different, in the ordered set of pixel states of the lookup table, a consecutive state and a corresponding consecutive waveform, the consecutive state forming a path, according to the consecutive drive phase, from the initial state to the update state in the set of pixel states, storing the consecutive state in the memory as new initial state; and controlling a voltage driver to drive the pixel from the initial state to the consecutive state using said consecutive waveform.
