Abstract
A method of driving a display device having a matrix of display material elements includes transmitting a picture signal voltage to each picture element electrode during an ON period of a respective switching element, applying a first modulation signal to a first wire during an OFF period of the switching elements associated with the first wire, and applying a second modulation signal to counter electrodes associated with the first wire during the OFF period of the switching elements associated with the first wire. Each picture element electrode of a plurality of the display material elements is connected to the first wire through a respective capacitance.
