Abstract
A display includes at least one layer having a memory effect electro-optical property and enclosed between first and second families of electrodes. The display also includes a generator suitable for generating a plurality of voltages at different phases. At least one of the families of electrodes is subdivided into at least two subfamilies of parallel electrodes receiving respective different phase sustain voltages. This gives rise to a considerably drop in electrical power consumption, to an improved manufacturing yield, and makes it possible to provide larger-sized displays and/or operation at a higher image-writing speed, etc.
