Abstract
A display comprises independently addressable pixels, a pixel comprising first and second electrodes () disposed on a first substrate and spaced apart from one another. A counter electrode () is provided on a second substrate, with an electro-optical material provided between the first substrate and the second substrate. A controller, in use, applies a first voltage to the first electrode of the pixel, a second voltage different to the first voltage to the second electrode of the pixel, and a third voltage to the counter electrode of the pixel to define in the pixel at least one of a first region (), a second region () and a third region (). The first, second and third voltages are selected such that an area of the first region, second region and third region or each of the first, second region and third region defined in the pixel produces a desired greyscale level for the pixel.
