Patent ID: 6998774

Claim:
An addressable electroluminescent display comprising: a first layer comprising an electrically-conductive, transparent, front-electrode; a second layer comprising a plurality of electrically-conductive, rear-electrode segments; a third layer located between the first and second layers and comprising electroluminescent material; a fourth layer comprising an plurality of electrically-conductive tracks each of which is electrically connected at a first end to at least one of the rear-electrode segments; a fifth layer located between the fourth layer and a sixth layer (defined below), comprising dielectric material and following substantially the path of the electrically-conductive tracks; and a sixth layer located between the third and the fifth layers, comprising an electrically conductive backplane which: is electrically connected to the front-electrode in front of the backplane such that the potential difference across the third layer in the region of the sixth layer is substantially zero; and follows substantially the path of the electrically-conductive tracks; wherein, in use, a driving voltage for driving the illumination of an area of the display is supplied across the first layer and a rear electrode segment in the second layer.
