An electroluminescent display (10) includes thin conductive strips on a phosphordeposited area (20). One aspect of the invention is directed to a device including a dielectric carrier (22) supporting a first conductive bus (12) connecting to first conductors (16) and a second conductive bus (14) connecting to second conductors (18). The first and the second conductors are arranged in close proximity to one another, so that a phosphor based carrier can be located therebetween to permit an electric field set up by voltage applied between the first and the second conductors to generate light via the phosphor. A dielectric layer disposed between the conductors enhances the brightness of the light generated. The electroluminescent display can be incorporated as a part of mirror or liquid crystal device.

L'invention porte sur un écran luminescent comportant de fines raies conductrices disposées sur surface revêtue d'un dépôt de phosphore. L'une des variantes de l'invention porte sur un dispositif comportant un support diélectrique portant un premier bus conducteur relié à de premiers conducteurs, et un deuxième bus conducteur relié à de seconds conducteurs. Les premiers et seconds conducteurs sont très proches, ce qui permet de placer entre eux un support à base de phosphore et de faire produire de la lumière par le phosphore sous l'effet d'un champ électrique due à une tension électrique appliquée entre les conducteurs. Une couche diélectrique placée entre les conducteurs renforce la luminosité de la lumière émise. Le dispositif électroluminescent peut s'incorporer à un miroir ou à un dispositif à cristaux liquides.
