  • Publication number: 20110043104
    Abstract: An electroluminescence (EL) device includes a planar electroluminescence (EL) layer, on the rear of which two segment electrodes are disposed insulated next to and nested inside each other in an electrode plane and can be connected to an alternating current source, and on the front of which at least one transparent front electrode, particularly in the form of one or more graphical elements, are disposed in an insulated manner. In such an EL device, luminosity that is practically independent of the shape of the counter-electrodes and uniform across the surface is provided, and a formation of the graphical elements by simple cutting out or stamping out is enabled, in that the nesting of the segment electrodes is configured such that the segment electrodes are alternately disposed in two independent directions of the electrode plane.

  • Publication number: 20090206750
    Abstract: An electroluminescence apparatus (10, 10?, 10?) having a layer sequence (12, 13, 14), which is arranged on a substrate (15) and has two electrode layers (12, 14), and an optically active dielectric intermediate layer (13) which is located between the electrode layers (12, 14) and is prepared by detachably applying the layer sequence (12, 13, 14) to an auxiliary mount (11) and adhesively applying the layer sequence (12, 13, 14) to the substrate (15) with the face which faces away from the auxiliary mount (11) of the layer sequence (12, 13, 14) which is located on the auxiliary mount (11) and detaching the auxiliary mount (11) from the layer sequence (12, 13, 14), which adheres to the substrate (15).
