  • Patent number: 10181566
    Abstract: An electrically conductive OLED carrier includes in this order a glazing substrate; an electrode arranged in a metal grid made up of strands; an electrically insulating light extraction layer under the metal grid; and a layer partially structured in its thickness. The layer of refractive is of index n3 of 1.7 to 2.3, and is located on the light extraction layer. The partially structured layer is formed from a region structured with cavities at least partially containing the metal grid; and from another region, called the low region, located on the light extraction layer. The separation H between the surface of the structured region called the high surface, and therefore that furthest from the substrate, and the surface of the metal grid called the upper surface, and therefore that furthest from the substrate is, in absolute value, smaller than or equal to 100 nm.

  • Publication number: 20160079560
    Abstract: An electroconductive support can include a layer that defines a cavity, and a conductive strand within the cavity of the layer. The conductive strand can have an upper surface within a central zone and a side zone, wherein the upper surface has a surface roughness within the central zone that is rougher than a surface roughness within the side zone. The electroconductive can further include an electroconductive layer and a passivation layer overlying the conductive strand. The relatively smoother upper surface within the side zone can allow the width of the passivation layer to be relatively narrow and still achieve acceptable leakage current. A method of forming the electroconductive support can be performed using a wet chemical technique to form the conductive strand while suppressing roughness along a side zone of the upper surface of the conductive strand.
