The invention relates to a conductive support for an OLED, comprising: a dielectric sub-layer having an optical thickness L1 larger than 20 nm and smaller than 180 nm, comprising a first crystalline contact layer made from zinc oxide and preferably doped; a first silver layer having a thickness smaller than 20 nm; a separating dielectric layer having a given optical thickness L2 larger than 80 nm and smaller than 280 nm, comprising, in this order: a zinc layer, having a thickness e2 and preferably doped, directly on the first silver layer; an optional amorphous layer made from tin and zinc oxide, or made from indium and zinc oxide, or made from indium, zinc and tin oxide, having a thickness e smaller than 15 nm; a second layer of zinc oxide having a thickness ec2, the sum of the thicknesses eC2+e2 being at least 30 nm; a second silver layer having a thickness smaller than 20 nm; a metal overlying blocking layer having a thickness smaller than 3 nm; and a dielectric, electrically conductive overlying layer.
摘要:
The invention relates to a material comprising: (i) a substrate which is provided with a titanium oxide-based coating which is topped with a thin hydrophilic layer, said thin hydrophilic layer forming at least part of the external surface of the material and containing no titanium oxide; or (ii) a substrate which is provided with a coating based on titanium oxide and silicon oxide, whereby the titanium oxide content at the external surface of the material is non-null and the silicon oxide content is greater on the surface than inside the layer. The invention relates to the use of said material in order to prevent mineral fouling from being deposited on the external surface in the absence of water runoff.
