ELECTROCONDUCTIVE BASE FOR ORGANIC LIGHT-EMITTING DIODE (OLED), OLED, INCLUDING SAID BASE, AND ITS MANUFACTURING Russian patent published in 2019 - IPC H01L51/52 

FIELD: electricity.

SUBSTANCE: invention can be used to create an electroconductive base for OLED. Essence of the invention consists in that the electroconductive base for OLED comprises: a glass substrate of organic or mineral glass with an index n₁ of refraction from 1.3 to 1.6, having first main side, called first surface; and an electrode supported by a glass substrate on the same side as the first surface, which electrode comprises a layer arranged in the form of a mesh, called a metal mesh, which mesh is made of metal(s) having surface resistance of less than 20 Ohm/square, and has thickness e₂ at least 100 nm, wherein the mesh is made of threads, wherein the filaments have a width A smaller than or equal to 50 mcm, and are separated by an annular gap B less than or equal to 5,000 mcm, wherein the threads are separated by a plurality of electrically insulating non-electroconductive zones with a refraction index greater than 1.65, on the same side as first surface (11), base comprises: electrically insulating light-emitting layer under metal mesh; and electrically insulating layer, partially structured in its thickness, wherein this layer has a given composition and exponent n₃ of refraction from 1.70 to 2.3 and is arranged on light-release layer, which partially structured layer is formed by: area located farthest from light- emitting layer, structured cavities containing metal mesh, wherein this area contains non-electroconductive zones; and another area, called lower area, located under metal mesh and on light- emitting layer, and by the fact that mesh is recessed inside from surface, called upper surface of non-electroconductive zones, and the gap H between the upper surface and the metal mesh surface is more than 100 nm, wherein H is measured between the middle of the surface of the threads and the upper surface, and in that the threads along their length have a central area between the side zones which are flush with the upper surface.

EFFECT: improved performance of an OLED device.
