ELECTROCONDUCTIVE SUPPORT FOR AN OLED, OLED INCORPORATING AND MANUFACTURING Russian patent published in 2018 - IPC H01L51/52 

FIELD: electronic equipment.

SUBSTANCE: present invention concerns electroconductive support (100 to 300) for an OLED comprising, in the following order: glass substrate (1), metal grid (2) electrode with strands (20), electrically insulating light extraction layer (41), under metal grid (2), layer (3) the thickness of which is partially structured, with a given composition, with refraction index n₃ from 1.7 to 2.3, which is on the light extraction layer, said partially structured layer is formed: of structured region (31), with cavities at least partially containing the metal grid, of another region, called low region (30), on the light extraction layer. Difference H between the so-called top surface, which is furthest from the substrate, of structured region (31) and the upper surface, which is furthest from the substrate, of metal grid (2) is, as an absolute value, less than or equal to 100 nm.

EFFECT: invention provides improved performance of the OLED.
