Abstract
A method for manufacturing a structure having a textured surface, including a substrate made of mineral glass having a given texture, for an organic-light-emitting-diode device, the method including supplying a rough substrate, having a roughness defined by a roughness parameter Ra ranging from 1 to 5 μm over an analysis length of 15 mm and with a Gaussian filter having a cut-off frequency of 0.8 mm; and depositing a liquid-phase silica smoothing film on the substrate, the film being configured to smooth the roughness sufficiently and to form the textured surface of the structure.
