METHOD FOR MANUFACTURING A STRUCTURE WITH A TEXTURED SURFACE AS A MOUNTING FOR AN ORGANIC LIGHT-EMITTING DIODE DEVICE, AND OLED STRUCTURE WITH A TEXTURED SURFACE

摘要

A production method and a structure having a textured surface forming the support for an organic-light-emitting-diode device, which structure is provided on a transparent substrate made of mineral glass on which is optionally deposited an interface film made of mineral glass, the profile of the texture of the surface comprising protrusions and troughs which are defined by an FT or a roughness parameter Rdq such that the protrusions are not too pointed and such that an increase in the extraction efficiency is ensured. The method especially consists in depositing on the glass substrate a coating film and in ensuring a contraction of the assembly by heating and cooling.
