Abstract
The present invention is drawn to a transparent diffusive OLED substrate comprising the following successive layers: (a) a transparent flat substrate (1) made of mineral glass having a refractive index of between 1.45 and 1.65, (b) a rough low index layer comprising mineral particles, said mineral particles being attached to one side of the substrate by means of a sol-gel mineral binder, the mineral particles near, at or protruding from the mineral binder's surface creating a surface roughness characterized by an arithmetical mean deviation R a comprised between 0.15 and 3 µm, the mineral particles and mineral binder both having a refractive index of between 1.45 and 1.65; (c) a high index layer made of an enamel having a refractive index comprised between 1,8 and 2,1 covering the rough low index layer; and to a process for making such a diffusive OLED substrate.
