Abstract:
The invention is drawn to a method of producing a transparent diffusive OLED substrate comprising the following successive steps: (a) lapping one face or both faces of a flat translucent glass substrate with an abrasive slurry, so as to obtain a flat glass substrate with at least one roughened surface having a roughness profile with an arithmetical mean deviation Ra of between 0.1 μm and 2.0μm, preferably between 0.15 μm and 1.5 μm, more preferably between 0.2 and less than 1.0 μm and most preferably of between 0.25 μm and 0.8 μm, (b) coating the roughened surface or one of the roughened surfaces with a high index glass frit having a refractive index of at least 1.7, preferably of between 1.7 and 2.2, the amount of the high index glass frit being sufficient to completely cover the roughness profile of the roughened surface after melting of said frit; (c) heating the coated substrate to a temperature above the melting temperature of the high index glass frit and below the softening temperature of the underlying substrate, so as to form high index enamel on one of the roughened surfaces.

Abstract:
Embodiments of the invention are directed to a layered organic light emitting diode (OLED) device comprising a buckled structure that provides an improved light output relative to flat OLED devices. The buckled structure has a fine buckling with a quasi- periodicity of 100 to 700 nm and a gross buckling of 10 to 20 μm. Embodiments of the invention are directed to a method of producing the OLED device comprising a buckled structure, where a transparent substrate is coated with a transparent elastomeric layer, upon which a thin metal layer of 20 to 100 nm is deposited at an elevated temperature. Upon cooling to ambient temperature, the metal layer buckles with the formation of a fine buckling with a quasi-periodicity of 100 to 700 nm and a gross buckling of 10 to 20 μm. The metal layer is oxidized to a transparent metal oxide layer with the retention of the buckling. Subsequent steps comprising deposition of at least an anode layer, an electroluminescence layer, and a cathode layer forms an OLED that has a buckling structure resulting from the buckled metal structure formed upon cooling.
