Textured glass for light extraction enhancement of OLED lighting

A device, comprising:

• an article comprising a textured glass substrate comprising a first face, a second face, a thickness of 30 μm to 2 mm measured from the first face to the second face, and at least one edge;
• the first face comprising an approximately planar surface comprising a first surface roughness, Ra1, of less than 2 nm;
• and
• the second face comprising a textured surface comprising a second surface roughness, Ra2, of from 200 nm to 600 nm and a plurality of surface features comprising a feature size, F, of 2 μm to 20 μm in diameter;
• a cathode;
• an anode;
• and
• at least one organic light emitting layer that is capable of emitting light,
• wherein the textured glass substrate is coupled to the device such that light emitted from the organic light emitting layer passes through the textured glass substrate.
