Organic light emitting diode with surface modification layer
Patent
·
OSTI ID:1485276
An organic light emitting diode includes a substrate having a surface modification layer. The surface modification layer includes a first film and a second film. The first film has a coefficient of expansion that is greater than the coefficient of expansion for the second film. The second film has ridges and troughs. A method of making a surface modification layer. A first film is formed over a substrate. The coated substrate is heated to expand the first film to a second surface area. A second film is formed over the expanded first film. The substrate coated with the first and second films is cooled to form ridges and troughs in the second film.
