Abstract: An organic light emitting diode (OLED) incorporating a light extraction film is disclosed. The light extraction film may be used for enhancing light extraction from a light source. The light extraction film may include an array of 3-D microprisms, an interstitial region, and a glass layer. Each microprism may have an area of a first surface (A1) and an area of a second surface (A2). The A2 may be equal to or less than A1. Each microprism may have a pair of oppositely disposed sidewalls. The interstitial region may be disposed between the pair of oppositely disposed sidewalls of adjacent microprisms. The interstitial region may have an index of refraction less than an index of refraction of the microprism. The glass layer may be attached to the first surface of the array of 3-D microprisms. The glass layer may be less than about 1 mm thick.
