Abstract

We present an enhancement scheme for optical extraction from Organic based LEDs (OLEDs). Enhancement layers, developed by Mitsubishi Chemical Corporation, facilitate the engineering of scattering near an OLED's emitter. An approximate scattering model based on rigorous optical field calculations of the OLED structure is described and optimised. Experimental and numerical results indicate that up to 2-fold efficiency enhancements are achievable across a broad spectral range.
