Patterned organic light emitting diode (OLED) with enhanced light extraction

Abstract:

An organic light emitting diode (OLED) incorporating an enhanced light extraction apparatus in the transparent conductive oxide layer is disclosed. The apparatus for light extraction may comprise a transparent substrate, a transparent electrode comprising one or more discontinuities, and an organic light emitting material stack. The transparent electrode may be disposed on the transparent substrate and comprise a series of features or discontinuities that enhance light extraction improve energy efficiency in the OLED device. The discontinuities may be discrete or continuous and may interrupt the conductivity of the transparent conductive oxide layer.
