Abstract
An organic light-emitting diode (OLED) device, comprising: first and second non-metallic transparent electrodes, and one or more layers of organic material formed between the first and second non-metallic transparent electrodes, the layers of organic material including one or more light-emitting layers; and one or more non-metallic reflective layers located on a side of either of the first or second non-metallic transparent electrodes opposite to the organic material layers; wherein the device further comprises a light transmissive scattering layer in optical contact with the organic material layers and the electrodes or wherein at least one of the one or more non-metallic reflective layers comprises a reflective scattering layer in optical contact with the organic material layers and the electrodes. Additionally, a low-index layer is preferably employed in various embodiments to improve device sharpness.
