Abstract:
Devices, components and fabrication methods are provided for improving the efficiency of OLED displays. An outcoupling component such as a microlens array (MLA) is attached to an OLED, with a relatively small distance between the MLA and the OLED. Cross-talk and back scattering are reduced by the use of colored lenses, focusing layers, and other methods.
