Abstract: A system and method for the fabrication of high efficiency OLED devices and more specifically, the fabrication of OLED panels optically coupled with impact resistant, transparent structures which permit operation of the OLED panel while providing impact resistance. The OLED device can be built directly on an impact resistant transparent structure, or attached to an impact resistant transparent structure after it is built on other types of substrate. The impact resistant transparent structure can be a toughened layer, such as a glass layer, an energy absorption layer, such as Polycarbonate (PC), or a combination of both. The OLED device is configured to transmit light through the impact resistant transparent structure to the viewer, and the impact resistant transparent structure provides impact resistance for the OLED from the force of any impacting object.

Abstract: A flexible multilayer scattering substrate is disclosed. Built on a flexible supporting layer, the multilayer contains one or more scattering layers and other functional layers so that it can extract the trapped light in substrate and waveguide of an OLED. The processing of each layer is fully compatible with large area, flexible OLED manufactory, and by controlling processing conditions of each incorporated layer, the substrate microstructure can be tuned. Topographic features can be created on the top surface of substrate by changing the thickness and properties of the multilayer.

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.
