Abstract: An OLED having an organic layer formed of a dopant and a host, where the organic layer is disposed between an anode and a cathode is disclosed. The dopant's concentration level in the organic layer, along a direction perpendicular to the first and second planar surfaces of the organic layer, defines a novel concentration gradient that enhances the OLED's efficiency.

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.
