    Abstract: An OLED is disclosed that includes an enhancement layer having optically active metamaterials, or hyperbolic metamaterials, which transfer radiative energy from the organic emissive material to a non-radiative mode, wherein the enhancement layer is disposed over the organic emissive layer opposite from the first electrode, and is positioned no more than a threshold distance away from the organic emissive layer, wherein the organic emissive material has a total non-radiative decay rate constant and a total radiative decay rate constant due to the presence of the enhancement layer, and the threshold distance is where the total non-radiative decay rate constant is equal to the total radiative decay rate constant; and an outcoupling layer disposed over the enhancement layer, wherein the outcoupling layer scatters radiative energy from the enhancement layer to free space.

    Abstract: A display includes a frontplane having multiple pixels in a first pixel region and multiple pixels in a second pixel region. At least one display characteristic in the first pixel region is different from at least one display characteristic in the second pixel region. The at least one characteristic is selected from the group consisting of resolution, cavity mode, outcoupling, color and color filter. A display with a curved scan line and variable spaced data line backplane architecture is also described. In addition, a method of reducing power requirements in a display is described.
