Abstract: Embodiments of the disclosed subject matter provide a display including a plurality of emissive surfaces, where each of the plurality of emissive surfaces has emissive devices that are deposited or attached in the same plane, with each of the plurality of emissive surfaces configured with independent scan and data drivers. The display may be configured to display an image that is a combination of light from the plurality of emissive surfaces, wherein each of the plurality of emissive surfaces renders an image that differs by at least one selected from the group consisting of: color resolution, fill-factor, viewing angle, and transparency. Embodiments also provide an augmented reality (AR), virtual reality (VR), or mixed reality (MR) system having a plurality of displays that each rendering an image based on the provided light of a different color spectrum, and one or more waveguides through which the light from the displays is combined.

Abstract: A method of fabricating a substrate for an organic light emitting device (OLED), by applying a volume-reducing substrate material onto a mold with topographical features that generates a smooth but non-flat surface on both sides of the substrate which can enhance light extraction of OLEDs that are built on top of the substrate. The resulting substrate includes surface features on a first substrate surface complementary to the surface features of a mold, such as spherical lens features, and surface features on a second substrate surface, such as dimple features, complementary to the curvature of the spherical lens features on the first substrate surface.
