Abstract
An OLED device includes an OLED structure having a curved shape and/or a concave surface. The OLED structure may function both as light source and as a reflector configured to concentrate light produced by the structure. An OLED may be formed in the shape of a reflector so that light is provided at the concave surface and so that light is reflected from the concave surface at the same location along the surface. The OLED structure can include a flexible substrate formed to shape, along with an organic layer and electrode layers coated over a substrate surface either before or after the substrate is formed. The OLED structure may also include a microcavity OLED, a grating layer, and/or one or more optical elements that alter the characteristics of the light emitted at an aperture of the structure.
