摘要： Light extraction blocks, and OLED lighting panels using light extraction blocks, are described, in which the light extraction blocks include various curved shapes that provide improved light extraction properties compared to parallel emissive surface, and a thinner form factor and better light extraction than a hemisphere. Lighting systems described herein may include a light source with an OLED panel. A light extraction block with a three-dimensional light emitting surface may be optically coupled to the light source. The three-dimensional light emitting surface of the block may includes a substantially curved surface, with further characteristics related to the curvature of the surface at given points. A first radius of curvature corresponding to a maximum principal curvature k 1 at a point p on the substantially curved surface may be greater than a maximum height of the light extraction block. A maximum height of the light extraction block may be less than 50% of a maximum width of the light extraction block. Surfaces with cross sections made up of line segments and inflection points may also be fit to approximated curves for calculating the radius of curvature.

摘要： Organic light emitting devices (OLEDs) having improved outcoupling efficiency by using a discontinuous layer made of a translucent low- index material. Examples of low- index materials that can be used include inorganic alkali metal salts, such as LiF. The discontinuous layer (18) comprises discrete elements that are not connected to each other. For example, the discontinuous layer may be formed by depositing the low- index material to form islands instead of a continuous film. An organic layer (16) (e.g., a hole injection layer) comprising an organic material is disposed on the discontinuous layer such that the organic layer is in physical contact with the discontinuous layer. The discontinuous layer and/or organic layer may be designed to improve light outcoupling while minimizing any increase in electrical resistance or loss of active light emitting area caused by the discontinuous layer.
