摘要： A defocused optic (110, 210) for mixing of light output from a multichip LED (101, 201). The defocused optic (110, 210) includes an outer reflector having a concave inner surface (122, 26, 222, 226) with a varied profile. The outer reflector surrounds an interior reflector (140, 240) having a convex surface (142, 242). The convex surface (142, 242) of the interior reflector (140, 240) is positioned to generally face a multichip LED (101, 201) and may optionally have a varied profile. Appropriate selection of the design parameters of the profiles of the concave inner surface(122, 126, 222, 226), the profile(s) of the convex surface (142, 242), and the rotational angular range over which said profiles are present enables appropriate mixing of the light output from a given multi-chip LED (101, 201).

摘要： The invention relates to an organic light-emitting device (OLED) comprising at least: a first electrode (102); a second electrode (105); an organic light emissive layer (104) arranged between said first electrode and said second electrode; and an organic charge transport layer (103) arranged between said first electrode and said emissive layer, wherein i) the charge transport layer is patterned or provided with a periodic surface structure on a surface of the charge transport layer facing the emissive layer, and/or ii) an alignment layer (406) which allows for charge transport to the emissive layer is provided between said charge transport layer and said emissive layer, which alignment layer promotes alignment of the optical dipoles of molecules of said light emissive layer towards a common preferred direction of the molecular axes. The use of the patterned or structured charge transport layer and/or the alignment layer provides improved light out coupling from the OLED layer stack, i.e. increased external quantum efficiency.

摘要： A method of manufacturing a thin-film electronic device comprises applying a plastic coating to a rigid carrier substrate (12) using a wet casting process, the plastic coating forming a plastic substrate (22). The plastic material has a coefficient of thermal expansion greater in a first direction perpendicular to the substrate plane than in a second direction parallel to the substrate plane. Thin film electronic elements are formed over the plastic substrate and the rigid carrier substrate is released from the plastic substrate by a heating process which expands the plastic substrate preferentially in a direction perpendicular to the substrate plane. The anisotropy of the thermal expansion in the plastic substrate of the invention enables the expansion of the substrate during the thermal lift-off process to be in the perpendicular direction. This has been found to aid the lift-off process and also protect the components mounted on the upper surface of the plastic substrate.
