Abstract: Disclosed is a photonic crystal organic light emitting device. The device comprises a transparent substrate having a concavo-convex structure in an upper surface thereof, a transparent electrode layer formed on the transparent substrate, a hole conduction layer comprised of an organic EL material and formed on the transparent electrode layer, an electron conduction layer comprised of an organic EL material and formed on the hole conduction layer, and a cathode layer formed on the electron conduction layer. Here, a photonic crystal period due to the concavo-convex structure formed in the upper surface of the transparent substrate corresponds to a wavelength level of light generated at an interface between the electron conduction layer and the hole conduction layer. Therefore, a light extraction efficiency and a viewing angle are increased without degeneration of the image quality. Further, since the photonic crystal has an effective refractive value ranged between that of the transparent substrate and that of the transparent electrode layer, it has the same effect as in nonreflective coating, thereby simultaneously increasing the transmittance.

Abstract: PURPOSE: An inconsistency management method among contextual information in a situation recognition system and a device thereof are provided to keep the reliable context information inside the system by eliminating inconsistency of the contextual information from the situation recognition system. CONSTITUTION: An inconsistency descriptor generator(107) creates a context information inconsistency descriptor. A context information inconsistency manager(108) proceeds detection and removal of inconsistency of the context information. A context information inconsistency detector(110) analyzes the context information inconsistency descriptor. The context information inconsistency detector detects generation of inconsistency about the context information. A context information inconsistency remover(112) eliminates inconsistency of the context information.
