An organic light emitting display device is provided to avoid color change due to a viewing direction. The organic light emitting display includes a light compensation layer having a refractive index different than that of an insulating layer. The organic light emitting display may be disposed at the side to which light emitted from an organic light emitting layer is entered to change the path and phase of light, thereby coinciding cavity peak phases for each wavelength of white light emitted from an organic light emitting unit.

A multi-level memory device includes an insulating layer having an opening therein, and a multi-level cell (MLC) formed in the opening that has a resistance level varies based on the data stored therein. The MLC is configured to have a resistance level that varies as write pulses having the same pulse height and different pulse widths are applied to the MLC.

A face recognition system based on adaptive learning includes a specific person detection and tracking unit for detecting and tracking a specific person from a moving image. A facial feature extraction unit extracts a plurality of facial feature vectors from the detected and tracked specific person. A face recognition unit searches for a given registration model by comparing the extracted facial feature vectors with facial feature vectors of the registration models previously stored in a user registration model database. A learning target selection unit selects a facial feature vector to be added to a record of the given registration model from among the extracted facial feature vectors. A registration model learning unit adds and updates the selected facial feature vector to the record of the given registration model.

A chip light emitting diode having a wide viewing angle, and a fabrication method thereof. The chip light emitting diode has a resin package sealing a light emitting chip which has at least one curved projecting part. The curved projecting part has a cross section which is substantially semicircular, or substantially or partially elliptical or parabolic. The curved projecting part preferably has a cross section which is comprised of a plurality of straight lines, an angle being formed between adjacent lines. The cross section is elongated to form a cylindrical outer surface of the resin package.

A printed circuit board (PCB) has a multi-layered substrate including a plurality of signal lines and a ground voltage plate disposed below the signal lines and by which a common ground voltage is applied to the signal lines, a heat sink disposed on the multi-layered substrate, and thermal interface material interposed between the signal lines and the heat sink to transfer heat from the multi-layered substrate to the heat sink. The heat sink thus dissipates the heat generating from the multi-layered substrate and along with the ground voltage plate suppresses electromagnetic interference of signal transmitted through adjacent ones of the signal lines. The thermal interface material also serves in the design phase as a means to tune the impedance of the signal lines.

The present invention relates to a side illumination lens and a luminescent device using the same, and provides a body, a total reflection surface with a total reflection slope with respect to a central axis of the body, and a linear and/or curved refractive surface(s) formed to extend from a periphery of the total reflection surface; and a luminescent device including the lens. According to the present invention, a lens with total internal reflection surfaces with different slopes, and a linear and/or curved refractive surface(s) allows light emitted forward from a luminescent chip to be guided to a side of the lens. Further, a linear surface(s) formed in a direction perpendicular or parallel to a central axis of a lens and a curved surface are formed on an edge of the lens so that a process of fabricating the lens is facilitated, thereby reducing a defective rate and fabrication costs of the lens.
