A backlight assembly includes a light source, a light-guiding plate and a diffusion sheet that includes a first bead layer on a lower surface of the diffusion sheet facing the light-guiding plate, and a second bead layer on an upper surface of the diffusion sheet. To improve image display quality, the hardness of the beads of the first bead layer facing the light guide plate are equal to or less than that of the light guide plate to prevent scratching of the light guide plate.

Disclosed is an X-ray detector and a method of manufacturing the X-ray detector. A cushion layer is interposed between a scintillator panel for converting X-rays into visual light and a lower substrate formed with a thin film transistor, a photoelectric conversion device. Thus, the lower substrate and the scintillator panel can be bonded to each other such that no air layer can be introduced between the lower substrate and the scintillator panel. Therefore, no air layer is introduced, and thus, it is possible to prevent the efficiency of light incident to the photoelectric conversion device from being lowered. Further, the cushion layer is employed such that the lower substrate and the scintillator panel can be separated and reused.

A power controlling device in a mobile communication system, and a method thereof. A base station calculates an average interference of N previous frames, and broadcasts the average interference to subscriber stations. The subscriber stations determine transmission power based on the average interference. Noise and Interference (NI) of frames within a section corresponding to a setting size is calculated (the frames may include a current frame) so an estimated interference is close to the interference generated in the frame in which the subscriber station actually transmits a signal. In addition, to more precisely estimate the NI, the NI of the current frame is compensated according to a value and is broadcast.

A photoelectric conversion device includes an intrinsic semiconductor layer, a first conductive type semiconductor layer disposed on a first side of the intrinsic semiconductor layer, and a second conductive type semiconductor layer disposed on a second side of the intrinsic semiconductor layer opposite the first side. The intrinsic semiconductor layer includes an amorphous semiconductor layer and a crystalline semiconductor layer including a plurality of crystals. A diameter of a crystal of the plurality of crystals is equal to or less than approximately 100 angstroms.

A method for detecting X-rays using an X-ray detector including an X-ray detecting part includes disposing a heat-circulating part adjacent to the X-ray detecting part. The X-ray detecting part includes light-detecting diodes. The method further includes detecting ambient temperatures of the light detecting diodes, circulating heat in the heat-circulating part based upon a result of the detecting the ambient temperatures of the light detecting diodes, increasing a uniformity of the ambient temperatures of the light-detecting diodes, and detecting X-rays irradiated into the X-ray detector.

Disclosed is a liquid crystal display apparatus in which a liquid crystal display module and cases are tightly combined. At least one protuberance formed on a top chassis of the liquid crystal display module combines at least one fixing portion formed on a portion of a rear case corresponding to the at least one protuberance. Also, a fixing protuberance formed on a portion of a front case is inserted into between the liquid crystal display module and the rear case, thereby preventing the liquid crystal display module from being moved. Therefore, the liquid crystal display module and the cases are tightly combined, and productivity of the liquid crystal display apparatus can increase by reducing the number of parts demanded for fabrication of the liquid crystal display module and the cases.
