    Abstract: Provided is a driving method for a beam steering device having a metasurface optical phased array, the beam steering device includes a nano-antenna, a conductor, and an active layer arranged therebetween. The driving method includes comparing a first voltage to be applied to a first electrode of one of the nano-antenna and the conductor, with a second voltage applied immediately before the first voltage, and applying a correction voltage the first electrode of the other of the nano-antenna and the conductor and then applying the first voltage. The correction voltage is applied to the first electrode and has an electrical polarity different from an electrical polarity of the second voltage.

    Abstract: A radiation detector may include: a common electrode; a thin film transistor (TFT) array; a photoconductor material layer disposed between the common electrode and the TFT array; and a diffusion stop layer, disposed between the common electrode and the TFT array, on a location corresponding to a connecting portion where the common electrode is connected to a bias voltage supply source, wherein the diffusion stop layer prevents a metal included in the connecting portion from diffusing to the photoconductor material layer.

    Abstract: A method of manufacturing an X-ray detector includes: applying a mask having an opening on a substrate on which a plurality of charge detection units are positioned; filling the opening with a paste including a photoelectric conversion material that absorbs X-rays to generate charges; and forming a photoconductive layer from the paste by separating the mask from the substrate. A thickness of the paste within the opening is thicker in an area adjacent to at least one edge among edges of the opening than in areas around other edges.

    Abstract: An image display device includes a main light source configured to emit a first light; a display panel configured to modulate the first light to add image information to the first light; a holographic optical element (HOE) configured to diffract the first light emitted from the display panel to make the first light travel to a first region to generate a main image; a first optical system provided on a traveling path of the first light between the main light source and the HOE, the first optical system being configured to change the traveling path of the first light to be incident on the HOE along a first path; an auxiliary light source configured to emit a second light; and a second optical system provided on a traveling path of the second light, the second optical system being configured to change a traveling path of the second light to be incident on the HOE along a second path different from the first path.
