Disclosed are a single crystal wire and other single crystal articles, and a manufacturing method thereof. The method comprises the steps of: placing into a growth crucible at least one metal selected from the group consisting of gold, copper, silver, aluminum and nickel; heating and melting the metal placed in the growth crucible; growing a single crystal using metal crystal as a seed by Czochralski or Bridgman method; cutting the grown single crystal by electric discharge machining; and machining the cut single crystal and producing a wire or other articles such as a ring. In the method, the grown metal single crystal is cut into a disc-shaped piece by electric discharge machining. The piece is transformed into a single crystal wire or other articles by wire-cut electric discharge machining, and the single crystal wire can be used as a ring, a pendant, or a wire for high-quality cables for audio and video systems. Also, the single crystal formed into the disc-shaped piece by electric discharge machining can be used as a substrate and a target for deposition.

An autostereoscopic 3D image display device using time division is provided. The image display device includes a backlight, an image display panel, a controller, and a viewer position tracking system. The backlight includes a plurality of line sources which are disposed at certain intervals. The image display panel displays a 3D image. The controller controls the backlight and a viewing-point image of the image display panel. The viewer position tracking system determines pupil position of a viewer and transfers position information to the controller. The image display panel provides two or more viewing points. The line sources configure three or more line source sets that are separately driven. The controller adjusts a viewing-point width of a unit viewing point and the distance between adjacent viewing points to be 1.5 or more times the distance between both eyes of a viewer.
