  • AREA-SELECTIVE EMTHOD FOR FORMING THIN FILM BY USING NUCLEAR GROWTH RETARDATION
    Publication number: 20240068091
    Abstract: Disclosed is a method of forming an area-selective thin film, the method comprising supplying a nuclear growth retardant to the inside of the chamber in which the substrate is placed, so that the nuclear growth retardant is adsorbed to a non-growth region of the substrate; purging the interior of the chamber; supplying a precursor to the inside of the chamber, so that the precursor is adsorbed to a growth region of the substrate; purging the interior of the chamber; and supplying a reaction material to the inside of the chamber, so that the reaction material reacts with the adsorbed precursor to form the thin film.

  • 3D display system
    Patent number: 9055289
    Abstract: Provided is a three-dimensional (3D) display system. The 3D display system synthesizes a 3D image and position information data of an observer obtained through a camera with an optimal viewing area image with respect to horizontal and vertical directions of a display panel in a 3D space, and displays the synthesized image on the display panel such that the observer can visually know an optimal viewing area. Accordingly, the 3D display system enables the observer to visually check the optimal viewing area with ease and induces the observer to move to a position in the optimal viewing area.
