  • Publication number: 20120026159
    Abstract: An active-type stereographic image display apparatus includes an image display unit; a touch sensing unit to sense a touch position through a first transparent electrode layer and a second transparent electrode layer that are arranged to cross with each other, and to separate an image output from the image display unit through a lens array into a first eye image and a second eye image based on a refractive index of light; and a lens driving control unit to control a focal length by controlling the lens array. The method for driving the active-type stereographic image includes displaying a stereographic image comprising a first eye image and a separate second eye image, sensing a touch position of a user input, separating an image output into a first eye image and a second eye image, and controlling a focal length provided by a lens array.

  • Publication number: 20120026112
    Abstract: Provided are a stereographic image display apparatus and a manufacturing method thereof. The stereographic image display apparatus includes an image display unit and a touch sensing unit which is positioned on the image display unit and is configured to interpose a lens array between a first transparent electrode layer and a second transparent electrode layer. The manufacturing method of the stereographic image display apparatus includes: allowing a transparent conductive material to be deposited on both surfaces of a lens array; forming first and second transparent electrode layers by etching the transparent conductive material deposited on the both surfaces of the lens array thereby generating a touch sensing unit; and adhering the touch sensing unit to an upper surface of an image display unit.
