  • Publication number: 20080240549
    Abstract: A method and an apparatus for controlling a dynamic depth of stereo-view or multi-view images. The method includes receiving stereo-view or multi-view images, generating a disparity histogram by estimating the disparity of two images corresponding to the received images and measuring the frequency of the estimated disparity, determining the disparity control amount of the stereo-view or multi-view images by convoluting the generated disparity histogram and a characteristic function, and rearranging stereo-view or multi-view input images by controlling parallax according to the control amount of parity.

  • Publication number: 20080186575
    Abstract: Provided is a 2D-3D switching display system that includes a backlight, a liquid crystal panel which forms a 3D image using light generated by the backlight, a viewing zone separation unit which separates an image formed by the liquid crystal panel into a left eye image and a right eye image, and a display panel which transmits light passing through the viewing zone separation unit.

  • Publication number: 20080174848
    Abstract: An image display apparatus includes a backlight unit where a reflection panel is installed at a bottom thereof, a polarization panel which transmits only light of a particular polarization direction of light emitted from the backlight unit, a polarization switch which changes the polarization direction of incident light, a birefringent element array which is formed by alternately arranging a plurality of first and second birefringent elements and changes the polarization direction of incident light to make the polarization directions of light passing through the first and second birefringent elements perpendicular to each other, a reflective polarizer panel which transmits only light of a particular polarization direction of the light passing through the birefringent element array and reflects light of the other polarization direction, a lens array which separates incident light into a first view zone and a second view zone, and a display panel which displays an image.

  • Publication number: 20080165296
    Abstract: A 2D/3D switchable display device includes a light source unit; a polarization switching unit for switching light from the light source unit to one of first polarized light and second polarized light, which is perpendicular to the first polarized light; a parallax barrier including slits and barriers that are alternately arranged, wherein the slits transmit incident light and the barriers transmit one of the first and second polarized light and reflect the other of the first and second polarized light; and a display panel for modulating light transmitted through the parallax barrier in response to an image signal to create an image. The 2D/3D switchable display device controls an electric signal applied to the polarization switching unit so that a 2D image and a 3D image are switched to each other.
