  • Image displaying unit of a 3D image system having multi-viewpoints capable of displaying 2D and 3D images selectively
    Patent number: 7336326
    Abstract: A 3D image displaying unit in which 2D and 3D images are interchangeable. The 3D image displaying unit includes an image display panel which displays 2D or 3D images, and an optical plate which is provided behind the image display panel and refracts an incident light to the image display panel. Also, the 3D image displaying unit includes a first flat display device which displays a multi-viewpoint image in a case where the 3D image is displayed, and is transparent in a case where the 2D image is displayed, an optical plate which refracts lights that are incident from the first flat display device and provides parallax in a predetermined direction, and a display unit which provides the lights that pass through the optical plate with a parallax in the vertical direction to a parallax provided by the optical plate in the case where the 3D image is displayed, and displays the corresponding 2D image in the case where the 2D image is displayed.
