Abstract: Provided is a 3D image display apparatus, which configures a light path such that light sources radiated from at least two projection optical systems pass through any one point (or nodal point) formed before the imaging position and forms a viewing zone having at least two viewing points at each observation position. Thereby, fixing a ratio of a degree of overlap (crosstalk) between neighbor viewing zones according to each depth sense (or observation distance) behind the imaging position, establishing a 3D viewing environment suitable for an observer, and enabling the observer to view a multi-view and super multi-view image. In addition, by merging the adjacent viewing points within one viewing zone, it is possible to minimize an area in which the viewing zones are overlapped and uniformize the intensity of light representing an image.

Abstract: Provided is a three-dimensional (3D) image display apparatus using laser beam scanning (LBS) projection optical systems. The 3D image display apparatus includes a plurality of LBS projection optical systems arrayed in horizontal and vertical directions, an input unit through which a 3D image signal is input, and an image signal controller configured to distribute the 3D image signal input through the input unit to the LBS projection optical systems. Each of the arrayed LBS projection optical systems has a beam-projection center point for outputting light to an outside of the LBS projection optical system, and an image projected from the beam-projection center point is a horizontal-parallax image based on the beam-projection center point.
