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.

Abstract: Disclosed are a system and method for measuring viewing zone characteristics of an autostereoscopic three-dimensional (3D) image display device. The system for measuring viewing zone characteristics of the autostereoscopic 3D image display device includes at least one image sensor that is provided on a front side of the image display device, and measures characteristics of luminance distribution of viewpoint images in a depth direction (Z-direction) formed from at least two local areas which are designated in advance in a horizontal direction (X-direction) of the image display device, and a determination unit that determines, as an optimum viewing distance (OVD), a position of the image sensor corresponding to a depth direction (Z-direction) having a horizontal direction (X-direction) minimum deviation of a center position of luminance distribution of light generated from the same viewpoint image of each of the at least two local areas by analyzing the characteristics of luminance distribution on an X-Z plane measured from the image sensor.
