Abstract

The present invention relates to a 3D image display device and includes an image display panel for displaying a 3D image, a control unit for controlling a viewpoint image, and a viewer position tracking system for determining the position of a viewer's pupil and transmitting positional information to the control unit, wherein the image display panel provides multiple viewpoints such as four or more viewpoints, and the intersection of the field of view for any one of the multiple viewpoints with the field of view of an adjacent viewpoint is at least 85% of the maximum brightness of one viewpoint.

Description

technical field [0001] The present invention relates to a naked-eye stereoscopic three-dimensional (3D) image display device, and more particularly, to a device that can dynamically minimize crosstalk at the pupils of the viewer and minimize the 3D image even if the viewer moves by operating as follows The luminance-changing 3D image display device of the , wherein the operation includes: flattening a viewing area luminance distribution of a viewpoint image generated by arranging a parallax barrier, a lenticular lens, or a line light source as an optical plate for forming the viewing area, The flattened adjacent viewpoint viewing areas are overlapped, the viewer's position is tracked in real time, viewpoint images are provided at the viewpoint of the viewer's pupils, and the adjacent viewpoint images are removed. Background technique [0002] Glasses-free stereoscopic 3D image display devices are classified into a type using an optical plate such as a lenticular lens or a pa...
