Embodiment Construction

[0051] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the following embodiments are provided so that those skilled in the art can fully understand the present invention so that the following embodiments can be implemented in various forms. Accordingly, the present method should not be construed as limited to the embodiments set forth herein.

[0052] The following will refer to Figure 2 to Figure 13 The shape of the viewpoint generated by the naked-eye stereoscopic 3D image display device, its realization method, and the method of dynamically controlling the 3D image as the viewer moves are described.

[0053] This invention describes a method of dynamically providing 3D images only when the viewer is not significantly away from the designed optimal viewing distance. Hereinafter, an image control method when the viewer is significantly away from the sweet spot will be described in...

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...
