Abstract

The invention provides a three-dimensional display device. The three-dimensional display device comprises a cabinet beam splitter, a spotlight and video playing equipment, wherein the cabinet beam splitter comprises five semitransparent optical mirrors which are combined to form an inverted-pyramid-shaped semitransparent space. A square projection hole is formed in each of bottom spliced positions of the lower four optical mirrors of the cabinet beam splitter, the spotlight is arranged on the upper side of the cabinet beam splitter, the video playing equipment is disposed on the lower portion of the cabinet beam splitter, and light rays of the video playing equipment can penetrate the projection holes to enable a dynamic image to suspend in the center of the space of the cabinet beam splitter. The invention further provides a display method of the three-dimensional display device. The three-dimensional display device and the display method thereof have the advantage that people can attain visual impact and strong scene feeling brought by 3D (three-dimensional) special effects heartily and freely without wearing any 3D glasses.

Description

technical field [0001] The present invention relates to the technical field of projection imaging, in particular to a three-dimensional display device and a display method thereof. Background technique [0002] The existing three-dimensional display method achieves the three-dimensional display effect through a naked-eye 3D display or by wearing 3D glasses. Both methods are realized by using the principle of visual difference between two eyes. [0003] Among them, 1. Naked-eye 3D display light barrier 3D technology: the realization method is to use a switch liquid crystal screen, polarizing film and polymer liquid crystal layer, and use the liquid crystal layer and polarizing film to produce a series of vertical stripes with a direction of 90°. These stripes are tens of microns wide, and the light passing through them forms a pattern of vertical thin stripes, called "parallax barriers." This technology utilizes the parallax barrier placed between the backlight module and th...
