Stereoscopic three-dimensional display based on multi-screen splicing

Abstract

The invention discloses a stereoscopic three-dimensional display based on multi-screen splicing. The stereoscopic three-dimensional display comprises a two-dimensional display array, a projection lens array, an aperture array and a directional scattering screen. By utilizing a two-dimensional display pixel region segmentation mode and ensuring each display region of the display array to form a projector together with an aperture and a projection lens which is directly in front of the region, all projectors are staggered in vertical direction and project the images corresponding to the display regions to a same position on the directional scattering screen so as to form an image in front of an arc-shaped screen; and the images displayed in each display region are spliced by the images of a three-dimensional object from different visual angles according to a specific segmentation and recombination method. The stereoscopic three-dimensional display provided by the invention has the advantages of achieving high image resolution and high visual angle resolution and realizing observation of an exquisite three-dimensional image with a horizontal parallax. Compared with the single naked-eye display, stereoscopic three-dimensional display provided by the invention has the advantages that the multi-screen splicing settings ensures that the extension of visual angles is realized, and the spatial scale and viewing range of the three-dimensional images are increased.

Description

technical field [0001] The present invention relates to a three-dimensional display device, in particular to a stereoscopic three-dimensional display device based on multi-screen splicing. Background technique [0002] Display technology is developing towards high-definition, three-dimensional panoramic display. The difference between three-dimensional display and traditional two-dimensional display is to bring visual depth perception to the viewer through various methods, so that it can naturally and unnaturally obtain the third-dimensional information in the picture. Many 3D display technologies at home and abroad can generally be divided into two types: holographic 3D display and non-holographic 3D display. Holographic three-dimensional display is known as the ideal three-dimensional display method in the future because it is a true three-dimensional information recording and display, but it requires a high-resolution spatial light modulator and an ultra-high-speed data ...

AI Technical Summary

Problems solved by technology

[0003] Most of the projection naked-eye three-dimensional display devices that have been developed so far have complex structures and require a large number of projectors and control circuits, so they lack specific practical applications.

Moreover, the image displayed by a single naked-eye stereoscopic display has low resolution, few and discontinuous viewing angles, and insufficient depth perception, which make it lack of innovation in the field of virtual reality.
