Abstract

The invention discloses a multi-view desktop type three-dimensional display device, comprising two projector arrays which are symmetrically distributed, two longitudinal diffusion screens and a desktop structure, wherein the first projector array is placed at one side of the first longitudinal diffusion screen; the second projector array is placed at one side of the second longitudinal diffusion screen; the desktop can be a square-hole-shaped desktop or middle-opened L-shaped desktop; the two longitudinal diffusion screens are embedded in the desktop structure to form a V shape, a right angle, a trapezoid or an arc; and the two projector arrays project images to the center of the desktop through the corresponding diffusion screens. The multi-view desktop type three-dimensional display device provided by the invention has the advantages that high image resolution and high view resolution can be generated and exquisite transverse-parallax three-dimensional images can be observed in large field ranges of two sides or one side of the desktop. Through the structure of embedding in the desktop, the suspension effect of the three-dimensional images can be realized. Relative to a single naked-eye stereoscopic display, the split joint of the three-dimensional images can be realized via the setting of multi-projection so that the space scale of the three-dimensional images is greatly increased.

Description

technical field

[0001] The invention relates to a three-dimensional display device, in particular to a multi-view desktop three-dimensional display device. 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 processing system in terms of dyn...
