Problems solved by technology

Holographic technology can produce very realistic spatial effects, but it requires high-resolution spatial light modulators and ultra-high-speed data processing systems in terms of dynamic display. These two factors greatly limit the progress of this technology, making it Not yet well into practical applications

Embodiment Construction

[0015] like figure 1 As shown, the splicing field of view stereoscopic three-dimensional display device includes a display screen array 1, a projection lens array 2, and a directional scattering screen 3 placed in sequence, wherein each display screen 4 in the display screen array 1 is directly in front of the projection lens array 2. Each projection lens 5 corresponds one-to-one and constitutes a projector array, and each projector 6 projects the respective display images of its corresponding display screen 4 onto the same position on the directional scattering screen 3 at the same time, and the projection lens 5 is composed of an aperture 7 and a It consists of several lenses, all the projection lenses 5 are vertically staggered in turn, and the lateral distance between two adjacent projectors 6 is the width of the aperture 7, and the apertures 7 in all the projection lenses 5 are spliced ​​and arranged laterally. In the splicing field of view stereoscopic three-dimensional ...

Abstract

The invention discloses a splicing view field stereoscopic three-dimensional display device and a method thereof. The device sequentially comprises a display screen array, a projection lens array anda directional diffuser screen; wherein each display screen and a projection lens arranged at right front thereof form a projector, and all the projectors are lengthways arranged by means of dislocation position and project images which are displayed corresponding to the display screen on the same position of the directional diffuser screen. The image respectively displayed by the each display screen in the splicing view field stereoscopic three-dimensional display method is spliced by one vertical bar image of the different viewing angles of a three-dimensional object, each vertical bar imageis projected to an original view angle by a developing lens, and the directional diffuser screen displays the images of the three-dimensional object with different view angles at traverse different directions. The invention has the advantage of being capable of generating three-dimensional images with high image distinguish ratio and high view distinguish ratio. Extreme fine view angle isolation can bring complete continues no-hop three-dimensional perception to observers.

Description

technical field [0001] The present invention relates to a three-dimensional display device and method, in particular to a stereoscopic three-dimensional display device and method for splicing fields of view. Background technique [0002] The difference between three-dimensional display and two-dimensional display is to bring visual depth perception to the viewer through various methods, so that it can naturally or unnaturally obtain the third-dimensional information in the picture. For the viewer, there is a difference between true three-dimensional and false three-dimensional (or quasi-three-dimensional). The development of 3D display technology has produced a large number of achievements today, which can be roughly divided into holographic 3D display, volumetric 3D display, and stereoscopic 3D display. Holographic technology can produce very realistic spatial effects, but it requires high-resolution spatial light modulators and ultra-high-speed data processing systems in ...
