Problems solved by technology
However, the viewing angle of this design is limited by the polarization angle of the diffusing screen. When the observer's head is tilted, the images of the left and right eyes cannot be effectively distinguished, so that stereoscopic images cannot be observed.

Embodiment Construction
[0038] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.
[0039] Certain terms are used in the description and claims to refer to particular elements. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same element by different terms. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Include" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to".
[0040] see figure 1 As shown, a schematic structural diagram of an embodiment of the stereoscopic display device of the present invention is disclosed, including: a first driving unit 100 , a first base 110 , a first scattering unit 120 ,...

The invention provides a stereoscopic display device. The stereoscopic display device comprises a first driving unit, a first base, a first scattering unit, a first projection unit and a processing unit, wherein the first base is arranged on the first driving unit; a first end of the first scattering unit is arranged on the first base; the first driving unit rotatably drives the first scattering unit to rotate so as to form a first space; the first scattering unit comprises a first number of scattering bodies which are used for scattering projected light; the first projection unit is arrangedon a second end side of the first scattering unit, and is used for projecting a first light beam towards the first scattering unit; the processing unit is electrically connected to the first driving unit and the first projection unit, is used for controlling the first driving unit to rotate, and controls the first projecting unit to project the first light beam to the scattering bodies, so that adisplayed image is formed in the first space formed by the first scattering unit through rotation. By the provided stereoscopic display device, an observer can observe a real stereoscopic display image on the outside of the first space at an optional angle.
Description
technical field [0001] The invention relates to the field of display, in particular to a stereoscopic display device with visual persistence effect generated by rotating a light-emitting element. Background technique [0002] In recent years, with the rapid development of video display technology, the development of technology for displaying stereoscopic video is being advanced, and it is widely used in entertainment, medical care, electronic catalogs, advertisements, and the like. [0003] In the prior art, the light beam is usually projected to an inclined mirror that can be rotated at high speed, and the mirror projects the reflected light onto a cylindrical transmission screen parallel to the rotation axis, and the transmission screen can control the divergence angle of the transmitted light , so that the left and right eyes of the observer can see images of different viewing angles, forming a panoramic stereoscopic image. However, the viewing angle of this design is li...
