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 present invention provides a stereoscopic display device, comprising: a first driving unit, a first base arranged on the first driving unit, a first scattering unit whose first end is arranged on the first base, and driven by a first The unit rotates to drive the first scattering unit to rotate to form the first space; the first scattering unit includes a first number of scattering bodies to scatter the projected light; the first projection unit arranged on the second end side of the first scattering unit, used to project a first light beam toward the first scattering unit; and, a processing unit electrically connected to the first driving unit and the first projection unit, used to control the rotation of the first driving unit and control the first projection unit Projecting the first light beam to the scattering body to form a display image in the first space formed by the rotation of the first scattering unit. With the stereoscopic display device provided by the present invention, observers can observe more realistic stereoscopic display images from any angle outside the first space.
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...
