Embodiment 1
[0025] See figure 1 , figure 1 It is a schematic structural diagram of a volumetric three-dimensional display device provided by the present invention.
[0026] Specifically, the volumetric three-dimensional display device includes: a high-speed projection device, a synchronous control device, and a three-dimensional dimming film structure.
[0027] The high-speed projection device faces the stereoscopic light-adjusting film structure and is used for projecting a two-dimensional image with depth information to the stereoscopic light-adjustable film structure, wherein the projection end of the high-speed projection device faces the stereoscopic light-adjustable film structure.
[0028] Preferably, the projection direction of the high-speed projection device is perpendicular to the structure of the three-dimensional light-adjusting film, which avoids the defect that the image display is unclear due to the offset of the projection angle.
[0029] In a specific embodiment of the...

The invention relates to a volume three-dimensional display device and a control method thereof, comprising: a high-speed projection device, a synchronous control device and a stereo dimming film structure; The high-speed projection device is opposed to a stereo dimming film structure for projecting a two-dimensional image having depth information onto the stereo dimming film structure, wherein the projection end of the high-speed projection device faces the stereo dimming film structure; A synchronization control device electrically connecting the high-speed projection device and the stereoscopic dimming film structure for identifying depth information of a two-dimensional image and transmitting a corresponding dimming signal to the stereoscopic dimming film structure; The stereoscopic dimming film structure is used for adjusting the transmittance of the electrically controlled dimming film according to the dimming signal. The device provided by the invention utilizes a stereoscopic dimming film structure to express three-dimensional image information, overcomes the defect that the traditional volume three-dimensional display device can only see three-dimensional images from the front of the display and the observation angle is single, improves the three-dimensional display effect and the viewing experience of a user, and can be widely applied to three-dimensional display.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a volumetric three-dimensional display device and a control method thereof. Background technique [0002] In recent years, with the rapid development of computer software, hardware and multimedia industry, computer stereo vision system has increasingly become the mainstream development direction of the next generation display field. Compared with the traditional two-dimensional display technology, three-dimensional display can display the depth, layering, spatial position and other information of objects, which is more in line with people's daily binocular observation habits and can bring better viewing and immersive experience. It has been more and more widely used in military, medical, aviation, advertising, entertainment and other industries. [0003] At present, relatively mature 3D display technologies include spectroscopic 3D glasses, automatic spectroscopic 3...
