Description

Technical Field

[0001] The utility model relates to the technical field of stage performance engineering, in particular to a stage holographic display system with strong working stability for stage performance engineering. Background Art

[0002] Holographic projection technology is also known as virtual imaging technology. It achieves virtual imaging through some unique physical properties of light. There are three main virtual imaging technologies widely used today: rear projection, Pepper's Ghost and transparent display screens. Among them, Pepper's Ghost is the most widely used on large stages, and can provide the audience with a realistic 3D stereoscopic display effect. Its main principle is to use a screen that is parallel to the inside of the stage to project the content displayed on the screen onto a semi-transparent membrane with a polarization effect and an angle of forty-five degrees with the screen, so that part of the optical fiber can penetrate the semi-transparent membrane and the other part can reflect. When people's eyes receive the reflected light, due to the dark environment, they cannot see the semi-transparent membrane clearly and will mistakenly think that the image they see is displayed out of thin air, thus achieving the effect of holographic projection.

[0003] For example, the Chinese utility model provides "a portable holographic projection device", and its announcement number is: CN218413219U, which includes a storage box, and the two side walls on the top of the storage box are rotatably connected with a rotating shaft, and two "V"-shaped positioning grooves are provided on the outer wall of the rotating shaft, and a movable plate is fixed between the two rotating shafts, and four display screens are embedded on the surface of the movable plate. A holographic projection board is also bonded to the surface of the movable plate, and the holographic projection board is located between the four display screens. The holographic projection board is in an inverted cone shape. This portable holographic projection device is different from the prior art. The movable plate is flipped over so that the holographic projection board is in the storage cavity, thereby avoiding the problem that the projection board is easily contaminated with dust and affects the projection effect, and can improve the protection of the projection board. When the rotating rod is rotated to both sides of the bottom of the storage box, it can provide support to avoid the overall shaking during use and improve stability. If the rotating rod is rotated to the top of the storage box, it can be used as a handle for easy carrying.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the technology: during the use of the holographic projection device in the above patent, the device cannot be highly adjusted according to the use requirements, which leads to poor convenience in using the device and reduces the use effect of the display system. For this reason, we propose a stage holographic display system with strong working stability for stage performance engineering. Utility Model Content
