Circular screen type 360-degree panoramic holographic projection display device

Abstract

The invention relates to the related technical field of projection display, in particular to a circular screen type 360-degree panoramic holographic projection display device. The device comprise a projection display instrument body. A clamping frame is slidably connected to the surface of a connecting base. A gear sleeve is adhered to the surface of the light guide mirror. Gears are meshed with the surfaces of the gear sleeves. A filter lens is extruded on the surface of the light filtering liquid bag body. A connecting plate is adhered to the surface of the filter lens. The connecting plateis slidably connected to the surface of the threaded rod. The third motor is screwed on the inner wall of the projection mirror. The beneficial effects are that: when processing projected content, a third motor is adjusted counterclockwise to enable the filter lens to be separated from the light filtering liquid bag body, the filter liquid bag body is kept in a lightproof state, and the projectioncontent can be processed at the moment. When the device is used, the third motor is adjusted clockwise, and the filter lens is extruded on the surface of the light filtering liquid bag body, so thatthe light filtering liquid bag body is in a light-transmitting state, the projected definition is improved, the use quality of the holographic projector is further guaranteed, and the holographic projector is suitable for popularization.

Description

technical field [0001] The invention relates to the related technical field of projection display, in particular to a ring-screen 360° panoramic holographic projection display device. Background technique [0002] Holographic projection technology is a kind of 3D technology. It originally refers to the technology of using the principle of interference and diffraction to record and reproduce the real three-dimensional image of objects. Later, with the guidance of science fiction movies and commercial propaganda, the concept of holographic projection gradually extends to stage performances and exhibitions. In commercial activities such as exhibitions, the holography we usually know is often not a holographic projection in the strict sense, but a kind of holographic projection technology that uses methods such as Pepper's phantom and edge blanking to achieve 3D effects, but it is generally used for The holographic projector for holographic projection still has the following dis...

Problems solved by technology

[0003] 1. When the holographic projector is in use, it is generally fixed on the mounting frame by means of screws and bolts, and then the mounting frame is fixed at the corresponding position for use to complete the installation of the holographic projector. The operation is complicated, time-consuming and laborious. It is necessary to manually remove the screws one by one, which is inconvenient to install and disassemble the holographic projector;

[0004] 2. The mounting frame used for fixing the holographic projector can only adjust the horizontal angle during use, and is used to project to a single position. When it is necessary to project to other angles, it is necessary to change the installation angle of the holographic projector. It is complicated and cannot realize the multi-angle rotation of the holographic projector, and the projection angle cannot be changed at the same time, which cannot meet the actual use requirements;

[0005] 3. Before projecting through the holographic projector, it is necessary to preprocess the projected content and projection angle. This work generally needs to be done in a concealed manner. Usually, the holographic projector is turned off, and the holographic projector is turned on after processing the projected content angle and degree. , the operation is complicated, it is not convenient to use, and at the same time, it is projected through a single projection mirror, and the projected clarity is poor
