DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0010] See also Figure 1 The utility model provides a technical solution, a floating imaging party history education display device, including a display cabinet 1, a floating imaging system 4, an industrial computer 3 and a sound system. The display cabinet 1 is divided into three layers from bottom to top. The industrial computer 3 and the sound system are placed on the lower layer of the display cabinet 1, the floating imaging system 4 is placed on the middle layer, and the floating imaging area 8 is arranged on the upper layer; the sound system includes a digital audio decoder 21 and a speaker 22. The digital audio decoder 21 has built-in audio materials for party lessons, and is connected to the industrial computer 3 through an audio line to achieve synchronous audio playback. The speaker 22 is installed inside the display cabinet 1 and is arranged symmetrically on the left and right.

[0011] The floating imaging system 4 includes a semi-transparent and semi-reflective mirror 41, a display screen 42 and a plano-convex lens 43. The display screen 42 is vertically arranged at the rear of the display cabinet 1; the semi-transparent and semi-reflective mirror 41 is installed in front of the display screen 42 at a 45-degree angle to the lower bottom plate; the plano-convex lens 43 is fixedly arranged above the semi-transparent and semi-reflective mirror 41.

[0012] Furthermore, the semi-transparent and semi-reflective mirror 41 is made of optical glass with high light transmittance, and a reflective film is provided on one side close to the display screen 42 and an anti-reflection film is provided on the other side. The reflectivity of the reflective film is 30-40%, and the visible light transmittance of the anti-reflection film is 40-50%. The size corresponds to the display screen 42.

[0013] Furthermore, a hatch is provided on the front of the display cabinet 1, the lower layer of the display cabinet 1 is a box structure made of metal or wood material, and the four walls of the middle and upper layers are transparent protective plates 11, which are made of high-transparency glass or acrylic plates.

[0014] Furthermore, the display screen 42 adopts an ultra-bright liquid crystal screen or an LED screen with a brightness of 1500-2000nit.

[0016] The working principle of this device is as follows: the industrial computer 3 plays the party history video material in the digital audio decoder 21 and displays it on the high-brightness display screen 42. After the parallel light 5 emitted by the screen is reflected by the semi-transparent mirror 41, the reflected light 6 forms a floating virtual image above the semi-transparent mirror 41 under the convergence of the plano-convex lens 43. Since the semi-transparent mirror 41 has a certain light transmittance, when the observer watches from the front, the line of sight can see the virtual image suspended in the air through the semi-transparent mirror 41. The virtual image is presented as a three-dimensional image that is the same as the display content and suspended in the air, so that the viewer can get an immersive floating imaging effect. At the same time, the plano-convex lens 43 can optimize and adjust the focusing distance and clarity of the imaging; at the same time, the industrial computer 3 is responsible for the storage and playback of the video, and synchronizes with the sound system to create an interactive experience of sound and picture. The transparent protective plate 11 can prevent dust and foreign matter from affecting the imaging quality; the entire device has a compact structure and is installed in a vertical display cabinet 1. It can be flexibly arranged according to needs and has strong environmental adaptability.
