[0025] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0026] Example 1

[0027] refer to Figures 1-4 , a portable holographic opera display device, comprising a box body 1, a box cover 4 and a transparent panel 6;

[0028] Storage slots 2 are provided on both sides of the top of the box body 1. Supports 3 are foldably installed on both sides of the two sets of storage slots 2. Slots 12 are provided at the four corners of the bottom of the box cover 4. The tops of the respective sets of support 3 are inserted into the respective sets of slots 12. The box cover 4 is installed on the top of the box body 1 through the support 3. A panel storage drawer 9 is movably installed at the bottom of the box body 1.

[0029] Among them, the bottom sides of the pillar 3 are provided with a rotating shaft 15, and the pillar 3 is movably installed in the receiving slot 2 through the rotating shaft 15;

[0030] Secondly, buckles 8 are installed on the front and rear outer walls of the box body 1 and the front and rear outer walls of the box cover 4;

[0031] In addition, the panel storage drawer 9 is movably installed in the box body 1 through a guide rail, and a handle 10 is fixedly installed on the outer wall of the panel storage drawer 9;

[0032] It is worth mentioning that a sealing strip 14 is fixedly embedded around the bottom of the box cover 4, which can achieve a sealing effect when the box cover 4 and the box body 1 are closed, thereby achieving dust and water resistance;

[0033] In this embodiment, the panel storage drawer 9 can be pulled out from the box body 1 by the handle 10, and the transparent panel 6 can be taken out. Then, the pillar 3 can be unfolded from the storage slot 2 through the rotating shaft 15, and the top of the pillar can be inserted into the slots 12 at the four corners of the bottom of the box cover 4, so that the box cover 4 is installed above the box body 1. The box body 1 and the box cover 4 can be fixed by the buckle 8 to ensure the structural stability of the device during carrying or use. When storing, the above steps are reversed, the transparent panel 6 is placed in the panel storage drawer 9, the pillar 3 is folded, the box cover 4 is covered and the buckle 8 is fastened.

[0034] Example 2

[0035] refer to Figures 1-3 , a portable holographic opera display device, comprising a box body 1, a box cover 4 and a transparent panel 6;

[0036] There are four groups of transparent panels 6. A first rectangular slot 11 is opened in the center of the top of the box body 1, and a second rectangular slot 13 is opened at the bottom of the box cover 4. The upper and lower ends of the transparent panels 6 are respectively inserted into the second rectangular slot 13 and the first rectangular slot 11. The four groups of transparent panels 6 are assembled between the box body 1 and the box cover 4 in an inverted cone shape.

[0037] A display screen 5 is embedded and installed on the top of the box body 1 and around the first rectangular slot 11;

[0038] Secondly, a player 7 is embedded in the side wall of the box 1, and the player 7 is connected to the signal of each group of display screens 5;

[0039] In addition, the transparent panel 6 is made of a material with high light transmittance and wear resistance, and the surface is coated with an anti-fingerprint coating;

[0040] In this embodiment, the upper and lower ends of the four groups of transparent panels 6 are respectively inserted into the second rectangular slot 13 and the first rectangular slot 11 so that they are assembled in an inverted cone shape. The holographic opera content to be played is then selected through the player 7, and the player 7 transmits the signal to the display screen 5. The display screen 5 displays relevant images or videos around the first rectangular slot 11 on the top of the box 1. The transparent panel 6 can clearly display the internal holographic image effect due to its high light transmittance and wear resistance and the anti-fingerprint coating on the surface. The audience can watch the holographic opera display combined with the content of the display screen 5 through the transparent panel 6.

[0041] Working principle: First, the player 7 stores or can read files containing opera audio, video and other data. When the user starts the device, the player 7 decodes and processes the opera data according to the user's operating instructions or the preset playback order. The processed audio signal is output to the display screen 5 embedded around the top of the box 1 through a specific audio transmission line. After receiving the video signal, the display screen 5 presents the image content of the opera in a visual form through its internal display driving circuit and pixel array. These images can be the performance scenes of opera actors, stage backgrounds, special effects pictures, etc. They are displayed around the first rectangular slot 11 in the center of the top of the box 1, forming a visual encirclement. When light passes through the transparent panel 6, combined with the specific optical design that may involve a combination of optical principles such as reflection, refraction and diffraction, a three-dimensional visual effect is formed in the inverted cone space surrounded by the transparent panel 6, as if the opera scene is presented in a virtual three-dimensional space. The role of the pillar 3 is not only It connects the box body 1 and the box cover 4 to form a stable structure, provides mechanical support for the entire display device, ensures that each component is relatively fixed in the correct position, and ensures the normal operation of optical and electronic components. At the same time, its foldable design facilitates the storage and carrying of the device when not in use, and improves the portability of the device. The panel storage drawer 9 provides a safe storage space for components such as the transparent panel 6. In the stored state, the transparent panel 6 can be neatly placed in the drawer to avoid damage such as scratches and collisions from the outside. When needed, the user can easily pull out the drawer through the handle 10, take out the transparent panel 6 for installation, which improves the convenience of device use and the efficiency of component management. The buckle 8 can be used in the process of closing and carrying the device. The buckle 8 tightly fixes the box body 1 and the box cover 4 together to prevent internal components from shifting or being damaged due to shaking, collision, etc. At the same time, it also prevents dust, debris, etc. from entering the device when not in use, affecting the performance and service life of the device.

[0042] It is understood that the player and display screen of the present invention can be driven by an external power cord and can be programmably controlled by a main control system, and the control principles are achievable using existing control technology. The player and display screen are not limited to a single model and can be any commercially available model suitable for the present invention.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
