For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0026] like Figures 1 to 3 As shown, a spherical naked-eye 3D holographic display device provided in this embodiment can realize 360-degree 3D holographic display, allowing users to watch from multiple directions, with good holographic display effect, and can improve viewing experience. The holographic display device of this embodiment mainly includes a rotating base 1 and a display component 2 connected to the bottom of the rotating base 1, wherein a motor component and a power supply component are installed inside the rotating base 1, and the power supply component is electrically connected to the motor component and the display component 2 respectively, so that the display component 2 can rotate under the drive of the motor component and display under the action of the power supply component, thereby enabling the display component 2 to realize 3D holographic display under the action of the rotation scanning display technology (POV) and the human eye retention principle.

[0027] The power supply assembly and the motor assembly of this embodiment are arranged in sequence from top to bottom, wherein the power supply assembly is connected to an external power supply cable to supply power to the motor assembly and the display assembly 2. In order to avoid the influence of the power supply cable when the motor assembly rotates, the power supply assembly and the motor assembly of this embodiment can be electrically connected through an electric slip ring or wireless power supply, so that the motor assembly drives the display assembly 2 to rotate to realize holographic display, and the power supply cable can be prevented from being damaged.

[0028] Specifically, Figure 1 and Figure 2 As shown, in order to enable the display component 2 to achieve a 360-degree 3D holographic display, the display component 2 of this embodiment includes a circular FPC board 21 and a plurality of LED lamp beads 22 equidistantly arranged and mounted on the outer surface of the circular FPC board 21, wherein the circular FPC board 21 of this embodiment is longitudinally connected to the bottom of the rotating base 1, and at the same time, the circular FPC board 21 is provided with a plurality of driver IC chips for controlling the light emission of the LED lamp beads 22, so that when the rotating base 1 is started, the circular FPC board 21 can rotate to form a sphere under the drive of the rotating base 1, and at the same time, the driver IC chip mounted on the circular FPC board 21 controls the LED lamp beads 22 to emit light at a set frequency, so that the surface of the sphere is illuminated and displayed, and then the 360-degree holographic display effect of this embodiment is achieved under the action of the rotating scanning display technology (POV) and the principle of human eye retention, which is convenient for users to watch from all directions.

[0029] The number of the circular FPC board 21 in this embodiment can be one or more. Figure 1 As shown, in one embodiment, the circular FPC board 21 is set as one, and the top of the circular lamp board is connected to the rotating base 1, so that when the rotating base 1 drives the circular FPC board 21 to rotate, the circular FPC board 21 can rotate to form a sphere so that the LED lamp beads 22 can achieve 360-degree 3D holographic display. However, in order to ensure the display effect of the 3D holographic display, the rotation speed required for a single circular FPC board 21 is relatively high, which makes the circular FPC board 21 easy to deform and the motor cost is relatively high. Therefore, in other embodiments, the circular FPC board 21 can also be set as multiple strips, including but not limited to two, three, four, five, etc.

[0030] like Figure 3As shown, in another embodiment, the circular FPC boards 21 are arranged in two pieces, the tops of the two circular FPC boards 21 are connected to the rotating base 1, and the bottoms of the two circular FPC boards 21 are vertically cross-connected. When the rotating base 1 is started, the two circular FPC boards 21 can be driven to rotate together to form a sphere, thereby making the LED lamp beads 22 attached to the surfaces of the two circular FPC boards 21 display a 360-degree 3D holographic picture. In this embodiment, by arranging two cross-arranged circular FPC boards 21, the number of LED lamp beads 22 is increased, thereby reducing the requirement for the circular FPC board 21 to rotate into a sphere, which can reduce the probability of deformation of the circular FPC board 21, and at the same time, the requirements for the motor are also reduced.

[0031] In order to ensure the display effect when multiple circular FPC boards 21 are set, the multiple circular FPC boards 21 of this embodiment can be cross-arranged at equal angles so that the spacing between the LED lamp beads 22 on different circular FPC boards 21 is the same, thereby improving the stability and continuity of the display of the LED lamp beads 22 when the circular FPC boards 21 rotate under the drive of the rotating base 1, and the display is more uniform, easy to control, and easy to achieve a good display effect.

[0032] This embodiment not only effectively improves the display stability and continuity of the holographic image of this embodiment by setting a plurality of circular FPC boards 21 that cross at equal angles, but also reduces the rotation speed requirement of the display component 2, thereby reducing the image breakage or distortion problem caused by the excessive rotation speed of the circular FPC board 21, optimizing the display effect of the holographic image, and greatly enhancing the user's viewing experience.

[0033] like Figure 1 and Figure 3 As shown, the circular FPC board 21 of this embodiment is formed by splicing two symmetrically arranged first arc plates 211 and second arc plates 212, wherein the tops of the first arc plates 211 and the second arc plates 212 are symmetrically connected on both sides of the rotating base 1, and the bottoms of the first arc plates 211 and the second arc plates 212 are connected by a connecting block 4. The first arc plates 211 and the second arc plates 212 of this embodiment are both semicircular, so that the first arc plates 211 and the second arc plates 212 can form a circular FPC board 21 after splicing, and can form a sphere after rotation to achieve 360-degree holographic display, which not only reduces the production cost and difficulty, but also improves and reduces the deformation of the circular FPC board 21 during the rotation process, thereby making the overall strength of the circular FPC board 21 higher, which is convenient for improving better holographic display effects.

[0034] like Figure 4As shown, the two ends of the connection block 4 of this embodiment are respectively provided with plug-in ports 41, and the bottom of the first arc plate 211 and the bottom of the second arc plate 212 can be respectively plugged into the two plug-in ports 41 to achieve connection. The connection method is convenient and can effectively improve the stability and durability of the entire display component 2.

[0035] Since the 360-degree 3D holographic display of this embodiment is achieved by rotating the circular FPC board 21 to form a sphere so that the LED lamp beads 22 are displayed on the surface of the sphere, however, the circular FPC board 21 is easily deformed under the centrifugal action during high-speed rotation, which affects the effect of the 3D holographic display. Therefore, this embodiment provides a support frame 3 at the bottom of the rotating base 1. The support frame 3 can abut against the inner side of the circular FPC board 21 to support the circular FPC board 21, thereby reducing the deformation of the circular FPC board 21 during high-speed rotation, thereby achieving a good holographic display effect.

[0036] Specifically, Figure 1 and Figure 3 As shown, the support frame 3 of this embodiment includes at least four support parts 31 symmetrically arranged in pairs, wherein support sockets are provided on the end faces corresponding to each other of the rotating base 1 and the connecting block 4, and the symmetrical support parts 31 located at the top and bottom of the support frame 3 are respectively inserted into the two support sockets to fix the support frame 3, and the symmetrical support parts 31 located on the sides of the support frame 3 are respectively abutted against the inner sides of the first arc plate 211 and the second arc plate 212, thereby supporting the circular FPC board 21, which can effectively reduce the deformation caused by the rotation of the circular light board and improve the 360-degree 3D holographic display effect of this embodiment.

[0037] like Figure 3 As shown, in other embodiments, when there are two circular FPC boards 21, two symmetrical support parts 31 can be additionally provided on the side of the support frame 3 to support the circular FPC board 21 on the inner side thereof, and for each additional circular FPC board 21, two support parts 31 are additionally provided on the side of the support frame 3 for support, thereby achieving a good display effect of the display component 2 of this embodiment.

[0038] The holographic display device of this embodiment can also be used outdoors or in other special scenarios to prevent insects, dust or debris in the environment from affecting the display component 2. Figure 2 and Figure 5 As shown, the holographic display device of this embodiment can be further equipped with an outer cover 5, wherein the outer cover of this embodiment is a transparent or translucent shell, and its material includes but is not limited to glass, acrylic, PC board, etc., so that after the outer cover is installed, the 3D holographic effect displayed by the display component 2 can be displayed normally, and insects, dust or debris can be isolated to avoid affecting the normal display operation of the display component 2 in special places such as outdoors.

[0039] Specifically, the outer cover 5 of this embodiment includes a connection portion 51 mounted on the outside of the rotating base 1 and a display portion 52 mounted on the outside of the display assembly 2, which can well protect the display device, so that the display device of this embodiment can be set up for use in special scenes such as outdoors. An opening 511 is also provided on the connection portion 51 of this embodiment, so that the rotating base 1 can be connected to an external cable through the opening 511, thereby realizing power supply to the power supply assembly, the motor assembly, and the display assembly 2.

[0040] To summarize, in this embodiment, a circular FPC board 21 connected to the rotating base 1 is provided, and a plurality of LED lamp beads 22 are equidistantly provided on the surface of the circular FPC board 21, so that when the rotating base 1 rotates, the circular FPC board 21 can be driven to rotate to form a sphere, so that the LED lamp beads 22 mounted on the surface of the circular FPC board 21 can present a 3D holographic image effect from 360 degrees, thereby improving the user's viewing experience; at the same time, in this embodiment, a support frame 3 abutting against the inner side of the circular FPC board 21 is provided at the bottom of the rotating base 1, so that when the rotating base 1 drives the circular FPC board 21 to rotate 360 ​​degrees to form a 3D holographic image, the support frame 3 can support the circular FPC board 21, thereby preventing the circular FPC board 21 from deforming during high-speed rotation, thereby ensuring the display effect of the 3D holographic image.

[0041] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
