[0005] 3. Effective optical enhancement technologies, such as using films of different materials to improve display performance.

[0006] 4. Convenient moving and fixing technology to meet the location and stability requirements of equipment in different scenarios.

[0007] Currently, to improve the safety and display effect of naked-eye 3D splicing screens, most displays have a protective case around the screen. The protective case not only prevents external factors from causing physical damage to the screen, but also allows for the installation of films that further enhance the display effect.

[0008] However, existing protective cases have significant shortcomings in terms of installation. Specifically, they lack an effective and rapid positioning mechanism during installation. Installers often need to spend a lot of time aligning the protective case with the display screen and making repeated adjustments to ensure accurate installation. This not only increases the difficulty of installation but also consumes a lot of manpower and time, reducing work efficiency. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this utility model provides a 3D effect enhancement lens device for naked-eye 3D splicing screens. It solves the technical problem that during installation, the lack of an effective and rapid positioning mechanism often requires installers to spend a lot of time aligning the protective shell and the display screen, repeatedly adjusting to ensure accurate installation. This not only increases the difficulty of installation but also consumes a lot of manpower and time costs, reducing work efficiency.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A 3D effect enhancement lens device for a naked-eye 3D splicing screen includes a display device body and an mounting bracket. Both the display device body and the mounting bracket have a positioning mechanism for lens mounting at their upper ends. The positioning mechanism includes two semi-circular positioning seats, two interlocking blocks, and two push handles. The two semi-circular positioning seats are respectively fixedly connected to the upper ends of the display device body and the mounting bracket, and the two semi-circular positioning seats are in contact with each other. The two interlocking blocks are respectively rotatably connected inside the two semi-circular positioning seats. The two push handles are respectively fixedly connected to the outer surfaces of the two interlocking blocks. Each of the two semi-circular positioning seats has a set of Phillips head screws inside, and the two sets of Phillips head screws are respectively threaded into the display device body and the mounting bracket.

[0012] Preferably, both push handles have slots inside, and both semicircular positioning seats have ball-head inserts slidably connected inside.

[0013] Preferably, the two ball-head inserts are respectively inserted into the two slots, and the upper ends of the two ball-head inserts are fixedly connected with cross rods.

[0014] Preferably, each of the two semicircular positioning seats has a spring fixedly connected inside, and the two springs are respectively fixedly connected to the outer surface of the two ball-head inserts.

[0015] Preferably, the main body of the display device and the mounting bracket are provided with an assembly screw, and the outer surface of the assembly screw is threaded with a locking nut.

[0016] Preferably, the locking nut is in contact with the outer surface of the display device body, and a display enhancement film is fixedly connected to the outer surface of the mounting bracket.

[0017] Preferably, the display device body has a set of splicing screen bodies inside, and the display enhancement film is located on the outer surface of the set of splicing screen bodies.

[0018] Preferably, a movable base is fixedly connected to the lower end of the main body of the display device, and a set of universal wheels is fixedly connected to the lower end of the movable base.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. During assembly, attach the mounting bracket to the surface of the display device body. Then, hold the two push handles and rotate the interlocking blocks. The two interlocking blocks extend into the interior of another semi-circular positioning seat, forming an interlock, thus achieving a quick positioning effect. This provides a fast positioning method for subsequent assembly and fixing operations, thereby speeding up the assembly work efficiency, greatly simplifying the assembly operation process, and saving assembly time. This simplified operation can significantly improve work efficiency and shorten the equipment installation cycle.

[0021] 2. By installing brackets on the surface of the main display device, a set of splicing screen bodies are provided with shielding protection. The interior of the splicing screen body near the display enhancement film is a diffraction grating. The grating can diffract and split the light, so that the light of different colors is more accurately distributed in the direction of propagation, improving the purity and contrast of colors. The display enhancement film installed on the surface of the splicing screen body is a lenticular lens film. The display enhancement film divides the display pixels into sub-pixel groups corresponding to the left and right eyes. With the help of the lens refraction characteristics, the light of different sub-pixel groups is directed to the left and right eyes of the viewer respectively, simulating binocular parallax. At the same time, the lenticular lens film also increases the focal point and deepens the focal depth, so that the brightness is stable when the viewing angle changes, the sub-pixel transition is smooth, the moiré stripes are reduced, and the 3D display effect is enhanced in all aspects.

[0029] This application provides a 3D effect enhancement lens device for a naked-eye 3D splicing screen, effectively solving the problem of a lack of effective rapid positioning mechanism during installation. Installers often need to spend a lot of time aligning the protective shell and the display screen, repeatedly adjusting to ensure accurate installation. This not only increases installation difficulty but also consumes significant manpower and time, reducing work efficiency. During assembly, the mounting bracket is attached to the surface of the display device. Then, by holding and rotating the two push handles, the interlocking blocks on the surface are rotated. The two interlocking blocks extend into the interior of another semi-circular positioning seat, forming an interlock, thus achieving rapid positioning. This provides a quick positioning method for subsequent assembly and fixing operations, thereby accelerating device assembly efficiency, greatly simplifying the assembly process, and saving assembly time. This simplified operation significantly improves work efficiency and shortens the equipment installation cycle.

[0030] Example:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this application embodiment effectively solves the technical problem that during installation, the lack of an effective rapid positioning mechanism means that installers often need to spend a lot of time aligning the protective shell and the display screen, repeatedly adjusting to ensure accurate installation. This not only increases the difficulty of installation but also consumes a lot of manpower and time, reducing work efficiency. The overall idea is as follows: A 3D effect enhancement lens device for a naked-eye 3D splicing screen includes a display device body 11 and an mounting bracket 12. The upper ends of both the display device body 11 and the mounting bracket 12 are provided with a positioning mechanism for lens mounting. The positioning mechanism includes two semi-circular positioning seats 13, two interlocking blocks 14, and two push handles 15. The two semi-circular positioning seats 13 are respectively fixedly connected to the upper ends of the display device body 11 and the mounting bracket 12, and the two semi-circular positioning seats 13 are in contact with each other. The two interlocking blocks 14 are respectively rotatably connected inside the two semi-circular positioning seats 13, and the two push handles 15 are respectively fixedly connected to the outer surfaces of the two interlocking blocks 14. Each of the two semicircular positioning seats 13 has a set of cross screws 16 inside. The two sets of cross screws 16 are threaded into the display device body 11 and the mounting bracket 12, respectively. When assembling the display device body 11 and the mounting bracket 12, the two semicircular positioning seats 13 are installed at corresponding positions on the upper end of the display device body 11 and the mounting bracket 12 by screwing in the cross screws 16. Each of the two semicircular positioning seats 13 has a semicircular through groove inside. The two semicircular through grooves are connected to form a complete cylindrical through groove. The two interlocking blocks 14 and the two push handles 15 rotate in the cylindrical through groove. During the assembly operation, the mounting bracket 12 is attached to the surface of the display device body 11. At this time, the two push handles 15 are held and the interlocking blocks 14 are screwed in to rotate. The two interlocking blocks 14 extend into the other semicircular positioning seat 13, and the two interlocking blocks 14 form an interlock, thereby achieving a quick positioning effect and providing a quick positioning method for subsequent assembly and fixing operations, thereby speeding up the efficiency of device assembly.

[0032] Both push handles 15 have slots 17 inside, and both semi-circular positioning seats 13 have ball-end rods 18 slidably connected inside. The ball-end rods 18 are respectively inserted into the two slots 17. A cross-shaped pull rod 19 is fixedly connected to the upper end of each ball-end rod 18. Springs 21 are fixedly connected inside each semi-circular positioning seat 13, and the springs 21 are respectively fixedly connected to the outer surface of the two ball-end rods 18. Assembly screws 22 are provided inside the display device body 11 and the mounting bracket 12. Locking nuts 23 are threaded onto the outer surface of the assembly screws 22, and the locking nuts 23 are threaded onto the outer surface of the display device body 11. Before operating the interlocking block 14, the operator can hold the cross lever 19 and pull the ball head insertion rod 18 upwards to slide it. When the ball head insertion rod 18 slides, it will compress the spring 21. When the push handle 15 is turned and fits against the inner wall of the semi-circular positioning seat 13, this is the maximum stroke. Release the pull of the cross lever 19, and under the elastic force of the spring 21, push the ball head insertion rod 18 to slide into the slot 17, thereby ensuring the stability of the positioning operation. After the initial positioning is completed, the assembly screw 22 can be aligned and inserted into the display device body 11 and the mounting bracket 12, and then the locking nut 23 can be turned to fix the installation.

[0033] A display enhancement film 24 is fixedly connected to the outer surface of the bracket 12. A set of splicing screen bodies 25 is installed inside the main body 11 of the display device. The display enhancement film 24 is located on the outer surface of the splicing screen bodies 25. A movable base 26 is fixedly connected to the lower end of the main body 11, and a set of casters 27 is fixedly connected to the lower end of the movable base 26. The splicing screen bodies 25 are installed inside the main body 11 through splicing assembly. The main body 11 and the splicing screen bodies 25 together constitute a naked-eye 3D splicing display screen. The display screen utilizes parallax... 3D effects are achieved using technologies such as barrier or lenticular lenses. The screen is composed of multiple display units spliced ​​together, with a lenticular lens array in front of each unit. The pixels of the display units are specially arranged into pixel groups corresponding to the left and right eyes. The lenticular lenses refract light, so that the light from the left and right eye pixel groups is precisely projected into the left and right eyes of the viewer. Utilizing the binocular parallax of the human eye, the brain combines the different images received by the left and right eyes into a 3D scene with a sense of depth, allowing viewers to see a naked-eye 3D effect without the need for auxiliary equipment. This 3D viewing effect is used for display, advertising, and exhibitions. For tasks such as viewing, the main body 11 of the display device provides mobility through a movable base 26 installed at the bottom. The movable base 26 provides mobility through casters 27 installed at the bottom, and the casters 27 have a locking function to ensure the overall stability of the device during display, promotion, and exhibition. A bracket 12 is installed on the surface of the main body 11 to provide shielding protection for a set of splicing screen bodies 25. The interior of the splicing screen body 25 near the display enhancement film 24 is a diffraction grating, which can diffract and split light. This allows for more precise distribution of light of different colors in the direction of propagation, improving color purity and contrast. Furthermore, the display enhancement film 24 installed on the surface of the splicing screen body 25 is a lenticular lens film. The display enhancement film 24 divides the display pixels into sub-pixel groups corresponding to the left and right eyes. By utilizing the refractive properties of the lens, the light from different sub-pixel groups is directed to the left and right eyes of the viewer, simulating binocular parallax. At the same time, the lenticular lens film also increases the focal point and deepens the focal depth, making the brightness stable when the viewing angle changes, the sub-pixel transition smooth, reducing moiré patterns, and comprehensively enhancing the 3D display effect.

[0034] To address the problems existing in the prior art, this utility model provides a 3D effect enhancement lens device for a naked-eye 3D splicing screen. During assembly, the mounting bracket 12 is attached to the surface of the display device body 11. At this time, the two push handles 15 are held and the interlocking blocks 14 are rotated. The two interlocking blocks 14 extend into the interior of another semi-circular positioning seat 13, forming an interlock, thereby achieving a rapid positioning effect. This provides a quick positioning method for subsequent assembly and fixing operations, thereby speeding up the device assembly work efficiency, greatly simplifying the assembly operation process, and saving assembly time. This simplified operation can significantly improve work efficiency and shorten the equipment installation cycle.

[0035] Working principle:

[0036] The first step involves assembling a set of splicing screen bodies 25 within the main display device 11. The main display device 11 and the splicing screen bodies 25 together form a complete naked-eye 3D splicing display screen. The screen utilizes parallax barriers or lenticular lenses to achieve a 3D effect. The screen is composed of multiple display units, each with a lenticular lens array in front. The pixels of the display units are specially arranged, divided into pixel groups corresponding to the left and right eyes. The lenticular lenses refract light, allowing the light from the left and right eye pixel groups to be precisely projected into the viewer's left and right eyes respectively. Utilizing the binocular parallax of the human eye, the brain synthesizes the different images received by the left and right eyes into a 3D scene with depth, allowing viewers to see a naked-eye 3D effect without auxiliary equipment. This 3D viewing effect is used for display, advertising, and exhibitions. The main display device 11 is movable via a lower movable base 26, which is equipped with casters at its lower end. 27 provides mobility, and the casters 27 have a locking function, which can ensure the overall stability of the device during display, promotion, and exhibition. The main body 11 of the display device is protected by a bracket 12. The interior of the splicing screen body 25 near the display enhancement film 24 is a diffraction grating. The grating can diffract and split the light, so that the light of different colors is more accurately distributed in the direction of propagation, improving the purity and contrast of the colors. The display enhancement film 24 installed on the surface of the splicing screen body 25 is a lenticular lens film. The display enhancement film 24 divides the display pixels into sub-pixel groups corresponding to the left and right eyes. With the help of the lens refraction characteristics, the light of different sub-pixel groups is directed to the left and right eyes of the viewer respectively, simulating binocular parallax. At the same time, the lenticular lens film also increases the focal point and deepens the focal depth, making the brightness stable when the viewing angle changes, the sub-pixel transition is smooth, and the moiré stripes are reduced, thus enhancing the 3D display effect in all aspects.

[0037] In the second step, during the assembly of the display device body 11 and the mounting bracket 12, two semi-circular positioning seats 13 are installed at corresponding positions on the upper ends of the display device body 11 and the mounting bracket 12 by tightening the Phillips head screws 16. Each of the two semi-circular positioning seats 13 has a semi-circular through groove inside, which connect to form a complete cylindrical through groove. Two interlocking blocks 14 and two push handles 15 rotate within the cylindrical through groove. During assembly, the mounting bracket 12 is placed against the surface of the display device body 11. At this time, the interlocking blocks 14 are rotated by holding the surfaces of the two push handles 15. The two interlocking blocks 14 extend into the other semi-circular positioning seat 13 (i.e., the interlocking blocks 14 in the upper semi-circular positioning seat 13 of the display device body 11 rotate to the upper end of the mounting bracket 12, and vice versa). 14 will rotate into the display device body 11), and the two interlocking blocks 14 form an interlock, thereby achieving a quick positioning effect and providing a quick positioning method for subsequent assembly and fixing operations, thus speeding up the device assembly work efficiency. Before operating the interlocking blocks 14, the operator can hold the cross lever 19 and pull the ball head insertion rod 18 upward to slide it. When the ball head insertion rod 18 slides, it will compress the spring 21. When the push handle 15 is turned and fits against the inner wall of the semi-circular positioning seat 13, this is the maximum stroke. Release the pull of the cross lever 19, and under the elastic force of the spring 21, push the ball head insertion rod 18 to slide into the slot 17, thereby ensuring the stability of the positioning operation. After the initial positioning is completed, the assembly screw 22 can be aligned and inserted into the display device body 11 and the mounting bracket 12, and then the locking nut 23 can be turned to fix the installation.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
