Technical Field
[0001] This utility model relates to the field of naked-eye 3D display screen technology, specifically a naked-eye 3D display screen structure. Background Technology
[0002] With the development of glasses-free 3D display technology, 3D display devices are gradually becoming more widely used in advertising, education, medical care, entertainment and other fields. Glasses-free 3D display devices add a specific grating layer or columnar lens in front of the display screen, allowing viewers to obtain stereoscopic visual effects without wearing 3D glasses. Compared with traditional 3D display devices, glasses-free 3D display devices have the advantages of user-friendly experience and wide applicability, and therefore have gradually become the research focus of the display technology field.
[0003] However, existing glasses-free 3D display devices face some challenges in practical use. First, glasses-free 3D devices usually require high-brightness and high-resolution LED displays to achieve realistic stereoscopic effects. However, LED displays generate a lot of heat when working for a long time. If the heat dissipation is not good, it will not only affect the display effect, but may also cause equipment failure or damage and shorten its service life. Therefore, how to effectively design a heat dissipation structure and reduce the operating temperature of LED displays is an urgent problem to be solved for glasses-free 3D display devices.
[0004] While existing technologies can improve heat dissipation by adding cooling fans, a large amount of dust in the air can enter the display screen during heat dissipation, causing display screen malfunctions. Although this can also be solved by adding dust filters, dust will adhere to the surface of the filter over time, reducing ventilation and affecting heat dissipation. Utility Model Content
[0005] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a naked-eye 3D display screen that effectively reduces failures caused by overheating, dust and other reasons, improves stability and durability, and extends service life.
[0006] The technical solution adopted by this utility model to achieve the above objectives is: a naked-eye 3D display screen structure, including a screen shell, an LED display screen, a columnar grating layer, and a glass layer. The LED display screen, the columnar grating layer, and the glass layer are fixedly connected sequentially from the inside to the outside of the screen shell. A heat dissipation area is provided between the LED display screen and the screen shell. A display screen control circuit integrated board is fixedly connected to the back of the screen shell. A protective cover is fixedly connected to the display screen control circuit integrated board on the back of the screen shell. An air outlet is provided at one end of the protective cover. A fan assembly is fixedly connected to the air outlet inside the protective cover. An air inlet is provided on the side of the protective cover away from the air outlet. A dust filter mechanism is provided at the air inlet.
[0007] In the above technical solution, the dust filtration mechanism includes a filter housing, a dust filter screen, and a linear motion module. The filter housing is fixedly connected to the protective cover corresponding to the air inlet. The linear motion module is provided inside the filter housing. The linear motion module includes a motion platform capable of linear motion. The dust filter screen is fixedly connected to the filter housing. A cleaning brush is fixedly connected to the motion platform, and the cleaning brush abuts against the dust filter screen.
[0008] In the above technical solution, the linear motion module further includes a sliding column, a lead screw, and a motor. The sliding column is fixedly connected inside the filter housing, the motion table is slidably connected to the sliding column, the lead screw is threadedly connected to the motion table, and the motor is fixedly connected to the filter housing. The motor is poweredly connected to the lead screw.
[0009] In the above technical solution, the columnar grating layer is in close contact with the LED display screen, and there is a gap between the columnar grating layer and the glass layer, and the gap is in a vacuum state.
[0010] In the above technical solution, the air outlet is located at the top of the protective cover, and the air inlet is located at the bottom of the protective cover.
[0011] The beneficial effects of this utility model are:
[0012] 1. By setting a heat dissipation area between the LED display screen and the screen housing, and integrating a fan group inside the protective cover, the display screen can effectively dissipate heat during long-term operation, prevent overheating problems, and extend the service life of the display screen;
[0013] 2. The air outlet is located on the top side of the protective cover, and the air inlet is located at the bottom away from the air outlet. This allows the fan assembly to carry a large amount of hot air from inside the protective cover to the outside, improving the heat dissipation effect.
[0014] 3. A dust filtration mechanism is designed, equipped with a linear motion module and an automatic cleaning brush, which can regularly clean the dust filter to prevent dust from entering the equipment, ensure the long-term stability of the equipment operation, and reduce maintenance needs;
[0015] 4. The bonding design between the LED display and the columnar grating layer ensures the clarity and visual depth of the 3D image. The vacuum gap between the columnar grating layer and the glass layer further reduces light interference, improves the overall visual effect, and enhances the naked-eye 3D experience.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 A naked-eye 3D display screen structure is disclosed. The screen structure includes a screen shell 100, an LED display screen 200, a columnar grating layer 300, and a glass layer 400. The LED display screen 200, the columnar grating layer 300, and the glass layer 400 are fixedly connected to the screen shell 100 from the inside to the outside. The columnar grating layer 300 is in close contact with the LED display screen 200, and a gap 101 is provided between the columnar grating layer 300 and the glass layer 400. The gap 101 is in a vacuum state. This close contact design between the LED display screen 200 and the columnar grating layer 300 improves the clarity of the 3D image, while the vacuum gap 101 between the columnar grating layer 300 and the glass layer 400 further reduces light interference, enhances the immersiveness of the naked-eye 3D display, and brings a better viewing experience.
[0024] In addition, a heat dissipation area 102 is provided between the LED display screen 200 and the screen housing 100 to dissipate the heat generated by the LED display screen 200 during long-term operation. The back of the screen housing 100 is fixedly connected to the display control circuit integrated board 500, which is mainly responsible for controlling the image output and display function of the LED display screen 200. In order to ensure the normal operation of the display control circuit integrated board 500, a protective cover 600 is fixedly connected to the back of the screen housing 100 covering the display control circuit integrated board 500. An air outlet 103 is provided at one end of the protective cover 600, and a fan assembly 104 is fixedly connected to the air outlet 103 inside the protective cover 600. An air inlet 105 is provided on the side of the protective cover 600 away from the air outlet 103. This layout allows the fan assembly 104 to carry a large amount of hot air inside the protective cover 600 to the outside, thereby improving the heat dissipation effect.
[0025] Furthermore, a dust filter mechanism 700 is also provided at the air inlet 105 to prevent dust from entering the interior and affecting the service life of the display screen. Specifically, the dust filter mechanism 700 includes a filter housing 701, a dust filter 702, and a linear motion module 703. The filter housing 701 is fixedly connected to the protective cover 600 corresponding to the air inlet 105. The linear motion module 703 is provided inside the filter housing 701. The linear motion module 703 includes a motion table 704, a sliding column 705, a lead screw 706, and a motor 707. That is, the sliding column 705 is fixedly connected inside the filter housing 701, and the motion table 704 is slidably connected to the sliding column 705. A lead screw 706 is threaded onto the filter housing 701, and a motor 707 is fixedly connected to it. The motor 707 is powered by the lead screw 706. When the motor 707 drives the lead screw 706 to rotate, the motion table 704 can slide linearly on the sliding column 705. A dust filter screen 702 is fixedly connected to the filter housing 701, and a cleaning brush 708 is fixedly connected to the motion table 704. The cleaning brush 708 abuts against the dust filter screen 702. In this way, the dust filter screen can filter the dust in the air. When it is necessary to clean the dust attached to the filter screen, the motor 707 works to make the cleaning brush 708 move linearly, thereby cleaning the dust off the dust filter screen 702.
[0026] Furthermore, the air outlet 103 is located at the top of the protective cover 600, and the air inlet 105 is located at the bottom of the protective cover 600. This allows the cleaned dust to fall directly due to gravity, while the hot air rises, allowing the air outlet 103 to quickly expel the heat.
