[0045] Refer to Figure 5 , Figure 5 is a structural diagram of the flexible screen 110 of the aerial flexible screen according to an embodiment of the present invention;

[0046] In one embodiment, the aerial flexible screen includes: a first rod body 101, with hanging rings 102 for installing the rope positions respectively provided at both ends; a flexible screen 110, with one end fixedly connected to the first rod body 101, and a plurality of display units 111 arranged in an array on one side of the flexible screen 110, and the flexible screen 110 displays images through the display units 111; a second rod body 120, fixedly connected to the other end of the first rod body 101; a suspension rope 130, with both ends respectively fixedly connected to the hanging rings 102, and the suspension rope 130 being used to connect to a flying device to suspend the flexible screen 110 in the air; a storage bag 140, connected to the first rod body 101, and the storage bag 140 being used to place the power supply 142 and the signal receiving device 141; the signal receiving device 141, placed in the storage bag 140, and the signal receiving device 141 being used to receive external video signals; the power supply 142, placed in the storage bag 140, with the power supply 142 electrically connected to the signal receiving device 141 and the display unit 111, and the power supply 142 being used to supply power to the signal receiving device 141 and the display unit 111. The flexible screen 110 is a transparent screen. The flexible screen 110 includes, sequentially laminated: a transparent bottom layer 151, a display layer 152, and a PET film layer 153, and the display units 111 constitute the display layer 152.

[0047] I. Transparent bottom layer 151

[0048] Provide good support and stability: The transparent bottom layer 151, as the bottom structure of the flexible screen 110, provides a solid foundation for the entire screen. It can withstand a certain amount of pressure and tension, ensuring that the screen remains flat and stable in various usage environments, and is not easily deformed or damaged.

[0049] For the flexible screen 110, its bendable and foldable characteristics require the bottom structure to have sufficient strength and rigidity to prevent cracking or damage during the bending or folding process. The transparent bottom layer 151 can meet this requirement and provide reliable support for the display layer 152 and other layers.

[0050] High transparency ensures the display effect:

[0051] The transparent bottom plate layer 151 has high transparency, allowing light to pass through fully without affecting the image display effect of the display layer 152. This enables the flexible screen 110 to maintain clear, vivid colors and high contrast when displaying images, providing users with a high-quality visual experience.

[0052] The bottom plate layer with high transparency can also reduce the reflection and scattering of light, improving the readability and viewing angle of the screen. Whether in indoor or outdoor environments, users can easily see the content on the screen.

[0053] II. Display layer 152

[0054] Achieving high-quality image display: The display layer 152 is the core part of the flexible screen 110, responsible for presenting images and information. It is usually composed of organic light-emitting diodes (OLEDs), liquid crystal displays (LCDs), or other display technologies. These display technologies can provide high resolution, high color saturation, and fast response time, bringing excellent visual effects to users.

[0055] The display layer 152 of the flexible screen 110 can be bent and folded as needed without affecting the image quality. This gives the flexible screen 110 greater flexibility and adaptability in various application scenarios, such as wearable devices, foldable mobile phones, etc.

[0056] Thin and light design to adapt to flexible requirements: To achieve the bendable and foldable characteristics of the flexible screen 110, the display layer 152 usually adopts a thin and light design. This not only helps reduce the weight and thickness of the entire screen but also improves the flexibility and durability of the screen.

[0057] The thin and light display layer 152 can also reduce energy consumption and improve the battery life of the device. At the same time, it also provides more possibilities for the design of the device, making the device thinner, lighter, and more portable.

[0058] III. PET film layer

[0059] Protect the display layer 152 from external damage: As the outermost layer of the flexible screen 110, the PET film layer can effectively protect the display layer 152 from external scratches, abrasions, and impacts. The PET film has high hardness and wear resistance, capable of resisting various damages in daily use and extending the service life of the screen.

[0060] In addition, the PET film also has a certain impact resistance, which can play a buffering role when the screen is accidentally impacted, reducing the risk of damage to the display layer 152.

[0061] Provide good flexibility and foldability: The PET film itself has good flexibility and foldability. When combined with other layers of the flexible screen 110, it can achieve the bendable and foldable characteristics of the entire screen. This enables the flexible screen 110 to adapt to different shape and size requirements, bringing more usage methods and experiences to users. The flexibility of the PET film also ensures that the screen will not produce obvious creases during the bending or folding process, maintaining a good appearance and display effect.

[0062] In summary, the flexible screen 110 successively laminated with the transparent bottom plate layer 151, the display layer 152, and the PET film layer has the advantages of stable support, good display effect, protection of the display layer 152, and strong flexibility. This structural design makes the flexible screen 110 have broad development prospects in various application scenarios.

[0063] Refer to Figure 6 , Figure 6 which is the structural diagram of the aerial demonstration device in the embodiment of the present utility model.

[0064] In one embodiment, the aerial demonstration device includes the above-mentioned aerial flexible screen and an industrial unmanned aerial vehicle 210. A hook 211 is provided at the bottom of the industrial unmanned aerial vehicle 210, and the suspension rope 130 is hung on the hook 211. The unmanned aerial vehicle hovers in the air, and the installation of the aerial flexible screen is not restricted to a certain fixed position and height. It can display the required pictures and information at high altitude, having great freedom in terms of spatial position, viewing angle, etc., and being able to meet various video viewing needs.

[0065] The beneficial effects are as follows:

[0066] I. High flexibility

[0067] Free choice of position: Since the installation of the aerial flexible screen is not restricted to a certain fixed position and height, the industrial unmanned aerial vehicle 210 can take it to various different aerial positions. This allows the display to be flexibly adjusted according to specific requirements and scenarios. Whether it is in the center of a square, above a building, or a specific event area, the best display position can be found to attract more attention.

[0068] For example, in large-scale outdoor activities, the aerial flexible screen can be hovered at a prominent position above the crowd to ensure that viewers from all angles can clearly see the display content, without being restricted by ground obstacles or the position of fixed display facilities.

[0069] Highly adjustable at will: The drone can easily adjust the height of the aerial soft screen. In different environments, the appropriate height can be selected according to the viewing angle, the height of surrounding buildings, and the scale of the event. For example, when displaying in a low indoor venue, the soft screen can be adjusted to a lower height for the audience to view closely; while in a vast outdoor venue, the soft screen can be raised so that it can be clearly seen from a farther distance.

[0070] This adjustability of height can also cope with different weather conditions. In windy weather, the height of the soft screen can be appropriately reduced to reduce shaking; while in strong sunlight, the soft screen can be raised to avoid reflection affecting the viewing effect.

[0071] II. Outstanding display effect

[0072] High-altitude display attracts attention: The aerial soft screen has a unique visual impact when displayed at high altitude, and can quickly attract people's attention. Looking up from the ground, the display image in the air often becomes the focus. Whether it is for advertising, information dissemination or artistic performances, it can leave a deep impression on the audience.

[0073] Compared with traditional ground display methods, high-altitude display is more innovative and fresh. It breaks through the limitations of flat display, brings a brand-new visual experience to the audience, and increases the attractiveness and memory points of the display content.

[0074] Unobstructed broad vision: Since the aerial soft screen does not depend on a fixed ground position, it can avoid obstacles such as buildings and trees on the ground and achieve unobstructed display. This enables the display content to be seen within a wider range, improving the dissemination effect of information.

[0075] Whether in the city center or remote areas, the aerial soft screen can find a suitable display position to ensure that the display content can be conveyed to as many audiences as possible. At the same time, unobstructed display is also conducive to improving the clarity and color saturation of the image, enabling the audience to better appreciate the display content.

[0076] III. Strong adaptability

[0077] Meet different venue requirements: This setting can adapt to various different venue conditions. Whether it is a flat square, a rugged mountain or a narrow street, the industrial drone 210 can carry the aerial soft screen to a suitable position for display. For some venues where it is difficult to install fixed display equipment, such as temporary event venues, outdoor venues, etc., this method is particularly applicable.

[0078] For example, in an outdoor music festival held in the mountainous area, the ground venue may be uneven and lack fixed display facilities. However, through the combination of the industrial drone 210 and the aerial soft screen, performance information and sponsor advertisements can be displayed above the valley or between the mountain peaks, adding highlights to the event.

[0079] Quick deployment and evacuation: The setting of the industrial drone 210 carrying the aerial soft screen has the advantages of quick deployment and evacuation. In emergency situations, such as disaster relief and the release of information on emergencies, the aerial soft screen can be quickly deployed to the designated location to convey important information to the public in a timely manner. After the event, it can also be quickly evacuated without occupying the ground space and reducing the impact on the venue.

[0080] This quick response ability makes the aerial soft screen an efficient information dissemination tool that can play the greatest role in the shortest time. At the same time, quick deployment and evacuation also reduce the maintenance cost and risk of the equipment and improve the usage efficiency of the equipment.

[0081] In one embodiment, the aerial demonstration system includes the aerial demonstration device and the signal sending device as described above. The signal sending device is wirelessly communicatively connected to the signal receiving device 141, and the signal sending device is used to send video signals.

[0082] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
