Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and specifically to a display device. Background Technology

[0002] With the rapid development of display technology, flexible LED displays, due to their lightweight, bendability, and adaptability to various surfaces, have been widely used in various fields such as vehicle window advertising, smart homes, and interior decoration. Flexible LED displays can not only display a rich variety of content, such as text, animation, and images, but also achieve remote control and personalized content display by combining with smart devices.

[0003] In existing technologies, flexible LED displays typically integrate the control device within the screen body, with both the control device and the screen body powered by an external power supply line. Existing flexible LED displays suffer from the following main problems in practical use: First, voice control functionality is limited; users cannot change the displayed content or adjust the screen's operating status via voice commands. Second, the shutdown of existing flexible LED displays usually relies on software control, achieving only a "soft shutdown." The physical power supply to the screen is not completely cut off, meaning the control device and screen body still consume power even when not in use, resulting in high power consumption, which is detrimental to long-term use and energy-saving requirements. Third, the content of existing flexible LED displays is stored in the control device's internal memory. When users need to change the displayed content, the limited built-in storage capacity and data transmission methods result in low material update efficiency and poor scalability, failing to meet the needs of dynamic content switching.

[0004] Therefore, the inability of existing flexible LED displays to achieve voice control, high power consumption when the screen is off, and low efficiency in updating displayed content are problems that urgently need to be solved. Utility Model Content

[0046] In this embodiment, the connecting line 3 is a two-wire structure, including a positive power supply terminal and a negative power supply terminal.

[0055] In one embodiment, an existing flexible LED display screen covers the main body with a protective film, which can be applied to various types of glass, such as car windows, allowing people outside to see the animations on the flexible LED display screen. The flexible LED display screen can display a wealth of content and can input various information such as text, animations, and images.

[0056] Existing similar products include flexible LED displays with built-in controllers, where the control device is integrated into the flexible LED display and the USB cable is used only for power supply.

[0057] The existing products have the following drawbacks: because the control components are on the screen, which is covered by a film, the microphone cannot be exposed, and voice control and hardware music rhythm functions cannot be realized; because the control device is on the screen, the screen can only be turned off softly, and the screen cannot be powered off unless the power is manually turned off physically, resulting in high power consumption.

[0058] This embodiment provides a voice-controlled flexible LED display screen. Previously, the controller was placed inside the screen and covered by a gel, preventing the microphone from capturing sound and thus hindering voice control. This new invention places the controller outside the screen. The controller has a microphone that captures voice signals, converts them into control commands, and sends them to the screen's control device via Bluetooth broadcast packets. The control device then parses the Bluetooth broadcast packets into control commands and displays the corresponding results. This solves the problem of flexible displays with built-in control devices being unable to use voice control.

[0059] This embodiment effectively solves the problems of limited voice acquisition, high power consumption, and low content switching efficiency caused by built-in controllers in traditional flexible LED displays by using an external controller design. Through the integrated voice control component in the external controller, voice signals can be efficiently acquired and processed, overcoming the limitation of microphone exposure caused by the screen's adhesive film, and enabling intelligent control of the screen display content via voice commands. Simultaneously, the physical control of the power supply status by the switching component completely cuts off the power when the screen is off, significantly reducing standby power consumption and meeting the energy-saving requirements for long-term use. Furthermore, the wireless communication design between the IoT transmitting and receiving components ensures fast and stable transmission of control signals, driving the screen to dynamically switch content, avoiding the low content switching efficiency caused by transmission limitations in traditional technologies. The overall device adopts a simplified two-wire power supply connection method, greatly reducing the complexity of wiring layout and improving the reliability and maintainability of the equipment. Through modular design, the controller is easier to repair and upgrade, thereby extending the equipment's lifespan and adaptability. In summary, this utility model significantly improves the functionality, energy efficiency, and application range of the display device.

[0060] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
