Description

Technical Field

[0001] The present application relates to the technical field of switching display content based on image materials, and in particular to a display content switching method based on cloud image material management. Background Art

[0002] With the rapid development of display device technology, LED flexible display screens are gradually being widely used in advertising display, car window decoration, and home smart devices due to their thinness, flexibility, and other characteristics. Modern users' functional requirements for display screens are not limited to the display of static content, but are more inclined to diversification, dynamicization, and convenience of operation. This requires that the display screen can quickly switch the display content and support remote interactive management. However, the existing technology for switching and managing display screen content has the following problems:

[0003] Inefficient display content storage and switching: Existing LED flexible displays usually store display content in the internal memory of the screen controller, and the storage capacity is limited. When users need to switch display content, they need to manually update the internal storage data through external devices (such as USB flash drives or computers), which is complicated and time-consuming. Especially in scenarios where content needs to be changed frequently (such as dynamic billboards), this method greatly reduces the efficiency of use and cannot meet users' needs for real-time and convenience.

[0004] Poor content scalability: Since the content storage of existing display screens relies on local storage, users cannot flexibly expand the storage capacity, and updating materials requires physical data transmission. For application scenarios that require a large amount of material rotation or rapid updates, such as car window advertising and dynamic decorative content, existing technologies are difficult to meet this demand.

[0005] Inconvenient display content management: In the existing technology, users cannot efficiently manage and switch display content through smart terminal devices (such as mobile phones or tablets). For example, users may need to filter, select and switch multiple materials in daily use, but the existing display screen lacks an intelligent content management mechanism, resulting in a poor user experience.

[0006] Insufficient hardware efficiency and user experience: In the existing technology, the display controller is usually unable to temporarily manage the loaded content. When switching materials, all material data needs to be retransmitted, which increases the delay of data transmission. At the same time, the utilization rate of storage resources is low, and hardware performance cannot be effectively optimized.

[0007] Therefore, how to design a display content switching method that can manage image materials based on the cloud, support fast switching, flexible storage and efficient management of display content, and optimize user experience and hardware efficiency has become a technical problem that needs to be solved urgently in this field.

[0072] In this embodiment, the number of the LED flexible display screens 4 is multiple;

Each of the LED flexible display screens 4 includes an independent second power supply component 11, an Internet of Things receiving component 12, a driving component 13 and a display component 14. The Internet of Things sending component 6 sends independent control signals to the Internet of Things receiving components 12 of the multiple LED flexible display screens 4 through wireless communication to control each of the LED flexible display screens 4 to display different content.

[0074] This embodiment provides a display content switching method based on cloud image material management, which is applied to a display system including an electronic device, an external controller, a connecting line, and an LED flexible display screen. Through this method, users can efficiently obtain image materials from a server and use an external controller to dynamically switch and manage display content to meet the usage requirements of different scenarios. The specific implementation steps are as follows:

[0075] In this embodiment, the first input is used to instruct the electronic device to obtain multiple image materials from the cloud library of the server. The electronic device can be a terminal device supporting wireless communication such as a smart phone or a tablet computer, and runs an application APP with an image management function.

[0076] After the user opens the APP, multiple image materials pre-stored in the server's cloud library will be loaded into the APP interface for the user to browse. In this step, the user issues a first input instruction by clicking the image loading button on the APP interface or performing other gesture operations such as sliding, confirming, etc., instructing the APP to communicate with the server and obtain the required image materials. The obtained materials will be directly displayed on the APP interface, for example, arranged in a grid, and the user can preview these materials.

[0077] The second input is used to instruct the user to select one or more second target image materials from the first target image material loaded by the first input, and send the selected second target image materials to the LED flexible display screen. The user completes the screening of the first target image material by clicking on the first target image material on the APP interface, such as checking or long pressing, and obtains the second target image material. Subsequently, the APP sends the second target image materials selected by these users to the LED flexible display screen through wireless communications such as Bluetooth or WiFi. After receiving the image material, the LED flexible display screen temporarily stores it in multiple image material temporary storage areas set in the LED flexible display screen. These image material temporary storage areas are volatile memories such as RAM, which can realize high-speed storage and reading operations, ensuring a quick response when the user needs to switch content.

[0078] The third input is used to instruct the user to switch display content and select a specific third target image material.

[0079] The user clicks the display or switch button in the APP interface to select the image material to be displayed on the LED flexible display, that is, the third target image material. After receiving the third input, the LED flexible display determines whether the selected third target image material already exists in the temporary storage area:

[0080] If the third target image material has been stored in the temporary storage area, it is directly loaded from the temporary storage area and displayed on the LED flexible display screen;

[0081] If the material does not exist in the temporary storage area, the third target image material is re-acquired from the server cloud library through the APP, stored in the temporary storage area, and then loaded onto the LED flexible display screen for display.

[0082] The external controller is connected to the LED flexible display screen through a connecting line, and sends corresponding control signals to drive the display component to display image content. Through such a design, the entire display system can quickly respond to user instructions and realize dynamic display content switching.

[0083] Through the above specific implementation, this embodiment can effectively solve the problems existing in the background technology, and the specific technical effects are as follows:

[0084] Solve the problem of low display content storage and switching efficiency: the display content storage of traditional display systems relies on local storage, and the storage data needs to be manually updated when switching materials, which is complicated and time-consuming. The present invention obtains image materials from the cloud server through the first input instruction, and combines the fast storage design of the temporary storage area to achieve high-speed loading and display when switching materials. The design of the temporary storage area avoids repeated transmission of the same material, greatly improving the efficiency of content switching.

[0085] Solve the problem of poor content scalability: In traditional technologies, the local storage capacity is limited and it is difficult to meet the dynamic needs of users for large quantities of image materials. The present invention stores the materials in the cloud library of the cloud server and dynamically obtains the cloud materials through the first input. The storage capacity of cloud materials is theoretically unlimited, and users can upload new materials to the server, which is much more scalable than traditional methods.

[0086] Solve the problem of inconvenient display content management: Traditional display systems require complex physical connections such as USB flash drives, SD cards or computers to update materials, which results in poor user experience. The present invention implements material screening and sending through a second input, and users can complete material screening, selection and transmission operations through the APP interface, greatly improving the convenience of display content management. In addition, the APP interface provides an intuitive material preview function, allowing users to quickly find target materials.

[0087] Improve hardware efficiency and user experience: Traditional display systems need to retransmit all materials when switching content, which increases data transmission delay and low storage resource utilization. The present invention uses the temporary storage area to preferentially load the stored target materials, reduce repeated transmission, and improve transmission efficiency and hardware resource utilization. At the same time, through the design of the local storage area, users can save materials that need to be displayed for a long time to non-volatile memory, ensuring that data is not lost after the device loses power, further improving the user experience.

[0088] Optimize the display content switching process: Users directly select the material to be displayed through the third input, and the system automatically determines whether the material needs to be retransmitted, and loads data from the temporary storage area or the cloud as needed. This design ensures that the display content switching process is smooth and efficient, without the need for users to repeat operations.

[0089] In this embodiment, the first input is used to instruct the electronic device to obtain a plurality of first target image materials from the server, representing the user's overall demand for the material list, such as a material loading operation.

[0090] The second input is used to further filter the second target materials from the multiple first target materials loaded by the first input, and send these second target materials to the LED flexible display screen, representing the user's filtering requirements for the first target materials, such as material uploading operations.

[0091] The third input is used to select the specific material that needs to be displayed on the LED flexible display screen, representing the user's final demand for the displayed content, such as content switching operations.

[0092] Through the division of labor among the first input, the second input, and the third input, this embodiment designs an efficient display content switching method based on cloud image material management, realizing the whole process from acquiring materials from the cloud to dynamically switching display content. The combination of the temporary storage area and the local storage area optimizes storage efficiency and hardware resource utilization, significantly improving the convenience and switching efficiency of display content management. This method successfully solves the problems of insufficient storage capacity, low switching efficiency, and inconvenient content management mentioned in the background technology, and has significant technical advantages and wide application value.

[0093] This embodiment effectively solves the problems of limited storage capacity, low switching efficiency and inconvenient display content management in the prior art through the design of cloud-based image material management. Through the first input, the user can dynamically obtain the first target image material from the cloud library of the server, realize the high scalability of material storage, and break through the limitation of local storage capacity in traditional technology; through the second input, the user can filter out the second target material from the first target image material loaded from the cloud and send it to the LED flexible display screen, which stores the second target material in the image material temporary storage area, supports fast loading, and avoids repeated transmission of the same material; through the third input, the user can choose to switch the display content, and the LED flexible display screen will load the display from the temporary storage area first according to whether the third target material has been stored in the temporary storage area, or complete the display switching after re-acquiring the third target material, which significantly improves the material switching efficiency. At the same time, the present invention relies on the APP interactive interface of the electronic device, allowing users to browse, filter and switch materials intuitively and efficiently, simplifying the operation process of display content management, and avoiding the cumbersome steps of traditional display systems that rely on physical transmission methods to update content. In summary, the present invention greatly improves the functionality and user experience of the display system through efficient material management, dynamic switching and intuitive interaction, and completely solves the related problems in the prior art.

[0094] In one embodiment, the prior art LED flexible display screen covers the main body with a protective film, which can be attached to various glasses and car windows, so that people outside can see the animation on the LED flexible display screen. The LED flexible display screen can display a lot of rich content, and can input various information such as text, animation, and pictures. Existing similar products: LED flexible display screen with built-in controller, the control device is built into the LED flexible display screen, and the USB cable is only used for power supply;

[0095] The shortcomings of existing products are as follows:

[0096] Since 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;

[0097] The control device is on the screen, and the screen can only be turned off softly. Unless the power is turned off manually and physically, there is no way to control the screen to be powered off, and the power consumption is high.

[0098] This embodiment provides a method for voice-controlled LED flexible display screen for voice-controlled LED flexible display screen. In the existing device, the controller is placed inside the screen body and covered with colloid, so the microphone cannot collect sound inside the screen body and the voice control function cannot be realized. This embodiment puts the controller outside the screen body, and the controller is equipped with a microphone. The voice collects the voice signal, and then converts it into a control command, which is sent to the control device of the screen body in the form of a Bluetooth broadcast packet. The control device parses the Bluetooth broadcast packet into a control command and presents the corresponding result. This solves the problem that the flexible display screen with a built-in control device cannot use voice control.

The smart phone is connected to the server. When the APP is opened, the APP obtains the image material on the server and displays it on the interface. The user clicks on the corresponding image, and the APP sends the corresponding material to the controller. The controller has multiple temporary storage areas for image materials. The controller stores the image material in the temporary storage area. When the user switches the content, if the material is already in the temporary storage area, it is directly displayed without resending the image material, saving switching time. If it is new content, the image material is resent and stored in the temporary storage area. The temporary storage area is a memory area, which is not saved when the power is off. The storage speed is fast, and the image data can be quickly stored, shortening the user's waiting time. In addition, there is an "Apply" button on the APP interface. When the customer determines that the image material should be displayed all the time, the "Apply" button is used to store the image material in the temporary storage area to the local storage area. The local storage area is a medium such as FLASH, and the data is not lost when the power is off. Through this method, the purpose of convenient replacement of image data is achieved, and the user does not need to wait too long during the image switching process, which optimizes the user experience.

[0120] In this embodiment, control instructions can be sent to the LED flexible display screen through a wireless remote control, a smart device, or offline voice to drive the display of related animation effects; by separating the controller from the LED flexible display screen, offline voice control can be achieved, and the controller sends a Bluetooth broadcast packet to the LED flexible display screen, thereby achieving the purpose of offline voice control.

[0121] This embodiment is composed of an input line, a controller, and an LED flexible display screen; the controller and the LED flexible display screen are connected by two wires, the positive and negative poles, and there is no signal line connected between them; the controller controls the LED flexible display screen wirelessly by sending Bluetooth broadcast packets; the LED flexible display screen uses ordinary RGB lamp beads, the screen body contains a control circuit, and uses a scanning method to drive the LED to display content;
