[0049] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0050] To address the aforementioned technical problems, as a first aspect of the present invention, a driving method for a target display device is provided, such as... Figure 1 As shown, the driving method includes:

[0051] S1. Obtain the identity identifier of the display device to be replaced in the splicing screen, wherein the splicing screen includes multiple display devices, and each display device has a unique identity identifier;

[0052] S2. Obtain the display file corresponding to the display device to be replaced based on the obtained identity identifier.

[0053] It should be noted that the driving method provided in this embodiment of the invention is implemented through the target display device, which is a backup display device in the splicing screen system. When a display device in the splicing screen (i.e., the aforementioned display device to be replaced) malfunctions, the target display device (i.e., the backup display device) obtains its identity identifier and retrieves the corresponding display file based on that identifier. In this embodiment of the invention, the target display device can actively retrieve the display file corresponding to any display device. When a display device to be replaced (i.e., a faulty display device) appears in the splicing screen, the target display device (i.e., the backup display device) can directly retrieve the corresponding display file based on the identity identifier of the display device to be replaced, thereby improving the efficiency of loading display files onto the backup display device when replacing a display device.

[0054] The present invention does not specifically limit how the target display device obtains the display file corresponding to the display device to be replaced in step S2. For example, the target display device can download the corresponding display file from the file management platform through a wireless network, or it can connect to the display device to be replaced and share its display file with the display device to be replaced.

[0055] To improve the stability of display device replacement and ensure operational efficiency, preferably, as follows: Figure 2 As shown, step S2 includes:

[0056] Based on the obtained identity identifier, retrieve the display file corresponding to the display device to be replaced from the storage device.

[0057] In the embodiments provided by this invention, the backup display device can be directly connected to a storage device that stores display files corresponding to multiple display devices in the spliced ​​screen. The backup display device directly obtains the display file corresponding to the display device to be replaced from the storage device. Compared with the scheme where the display device obtains display files through a wireless network, this improves the security of the display file information, and the transmission speed of the display files is not affected by the network signal quality, thereby improving the success rate and operational efficiency of obtaining display files.

[0058] The present invention does not specifically limit the type of hardware of the storage device. For example, the storage device may be a USB flash drive, a portable hard drive, a Secure Digital Card (SD card), etc.

[0059] The present invention does not specifically limit how the backup display device obtains the identification. For example, maintenance personnel can connect to the target display device (i.e. the backup display device) through a handheld editing device and input the corresponding identification into the target display device through the handheld editing device.

[0060] To improve the operational efficiency of replacing display devices, preferably, such as Figure 3 As shown, the method further includes:

[0061] S11. In response to the obtained identity identifier, display the identity identifier.

[0062] In this embodiment of the invention, when the backup display device acquires the identity identifier, it can display the identity identifier on the display screen to prompt the staff whether the identity identifier has been entered correctly, thereby avoiding errors in identity identifier input and improving the operational efficiency of replacing the display device.

[0063] To further improve the operational efficiency of replacing the display device, preferably, such as Figure 4 As shown, the method further includes:

[0064] S21. In response to the obtained display file, generate and display a success signal.

[0065] In this embodiment of the invention, when the backup display device acquires the display file, it can generate a successful acquisition signal and display the successful acquisition signal on the display screen to prompt the staff whether the display device has successfully acquired the display file, thereby improving the operational efficiency of replacing the display device.

[0066] To further improve the operational efficiency of replacing the display device, preferably, such as Figure 5 As shown, the method further includes:

[0067] S22. In response to the obtained display file, generate and display the quantity information of the display file.

[0068] Video wall displays are typically used for more than just displaying the same image or video. For example, billboards often switch between displaying advertisements from different brands over time, and video wall performances usually include multiple different programs. Each display device within the video wall may also play multiple different display files within different brand advertisements or different programs. In this embodiment of the invention, when a backup display device acquires a display file, it can generate quantity information of the display files and display this quantity information on the screen to indicate to staff whether the display device has acquired all display files, thereby improving the operational efficiency of replacing the display device.

[0069] To achieve synchronization between the target display device and other normal display devices, preferably, such as Figure 6 As shown, the method further includes the following steps after step S2:

[0070] S3. In response to the received excitation signal, drive the display screen to display using the acquired display file.

[0071] In this embodiment of the invention, after the target display device obtains the display file, it does not play the display file immediately. When the target display device is in place at the position of the original faulty display device in the splicing screen, and the display progress of other normal display devices reaches the point where the display file needs to be played, the target display device will receive an excitation signal. At this time, the target display device responds to the received excitation signal to drive the display screen to display the display file, thereby achieving synchronization with other display devices and forming a complete picture together.

[0072] As a second aspect of the present invention, a display device is provided, such as... Figure 7 As shown, the display device includes an identity acquisition module 10 and a display file acquisition module 20, wherein:

[0073] The identity acquisition module 10 is used to perform step S1, that is, the identity acquisition module 10 is used to acquire the identity of the display device to be replaced in the splicing screen. The splicing screen includes multiple display devices, and each display device has a unique identity.

[0074] The display file acquisition module 20 is used to execute step S2, that is, the display file acquisition module 20 is used to acquire the display file corresponding to the display device to be replaced according to the acquired identity identifier.

[0075] The beneficial effects of the driving method used by the display device to perform the above-described invention have been described in detail in this invention, and will not be repeated here.

[0076] To improve the stability of display device replacement and ensure operational efficiency, preferably, as follows: Figure 8 As shown, the display file acquisition module 20 includes a storage device reading unit 01, which is used to acquire the display file corresponding to the display device to be replaced from the storage device according to the acquired identity identifier.

[0077] When the storage device is a USB flash drive or a portable hard drive, the file acquisition module 20 may include a USB interface for inserting the USB flash drive or portable hard drive; when the storage device is a security digital card, the file acquisition module 20 may include a security digital card slot for inserting the security digital card.

[0078] To improve the operational efficiency of replacing display devices, preferably, such as Figure 9 As shown, the display device further includes an identification information generation module 11, which is used to perform step S11, that is, when the identification identification acquisition module obtains the identification, the identification information generation module 11 drives the display screen to display the identification.

[0079] To further improve the operational efficiency of replacing the display device, preferably, such as Figure 10 As shown, the display device further includes a success signal generation module 21, which is used to execute step S21, that is, when the display file acquisition module acquires the display file, the success signal generation module 21 generates an acquisition success signal and drives the display screen to display the acquisition success signal.

[0080] To further improve the operational efficiency of replacing the display device, preferably, such as Figure 11 As shown, the display device further includes a quantity information generation module 22, which is used to perform step S22, that is, when the display file acquisition module acquires the display file, the quantity information generation module 22 generates the quantity information of the display file and drives the display screen to display the quantity information.

[0081] To ensure that the backup display device is synchronized with other normal display devices, preferably, such as Figure 12 As shown, the display device further includes an excitation signal receiving module 31 and a display control module 32, wherein:

[0082] The excitation signal receiving module 31 and the display control module 32 are used to execute step S3, that is, the excitation signal receiving module 31 is used to receive the excitation signal; the display control module 32 is used to drive the display screen to display using the acquired display file when the excitation signal receiving module 31 receives the excitation signal.

[0083] As a third aspect of the present invention, a splicing screen system is provided, the splicing screen system including a plurality of display devices, wherein at least one of the plurality of display devices of the splicing screen system is the display device described above.

[0084] In this embodiment of the invention, the backup display device can actively obtain the display file corresponding to any display device. When a display device to be replaced (i.e. a faulty display device) appears in the splicing screen, the backup display device can directly obtain the corresponding display file through the identification of the display device to be replaced, thereby improving the efficiency of loading display files to the backup display device when replacing the display device.

[0085] To achieve synchronization between the backup display device and other normal display devices, preferably, the display device is the aforementioned display device including an excitation signal receiving module. The splicing screen system also includes a signal transmitting device, which can send an excitation signal to the display device so that the backup display device can display the image synchronously with other display devices.

[0086] To facilitate understanding by those skilled in the art, the present invention also provides a specific embodiment for applying the above-described driving method, display device, and splicing screen system to splicing screen performances:

[0087] In group splicing screen performances, each official performer carries a display device with a unique identifier and enters each performance area, taking their place in their respective performance position. As the official performers operate the device and the display device shows the image, the entire splicing display device moves into various graphics.

[0088] The splicing display device is divided into multiple performance blocks, each of which includes multiple display devices. At least one reserve team member is mixed into each performance block. When a reserve team member finds that an individual display device in the block under their responsibility is displaying abnormally (black screen, distorted screen, faulty light board, or out of control), the reserve team member moves to the problematic display device, notes and reports the identification of the faulty display device, shuts down the faulty display device, and takes the faulty display device to the nearest repair point.

[0089] Upon receiving a faulty display device, maintenance personnel first confirm whether it needs to be replaced. If replacement is required, the personnel retrieve a working spare display device and connect its USB interface and motherboard RS232 serial port to a handheld editing device. This connects the handheld editing device to the control system of the spare display device. The personnel then input the identification identifier of the faulty display device reported by a reserve team member into the handheld editing device. The spare display device displays the input identifier on its screen, such as... Figure 13 As shown, the display screen shows the identification number "3712" entered by the staff.

[0090] After confirming that the identification number "3712" was entered correctly, the staff inserted the USB flash drive into the USB port on the backup display device. Figure 14 As shown, the backup display device copies the display file corresponding to the faulty display device to the local machine of the backup display device according to the input identity identifier, and displays the number of copied display files "5" and the prompt message "OK" indicating successful acquisition of display files on the display screen (this prompt message is displayed in response to the successful acquisition signal). Then the backup display device enters a black screen state.

[0091] After staff confirmed that the backup display device had acquired the required display files, the reserve team member returned the backup display device to the performance area and replaced the malfunctioning display device in its performance position.

[0092] When the performance reaches the point where the display file can begin playing, the signal transmitting device of the splicing screen system sends an excitation signal, and the backup display device responds to the excitation signal to synchronously display the image with other display devices.

[0093] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
