For example, a process, method, system, product or device that includes a series of steps or modules is not limited to the listed steps or modules, but optionally further includes other steps or modules not listed, or optionally further includes other steps or modules inherent to these processes, methods, products or devices.

Rather, the use of words such as "exemplary" or "for example" is intended to present concepts in a specific manner.

[0030] Currently, when a display screen composed of different splicing display units displays video resources, an external device can be used to control each splicing display unit to display a partial resource of the video resource, so that the display screen can display the complete video resource. Exemplarily, as Figure 1 shown, a laptop 101 can send a video to an external device 102, and the external device 102 can be a two-in-one splicing control device capable of realizing hybrid loading of LED and LCD. Then, the external device 102 can split the video and send the split video to the LCD screen 103, the LED screen 104, and the LCD screen 105. Among them, the LED screen 104 is located between the LCD screen 103 and the LCD screen 105.

[0031] However, the cost of the external device is relatively high, resulting in a relatively high cost when a display screen composed of different splicing display units displays video resources. Moreover, the external device is inconvenient to carry and cannot achieve integrated application.

[0032] In view of the above technical problems, an embodiment of the present application provides a splicing processing device. The splicing processing device is integrated into a display screen, and the display screen includes multiple types of splicing display units. The splicing processing device is configured to obtain a video to be displayed, and split the video to be displayed to obtain multiple sub-videos.

In this way, the video can be split by the splicing processing device, and each splicing unit can be controlled to display the corresponding sub-video, so that the display screen can completely and seamlessly display the video to be displayed. Moreover, since the splicing processing device is integrated into the display screen, the display screen and the splicing processing device are integrated for application, reducing the usage cost.

[0037] In some embodiments, the display device 201 further includes a video source module, in which multiple video resources are stored, and the multiple video resources include the video to be displayed.

[0038] In other embodiments, the display system further includes: an electronic device 202. The electronic device 202 is configured to transmit the video to be displayed to the display device 201, that is, the electronic device 202 is a video source device. Moreover, the electronic device 202 can also transmit control parameters (such as splitting parameters) to the display device 201 to control the display device 201 to display the video to be displayed, and the control parameters are used to control the display state of the video to be displayed. For example, the control parameters may include: resolution parameters, brightness parameters, color parameters, etc.

[0039] It should be noted that the embodiments of the present application do not limit the electronic device 202. For example, the electronic device may be a laptop computer, a tablet computer, a mobile phone, etc.

[0040] The embodiments of the present application will be specifically described below with reference to the accompanying drawings of the specification.

[0041] As Figure 2 shown, a display device provided by an embodiment of the present application, the display device 201 includes: a splicing processing device 203 and multiple types of splicing display units 204. Among them, the splicing processing device 203 is connected to each splicing display unit 204.

[0042] It should be noted that the embodiments of the present application do not limit the number of the splicing display units 204. For example, the display device 201 may include 3 splicing display units 204. For another example, the display device 201 may include 5 splicing display units 204. For another example, the display device 201 may include 7 splicing display units 204.

[0043] In some embodiments, the multiple types of splicing display units 204 may include: LCD splicing display units and LED splicing display units.

[0044] Exemplarily, the multiple types of splicing display units 204 may include: two LCD splicing display units and one LED splicing display unit, and the LED splicing display unit is located in the middle of the two LCD splicing display units. The display device may be a display screen composed of two LCD splicing display units and one LED splicing display unit.

[0045] Among them, the splicing processing device 203 includes a video output interface. The splicing processing device 203 can be connected to the splicing display unit 204 through the video output interface.

[0046] In an embodiment of the present application, the splicing display units 204 of multiple types include: an LCD splicing display unit and an LED splicing display unit. The video output interface includes: a video type interface and / or a network type interface.

The splicing processing device 203 can be connected to the LED splicing display unit through the network type interface and a network cable. Or, the splicing processing device 203 can be connected to the LED splicing display unit through the video type interface.

[0048] Exemplarily, the video type interface can include at least one of the following: HDMI, high-definition digital display interface V-BY-ONE interface, DisplayPort (DP) interface, etc.

[0049] It should be noted that the number of video output interfaces in the embodiment of the present application is not limited. For example, the number of video output interfaces is 3, 4, 5, etc. For example, the video output interface includes 2 video type interfaces and 1 network type interface. Or, the video output interface includes 3 video type interfaces. And, the number of a type of splicing display unit can be one or more. For example, the display screen is composed of two types of splicing display units, namely an LED splicing display unit and an LCD splicing display unit, where the number of LED splicing display units is 1 and the number of LCD splicing display units is 2.

[0050] In an embodiment of the present application, the splicing processing device 203 is configured to obtain a video to be displayed, and split the video to be displayed to obtain multiple sub-videos. The Nth frame of the video to be displayed includes the Nth frames of multiple sub-videos, where N is a positive integer, and one sub-video corresponds to one splicing display unit.

[0051] Exemplarily, as Figure 3 shown, the splicing processing device 203 can split the video frame 301 into video sub-frames 302, 303, and 304. Among them, the video sub-frame 302 corresponds to the splicing display unit a, the video sub-frame 303 corresponds to the splicing display unit b, and the video sub-frame 304 corresponds to the splicing display unit c.

[0052] In an embodiment of the present application, the splicing processing device 203 is further configured to send corresponding sub-videos to each of the splicing display units 204 of multiple types, so that the sub-videos displayed by the multiple types of splicing display units 204 are spliced into a video to be displayed. The splicing display unit 204 is configured to receive the multiple sub-videos sent by the splicing processing device and display the sub-videos corresponding to the splicing display unit 204, so that the sub-videos displayed by the multiple types of splicing display units 204 are spliced into a video to be displayed.

[0053] Optionally, the splicing processing device 203 can also perform synchronization processing on the multiple sub-videos, so that the multiple types of splicing display units 204 synchronously display the corresponding sub-videos.

[0054] Exemplarily, the splicing processing device 203 can implement the synchronization of multiple sub-videos through a hardware synchronization signal (such as a High Definition Multimedia Interface (HDMI) signal, a Digital Visual Interface (DVI) signal, etc.) or a software synchronization protocol (such as a Network Device Interface (NDI), a Secure Reliable Transport (SRT), etc.). For example, frame synchronization, time code synchronization, and display area synchronization of multiple sub-videos are achieved.

[0055] Optionally, the splicing processing device 203 is further configured to adjust the sub-videos displayed by the splicing display unit.

[0056] Exemplarily, the splicing processing device 203 can perform delay adjustment according to the number of video frames (such as 1 frame) and according to time (such as microseconds), such as delaying the playback of sub-video a by one frame.

[0057] Based on the above technical solution, the splicing processing device is integrated into the display screen, and the display screen includes multiple types of splicing display units. The splicing processing device is configured to obtain a video to be displayed and segment the video to be displayed to obtain multiple sub-videos. The Nth frame video of the video to be displayed includes the Nth frame videos of the multiple sub-videos, where N is a positive integer, and one sub-video corresponds to one splicing display unit. The splicing display unit is further configured to send corresponding sub-videos to each of the multiple types of splicing display units. In this way, the video can be segmented by the splicing processing device, and each splicing unit can be controlled to display the corresponding sub-video, so that the display screen can completely and seamlessly display the video to be displayed. Moreover, since the splicing processing device is integrated into the display screen, the integration application of the display screen and the splicing processing device is completed, reducing the usage cost.

[0058] In a possible implementation, the driving module is integrated on the splicing processing device, and the splicing processing device includes a driving module, which is respectively connected to the image processing module and the splicing display unit.

[0059] In another possible implementation, the driving module is connected to the LCD splicing display unit. The driving module is used to drive the LCD splicing display unit to display the corresponding sub-video.

[0060] Exemplarily, the driving module can be a liquid crystal display driving chip (TCON).

[0061] In some embodiments, the splicing processing device 203 further includes: a video input interface. The video input interface is used to receive the video to be displayed sent by the video source module. Among them, the video source module is connected to the splicing processing device 203 through the video input interface.

[0062] In the embodiments of the present application, the video source module is located inside the display device 201, or the video source module is located outside the display device 201. The video source module is used to connect to the video input interface of the splicing processing device 203 and send the video to be displayed to the splicing processing device 203.

[0063] Exemplarily, if the video source module is located outside the display device (such as the electronic device 202), the video source module can send the video to be displayed to the display device through the video input interface. Or, if the video source module is located inside the display device, the video source module is connected to the splicing processing device (the video input interface is not shown in the figure), and the video source module can send the video to be displayed to the display device through the video input interface.

[0064] Based on the above technical solution, the video source module is located inside the display device, or the video source module is located outside the display device. The splicing processing device further includes: a video input interface and a video output interface, and the video input interface is used to receive the video to be displayed sent by the video source module. In this way, the display device can obtain internal video resources or external video resources, enriching the way of obtaining video resources.

[0065] In some embodiments, the number of splicing processing devices is multiple, and the multiple splicing processing devices are connected to each other in pairs. One splicing processing device corresponds to a group of different types of splicing display units.

[0066] In a possible implementation, the multiple splicing processing devices include: a host splicing processing device and a slave splicing processing device. The host splicing processing device is used to send a cascading synchronization signal to the slave splicing processing device. The slave splicing processing device is used to synchronize the multiple obtained sub-videos based on the cascading synchronization signal to obtain the processed multiple sub-videos, so as to synchronize between the groups of splicing units corresponding to the multiple splicing processing devices.

[0067] Exemplarily, the multiple splicing processing devices include: a splicing processing device a and a splicing processing device b. The splicing processing device a corresponds to the splicing display units 1-3, and the splicing processing device b corresponds to the splicing display units 4-6. Through the cascaded synchronization signal, it is possible to control the sub-videos displayed by the splicing display units 1-3 to be synchronized with the sub-videos displayed by the splicing display units 4-6, such as frame synchronization, time code synchronization, and display area synchronization, etc.

[0068] It can be understood that when there are multiple splicing processing devices in the display device, by transmitting the cascaded synchronization signal between the multiple splicing processing devices, it is possible to control the splicing display units in each group to be synchronized, so that the display screen can display the complete video to be displayed.

[0069] The following is a specific introduction to the splicing processing device.
