It can be understood that, in fig. 1, it is illustrated that four side surfaces of the screen main body 102 are respectively provided with one splicing element, in practical applications, one splicing element may be provided on at least one side surface of one screen main body, for example, one splicing element may be provided on one side surface, two opposite side surfaces or two adjacent side surfaces may be provided with one splicing element respectively, or three adjacent side surfaces may be provided with one splicing element respectively, in addition, the number of the splicing elements provided on the side surfaces is not limited to one, for example, two splicing elements are provided on a long side of the screen main body 102, and in practical applications, the setting positions and the setting number of the splicing elements on the side surfaces may be determined according to needs, and are not limited herein.
It is understood that, for the splicing members arranged at the side surfaces of the screen main body, at least one side surface with the splicing member can be used for splicing with one side surface with the splicing member of other screen main bodies, and not all the splicing members are required to be spliced, as shown in fig. 1, although the splicing members are provided on four sides of the two screen bodies, at the time of splicing, the splicing member D1 of one screen body and the splicing member B2 of the other screen body are used to be matched, thereby forming the display screen 103 shown in fig. 1, in practical applications, if there are other screen bodies, the splicing element on the other screen body may be matched with the splicing element D2 on the screen body to realize splicing, or matched with the splicing element B1 on the screen body to realize splicing.
In the embodiment of the present application, the splicing element may be a magnetic adsorption element, wherein the magnetic adsorption element has an adsorption capacity, and two magnetic adsorption elements will attract each other and adsorb together when approaching a certain distance (e.g. 3cm), and have a certain adsorption force, if a user needs to separate the two magnetic adsorption elements, the two magnetic adsorption elements can be separated by providing a pulling force opposite to the adsorption force and greater than the adsorption force, it can be understood that the magnetic adsorption element may be embedded in the side surface of the screen main body 102, so that the magnetic adsorption element on one side surface of one screen main body matches with the magnetic adsorption element on one side surface of the other screen main body, and after adsorbing together, the side surfaces of the two screen main bodies can be attached to realize splicing, and thus the spliced display screen gap is small, the influence on the picture display is small, and the user can watch the picture conveniently.
In the embodiment of the present application, each screen main body further includes a control device and at least one communication interface, where the control device is used for performing interactive control of signaling and data between the screen main body where the control device is located and other screen main bodies. The control device is arranged inside the screen main body and connected with the communication interfaces, for example, if the number of the communication interfaces is 4, the control device is respectively connected with the 4 communication interfaces, it should be noted that the number of the communication interfaces is the same as the number of the splicing elements on the side surface of the screen main body, and the communication interfaces and the splicing elements have a one-to-one correspondence relationship, wherein, when the communication interface on one screen main body is used for splicing the screen main body with another screen main body, the communication interface can be butted with the communication interface on the other screen main body, and a communication line between the two screen main bodies is connected through the two butted communication interfaces, so that interaction of data and signaling between the two spliced screen main bodies can be realized through the communication line.
Optionally, for the communication interface and the splicing element having the corresponding relationship on the same side of the screen main body, the communication interface and the splicing element may be separated by a preset distance, for example, 3cm or 5cm, in this case, after the splicing element completes splicing, the spliced screen main body further needs the communication interface to perform position pairing, so that a communication line between the spliced screen main bodies can be connected. Or, for the communication interface and the splicing element having the corresponding relationship on the same side of the screen main body, a through hole may be provided in the splicing element, and the corresponding communication interface is provided in the through hole, so that the positions between the communication interface and the splicing element are overlapped. Taking the first screen main body and the second screen main body as an example, when the first splicing element of the first screen main body and the second splicing element of the second screen main body are spliced, the first communication interface in the through hole of the first splicing element is butted with the second communication interface in the through hole of the second splicing element, and a communication line is connected.
It should be noted that, the communication lines connected by the communication interfaces are used for data and signaling interaction between the screen main bodies, and for display control of the display screen formed after splicing, the host main body needs to perform unified control, and in this case, the host main body needs to have wireless communication connection with the plurality of spliced screen main bodies included in the display screen, so that the host main body can divide the picture to be displayed and send the picture to the corresponding screen main body through the wireless communication connection. It can be understood that, for a first screen body of an electronic device, if a second screen body is spliced with the first screen body through a splicing element, but the second screen body does not establish a wireless communication connection with a host body of the electronic device, it indicates that the host body still cannot control the display of the second screen body, and in this case, the second screen body cannot be considered as an extended screen.
