[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0034] In order to play display content such as a display video, an image, etc., a single display terminal is generally used, but in some scenarios, in order to expand the display area, a plurality of display terminals need to be spliced to display the same display content by using the plurality of display terminals, wherein the same content is involved in segmentation, and currently, manual setting is generally used, resulting in low screen splitting efficiency. In order to solve the problem of lack of automatic screen splitting technology in the prior art, the present application provides a screen splitting display system, as shown in Figure 1 The screen splitting display system includes a screen splitting processing device 102 and at least two display terminals 104, wherein the screen splitting processing device 102 is connected (for example, wirelessly connected) with each display terminal 104. The screen splitting processing device 102 is used to segment and transmit the display content to each display terminal 104. In one example, the screen splitting processing device is used as a data source of the display content, and can also segment and distribute the display content to each display terminal. For example, a screen splitter is integrated on a mobile terminal. In another example, the screen splitting processing device includes a processing device and a screen splitter connected with the processing device. The processing device is used as a data source of the display content and segments the display content. The screen splitter is used to transmit data between the processing device and the display terminal. The display terminal 104 is used to display content, which can be but is not limited to a mobile phone, a tablet computer, and a notebook computer. The number of display terminals is at least two. Each display terminal is arranged according to a certain rule, for example, in a horizontal one-dimensional array, in a vertical one-dimensional array, or in a matrix (as shown in Figures 2 to 4 ).

[0035] In the actual screen splitting process, the screen splitting processing device 102 sends corresponding interconnection signals to each display terminal 104. Each display terminal 104 emits a sound wave signal to the remaining display terminals 104 according to the corresponding interconnection signal. Each display terminal 104 obtains the relative position of itself and the remaining display terminals 104 based on the collected sound wave signal. Each display terminal 104 returns the relative position to the screen splitting processing device 102. The screen splitting processing device 102 segments the display content into sub-content corresponding to each display terminal according to the relative positions, and transmits each sub-content to the corresponding display terminal 104, thereby realizing the cutting of the display content by the cooperation of the screen splitting processing device 102 and each display terminal 104, and ensuring that each display terminal 104 displays the corresponding content.

[0036] In order to describe the process of the screen splitting display system of the present application in detail, the screen splitting display method of the present application will be described in detail below in combination with the drawings:

[0037] As shown in Figure 5 , a screen splitting display method is provided, including the following steps:

[0038] Step S510, sending corresponding interconnection signals to each display terminal; each interconnection signal is used to instruct the corresponding display terminal to feedback a relative position; each relative position is obtained by each display terminal based on a collected sound wave signal, and is a relative position of each display terminal to the rest of the display terminals; each sound wave signal is emitted by each display terminal to the rest of the display terminals according to the corresponding interconnection signal.

[0039] It should be noted that the split-screen processing device sends corresponding interconnection signals to each display terminal to inform the display terminal that the to-be-displayed content needs to be displayed. In order to ensure that the to-be-displayed content can be reasonably divided, the interconnection signal controls the display terminal to collect the relative position, and the display terminal feeds back the positioning information to the split-screen processing device.

[0040] Each relative position is obtained by the corresponding display terminal collecting sound wave signals emitted by the rest of the display terminals. In order to realize positioning by using sound wave signals, a sound wave receiving unit and a sound wave emitting unit are arranged on each display terminal; the sound wave receiving unit and the sound wave emitting unit are connected to the controller of the display terminal; the sound wave emitting unit is used to emit sound wave signals; and the sound wave receiving unit is used to receive sound wave signals to realize positioning between each display terminal. In one example, the sound wave receiving unit and the sound wave emitting unit are external components (the sound wave receiving unit and the sound wave emitting unit can be integrated into a sound wave transceiver device) and are plugged into the display terminal; in another example, the microphone of each display terminal is integrated with the sound wave receiving unit; and the sound box of each display terminal is integrated with the sound wave emitting unit, that is, the sound wave receiving unit is placed in the microphone of the display terminal; and the sound wave emitting unit is placed in the sound equipment of the display terminal.

[0041] The sound wave signal is used to indicate the relative position of the signal receiving side to the signal emitting side. For example, the display terminals include a No. 1 display terminal, a No. 2 display terminal and a No. 3 display terminal, the No. 1 display terminal emits a sound wave signal which is received by the No. 2 display terminal and the No. 3 display terminal, and the No. 2 display terminal and the No. 3 display terminal can obtain the relative position of the No. 1 display terminal to themselves, and the same applies to the No. 2 display terminal and the No. 3 display terminal. The No. 2 display terminal emits a sound wave signal which is received by the No. 1 display terminal and the No. 3 display terminal, and the No. 1 display terminal and the No. 3 display terminal can obtain the relative position of the No. 2 display terminal to themselves; and the No. 3 display terminal emits a sound wave signal which is received by the No. 1 display terminal and the No. 2 display terminal, and the No. 1 display terminal and the No. 2 display terminal can obtain the relative position of the No. 3 display terminal to themselves.

[0042] In addition to positioning by using sound wave signals, the following two ways of realizing positioning are introduced:

[0043] In an implementation, the relative positions are obtained according to the geographic position information, the interconnection signal is used to instruct the display terminal to start the positioning system to collect the geographic position information as the positioning information, and the split-screen processing device calculates the geographic positions of the display terminals according to the geographic position information. The positioning system can be a GPS (Global Positioning System) system, a Beidou system, or the like.

[0044] In another implementation, each relative position is obtained by collecting the positioning signal transmitted by the rest of the display terminals. In order to realize positioning by using the positioning signal, each display terminal is provided with a device for transmitting the positioning signal and a device for collecting the positioning signal. The positioning signal is used to indicate the relative position of the signal receiving side to the signal transmitting side. For example, the display terminals include a No. 1 display terminal, a No. 2 display terminal, and a No. 3 display terminal. The No. 1 display terminal transmits the positioning signal which is received by the No. 2 display terminal and the No. 3 display terminal, and the No. 2 display terminal and the No. 3 display terminal can obtain the relative position of the No. 1 display terminal to itself. Similarly, the No. 2 display terminal transmits the positioning signal which is received by the No. 1 display terminal and the No. 3 display terminal, and the No. 1 display terminal and the No. 3 display terminal can obtain the relative position of the No. 2 display terminal to itself. The No. 3 display terminal transmits the positioning signal which is received by the No. 1 display terminal and the No. 2 display terminal, and the No. 1 display terminal and the No. 2 display terminal can obtain the relative position of the No. 3 display terminal to itself.

[0045] For example, the positioning signal can be a vibration signal or a light signal. When the positioning signal is a vibration signal, the corresponding display terminal is provided with a vibrator and a vibration detector. When the positioning signal is a light signal, the corresponding display terminal is provided with a light emitter and a light detector.

[0046] When the positioning signal is a vibration signal, the display terminal includes a vibrator and a vibration detector. The vibrator and the vibration detector are connected to the controller of the display terminal. The vibrator is used to transmit the vibration signal, and the vibration detector is used to receive the vibration signal. The vibrator is arranged on the display terminal to transmit the vibration signal, and the vibration detector is arranged on the display terminal to receive the vibration signal, so as to realize the positioning between the display terminals.

[0047] When the positioning signal is a light signal, the display terminal includes a light emitter and a light detector. The light emitter and the light detector are connected to the controller of the display terminal. The light emitter is used to transmit the light signal, and the light detector is used to receive the light signal. The light emitter is arranged on the display terminal to transmit the light signal, and the light detector is arranged on the display terminal to receive the light signal, so as to realize the positioning between the display terminals.

[0048] In order to obtain the positioning information in sequence and avoid the mutual influence between the sound wave signals emitted by each display terminal at the same time, in an example, each interconnection signal includes a countdown time length, and each countdown time length is different, that is, the countdown time length separates the sound wave signals emitted by each display terminal, specifically, each countdown time length is used to instruct the corresponding display terminal to emit a sound wave signal to the remaining display terminals when the countdown time length is completed, so that each display terminal obtains the positioning information based on the sound wave signal. When the sound wave signal is a sound wave signal, the countdown time length is used to instruct the display terminal to start the sound wave emission unit on the display terminal to emit a sound wave signal when the countdown time length is completed, and the sound wave receiving unit is always in a receiving state; when the sound wave signal is a vibration signal, the countdown time length is used to instruct the display terminal to start the vibrator on the display terminal to emit a vibration signal when the countdown time length is completed, and the vibration detector is always in a receiving state; when the sound wave signal is a light signal, the countdown time length is used to instruct the display terminal to start the light emitter on the display terminal to emit a light signal when the countdown time length is completed, and the light detector is always in a receiving state.

[0049] For example, the display terminal includes a No. 1 display terminal, a No. 2 display terminal, a No. 3 display terminal and a No. 4 display terminal; the countdown time length corresponding to the No. 1 display terminal is 50 ms (milliseconds), the countdown time length corresponding to the No. 2 display terminal is 10 ms, the countdown time length corresponding to the No. 3 display terminal is 20 ms, and the countdown time length corresponding to the No. 4 display terminal is 70 ms.

[0050] In an example, the countdown time lengths can form an arithmetic sequence, wherein the common difference of the arithmetic sequence is 20 ms to 40 ms. For example, an arithmetic sequence of 30 ms, 60 ms, 90 ms, 120 ms.

[0051] In another example, the split-screen processing apparatus sends the corresponding interconnection signals to each display terminal at different time points. In this example, the split-screen processing apparatus actively stagger the time points to send the interconnection signals to each display terminal, avoiding sending the interconnection signals to each display terminal at the same time, thereby avoiding confusion in obtaining the relative positions of each display terminal. In order to send the interconnection signals in order, the split-screen processing apparatus sends the corresponding interconnection signals to one display terminal every preset time length until it completes sending the corresponding interconnection signals to all display terminals. Wherein, the preset time length is 20 ms to 40 ms, for example, 25 ms, 35 ms, etc.

[0052] To avoid data transmission confusion and ensure that the split-screen processing device can correctly acquire data, in an example, each interconnection signal sent by the split-screen processing device further includes an information feedback duration; the information feedback duration is greater than or equal to the sum of each countdown duration; and each display terminal sends its relative position with the remaining display terminals to the split-screen processing device when the corresponding information feedback duration is complete. It can be understood that the information feedback duration is used to specify the time for the display terminal to feed back the relative position, and the information feedback duration is greater than or equal to the sum of each countdown duration, so as to ensure that the display terminal collects all the relative positions of itself and the remaining display terminals, and then feeds back all the relative positions to the split-screen processing device. In an example, each information feedback duration is different. In another example, some of the information feedback durations are the same and some are different. In yet another example, each information feedback duration is the same.

[0053] At step S520, the content to be displayed is divided into sub-contents corresponding to the display terminals according to the relative positions, and the sub-contents are transmitted to the display terminals one by one.

[0054] It should be noted that the split-screen processing device divides the content to be displayed into sub-contents equal in number to the display terminals, for example, when the number of display terminals is 3, the content to be displayed is divided into 3 sub-contents.

[0055] After the split-screen processing device acquires the relative positions sent by each display terminal, the split-screen processing device analyzes the relative positions between the display terminals according to the relative positions, and divides the content to be displayed into a corresponding number of sub-contents based on the relative positions, to confirm the division scheme of the content to be displayed, and ensure that each display terminal can display the content to be displayed in its entirety.

[0056] The way of dividing the display content can be various, and one of the following ways is provided:

[0057] The split-screen processing device processes each relative position to obtain a center position corresponding to each display terminal;

[0058] The split-screen processing device acquires size information corresponding to each display terminal, and divides the content to be displayed into sub-contents corresponding to the display terminals according to the size information and the center positions.

[0059] It should be noted that the center position is the display center of the display screen of the display terminal, and the corresponding center positions of each display terminal in the same coordinate system are obtained by analyzing the relative positions.

[0060] The split-screen processing apparatus can obtain the size of each sub-content area by processing the size information. In one example, the size information can be the peripheral size information of the display terminal and the frame size information of the display terminal, and the split-screen processing apparatus can obtain the size information of the display screen by processing the peripheral size information and the frame size information. In another example, the size information is the size information of the display screen of the display terminal. The split-screen processing apparatus maps each center position to the display content, and divides the size of the sub-content area by using the size information. To better understand the scheme of the present application, the following describes a specific embodiment of a sound wave signal (such as Figure 6

[0061] The display terminal includes a No. 1 display terminal, a No. 2 display terminal, a No. 3 display terminal, and a No. 4 display terminal (arranged as Figure 6 The countdown time length is 30 ms, 60 ms, 90 ms, and 120 ms, respectively; the countdown time length corresponding to the No. 1 display terminal is 30 ms, the countdown time length corresponding to the No. 2 display terminal is 60 ms, the countdown time length corresponding to the No. 3 display terminal is 90 ms, and the countdown time length corresponding to the No. 4 display terminal is 120 ms.

[0062] When the countdown time length of 30 ms is up, the sound wave emitting unit on the No. 1 display terminal emits a sound wave signal to the No. 2 display terminal, the No. 3 display terminal, and the No. 4 display terminal; when the countdown time length of 60 ms is up, the sound wave emitting unit on the No. 2 display terminal emits a sound wave signal to the No. 1 display terminal, the No. 3 display terminal, and the No. 4 display terminal; when the countdown time length of 90 ms is up, the sound wave emitting unit on the No. 3 display terminal emits a sound wave signal to the No. 1 display terminal, the No. 2 display terminal, and the No. 4 display terminal; when the countdown time length of 120 ms is up, the sound wave emitting unit on the No. 4 display terminal emits a sound wave signal to the No. 1 display terminal, the No. 2 display terminal, and the No. 3 display terminal; during this period, the sound wave receiving units on the No. 1 display terminal, the No. 2 display terminal, the No. 3 display terminal, and the No. 4 display terminal continuously collect sound wave signals.

[0063] At the end of each round of sound wave emission, the No. 1 display terminal receives sound waves from three directions, and judges that the distances of the three directions relative to itself are (1, 1), (0, 1), and (1, 0), respectively. The No. 1 display terminal immediately returns data to the split-screen processing apparatus.

[0064] ​Similarly, the No. 2 display terminal will send (-1, 0), (0, 1), (-1, 1) data groups to the split-screen processing device, the No. 3 display terminal will send (0, -1), (-1, 1), (0, 1) data groups to the split-screen processing device, and the No. 4 display terminal will send (-1, -1), (0, -1), (-1, 0) data groups to the split-screen processing device. At this time, the split-screen processing device can calculate the relative positions of the four display terminals according to the corresponding data, so as to perform picture separation and corresponding human-computer interaction data processing.

[0065] The split-screen display method of the present application sends corresponding interconnection signals to each display terminal; each interconnection signal is used to instruct the corresponding display terminal to feed back a relative position; each relative position is obtained by each display terminal based on a collected sound wave signal, and is the relative position of each display terminal with respect to the remaining display terminals; each sound wave signal is emitted by each display terminal to the remaining display terminals according to the corresponding interconnection signal.

[0066] According to the relative positions, the to-be-displayed content is divided into sub-contents corresponding to the display terminals one by one, and the sub-contents are transmitted to the display terminals one by one, so as to realize the complete cutting of the to-be-displayed content by the split-screen processing device and the display terminals, and ensure that each display terminal displays the corresponding content. It is convenient to use and has a wide range of applications. It is not limited by cable connection and can be used with a wireless split-screen processing device.
