In this embodiment, according to the working mode, the M available display units may be used to display data of the same page, or each display unit may display data of different pages. When M available display units are used to display data of the same page, the data blocks of the same page are divided into M sub-blocks, and each display unit displays one sub-block, which is equivalent to combining M available display units into A large screen is displayed. Specifically, the decoding chip of the mobile terminal may decode and acquire the data block of the same page, and then the data block of the same page is divided into M sub-blocks by the screen splicer of the mobile terminal, and finally the sub-data block and the available display are determined by the matrix switcher. The correspondence of the units.

When each display unit is used to display data of different pages, it is necessary to separately obtain data of different pages, so that the user can browse different pages at the same time. For example, when a user reads an e-book, the user can display different pages simultaneously using a plurality of display units, and can also avoid frequent page turning operations by the user, and multiple pages are simultaneously displayed, so that the user can compare the contents of different pages. Alternatively, when the user uses the WeChat chat process, the user can open multiple chat windows at the same time, and each display unit is used to display a chat window, so that the user can timely understand the chat content in each chat window, and the prior art user must pass If the user needs to input the chat content, the chat window needs to be performed. Switch to the main display unit. Decoding chip Decoding to obtain data of different pages, and then, the matrix switcher determines the correspondence between the data of different pages and the available display units.

Step 104: The mobile terminal sends the to-be-displayed data of the M available display units to the corresponding available display unit for display.

After determining, by the mobile terminal, the data to be displayed of each available display unit, the communication component may send the data to be displayed of each available display unit to the available display unit for display according to the correspondence determined by the matrix switcher, if multiple The available display unit is used to display the data of the same page, and the matrix switcher also needs to ensure that multiple available display units can be displayed simultaneously, for example, when playing a video. If a plurality of available display units respectively display data of different pages, each display unit can be displayed independently without synchronization. The communication component of the mobile terminal transmits the data to be displayed of each auxiliary display unit to each auxiliary display unit, and also transmits the data to be displayed of the main display unit to its own display screen for playing.

The terminal determines the to-be-displayed data of the M available display units according to the configuration information of the main display unit and the N-1 auxiliary display units, and sends the to-be-displayed data of the M available display units to the corresponding available display unit for display. The method realizes multi-screen display by using a plurality of auxiliary display units on the screen protector to display data together with the mobile terminal, and the mobile terminal and the protective cover are detachable, and are convenient for the user to carry.

On the basis of the embodiment shown in FIG. 6, the embodiment of the present invention provides a detailed description of the solution of the first embodiment, and FIG. 7 is a flowchart of the multi-screen display method according to the second embodiment of the present invention. The method provided in this embodiment includes the following steps:

Step 201: The mobile terminal establishes a connection with the protection sleeve.

The mobile terminal can detect whether a protective cover is connected to the mobile terminal.

Step 202: The mobile terminal sends a request message to the N-1 auxiliary display units of the protective cover.

The request message is used to determine the working state of each auxiliary display unit.

Step 203: Each auxiliary display unit of the protective cover returns a response message to the mobile terminal.

After receiving the request message, the simple processor of each auxiliary display unit generates a response message in response to receiving the request message, and transmits the response message to the mobile terminal through the communication component.

Step 204: The mobile terminal determines M available display units according to the response message returned by each auxiliary display unit.

If the mobile terminal does not receive a response message returned by a display unit within a preset time, it is determined that the display unit is unavailable.

Step 205: The mobile terminal receives a compressed file of data of the same page transmitted by the server.

The data of the same page may be multimedia data, text data, webpage data, etc., and the multimedia data is, for example, video data and audio data.

Step 206: The mobile terminal decodes the compressed file of the data of the same page to obtain a playable data block.

The mobile terminal receives the compressed file and cannot directly display it. Therefore, the decoding chip decodes the compressed file to obtain a playable data block. For example, for video data, the decoding chip can obtain a playable image data block and a sound data block by decoding, and send the image data block to the picture splicer.

Step 207: The mobile terminal divides the data block of the same page into M sub-blocks according to the working mode.

In this embodiment, it is assumed that the working mode indicates that the N display units simultaneously display the data of the same page. Therefore, the screen splicer of the mobile terminal divides the data block of the same page into M sub-blocks according to the working mode, where the same The data block of the page is a playable data block. For example, for video data, an image signal of video data is divided into M sub-blocks.

Step 208: The mobile terminal determines a correspondence between the M sub-blocks and the M available display units according to the order of the M sub-blocks and the positional relationship of the M available display units.

This step is performed by a matrix switcher of the mobile terminal, which determines which display unit displays which sub-block of data. For example, there are three display units, and the video data is divided into three sub-blocks from left to right. The numbers from left to right of the three display units are 1, 2, and 3, and the display unit No. 1 is used for display. The leftmost sub-block, the No. 2 display unit is used to display the middle sub-block, and the No. 3 display unit is used to display the rightmost sub-block.

Step 209: The mobile terminal sends the M sub-data blocks to the corresponding available display unit for display according to the corresponding relationship.

The M available display units may also include the main display unit or may not include the main display unit.

Step 210: The M available display units return a receiving confirmation message to the mobile terminal.

After receiving the sub-block, the available display unit generates a reception confirmation message and transmits a reception confirmation message to the mobile terminal.

Step 211: The M available display units simultaneously display the received sub-blocks.

Of course, the M available display units can also be displayed at different times, and at the same time allow a certain error.

FIG. 8 is a schematic diagram of a display effect of the protective cover. As shown in FIG. 8, the video data block is divided into three sub-blocks, which are respectively displayed by three display units, assuming that the number of three sub-blocks is from left to right. The order of the right is A, B, and C. The number of the three display units is 1, 2, and 3 from left to right, then the display unit 1 corresponds to the display sub-block A, and the display unit 2 corresponds to the display sub-block B, and the display unit 3 corresponding to the display sub-block C, three display units constitute a large screen. When the user rotates the protective sleeve by 180 degrees, the correspondence between the sub-block and the display unit also changes. After the rotation, the display unit 3 is at the leftmost end, and the display unit 1 is at the rightmost end. At this time, the display unit 3 correspondingly displays the sub-block A. The content displayed by the display unit 2 remains unchanged as the sub-block B, and the display unit 1 corresponds to the display sub-block C. In a specific implementation, the mobile terminal uses its own sensor to detect the angle at which the mobile terminal is rotated and rotated, and then controls the matrix switcher to adjust the correspondence between the display unit and the sub-block.

In this embodiment, the mobile terminal determines M available display units according to the working states of the main display unit and the N-1 auxiliary display units, and divides the received data blocks of the same page into M sub-blocks according to the working mode. And determining the correspondence between the M sub-blocks and the M available display units according to the order of the M sub-blocks and the positional relationship of the M available display units. Finally, according to the correspondence, the M sub-blocks are sent to the corresponding available. The display unit is displayed. In the method, the data block of the same page may be divided into a plurality of sub-data blocks, and each display unit displays one sub-data block, thereby combining the plurality of display units into one large-screen display unit, thereby increasing the screen of the mobile terminal. .

Optionally, the working mode in the second embodiment may also indicate that one of the display units displays the profile information of the data of a certain page, and indicates that the other display units jointly display the data of the page. For example, for video information, profile information of video content and video can be simultaneously displayed on a large screen in which a plurality of display units are combined. Correspondingly, the mobile terminal divides the received data block of the same page into M-1 sub-blocks according to the working mode, and obtains profile information of the data of the same page, and then determines an available display unit corresponding to the profile information according to the working mode. The available display unit corresponding to the profile information may be the display unit on the far side, so as to avoid dividing the data of the same page.

The mobile terminal is also based on the order of M-1 sub-blocks and the position of the remaining M-1 available display units. And determining a correspondence between the M-1 sub-blocks and the remaining M-1 available display units, and the remaining M-1 available display units are available display units other than the available display units corresponding to the profile information, and finally, According to the correspondence, the M-1 sub-blocks are sent to the corresponding available display unit for display, and the profile information is sent to the available display unit corresponding to the profile information for display. FIG. 9 is a schematic diagram showing another display effect of the protective cover. As shown in FIG. 9, the two display units on the left side are used for displaying video content, and the rightmost display unit is used for displaying profile information of the video.

Optionally, the working mode in this embodiment may also instruct the N display units to display data of different pages. Correspondingly, the mobile terminal determines data of M different pages according to the working mode, and then determines data of the M different pages. The correspondence between the M available display units, and finally, the data of the M different pages is sent to the corresponding available display unit for display according to the corresponding relationship. For example, there are three display units, the display unit 1 is for displaying a WeChat page, the display unit 2 is for displaying a QQ page, and the display unit 3 is for displaying a Taobao page.

In an embodiment of the present invention, as shown in FIG. 3, the protective cover includes three mounting units, wherein the first mounting unit is connected to the mobile terminal, the second mounting unit is mounted with the second display unit, and the third mounting unit A third display unit is installed. The user can control the terminal by manipulating the second display unit and/or the third display unit. Specifically, taking the second display unit as an example, the structure includes the structure shown in FIG. 5, wherein the display screen is used to acquire an operation gesture of the user on the second display unit, and the simple processor acquires the operation gesture reported by the display screen. Relevant parameters, such as coordinate values, gesture types, etc., determine the user's operating gestures. In one possible implementation, the simple processor transmits the operation gesture to the mobile terminal via the communication component, and the processor of the mobile terminal performs a corresponding operation according to the operation gesture, and displays the display result on different display units. In one possible implementation, the operation corresponding to the operation gesture can be directly performed by the simple processor, and the operation result is displayed on the corresponding display unit, as the processing capability of the simple processor allows.

In one embodiment of the invention, the protective cover has been carried with a mobile terminal and two display units. In one application scenario, as shown in Figure 8, the user views the movie in a horizontal position, such as watching a movie at 180 degrees, i.e., where the display of the terminal is a vertical screen. In an application scenario, the user can rotate the protective case as shown in FIG. 8 and rotate it to a vertical position, that is, watching the movie at an angle of 270 degrees or 90 degrees, that is, when the display screen of the terminal is a horizontal screen. . In the foregoing two application scenarios, the terminal may receive the media stream from the received media stream to the media stream processing of the screen splicer and the matrix switcher, and may refer to the foregoing processing flow. In an application scenario, the embodiment supports a situation in which the rotation of the protective cover causes the video playback direction to rotate. Assuming that the M display units in the initial state display the data to be displayed in the first direction, when the protection sleeve rotates, the mobile terminal acquires a direction switching instruction input by the user, and the direction switching instruction is used to switch the display direction of the mobile terminal to the second direction, and move The terminal generates display data in the second direction according to the direction switching instruction, and the M available display units display the display data in the second direction in the second direction. For example, at the first moment, the terminal on the protective cover and the two display units display the movie played in the first direction (first direction); at the second moment, the sensor of the terminal detects that the direction in which the user holds the terminal changes, and the terminal The processor obtains the direction display information of the display screen. After the decoding chip parses the media stream, according to the display direction (second direction) of the current display screen, the screen splicer divides the complete image signal parsed by one decoding chip into three blocks. The three display units assigned to the protective cover are displayed; the matrix switcher transmits the signals divided by the screen splicer to the three displays according to the display directions of the current three display units, so that the display unit on the protective cover is displayed. When the direction is rotated, the direction of the played video can also change as the display direction of the display unit changes, thereby improving the user experience. When the user rotates the protective sleeve by 180 degrees, the screen splicer does not need to re-divide the image signal, and the matrix switcher only needs to adjust the display data on each display unit according to the direction, that is, adjust the correspondence between the display unit and the display data.
