Optionally, the above M + N identifiers may be displayed in each screen page on the first electronic device.

Fig. 3 is a schematic interface diagram of a screen expansion according to an embodiment of the present invention, as shown in fig. 3 (a), before a screen page is not expanded, a screen page a2 of an electronic device a sequentially displays a hollow circle and a solid circle; a screen page B1 of the electronic device B sequentially displays a solid circle and a hollow circle; a hollow circle and a solid circle are sequentially displayed on a screen page B2 of the electronic device B, and after the electronic device shares a screen page B1 and a screen page B2 with the electronic device a, as shown in (B) in fig. 3, the hollow circle, the solid circle, the hollow circle and the hollow circle are sequentially displayed on a screen page a2 of the electronic device a; sequentially displaying a hollow circle, a solid circle and a hollow circle on a screen page A3 (a screen page B1 of the original electronic equipment B); an open circle, and a solid circle are sequentially displayed on the screen page a4 (screen page B2 of the original electronic device B).

It should be noted that, the above "the target electronic device shares N screen pages with the first electronic device" may be understood that the target electronic device shares N screen pages of the target electronic device with the first electronic device, and specifically includes the following two cases:

case 1: the target electronic equipment shares the N screen pages of the target electronic equipment to the first electronic equipment, and the first electronic equipment shares the screen page of the first electronic equipment to the target electronic equipment.

Case 2: the target electronic equipment shares the N screen pages of the target electronic equipment to the first electronic equipment, and the first electronic equipment does not share the screen page of the first electronic equipment to the target electronic equipment.

Optionally, in the embodiment of the present invention, the electronic device may share one or more screen pages of the plurality of local screen pages of the electronic device.

It will be appreciated that for an electronic device, the number of screen pages that a user can see on the electronic device is equal to the sum of the number of local screen pages plus the number of screens shared by all other electronic devices.

Exemplarily, the electronic device 1 is taken as a first electronic device, and the electronic devices 2 and 3 are taken as target electronic devices. The electronic device 1, the electronic device 2, and the electronic device 3 constitute a screen sharing group. Wherein, before sharing the screen, the electronic device 1 includes 2 local screen pages, which are respectively: screen pages 1-1 and 1-2; before sharing the screen, the electronic device 2 includes 3 local screen pages, which are: screen page 2-1, screen page 2-2, and screen page 2-3; before sharing the screen, the electronic device 3 includes 4 local screen pages, which are: screen page 3-1, screen page 3-2, screen page 3-3, and screen page 3-4.

In the above-described case 1, it is assumed that the electronic device 1 shares the screen page 1-1 and the screen page 1-2, the electronic device 2 shares the screen page 2-2 and the screen page 2-3, and the electronic device 3 shares the screen page 3-2 and the screen page 3-4. The screen page displayed on the local screen of the electronic device 1 after the screen page is expanded may include: screen page 1-1, screen page 1-2, screen page 2-3, screen page 3-2, and screen page 3-4. The screen page displayed on the local screen of the electronic device 2 after the screen page is expanded may include: screen page 2-1, screen page 2-2, screen page 2-3, screen page 1-1, screen page 1-2, screen page 3-2, and screen page 3-4. The screen page displayed on the local screen of the electronic device 3 after the screen page is expanded may include: screen page 3-1, screen page 3-2, screen page 3-3, screen page 3-4, screen page 1-1 and screen page 1-2, screen page 2-2 and screen page 2-3.

In case 2 described above, it is assumed that the electronic device 1 does not share the screen page, the electronic device 2 shares the screen page 2-1 and the screen page 2-3, and the electronic device 3 shares the screen page 3-3 and the screen page 3-4. The screen page displayed on the local screen of the electronic device 1 after the screen page is expanded may include: screen page 1-1, screen page 1-2, screen page 2-1, screen page 2-3, screen page 3-3, and screen page 3-4. The screen page displayed on the local screen of the electronic device 2 after the screen page is expanded may include: screen page 2-1, screen page 2-2, screen page 2-3, screen page 3-3, and screen page 3-4. The screen page displayed on the screen local to the electronic device 3 after expanding the screen page may include: screen page 3-1, screen page 3-2, screen page 3-3, screen page 3-4, screen page 2-1, and screen page 2-2.

It can be understood that after the first electronic device expands the screen page, if the user slides the screen page on the first electronic device, the user may browse the screen page local to the first electronic device, and may also browse the screen page shared by other expanded devices. The user can flexibly operate the first electronic device through sliding on the first electronic device, and can also operate the first electronic expansion screen page or the electronic device of the screen page.

For example, after the first electronic device receives an operation of a user on an extended screen page through the first electronic device, the first electronic device may record the touch screen event and transmit the touch screen event to the electronic device corresponding to the extended screen page, where the touch screen event may include: coordinate position, trajectory, mapping, etc.

Optionally, after the target electronic device receives the touch screen event sent by the first electronic device, the target electronic device may respond to the touch screen event and transmit a response result to the first electronic device, and the first electronic device may display the response result on the first electronic device. The target electronic device may display the response result of the touch screen event on the screen, or may not display the response result of the touch screen event, which is not specifically limited in the embodiment of the present invention.

It should be noted that the screen page shared by other devices may include all the content on the screen page, or may include part of the content. For example, applications on screen pages, folders, virtual keys, pendant (e.g., weather, time, operator, power), documents, etc. may be included.

The screen expansion method provided by the embodiment of the invention comprises the following steps that firstly, a first electronic device determines that a target electronic device shares N screen pages to the first electronic device, the target electronic device comprises at least one electronic device, and each electronic device in the at least one electronic device at least shares one screen page; then, the first electronic device may display M + N identifiers on the first screen page, where the M + N identifiers are used to indicate M screen pages local to the first electronic device and N screen pages shared by the first electronic device in the extended display mode. The first screen page is one of the M + N screen pages indicated by the M + N identifiers. Under the condition that the target electronic equipment shares N screen pages with the first electronic equipment, the first electronic equipment can expand the N screen pages into the screen pages displayed on the first electronic equipment under the condition that local M screen pages are kept displayed, and M + N marks are displayed on the first screen page to prompt a user to expand the N screen pages.

Optionally, before the foregoing S201, the screen expansion method provided in the embodiment of the present invention may further include S203a, S203b, or S203 c:

s203a, the first electronic device receives a first input, where the first input is to trigger the first electronic device to join a screen sharing group, and the screen sharing group includes the N screen pages.

Further, S201 in the above embodiment may be executed by S201a described below:

s201a, the first electronic device responds to the first input, and N screen pages shared by the target electronic device to the first electronic device are determined.

For example, in a case where the other electronic device initiates screen sharing, the first electronic device may join the screen sharing group by inputting an appointed password, or join the screen sharing group according to a received screen sharing request message. After joining the screen sharing group, a screen page shared by other electronic devices that have joined the screen sharing group may be expanded into the screen page of the first electronic device.

S203b, after the first electronic device initiates the screen sharing, the first electronic device receives first indication information, where the first indication information indicates that the N screen pages join the screen sharing.

Illustratively, after a user triggers a first electronic device to initiate sharing, if the first electronic device joins screen sharing (screen sharing group creation is successful), the first electronic device updates the number of identifiers on a screen page of the first electronic device and adds N screen pages shared by the electronic devices.

S203c, under the condition that the first electronic device has K expanded screen pages, the first electronic device receives a second indication message, the second indication message indicates N-K screen pages to be added into the screen sharing, and K is a positive integer smaller than N.

It should be noted that, after the first electronic device has joined screen sharing (which may be initiated by the first electronic device or initiated by another electronic device), and K screen pages shared by another electronic device have been expanded, one electronic device is joined in the screen sharing group, and the electronic device shares N-K screen pages, the first electronic device may update the number of identifiers on the screen page of the electronic device, and expand the K screen pages shared by the electronic device into the screen page that can be displayed in the first electronic device.

Correspondingly, the other electronic devices in the screen sharing group also add the K screen pages shared by the electronic devices, and the electronic devices add the screen sharing pages shared in the sharing group.

In the embodiment of the invention, the screen sharing and the data interaction can be initiated through non-contact wireless operation (such as Wi-Fi, Bluetooth, NFC, 4G and 5G). When multiple electronic devices establish a screen sharing group, the initiating device may trigger a communication protocol that establishes the screen sharing group. For example, one way to prompt the establishment of a screen sharing group is for the protocol to generate a set of unique codes, and the electronic device to begin establishing a connection after entering the unique code.

Alternatively, the communication protocol for establishing the screen sharing group may be a centralized protocol or an decentralized protocol, where in the case of the communication protocol centralized protocol, the operation information of each electronic device in the screen sharing group on the shared screen page is transmitted to the server of the decision center through the protocol, and then the server of the decision center arbitrates to transfer the operation behavior to the corresponding other electronic device, for example, if the user operates on the screen page 2-1 displayed on the electronic device 1, the electronic device 1 uploads the operation event to the server of the decision center, and the server of the decision center distributes the operation event to the electronic device 2. In the case that the communication protocol is a decentralized protocol, the electronic devices communicate and interact directly with each other. For example, if the user operates on the screen page 2-1 displayed on the electronic device 1, the electronic device 1 and the electronic device 2 directly interact with each other in a communication manner.

It should be noted that when the APP is opened by clicking the icon on the local screen page of the electronic device a, the local APP is opened. When opening the APP on the screen page of the electronic device A originally belonging to the device B with you, the method is equivalent to opening the application of the device B on the device A. This opening may be accomplished for a second on faster network communications, making the APP imperceptible to the user as being on a remote device, such as HTML5 or a fast application mode APP may be opened quickly. The user can conveniently check the APP or the shared file information on other equipment to determine whether the user is interested in obtaining the file or the APP, and when the user exits from the file or the APP of the electronic equipment B, the user can prompt whether the APP needs to be transmitted and installed on the local electronic equipment A.

In the embodiment of the invention, the user can establish the screen sharing group through the third-party application and also can establish the screen sharing group through the system function.

Based on the scheme, the electronic equipment can display the M + N identifications at different occasions, so that the electronic equipment can flexibly share the screen, the identifications on the screen page are updated to prompt a user that the N virtual screens are expanded, and the user can operate the contents in the electronics corresponding to the virtual screens under the condition of displaying the N virtual screens.

In the embodiment of the present invention, in a case where a user triggers the first electronic device to initiate screen sharing, the first electronic device may display content that can be screen shared. After the first electronic device receives the screen sharing request message initiated by the target electronic device, if it receives a group that the user determines to join the screen sharing, the first electronic device may also display the content that can be screen shared. In a case where the user acquires the password for joining the screen sharing group in another manner (that is, other electronic devices may join the screen sharing group by inputting an appointed password in addition to the electronic device initiating the screen sharing), after the user inputs the password for joining the screen sharing group, the first electronic device may also display the content that can be screen shared.

Optionally, before the step S201, the screen expansion method provided in the embodiment of the present invention may further include the following steps S204a to S204 c:

s204a, the first electronic device displays the option to be shared by the first electronic device.

The options to be shared comprise screen page options or screen page options and options of content on the screen page.

It should be noted that, in the embodiment of the present invention, if the option to be shared by the user of the first electronic device is a part of content on the screen, a screen page may be displayed in the other electronic devices participating in screen sharing, and a background of the screen page may be a screen background of the first electronic device where the shared content is located.

S204b, the first electronic device receives a second input.

Wherein the second input may be an input for the user to select the shared content from the options to be shared displayed by the first electronic device.

It will be appreciated that the user may choose to share all of the content in one screen page, or may choose to share some of the content in one screen page.

For example, if the user can select to share all screen pages of the first electronic device, the user can share the 3 screen pages, and the user can select to share 1 or 2 screen pages. Of course, the first electronic device may also select to share a part of content on a certain screen page, for example, select a part of APP in a screen page to share, and select a document in a screen page to share.

S204c, the first electronic device determines the content shared by the first electronic device in response to the second input.

It is understood that the first electronic device may share the screen page selected by the user after the selection is completed.

Based on the scheme, the user can flexibly select the content to be shared according to the requirement, the user can share all screen pages, and the user can also share part of the screen pages.

In an embodiment of the present invention, the first electronic device may add a mark, such as a lightweight annotation User Interface (UI), to the N screen pages, so as to distinguish the N screen pages as screen pages shared by other electronic devices, where for example, a rectangular frame is displayed on a boundary of the screen page shared by the other electronic devices, a virtual frame is added to the entire screen, a "share" is displayed on the screen page shared by the other electronic devices, and the mark is not displayed on the local screen page.

Optionally, indication information is further included on each of the N screen pages shared by the target electronic device; one indication information may be used to indicate the electronic device to which the screen page where the one indication information is located belongs.

It can be understood that, in the case that the first electronic device displays any one of the above N screen pages, the first electronic device may display, at a preset position on the screen page, a name or a device identification code of the electronic device sharing the screen page.

For example, if the screen page a is an electronic device with three pages in the account, the first electronic device may display "three shared screen pages" in the upper right corner of the page a when the first electronic device displays the screen page a on the physical screen.

Based on the scheme, the first electronic device can display the indication information indicating the electronic device to which the screen page belongs on the screen page shared by other electronic devices, so that a user can conveniently determine which electronic device the currently displayed screen page comes from, and the user can perform more accurate operation in the screen sharing process.

Optionally, the first electronic device displays M + N screen pages on a physical screen of the first electronic device from left to right according to a preset rule, where the preset rule may be any one of the following display rules. The user may set the setting according to the requirement, which is not specifically limited in the embodiment of the present invention.

Display rule 1: the first electronic device may display a screen page local to the first electronic device first, and then display a screen page shared by the target electronic device. If the target electronic device comprises a plurality of electronic devices, the electronic devices can be sequentially displayed according to the sequence of adding the sharing.

Display rule 2: the first electronic device may display the screen page shared by the target electronic device first, and then display the screen page local to the first electronic device. If the target electronic device comprises a plurality of electronic devices, the electronic devices can be sequentially displayed according to the sequence of adding the sharing.

And 3, in the case that the target electronic device comprises a plurality of electronic devices, the first electronic device may display the screen page shared by the electronic device which is added in the front of the screen expansion sequence, then display the screen page local to the first electronic device, and then display the screen page shared by the electronic device which is added in the back of the screen expansion sequence.

Based on the scheme, the user can select different display rules to display the local screen page and the expanded screen page according to the requirement, so that the operation of the user in the screen sharing process is more convenient.

Optionally, after the foregoing S201, the screen expansion method provided in the embodiment of the present invention may further include the following S205 and S206:

s205, the first electronic device receives a third input of moving the icon of the first application installed on the first electronic device to the second screen page.

And the second screen page is a screen page shared by the second electronic equipment in the target electronic equipment.

For example, after receiving the third input from the user, the first electronic device may send a request message to the second electronic device, where the request message is used to determine whether the first application is installed in the second electronic device, and the first electronic device may determine whether the first application is installed in the second electronic device according to the confirmation message sent by the second electronic device.

S206, the first electronic device, in response to the third input, performs any one of the following operations T1 to T3 in a case where the first application is not installed in the second electronic device.

T1: the first electronic device sends the installation file of the first application in the first electronic device to the second electronic device.

For example, in a case where an installation file (or a source file) of a first application is included in the first electronic device, the first electronic device may transmit the installation file of the first application in the first electronic device to the second electronic device after receiving the third input, so that the first application is installed on a local screen page of the second electronic device corresponding to the second screen page.

T2: the first electronic equipment triggers the second electronic equipment to download the installation file of the first application.

For example, after the first electronic device receives the third input, the first electronic device may also send a download instruction to the second electronic device, so that the second electronic device triggers the second electronic device to download the installation file of the first application from the second electronic device application mall after receiving the download instruction, and install the installation file according to the installation file.

T3: the first electronic equipment sends prompt information for installing the first application to the second electronic equipment.

For example, after the first electronic device receives the third input, the first electronic device may also send prompt information for installing the first application to the second electronic device, so that the second electronic device may prompt the user whether to install the first application, and after the user determines to install the first application, the second electronic device may receive and install an installation file of the first application from the first electronic device, or may download and install the installation file of the first application from an application store in the second electronic device.
