Description

Display method and electronic equipment

Technical Field

The application relates to the technical field of terminals, in particular to a display method and electronic equipment.

Background

With the development of terminal technology, electronic devices are becoming a necessity in people's daily lives. To achieve various purposes such as large screen display and entertainment, a user may use a screen projection method to project an interface of one electronic device (e.g., a mobile phone) onto another electronic device (e.g., a display screen) for display.

In the related art, a screen projection mode between electronic devices mainly adopts a mirror image mode, that is, a desktop on one electronic device is completely projected onto another electronic device. As shown in fig. 1, when using a mirror mode screen throw, the desktop on the electronic device 200 will maximize the centered display on the screen of the display device 100 (i.e., the screen throw receiving device); operations on the electronic device 200 will also be synchronized in response to the display content on the projection display device 100, i.e., both ends, being synchronized in real time. As can be seen from fig. 1, in the mirror mode, the screen projection content cannot fully support the screen of the display device 100, and black non-display areas are left on two sides of the screen of the display device 100, so that the screen projection effect is poor, and the user experience is affected.

In one possible implementation, the method further includes: when the display screen of the first electronic device is switched from the horizontal screen mode to the vertical screen mode, the first electronic device displays (N-E) desktop pages on the second electronic device, E is a positive integer greater than or equal to 0, E is smaller than N, and the value of E is determined by the horizontal size or the vertical size of the display screen in the vertical screen mode. Therefore, when the display screen of the first electronic device is switched horizontally and vertically, the content displayed on the first electronic device is matched with the size of the display screen of the first electronic device, and user experience is improved.

In one possible implementation, e=n-1.

In one possible implementation, M is greater than or equal to 1, and all desktop pages can be switched for display on the first electronic device, where the method further includes: the method comprises the steps that first electronic equipment receives an interface switching instruction for switching desktop pages; when the number X of desktop pages to be switched is greater than or equal to N, the first electronic equipment responds to the acquired interface switching instruction to switch N desktop pages at one time; when the number X of desktop pages to be switched is smaller than N, the first electronic device responds to the acquired interface switching instruction to switch the X desktop pages at one time. Therefore, the situation of a blank interface in the interface switching process on the first electronic equipment is avoided, and user experience is improved.

In one possible implementation, the method further includes: the first electronic equipment receives an interface switching instruction; the method comprises the steps that first electronic equipment obtains touch parameters corresponding to interface switching instructions; based on the touch parameters, the first electronic device determines the target number of desktop pages to be switched for the interface switching and the desktop pages with the target number to be switched. Therefore, the number of the desktop pages to be switched is determined based on the operation of the user, so that the number of the switched desktop pages accords with the wish of the user, and the user experience is improved.

In one possible implementation, the method further includes: the first electronic equipment receives an interface switching instruction sent by the second electronic equipment, wherein the interface switching instruction is sent after the second electronic equipment receives the operation acting on the second electronic equipment; responding to an interface switching instruction, and switching desktop pages by the first electronic equipment; the desktop page currently displayed by the first electronic device after the desktop page is switched is completely different from the desktop page currently displayed by the second electronic device. Therefore, the first electronic equipment and the second electronic equipment can be in linkage switching, and user experience is improved.

In one possible implementation, the method further includes: and responding to the acquired first instruction, switching the display of N desktop pages into the display of (N-k) desktop pages by the first electronic equipment, wherein k is a positive integer, and 0 < k < N.

The symbol "/" herein indicates that the associated object is or is a relationship, e.g., A/B indicates A or B.

The terms "first" and "second" and the like in the description and in the claims are used for distinguishing between different objects and not for describing a particular sequential order of objects. For example, the first response message and the second response message, etc. are used to distinguish between different response messages, and are not used to describe a particular order of response messages.

In the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality of" means two or more, for example, a plurality of processing units means two or more processing units and the like; the plurality of elements means two or more elements and the like.

In order to overcome the drawbacks of the screen projection in the mirror mode, referring to fig. 1, when the mirror mode screen projection is adopted, the desktop of the screen projection of the electronic device 200 can be correspondingly stretched, scaled and cut according to the size of the screen of the display device 100, but the desktop page of the screen projection displayed on the display device 100 is deformed or cannot be completely displayed.

In addition, a screen projection mode of a computer mode is also developed at present. As shown in fig. 2, when the screen is projected in the computer mode, the desktop on the electronic device 200 is converted into a computer desktop-like style to support the screen of the display device 100 (i.e., the screen projection receiving device), and all applications on the electronic device 200 are hidden in the application drawer in the area b1 in the lower left corner of the desktop in the computer mode. After clicking on the application drawer of region b1, the application on the electronic device 200 may be displayed in region b 2. When the computer mode is used for screen projection, the electronic device 200 and the display device 100 are relatively independent and can be used separately. As can be seen in FIG. 2, the screen-casting mode of the computer mode is a direct and vivid way of changing the desktop of the electronic device 200 into a computer desktop. Because the computer is the product of the traditional desktop office environment, the computer desktop is provided with commonly used files and folders; when the electronic device 200 is a mobile terminal (such as a mobile phone), an application (App) icon is placed on the desktop of the electronic device 200, so that when the electronic device 200 uses a computer mode to throw a screen onto the display device 100, the desktop of the screen thrown onto the display device 100 is contrary to the operation logic of the mobile terminal with App as a core. Because the user does not have the concept of 'files' when using the mobile terminal, the large-area blank of the computer mode desktop after screen projection can be caused, and the utilization rate is low; the App of the mobile terminal with which the user is most familiar is hidden in the application drawer at the bottom of the desktop in the computer mode, which makes it difficult for the user to quickly find the App he needs. In addition, a large number of mobile office users are used to screen the mobile terminals on portable displays, the portable displays are mainly light and thin, are convenient to carry, have small size (generally between 7 inches and 15.6 inches), are provided with touch screens, and support touch operation. If the desktop page of the screen of the computer mode is displayed on the portable display, because the graphical user interface (graphic user interface, GUI) paradigm of the desktop page of the screen of the computer mode is used with a keyboard and a mouse, the App icons on the desktop page of the screen are small in area and close in interval, are only suitable for clicking by the mouse and are not suitable for touch by fingers, so that the user experience on the desktop page of the screen can be very poor, and the user experience is seriously affected.

Further, in order to overcome the defects of screen projection in a mirror image mode and a computer mode and improve screen projection experience of a user, the embodiment of the application provides a display method. According to the display method, when the desktop on the electronic device 200 is projected onto the display device 100, the arrangement sequence of the content such as the App icon, the card and the like of the desktop on the electronic device 200 can be maintained on the display device 100, and N desktop pages on the electronic device 200 can be displayed based on the size of the display screen of the display device 100, wherein N is a positive integer greater than or equal to 1. Therefore, the desktop pages of the screen throwing on the display device 100 are consistent with the desktop pages of the electronic device 200, so that the desktop pages of the screen throwing on the display device 100 conform to the use habit of a user on the electronic device 200, the operation of the user is convenient, and the user experience is improved.

It may be appreciated that, in the embodiment of the present application, the display device 100 may obtain the content (such as a desktop, etc.) of the screen of the electronic device 200 through a screen-casting protocol. By way of example, the projection protocol may include one or more of the Miracast protocol, the AirPlay protocol, the digital living network alliance (digital living network alliance, DLNA) protocol, the intel wireless display technology (intel wireless display, wiDi) protocol, the Chromecast protocol, the wireless home digital interface (wireless home digital interface, WDHI) protocol, the cast+ protocol, and the like.

For example, the electronic device 200 may have: the device comprises a processor, a display screen and a communication module.

Next, a detailed description is given of the display method provided in the embodiment of the present application based on what has been described above.

In the display method provided by the embodiment of the present application, when the electronic device 200 throws a screen to the display device 100, the electronic device 200 may send a screen throwing instruction and a source interface on the electronic device 200 to the display device 100, where the source interface may include (n+m) desktop pages, N is a positive integer greater than or equal to 2, and M is greater than or equal to 0. After acquiring the screen-throwing instruction and the source interface sent by the electronic device 200, the display device 100 may simultaneously display N desktop pages on the electronic device 200 on the display screen of the display device 100 in response to the screen-throwing instruction of the electronic device 200. Wherein the content and the layout contained in each desktop page displayed on the display device 100 are the same as the content and the layout contained in the desktop page corresponding to the desktop page on the electronic device 200. For example, the content contained in each desktop page may include application icons and/or service cards, and so forth. By way of example, a desktop page may be understood as an interface of an area made up of content other than resident content in a page displayed by a desktop on electronic device 200.

In one embodiment, at least N desktop pages displayed on the display screen of the display device 100 include desktop pages currently being displayed on the electronic device 200. When N is 1, the desktop page displayed on the display screen of the display device 100 is the desktop page currently being displayed on the electronic device 200 (hereinafter referred to as "1 st desktop page"). When N is greater than or equal to 2, desktop pages displayed on the display screen of the display device 100 are respectively: the 1 st desktop page, the 2 nd desktop page, …, the nth desktop page; the 1 st desktop page is a desktop page currently being displayed on the electronic device 200, the 2 nd desktop page is a desktop page next to the 1 st desktop page, the 3 rd desktop page is a desktop page next to the 2 nd desktop page, and the nth desktop page is a desktop page next to the (N-1) th desktop page. Wherein, the next desktop page of the nth desktop page is the 1 st desktop page. In some embodiments, when N is greater than or equal to 2, the desktop page displayed on the display device 100 may be, in addition to the desktop page currently being displayed on the electronic device 200 and the desktop page subsequent to the desktop page, the desktop page currently being displayed on the electronic device 200 and the desktop page preceding the desktop page. For example, if the nth desktop page displayed on the display device 100 is the desktop page currently being displayed on the electronic device 200, the (N-1) th desktop page may be the last desktop page of the desktop page currently being displayed on the electronic device 200, and the (N-2) th desktop page is the last desktop page of the (N-1) th desktop page. In some embodiments, when N is greater than or equal to 2, the desktop page displayed on the display device 100 may be, in addition to the desktop page currently being displayed on the electronic device 200 and the desktop page subsequent to or preceding the desktop page, the desktop page currently being displayed on the electronic device 200, the desktop page preceding the desktop page, and the desktop page following the desktop page. For example, if the (N-i) -th desktop page displayed on the display device 100 is the desktop page currently being displayed on the electronic device 200, the (N-i-1) -th desktop page may be the last desktop page of the desktop page currently being displayed on the electronic device 200, and the (N-i+1) -th desktop page may be the next desktop page of the desktop page currently being displayed on the electronic device 200.

In another embodiment, the N desktop pages displayed on the display screen of the display device 100 may not include the interface currently being displayed on the electronic device 200. For example: the electronic device 200 displays an interface of a certain application, and then the electronic device 200 may not throw the screen of the interface of the application, but the electronic device 200 may throw the screen of its desktop pages, where the desktop page displayed by the display device 100 is different from the interface currently displayed by the electronic device 200.

In some embodiments, the source interface sent by the electronic device 200 acquired by the display device 100 may further include resident content besides the desktop page, where the resident content does not change along with the desktop page switching on the electronic device 200, that is, the resident content does not disappear on the electronic device 200 due to the desktop page switching. By way of example, the resident content may be, but is not limited to being, a resident application. At this time, the display device 100 may also display the resident content on its display screen, wherein the resident content remains displayed in the current interface of the display device 100 when the desktop page is switched on the display device 100. Illustratively, the composition and/or content, etc. of the resident content displayed on the display device 100 is the same as the composition and/or content, etc. of the resident content displayed on the electronic device 200. By way of example, the resident content displayed on the display device 100 may be displayed at a location of an area other than N desktop pages on the display screen of the display device 100, for example, an area at a middle portion and a lower portion of the display screen of the display device 100.

For example, when there are only 2 desktop pages in the electronic device 200, as shown in fig. 4 (a), the desktop pages corresponding to the number "1" are the desktop pages currently displayed on the electronic device 200, the desktop page corresponding to the number "2" is the next desktop page after the desktop pages currently displayed on the electronic device 200 are switched, and the contents in the regions Z1 and Z2 are the resident contents. Under the source interface of the electronic device 200 shown in fig. 4 (a), after the electronic device 200 projects a screen onto the display device 100, if the display screen of the display device 100 is sized to support 2 desktop pages, the display device 100 may display the interface shown in fig. 4 (B) at this time. The desktop page corresponding to the number "1" in the interface shown in fig. 4 (B) corresponds to the desktop page corresponding to the number "1" in fig. 4 (a), the desktop page corresponding to the number "2" in the interface shown in fig. 4 (B) corresponds to the desktop page corresponding to the number "2" in fig. 4 (a), and the content displayed in the area Z3 in the interface shown in fig. 4 (B) corresponds to the content displayed in the areas Z1 and Z2 in fig. 4 (a). As can be seen by comparing fig. 4 (a) and (B), after the screen is thrown, the content and the typesetting contained in each desktop page displayed on the display device 100 are the same as the content and the typesetting contained in the desktop page corresponding to the desktop page on the electronic device 200, so that the desktop page displayed on the display device 100 can conform to the use habit of the user on the electronic device 200, thereby facilitating the operation of the user on the display device 100 and improving the user experience. In addition, the resident content on the electronic device 200, that is, the content displayed in the region Z3 on the display device 100, may also be displayed on the display device 100 at the same time, so as to better conform to the usage habit of the user on the electronic device 200 after the screen is thrown. In fig. 4 (B), the resident content displayed by the display device 100 is located below the N desktop pages displayed by the resident content and is located in the center of the display area. Of course, in fig. 4 (B), the resident content may be displayed in other areas, for example, in the lower left or lower right of the display area of the display device 100, where the resident content is displayed below the desktop page displayed by the display device 100; in addition, the resident content may also be displayed above the display area of the display device 100, and may be specific according to the actual situation.

For example, when there are 3 desktop pages in the electronic device 200, as shown in fig. 5 (a), the source interface of the electronic device 200 is shown in the figure, where the desktop page corresponding to the number "1" is the desktop page currently displayed on the electronic device 200, the desktop page corresponding to the number "2" is the next desktop page after the desktop page currently displayed on the electronic device 200 is switched, and the desktop page corresponding to the number "3" is the next desktop page after the desktop page corresponding to the number "2" is switched; in fig. 5 (a), one resident content is displayed under each desktop page, and each resident content includes a phone application, a text message application, a browser application, and a camera application. Under the source interface of the electronic device 200 shown in fig. 5 (a), after the electronic device 200 projects a screen onto the display device 100, if the display screen of the display device 100 is sized to support displaying 3 desktop pages, then the display device 100 may display the interface shown in fig. 5 (B). In fig. 5 (B), the location of the resident content displayed by the display device 100 is similar to the location of the resident content in fig. 4 (B), which is described above, and will not be described in detail here.

In some embodiments of the present application, when the display device 100 displays N desktop pages, the content in the N desktop pages may be enlarged according to the size of the display screen of the display device 100, so that the size of the content displayed on the display device 100 matches the size of the display screen of the display device 100. For example, when the display device 100 is a television and the electronic device 200 is a mobile phone, since the size of the display screen of the television is much larger than that of the display screen of the mobile phone, if the display is performed on the television according to the size of the content in each desktop page on the mobile phone after the mobile phone is used for screen casting, the desktop page displayed on the display screen of the television is too small, and a large area of blank exists on the display screen of the television, which results in a problem of low utilization rate. Therefore, in the case of displaying the contents of the desktop pages on the mobile phone, the television can amplify the contents of the N desktop pages according to a certain proportion, so that the size of the contents displayed on the display screen of the television is matched with the size of the display screen of the television, and the visual experience and the operation experience are improved.

In some embodiments of the present application, the value of N may be determined according to the size of the display screen of the display device 100. For example, the correspondence between the value of N and the size of the display screen of the display device 100 may be preset, so that the value of N may be obtained after the size of the display screen of the display device 100 is obtained. For example, when the display screen of the display device 100 has a size between 7 inches and 15.6 inches, the value of N may be 2; when the size of the display screen of the display device 100 is greater than 15.6 inches, the value of N may be 3, etc., and may be specific according to the actual situation, which is not limited herein.

In some embodiments of the present application, when the display device 100 displays N desktop pages, the lateral size of the display screen of the display device 100 is larger when the display screen of the display device 100 is in the landscape mode, so that the N desktop pages displayed by the display device 100 may be sequentially arranged laterally. For example, with continued reference to fig. 4 (B) and fig. 5 (B), the display screen of the current display device 100 is in a landscape mode, so that N desktop pages displayed by the display device 100 at this time may be sequentially arranged in a landscape direction.

When the display screen of the display apparatus 100 is in the portrait mode, the lateral size of the display screen of the display apparatus 100 is small, so that N desktop pages displayed by the display apparatus 100 may be vertically arranged in order at this time. For example, as shown in fig. 6, if the display screen of the display device 100 is in the landscape mode under the interface shown in fig. 6 (a), when the display screen of the display device 100 is switched from the landscape mode to the portrait mode, the display interface on the display device 100 may be switched to the interface shown in fig. 6 (B). In fig. 6 (a) and (B), the resident content displayed by the display device 100 is located below the desktop page displayed by the resident content and is located in the center of the display area.

As one possible implementation, when the display screen of the display device 100 is in portrait mode, the display device 100 may also vertically display a desktop page, which may be the interface currently being displayed on the display screen of the electronic device 200. In addition, when the display screen of the display device 100 is switched from the landscape mode to the portrait mode, the desktop page displayed on the display screen of the display device 100 at this time may be the desktop page in the first order in the landscape mode. For example, as shown in fig. 7, if the display screen of the display device 100 is in the landscape mode under the interface shown in fig. 7 (a), when the display screen of the display device 100 is switched from the landscape mode to the portrait mode, the display interface on the display device 100 may be switched to the interface shown in fig. 7 (B), and one desktop page and one resident content may be included in the interface shown in fig. 7 (B).

As another possible implementation, when the display screen of the display device 100 is in the portrait mode, if the lateral dimension of the display screen of the display device 100 still supports displaying multiple desktop pages, then the display device 100 may still display multiple desktop pages laterally on its display screen. For example, as shown in fig. 8, two desktop pages are displayed on the display screen of the display device 100 at this time, where the number "1" corresponds to one desktop page and the number "2" corresponds to one desktop page. Additionally, with continued reference to FIG. 8, resident content may also be displayed below the desktop page shown in FIG. 8.

In addition, in this case, after the display apparatus 100 displays a plurality of desktop pages laterally on its display screen, if there is still a desktop page that can be displayed at this time, and there is a display space in the vertical direction of the display screen, the display apparatus 100 may also continue to display the remaining desktop pages in the corresponding display spaces. For example, as shown in fig. 9, three desktop pages are displayed on the display screen of the display device 100 at this time, two desktop pages are displayed horizontally in the upper half of the display screen, and one desktop page is displayed in the lower half of the display screen. Of course, when the display screen of the display device 100 is in the landscape mode, such a display manner may be adopted, and the display manner is not limited herein, and may be specifically determined according to practical situations.

In some embodiments of the present application, when the desktop page of the electronic device 200 after the screen is thrown is displayed on the display device 100, in order to make full use of the display space of the display screen of the display device 100, icons of applications recently opened by the user on the display device 100 may also be displayed on the display screen of the display device 100, and/or icons of applications recently opened by the user on the electronic device 200 may be displayed, so that the user can quickly find out the applications recently opened by the user. The area for displaying the icons of the applications recently opened by the user on the display screen of the display device 100 may be according to actual circumstances, and is not limited herein. By way of example, the display device 100 may, but is not limited to, display icons of applications recently opened by a user side-by-side with resident content. For example, as shown in fig. 10, an icon of an application recently opened by the user may be displayed at an area Z4 at the bottom of the display screen of the display device 100 and near the central position, wherein the area Z4 is displayed side by side with resident content displayed on the display device 100.

After the electronic device 200 finishes the screen projection to the display device 100, the user can perform an operation on the display device 100. Such as: switching desktop pages, etc.

In some embodiments of the present application, when the number of desktop pages of the electronic device 200 that can be displayed by the display screen of the display device 100 at one time is not divided by the total number of the number of desktop pages on the electronic device 200 during the process of switching the interface on the display device 100 by the user, if the interface is switched every time, the interface of the number of desktop pages of the electronic device 200 that can be displayed by the display screen of the display device 100 is switched, when the interface is switched to the last desktop page, a blank situation occurs on the display screen of the display device 100. At this time, the value of M may be greater than or equal to 1 among (n+m) desktop pages included in the source interface acquired by the display apparatus 100.

For example, if the number of desktop pages of the electronic device 200 that can be displayed by the display screen of the display device 100 at a time is 2, the total number of desktop pages on the electronic device 200 is 5, and each time the interface is switched, two desktop pages are switched; at this time, as shown in fig. 11 (a), the user slides with the finger F leftward on the display screen of the display device 100, and then the display interface on the display screen of the display device 100 is switched from displaying the "1", "2" desktop pages to displaying the "3", "4" desktop pages, i.e., the interface shown in fig. 11 (B) is displayed. Next, the user slides the finger F again on the display screen of the display device 100 to the left, and then the display interface on the display screen of the display device 100 is switched from displaying the "3", "4" desktop pages to displaying the "5", "empty" desktop pages, i.e., the interface shown in (C) of fig. 11 is displayed. It will be appreciated that the dashed boxes in fig. 11, except "empty", are interfaces to be switched, and they are described herein for convenience of illustration only; the dashed box corresponding to the "empty" word may or may not be actually present (in this case, the area may be a blank area), and may be specific to the actual situation, which is not limited herein.

Further, to avoid the above-described problem of switching the interface on the display device 100, the embodiments of the present application provide a more dynamic solution.

Specifically, when the number X of desktop pages to be switched is greater than or equal to the number Y of desktop pages of the electronic device 200 that can be displayed on the display screen of the display device 100 at a time, when the user switches the interface on the display device 100, at this time, the display device 100 may acquire an interface switching instruction issued by the user, and then, Y desktop pages to be switched may be moved on the display screen of the display device 100, that is, the desktop pages may be switched. When the number X of desktop pages to be switched is smaller than the number Y of desktop pages of the electronic device 200 that can be displayed on the display screen of the display device 100 at a time, when the user switches the interface on the display device 100, at this time, the display device 100 may obtain an interface switching instruction issued by the user, and then, X desktop pages to be switched may be moved on the display screen of the display device 100, that is, the desktop pages are switched. Thereby solving the problem that the blank appears on the display interface existing in the switching interface on the display device 100. In some embodiments, the number Y may be equal to the number N of desktop pages that the display device 100 is capable of displaying simultaneously.

For example, when X is greater than or equal to Y, with continued reference to FIG. 11, in FIG. 11 (A), the display device 100 displays "1", "2" desktop pages, the desktop pages to be switched are "3", "4", and "5" desktop pages, the number of desktop pages to be switched is 3, and the number of desktop pages Y of the electronic device 200 that can be displayed on the display screen of the display device 100 at a time is 2. Since X.gtoreq.Y, at this time, when the user switches the interface with the finger F on the

display device

100, 2 desktop pages can be moved on the display screen of the display device 100, i.e., the interface shown in (B) of FIG. 11 is displayed.

When X < Y, as shown in fig. 12, in (a) of fig. 12, "3", "4" desktop pages are displayed on the display device 100, the desktop pages to be switched to the left are "1", "2" desktop pages, the desktop pages to be switched to the right are "5" desktop pages, at this time, if the user switches the interface to the right, the number X of desktop pages to be switched is 1, and the number Y of desktop pages of the electronic device 200 that can be displayed on the display screen of the display device 100 at a time is 2. Since X < Y, at this time, when the user switches the interface with the finger F on the

display device

100, 1 desktop page can be moved on the display screen of the display device 100, i.e., the interface shown in (B) of fig. 12 is displayed. In contrast to the interface displayed on the display device 100 after switching (B) of fig. 11 to (C) of fig. 11, which is displayed on the display device 100 after switching (a) of fig. 12 to (B) of fig. 12, it can be seen that the blank interface appearing in (C) of fig. 11 does not appear in (B) of fig. 12.

As a possible implementation manner, in addition to solving the problem of the blank interface appearing in the interface switching on the display device 100 in the above manner, when X is smaller than Y, Y desktop pages may still be switched, but after switching, the display position of the switched desktop pages, the spacing and/or the size of different contents included in the desktop pages, and so on may be adaptively adjusted, so that the size of the display screen of the display device 100 matches with the display position of the switched desktop pages.

In some embodiments of the present application, the number Y of desktop pages of the electronic device 200 that can be displayed by the display screen of the display device 100 at a time may be replaced by the number of desktop pages that can be switched by the user setting or the system preset interface for each switching.

As one possible implementation, the number of desktop pages that can be switched per switching of desktop pages may be determined based on a user's sliding parameters on the display screen of the display device 100. At this time, after the display device 100 obtains the interface switch issued by the user, the sliding parameter corresponding to the interface switch instruction may be obtained, and the number of desktop pages to be switched is determined according to the sliding parameter, so as to switch the desktop pages. By way of example, the sliding parameters may include a sliding distance and/or a sliding speed, etc. In some embodiments, the sliding parameter may be referred to as a touch parameter.

Specifically, fig. 13 shows a schematic diagram of steps for determining the number of desktop pages that can be switched per switching interface based on a sliding parameter of a user on a display screen of the display device 100. In fig. 13, the display screen of the display device 100 may be a touch screen, and the sliding parameter is a sliding distance. As shown in fig. 13, the method comprises the following steps:

first, in S1301, the display screen on the display device 100 may acquire an initial position and an end position at which the user performs a sliding operation. When the user performs a sliding operation, the display screen of the display device 100 can acquire the position, that is, the initial position, when the user touches the display screen of the display device 100. When the user finishes the sliding operation, the display screen of the display device 100 can acquire the position when the user finishes the sliding operation, that is, the end position.

Next, in S1302, a sliding distance for the user to perform a sliding operation may be calculated from the initial position and the end position.

Next, in S1303, the sliding distance is compared with a preset sliding distance threshold, and the magnitude between the sliding distance and the preset sliding distance threshold is determined.

Finally, in S1304, when the sliding distance is greater than the sliding distance threshold, it is determined that the number of desktop pages that can be switched every time the desktop pages are switched is m1. In S1305, when the sliding distance is less than or equal to the sliding distance threshold, the number of desktop pages that can be switched every time the desktop pages are switched is determined to be m2. Here, m1 and m2 may be set according to practical situations, and are not limited herein.

It will be appreciated that the sliding distance in fig. 13 may be replaced by other sliding parameters, such as sliding speed, etc.; in addition, the manner of obtaining the sliding parameter may be replaced by other methods, which are not limited herein, and the replaced scheme is still within the protection scope of the present application.

After the electronic device 200 finishes screen projection to the display device 100, a user can not only operate on the display screen of the display device 100 and the display screen of the electronic device 200 respectively, but also bind the display screen of the display device 100 and the display screen of the electronic device 200 so as to form a linkage desktop with the display interfaces on the two display screens, so that more desktop pages on the electronic device 200 can be displayed at one time, the times of switching the desktop pages by the user are reduced, the user can directly access the desktop pages required by the user, and the use efficiency of the two devices in cooperation is improved. The user may bind the display screen of the display device 100 and the display screen of the electronic device 200 through a specific triggering operation. For example, the triggering operation may include: one or more of a collision between the display device 100 and the electronic device 200, a cross-screen pinching operation, a voice control, and the like are controlled. By way of example, the cross-screen kneading operation may be a multi-finger cross-screen kneading operation, e.g., two-finger, three-finger, etc., without limitation.

For example, as shown in fig. 14 (a), the "d1" and "d2" desktop pages are being displayed on the display device 100, and the "1" desktop page is being displayed on the electronic device 200, wherein the next desktop page of the "1" desktop page is the "2" desktop page, and the next desktop page of the "2" desktop page is the "3" desktop page. In the case shown in fig. 14 (a), after the user controls the electronic device 200 to collide with the display device 100, binding between the display device 100 and the electronic device 200 is completed, and the display screens of the two can be linked. After the display device 100 and the electronic device 200 are bound, as shown in fig. 14 (B), the display interfaces on the display screens of the two devices form a linked desktop, and at this time, the display interfaces on the display device 100 may be switched from displaying "d1" and "d2" desktop pages to displaying "2" and "3" desktop pages.

As shown in fig. 15 (a), the "d1" and "d2" desktop pages are being displayed on the display device 100, and the "1" desktop page is being displayed on the electronic device 200, wherein the next desktop page of the "1" desktop page is the "2" desktop page, and the next desktop page of the "2" desktop page is the "3" desktop page. In the case shown in fig. 15 (a), the user touches the display screen of the display device 100 with one finger of the hand F and touches the display screen of the electronic device 200 with the other finger of the hand F, and performs a finger pinching operation, after which binding between the display device 100 and the electronic device 200 is completed, and the display screens of the two can be linked. After the display device 100 and the electronic device 200 are bound, as shown in fig. 15 (B), the display interfaces on the display screens of the two devices form a linked desktop, and at this time, the display interfaces on the display device 100 may be switched from displaying "d1" and "d2" desktop pages to displaying "2" and "3" desktop pages.

After the display interface on the display screen of the display device 100 and the display interface on the display screen of the electronic device 200 form a linkage desktop, when the user switches the interface on the display device 100 or the electronic device 200, the display interfaces on the display screen of the display device 100 and the display interface on the display screen of the electronic device 200 will be switched in a linkage way. In other words, when the user switches the interface on the display device 100, the interface on the electronic device 200 also follows the switch at the same time; when the user switches the interface on the electronic device 200, the interface on the display device 100 also follows the switching at the same time, so as to achieve the linkage switching effect, facilitate the user to control, and promote the display effect and the user experience. For example, after the electronic device 200 obtains the interface switching instruction issued by the user, the electronic device 2090 may send the interface switching instruction to the display device 100, so that both may perform interface switching at the same time; thereafter, the display apparatus 100 may switch the desktop page in response to the interface switching instruction. Wherein after the display device 100 and the electronic device 200 switch desktop pages, the desktop pages displayed by the two are different.

For example, as shown in fig. 16 (a), the display interface on the display screen of the display device 100 and the display interface on the display screen of the electronic device 200 form a linked desktop. The display screen of the electronic device 200 displays a "1" desktop page, the display screen of the display device 100 displays a "2" desktop page, and the desktop pages to be switched are "4" and "5" desktop pages. In fig. 16 (a), the user slides left on the display screen of the electronic device 200 with the hand F, and thereafter, a desktop page switching occurs. Since the display screen on the electronic device 200 can only display one desktop page at a time, when the user operates to switch desktop pages on the display screen of the electronic device 200, the display screen of the electronic device 200 can switch desktop pages one at a time. As shown in fig. 16 (B), after the desktop page is switched, a "2" desktop page may be displayed on the display screen of the electronic device 200, and a "3" and a "4" desktop page may be displayed on the display screen of the display device 100.

As shown in fig. 17 (a), the display interface on the display screen of the display device 100 and the display interface on the display screen of the electronic device 200 constitute a linked desktop. The display screen of the electronic device 200 displays a "1" desktop page, the display screen of the display device 100 displays a "2" desktop page, and the desktop pages to be switched are "4" and "5" desktop pages. In fig. 17 (a), the user slides left on the display screen of the display device 100 with the hand F, and thereafter, desktop page switching occurs. Since the display screen on the display device 100 can display two desktop pages at a time, when the user operates to switch desktop pages on the display screen of the display device 100, the display screen of the display device 100 can switch two desktop pages at a time. As shown in fig. 17 (B), after the desktop page is switched, a "3" desktop page may be displayed on the display screen of the electronic device 200, and a "4" and a "5" desktop page may be displayed on the display screen of the display device 100.

It will be appreciated that in fig. 16 and 17, when the desktop pages are switched, the number of desktop pages that are switched at a time may be the switching rule described above, and will not be described in detail herein.

Further, after the desktop page displayed on the display screen of the display device 100 and the desktop page displayed on the display screen of the electronic device 200 form a linked desktop, because there is a situation that the user moves the display device 100 or the electronic device 200, when the user moves the display device 100 or the electronic device 200, the positional relationship between the two changes, and at this time, the arrangement order of the desktop pages in the linked desktop formed by the two changes, so that the arrangement order of the desktop pages in the linked desktop at this time does not conform to the use habit of the user. Therefore, after the user moves the display device 100 or the electronic device 200, the display device 100 and/or the electronic device 200 may adjust the combination form of the desktop pages in the linked desktop according to the relative positional relationship between the two, so that the combination form of the desktop pages in the linked desktop accords with the use habit of the user, and further the user experience is improved.

For example, as shown in fig. 18 (a), the displayed desktop page on the display screen of the display device 100 and the displayed desktop page on the display screen of the electronic device 200 constitute a linked desktop. The display screen of the electronic device 200 displays a "1" desktop page, and the display screen of the display device 100 displays a "2" desktop page. In fig. 18 (a), the user can move the electronic device 200 from the left side to the right side of the display device 100. Thereafter, as shown in fig. 18 (B), the electronic apparatus 200 senses a change in its relative position to the display apparatus 100 and moves to the other side of the display apparatus 100. Meanwhile, displayed on the display screen of the display device 100 are "2", "3" desktop pages. Thus, at this point, the desktop page displayed on the display screen of the electronic device 200 may be switched from the last desktop page displayed on the display screen of the display device 100 to the next desktop page of the desktop page, i.e., from the "1" desktop page to the "4" desktop page. It can be understood that, when the user moves the display device 100, the display device 100 and/or the electronic device 200 can adjust the combination of desktop pages in the linked desktop according to the relative positional relationship between the two, and the adjustment manner is the same as the adjustment manner when the user moves the electronic device 200, which will not be described in detail herein.

In some embodiments of the present application, after displaying N (n+.2) desktop pages on the display screen of the display device 100, the user may switch between N desktop pages and (N-k) desktop pages on the display screen of the display device 100 to meet the needs of the user in different scenarios; wherein k is a positive integer, and 0 < k < N.

For example, as shown in fig. 19 (a), two desktop pages are displayed on the display screen of the display device 100. Wherein, applications 1 to 20 in (a) of fig. 19, and applications a to D may constitute one desktop page; applications 21 through 40, and applications a through D may constitute a desktop page. In fig. 19 (a), the display apparatus 100 may display application 1 to application 20 and desktop pages that application a to application D may compose, i.e., the interface shown in fig. 19 (B), on its display screen in response to a switching operation issued by the user to switch 2 desktop pages to 1 desktop page.

It can be understood that, after the user switches N desktop pages to (N-K) desktop pages, the display device 100 may adaptively adjust the intervals between the contents contained in the (N-K) desktop pages, so that the contents contained in the switched desktop pages are maximally distributed over the display screen of the display device 100, avoiding a large-area blank on the display screen of the display device 100, and improving the display effect. For example, with continued reference to fig. 19, after switching the two desktop pages in fig. 19 (a) to one desktop page in fig. 19 (B), the interval between the applications 1 to 20 may be adjusted in fig. 19 (B), so that the applications 1 to 20 may maximize the display screen of the display device 100.

It can be understood that, for the desktop page to be displayed after the switching, the desktop page may be displayed based on a preset switching rule, which may be specific to the actual situation, and is not limited herein. For example, the preset switching rule may be: after switching the N desktop pages to (N-K) desktop pages, the front (N-K) desktop pages among the N desktop pages or the rear (N-K) desktop pages among the N desktop pages are displayed on the display screen of the display device 100; after switching the (N-K) desktop pages to the N desktop pages, K desktop pages before the first desktop page of the (N-K) desktop pages are displayed on the display screen of the display device 100, or K desktop pages after the last desktop page (i.e., the (N-K) th desktop page) of the (N-K) desktop pages are displayed.

In some embodiments of the present application, when switching desktop pages on the display screen of the display device 100, the user may switch by issuing an operation instruction, for example, switching by a voice instruction, switching by a manual operation, or the like. By way of example, a user may reduce the number of desktop pages displayed on the display screen of the display device 100 by zooming in on a particular desktop page on the display screen of the display device 100; in addition, the user may also increase the number of desktop pages displayed on the display screen of the display device 100 by zooming out a particular desktop page on the display screen of the display device 100.

In one example, when the user selects to reduce the number of desktop pages displayed on the display screen of the display device 100, at least the desktop page selected to be enlarged by the user may be included in the switched desktop pages displayed on the display screen of the display device 100. By way of example, only the enlarged desktop page selected by the user may be displayed on the display screen of the display device 100.

For example, as shown in fig. 20 (a), displayed on the display screen of the display apparatus 100 are "1", "2" desktop pages, and the desktop pages to be switched are "3", "4" desktop pages. In fig. 20 (a), on the display screen of the display device 100, the user can enlarge the "2" desktop page by a finger, and in the process of enlarging the "2" desktop page by the user, the "2" desktop page can "push" the "1" desktop page out of the display screen of the display device 100, at which time the interface shown in fig. 20 (B) is displayed on the display screen of the display device 100. In fig. 20 (B), the desktop pages to be switched are "1", "3", "4" desktop pages.

As shown in fig. 21 (a), displayed on the display screen of the display device 100 are "1", "2" desktop pages, and the desktop pages to be switched are "3", "4" desktop pages. In fig. 21 (a), on the display screen of the display device 100, the user can enlarge the "1" desktop page by a finger, and in the process of enlarging the "1" desktop page by the user, the "1" desktop page can "push" the "2" desktop page out of the display screen of the display device 100, at which time the interface shown in fig. 21 (B) is displayed on the display screen of the display device 100. In fig. 21 (B), the desktop pages to be switched are "2", "3", "4" desktop pages.

It will be appreciated that in fig. 20 and 21, the speed at which one desktop page "squeezes" the other desktop page out of the display screen of the display device 100 may be consistent with the speed at which a user zooms in on one desktop page, thereby enhancing the dynamic display effect. In addition, in the process of amplifying one desktop page by the user, other desktop pages displayed on the display screen of the electronic device 100 may be synchronously amplified, so as to enhance the dynamic display effect and improve the user experience.

In addition, when the user switches desktop pages on the display device 100, during the process that the first desktop page "extrudes" the second desktop page out of the display screen of the display device 100, when the amplitude of the first desktop page enlarged by the user is greater than or equal to the preset amplitude value, if the user stops enlarging the first desktop page and/or the user is not manipulating the display device 100 at this time, the display device 100 may directly display the first desktop page on the display screen thereof, but not display the second desktop page. When the magnitude of the first desktop page enlarged by the user is smaller than the preset magnitude value, if the user stops enlarging the first desktop page and/or the user is not manipulating the display device 100 at this time, the display device 100 may be restored to the state before the first desktop page is enlarged by the user again on the display screen thereof, that is, the first desktop page and the second desktop page are displayed simultaneously.

For example, as shown in fig. 22, the "1", "2" desktop pages are displayed on the display screen of the display device 100 in fig. 22 (a), at which time the user enlarges the "2" desktop page with a finger. In the process of the user enlarging the "2" desktop page, the "1" desktop page is simultaneously enlarged and gradually "squeezed out" of the display screen of the display device 100, and the display effect as shown in (B) of fig. 22 is achieved. In fig. 22 (B), the user stops enlarging the "2" desktop page, and at this time, the user enlarges the amplitude of the "2" desktop page by more than the preset amplitude value. Thereafter, the user's finger leaves the display screen of the display device 100, at which time the "2" desktop page may be displayed on the display screen of the display device 100, and the "1" desktop page is not displayed, i.e., the interface shown in fig. 22 (C) is displayed.

As shown in fig. 23, on the display screen of the display device 100 in fig. 23 (a), the "1", "2" desktop pages are displayed, at which time the user enlarges the "2" desktop page with a finger. In the process of the user enlarging the "2" desktop page, the "1" desktop page is simultaneously enlarged and gradually "squeezed out" of the display screen of the display device 100, and the display effect as shown in (B) of fig. 23 is achieved. In fig. 23 (B), the user stops enlarging the "2" desktop page, and at this time, the user enlarges the amplitude of the "2" desktop page to be smaller than the preset amplitude value. Thereafter, the user's finger leaves the display screen of the display device 100, at which time the display screen of the display device 100 may be restored to simultaneously display the "1", "2" desktop pages, i.e., the interface shown in fig. 23 (C).

In one example, when a user selects to increase the number of desktop pages displayed on the display screen of the display device 100 by zooming out a certain desktop page on the display screen of the display device 100, the user may select, through a specific operation, whether to increase the first j desktop pages of the first desktop page being displayed on the display device 100 or to increase the last j desktop pages of the last desktop page being displayed on the display device 100, where j is a positive integer greater than or equal to 1. The value of j may be a fixed value or a dynamically variable value, which is not limited herein. It will be appreciated that when the display device 100 receives a user operation, the display device 100 may add a corresponding desktop page in response to the user operation. Illustratively, the user may increase a desktop page in a direction opposite a side of the display screen of the display device 100 by zooming out on that side. For example, when the side is the side on which the first desktop page being displayed on the display screen of the display device 100 is located, then the last j desktop pages of the last desktop page being displayed on the display screen of the display device 100 are added; when the side is the side on which the last desktop page being displayed on the display screen of the display device 100 is located, then the first j desktop pages of the first desktop page being displayed on the display screen of the display device 100 are added.

For example, as shown in fig. 24 (a), displayed on the display screen of the display apparatus 100 is a "2" desktop page, and the desktop pages to be switched are "1", "3", "4" desktop pages. In fig. 24 (a), on the display screen of the display device 100, the user may zoom out the "2" desktop page on the right side of the display screen of the display device 100 by a finger, and during the zooming out of the "2" desktop page by the user, the "1" desktop page may be gradually displayed on the display screen of the display device 100. In fig. 24 (a), after the finger of the user leaves the display screen of the display device 100, the interface shown in fig. 24 (B) is displayed on the display screen of the display device 100. In fig. 24 (B), the desktop pages to be switched are "3", "4" desktop pages.

As shown in fig. 25 (a), displayed on the display screen of the display device 100 is a "2" desktop page, and the desktop pages to be switched are "1", "3", "4" desktop pages. In fig. 25 (a), on the display screen of the display device 100, the user may zoom out the "2" desktop page on the left side of the display screen of the display device 100 by a finger, and during the zooming out of the "2" desktop page by the user, the "3" desktop page may be gradually displayed on the display screen of the display device 100. In fig. 25 (a), after the finger of the user leaves the display screen of the display device 100, the interface shown in fig. 25 (B) is displayed on the display screen of the display device 100. In fig. 25 (B), the desktop pages to be switched are "1", "4" desktop pages.

It will be appreciated that in fig. 24 and 25, the speed at which one desktop page gradually enters the display screen of the display device 100 under the driving of the other desktop page may be consistent with the speed at which the user zooms out on the other desktop page, thereby improving the dynamic display effect. Of course, when the user operates to increase the number of desktop pages displayed on the display screen of the display device 100, the desktop pages to be increased may be displayed entirely on the display screen of the display device 100 directly, in addition to being gradually displayed on the display screen of the display device 100, when the user is not manipulating the display device 100. For example, during a user's zooming out of one desktop page, the desktop page to be added is not displayed, but rather, when the user is not manipulating the display device 100 (e.g., the user's finger is off the display screen of the display device 100), the desktop page to be added is displayed directly on the display screen of the display device 100.

In addition, when the user selects to reduce a certain desktop page on the display screen of the display device 100 to increase the number of desktop pages displayed on the display screen of the display device 100, when the magnitude of the user reducing the certain desktop page is greater than or equal to the preset magnitude value, if the user stops reducing the desktop page and/or the user is not manipulating the display device 100 at this time, the display device 100 may directly increase the number of desktop pages displayed on the display screen of the display device 100 on the display screen thereof. When the magnitude of the user shrinking a certain desktop page is smaller than the preset magnitude value, if the user stops shrinking the desktop page and/or the user is not manipulating the display device 100 at this time, the display device 100 may be restored to the state before the user shrinks the first desktop page again on the display screen thereof. It will be appreciated that the process of reducing the number of desktop pages to increase the number of desktop pages is opposite to the process of enlarging the number of desktop pages to decrease the number of desktop pages in fig. 22 and 23 above, and will not be described in detail.
