Description

Display method and electronic equipment during display mode switching

Technical Field

The present disclosure relates to the field of electronic devices, and in particular, to a display method and an electronic device for switching display modes.

Background

Currently, with the increasing progress of terminal technology and equipment, the styles and kinds of terminals are also continuously enriched. For example, the conventional terminal adopts a flat screen design, and with popularization of various applications, demands for large-screen mobile phones are becoming stronger. But large-screen mobile terminals such as mobile phones have a problem of inconvenient carrying. Accordingly, a folding screen mobile terminal with an extendable and bendable screen is popular with users. For another example, the terminal can implement a plurality of screen displays by expanding the display device.

A switching event of the display mode may occur when the display contents of the terminal are switched from one screen to another screen or when one state of the screen is switched to another state for display. Before and after the display mode is switched, if there is a difference in the parameters of the display area (screen) in which the display content is located, there may be a problem in that the display content is abnormal.

Disclosure of Invention

According to the display method and the electronic device for switching the display modes, the problem that display content is abnormal during switching the display modes can be avoided.

In a first aspect, an embodiment of the present application provides a display method during switching a display mode, which is applied to a terminal, where the terminal includes a screen; the display method comprises the following steps:

Acquiring display mode information of a terminal;

obtaining changing information of display mode configuration information corresponding to a switching event of a display mode when the switching event of the display mode occurs on a screen according to the display mode information;

obtaining state information for representing a screen layout change event according to change information of display mode configuration information under the condition that the type of the switch event of the display mode is a first type;

refreshing a target interface of an application displayed on a screen when it is determined that the state information for representing the screen layout change event indicates that the screen layout information of the screen is changed and the type of the switching event is a first type;

and displaying the refreshed target interface on the screen according to the change information of the display mode configuration information.

In general, when a switching event of a display mode occurs, WMS module of an application Framework layer (Framework) of the terminal acquires change information of configuration information of the display mode, processes the change information of the configuration information of the display mode according to a pre-configured processing flow, and finally further determines or reports the processed change information. Through the steps of the display method, the judgment operation on whether to refresh the target interface is added on the basis of the original processing logic of the application framework layer of the terminal, so that the original processing logic of the application framework layer of the terminal is not required to be adjusted in a large scale, and the application convenience is improved.

When a switching event of a display mode occurs, state information is firstly determined according to changing information of display mode configuration information, whether a target interface is refreshed is determined according to changed data items in the display mode configuration information, so that when the target interface needs to be refreshed, the state information is recorded, when the changing information of the display mode configuration information and the type of the switching event meet the requirements corresponding to the refreshed target interface, the target interface is refreshed, visual perception of a user is prevented from being influenced due to insufficient adaptation degree of the target interface and the display mode after switching when the display mode is switched, and visual effect of the user in use is improved.

In one embodiment, the display method at the time of switching the display modes further includes:

filtering the change information of the display mode configuration information to obtain filtered first information when the state information for representing the screen layout change event indicates that the screen layout of the screen is not changed and the type of the switching event is the second type;

and sending the filtered first information to an application layer, wherein the filtered first information is used for indicating the interface parameters of the target interface displayed by the application modification screen.

The display mode switching event is not equivalent to a screen layout change event. The display mode switching event may cause a plurality of data items in the display mode configuration information to be changed, wherein the data items may include data items corresponding to the screen layout changing event, and if the data items corresponding to the screen layout changing event are not included in the change information of the display mode switching event, the screen layout is indicated not to be changed due to the switching of the display mode.

If the state information representing the screen layout change event indicates that the screen layout is not changed, the display mode before the switch event occurs is the same as the screen layout of the display mode after the switch event occurs, and a new screen layout is not required to be adapted by using a mode of refreshing the target interface. Therefore, when the screen layout is not changed and the type of the switching event is the second type, the target interface can not be refreshed, and the operation of the terminal system is reduced.

filtering the change information of the display mode configuration information to obtain filtered second information;

under the condition that the state information for representing the screen layout changing event indicates that the screen layout of the terminal is changed and the type of the switching event is the first type, generating new changing information of the display mode configuration information according to the filtered second information;

obtaining second changing information of the display mode configuration information according to the changing information of the new display mode configuration information and the screen layout information; and the second change information of the display mode configuration information is used for obtaining the refreshed target interface.

In general, when a switching event of a display mode occurs, change information of display mode configuration information is acquired, then the change information of the display mode configuration information is filtered, data items which need to be focused by an application and refer to a modification target interface are determined, and the application is notified according to the data items which remain after the filtering, so that the application correspondingly modifies the target interface.

In the embodiment of the present application, when the state information for representing the screen layout modification event indicates that the screen layout of the terminal is modified, and the type of the switching event is the first type, it is considered that the difference between the display modes before and after the occurrence of the switching event belongs to the first type, that is, the target interface needs to be refreshed according to the display modes before and after the occurrence of the switching event. And then judging whether the target interface needs to be refreshed according to whether the display mode configuration information contains the appointed screen layout information or not, and further generating second change information for obtaining the refreshed target interface according to the double condition judgment result, so that the application can refresh the target interface according to the second change information.

In one embodiment, refreshing a target interface of an application of a screen display includes:

and sending a target interface refreshing request and second change information of the display mode configuration information to an application layer of the terminal, so that the application generates a refreshed target interface according to the second change information of the display mode configuration information.

The window management service of the terminal sends a refreshing request of the target interface to the application, and the refreshing request is sent and carries the second change information, so that the application of the terminal refreshes the target interface according to the second change information to obtain the target interface matched with the second change information of the display mode configuration information, and the problems that the target interface cannot be filled in a display area of a screen and cannot display all contents in the display area after the display mode is switched due to the fact that the target interface is displayed according to parameters in the display mode before the switching in the display mode after the switching of the target interface are avoided.

In one embodiment, obtaining second change information of the display mode configuration information according to the change information of the new display mode configuration information and the screen layout information includes:

adding the screen layout information into the change information of the new display mode configuration information to obtain second change information of the display mode configuration information.

In general, each application sets a corresponding filtering condition, and when the display mode configuration information changes, obtains change information of the display mode configuration information, and filters the change information according to the filtering condition. The filtering conditions of each application configuration are mainly used for screening the change information which does not need to be focused by the application, so that fewer adjustment operations are performed on the generated target interface as much as possible when a switching event of a display mode occurs in the running process of the application. However, there may be cases where after the display mode switching event occurs in the terminal, if some parameters of the target interface are not changed, a certain display problem may be caused.

In the embodiment of the present application, after the filtering step is performed, whether the obtained second modification information needs to be modified is determined according to the type of the switching event and whether the modification information includes a data item corresponding to the screen layout information, and if it is determined that the modification is needed, the screen layout information is added to the modification information of the new filtered display mode configuration information, so that it is ensured that the screen layout information affecting the display effect can be sent to the application under the condition that the target interface needs to be refreshed, so that the application does not ignore the modification of the screen layout information due to filtering.

In one embodiment, adding screen layout information to the change information of the new display mode configuration information includes:

the screen layout information is connected with the change information of the new display mode configuration information by an OR operation instruction, so that the screen layout information is added into the change information of the new display mode configuration information.

The screen layout information contained in the change information of the display mode configuration information before filtering is connected with the new display mode configuration information obtained after filtering by a OR operation instruction, so that the screen layout information connected by the OR operation instruction is received when the application can configure the new display mode configuration information, and the refreshed target interface is adjusted according to the screen layout information, so that the refreshed target interface is suitable for the display area after the display mode is switched.

in the case where the change information of the display mode configuration information includes screen layout information, determining that the state information for representing the screen layout change event indicates that the screen layout of the terminal is changed;

and obtaining the type of the switching event of the display mode according to the display mode information.

Before determining to refresh the target interface, it is required to determine whether the terminal satisfies two conditions, one is a type of a switching event of the display mode, and the other is whether the screen layout information changes when the switching event of the display mode occurs. And under the condition that the two conditions are met, determining that the request application refreshes the target interface.

In one embodiment, determining status information for a screen layout modification event according to modification information of display mode configuration information includes:

generating a bit zone local variable as state information of a screen layout change event when the screen layout information is included in the change information of the display mode configuration information;

the flag bit local variable is assigned to a first value, and state information representing a screen layout change event indicates that the screen layout of the terminal is changed.

Since the type of the switching event has been determined to be the first type, in the case where it is further determined that the screen layout information is included in the change information of the display mode configuration information, that is, the switching event is determined to be an event requiring attention of the application, and at the same time, the screen layout information is changed, it is determined that the application can be requested to refresh the target interface. Since it is generally necessary to perform a series of processing operations including judgment, filtering, transmission, and the like on the change information of the display mode configuration information in the window management service module of the terminal. In the embodiment of the application, before filtering the change information of the display mode configuration information, the flag bit local variable is generated and used as the indication information of whether to refresh the target interface, so that the normal processing flow of the window management service on the change information of the display mode configuration information is not required to be changed, and the screen layout information and other information loss which has decisive effect on whether to refresh the target interface is avoided because of the filtering and other operations of the window management service module on the change information of the display mode configuration information, thereby being beneficial to accurately judging whether to refresh the target interface.

In one embodiment, obtaining status information representing a screen layout modification event according to modification information of display mode configuration information includes:

in the case where the screen layout information is not included in the change information of the display mode configuration information, the flag bit local variable is assigned to a second value to indicate that the state information for representing the screen layout change event indicates that the screen layout of the terminal has not been changed.

In a specific implementation manner, the flag bit local variable is assigned to the second value by default, which means that the refresh operation on the target interface is not required. Therefore, when the screen layout information is not included in the change information of the display mode configuration information, the local variable of the zone bit is not modified, so that the second value is reserved.

In one embodiment, the screen is a folding screen; the folding screen can be folded to form at least two screens, the at least two screens comprise a first screen and a second screen, and in the unfolded state, the first screen and the second screen are opposite; the screen switch event includes: the target interface is switched from being displayed on the first screen to being displayed on the second screen; displaying the refreshed target interface on a screen, including:

and displaying the refreshed target interface on the second screen.

Under the condition that the screen of the terminal is a folding screen, the positions of the screen displayed by the target interface are different before and after the switching event of the display mode, so that the configuration information of the display mode of the target interface in the terminal is different before and after the switching event of the display mode. The target interface is displayed on a first screen of the folded screen before the switching event occurs, and on a second screen opposite the first screen after the switching event occurs.

In one embodiment, in the case where the change information of the display mode configuration information includes screen layout information, the screen layout information includes screen size gradation information and wide screen indication information before a switching event of the display mode, and screen size gradation information and wide screen indication information after the switching event of the display mode.

When the folding screen switches the display mode in the source code, the values of the screen size, the minimum screen size and the screen layout information in the change information of the display mode configuration information are filtered according to the threshold value of the application configuration. If the screen layout information is filtered out, a part of application interfaces are not adapted to screen cutting after the display mode is switched to obtain a screen, in the embodiment of the application, the scene is judged, then the value of the screen layout information is added back to the change information of the display mode configuration information, and the window management service makes judgment on whether to refresh the target interfaces of the application or not based on the zone bit local variables, so that the adaptation of the application interfaces to the screen before and after the screen cutting is ensured.

judging that the screen switching event is of a first type when the folding screen is converted from an unfolded state to a folded state or when the folding screen is converted from the folded state to the unfolded state;

in the event that the folding screen transitions from the unfolded state to the hovering state, or the folding screen transitions from the folded state to the hovering state, it is determined that a screen switch event is of the first type.

In this embodiment, the type of the screen switching event can be determined according to the characteristics of the terminal having the folding screen, so that it can be accurately determined whether to refresh the target interface when the folding and unfolding states of the folding screen are switched.

filtering the change information of the display mode configuration information under the condition that the type of the switching event of the display mode is the second type, and obtaining filtered third information;

and reporting the filtered third information to an application layer of the terminal, wherein the filtered third information is used for indicating an application to change a target interface displayed on a screen.

When the type of the switching event accords with the condition of refreshing the target interface, but the screen layout information is not included in the change information of the display mode configuration information, the target interface is still considered to be unnecessary to refresh, and the filtered third information is directly reported.

In one embodiment, the change information of the display mode configuration information includes at least one of information, and the change information of each display mode configuration information records a parameter before a switching event of the display mode and a parameter after the switching event of the display mode; filtering change information of display mode configuration information, including:

for the change information of each display mode configuration information, filtering the parameters before the switching event of the display mode and the parameters after the switching event of the display mode when the parameters before the switching event of the display mode and the parameters after the switching event of the display mode are larger than a preset threshold;

for the change information of each display mode configuration information, filtering the parameters before the switching event of the display mode and the parameters after the switching event of the display mode when the parameters before the switching event of the display mode and the parameters after the switching event of the display mode are smaller than a preset threshold.

And carrying out unilateral filtering through a preset threshold value, so that when the change information amplitude of the display mode configuration information is not large enough, the application can ignore the change information, and unnecessary change operation of display parameters of the target interface is reduced as much as possible.

In one embodiment, the change information of the display mode configuration information includes: the screen size change information and the physical screen size change information are available.

In the embodiment of the application, the change information of the display mode configuration information may include a plurality of data items, and different data items are used for representing the changes of different dimensions of the display mode configuration information.

In a second aspect, an embodiment of the present application provides an electronic device, including a processor, where the processor is coupled to the memory, and the processor is configured to execute a computer program or instructions stored in the memory, so that the electronic device implements a display method when a display mode is switched as provided in any one embodiment of the present application.

In a third aspect, embodiments of the present application provide a computer-readable storage medium storing a computer program that, when executed on an electronic device, causes the electronic device to perform a display method at the time of display mode switching as provided in any embodiment of the present application.

It will be appreciated that the advantages of the second to third aspects may be found in the relevant description of the first aspect, and are not described in detail herein.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

It should be understood that reference herein to "a plurality" means two or more. In the description of the present application, "/" means or, unless otherwise indicated, for example, a/B may represent a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, for the purpose of facilitating the clear description of the technical solutions of the present application, the words "first", "second", etc. are used to distinguish between the same item or similar items having substantially the same function and effect. It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ.

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.

Before introducing embodiments of the present application, some terms or concepts related to the embodiments of the present application are first explained. It is to be understood that the nomenclature that follows is not specifically defined. Other designations are possible for the following terms. The renamed terms still satisfy the following related term explanations.

A screen is a device or an electric appliance for displaying images and colors, and may also be called a display screen. The method is widely applied to mobile phones, computers, displays, televisions and equipment with image or text display functions.

In the case where the screen of the mobile terminal includes two or more display areas, the display mode is switched, and the screen is switched from one display area to another. In the case that the mobile terminal is a folding screen, the screen of the mobile terminal may be implemented by being converted from a folded state to an unfolded state or from an unfolded state to a folded state. In the case that the mobile terminal includes one screen, the display mode switching may also be realized by externally connecting other screens and changing the display range of the screen of the mobile terminal.

The display mode, which may also be referred to as a display mode, the terminal may display through a plurality of different display modes. When the display mode is switched, the display mode is switched from one mode to another. For terminals with a folding screen, the display modes may include an extended mode, a folded mode. In addition, the display mode may further include: an extended mode, a mirror mode, a primary screen mode, a secondary screen mode, and the like. The expansion mode is that the terminal is connected with an external screen, and the external screen and the screen of the terminal display the same picture together. In the mirror image mode, the screen of the terminal and the external screen synchronously display the same picture, or at least two screens of the terminal synchronously display the same picture, and two or more screens generate mirror image effects.

The screen layout change event refers to an event of a change in the on-screen display area due to switching of the display mode or other reasons.

Folding screens, i.e. screens that can be bent, are typically flexible screens. In some cases, the folding screen may also be implemented by two or more rigid screens connected by hinges, and in the unfolded state, the two or more rigid screens are spliced into one larger screen. The folding screen may have a folded and unfolded state. In the unfolded state, the folding screen serves as a complete screen, and displays the picture (interface) of the terminal. In the folded state, a certain included angle exists between one part of the folding screen and the other part of the folding screen, and the folding screen and the other part of the folding screen are positioned on different planes.

Fig. 1 is a schematic diagram of a terminal related to a display method during display mode switching according to an embodiment of the present application. As shown in fig. 1, the terminal 11 includes a screen 12, and the screen 12 has two or more display modes. The area on the screen 12 for displaying pictures may be different in different display modes.

For example, in the full-screen display mode, the terminal 11 runs the target screen of the news application, and the screen 12 is used for displaying the first target screen to be displayed, and the first target screen displays the title of the news of the current day and the content abstract of the news in the news application.

In the split-screen display mode, the screen 12 is divided into two areas, each of which displays one target screen of the application, i.e., the first area 13 in fig. 1 displays a first target screen related to the title of the news application, and the second area 14 in fig. 1 displays a second target screen related to the text. When the terminal 11 switches from the full-screen display mode shown in fig. 1 to the split-screen display mode shown in fig. 1, a switching event of the display mode occurs, a dividing line 15 representing the split screen is generated on the screen 12, a first target picture originally displayed in the entire area of the screen 12 is switched to the first area 13, and a second target picture related to the first target picture can be displayed in the second area 14.

Also, in the case where the terminal 11 is shifted from the split display mode to the full-screen display mode, a switching event of the display mode occurs. Therefore, when the terminal 11 is monitored that a switching event of the display mode occurs, the display method for switching the display mode provided by any embodiment of the application can be operated, and the refreshed target interface is displayed on the screen after the display mode is switched.

With the continuous development of electronic equipment technology, more and more terminals with screens are widely used in daily life and work of people, such as mobile phones with screens. And it is not difficult to find that with the development of screen technology, the screen of the terminal becomes larger and larger to provide the user with richer information, and bring better use experience to the user. However, the screen of the terminal is too large, which may seriously affect portability thereof. Therefore, terminals with a folding screen (such as a folding screen mobile phone) proposed in recent years are the direction of development of future electronic devices. Fig. 2 is another schematic diagram of a terminal related to a display method during display mode switching provided in the embodiment of the present application, where the terminal shown in fig. 2 is a mobile terminal with a folding screen. The folding screen may be folded into at least two screens, such as a first screen 21 and a second screen 22 shown in fig. 2 (a), fig. 2 (b), and fig. 2 (c). After the folding screen is fully folded, as shown in fig. 2 (a), the first screen 21 and the second screen 22 are opposed. In general, the aspect ratio (i.e., aspect ratio) of the first screen 21 and the second screen 22 of the folded screen is similar to that of a conventional non-folded screen, such as an aspect ratio of 16:9, 18:9, 20:9, or 16:10, as may be conventional; some applications are designed for non-folding screens, and the interface layout of the application is matched with the non-folding screen. Therefore, after the folding screen is folded, the first screen or the second screen can normally display each application interface.

Referring to (b) of fig. 2, after the folding screen is unfolded, the display area of the folding screen includes at least two screens described above, which are formed by splicing the first screen 21 and the second screen 22. The aspect ratio of the unfolded folded screen may be 1:1 or 16:18, etc. When a user watches a movie or plays a game, the terminal can be fully unfolded in the form shown in (b) of fig. 2, and an immersive use experience is brought to the user. When a user wants to release both hands to use the terminal, the terminal can be folded at a certain angle and placed in a bracket shape, so that the user can use the terminal and process other transactions; for example, a user takes a picture while both hands participate in posing, etc.; the terminal may be in a cradle-type placement configuration as shown in fig. 2 (c).

Folding screens in embodiments of the present application may be divided into a number of different categories, including: a category of folding screens turned outwards (called outwards folding screens for short), and a category of folding screens turned inwards (called inwards folding screens for short). Taking an example that the folding screen can be folded to form a first screen and a second screen, after the outward folding screen is folded, the first screen and the second screen are opposite; after the folded inward folding screen is folded, the first screen is opposite to the second screen, and fig. 2 is a schematic diagram of the folded inward folding screen in the embodiment of the application.

Fig. 3 (a) is a schematic view of the terminal 31 with the folding screen 32 folded out when fully unfolded. The out-turned folding screen 32 can be turned over along the folding edge 35 in the directions 301a and 301b shown in fig. 3 (a), and can form a first screen 33 and a second screen 34 shown in fig. 3 (b). At the position where the planes of the first screen 33 and the second screen 34 intersect, a folded edge 35 is formed. The out-turned folding screen may continue to be turned along the folding edge 35 in the directions 302a and 302b shown in fig. 3 (b), forming the out-turned folding screen 32 in the folded state shown in fig. 3 (c). As shown in fig. 3 (c), the first screen 33 and the second screen 34 are opposite to each other after the out-folding screen 32 of the terminal 31 is completely folded, and are visible to the user.

It will be appreciated that for a terminal 31 having an accordion folding screen 32 as shown in fig. 3, an interface may be displayed on the first screen 33 and/or the second screen 34 when the accordion folding screen 32 is in the folded state; an interface may also be displayed on the first screen 33 and/or the second screen 34 when the out-folded screen 32 is in the unfolded state. The description of the unfolded state and the folded state of the folded screen may refer to or be combined with the description of other embodiments, which are not repeated herein.

Fig. 7A is a schematic application scenario diagram of a display method during display mode switching according to an embodiment of the present application. The terminal 71 has a folding screen 72, which folding screen 72 is a flexible screen that can be folded about a folding line 73 in the direction indicated by the curved arrow. Further, the folding screen 72 includes a first screen 74, a second screen 75, and a third screen. In the unfolded state shown in fig. 7A, the first screen 74 and the second screen 75 are in the same plane, the angle between the first screen 74 and the second screen 75 is close to 0 °, and the third screen is opposite to the first screen 74 or the second screen 75. Correspondingly, the display mode of the terminal 71 is the display mode of the unfolded state. The first screen 74 and the second screen 75 form a complete large screen on which the content to be displayed is displayed. When the user switches the display screen of the terminal 71 to the desktop, the terminal 71 displays the desktop background and application icons 76 of a plurality of applications laid out on the desktop, and the user clicks one of the plurality of application icons 76 by touch to start the application, and displays an interface corresponding to the application on the large screen, as shown in fig. 7B.

In the expanded state shown in fig. 7B, the application-corresponding target interface may occupy the area of the entire large screen.

In another implementation, in the expanded state, as also shown in fig. 7B, the application-corresponding target interface may be displayed in a first region corresponding to the first screen 74, a second region corresponding to the second screen 75. In the first area, a home page, a menu presentation page, a tab page, etc. corresponding to the application may be displayed. And in the second area, the landing page corresponding to the specific option selected by the user in the first area can be displayed.

In the case where the folding screen 72 is an out-folded folding screen, the user folds the folding screen 72 outwardly along the folding line 73 such that the first screen 74 and the second screen 75 are opposed, and the terminal 71 is in a folded state. In the folded state, one of the first screen 74 and the second screen 75 is extinguished, and the other is in the lit state, and in the folded state, the lit first screen 74 or the second screen 75 displays the target interface of the application.

For a scenario in which the folding screen 72 is an inwardly folded screen, the folding screen 72 of the terminal 71 includes a third screen 77, as shown in fig. 7C. The user folds the folding screen 72 inwardly along the fold line such that the first and second screens are opposed (not shown in fig. 7C because of the occlusion) with the terminal 71 in a folded state. In the folded state, both the first screen and the second screen are extinguished, and the third screen 77 is lit and displays the target interface of the application, opposite to the first screen and the second screen.

Referring to fig. 8, an embodiment of the present application provides a display method during switching a display mode, which is applied to a terminal, where the terminal includes a screen; the display method includes steps S801 to S805 as shown in fig. 8.

In step S801, display mode information of a terminal is acquired.

In the embodiment of the application, the terminal includes, but is not limited to, electronic devices such as notebook computers, desktop computers, palm computers, tablet computers, mobile phones, wearable intelligent devices, and the like. The terminal has at least one screen, which may belong to the same display or to different displays. In one embodiment, the screen included in the terminal may be an external screen of the host device of the terminal, or the screen included in the terminal may be a screen of a display fixedly configured by the host device of the terminal.

The terminal is operated with a corresponding system, a certain target interface can be displayed, and the target interface can be started when the application is operated in the system of the terminal. The terminal is correspondingly provided with at least two display modes, and the areas for displaying the target interface are different in different display modes.

In a specific implementation, the terminal may include a first display mode and a second display mode. In the first display mode, the distance between the upper edge and the lower edge of the visual direction of the target interface in the use state of the user is larger than the distance between the left edge and the right edge. In the second display mode, the distance between the upper edge and the lower edge of the visual direction of the target interface in the use state of the user is smaller than the distance between the left edge and the right edge.

In another specific implementation, the terminal may include a third display mode and a fourth display mode. The resolution of the third display mode and the fourth display mode are different, resulting in a target interface covering different areas on the screen of the terminal. For example, in the third display mode, the screen resolution is 2560x1440. In the fourth display mode, the screen resolution is 3840x2160.

In another specific implementation, the terminal may include a fifth display mode and a sixth display mode. In the sixth display mode, one screen of the terminal is used for displaying the target picture, and when the application runs, the target interface of the application covers the whole area of the screen. In the fifth display mode, one screen of the terminal is partially used for displaying the target screen, and the other portion displays at least one of a keyboard, a touch pad operation interface, and a mouse operation interface. And displaying a target interface of the application currently running by the terminal in a first area of the screen, and displaying a black screen in a second area of the screen to show that the second area can be used as a touch pad.

In another specific implementation, the terminal may include a seventh display mode. In the seventh display mode, the screen is divided into a first divided screen and a second divided screen based on the fifth display mode. A split screen line is displayed between the first split screen and the second split screen, and the split screen line divides the display area of the screen so as to divide the screen into the first split screen and the second split screen. In the first split screen and the second split screen, the user can run different applications according to own will, for example, the first split screen runs a shopping application, and a target interface of the shopping application is displayed, wherein the target interface comprises a plurality of commodities and corresponding commodity brief information. And running the social application by the second split screen, and displaying a target interface of the social application, wherein the target interface comprises a plurality of social friends and chat lists corresponding to the social friends.

In another specific implementation, the terminal may include an eighth display mode and a ninth display mode. In the eighth display mode, the terminal uses a screen display target interface fixedly matched with the terminal host. The notebook computer displays a target interface of the desktop through a fixed matched screen. In the eighth display mode, the terminal may display the fixed screen in any one of the first display mode to the seventh display mode. In the ninth display mode, the terminal displays through a screen fixedly matched with the terminal host and an external screen of the terminal. The notebook computer can respectively realize the functions similar to the first split screen and the second split screen in the seventh display mode through the fixed matched screen, the screen externally connected with the display, the target interface of the desktop, the fixed matched screen and the screen externally connected with the display.

In another specific implementation, the screen of the terminal is a flexible screen. The flexible screen includes a first screen, a second screen, and the terminal may include a tenth display mode and an eleventh display mode. In the tenth display mode, the flexible screen is unfolded, the first screen and the second screen are substantially in the same plane, and the angle between the two screens is close to 0 °. The display areas of the first screen and the second screen are spliced to be used as a complete large screen. In the eleventh display mode, the flexible screen is folded outwardly, the first screen and the second screen are opposite, one of the first screen and the second screen is lighted for displaying the target interface, and the other is extinguished.

In another specific implementation manner, the screen of the terminal is a flexible screen, the flexible screen comprises a first screen, a second screen and a third screen, and the terminal may further have a twelfth display mode on the basis of the tenth display mode. In a tenth display mode, the flexible screen is unfolded, the large screen formed by the third screen, the first screen and the second screen is opposite to each other, and the large screen formed by the first screen and the second screen is lightened and used for displaying a target interface. In the twelfth display mode, the first screen and the second screen are folded inwardly and the first screen and the second screen face each other. And the third screen is lightened and used for displaying the target interface.

In other possible implementations, the terminal may also have more display modes, or a combination of two or more of the aforementioned first to twelfth display modes.

In step S802, when it is determined that a switching event of the display mode occurs on the screen based on the display mode information, change information of display mode configuration information corresponding to the switching event of the display mode is obtained.

The switching event of the display mode, which is an event generated when the display mode of the screen is switched from one to another, can be determined by monitoring the mode information displayed by the screen. When a switching event of the display mode occurs, the terminal may have a change of a screen-related hardware device, or may only have a change of a screen-related software parameter.

In order to monitor the screen related hardware device changes, multiple sets of sensors may be provided on the terminal. For example, in the case where the terminal has a folding screen, sensor modules are provided at a first screen and a second screen of the folding screen, respectively.

Illustratively, the folding screen of the terminal includes a first screen and a second screen. Wherein the first screen is provided with an acceleration sensor (ACC) 1 and a GYRO sensor (GYRO) 1, and the second screen of the terminal is provided with an acceleration sensor 2 and a GYRO sensor 2. The terminal can acquire the acceleration of the first screen motion and the angular speed of the first screen rotation by reading the data of ACC 1 and GYRO 1, and further acquire the magnitude and the direction of the gravity acceleration G1 of the first screen. The terminal can acquire the acceleration of the second screen motion and the angular speed of the second screen rotation by reading the data of ACC 2 and GYRO 2, further acquire the magnitude and the direction of the gravity acceleration G2 of the second screen, and detect the switching event of the display mode. The terminal can also acquire parameters such as an included angle alpha between the first screen and the second screen according to G1 and G2. The specific method for acquiring the gravitational acceleration G and the included angle α between the first screen and the second screen by the terminal according to the data of the ACC and the GYRO may refer to the description in the conventional technology, which is not repeated herein. Alternatively, if one sensor a is used to be able to detect the magnitude and direction of the gravitational acceleration G, the sensor a may be provided on the first screen and the second screen, respectively. For example, the acceleration sensor and the gyro sensor may be integrated into one sensor (a+g sensor) provided on the first screen and the second screen, respectively.

The first screen and the second screen of the terminal may be further provided with a plurality of groups of touch devices, so that a grasping gesture of a user when using the terminal may be determined, and a display mode of the terminal may be determined.

In each display mode, display mode configuration information is correspondingly arranged for determining parameters related to various displays in the display mode. By way of example, the display mode configuration information may include display region size, scale, resolution, layout information of the display region, and the like. After the terminal is started, the terminal can determine a display mode according to default display mode configuration information, or determine the display mode according to the state of a screen when the terminal is started, and determine the content of difference of the display mode configuration information, namely the change information of the display mode configuration information, under the condition that the display mode is changed. For example, in the first display mode, the display mode arrangement information includes vertical and horizontal direction information, screen size information, screen number information, and the like, and when the vertical and horizontal direction information is changed in the case of switching from the first display mode to the second display mode, the content corresponding to the vertical and horizontal direction information is regarded as change information of the display mode arrangement information.

In step S803, in the case where the type of the switching event of the display mode is the first type, status information for representing a screen layout change event is obtained according to the change information of the display mode configuration information.

In a specific embodiment, the type of switching event of the display mode indicates the display mode before switching and the display mode after switching. The types of switching events of the display modes may be divided in a defined manner. For example, when the display mode before switching is the tenth display mode and the display mode after switching is the eleventh display mode or the twelfth display mode, the type of the switching event of the display mode may be defined as the first type. For another example, when the display mode before switching is the first display mode and the display mode after switching is the second display mode, the type of the switching event of the display mode may be the second type.

In a specific embodiment, when a switching event of the display mode occurs, the screen layout will change correspondingly, but when certain types of switching events occur, the change of the screen layout is ignored, so that the visual experience of a user for watching the target interface is not affected. The state information is used for representing the screen layout changing event, and is used for representing whether the screen layout changing event needs to cause refreshing of the target interface or not according to the highest priority, if the current switching event occurs, the change of the screen layout is ignored to influence the visual experience of a user for watching the target interface, and then the state information indicates that the refreshing operation needs to be performed on the target interface because the current screen layout changing event occurs, so that abnormal display caused by displaying the target interface in a new display mode according to the display mode configuration information before switching is avoided.

Determining the status information for representing the screen layout modification event may include determining whether to refresh the target interface according to the screen layout modification event such that the target interface is displayed according to the display mode configuration information in the new display mode.

In step S804, in the case where it is determined that the state information indicating the screen layout change event indicates that the screen layout information of the screen is changed, and the type of the switching event is the first type, the target interface of the application of the screen display is refreshed.

For example, in the case where it is determined that the state information for representing the screen layout modification event indicates that the screen layout information of the screen is modified, and the type of the switching event is the first type, it is considered that the refresh operation is required for the target interface according to the screen layout modification event so that the target interface is displayed according to the display mode configuration information in the new display mode. The type of the switching event may be determined according to a display mode before the switching event occurs and a display mode after the switching event occurs. The Display Mode before and after the switching event occurs may be determined according to Display Mode information (Display Mode) of the terminal screen.

In a specific embodiment, refreshing a target interface of an application of a screen display includes: and sending a refreshing request to an application layer from the WMS module of the terminal, so that the application refreshes the target interface according to the change information of the display mode configuration information to obtain a refreshed target interface, and simultaneously, the parameters of the refreshed target interface are adapted to the change information of the display mode configuration information.

In general, when a switching event of a display mode occurs, WMS module of an application Framework layer (Framework) of the terminal acquires change information of configuration information of the display mode, processes the change information of the configuration information of the display mode according to a pre-configured processing flow, and finally further determines or reports the processed change information. Through steps S801 to S804, on the basis of the original processing logic of the application framework layer of the terminal, the judging operation of whether to refresh the target interface is added, so that the original processing logic of the application framework layer of the terminal does not need to be adjusted in a large scale, and the application convenience is improved.

By determining the status information, it is not necessary to separately record whether the screen layout event is changed or not, or the type of the switching event is the first type, the processing operation of data judgment can be reduced.

In step S805, the refreshed target interface is displayed on the screen according to the change information of the display mode configuration information.

In a specific embodiment, displaying the refreshed target interface on the screen according to the change information of the display mode configuration information includes: and displaying the refreshed target interface on the screen after the display mode is switched, wherein the refreshed target interface is regenerated by the application according to the change information of the display mode configuration information, and the screen after the display mode is switched is determined according to the display mode before the switching event and the display mode after the switching event.

In this embodiment, the target interface after refreshing is obtained by adjusting the target interface before refreshing according to the change information of the display mode configuration information.

Thus, in embodiments of the present application, the screen includes at least one screen for displaying the target interface before and after the switching event occurs.

In the embodiment of the application, under the condition that a switching event of a display mode occurs, state information is firstly determined according to the change information of the display mode configuration information, and whether to refresh a target interface is determined according to the changed data item in the display mode configuration information, so that when the target interface needs to be refreshed, the state information is recorded, and under the condition that the change information of the display mode configuration information and the type of the switching event meet the corresponding requirement of refreshing the target interface, the target interface is refreshed, and visual perception of a user is prevented from being influenced due to insufficient adaptation degree of the target interface and the display mode after switching during display mode switching, and visual effect of the user in use is improved.

and reporting the filtered first information to an application layer of the terminal, wherein the filtered first information is used for indicating the interface parameters of the target interface displayed by the application modification screen.

In a specific implementation, whether the screen layout has been changed may be determined by whether screen layout information is included in the display mode configuration information. The screen mode configuration information comprises a plurality of data items, and the change information of the screen mode configuration information comprises the data items changed when the screen mode is switched.

Filtering the change information of the display mode configuration information to obtain filtered first information, which may include, as the first information, filtering the data items of the remaining change information.

In this embodiment, the display mode switching event is not identical to the screen layout modification event. The display mode switching event may cause a plurality of data items in the display mode configuration information to be changed, wherein the data items may include data items corresponding to the screen layout changing event, and if the data items corresponding to the screen layout changing event are not included in the change information of the display mode switching event, the screen layout is indicated not to be changed due to the switching of the display mode.

and sending a target interface refreshing request and second change information of the display mode configuration information to an application of the terminal, so that the application generates a refreshed target interface according to the second change information of the display mode configuration information.

In this embodiment, a refresh request of the target interface is sent to the application, and the refresh request is sent, and meanwhile, the second change information is carried, so that the application of the terminal refreshes the target interface according to the second change information, and obtains the target interface adapted to the second change information of the display mode configuration information, thereby avoiding the problems that the target interface is displayed in the display mode after switching according to the parameters in the display mode before switching, and the target interface cannot be filled in the display area of the screen, and the target interface cannot display all contents in the display area after switching of the display mode.

In general, each application sets a corresponding filtering condition, and when the display mode configuration information changes, obtains change information of the display mode configuration information, and filters the change information according to the filtering condition. The filtering conditions of each application configuration are mainly used for screening the change information which does not need to be focused by the application, so that fewer adjustment operations are performed on the generated target interface as much as possible when a switching event of a display mode occurs in the running process of the application.

However, sometimes, after the display mode switching event occurs in the terminal, if some parameters of the target interface are not changed, a certain display problem may be caused. For example, as shown in fig. 9A, when the terminal is a folding screen, if the display mode is switched from the display mode corresponding to the folding state to the display mode of the unfolding state, the display is performed according to the display mode configuration information corresponding to the folding state, which may cause the target interface of the application to be blocked, and a blocking area 901 may appear. Referring to fig. 9B, if the terminal is switched from the display mode corresponding to the unfolded state to the display mode corresponding to the folded state, the display is performed according to the display mode configuration information corresponding to the unfolded state, which may cause the target interface of the application to fail to completely cover the display area and the blank area 902 to appear.

In the embodiment of the application, the screen layout information contained in the change information of the display mode configuration information before filtering is connected with the new display mode configuration information obtained after filtering by using the OR operation instruction, so that the screen layout information connected by the OR operation instruction is ensured to be received when the application can configure the information in the new display mode, and the refreshed target interface is adjusted according to the screen layout information, so that the refreshed target interface is suitable for the display area after the display mode is switched.

and determining the type of the switching event of the display mode according to the display mode information.

In a specific implementation manner, before determining to refresh the target interface, it needs to determine whether the terminal satisfies two conditions, one is a type of a switching event of the display mode, and the other is whether the screen layout information changes when the switching event of the display mode occurs. And under the condition that the two conditions are met, determining that the request application refreshes the target interface.

In one embodiment, since the type of the switching event has been determined to be the first type, in a case where it is further determined that the screen layout information is included in the change information of the display mode configuration information, that is, the switching event is determined to be an event requiring attention of the application, and the screen layout information is changed, it is determined that the application can be requested to refresh the target interface. Since it is generally necessary to perform a series of processing operations including judgment, filtering, transmission, etc. on the change information of the display mode configuration information in the WMS module of the terminal. In the embodiment of the application, before filtering the change information of the display mode configuration information, the flag bit local variable is generated and used as the indication information of whether to refresh the target interface, so that the normal processing flow of the WMS on the change information of the display mode configuration information is not required to be changed, and the information loss of the screen layout information and the like which has decisive effect on whether to refresh the target interface is avoided because of the operations of the WMS on the change information of the display mode configuration information, and the like, thereby being beneficial to accurately judging whether to refresh the target interface.

In the case that the screen layout information is not included in the change information of the display mode configuration information, it is explained that although the type of the switching event accords with the first type, the screen layout is not changed before and after switching, so that the requirement of adapting the screen layout after switching to the target interface can be met without refreshing the target interface.

And displaying the refreshed target interface on the second screen. The first screen and the second screen in this embodiment do not completely correspond to the first screen and the second screen in the foregoing embodiments, but are named for distinguishing between the different screens.

In the case of a mobile phone comprising a folding screen, the state of the terminal may comprise an unfolded state and a folded state, the folding screen comprising a first screen and a second screen which are foldable. The unfolded state is used for displaying a target interface of the application through a large screen formed by the first screen and the second screen, the folded state is used as a target interface of the small screen display application through the first screen or the second screen, and the width of the small screen is about one half of that of the large screen. The display of the internal split screen is a characteristic of the mobile phone with a folding screen in the unfolded state, and in a large screen, two target interfaces of one application are displayed in a split screen mode, and the split screen proportion is generally one half. And in the unfolding state, two target interfaces of the application are displayed in the form of an internal screen of the application, in the folding state, a single target interface of the application is displayed, and in the display mode switching, the display mode of the target interface is switched. However, when the width of the small screen is different from one half of the width of the large screen, the phenomenon that the width of the target interface of the application is not adapted to the width of the screen before and after the screen mode is switched is taken as an example, and referring to fig. 9A, when the terminal is switched from the folded state to the unfolded state, the target interface of the application is blocked. When the terminal is switched from the unfolded state to the folded state, the target interface of the application may be left white, as shown in fig. 9B.

The reason for this problem is that when the screen is folded, WMS issues configuration change (change information of display mode configuration information), and the change information carries size change information (i.e., a plurality of data items in the foregoing embodiment), and the size change information includes screen size, smallstscreen size, screen layout information.

The screen size represents the change information of the currently available screen size, which value represents the change of the currently available size with respect to the current aspect ratio, which changes when the user switches between landscape mode and portrait mode.

smallstscreensize represents change information of the physical screen size. This value represents a direction-independent change in size, so that it will only change when the actual physical screen size changes (e.g. switches from the display of the terminal itself to an externally connected display).

Modification of the screen layout information may occur when other screens become active.

The screenLayout includes a plurality of sub-data items: screen size class, whether or not to widescreen indication information, screen direction information, whether or not to round corner screen indication information. Wherein, screen size class includes: four possible contents of screen_size_small (SMALL screen layout SIZE), screen_size_normal (NORMAL screen layout SIZE), screen_size_size (LARGE screen layout SIZE), and screen_size_size (oversized screen layout SIZE) correspond to four different SIZEs of preset screen levels. And whether the screen is wider or not is indicated by the information indicating whether the screen is wider or higher than the normal screen. The screen direction information is used to indicate whether the screen is displayed from left to right or from right to left. And whether the screen is round or not indicates information for indicating whether the screen is round or not.

The WMS may decide to refresh the target interface of the application or directly dispatch the change information of the display mode configuration information to the application, so that the application refreshes the interface according to the change information of the display mode configuration information sent by the WMS. However, the application configures screenSize, smallestScreenSize, screenLayout a threshold value for changing in order to receive the change information of the display mode configuration information only when necessary, and causes the WMS to filter a plurality of data items included in the change information of the display mode configuration information, thereby filtering out unnecessary received data items. Before and after the terminal is unfolded and folded, the WMS determines and filters according to the threshold provided by the application, if a change of a certain data item is on the same side of the corresponding threshold, the data item is filtered out in configuration change and is not sent to the application, and then the target interface is not refreshed according to the filtered out data item. If the filtered data items are screen layout information and there is a large screen layout change on the display screen of the terminal before and after the display mode is switched, the phenomenon that the application target interface is not updated before and after the display mode of the terminal is switched may be caused, and then the covering or white-keeping situation shown in fig. 9A and 9B may occur.

In this scheme, when the WMS determines that the current device is a folded screen and is a cut-screen scene, if there is screen size change screen layout information in configuration change, a FLAG bit local variable (FLAG 1) is set to true (i.e., a first value), and if no screen layout information is included, FLAG1 is set to false (i.e., a second value), and then a procedure for filtering the change information of the display mode configuration information is performed. If the folding screen is not satisfied and is a screen-cutting scene, such as multi-window deformation, full-screen suspension window change or full-screen split screen change, directly running a program for filtering the change information; after filtering new change information is calculated. If FLAG1 is true, CONFIG_SCREEN_LAYOUT is added to the calculated change based on filtering. Finally, the WMS judges whether to be a relatrch or directly send the change information of the new display mode configuration information to the application based on the latest change value.

When the folding screen switches display modes in the source code, the screenSize, smallestScreenSize, screenLayout value in configration change is filtered according to the threshold value of the application configuration. If screen is obtained after screen cutting is not adapted to part of application interfaces after display mode switching is caused by filtering out the screen, in the embodiment of the present application, the scene is judged, then the value of the screen layout is added back to the change information of the display mode configuration information, and WMS makes judgment on whether a target interface of a related application is selected based on a flag bit local variable, so that the size of the screen is ensured to be adapted to the application interfaces before and after the screen cutting.

In a specific implementation, the screen layout information may further include more sub-data items as one data item included in the change information of the display mode configuration information. When the filtering operation is performed, a part of the sub data items in the screen layout information may be filtered, and the other part may not be filtered. In this case, if the target interface needs to be refreshed, the screen layout information before filtering is still added to the change information after filtering in an or operation manner.

In one embodiment, the display method for switching the display modes further includes:

determining that a screen switching event is of a first type in the event that the folding screen transitions from an unfolded state to a folded state, or the folding screen transitions from a folded state to an unfolded state;

in the event that the folding screen transitions from the unfolded state to the hovering state, or the folding screen transitions from the folded state to the hovering state, the occurrence of the screen switch event is determined to be of the first type.

Fig. 10 is a signaling interaction diagram, which illustrates a signaling interaction procedure of a display method according to an embodiment of the present application. Including steps S1001-S1013.

In step S1001: the system library of the terminal obtains the display mode information of the terminal.

In step S1002: the WMS determines that a display mode switching event occurs according to the display mode information.

In step S1003: the WMS obtains change information of the display mode configuration information.

In step S1004: the WMS determines the type of the display mode switching event according to the display modes before and after the display mode switching event.

In step S1005: the WMS determines that the type of the display mode switching event is a type of switching between folding and unfolding of the folding screen (i.e., the first type in the foregoing embodiment), and further determines whether the change information of the display mode configuration information includes screen layout information.

In step S1006: WMS generates a flag bit local variable.

In step S1007: when the change information of the display mode configuration information includes screen layout information, the WMS assigns a flag bit local variable to "true".

In step S1008: when the change information of the display mode configuration information does not include the screen layout information, the WMS assigns the flag bit local variable to "false".

In step S1009: the WMS filters the change information of the display mode configuration information.

In step S1010: and the WMS adds screen layout information into the filtered change information according to the value "true" of the flag bit local variable.

In step S1011: and the WMS sends a target interface refreshing request to the application according to the change information of the added screen layout information.

In step S1012: and the WMS reports the filtered change information to an application layer according to the assignment 'false' of the flag bit local variable.

In step S1013: and after receiving the target interface refreshing request, the application program refreshes the target interface according to the change information of the added screen layout information.
