[0063] The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0064] In the existing implementation scheme, as shown in Figure 1A If the user wants to obtain a better immersive experience through full-screen, the operating system in the electronic device switches the application interface from portrait display to landscape display, and the user rotates the electronic device to achieve the immersive experience of full-screen. However, with the development of split-screen technology and the emergence of folding screens, this way of full-screen display of the application interface cannot fully adapt to the various emerging scenarios that require full-screen display.

[0065] For example, with the emergence of folding screens, the display screen of the electronic device is no longer a single rectangular screen, but a screen similar to a square, which can also be called a square screen. As shown in Figure 1BAs shown, when the user wants to click the button to enter the immersive experience of full screen of the video or game, the screen is rotated, and the user rotates the electronic device to watch. However, unlike the ordinary rectangular screen electronic device, because of the particularity of the square screen, whether the screen is rotated or not, the original video or game screen visible interval does not obviously increase, and the user will find that rotating the screen and the electronic device is a redundant and "difficult" operation.

[0066] Therefore, an embodiment of the present application provides a full screen display method, device and electronic device, which can provide a better application interface full screen display mode for the user in various scenarios, and provide the user with convenient, friendly and consistent full screen display experience.

[0067] Hereinafter, first, the terms appearing in the embodiments of the present application are exemplarily described.

[0068] For the electronic device with a folding screen, the screen when the display screen is in an unfolded state is referred to as a complete screen in the embodiments of the present application, and each independent screen constituting the complete screen is referred to as a sub-screen of the display screen. The electronic device based on the folding mode of the display screen can include three states of an unfolded state, an incomplete folding state, and a complete folding state. For example, Figure 2A As shown, the display screen of the electronic device includes two sub-screens, sub-screen 1 and sub-screen 2 located on both sides of the dashed line, when the electronic device is in Figure 2A As shown in part 21 of FIG. 21, the two sub-screens constitute a complete screen when the electronic device is in an unfolded state; Figure 2A As shown in part 22 of FIG. 22, the electronic device is in an incomplete folding state, Figure 2A As shown in part 23 of FIG. 23, the electronic device is in a complete folding state. The incomplete folding state and the complete folding state can be collectively referred to as a folding state.

[0069] The application interface in the embodiments of the present application is a medium interface for interaction and information exchange between the application and the user, which realizes the conversion between the internal form of information and the form acceptable by the user. The common form of the application interface is a graphic user interface (graphic user interface, hereinafter referred to as GUI), which refers to a user interface related to computer operation displayed in a graphical manner. The application interface can be composed of visible interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets.

[0070] The window displaying the application interface in the embodiments of the present application can be considered as the area of the display screen of the electronic device displaying the application interface.

[0071] For the electronic device with the display screen not being a foldable screen: in the case of no split-screen, the window displaying the application interface can be the entire display area of the display screen; in the case of split-screen, the window displaying the application interface can be a partial display area of the display screen.

[0072] For the electronic device with the display screen being a foldable screen, in the case of no split-screen, the window displaying the application interface can be the entire display area of the complete screen or the entire display area of the sub-screen; in the case of split-screen, the window displaying the application interface can be a partial display area of the complete screen or a partial display area of the sub-screen.

[0073] The split-screen in the embodiments of the present application refers to dividing the display area of the display screen into at least two sub-areas, each of which can display the application interface as a window, and the size of the sub-area can be adjusted, and different sub-areas can display the same or different application interfaces, such as Figure 2B As shown, the display area on the display screen of the electronic device is divided into two sub-areas from the part shown by the dashed line, and each sub-area displays the same application interface as a window. For the electronic device with the display screen being a foldable screen, the display area to be split-screened can be the complete screen or a sub-screen, and details can be referred to the above description and the examples about the split-screen of the complete screen and the split-screen of the sub-screen, which will not be described here. Figure 2B

[0074] The aspect ratio of the window in the embodiments of the present application refers to the height of the window / the width of the window. However, the height and the width of the window are related to the specific setting rules. For example, in a possible implementation, the height and the width of the window can be related to the display direction of the application interface. For example, in the two figures of Figure 2C , the window displaying the application interface is the entire display area of the display screen, but, Figure 2C , the height and the width of the window displaying the application interface in the left figure are just opposite to the height and the width of the window displaying the application interface in the right figure, and the aspect ratios of the two windows are reciprocal, and in the subsequent embodiments of the full-screen display method of the present application, the aspect ratio of the window obtained by using this height and width setting rule is taken as an example for description; in another possible implementation, the height and the width of the window can not be related to the display direction of the application interface, so that the aspect ratio of the same window remains unchanged, for example, Figure 2C , no matter whether the display direction of the application interface is shown in the left figure or the right figure, the aspect ratio of the window is always set to Figure 2C , the height and the width shown in the left figure.

[0075] ​The aspect ratio of the graph in the embodiment of the present application in the preset interval includes a square, and a graph similar to a square in shape. The setting principle of the preset interval is that the window with the aspect ratio in the preset interval has a small difference in the user's viewing experience when the application interface is displayed in a horizontal full screen and a vertical full screen. Optionally, the preset interval can be an interval containing 1, and the upper and lower boundaries of the preset interval are close to 1, for example, the preset interval can be [6 / 8, 8 / 6], that is, [0.75, 4 / 3]. The upper and lower boundaries of the preset interval can also be open intervals. Figure 2D The solid line part in FIG. 24 shows an example of a graph similar to a square in shape. For the graph 24, the aspect ratio of the graph is 7:6, and the four corners are arc-shaped; for the graph 25, the aspect ratio of the graph is 6:6 or 6:5; for the graph 26, the aspect ratio of the graph is 7:6, but one corner is missing; for the graph 27, the aspect ratio of the graph is 7:6, but the shape of one side is missing. Figure 2D The graph examples shown are only examples and do not limit the graph similar to a square in shape in the present application. Those skilled in the art can foresee more graphs similar to a square in shape, for example, the aspect ratio close to 1 can be different in each example, the number of arc-shaped corners of the graph 24 can be different, the number of missing corners or sides of the graph 26 and the graph 27 can be different, the missing shape can be changed, and the like, which will not be described here.

[0076] The full screen display method of the embodiment of the present application is exemplarily described below.

[0077] Figure 3A The flow chart of one embodiment of the full screen display method of the present application is shown in FIG. 24, which can include the following steps. Figure 3A

[0078] Step 301: When the instruction for full screen display of the application interface is detected, it is judged whether the window displaying the application interface is a graph with an aspect ratio in a preset interval; the preset interval is an interval containing 1; if the window is a graph with an aspect ratio in the preset interval, step 302 is executed, and if the window is a graph with an aspect ratio not in the preset interval, step 303 is executed.

[0079] The scenarios in which the instruction for full screen display of the application interface is detected include but are not limited to the following scenarios.

[0080] ​The full-screen instruction for the application interface is acquired, for example, the user issues the full-screen instruction to the application by clicking a full-screen button on the application interface, or performing a preset gesture operation on the application interface, or the application triggers a full-screen instruction carried by itself in the running process; for example, for the playing of multimedia files such as videos and pictures, the user can generally issue the instruction for full-screen playing of the multimedia file by clicking the full-screen button (see Figure 3B or rotating the electronic device (see Figure 3C ). For a mobile game, the start item of the game generally includes a full-screen instruction for the game interface, so that the application, that is, the mobile game, can acquire the full-screen instruction from the start item when starting.

[0081] The application interface has been full-screen displayed, but it is detected that the window for full-screen displaying the application interface changes, and the application interface needs to be continuously full-screen displayed in the changed window. The change of the window can include, but is not limited to, the change of the open / close state of the display screen, the split-screen display of the display screen, and the like, so that the window for displaying the application interface changes in direction, shape, size, and the like.

[0082] Step 302: full-screen display the application interface in the window according to the current display direction of the application interface, and the branch process ends.

[0083] The current display direction of the application interface refers to the display direction of the application interface when the instruction for full-screen displaying the application interface is detected.

[0084] Step 303: full-screen display the application interface in the window according to the display direction specified by the application, and the branch process ends.

[0085] The method shown in FIG. 3 full-screen displays the application interface according to the current display direction of the application interface when the window for displaying the application interface is a figure with a preset interval of the aspect ratio, without the rotation of the electronic device by the user. In the scenario where the window for displaying the application interface is a figure with a preset interval of the aspect ratio, the method provides a better full-screen display mode for the user and improves the full-screen experience of the user.

[0086] Based on the embodiment shown in Figure 3A , the full-screen display method of the multimedia file is explained, referring to Figure 3D the upper left figure and the upper right figure, a multimedia file is not full-screen displayed on the application interface of the electronic device, Figure 3DTaking a multimedia file as an example (video), if a user clicks the full-screen button while watching a multimedia file, the electronic device detects the full-screen instruction for the multimedia file (that is, detects the instruction to display the application interface in full screen) and determines whether the window displaying the application interface is a graphic with an aspect ratio within a preset range.

[0087] If the result indicates that the window is a graphic with an aspect ratio within the preset range, as shown in the lower right image, there is no need to rotate the multimedia file. Figure 3D The orientation of the video file (in the center) will be adjusted according to the current display orientation of the application interface to display the multimedia file in full-screen mode within the window. Figure 3D (The middle part is a video).

[0088] If the result indicates that the window is a graphic whose aspect ratio is not within the preset range, then, as shown in the lower left figure, the multimedia file will be displayed in full screen in the window after rotating the application interface according to the display orientation specified by the application.

[0089] based on Figure 3A The illustrated embodiment describes a method for displaying a game in full screen. See also... Figure 3E As shown in the upper left and upper right images, when a user clicks the icon of a game application to launch the game, the application obtains the full-screen instruction for the game interface from the launch items. Correspondingly, the electronic device detects the full-screen instruction for the application interface (that is, detects the instruction to display the application interface in full screen) and determines whether the window displaying the application interface is a graphic with an aspect ratio within a preset range.

[0090] If the result is that the window is a graphic with an aspect ratio within the preset range, then, as shown in the lower right figure, there is no need to rotate the orientation of the game interface. The game interface will be displayed in full screen in the window according to the current display orientation of the game interface.

[0091] If the result indicates that the window is a graphic whose aspect ratio is not within the preset range, then, as shown in the lower left figure, the game interface will be rotated to the correct orientation according to the display orientation specified by the game program and displayed in full screen.

[0092] Figure 4A This is a flowchart of another embodiment of the full-screen display method of this application. Figure 4A The document provides one possible implementation for determining whether a window displaying the application interface is a graphic with an aspect ratio within a preset range. For example... Figure 4A As shown, the method may include:

[0093] Step 401: When an instruction to display the application interface in full screen is detected, obtain the aspect ratio of the window displaying the application interface.

[0094] In practical applications, the height and width values ​​of the window can be obtained separately, and the aspect ratio of the window can be calculated by the height / width ratio; or, if the aspect ratio parameter of the window is set in advance, the aspect ratio of the window can be obtained by obtaining that parameter.

[0095] Step 402: Determine whether the aspect ratio is within the preset range. If it is within the preset range, proceed to step 403; if it is not within the preset range, proceed to step 404.

[0096] The setting of the preset interval can be referred to the relevant description above, and will not be repeated here.

[0097] Step 403: Display the application interface in full screen in the window according to the current display orientation of the application interface, and this branch of the process ends.

[0098] Step 404: Display the application interface in full screen in the window according to the display orientation specified by the application. This branch of the process ends.

[0099] Figure 4A The method shown determines whether a window is a graphic with an aspect ratio within a preset range based on the window's aspect ratio. This is unrelated to the various states of the display screen in the electronic device. For example, the display screen can be a foldable screen or a non-foldable screen. If the display screen is a foldable screen, it can be in a folded state, an unfolded state, or a state that changes between folded and unfolded states. The display screen can be in a split-screen display state or a non-split-screen display state, and so on.

[0100] Figure 4A The method shown determines whether a window is a graphic with an aspect ratio within a preset range by judging whether the aspect ratio of the window is within a preset range.

[0101] based on Figure 4A In an embodiment, taking a rectangular foldable screen without split-screen as an example, see [link to example]. Figure 4B The diagram illustrates the relationship between the window aspect ratio change and the full-screen display orientation before and after the screen is folded. For example, as shown in the right figure, R0 is the window aspect ratio before the screen is folded, and R1 is the window aspect ratio after the screen is folded. If R1 falls within a preset range, the application interface's display orientation does not need to be rotated according to its current orientation; if R1 falls outside the preset range, the application interface's display orientation generally needs to be rotated according to the application's specified orientation.

[0102] See Figure 4C Taking the display screen in split-screen mode as an example Figure 4A The illustrated embodiments are provided for comparative explanation. Figure 4CIn the left two figures, the display screen can be a folding screen or a non-folding screen. If the display screen is a folding screen, the display screen can be in an unfolded state or a folded state. The key point is that each split-screen window on the display screen is a graphic with an aspect ratio in a preset interval. Figure 4C In the right two figures, the display screen can be a folding screen or a non-folding screen. If the display screen is a folding screen, the display screen can be in an unfolded state or a folded state. The key point is that each split-screen window on the display screen is a graphic with an aspect ratio not in a preset interval.

[0103] In the left upper figure, a multimedia file (a video in the figure) is being played in the left split-screen window. If a user clicks a full-screen button on an application interface to issue a full-screen instruction, it is determined whether the aspect ratio of the split-screen window is in a preset interval. Since the split-screen window is a graphic with an aspect ratio in a preset interval, the determination result is that the aspect ratio is in a preset interval. Therefore, in the left lower figure, the multimedia file is displayed in full screen according to the current display direction of the application interface.

[0104] In the right upper figure, a multimedia file (a video in the figure) is being played in the left split-screen window. If a user clicks a full-screen button on an application interface to issue a full-screen instruction, it is determined whether the aspect ratio of the split-screen window is in a preset interval. Since the split-screen window is a graphic with an aspect ratio not in a preset interval, the determination result is that the aspect ratio is not in a preset interval. Therefore, in the right lower figure, the multimedia file is displayed in full screen after rotating the direction of the multimedia file according to the display direction specified by the application.

[0105] In actual application, if the display screen does not display in split screen, generally, the window displaying the application interface is coincident with the complete display area of the screen to which the window belongs, that is, the window displaying the application interface is the complete display area of the screen to which the window belongs. In the case of known screen shape and size, it is not necessary to obtain the aspect ratio of the window. As long as it is known whether the screen is a graphic with an aspect ratio in a preset interval, the determination of whether the window is a graphic with an aspect ratio in a preset interval can be realized. If the display screen is not a folding screen, the screen herein refers to the display screen. If the display screen is a folding screen, the screen herein can be a complete screen or a sub-screen of the display screen. According to the principle, the present application further provides a flowchart of another embodiment of the full-screen display method of the present application. Figure 5A through Figure 10A The following embodiments are explained one by one.

[0106] Figure 5A The flowchart of another embodiment of the full-screen display method of the present application is shown.

[0107] In this embodiment, the display screen is a folding screen, and the display screen does not display in split screen. In the folded state, the sub-screen is a graphic with an aspect ratio in a preset interval, and in the unfolded state, the complete screen is a graphic with an aspect ratio not in a preset interval. Referring to the flowchart of another embodiment of the full-screen display method of the present application shown in FIG. 6, the following is explained. Figure 5BAs shown, when the display screen includes 2 sub-screens, example diagrams of the display screen in the fully folded state and the unfolded state are given.

[0108] As shown, the method can include: Figure 5A

[0109] Step 501: When an instruction to full-screen display the application interface is detected, determine the screen used by the window displaying the application interface; if the screen used is one sub-screen, execute step 502; if the screen used is a complete screen, execute step 503.

[0110] Step 502: In accordance with the current display direction of the application interface, full-screen display the application interface in the window, and this branch flow ends.

[0111] Step 503: In accordance with the display direction specified by the application, full-screen display the application interface in the window, and this branch flow ends.

[0112] In a possible implementation, if the display screen in the embodiment is split-screen displayed, and the display screen is split-screen displayed according to each sub-screen as one split-screen, the display application interface is one sub-screen, and the sub-screen is a graphic with a preset interval of aspect ratio. At this time, before the step of determining the screen used by the window displaying the application interface when an instruction to full-screen display the application interface is detected, the method can further include: determining whether the display screen is split-screen displayed; if not, executing the step of determining the screen used by the window displaying the application interface; and if yes, executing step 502.

[0113] Referring to Figure 5C , example diagrams of the embodiment are shown; in the diagram in the upper left corner, when the user clicks the full-screen button while watching a video in a sub-screen, in accordance with the method in Figure 5A , it is determined that the screen used is one sub-screen. Correspondingly, referring to the diagram shown in the lower left corner, the video is full-screen displayed in the sub-screen in accordance with the current display direction of the video playing program interface; Figure 5A

[0114] In the diagram in the upper right corner, when the user clicks the full-screen button while watching a video in a complete screen, in accordance with the method in Figure 5A , it is determined that the screen used is a complete screen. Correspondingly, referring to the diagram shown in the lower right corner, the video is full-screen displayed in the complete screen after rotating the direction of the video playing program interface.

[0115] Figure 6 A flowchart of another embodiment of the full-screen display method of the application is shown.

[0116] ​​In this embodiment, the display screen is a folding screen, and the display screen does not display in split screen mode; in the folding state, the sub-screen is a figure with an aspect ratio in a preset interval, and in the unfolded state, the complete screen is a figure with an aspect ratio not in the preset interval. For examples of the display screen, refer to Figure 5B , which are not described herein.

[0117] Since the display screen does not display in split screen mode, in the folding state, one sub-screen of the display screen displays the application interface, in the unfolded state, the complete screen displays the application interface, when changing from the folding state to the unfolded state, the complete screen displays the application interface, and when changing from the unfolded state to the folding state, one sub-screen displays the application interface. The folding state here can be an incomplete folding state or a complete folding state. In actual applications, the application does not limit which sub-screen displays the application interface.

[0118] At this time, as shown in Figure 6 , the method can include:

[0119] Step 601: When an instruction for full-screen display of an application interface is detected, judging the opening and closing state of the display screen; if the opening and closing state of the display screen is a folding state, executing step 603; if the opening and closing state of the display screen is an unfolded state, executing step 604; if the opening and closing state of the display screen is an opening and closing change state, executing step 602.

[0120] Step 602: Judging the change direction of the opening and closing state of the display screen, if the change direction is from the unfolded state to the folding state, executing step 603, and if the change direction is from the folding state to the unfolded state, executing step 604.

[0121] Step 603: According to the current display direction of the application interface, displaying the application interface in full screen in the window, and the branch process ends.

[0122] Step 604: According to the display direction specified by the application, displaying the application interface in full screen in the window, and the branch process ends.

[0123] In a possible implementation, if the display screen in this embodiment displays in split screen mode, and the display screen displays in split screen mode according to each sub-screen as a split screen, one sub-screen displays the application interface, and the sub-screen is a figure with an aspect ratio in a preset interval. At this time, when a full-screen instruction for the application interface is detected, before the step of judging the opening and closing state of the display screen, it can also include: judging whether the display screen displays in split screen mode, if not, executing the step of judging the opening and closing state of the display screen, and if yes, executing step 603.

[0124] Figure 6 For examples of the display screen, refer to Figure 5B and Figure 7Bwhich will not be described herein.

[0125] Figure 7A a flowchart of another embodiment of the full-screen display method of the present application.

[0126] In this embodiment, the display screen is a folding screen, and the display screen does not split-screen display; in the unfolded state, the full screen is a pattern with an aspect ratio not in the preset interval, and in the folded state, the sub-screen is a pattern with an aspect ratio in the preset interval. For examples of the display screen, see Figure 5B which will not be described herein.

[0127] Since the display screen does not split-screen display, when changing from the folded state to the unfolded state, the screen displaying the application interface changes from the sub-screen to the full screen, and when changing from the unfolded state to the folded state, the screen displaying the application interface changes from the full screen to a sub-screen. The folded state herein can be an incomplete folded state or a complete folded state. In actual applications, the specific sub-screen displaying the application interface is not limited by the present application.

[0128] At this time, as shown in Figure 7A the method can include:

[0129] Step 701: When detecting that the opening and closing state of the display screen starts to change, judging the change direction of the opening and closing state of the display screen; if the change direction is from the unfolded state to the folded state, executing step 702, and if the change direction is from the folded state to the unfolded state, executing step 703.

[0130] Step 702: In accordance with the current display direction of the application interface, full-screen displaying the application interface in the window, and this branch process ends.

[0131] Step 703: In accordance with the display direction specified by the application, full-screen displaying the application interface in the window, and this branch process ends.

[0132] In a possible implementation, if the display screen in this embodiment split-screen displays, and the display screen split-screen displays according to each sub-screen as a split screen, then a sub-screen displays the application interface, and the sub-screen is a pattern with an aspect ratio in the preset interval. At this time, when detecting that the opening and closing state of the display screen starts to change, before the step of judging the change direction of the opening and closing state of the display screen, it can further include: judging whether the display screen is split-screen displayed, if not split-screen displayed, executing the step of judging the change direction of the opening and closing state of the display screen, and if split-screen displayed, executing step 702.

[0133] Referring to Figure 7B In the upper left diagram, the user is full-screen watching a video on the full screen, in accordance with Figure 7AIf the display screen is folded at this time, it is determined that the change direction is from the unfolded state to the folded state. Correspondingly, referring to the lower right part of the figure, the video playing program interface is rotated and the video is displayed on the sub-screen in full screen.

[0134] In the upper right part of the figure, the user is watching the video in full screen on the complete screen. According to the current display direction of the video playing program interface, the video is displayed on the sub-screen in full screen. Figure 7A If the display screen is folded at this time, it is determined that the change direction is from the unfolded state to the folded state. Correspondingly, referring to the lower right part of the figure, the video playing program interface is rotated and the video is displayed on the sub-screen in full screen.

[0135] Figure 8A This is a flowchart of another embodiment of the full screen display method.

[0136] In this embodiment, the display screen is a folding screen, and the display screen is not split-screen displayed. In the unfolded state, the complete screen is a graphic with an aspect ratio in a preset interval, and in the folded state, the sub-screen is a graphic with an aspect ratio not in the preset interval. Referring to the figure, examples of the folded state and the unfolded state of the display screen are given. The folded state here can be an incomplete folded state or a complete folded state. Figure 8B

[0137] As shown in the figure, the method can include the following steps. Figure 8A

[0138] Step 801: When an instruction for full screen display of an application interface is detected, a screen used for a window displaying the application interface is determined. If the screen used is a complete screen, step 802 is executed; if the screen used is a sub-screen, step 803 is executed.

[0139] Step 802: According to the current display direction of the application interface, the application interface is displayed in full screen on the window. This branch flow ends.

[0140] Step 803: According to the display direction specified by the application, the application interface is displayed in full screen on the window. This branch flow ends.

[0141] In a possible implementation, if the display screen in this embodiment is split-screen displayed, and the display screen is split-screen displayed according to each sub-screen as a split screen, a sub-screen is used to display the application interface, and the sub-screen is a graphic with an aspect ratio not in a preset interval. At this time, before the step of determining the screen used for the window displaying the application interface, the method can further include the following steps: determining whether the display screen is split-screen displayed. If the display screen is not split-screen displayed, the step of determining the screen used for the window displaying the application interface is executed. If the display screen is split-screen displayed, step 803 is executed. ​​

[0142] Referring to Figure 8C , an example diagram of the embodiment is shown; in the diagram in the upper left corner, a user clicks a full screen button while watching a video in a sub-screen, and according to the method in Figure 8A , it is determined that a screen used is a sub-screen, and accordingly, referring to the diagram shown in the lower left corner, the direction of a video playing program interface is rotated and the video is displayed in full screen in the sub-screen; Figure 8A

[0143] In the diagram in the upper right corner, a user clicks a full screen button while watching a video in a full screen, and according to the method in Figure 8A , it is determined that a screen used is a full screen, and accordingly, referring to the diagram shown in the lower right corner, the video is displayed in full screen in the sub-screen according to the current display direction of the video playing program interface.

[0144] Figure 9 An example flowchart of another embodiment of the full screen display method of the present application is shown.

[0145] In this embodiment, the display screen is a folding screen, and the display screen is not split-screen displayed; in the folding state, the sub-screen is a figure whose aspect ratio is not in a preset interval, and in the unfolded state, the full screen is a figure whose aspect ratio is in the preset interval. The example of the display screen can be seen in Figure 8B , which is not described herein.

[0146] Since the display screen is not split-screen displayed, in the folding state, one sub-screen of the display screen displays an application program interface, in the unfolded state, the full screen displays the application program interface, when the folding state changes to the unfolded state, the full screen displays the application program interface, and when the unfolded state changes to the folding state, one sub-screen displays the application program interface. In actual application, the present application does not limit which sub-screen displays the application program interface.

[0147] At this time, as shown in Figure 9 , the method can include:

[0148] Step 901: when a full screen instruction for an application program interface is detected, the open and close state of the display screen is determined; if the open and close state of the display screen is the unfolded state, step 903 is executed; if the open and close state of the display screen is the folding state, step 904 is executed; if the open and close state of the display screen is the open and close change state, step 902 is executed;

[0149] Step 902: the change direction of the open and close state of the display screen is determined, if the change direction is that the folding state changes to the unfolded state, step 903 is executed, and if the change direction is that the unfolded state changes to the folding state, step 904 is executed.

[0150] ​Step 903: full-screen display the application interface in the window according to the current display direction of the application interface, and the branch flow ends.

[0151] Step 904: full-screen display the application interface in the window according to the display direction specified by the application, and the branch flow ends.

[0152] In a possible implementation, if the display screen in the embodiment is split-screen displayed, and the display screen is split-screen displayed according to each sub-screen as a split screen, the application interface is displayed on a sub-screen, and the sub-screen is a graphic with an aspect ratio not in the preset interval. At this time, before the step of judging the open and close state of the display screen, when the full-screen instruction for the application interface is detected, the method can further include: judging whether the display screen is split-screen displayed. If not, the step of judging the open and close state of the display screen is performed. If yes, step 904 is performed.

[0153] Figure 9 For examples of the display screen, refer to Figure 8C and Figure 10B , which will not be described herein again.

[0154] Figure 10A This is a flowchart of another embodiment of the full-screen display method.

[0155] In the embodiment, the display screen is a foldable screen, and the display screen is not split-screen displayed. In the folded state, the sub-screen is a graphic with an aspect ratio not in the preset interval, and in the unfolded state, the full screen is a graphic with an aspect ratio in the preset interval. The folded state can be an incomplete folded state or a complete folded state. For examples of the display screen, refer to Figure 8B , which will not be described herein again.

[0156] Since the display screen is not split-screen displayed, when the display screen changes from the folded state to the unfolded state, the screen displaying the application interface changes from the sub-screen to the full screen. When the display screen changes from the unfolded state to the folded state, the screen displaying the application interface changes from the full screen to a sub-screen. In actual applications, the application does not limit which sub-screen displays the application interface.

[0157] At this time, as shown in Figure 10A , the method can include:

[0158] Step 1001: when the open and close state of the display screen starts to change, judging the change direction of the open and close state of the display screen. If the change direction is that the folded state changes to the unfolded state, step 1002 is performed. If the change direction is that the unfolded state changes to the folded state, step 1003 is performed.

[0159] Step 1002: according to the current display direction of the application interface, the application interface is full-screen displayed in the window, and the branch flow ends.

[0160] Step 1003: according to the display direction specified by the application, the application interface is full-screen displayed in the window, and the branch flow ends.

[0161] In a possible implementation, if the application is a video playing program, if the change direction is from the unfolded state to the folded state, the full-screen display content of the application can be changed, for example, from the full-screen window to the detail page, which is not limited here.

[0162] In a possible implementation, if the display screen in the embodiment is split-screen displayed, and the display screen is split-screen displayed by taking each sub-screen as a split-screen, the application interface is displayed in a sub-screen, and the sub-screen is a graphic with a non-preset interval aspect ratio. At this time, when it is detected that the opening and closing state of the display screen starts to change, before the step of judging the change direction of the opening and closing state of the display screen, the method can further include: judging whether the display screen is split-screen displayed. If not, the step of judging the change direction of the opening and closing state of the display screen is executed. If split-screen displayed, step 1003 is executed.

[0163] Referring to Figure 10B , in the left upper figure, the user is full-screen watching a video in a sub-screen. According to the method shown in Figure 10A , if the display screen is unfolded at this time, it is judged that the change direction is from the folded state to the unfolded state. Correspondingly, referring to the left lower figure, the video is full-screen displayed in the complete screen according to the current display direction of the video playing program interface.

[0164] In the right upper figure, the user is full-screen watching a video in the complete screen. According to the method shown in Figure 10A , if the display screen is folded at this time, it is judged that the change direction is from the unfolded state to the folded state. Correspondingly, referring to the right lower figure, the video is full-screen displayed in the sub-screen after rotating the direction of the video playing program interface.

[0165] In the above Figure 5A through Figure 10A embodiment, the folded screen includes two sub-screens as an example, and those skilled in the art can extend the embodiments of the present application to the scene where the folded screen includes more than two sub-screens. The principle is that when the window displaying the application interface is the complete display area of the screen where the window is located, the shape of the window can be determined according to the shape of the screen where the window is located. Here, the embodiments are not listed one by one.

[0166] In a possible implementation, the determination of whether the window is a graphic with an aspect ratio in a preset interval and the full-screen display of the application interface can be performed by a system of the electronic device, for example, an Android system. At this time, referring to the implementation shown in FIG. 43, the method can include the following steps. Figure 11A

[0167] Step 1101: When the application detects an instruction to perform full-screen display on the application interface, the application sends a direction setting request to the system.

[0168] The specific implementation of the application detecting the instruction to perform full-screen display on the application interface can refer to the description in step 301, which is not described here.

[0169] In a possible implementation, taking the system as an Android system for example, the application sending the direction setting request to the system can include: the application sending setRequestedOrientation to the system.

[0170] Since the prior art is for a rectangular screen, the direction setting request sent by the application in the prior art includes the display direction of the application interface, and the display direction is: landscape or portrait. Specifically, if the application sends setRequestOrientation to the system, the parameter can be: LANDSCAPE or PORTRAIT; for example, setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) represents portrait, and setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) represents landscape. The application how to determine the display direction in the direction setting request is not limited by the present application.

[0171] Step 1102: The system receives the request, determines whether the window displaying the application interface is a graphic with an aspect ratio in a preset interval, and if the window is a graphic with an aspect ratio in a preset interval, performs step 1103, and if the window is not a graphic with an aspect ratio in a preset interval, performs step 1104.

[0172] How to determine whether the window is a graphic with an aspect ratio in a preset interval in this step can refer to various determination methods described in FIGS. 4-10, which are not described here.

[0173] Step 1103: The system displays the application interface in the window according to the current display direction of the application interface, and this branch process ends.

[0174] ​In this step, the system can modify the parameter configuration of setRequestedOrientation sent by the application to the system as: BEHIND, indicating that the display direction of the application interface follows the current display direction of the application interface, and the direction does not need to be rotated, for example, setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_BEHIND).

[0175] For example, for the following code, “landscape” or “portrait” can be replaced with “behind”.

[0176] <activity

[0177] android:configChanges=”…”

[0178] android:name=”.VideoPlayerActivity”

[0179] android:screenOrientation=”landscape” / >

[0180] Or

[0181] <activity

[0182] android:configChanges=”…”

[0183] android:name=”.VideoDetailActivity”

[0184] android:screenOrientation=”portrait” / >

[0185] For example, for the following code, “LANDSCAPE” or “PORTRAIT” can be replaced with “BEHIND”.

[0186]

[0187] Or

[0188] Public void onClick(view v){

[0189] setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

[0190] }

[0191] Step 1104: The system displays the application interface in the window in full screen according to the display orientation requested in the orientation setting request, and the branch flow ends.
