Patent Description:
Embodiments of the present invention relate to the field of terminal technologies, and in particular, to a split-screen processing method, a terminal device and a computer storage medium.

Currently, a terminal device may simultaneously run a plurality of applications (application) in the background, and a user may switch between different applications based on a requirement, to enter an interface on which the user wants to perform an operation.

To pursue better use experience, the user expects to divide a display screen of the terminal device into a plurality of subscreens. Different subscreens may present content of different applications, and the content on different subscreens does not affect each other. For example, when the user is watching a video, the user wants to handle other things at the same time, for example, editing an SMS message or processing instant messaging information, without interrupting the video.

For the current urgent requirement of the user for dividing one display screen into a plurality of subscreens, it is necessary to propose a corresponding technical solution, to conveniently and quickly present a plurality of subscreens on a display screen of a terminal device.

<CIT> provides a mobile terminal including a display unit to which multiple divisional screen regions are output, and a control unit that when an input for entering a division mode in which the display unit is divided into the multiple screen regions is received, generates a list region including a list of multiple applications, divides the display unit into first and second screen regions with the list region in between, and executes first and second applications selected from among the multiple applications on the first and second screen regions, respectively, in which the controller executes an application selected from among the multiple applications included in the list on the list region, and in which when an object included in the application being executed on the list region is selected, at least one of the first and second applications uses the selected object. <CIT> provides a mobile device for executing multiple applications. The mobile device includes a touch screen for displaying a first window where a first application is executed, a second window where a second application different from the first application is executed, and a controller for displaying an execution keys for executing the multiple applications, determining whether a simultaneous execution input for the first application and the second application is input or not, and if the simultaneous execution input is input then displaying the first application on the first window and the second application on the second window. <CIT> discloses a method of supporting divided screen areas and a mobile terminal employing the same. The method includes: generating input signals for one of sequentially and simultaneously activating a plurality of user functions; activating the user functions according to generated input signals; dividing a screen into divided screen areas that correspond to activated user functions; and outputting functional view areas associated with the activated user functions to the corresponding divided screen area
<CIT> discloses: A multiple window apparatus and method is provided. A method of displaying a plurality of display windows on a screen by using a device, the method includes displaying a first display window on the screen, receiving a user input that selects an object included in the first display window. displaying a list of applications matching a display mode of the first display window in response to the user input, and displaying a second display window including an execution result of an application selected from the list in the display mode.

Embodiments of the present invention disclose a split-screen processing method, a terminal device and a computer storage medium, so as to quickly divide a display screen into a plurality of subscreens, and display different content on different subscreens.

A first aspect discloses a split-screen processing method according to claim <NUM>.

In addition, because the user may implement screen splitting by performing an operation on an application in the application list, the user can implement, as required, screen splitting for an application that needs to be displayed, and the user does not need to open, after screen splitting, the application that needs to be used. This not only provides a flexible application startup and screen splitting manner, but also improves user experience. In addition, because the preset icon is displayed in a floating manner, display of the icon does not affect use of the terminal device by the user.

In a possible implementation, the first application list may include one or more of an application whose quantity of times of use is greater than a first threshold, an application whose association degree with a currently displayed application is greater than a third threshold, an application with to-be-processed information, and a recently used application, where a time difference between a time of using the application and a current time is less than a second threshold. It can be learned that the displayed application list is a list of applications determined based on a historical record of using an application by the user, whether to-be-processed information exists, and a degree of association with a current application. There is a relatively high probability that these applications are applications that the user needs to use, so that the user can quickly find a to-be-used application for screen splitting, and a screen splitting speed can be improved.

In a possible implementation, the first user operation may include a tap operation or a double-tap operation.

In a possible implementation, the terminal device displays to-be-selected applications when detecting an input third user operation on the first application list; when detecting an input fourth user operation on a second application, the terminal device adds the second application to the first application list to obtain a second application list; and the terminal device detects an input second user operation on the first application in the second application list. The to-be-selected applications are applications, in applications of the terminal device, other than the applications included in the first application list. The second application is any one of the to-be-selected applications. It can be learned that after the application list is determined based on the historical record of using the application by the user, whether to-be-processed information exists, and the degree of association with the current application, when an application required by the user is not in the list, the user may further add the required application to the application list, so as to perform screen splitting by using the application. The application may be started during screen splitting, which not only improves application startup efficiency, but also improves user experience.

In a possible implementation, the third user operation and the fourth user operation each may include a tap operation or a double-tap operation.

In a possible implementation, the terminal device hides the preset icon when detecting no input user operation on the preset icon within a preset time period. After a period in which the user does not use the preset icon reaches a specific time, the icon may be hidden, so as to reduce power consumption of the terminal device.

In a possible implementation, the terminal device displays the preset icon when detecting an input fifth user operation. It can be learned that when the user wants to use the icon, the user may perform an operation to display the icon. This can improve flexibility of the icon.

In a possible implementation, the fifth user operation may include a swipe operation.

In a possible implementation, the sixth user operation may include a tap operation, a double-tap operation, or a swipe operation.

In a possible implementation, when detecting an input seventh user operation on the first subscreen, the terminal device determines that the first subscreen is in a dragged state, and when detecting an input operation used to drag the first subscreen to an area of the second subscreen, the terminal device switches display positions of the first subscreen and the second subscreen. It can be learned that switching between the subscreens may be implemented by dragging the subscreens, so as to improve flexibility of switching between the subscreens.

In a possible implementation, the terminal device displays a split-screen thumbnail when detecting an input eighth user operation on the preset icon; and when detecting an input seventh user operation on a thumbnail corresponding to the first subscreen in the split-screen thumbnail, the terminal device determines that the first subscreen is in a dragged state. The terminal device switches display positions of the first subscreen and the second subscreen when detecting an input operation that is used to drag the thumbnail corresponding to the first subscreen to an area of a thumbnail corresponding to the second subscreen. It can be learned that switching between subscreens may be implemented by using a thumbnail. This can reduce an operation area of the user and improve user experience.

In a possible implementation, the seventh user operation may include an operation with a touch time greater than a fourth threshold, or an operation of double-tap with a touch time greater than a fourth threshold.

In a possible implementation, when detecting an input ninth user operation on the first subscreen, the terminal device determines that the first subscreen is in a dragged state; and the terminal device closes the first subscreen when detecting an input operation used to drag the first subscreen out of the screen. A subscreen and a corresponding application may be directly closed by dragging the subscreen, so that the subscreen and the corresponding application can be conveniently and quickly closed without affecting use of another application.

In a possible implementation, the terminal device displays the split-screen thumbnail when detecting an input tenth user operation on the preset icon, and the terminal device closes the first subscreen when detecting an input eleventh user operation on the thumbnail corresponding to the first subscreen in the split-screen thumbnail. It can be learned that a subscreen and a corresponding application may be closed by using a thumbnail, so that the subscreen and the corresponding application can be conveniently and quickly closed without affecting use of another application.

In a possible implementation, the eleventh user operation may be a tap operation, or may be an operation with a touch time greater than a fifth threshold.

<FIG> is a schematic flowchart of a split-screen processing method according to an embodiment of the present invention. The split-screen processing method is applied to a terminal device. The terminal device may be a terminal device on which a foldable screen is disposed, or may be a terminal device on which a flat screen is disposed, or may be a terminal device on which a touchscreen is disposed in another manner. This is not limited herein. As shown in <FIG>, the split-screen processing method may include the following steps.

<NUM>: Display a first interface including a preset icon.

The terminal device may display the first interface including the preset icon, and the preset icon is displayed in a floating manner, so that content currently displayed on a display screen is not affected. The first interface is an interface currently displayed by the terminal device, and may be a home screen interface, or may be an interface of any application.

<FIG> is a schematic diagram of displaying a preset icon by a terminal device according to an embodiment of the present invention. As shown in <FIG>, the preset icon may be a circular icon displayed in a lower right corner of the screen. <FIG> is a schematic diagram of adjusting a display position of a preset icon according to an embodiment of the present invention. As shown in <FIG>, the dashed line represents the preset icon before adjustment, and the solid line represents the preset icon after adjustment. <FIG> is a schematic diagram of adjusting a shape of a preset icon according to an embodiment of the present invention. As shown in <FIG>, a user may first perform an operation on the preset icon, for example, slide the current preset icon rightward. After detecting the operation, the terminal device may display an available preset icon. When the terminal device detects a tap operation performed by the user on a preset icon, the terminal device replaces the current preset icon with the preset icon that the user taps. <FIG> is a schematic diagram of adjusting a size of a preset icon according to an embodiment of the present invention. As shown in <FIG>, the dashed line represents the preset icon before adjustment, and the solid line represents the preset icon after adjustment.

The preset icon may be displayed when the screen is unlocked, or may be displayed when the screen is lit. In some embodiments, if a foldable screen is disposed on the terminal device, when detecting that the foldable screen is unfolded, the terminal device displays the first interface including the preset icon. In other words, the preset icon may be displayed when the screen is unfolded. In some embodiments, when detecting an input fifth user operation, the terminal device displays the preset icon. The fifth user operation may be a swipe operation, or may be another touch operation, or may be a voice operation, or may be a gesture operation. <FIG> is a schematic diagram of a user operation used to display a preset icon according to an embodiment of the present invention. As shown in <FIG>, the terminal device may display the preset icon when detecting a swipe operation, starting from a lower right corner in an upper left direction, performed by the user. Alternatively, the terminal device may display the preset icon when detecting a swipe operation, starting from a lower left corner in an upper right direction, performed by the user; or may display the preset icon when the terminal device detects another operation performed by the user.

When the terminal device detects no input user operation on the preset icon within a preset time period, the terminal device may hide the preset icon. In other words, when no operation performed by the user for the preset icon is detected within the period of time, it indicates that the user does not use the preset icon temporarily, and the preset icon may be automatically hidden, so as to reduce power consumption of the terminal device. Alternatively, the user may close the preset icon by performing an operation. For example, when detecting an operation of sliding, by the user, the preset icon to the lower right corner, the terminal device may close the preset icon.

<NUM>: Display a first application list when an input first user operation on the preset icon is detected.

After displaying the first interface including the preset icon, the terminal device may display the first application list when detecting the input first user operation on the preset icon. The first application list may include one or more of an application whose quantity of times of use is greater than a first threshold, an application whose association degree with a currently displayed application is greater than a third threshold, an application with to-be-processed information, and a recently used application, where a time difference between a time of using the application and a current time is less than a second threshold. The application whose quantity of times of use is greater than the first threshold is an application frequently used by the user, and may include only a frequently used split-screen application, or may include only a frequently used non-split-screen application, or may include a frequently used split-screen application and a frequently used non-split-screen application. The recently used application is an application recently used by the user, where a time difference between a time of using the application and a current time is less than the second threshold. The recently used application may include only a recently used split-screen application, or may include only a recently used non-split-screen application, or may include a recently used split-screen application and a recently used non-split-screen application. The application with to-be-processed information is an application that has an unprocessed new message.

The first user operation may be a tap operation, or may be a double-tap operation, or may be another touch operation, or may be a voice operation, or may be a gesture operation. <FIG> is a schematic diagram of displaying an application list after a user taps a preset icon according to an embodiment of the present invention. As shown in <FIG>, after detecting that the user taps the preset icon, the terminal device may display, around the preset icon, icons of applications in the application list, that is, triangles. One triangle represents one application icon. The figure shows icons of three applications. <FIG> is another schematic diagram of displaying an application list after a user taps a preset icon according to an embodiment of the present invention. As shown in <FIG>, after detecting that the user taps the preset icon, the terminal device displays, next to the preset icon, icons of applications in the application list, and the icons of the applications are arranged in a column. The application list may be displayed in a floating manner, so that display of the currently displayed application is not affected. The application list may be displayed at a fixed location on the display screen or around the preset icon. The application list may be arranged in columns, rows, or other manners.

In an embodiment, when detecting an input third user operation on the first application list, the terminal device may display to-be-selected applications, and when detecting an input fourth user operation on a second application, the terminal device adds the second application to the first application list to obtain a second application list. The to-be-selected applications are applications, in applications of the terminal device, other than the applications included in the first application list, that is, applications that are not in the first application list. The second application is any one of the to-be-selected applications. The third user operation and the fourth user operation may be tap operations, or may be double-tap operations, or may be other touch operations, or may be voice operations, or may be gesture operations. The third user operation and the fourth user operation may be the same or different. It can be learned that the first application list may include a selection button or a selection area. When detecting an operation performed by the user on the selection button or the selection area, the terminal device may display the to-be-selected applications. When detecting an operation performed by the user on an application in the displayed to-be-selected applications, the terminal device may add the application to the first application list to obtain the second application list. <FIG> is a schematic diagram of adding an application to the first application list by the user by using a selection button or a selection area according to an embodiment of the present invention. As shown in <FIG>, when detecting a tap operation performed by the user on the selection button or the selection area, the terminal device displays the to-be-selected applications. When detecting a tap operation performed by the user on an application in the to-be-selected applications, the terminal device adds the application to the first application list to obtain the second application list.

<NUM>: Divide the screen of the terminal device into two or more subscreens when an input second user operation on a first application in the first application list is detected, and display the first interface and the first application on a first subscreen and a second subscreen respectively.

After displaying the first application list, when detecting the input second user operation on the first application in the first application list, the terminal device may divide the screen of the terminal device into two or more subscreens, and display the first interface and the first application on the first subscreen and the second subscreen respectively. The first subscreen and the second subscreen are included in the two or more subscreens. The second user operation may be a tap operation, or may be a double-tap operation, or may be a swipe operation, or may be another touch operation, or may be a voice operation, or may be a gesture operation. In some embodiments, when the second application list is obtained from the first application list, the input second user operation detected by the terminal device is for the first application in the second application list.

Different operations, detected by the terminal device, performed by the user on an application in the first application list may result in different responses of the terminal device. <FIG> is a schematic diagram of performing a user operation on an application in the first application list to implement screen splitting according to an embodiment of the present invention. As shown in <FIG>, when the terminal device detects an operation, performed by the user, of touching and holding the first application in the first application list and sliding the first application to the left, the terminal device divides the display screen into two subscreens: a left subscreen and a right subscreen. The first interface may be displayed on the left subscreen, and the first application may be displayed on the right subscreen; or vice versa. <FIG> is another schematic diagram of performing a user operation on an application in the first application list to implement screen splitting according to an embodiment of the present invention. As shown in <FIG>, when the terminal device detects an operation, performed by the user, of touching and holding the first application in the first application list and sliding the first application upwards, the terminal device divides the display screen into two subscreens: an upper subscreen and a lower subscreen. The first interface may be displayed on the upper subscreen, and the first application may be displayed on the lower subscreen; or vice versa. <FIG> is still another schematic diagram of performing a user operation on an application in the first application list to implement screen splitting according to an embodiment not covered by the claims. As shown in <FIG>, when the terminal device detects an operation, performed by the user, of touching and holding the first application in the first application list and sliding the first application to the upper left, the terminal device may divide the display screen into two screens: a left <NUM>/<NUM> screen and a right full screen. The first interface may be displayed on the left <NUM>/<NUM> subscreen, and the first application may be displayed on the right subscreen; or vice versa.

<FIG> is still another schematic diagram of performing a user operation on an application in the first application list to implement screen splitting according to an embodiment not covered by the claims. As shown in <FIG>, when the terminal device detects an operation, performed by the user, of tapping the first application in the first application list, the terminal device may divide the display screen into two subscreens: an upper subscreen and a lower subscreen. The first interface may be displayed on the upper subscreen, and the first application may be displayed on the lower subscreen; or vice versa.

In some embodiments, when detecting an input sixth user operation on the first application in the first application list, the terminal device uses the first application to cover the currently displayed application. The sixth user operation may be a tap operation, or may be a double-tap operation, or may be a swipe operation, or may be another touch operation, or may be a voice operation, or may be a gesture operation. The second user operation is different from the sixth user operation. <FIG> is a schematic diagram of performing a user operation on the first application in the first application list to cover the first interface according to an embodiment not covered by the claims.

In an embodiment, when the terminal device is already in a screen split state, screen splitting may be performed again. <FIG> is still another schematic diagram of performing a user operation on an application in the first application list to implement screen splitting according to an embodiment of the present invention. As shown in <FIG>, when the terminal device detects an operation, performed by the user, of touching and holding the first application in the first application list and sliding the first application to the upper left, the terminal device may further divide the left subscreen into two subscreens: an upper subscreen and a lower subscreen. An application originally displayed on the left subscreen may be displayed on the upper left subscreen, and the first application may be displayed on the lower left subscreen; or vice versa.

In some embodiments, after the screen of the terminal device is split, locations of different subscreens may be switched by using a user operation. In an implementation, when detecting an input seventh user operation on the first subscreen, the terminal device may determine that the first subscreen is in a dragged state, and when detecting an input operation used to drag the first subscreen to an area of the second subscreen, the terminal device switches display positions of the first subscreen and the second subscreen. When an area that is in the second subscreen and that is covered by the first subscreen is greater than a threshold, for example, <NUM>% or <NUM>% of the area of the second subscreen, it may be determined that the first subscreen is dragged to the area of the second subscreen. The seventh user operation may be an operation with a touch time greater than a fourth threshold, or may be an operation of double-tap with a touch time greater than a fourth threshold, or may be another touch operation, or may be a voice operation, or may be a gesture operation. <FIG> is a schematic diagram of subscreen switching according to an embodiment of the present invention. As shown in <FIG>, when the terminal device detects a touch and hold operation performed by the user on the upper right subscreen, the upper right subscreen presents a floating and shaking state, indicating that the upper right subscreen enters a dragged state. When the terminal device detects a downward dragging operation performed by the user on the upper right subscreen in the dragged state, and the upper right subscreen enters an area of the lower right subscreen, it indicates that the lower right subscreen is a screen for switching, and the lower right subscreen may also present a floating and shaking state. After detecting that the user's finger leaves the screen, the terminal device may switch the display positions of the upper right subscreen and the lower right subscreen. <FIG> is another schematic diagram of subscreen switching according to an embodiment of the present invention.

After detecting that the user's finger leaves the screen, the terminal device may switch the display positions of the upper right subscreen and the lower right subscreen.

In another implementation, the terminal device displays a split-screen thumbnail when detecting an input eighth user operation on the preset icon; and when detecting an input seventh user operation on a thumbnail corresponding to the first subscreen in the split-screen thumbnail, the terminal device determines that the first subscreen is in a dragged state. The terminal device switches display positions of the first subscreen and the second subscreen when detecting an input operation that is used to drag the thumbnail corresponding to the first subscreen to an area of a thumbnail corresponding to the second subscreen. <FIG> is still another schematic diagram of subscreen switching according to an embodiment of the present invention. As shown in <FIG>, the terminal device may display a split-screen thumbnail when detecting a double-tap operation performed by the user on the preset icon; and when detecting a touch and hold operation performed on a thumbnail corresponding to the upper right subscreen, the upper right subscreen presents a floating and shaking state, indicating that the upper right subscreen enters a dragged state. When it is detected that the user performs a downward dragging operation on the thumbnail corresponding to the upper right subscreen, and the upper right subscreen enters an area of the lower right subscreen, it indicates that the lower right subscreen is a screen for switching, and the lower right subscreen also presents a floating and shaking state. After detecting that the user's finger leaves the screen, the terminal device switches display positions of the upper right subscreen and the lower right subscreen.

In some embodiments, after the terminal device splits the screen, any subscreen of the current split screen may be closed through a user operation. In an implementation, when detecting an input ninth user operation on the first subscreen, the terminal device determines that the first subscreen is in a dragged state; and the terminal device closes the first subscreen when detecting an input operation used to drag the first subscreen out of the screen. <FIG> is a schematic diagram of closing a subscreen according to an embodiment of the present invention.
