The solution provided by the present disclosure will be described in detail below.
Fig. 1 illustrates a flowchart of a screen projection method of a terminal according to a first exemplary embodiment of the present disclosure. Referring to fig. 1, the screen projection method of the terminal includes steps S110 to S130. In a first exemplary embodiment, a mobile phone is taken as an example of a terminal, and the terminal includes a main display for displaying a main display window interface.
In step S110, a screen projection selection command is received, and option interfaces of mirror screen projection and application screen projection are provided.
In some embodiments, a screen projection selection command from a user can be received by the screen projection device, and an option interface for mirroring screen projection and application screen projection is provided. The option interfaces of the "mirror image projection" and the "application projection" may be implemented in the form of buttons, which may be suspended on the main display screen of the terminal in an opaque or semi-transparent manner, or may be semi-hidden at the boundary of the main display screen. However, the above is merely an example, and the present disclosure is not limited thereto, and the above-described buttons may be presented at any suitable position of the main display screen in any suitable manner. Furthermore, the option interfaces of "mirror projection" and "application projection" may be implemented in any other graphical user interface besides the button approach.
In step S120, when a selection command of an application screen projection is received and a response of a first application of a selected screen projection is received, a first screen projection window interface is established based on the selection command of the application screen projection, and the first screen projection window interface is projected to a selected external display device, where the first screen projection window interface includes at least a portion of content of the first application, and the first screen projection window interface is not associated with a main display screen window interface.
In some embodiments, when the screen projecting device receives a selection command of application screen projecting from a user and receives a response of a first application of a selected screen projecting adapted to the screen projecting method of the terminal of the present disclosure, the screen projecting device may establish a first screen projecting window interface based on the selection command of application screen projecting and project the first screen projecting window interface to the selected external display device. The first screen-projected window interface includes at least a portion of content of the first application, and in an example, the first screen-projected window interface can include specified content of the first application. For example, at least a portion of the content of the first application may include highlight content of the first application and may not include the status bar, the notification bar, and a portion of the desktop content. Further, for example, the specified content of the first application may include core content of the first application, and may not include a status bar, a notification bar, a portion of desktop content, and non-core content that is less associated with the core content of the first application. In an example, at least a portion of the content of the first application may be displayed in a split screen manner in the external display device, the split screen manner including, but not limited to, a top-bottom split screen, a left-right split screen, and the like, and the split screen may include a plurality of split screens. In an example, the at least a portion of the content of the first application includes, but is not limited to, being displayed in a temporal order, and the content of the first application may be truncated to be displayed in a random order or any designated order. In an example, the at least a portion of the content of the first application includes, but is not limited to, being displayed at a predetermined rate of the content of the first application, the content of the first application may be displayed at a fast forward or slow rate, or at any designated non-uniform rate. However, the above are merely examples, and the present disclosure is not limited thereto.
For example, when the first application is a video player, at least a portion of the content of the first application may be video and audio content played by the video player, but does not include a status bar, a notification bar, a portion of desktop content, and the like. Further, for example, at least a part of the content of the first application may also be the designated content of the first application, the designated content may be only a part of the video and audio content played by the video player, the only part of the content may be the content located in the center of the screen in the video content played by the video player, or may be the content that needs the focus, or may be the content of at least a part of the details thereof, and so on.
In some embodiments, the first screen-projecting window interface is not associated with a primary display screen window interface, and the primary display screen is used to display the primary display screen window interface, so that when the first screen-projecting window interface is projected onto the selected external display device, the terminal may be switched to another application, or may be locked without affecting the external display device to display the first screen-projecting window interface. In an example, when a first screen-projecting window interface is projected to a selected external display device, a first application selected for screen projection may run in a background of the terminal, after which a user may use the terminal to execute various other applications to operate the terminal while viewing the external display device; alternatively, the user may lock the terminal screen so that the first application is viewed on a larger screen at the external display device.
In step S130, when a selection command of mirror image screen projection is received, a main display screen window interface is projected to the selected external display device.
In some implementations, when the screen projection device receives a selection command from a user's mirror screen projection, the main display screen window interface can be projected by the screen projection device to the selected external display device. At this time, since the external display device completely mirrors the main display screen window interface, the terminal needs to continuously execute and display the first application; if the terminal is locked, the external display device cannot display the first application.
In the first exemplary embodiment of the present disclosure, since the option interfaces of the mirror image screen projection and the application screen projection are provided, which can be selected by the user, the user can flexibly select the screen projection mode according to the requirement, and the flexibility of the screen projection operation is improved.
In addition, when the user selects the application screen projection mode, the user can use other applications of the terminal at will without influencing the display of the selected screen projection application by the external display device, and the convenience of the terminal is improved.
In addition, when the application selected for screen projection is projected to the external display device, the external display device can display the designated content of the application selected for screen projection, and the display pertinence and diversity are improved.
Fig. 2 illustrates a flowchart of a screen projection method of a terminal according to a second exemplary embodiment of the present disclosure. Referring to fig. 2, the screen projection method of the terminal includes steps S210 to S240. In a second exemplary embodiment, a mobile phone is taken as an example of a terminal, and the terminal includes a main display for displaying a main display window interface.
In step S210, a screen projection selection command is received, and option interfaces of mirror screen projection and application screen projection are provided.
In step S220, when a selection command of an application screen projection is received and a response of a first application of a selected screen projection is received, a first screen projection window interface is established based on the selection command of the application screen projection, and the first screen projection window interface is projected to a selected external display device, where the first screen projection window interface includes at least a portion of content of the first application, and the first screen projection window interface is not associated with a main display screen window interface.
In step S230, when a selection command of an application screen projection is received and a response of the first application is not received, a second screen projection window interface is established based on the selection command of the application screen projection, and the second screen projection window interface is projected to the selected external display device, where the second screen projection window interface includes all contents of the first application, and the second screen projection window interface is not associated with the first screen projection window interface and the main display screen window interface.
In an example, when the screen projecting device receives a selection command of an application screen projecting without receiving a response of a first application that is not adapted to the screen projecting method of the terminal of the present disclosure, the screen projecting device may establish a second screen projecting window interface based on the selection command of the application screen projecting and project the second screen projecting window interface to the selected external display device. In an example, the second screen projection window interface includes the entire content of the first application. For example, the entire content of the first application includes the entire content displayed by executing the first application, which may or may not include a status bar, a notification bar, a portion of desktop content. In an example, the entire content of the first application may be displayed in the external display device in a split screen manner including, but not limited to, a top-bottom split screen, a left-right split screen, and the like, which may include a plurality of split screens. In an example, the entire content of the first application includes, but is not limited to, being displayed in a temporal order, and the content of the first application may be truncated into segments to be displayed in a random order or in any specified order. In an example, the entire content of the first application includes, but is not limited to, being displayed at a predetermined rate of the content of the first application, the content of the first application may be displayed at a fast forward or slow rate, or at any designated non-uniform rate. However, the above are merely examples, and the present disclosure is not limited thereto.
In an example, the second screen projecting window interface is not associated with the first screen projecting window interface and the main display screen window interface, and thus, when projecting the second screen projecting window interface to the selected external display device, the terminal may be switched to other applications or may be locked without affecting the external display device to display the second screen projecting window interface.
In step S240, when a selection command of mirror screen projection is received, a main display screen window interface is projected to the selected external display device.
In the second exemplary embodiment of the present disclosure, when the application selected for screen projection is not adapted to the screen projection apparatus of the present disclosure, the user can still use other applications of the terminal at will without affecting the external display apparatus to display the application selected for screen projection, which improves the convenience of using the terminal and expands the application range of the present disclosure.
Fig. 3 illustrates a flowchart of a screen projection method of a terminal according to a third exemplary embodiment of the present disclosure. Referring to fig. 3, the screen projection method of the terminal includes steps S310 to S340. In a third exemplary embodiment, a mobile phone is taken as an example of a terminal, and the terminal includes a main display for displaying a main display window interface.
In step S310, a screen projection selection command is received, and option interfaces of mirror screen projection and application screen projection are provided.
In step S320, when a selection command of an application screen projection is received and a response of a first application of a selected screen projection is received, a first screen projection window interface is established based on the selection command of the application screen projection, and the first screen projection window interface is projected to a selected external display device, where the first screen projection window interface includes at least a portion of content of the first application, and the first screen projection window interface is not associated with a main display screen window interface.
In step S330, when a selection command for application screen projection is received without receiving a response of the first application, an image of at least a portion of the content of the first application is intercepted and projected to the selected external display device.
In an example, when the screen-projecting device receives a selection command of application screen projection without receiving a response of the first application that is not adapted to the screen-projecting method of the terminal of the present disclosure, the screen-projecting device may intercept an image of at least a portion of the content of the first application and project the image to the selected external display device. In an example, the image of at least a portion of the content of the first application may include at least a portion of an image of any of the entire content of the first application, including but not limited to one image, but may be a mosaic of multiple images in a split screen fashion, or may be an image of a combination of multiple images in any suitable manner. The image of at least a portion of the content of the first application may not include the status bar, the notification bar, a portion of the desktop content.
