Both of the aforementioned applications are hereby incorporated by reference in their entireties.

TECHNICAL FIELD

This application relates to the field of communications technologies, and in particular, to a display method and a device.

BACKGROUND

With the development of electronic technologies, functions of intelligent terminals (such as mobile phones) are increasing, and users are increasingly relying on the mobile phones. For example, a mobile phone not only can be used as a communication or entertainment tool, but also can be used as a mobile office tool. For example, a user can use the mobile phone to send and receive work emails and process work files. However, a limitation of a screen of the mobile phone makes a mobile office far less convenient than a Personal Computer (PC) office.

To facilitate the use of mobile phone resources for a remote office, a mobile phone may be connected to an external display apparatus, so that the mobile phone can project display content on the external display apparatus. A user can use the mobile phone as a touchpad for a large-screen display, to control content displayed on the external display apparatus. Alternatively, a user can use a keyboard and/or a mouse that are/is connected to the external display apparatus, to control content displayed on the external display apparatus.

However, in the process in which the mobile phone projects the display content on the external display apparatus, the mobile phone may be used only as a control end (such as a control panel) or a supply source of the display content, and the mobile phone and the external display apparatus cannot display different content.

SUMMARY

This application provides a display method and a device, to display different content on a terminal and an external display apparatus, and control, on the terminal, permission to display an application on a desktop of the external display apparatus.

To achieve the foregoing objectives, this application uses the following technical solutions:

According to a first aspect, this application provides a display method. The method may be applied to a terminal, and the terminal is connected to an external display apparatus. The display method includes: displaying, by the terminal, a first screen, and instructing the external display apparatus to display a first desktop including a first application but not including a second application, where the first screen is different from the first desktop; and displaying, by the terminal in response to a first input of a user on the first screen, a second screen including the first application and the second application on the terminal, and instructing the external display apparatus to display a second desktop including the first application and the second application.

According to the display method provided in this application, the terminal may display, in response to the first input of the user on the first screen, the second screen including the first application and the second application on the terminal, and instruct to switch a displayed screen of the external display apparatus from the “first desktop including the first application but not including the second application” to the “second desktop including the first application and the second application”. In other words, in this application, the terminal can display a displayed screen (the first screen) related to content of a desktop (the first desktop) displayed by the external display apparatus, and the terminal can correspondingly switch, in response to an input on the related displayed screen (the first screen), the content displayed on the desktop of the external display apparatus. For example, an application in the terminal is added to the desktop of the external display apparatus, so that the added application can also be used by using the external display apparatus.

With reference to the first aspect, in a first implementation, after the terminal receives the first input on the first screen, the applications included in the second screen displayed by the terminal are the same as or different from the applications included in the second desktop.

In other words, the terminal may display the first desktop in the preset default display mode (the first display mode). The first display mode is a display mode adapted to a display screen of the terminal, or the first display mode is a display mode adapted to the external display apparatus.

With reference to the fifth implementation of the first aspect, in a sixth implementation, after the “instructing, by the terminal, the external display apparatus to display a first desktop including a first application but not including a second application”, the method in this application may further include: instructing, by the terminal in response to a second input of the external device for a mode switching option on the first desktop, the external display apparatus to display the first desktop in a second display mode; or instructing, by the terminal in response to a third input of the user on the terminal, the external display apparatus to display the first desktop in a second display mode.
