Abstract

The invention discloses a screen projection method and system and a related device. The invention discloses a screen projection method which comprises the steps that firstly, an electronic device displays M application interfaces on a display screen of the electronic device, and M is an integer larger than 1; then, the electronic equipment receives the first selection operation, and N applicationinterfaces are determined according to the first selection operation; wherein the first selection operation is used for the electronic device to determine the N application interfaces from the M application interfaces, and N is a positive integer smaller than or equal to M. Then, in response to the first selection operation, the electronic device sends first data to an external display device, andthe first data is used for the external display device to display the N application interfaces. When the electronic equipment displays a plurality of application interfaces in a split-screen mode, one or more of the application interfaces can be selected to be projected to the large-screen display, it is guaranteed that the application interface involving privacy of a user needs to be confirmed by the user and then subjected to screen projection, and the privacy of the user is protected.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a screen projection method, system and related devices. Background technique [0002] With the development of digital technology, personal computer (personal computer, PC) conversion of electronic devices such as mobile phones is one of the important means to realize mobile office. Specifically, electronic devices such as mobile phones can project the display content on the screen of the mobile phone to a large-screen display such as a PC through a wireless video display (Wi-Fi-Display) function or a Microsoft continuum (continuum) function. [0003] At present, the screens of mobile phones and other electronic devices are getting bigger and bigger. In order to give full play to the application value of large screens, people have developed split-screen display technology, so that mobile phones and other electronic devices can simultaneously display multiple appl...
