(EN) Screen projection method, system and related device
(ZH) 一种投屏方法、系统及相关装置
Abrégé
(EN) 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.
(ZH) 一种投屏方法、系统及相关装置。本申请公开了一种一种投屏方法,包括:首先,电子设备在所述电子设备的显示屏上显示M个应用界面,M为大于1的整数。然后,电子设备接收第一选择操作,根据第一选择操作确定N个应用界面。其中,第一选择操作用于供所述电子设备从所述M个应用界面中确定出所述N个应用界面,N为小于或等于M的正整数。接着,响应于第一选择操作,电子设备向外部显示设备发送第一数据,该第一数据用于外部显示设备显示上述N个应用界面。实现了电子设备在分屏显示多个应用界面时,能够选择多个应用界面中的一个或多个投射至大屏显示器上,确保了涉及用户隐私的应用界面,需要经过用户同意确认才进行投屏,保护了用户的隐私。
