Abstract: The screen projection display method includes: After receiving screen projection request information sent by a source device, a target device obtains window data of an application enabled by the source device, where the window data includes display content corresponding to at least two windows opened in a same application enabled by the source device; and the target device displays the window data of the enabled application. The target device onto which a screen is to be projected obtains the window data of the application enabled by the source device. The window data not only includes content of a currently visible window on the source device, but also includes content of a window that is enabled by the source device but is invisible. The target device displays the window data on a display interface of the target device.
