This application provides a screen
casting control method and a
display device. When the
display device establishes a device identification interaction link with an electronic device and receives a screen
casting management request from the electronic device, it actively launches the target application for screen
casting management. Based on the determined
interconnection protocol corresponding to the electronic device, it completes
pairing and connection with the electronic device, obtains the application
list sent by the electronic device, and displays the identifiers of each application in the application
list on the target application. Subsequently, in response to the user's selection operation of the
application identifier, the
display device sends the corresponding application launch command to the electronic device, allowing the user to directly select the application to be cast on the
large screen. After receiving the video
stream generated by the virtual display interface of the application corresponding to the launch command sent by the electronic device, the display device displays the screen corresponding to the video
stream. This realizes the display device's
active control and process management of the screen casting process, improves the interactive flexibility of the screen casting operation, and optimizes the user experience.
