Abstract
The present application provides a screen projection method, a receiving end device, and a sending end device. The receiving end device performs active wireless scanning and searching on the sending end device, and when the sending end device is scanned, establishes a wireless connection with the sending end device; and once the wireless connection is established, the receiving end device automatically sends a screen projection code to the connected sending end device, and the sending end device may prompt a user to perform a screen projection operation by means of displaying the screen projection code. In this process, there is no need for the user to perform complicated manual operations, the sending end device can automatically acquire the screen projection code, and prompts the user to perform the screen projection operation in a timely manner, thereby improving the timeliness of the screen projection operation.
