TERMINAL DEVICE, METHOD AND SYSTEM FOR REALIZING SCREEN PROJECTION WITH ONE TOUCH USING REMOTE CONTROL Russian patent published in 2022 - IPC H04N21/40 H04B5/00 

FIELD: short distance communication.

SUBSTANCE: invention relates to the field of short distance communication and, in particular, to the field of screen projection using NFC. To achieve the effect, the screen projection system comprises a remote control, a terminal device and a display. Wherein, the remote control contains an NFC tag, wherein the NFC tag contains an identification code, the terminal device has an NFC function and is configured to display, after the terminal device touches the NFC tag of the remote control for the first time, the first pop-up window that contains a list of display devices, and the list display devices contains the name of the display devices, receiving the first operation from the user, and the first operation is used to select the display device, store the identification code of the NFC tag, display the first interface. At the same time, the display device is configured to display, in response to the first operation, a second pop-up window, which contains prompt information that is used to prompt the terminal device to request a connection with the display device, and display, in response to the second user operation, the first interface, wherein the second operation is allowing the terminal device to establish a connection with the display device.

EFFECT: acceleration of the screen projection implementation.
