This method requires higher requirements, requiring that the TV is a smart screen and the mobile phone is an HW mobile phone, so that one-click screen projection can be realized between the mobile phone and the TV through NFC function. We only need to use the back of Huawei's mobile phone and gently touch the remote control of the smart screen to project the mirror image of the mobile phone screen onto the smart screen TV.

2. Screen projection is performed by screen projection software.

If there is no Huawei smart screen at home, it is just an ordinary smart TV, which can also be realized by screen projection software. There are many kinds of screen projection software, here we take Leibo screen projection as an example. Install the "music broadcast projection screen" on the smart TV, and when it is opened on the smart TV, the projection code will be displayed.
