How does Apple's mobile phone project the screen onto the projector?

Apple's mobile phone can realize screen projection through AirPlay function. The following are the steps of screen projection:

Make sure that your Apple phone and the device you want to project (such as a TV or projector) are connected to the same Wi-Fi network.

Slide out of the control center on the Apple phone. On iPhone X or later, slide down the upper right corner of the screen. On iPhone 8 or earlier, slide the bottom of the screen up.

In the music control area or screen mirror area of the control center, you will see an AirPlay icon (with a rectangle in the triangle). Click this icon.

In the pop-up menu, you will see a list of devices that can be used for screen projection. Select the device on which you want to project the screen.

If necessary, enter the password of the projection device.

After the screen projection is successful, the screen content of your Apple phone will be displayed on the screen projection device.

Please note that not all devices support the AirPlay function. If the device doesn't support AirPlay function or has no LAN, you can use AirDroid Cast for screen projection:

1. Install AirDroid Cast on Apple mobile phones and receiving screen projection devices, such as mobile phones, tablets, computers and televisions.

2.AirDroid Cast is turned on on both Apple phones and receiving projection devices.

3. Enter the screen projection code on the screen projection device of Apple mobile phone.

4. After the connection is successful, the mobile phone screen will be displayed on the screen projection device.
