A large 4.5-meter-tall and 15-meter-long LED screen to be used for publicity purposes was unveiled in the departure area of the T2 terminal at Pudong International Airport in recent days. This "magic" wall features smart sensing and interactive technologies, allowing human-machine interaction.

Currently, when passengers or visitors walk by it, the view of the expo displayed on the screen flips in relation to them, while displaying the logo, mascot, transportation guidance, and other information about the China International Import Expo.

After the expo, the screen will feature a forest scene. When visitors walk closer, flowers will bloom and butterflies appear.
