Overview
There is a screen, powered without battery or cable. How does it display the images? You may think it is impossible. But with the help of NFC and E-Paper technology, this kind of screen has made it happen.
If you have a smartphone that has the NFC function, you can use your phone to control this screen and transmit images to it. Then the screen will remain the image for weeks without power until you transmit another image.
