The "transparent screen" is an optical illusion where the screen of your phone or notebook looks as if it is see-through. This trick can be done with any device with a screen, such as laptops, smartphones, tablets, and so on. The trick itself is quite easy to implement, and depending on your imagination, the results can be rather mind-boggling.
You just need to take a picture of a background – it could be your keyboard, your hand, your face – then apply this as a wallpaper or background to your device.
Then, it takes some strategic placement of the phone on the actual surface of the background picture you just used, a little adjustment to the size of the photos (you may need to do a little bit of zooming) to complete the illusion and voilà! Magic!
