I definitely take this technology for granted, but on occasion I find myself blown away by how they do this. Especially in some applications where you can zoom in and it still works flawlessly. It’s almost as though every pixel is programmed in an ever changing screen.
I’m very un-techsavvy so I hope I’m posting in the right place.

The conducting layer is connected to a low voltage so that for a short time, there is a tiny electric current on the screen. This leaves it with a small electric charge. When your finger touches the screen, some of the small electrical charge flows on to it at that location. The program will know the location of your finger….the programmer will have a template in the background coded to do a function based on where you touch on the screen.
