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.

A touch screen is not programmed. It is an input output device.
The software of the device basically sends a signal to the screen to indicate which pixels to illuminate.
The touch part of the device is based on measuring something called capacitance to establish where on the screen you are touching.
