How Do Touchscreens Work?

Question

I’ve always been fascinated by touchscreens. Could someone explain in simple terms how touchscreens detect and respond to our touch inputs?

Answer 1

there are tiny wires going across the screen in a grid pattern, so small that you can’t see them, that have electricity flowing through them. Your finger interferes with that flow and the location of the interference is communicated to the software on the device and updates the screen image to reflect the changes, such as launching an app.
