How does my phone’s touchscreen work when the glass is shattered?

2.83K views

I understand that the glass of my phone’s touchscreen is called the “digitizer” and it somehow detects my finger using electricity. Somehow, this screen is conducting current. How can it conduct current and still detect my finger when it’s shattered, glass pieces stabbing me in the finger as I swipe?

Yes, I need a new screen.

The digitizer is actually a transparent conductive mesh on a plastic layer underneath the glass, usually glued to the back. Your fingers interrupt the electric field it generates.

That’s why you can cover it all up with a screen protector and it still works, and why you barely have to touch the screen to register a touch.
