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.
In: Technology
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.
The digitizer is a separate layer from the glass. If the glass break is bad enough, it will also affect the digitzer, thus affecting the touch screen.
In my experience repairing these, usually only iPad’s suffer from touchscreen issues after a glass break. They seem to use a glass-like digitizer layer. Where as most other devices have a plastic-like digitizer layer.
