How does touchscreen work?
In: Technology
theres resistive and capacative
The idea is that you have a extra layer on the screen that uses a physical atribute to detect you touching the screen
Resistve it was 2 layers that had a grid of dots, so depending on which dots from the 2 layers touched, you could tell where someone was touching.
Capacitive is similar but with 1 grid and 1 layer, the grid has a low voltage electric current through it, and when something conductive like your finger touches it, it creates a capacitor (basically a buildup of electricity there), by measuring that you can calculate where a use is touching.
