Best Answer

Capacitors are used on touch screen technology. mystery of using capacitor in touch screen is the working principle of capacitor .

when you touch the screen the distance between two plates inside screen will change(by pressing) and this will cause the change in capacitance and hence in voltage and this signal fed to processor to process it. and that behind the use of capacitor in touch screen.
