What is a capacitive touch screen and how does it work in phones?

1. 1. A capacitive touch screen is a control technology that is fitted beneath a smartphone screen or display.
   2. It must be touched by a finger for conductive contact. Conductive contact refers to the direct contact between the finger and the phone screen.
   3. Also called Capacitive Touch Display, it works through electrical charges that are usually coated within the smartphone screen.
   4. Once your finger touches a particular part, some of the electrical charges are quickly drawn to that screen area.

   6. Capacitive touch screens have high clarity and are smooth with lighter contact and greater accuracy.
   7. Most modern smartphones and tablets rely on capacitive touch.
