Detailed explanation-1: -Resistive touchscreens work with all types of objects. You can control them using a bare finger, a stylus or a gloved finger. Resistive touchscreens are comprised of multiple layers, each of which contains electrodes. The layers are separated by air or inert gas.
Detailed explanation-2: -Capacitive touchscreen panels must be touched with a finger, a special capacitive pen or a glove.
Detailed explanation-3: -Unlike resistive touchscreens, capacitive screens do not rely on finger pressure. Instead, they work with anything that holds an electrical charge-including human skin.
Detailed explanation-4: -Digital audio players, mobile phones, and tablet computers will sometimes use capacitive sensing touchscreens as input devices. Capacitive sensors can also replace mechanical buttons.
