Capacitive touchscreens work by sensing the conductive properties of an object, usually the skin on your fingertip. They are more responsive than a resistive screen when it comes to gestures such as swiping and pinching. Capacitive touchscreens can also be operated while wearing certain types of gloves.
A Resistive touchscreen requires a touch with a certain amount of force applied to its surface. The touchscreen consists of a flexible film upper layer and a rigid lower layer. When the screen is pressed, the top layer is pushed onto the bottom layer — the technology senses a change in electrical voltage at the terminal outputs as the flexible and rigid layers come into contact with each other and registers input. Resistive touchscreens can be operated with a finger, a fingernail, a stylus or any other pointing object. However this technology is rapidly disappearing and we address some of the challenges why in our article on RTP technology.
