Extracted from the Wikipedia article Touchscreen.
A touchscreen (or touch screen) is a type of display that can detect touch input from a user to do a specific task. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device. Touchscreens are commonly found in smartphones, tablets, laptops, and other electronic devices. The display is often an LCD, AMOLED or OLED display.
