No the laptop basically monitors the electrical field around the screen and measures the change in capacitance (electric changes caused by your finger on the screen). These electronic devices monitor changes in electrical currents running through the screens. The touchscreens include a layer of capacitive, or electricity-storing, material. ... The circuitry inside the screen can then sense changes in electrical charge at each point along the grid.
Sorry, there was a problem. Please try again later.Yes the touch screen is sensitive.
