The touch concept has gained widespread popularity in mobile technology. The layers become conductive when pressure is applied to a spot, and coordinates are sent to the processor. Typically, the touchscreen component is attached directly to the top of the glass LCD panel.
Touchscreens, touch screens, touch panels or touchscreen panels are display overlays which have the ability to display and receive information on the same screen. The effect of such overlays allows a display to be used as an input device, removing the keyboard and/or the mouse as the primary input device for interacting with the display's content. Such displays can be attached to computers or, as terminals, to networks.
