A touch screen is a control interface. It is a screen allowing for the visualization of information emitted by an LCD display placed directly behind it. The touch screen, as its name indicates, is sensitive to touch, allowing interaction between the user and the interface. By touching and lightly pressing on displayed data such as pictograms or words displayed on the screen, the function is then transmitted to the processor and interpreted in order to provide the desired result. This technology is a perfect alternative for applications which normally require a mouse, such as web browsers and other types of interfaces.
