A touchscreen consists of a display and a touch panel. A control is usually already integrated. Some call the touch display screen only the touch panel. In any case, however, it is about the possibility of making entries on a larger area in order to read outputs at the same time or to display keypads and input or hide. Vandal-proof glass panes are required for POI stations, in industry and medical technology it is necessary that the touch screen can also be operated with gloves (resistive touch panel).

Touch screens are also advantageous for multilingualism. Inputs can be made more intuitive, double key presses are no longer necessary.

Typical representatives of touch screens are the EA eDIPTFT displays and the EA uniTFT displays (linked here). You can buy these touchscreens in different sizes and designs.
