How Touch Screens Work

Touch Screens work  instantly  with  All  programs - Just like a mouse.
    Simply touch the screen to respond, explore or create with your computer.
    Choose menu items, press buttons, move objects - simply by touching the screen.

ADD-On  touch screens are external frames with a clear see-through touch screen.
    They mount outside onto the monitor bezel. The controller is built into their frame.
    Some require power from a wall connection, others tap into the keyboard power.

BUILT-In touch screens are internal, heavy-duty touch screens mounted directly onto the monitor. Controllers are usually inside the monitor but can be external.
