What happens when you calibrate a touch screen?

I calibrated my touch screen phone and wasn't sure what it did.

    The touch-sensitive layer is a completely separate device from the display part of the screen.

    If they are not aligned, the phone won't be able to tell exactly what displayed icon you meant to touch. Maybe it will be the one to the left, or below.

    "Calibration" is a procedure built in to the phone that lets you line up the touch-sensitive part of the screen with the image-displaying part of the screen.

    yes and yes to above, however it also calibrates the angle to which you press the section on the phone because you dont move the phone so that your always looking at it 100% perpendicular to the screen, there is variation and the calibtarion corrects that.

    all it really does is tell where the screens touch axis should be calibrated so that when you press on a key or such, it will be as precise as possible
