Abstract
An input/output device is disclosed that includes a digitizer with an LCD mounted thereon and a protective layer mounted directly on the LCD to minimize the parallax errors that have heretofore occurred when a protective layer was mounted in a spaced relation from an LCD. The LCD is a fringe field switching (FFS) LCD which does not distort when pressure is applied to its upper surface through the directly connected protective layer.
