An input/output device based on a plasma display technology uses a planar plasma panel construction to eliminate the spacer requirement, while making the upper viewing surface available for use as a digitizing tablet. Referring to the drawing, alternate conductors 12 separated by dielectric 14 function as drive lines from one axis of the display. A second set of orthogonal conductors (not shown) are positioned immediately above, but insulated from, conductors 12. A plurality of barrier electrodes 16 are positioned adjacent each conductor in both axes to prevent charge spreading in the drive lines.
