Patent Images

1. A touch screen plasma display comprising:

  • a Plasma Display Panel (PDP) adapted to display images by a gas discharge, and including a front substrate, front electrodes extending in a predetermined direction on a rear portion of the front substrate, a rear substrate facing the front substrate, rear electrodes extending in a direction of crossing the front electrodes on a front portion of the rear substrate, barrier ribs arranged between the front substrate and the rear substrate to define discharge spaces where the front and rear electrodes can be commonly disposed, phosphor layers arranged in the discharge spaces, and a discharge gas contained within the discharge spaces;

    an image displaying circuit unit adapted to supply driving control signals to the front electrodes and the rear electrodes to cause the PDP to display the images; and

    a position detecting circuit unit communicating with the image displaying circuit unit, and adapted to detect position information signals from the front and rear electrodes to generate induced currents by an electronic pen that changes a magnetic flux, to process the signals into a position coordinate signal of the electronic pen, and to transmit the position coordinate signal to the image displaying circuit unit.
