Abstract: A plasma display apparatus, and more particularly, a driving method and improved structure of a plasma display apparatus are provided. A sustain signal that alternates between a positive polarity and a negative polarity is supplied to only one electrode. Therefore, it can facilitate the adoption of an integrated driving board. Furthermore, a voltage magnitude of a set-up signal supplying in any one of the remaining sub-fields other than a first sub-field of a frame is less than the voltage magnitude of the set-up signal supplying in the first sub-field. It is therefore possible to increase the contrast.

Abstract: There are provided an image display apparatus having a display unit capable of sensing a touch made by a pointing device, and a method for operating the same. The method includes outputting a synchronous signal through the entire region of the display unit, transmitting a first scanning signal and a second scanning signal respectively scanning the display unit in a first direction and a second direction to the pointing device; and acquiring touch position information regarding a touch made by the pointing device by using touch time information regarding time points when the pointing device receives the first scanning signal and the second scanning signal after sensing the synchronous signal. Accordingly, an error in touch recognition caused by the delay of a synchronous signal can be minimized.
