Abstract:
1. A touch screen display device comprising: a touch screen display panel comprising: a readout unit which reads one of the touch data and the untouch data from each of the touch sensors and outputs the read data as sensing data corresponding to each of the sensing positions; and a sensing unit which groups the sensing positions into at least one pre-touch area using the sensing data and which recognizes at least one touch positions using the at least one pre-touch area, wherein at least one touch sensor provides touch data, wherein when a first sensing position and a third sensing position from among first through third sensing positions arranged sequentially in the second direction provide the touch data while the second sensing position provides the untouch data, the sensing unit recognizes the untouch data provided at the second sensing position as the touch data and groups the first through third sensing positions into a pre-touch area.
