In a touch sensing display device, a plurality of sensor scanning lines extend in a first direction and sequentially receive a first voltage, and a plurality of sensor data lines extend in a second, different, direction. A plurality of sensing elements are formed in regions defined by the sensor scanning lines and the sensor data lines, and each sensing element transmits the first voltage from a corresponding sensor scanning line to a corresponding sensor data line responsive to an external touch. A sensing signal processor converts voltages of the sensor data lines into sensing data, and, a touch determining unit processes the sensing data corresponding to the sensor scanning lines by at least one scanning line to determine positions of touch regions generated during at least one frame.
