1. A display device comprising:

  • a plurality of sensor scanning lines extending in a first direction and sequentially receiving a first voltage;

    a plurality of sensor data lines extending in a second, different, direction;

    a plurality of sensing elements respectively formed in regions defined by the sensor scanning lines and the sensor data lines, and configured to transmit the first voltage from an associated sensor scanning line among the plurality of sensor scanning lines to an associated sensor data line among the plurality of sensor data lines according to an external touch;

    a sensing signal processor configured to convert voltages of the sensor data lines into sensing data; and

    a touch determining unit configured to determine positions of touch regions receiving external touches during at least one frame by processing sensing data for at least one sensor scanning line, wherein sensing data for at least one sensor scanning line is generated by sensing elements connected to one of the plurality of scanning lines.
