Display device and driving method for display device using the same

A driving method of a display device, the driving method comprising:

• sensing a grip by a sensor unit in response to touching of a first gripping sensor;
• detecting a position of a first sensing input signal line corresponding to the first touched gripping sensor;
• generating a gripping signal comprising touch information of the first touched gripping sensor and position information of the first sensing input signal line corresponding to the first touched gripping sensor;
• controlling a sensing scan control signal such that a first sensing input signal having a higher voltage than a predetermined reference voltage is applied to the first sensing input signal line corresponding to the first touched gripping sensor, while applying a second sensing input signal different from the first sensing input signal to a sensing input signal line that does not correspond to the first touched gripping sensor, according to the position information of the sensing input signal line corresponding to the first touched gripping sensor;
• and
• generating a sensing input signal applied to the first sensing input signal line according to the sensing scan control signal,
• wherein the display device comprises:
• a display unit comprising sensing input signal lines, sensing output signal lines, and touch sensors formed of the sensing input signal lines and the sensing output signal lines;
• a sensing scan driver;
• the sensor unit comprising gripping sensors corresponding to the sensing input signal lines;
• and
• a signal controller configured to generate the sensing scan control signal.
