Display device, driving method thereof, and electronic device

A driving method of a display device comprising a touch panel, wherein the driving method comprises:

• receiving position information of a pen adjacent to the touch panel;
• calculating a plurality of position coordinates of the pen;
• determining whether a drawing line connecting the plurality of position coordinates corresponds to a curved line based on the plurality of position coordinates of the pen;
• driving in a curved line mode when the drawing line corresponds to the curved line, or driving in a straight line mode when the drawing line does not correspond to the curved line;
• and
• changing a report rate value of the pen by considering a drawing speed of the pen in the curved line mode.

An electronic device comprising a display device, wherein the display device comprises:

• a touch panel comprising touch electrodes;
• and
• a touch driver configured to:
• receive position information of a pen adjacent to the touch panel;
• calculate a plurality of position coordinates of the pen;
• determine whether a drawing line connecting the plurality of position coordinates corresponds to a curved line based on the plurality of position coordinates of the pen;
• drive in a curved line mode when the drawing line corresponds to the curved line, or drive in a straight line mode when the drawing line does not correspond to the curved line;
• and
• change a report rate value of the touch panel by considering a drawing speed of the pen in the curved line mode.
