Display device and method of driving the same

A method of driving a display device comprising a display panel that is configured to an image, a sensing panel configured to at least partially overlap the display panel and that includes a sensing area and a non-sensing area, a sensing panel controller configured to drive the sensing panel, a plurality of sensing electrodes disposed in the sensing area, and a plurality of sensing lines electrically connected to the plurality of sensing electrodes, respectively, the method comprising:

• checking, by the sensing panel controller, an initial position where a capacitance change occurs on the sensing area;
• determining, by the sensing panel controller, whether the capacitance change occurs at a plurality of positions in the sensing area;
• checking, by the sensing panel controller, whether the capacitance change occurs at the same position as the initial position through division driving of the plurality of sensing electrodes;
• and
• recognizing, by the sensing panel controller, a final sensing coordinate in the sensing area,
• wherein the plurality of sensing lines are positioned to extend in one direction in the sensing area and the non-sensing area,
• wherein the sensing area includes a first sensing area, a second sensing area, and a third sensing area divided in a direction perpendicular to a direction in which the plurality of sensing lines are dense,
• wherein the plurality of sensing electrodes include first sensing electrodes, second sensing electrodes, and third sensing electrodes corresponding to the first sensing area, the second sensing area, and the third sensing area, and
• wherein when it is determined that the capacitance change occurs in the plurality of positions of the initial position, the sensing panel controller sequentially divides and drives the first sensing electrodes, the second sensing electrodes, and the third sensing electrodes.
