Touch sensing display apparatus and driving method thereof

A driving method of a touch sensing display apparatus including a display panel including a plurality of pixels, and a touch screen panel disposed on the display panel and including first touch electrodes arranged in a first direction in which data lines extend and second touch electrodes arranged in a second direction intersecting the first direction, the driving method comprising:

• outputting data voltages, which are for driving the plurality of pixels, to data lines of the display panel;
• driving the first touch electrodes and the second touch electrodes to sense a touch input applied to touch sensors;
• and
• supplying a compensation voltage, which is for compensating for crosstalk caused by a variation of each of the data voltages, to first and second compensation electrodes respectively adjacent to the first and second touch electrodes while the touch input is being sensed, on the touch screen panel,
• wherein the compensation voltage and the data voltage vary with phases opposite to each other.

A touch sensing display apparatus comprising:

• a display panel including a plurality of pixels and a plurality of data lines;
• and
• a touch screen panel disposed on the display panel, the touch screen panel comprising:
• first touch electrodes disposed above the data lines and arranged in a first direction in which the data lines extend;
• second touch electrodes disposed above the data lines and arranged in a second direction intersecting the first direction;
• and
• first additional electrodes respectively adjacent to the first touch electrodes, and second additional electrodes respectively adjacent to the second touch electrodes.
