Claim:
1. A touch sensing display device comprising: a display panel; a capacitive touch panel disposed on a front surface of the display panel; a digitizer disposed on a surface of the display panel; a sensor driving unit which applies same scanning signals simultaneously to the capacitive touch panel and the digitizer; and a sensing unit which senses a sensing signal of the capacitive touch panel and a sensing signal of the digitizer, wherein the sensing unit receives the sensing signal of the capacitive touch panel and the sensing signal of the digitizer at different times, wherein each of the scanning signals is applied during a scanning signal application period, and a blank period is between two consecutive scanning signal application periods, wherein the sensing signal of the capacitive touch panel is transferred to the sensing unit during the scanning signal application period, and wherein the sensing signal of the digitizer is transferred to the sensing unit during the blank period.
