Abstract: A touch sensing display device includes: 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 sequentially applies scanning signals to the capacitive touch panel and the digitizer, where each of the scanning signal is applied simultaneously to the capacitive touch panel and the digitizer; and a sensing unit which senses sensing signals of the capacitive touch panel and the digitizer, in which the sensing unit receives the sensing signal of the capacitive touch panel and the sensing signal of the digitizer at different times.
