Claim 15:
16. A method of driving an input sensing unit, the input sensing unit including a touch sensing unit which includes a plurality of driving electrodes and a plurality of sensing electrodes insulated from and intersecting the plurality of driving electrodes, and a driving signal generating unit which provides driving signals to the plurality of driving electrodes, the method comprising:
providing, by a digital-to-analog converter, a first signal or a second signal;
generating, by an ath switch unit, the driving signals by using the first signal or the second signal;
providing, by a bth switch unit, the driving signals to the plurality of driving electrodes; and
detecting, by a sensing unit, a change in capacitance of a capacitor between the driving electrode to which the driving signal is applied and an electrode corresponding thereto,
wherein the driving signal generating unit includes touch drivers connected to the digital-to-analog converter and the plurality of driving electrodes, and wherein each touch driver is connected to a preset number of driving electrodes constituting a block of driving electrodes among the plurality of driving electrodes, and
wherein the providing of the driving signals to the plurality of driving electrodes includes sequentially providing the driving signals to the driving electrodes in a block, and concurrently providing the driving signals to the driving electrodes having a same ordinal position in each block.
