摘要
The touch sensing apparatus includes a driving unit and a touch sensing unit, a scan region selecting unit, and a control unit. The driving unit and the touch sensing unit arranged at a touch panel are electrically connected to driving electrodes and sensing electrodes, respectively. The scan region selecting unit controls the driving unit and determines a narrowed scan region including a touched location by dividing a touch region of the touch panel into a plurality of scan regions, scanning each of the scan regions, and selecting a scan region including the touched location at least for once. The control unit controls the scan region selecting unit and the driving unit and determines the narrowed scan region including the touched location and sense the touched location by inputting signals in a time-division manner to a plurality of scan lines included in the narrowed scan region.
