Title: Touch sensing apparatus and operating method thereof

Abstract: There are provided a touch sensing apparatus and an operating method thereof. The touch sensing apparatus includes: a panel unit including a plurality of first electrodes and a plurality of second electrodes, the first and second electrodes intersecting each other; a circuit unit applying first driving signals to the first electrodes and detecting sensed signals from the second electrodes; and a control unit controlling an operation of the circuit unit, wherein the control unit controls the circuit unit to simultaneously apply the first driving signals to the first electrodes during a first duration corresponding to a sleep mode and detect first sensed signals from the second electrodes, and determines whether a valid touch has occurred during the first duration to determine whether to cancel the sleep mode.
