TOUCH SENSING APPARATUS AND OPERATING METHOD THEREOF
First Claim
1. A touch sensing apparatus, comprising:
- 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 plurality of first electrodes and detecting sensed signals from the plurality of 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 plurality of first electrodes during a first duration corresponding to a sleep mode and detect first sensed signals from the plurality of second electrodes, and determines whether a valid touch has occurred during the first duration to determine whether to cancel the sleep mode.
