  • TOUCH PANEL CONTROLLER AND SENSING DEVICE INCLUDING THE SAME
    Publication number: 20230251746
    Abstract: A sensing device includes a touch panel including first and second sensor electrodes, and a touch panel controller acquiring a sensing signal from the touch panel and detecting a user input based on the sensing signal. The touch panel controller acquires the sensing signal from at least one of the first sensor electrodes and the second sensor electrodes in a first mode operating at a first power. The touch panel controller selects a first transmitting electrode, a second transmitting electrode, and receiving electrodes from one of the first sensor electrodes and the second sensor electrodes, inputs a first driving signal to the first transmitting electrode, and inputs a second driving signal having a phase difference of 180 degrees with respect to the first driving signal to the second transmitting electrode in a second mode operating at a second power and a third mode in which a sensing operation is performed.
