Abstract
A driving circuit and an operating method thereof and a controlling circuit which are suitable for a knob apparatus are provided. The driving circuit includes multiple touch-sensing electrodes and a controlling circuit. The knob apparatus includes a knob and a touch panel. The knob is disposed on the touch panel. The touch-sensing electrodes and the controlling circuit are disposed in the touch panel. The touch-sensing electrodes are coupled to multiple pixel switches of the touch panel. The controlling circuit is coupled to the touch-sensing electrodes. During a touch period, the controlling circuit provides an offset voltage to a first touch-sensing electrode of the touch-sensing electrodes, such that a first pixel switch coupled to the first touch-sensing electrode maintains being turned off according to a touch-controlling signal and the offset voltage.
