摘要： A touch sensing apparatus is provided. The apparatus includes a flip-flop (15), a sensor (13), an AC signal (14), and a detector (16). The AC signal supplies AC signals to the flip-flop. The flip-flop outputs a first output signal at the output of flip-flop when the sensor is not touched. The sensor receives electricity signals from the object, and causes a delay of the AC signal inputted to the first input of the flip-flop, the delay of the AC signal to be inputted to the first input of the flip-flop further causes the flip-flop to output a second output signal at the output of the flip-flop. The detector detects a change from the first output signal to the second output signal at the output of the flip-flop and accordingly identifies a touch on the sensor.
