  • Publication number: 20120293452
    Abstract: An exemplary operating method of a capacitive touch panel adapted to a touch control barrier-type three-dimensional display device and including a sensing device is disclosed. In the operating method, a sensing voltage readout operation is performed only during a signal caused by a transient of a barrier voltage is smaller than a preset value. The voltage readout operation includes steps of: providing a first driving signal to the sensing device for performing the sensing voltage readout operation during the barrier voltage is at a logic high level; and providing a second driving signal to the sensing device for performing the sensing voltage readout operation during the barrier voltage is at a logic low level. A pulse amplitude of the first driving signal is smaller than that of the second driving signal.
