  • Patent number: 8860474
    Abstract: A control circuit for a sensing electrode array is described. The control circuit for the sensing electrode array includes a signal intensity analyzer, an intensity-to-phase frequency converter, and a phase frequency analyzing unit. The signal intensity analyzer obtains an intensity signal corresponding to a sensing signal of each sensing line of the sensing electrode array, wherein each intensity signal is a direct-current signal. The intensity-to-phase frequency converter generates a phase frequency signal based on the intensity signal. At least the phase or the frequency of the phase frequency signal is related to the level of the corresponding intensity signal. The phase frequency analyzing unit obtains a signal magnitude of the corresponding sensing line according to each phase frequency signal. The control circuit for the sensing electrode array enhances the operating speed and the signal-to-noise ratio of the touch control sensing system without increasing the manufacturing cost.
