Abstract: A control system of a touch panel comprises a voltage controlled oscillator and a signal processing module. The voltage controlled oscillator is used for converting a direct current voltage signal that corresponds to a sensing signal of said touch panel into a sinusoidal signal. The signal processing module counts the frequency of the sinusoidal signal. The voltage controlled oscillator of the control system of touch panel converts direct current voltage signal into sinusoidal signal. Due to a wide change in the range of frequency of the sinusoidal signal that is outputted from the voltage controlled oscillator, the signal is not easily affected by noise, and thus, the signal-to-noise ratio of control system is comparatively higher. The present disclosure also provides a control method of touch panel.

Abstract: A control circuit for a sensing electrode array is described. The control circuit for the sensing electrode array includes a down-conversion circuit, an intensity-to-phase frequency converter, and a phase frequency analyzing unit. The down-conversion circuit down-converts a sensing signal of each sensing line of the sensing electrode array to obtain a corresponding down-converted signal. Each down-converted signal is substantially a direct-current signal. The intensity-to-phase frequency converter generates a corresponding phase frequency signal for each down-converted signal. At least the phase or the frequency of the phase frequency signal is related to the level of the corresponding down-converted signal. The phase frequency analyzing unit obtains signal magnitude of the corresponding sensing lines based on the phase frequency signal. Therefore, the control circuit for the sensing electrode array enhances operating speed and signal-to-noise ratio of the touch control sensing system without increasing the manufacturing cost.
