Patent ID: 8736637

Claim:
A chopper-stabilized signal generating method, comprising the steps of: (a) receiving a voltage polarity control signal; (b) sampling the voltage polarity control signal to obtain a sampling signal, and judging a manner of voltage transformation of the voltage polarity inversion of the voltage polarity control signal according to the sampling signal, the manner of voltage transformation indicating a specific voltage polarity inversion for driving a display panel; (c) obtaining a frame transformation signal template according to the manner of voltage transformation of the voltage polarity inversion of the voltage polarity control signal and the sampling signal, including judging whether the sampling signal is one of a plurality of sequence signals and counting the number of occurrences of the one of the sequence signals; and storing a specific one of the sequence signals as the frame transformation signal template when the number of occurrences of the specific one of the sequence signals is first counted to a predetermined number; (d) comparing the frame transformation signal template with the sampling signal to generate a frame transformation signal; and (e) generating a first chopper-stabilized signal according to the frame transformation signal and the voltage polarity control signal.
