Abstract:
1. 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 (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.
