Anti-noise signal modulation circuit, modulation method, display panel and display device

Abstract

An anti-noise signal modulation circuit, a modulation method, a display panel and a display device are disclosed. The anti-noise signal modulation circuit includes a frequency-modulation control sub-circuit. An input end of the frequency modulation control sub-circuit is configured to receive an initial signal, and an output end of the frequency-modulation control sub-circuit is connected to a signal processing circuit that is preset; the frequency-modulation control sub-circuit is configured to frequency-modulate the initial signal by a switch signal that hops according to a preset period, and to output a modulation result to the signal processing circuit; and a frequency corresponding to the switch signal does not overlap with a noise frequency.
