Title:
ANTI-NOISE SIGNAL MODULATION CIRCUIT, MODULATION METHOD, DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/010937
Kind Code:
A1
Abstract:
An anti-noise signal modulation circuit, a modulation method, a display panel, and a display device. The anti-noise signal modulation circuit comprises a frequency modulation control sub-circuit (102), an input end of the frequency modulation control sub-circuit being configured to receive an initial signal (101), while an output end of the frequency modulation control sub-circuit (102) is connected to a preset signal processing circuit (103); the frequency modulation control sub-circuit (102) is configured to perform frequency modulation on the initial signal (101) by means of a switch signal which jumps according to a preset period, and to output the modulation result to the signal processing circuit (103), the frequency corresponding to the switch signal not overlapping with the noise frequency.
