Abstract
Disclosed is a method for spreading spectrum, which includes: acquiring a modulation signal corresponding to a clock signal, when the clock signal is detected; and spectrum spreading the clock signal according to the modulation signal, wherein the modulation signals respectively corresponding to two adjacent clock signals are opposite in phase. The present disclosure further provides a chip, a display panel, and a computer readable storage medium. The present disclosure solves the technical problem of poor spread spectrum effect on dual clock signals.
