Abstract
(EN)
Disclosed is a spectrum spreading method, comprising the following steps: when a clock signal is detected, acquiring a modulation signal corresponding to the clock signal (S10); and performing spectrum spreading on the clock signal according to the modulation signal, wherein modulation signals corresponding to adjacent clock signals are inverted signals (S20). Further disclosed are a chip, a display panel and a computer-readable storage medium, solving the technical problem of a relatively poor spectrum spreading effect of a dual clock signal.
(FR)
L'invention concerne un procédé d'étalement de spectre consistant : lorsqu'un signal d'horloge est détecté, à acquérir un signal de modulation correspondant au signal d'horloge (S10) ; et à réaliser un étalement de spectre sur le signal d'horloge en fonction du signal de modulation, des signaux de modulation correspondant à des signaux d'horloge adjacents constituant des signaux inversés (S20). L'invention concerne en outre une puce, un panneau d'affichage et un support d’informations lisible par ordinateur, permettant de résoudre le problème technique d'un effet d'étalement de spectre relativement faible d'un signal d'horloge double.
