(57) Abstract:
(EN): Provided are a signal processing method, sequence control circuit, and system. The signal processing method comprises: receiving a data enable signal or monitoring an estimated data enable signal (200); according to the data enable signal or the estimated data enable signal, controlling the start timing of a shield signal (201). The present method eliminates overlap between frames, thus solving the problem of abnormal display caused by unwanted overlap of signals, and also enables full noise reduction of a GOA unit under normal input conditions, thereby extending the requirements for the service life of systems such as displays.
(FR): La présente invention concerne un procédé de traitement du signal et un système. Le procédé de traitement du signal consiste : à recevoir un signal d'activation de données ou à surveiller un signal d'activation de données estimé (200) ; selon le signal d'activation de données ou le signal d'activation de données estimé, à commander la synchronisation de démarrage d'un signal de protection (201). Le présent procédé élimine le chevauchement entre trames, résolvant ainsi le problème d'affichage anormal provoqué par un chevauchement indésirable des signaux et permet également la réduction complète du bruit d'une unité de GOA dans des conditions d'entrée normales, ce qui permet d'étendre les exigences pour la durée de vie de systèmes tels que des affichages.
(ZH): 一种信号处理方法、时序控制电路和系统。信号处理方法包括:接收数据使能信号或监测预估数据使能信号(200);根据数据使能信号或预估数据使能信号控制屏蔽信号的启动定时(201)。通过本方法可以消除帧与帧之间的重叠,从而解决了由于信号的不期望的重叠而导致的显示异常,还可以使得在正常输入的情况下能够对GOA单元进行充分的降噪,从而延长了诸如显示器等系统的使用寿命的要求。
