(ZH) 扫描信号生成方法及装置
Abstract
(EN)
A method and device (20) for generating scan signals (Gate1, Gate2, ...Gate8), the method comprising: acquiring an initial clock signal (CK0) (S101); processing the initial clock signal (CK0) so as to generate a plurality of target clock signals (CK1, CK2, CK3) (S102); according to a preset logical relationship, coding the plurality of target clock signals (CK1, CK2, CK3) so as to generate a plurality of ordered logic signals (S1, S2, ...S8) (S103); and decoding the plurality of ordered logic signals (S1, S2, ...S8), and generating a plurality of scan signals (Gate1, Gate2, ...Gate8) according to the decoding result (S104).
(FR)
L'invention concerne un procédé et un dispositif (20) pour générer des signaux de balayage (Gate1, Gate2, ... Gate8), le procédé comprenant les étapes consistant à : acquérir un signal d'horloge initial (CK0) (S101) ; traiter le signal d'horloge initial (CK0) de façon à générer une pluralité de signaux d'horloge cibles (CK1, CK2, CK3) (S102) ; selon une relation logique prédéfinie, coder la pluralité de signaux d'horloge cibles (CK1, CK2, CK3) de manière à générer une pluralité de signaux logiques ordonnés (S1, S2, ... S8) (S103) ; et décoder la pluralité de signaux logiques ordonnés (S1, S2, ... S8) et générer une pluralité de signaux de balayage (Gate1, Gate2, ... Gate8) en fonction du résultat de décodage (S104).
