Abstract:
(EN) Disclosed are a signal generation circuit (10) and a signal generation method, a light-emitting apparatus drive circuit (80) and a display apparatus. The signal generation circuit (10) comprises: a control circuit (12) configured to compute at least one of frequency control word information (F) and duty ratio control word information (D) according to an instruction; and a pulse width modulation circuit (14) configured to generate a pulse signal according to at least one of the frequency control word information (F) and the duty ratio control word information (D).
(FR) L'invention concerne un circuit de génération de signal (10) et un procédé de génération de signal, un circuit d'attaque d'appareil électroluminescent (80) et un appareil d'affichage. Le circuit de génération de signal (10) comprend : un circuit de commande (12) conçu pour calculer des informations de mot de commande de fréquence (F) et/ou des informations de mot de commande de facteur de marche (D) selon une instruction ; et un circuit de modulation de largeur d'impulsion (14) conçu pour générer un signal d'impulsion en fonction des informations de mot de commande de fréquence (F) et/ou des informations de mot de commande de facteur de marche (D).
(ZH) 一种信号生成电路(10)及信号生成方法、发光装置驱动电路(80)及显示装置。所述信号生成电路(10)包括:控制电路(12),被配置为根据指令计算频率控制字信息(F)或占空比控制字信息(D)中的至少之一;以及脉冲宽度调节电路(14),被配置为根据所述频率控制字信息(F)和所述占空比控制字信息(D)中的至少之一生成脉冲信号。
