(FR) DISPOSITIF DE COMMANDE DE LUMINOSITÉ DE RÉTROÉCLAIRAGE ET DISPOSITIF D'AFFICHAGE D'IMAGE
(ZH) 背光亮度控制装置、图像显示装置
Abstract:
(EN) A backlight brightness control device and an image display device (100), comprising an image processing unit (104), a master backlight controller (10311) which is connected to the image processing unit (104), a plurality of slave backlight controllers (10312) which are respectively connected to the master backlight controller (10311), and pulse width modulation (PWM) drivers (1032); the slave backlight controllers (10312) are used for controlling the backlight brightness of corresponding extension partitions; the extension partitions comprise one or more backlight partitions, and the extension partitions corresponding to each of the slave backlight controllers (10312) is different; and the slave backlight controllers (10312) are connected to one or more of the PWM drivers (1032).
(FR) L'invention concerne un dispositif de commande de luminosité de rétroéclairage et un dispositif d'affichage d'image (100), comprenant une unité de traitement d'image (104), un contrôleur de rétroéclairage maître (10311) qui est connecté à l'unité de traitement d'image (104), une pluralité de contrôleurs de rétroéclairage esclaves (10312) qui sont respectivement connectés au contrôleur de rétroéclairage maître (10311), et des pilotes de modulation de largeur d'impulsions (MLI) (1032). Les contrôleurs de rétroéclairage esclaves (10312) sont utilisés pour commander la luminosité de rétroéclairage de partitions d'extension correspondantes. Les partitions d'extension comprennent une ou plusieurs partitions de rétroéclairage et les partitions d'extension correspondant à chacun des contrôleurs de rétroéclairage esclaves (10312) sont différentes. Les contrôleurs de rétroéclairage esclaves (10312) sont connectés à un ou plusieurs pilotes PWM (1032).
(ZH) 一种背光亮度控制装置和图像显示装置(100),包括图像处理单元(104)、与所述图像处理单元(104)连接的主背光控制器(10311)、分别与所述主背光控制器(10311)连接的多个从背光控制器(10312)以及脉冲宽度调制PWM驱动器(1032);所述从背光控制器(10312)用于控制对应的扩展分区的背光亮度,所述扩展分区包括一个或多个背光分区,各所述从背光控制器(10312)对应的扩展分区不同;所述从背光控制器(10312)与一个或多个PWM驱动器(1032)连接。
