Abstract This display device is provided with: a BL control parameter calculation unit (224) that calculates BL control parameters from input images; a BL brightness control signal generation block (230) that generates BL brightness control signals from the BL control parameters; and an output unit (225) that outputs the BL control parameters calculated by the BL control parameter calculation unit (224) to the BL brightness control signal generation block (230) immediately before the start of an idle period in which a display control unit is idle. L'invention porte sur un dispositif d'affichage qui est pourvu : d'une unité de calcul de paramètres de commande BL (224) qui calcule des paramètres de commande BL à partir d'images d'entrée ; d'un bloc de génération de signaux de commande de luminosité BL (230) qui génère des signaux de commande de luminosité BL à partir des paramètres de commande BL ; d'une unité de sortie (225) qui fournit les paramètres de commande BL calculés par l'unité de calcul de paramètres de commande BL (224) au bloc de génération de signaux de commande de luminosité BL (230) immédiatement avant le début d'une période d'inactivité pendant laquelle une unité de commande d'affichage est inactive.
