Abstract
(EN) A control circuit, a display apparatus, and a method for supplying power to a light source in the display apparatus. The control circuit comprises a first power source (1), a second power source (2) and a control module (3). The first power source (1) and the second power source (2) are both connected to the control module (3). The control module (3) is used for controlling the connection between the first power source (1) and a light source (4) and the connection between the second power source (2) and the light source (4).
(FR) L'invention concerne un circuit de commande, un appareil d'affichage et un procédé de fourniture d'énergie à une source de lumière dans l'appareil d'affichage. Le circuit de commande comprend une première source d'énergie (1), une deuxième source d'énergie (2) et un module de commande (3). La première source d'énergie (1) et la deuxième source d'énergie (2) sont toutes deux connectées au module de commande (3). Le module de commande (3) est utilisé pour commander la connexion entre la première source d'énergie (1) et une source de lumière (4) et la connexion entre la deuxième source d'énergie (2) et la source de lumière (4).
(ZH) 一种控制电路、显示装置及用于向显示装置中的光源供电的方法。控制电路包括第一电源(1)、第二电源(2)和控制模块(3)。第一电源(1)和第二电源(2)均与控制模块(3)连接。控制模块(3)用于控制第一电源(1)与光源(4)之间的连接以及第二电源(2)与光源(4)之间的连接。
