Abstract
(EN) A display apparatus is disclosed. The display apparatus comprises: a display panel; a backlight unit comprising a plurality of backlight blocks; and a processor which drives the backlight unit to provide light to the display panel. The processor may: adjust an image with a first resolution to provide an image with a second resolution smaller than the first resolution; divide an image area of the image with the second resolution, which corresponds to a first backlight block among the plurality of backlight blocks, into a plurality of image regions; acquire current information corresponding to the first backlight block and a second backlight block adjacent to the first backlight block on the basis of the plurality of image regions; and drive the backlight unit on the basis of the acquired current information.
(FR) Un appareil d'affichage est divulgué. L'appareil d'affichage comprend : un écran d'affichage ; une unité de rétroéclairage comprenant une pluralité de blocs de rétroéclairage ; et un processeur qui entraîne l'unité de rétroéclairage pour fournir de la lumière à l'écran d'affichage. Le processeur peut : ajuster une image avec une première résolution pour fournir une image ayant une seconde résolution plus faible que la première résolution ; diviser une zone d'image de l'image avec la seconde résolution, qui correspond à un premier bloc de rétroéclairage parmi la pluralité de blocs de rétroéclairage, en une pluralité de régions d'image ; acquérir des informations de courant correspondant au premier bloc de rétroéclairage et un second bloc de rétroéclairage adjacent au premier bloc de rétroéclairage sur la base de la pluralité de régions d'image ; et entraîner l'unité de rétroéclairage sur la base des informations de courant acquises.
(KO) 디스플레이 장치가 개시된다. 디스플레이 장치는, 디스플레이 패널, 복수의 백라이트 블럭을 포함하는 백라이트 유닛 및 디스플레이 패널로 광을 제공하도록 백라이트 유닛을 구동하는 프로세서를 포함한다. 여기서, 프로세서는, 제1 해상도의 영상을 제1 해상도보다 작은 제2 해상도의 영상으로 조정하고, 제2 해상도 영상에서 복수의 백라이트 블럭 중 제1 백라이트 블럭에 대응되는 영상 영역을 복수의 영상 영역으로 분할하고, 복수의 영상 영역에 기초하여 제1 백라이트 블럭 및 제1 백라이트 블럭에 인접한 제2 백라이트 블럭에 대응되는 전류 정보를 획득하고, 획득된 전류 정보에 기초하여 백라이트 유닛을 구동할 수 있다.
