Abstract
(EN)
A method for adjusting display brightness and a related apparatus. The method is applicable to an electronic apparatus comprising a screen and a DPU. The DPU comprises N layer hardware units and a layer mixer. The N layer hardware units include a first layer hardware unit and M second layer hardware units, where N is an integer greater than 1, M is less than N, and each layer hardware unit is connected to the layer mixer. The method comprises: upon receiving an adjustment command with respect to backlight brightness of a screen, setting a backlight brightness value of the screen to be a first threshold; modifying a first layer to reduce brightness of the first layer; superimposing the modified first layer and multiple second layers to obtain a third layer; and displaying the third layer on the display screen. The invention can reduce screen flicking.

L'invention concerne un procédé d'ajustement de luminosité d'affichage et un appareil associé. Le procédé est applicable à un appareil électronique comprenant un écran et une DPU. La DPU comprend N unités matérielles de couche et un mélangeur de couches. Les N unités matérielles de couche comprennent une unité matérielle de première couche et M unités matérielles de deuxième couche, N étant un nombre entier supérieur à 1, M étant inférieur à N et chaque unité matérielle de couche étant connectée au mélangeur de couches. Le procédé comprend les étapes suivantes : lors de la réception d'une instruction d'ajustement par rapport à la luminosité de rétroéclairage d'un écran, régler une valeur de luminosité de rétroéclairage de l'écran à un premier seuil ; modifier une première couche pour réduire la luminosité de la première couche ; superposer la première couche modifiée et de multiples deuxièmes couches pour obtenir une troisième couche ; et afficher la troisième couche sur l'écran d'affichage. L'invention permet de réduire le sautillement de l'écran.
