Abstract

L'invention concerne un dispositif électronique. Le dispositif électronique peut comprendre un capteur d'éclairement, un dispositif d'affichage comprenant des sous-pixels, et un processeur. Le processeur peut être configuré pour : acquérir des données indiquant le niveau d'éclairement autour du dispositif électronique au moyen du capteur d'éclairement pendant qu'un écran est affiché sur le dispositif d'affichage selon une première fréquence d'attaque ; lorsque les données indiquent un éclairement supérieur à un éclairement de référence, modifier la fréquence d'attaque pour l'émission de lumière des sous-pixels pour la faire passer à une seconde fréquence d'attaque qui est supérieure à la première fréquence d'attaque, affichant ainsi l'écran sur le dispositif d'affichage selon la seconde fréquence d'attaque ; lorsque les données indiquent un éclairement inférieur à l'éclairement de référence, identifier si la valeur indiquant un courant appliqué à au moins certains des sous-pixels est inférieure à une valeur de référence ; et, lorsque la valeur est inférieure à la valeur de référence, modifier la fréquence d'attaque pour la faire passer à la seconde fréquence d'attaque, affichant ainsi l'écran sur le dispositif d'affichage selon la seconde fréquence d'attaque.
