Abstract

La présente invention concerne un procédé de commande d'affichage utilisé dans un écran d'affichage, et un produit associé. Le procédé de commande d'affichage consiste à : obtenir une luminosité actuelle d'un écran d'affichage ; déterminer, selon une correspondance préconfigurée, des informations de réglage d'une couleur cible correspondant à la luminosité actuelle ; réaliser, selon les informations de réglage déterminées, un réglage de réduction correspondant sur la couleur cible dans le contenu à afficher ; et délivrer, à l'écran d'affichage, le contenu réglé à afficher de sorte à l'afficher. La solution technique est utilisée pour réaliser, selon la luminosité actuelle de l'écran d'affichage, et sur la couleur cible dans le contenu à afficher, un processus de réduction de couleur correspondant, ce qui réduit une composante de couleur cible dans le contenu à afficher et résout le problème de biais de couleur d'un écran d'affichage sans augmenter les coûts matériels.
