VESA ajoute une nouvelle norme DisplayHDR True Black, cette fois adapt\u00e9e aux contraintes des \u00e9crans OLED. Au programme : des blancs moins lumineux, mais des noirs parfaits.<\/p>\n\n\n\n

Du HDR sur mesure<\/h3>\n\n\n\n

Les \u00e9crans OLED ne peuvent pas monter trop haut en luminosit\u00e9, notamment \u00e0 cause des normes de consommation \u00e9lectrique, mais aussi pour pr\u00e9server la long\u00e9vit\u00e9 des pixels OLED. Du coup, la norme True Black insiste sur des noirs tr\u00e8s profonds \u00e0 0,0005 cd\/m\u00b2, contre 0,05 cd\/m\u00b2 pour la norme DisplayHDR 1000. La luminosit\u00e9 est toutefois plus faible : 400 cd\/m\u00b2 pour le DisplayHDR 400 True Black et 500 cd\/m\u00b2 en\u00a0DisplayHDR 500 True Black. Des luminosit\u00e9 qui peuvent descendre \u00e0 250 et 300 cd\/m\u00b2 lorsque la totalit\u00e9 de la dalle affiche du blanc.
