Abstract
(EN) A method and apparatus for adjusting a dark-state view angle of a display panel, and an electronic device. The method comprises: acquiring a first brightness variation value, at a first voltage difference, for a panel to be tested (S10); acquiring a second brightness variation value, at the first voltage difference, for the panel to be tested (S20); acquiring a ratio of the second brightness variation value to the first brightness variation value (S30); and comparing the ratio of the second brightness variation value to the first brightness variation value with a first threshold, so as to determine whether the first voltage difference is a selected voltage for the display panel (S40).
(FR) La présente invention concerne un procédé et un appareil pour ajuster l'angle de vue à l'état sombre d'un panneau d'affichage, et un dispositif électronique. Le procédé consiste à: acquérir une première valeur de variation de luminosité, à une première différence de tension, pour un panneau à tester (S10); acquérir une seconde valeur de variation de luminosité, à la première différence de tension, pour le panneau à tester (S20); acquérir un rapport entre la seconde valeur de variation de luminosité et la première valeur de variation de luminosité (S30); et comparer le rapport entre la seconde valeur de variation de luminosité et la première valeur de variation de luminosité avec un premier seuil, de manière à déterminer si la première différence de tension est une tension sélectionnée pour le panneau d'affichage (S40)
(ZH) 一种显示面板的暗态视角的调整方法及装置、电子设备,包括:获取待测面板在第一电压差下的第一亮度变化值(S10);获取待测面板在第一电压差下的第二亮度变化值(S20);获取第二亮度变化值与第一亮度变化值的比值(S30);将第二亮度变化值与第一亮度变化值的比值与第一阈值进行对比,以判定第一电压差是否为显示面板的选择电压(S40)。
