Abstract
(EN)
A method and apparatus (30) for adjusting the brightness of a display panel (10), the method comprising: dividing a display region into a plurality of compensation regions (11); acquiring the difference between an initial brightness value of each compensation region (11) and a preset reference brightness value; according to the difference of a compensation region (11), adjusting the current of an organic light-emitting diode (D10) of a sub-pixel in the corresponding compensation region (11) so as to obtain an adjusted current; and according to the adjusted current, compensating the initial brightness value of the corresponding compensation region (11) so as to obtain a target brightness value.
(FR)
L’invention concerne un procédé et un appareil (30) permettant d’ajuster la luminosité d'un panneau d'affichage (10), ledit procédé consistant à : diviser une zone d'affichage en une pluralité de zones de compensation (11 ) ; acquérir la différence entre une valeur de luminosité initiale de chaque zone de compensation (11) et une valeur de luminosité de référence prédéfinie ; en fonction de la différence d'une zone de compensation (11), ajuster le courant d'une diode électroluminescente organique (D10) d'un sous-pixel dans la zone de compensation correspondante (11) de façon à obtenir un courant ajusté ; et en fonction du courant ajusté, compenser la valeur de luminosité initiale de la zone de compensation correspondante (11) de façon à obtenir une valeur de luminosité cible.
(ZH)
一种显示面板(10)的亮度调整方法及装置(30),方法包括:将显示区域划分为多个补偿区域(11);获取每个补偿区域(11)的初始亮度值与预设参考亮度值之间的差值;根据补偿区域(11)的差值调整对应补偿区域(11)中子像素的有机发光二极管(D10)的电流,得到调整电流;根据调整电流对对应补偿区域(11)的初始亮度值进行补偿,得到目标亮度值。
