Abstract
(EN) A compensation method and compensation device for a display panel. The compensation method for the display panel comprises: obtaining and determining position information of a pixel under compensation of a panel under compensation according to an original image parameter of the panel at a target grayscale (S100); obtaining a first image parameter of the panel at a first reference grayscale and a second image parameter at a second reference grayscale (S200); determining a target compensation value of the pixel at the target grayscale according to the position information of the pixel, the first image parameter, and the second image parameter (S300); and determining the compensation brightness of the pixel at the target grayscale according to the target compensation value (S400).
(FR) L'invention concerne un procédé de compensation et un dispositif de compensation pour un panneau d'affichage. Le procédé de compensation pour le panneau d'affichage consiste à : obtenir et déterminer des informations de position d'un pixel subissant une compensation dans un panneau subissant une compensation, et ce en fonction d'un paramètre d'image d'origine du panneau à une échelle de gris cible (S100) ; obtenir un premier paramètre d'image du panneau à une première échelle de gris de référence et un second paramètre d'image à une seconde échelle de gris de référence (S200) ; déterminer une valeur de compensation cible du pixel à l'échelle de gris cible en fonction des informations de position du pixel, du premier paramètre d'image et du second paramètre d'image (S300) ; et déterminer la luminosité de compensation du pixel à l'échelle de gris cible en fonction de la valeur de compensation cible (S400).
(ZH) 一种显示面板的补偿方法及其补偿装置，该显示面板的补偿方法包括获取并根据待补偿面板在目标灰阶下的原始图像参数确定所述待补偿面板的待补偿像素的位置信息(S100)，获取待补偿面板在第一参考灰阶的第一图像参数以及在第二参考灰阶的第二图像参数(S200)；根据所述待补偿像素的位置信息、所述第一图像参数以及所述第二图像参数确定待补偿像素在目标灰阶下的目标补偿值(S300)；根据目标补偿值确定待补偿像素在目标灰阶下的补偿亮度(S400)。
