Title (EN) METHOD OF COMPENSATING MURA DEFECT OF DISPLAY PANEL, AND DISPLAY PANEL
(FR) PROCÉDÉ DE COMPENSATION DE DÉFAUT MURA D'UN PANNEAU D'AFFICHAGE, ET PANNEAU D'AFFICHAGE
(ZH) 一种显示面板的mura现象补偿方法及显示面板
Abstract:
(EN) A method of compensating a mura defect of a display panel comprises: performing compression on respective regions having n*m pixels, and storing a mura compensation value corresponding to a central pixel in each region, wherein the mura compensation value of the central pixel in at least one of the regions is an average mura compensation value of said region, and each of n and m is an integer greater than or equal to 2 (S110); and obtaining, according to the stored mura compensation value, mura compensation values corresponding to other pixels other than the central pixel in the same region (S120). Also disclosed is a display panel. The mura compensation method can reduce a required storage space.
(FR) Procédé de compensation d'un défaut Mura d'un panneau d'affichage consistant à : effectuer une compression sur des régions respectives ayant n*m pixels, et stocker une valeur de compensation Mura correspondant à un pixel central dans chaque région, la valeur de compensation Mura du pixel central dans au moins l'une des régions étant une valeur de compensation Mura moyenne de ladite région, et chacun des n et m est un nombre entier supérieur ou égal à 2 (S110) ; et obtenir, en fonction de la valeur de compensation Mura stockée, des valeurs de compensation Mura correspondant à d'autres pixels, autres que le pixel central dans la même région (S120). L’invention concerne également un panneau d’affichage. Le procédé de compensation d'effet Mura peut réduire un espace de stockage requis.
(ZH) 一种显示面板的mura现象补偿方法,包括以n*m像素的区域间隔做压缩,存储每个区域的中心像素对应的mura补偿值,其中,至少一个区域的中心像素的mura补偿值为相应区域的平均mura补偿值, n、m为大于或等于2的整数(S110);根据存储的mura补偿值获得同区域除中心像素之外的其他像素对应的mura补偿值(S120)。还公开了一种显示面板。该mura现象补偿方法具有节省存储空间的优点。
