Abstract
(EN)
Disclosed is a method for compensating uneven brightness of a display apparatus (700). The display apparatus (700) comprises a display screen (701), a data drive circuit (702) and a mainboard (703). The method for compensating uneven brightness comprises: the data drive circuit (702) obtaining first brightness compensation data from the mainboard (703) (S110); and then, the data drive circuit (702) adjusting image data according to the first brightness compensation data (S120).
(FR)
L’invention concerne un procédé permettant de compenser une luminosité irrégulière d'un appareil d'affichage (700). L'appareil d'affichage (700) comprend un panneau d'affichage (701), un circuit de commande de données (702) et une carte mère (703). Le procédé de compensation de luminosité irrégulière comprend les étapes suivantes : le circuit de commande de données (702) obtient des premières données de compensation de luminosité à partir de la carte mère (703) (S110) ; puis le circuit de commande de données (702) ajuste les données d'image en fonction des premières données de compensation de luminosité (S120).
(ZH)
一种用于显示装置(700)的亮度不均补偿的方法。显示装置(700)包括显示屏(701)、数据驱动电路(702)和主板(703)。亮度不均补偿方法包括:数据驱动电路(702)从主板(703)取得第一亮度补偿数据(S110),然后,数据驱动电路(702)根据该第一亮度补偿数据来调整图像数据(S120)。
