Patent

CA 2692542

A display device is provided that includes: an unevenness correction information storage unit that stores unevenness correction information used to correct uneven light emission of the display unit; and an unevenness correction unit that corrects uneven light emission of the display unit by reading out the unevenness correction information from the unevenness correction information storage unit and by performing signal processing on the video signal having a linear characteristic. The unevenness correction unit corrects the uneven light emission of the display unit by combining a first correction that is applied in a horizontal direction or a vertical direction of the display unit, and a second correction that is applied to a section of the display unit in which uneven light emission is occurring.

L'invention porte sur un dispositif d'affichage qui comporte une section de stockage d'informations de correction de non-uniformité (164), qui stocke des informations de correction de non-uniformité pour corriger une non-uniformité de luminance d'une section d'affichage ; et une section de correction (130), qui corrige une non-uniformité de luminance de la section d'affichage par réalisation d'un traitement de signal sur un signal vidéo ayant des caractéristiques linéaires, par lecture d'informations de correction de non-uniformité à partir de la section de stockage d'informations de correction de non-uniformité (164). La section de correction de non-uniformité (130) corrige une non-uniformité d'émission de la section d'affichage par combinaison d'une première correction, à savoir, une correction dans la direction horizontale ou la direction verticale de la section d'affichage, et une deuxième correction, à savoir une correction d'une partie où une non-uniformité de luminance est générée sur la section d'affichage.
