Abstract:
(EN) The present invention provides a display apparatus and a control method thereof which re-calibrate an artifact of a display image recognized through a visual sensation even after execution of calibration, and thus can improve the brightness uniformity of multiple pixels and improve the chromaticity thereof. A display apparatus according to the disclosed one embodiment comprises: a display panel; a communication unit for receiving initial calibration coefficient values of a first pixel and at least one second pixel except the first pixel in the display panel; and a control unit for comparing a brightness of the first pixel with that of the second pixel on the basis of the initial calibration coefficient values, modifying the initial calibration coefficient values on the basis of a result of the comparison, and controlling the display panel on the basis of the modified initial calibration coefficient values.
(FR) La présente invention concerne un appareil d'affichage et son procédé de commande qui ré-étalonnent un artéfact d'une image d'affichage reconnue par une sensation visuelle même après l'exécution d'un étalonnage, et peuvent ainsi améliorer l'uniformité de luminosité de multiples pixels et améliorer leur chromaticité. Un appareil d'affichage selon le mode de réalisation décrit comprend : un panneau d'affichage ; une unité de communication pour recevoir des valeurs initiales de coefficient d'étalonnage d'un premier pixel et d'au moins un second pixel à l'exception du premier pixel dans le panneau d'affichage ; et une unité de commande pour comparer une luminosité du premier pixel à celle du second pixel sur la base des valeurs initiales de coefficient d'étalonnage, modifier les valeurs initiales de coefficient d'étalonnage sur la base d'un résultat de la comparaison, et commander le panneau d'affichage sur la base des valeurs initiales de coefficient d'étalonnage modifiées.
(KO) 보정(Calibration)이 이뤄진 후에도 시감각에 의해서 인지되는 디스플레이 영상의 아티팩트를 다시 보정함으로써, 복수의 픽셀 간 휘도의 균일도를 향상시키고, 색도를 향상시키는 디스플레이 장치 및 그 제어방법을 제공한다. 개시된 일 실시예에 따른 디스플레이 장치는 디스플레이 패널; 상기 디스플레이 패널의 제 1픽셀 및 상기 제 1픽셀을 제외한 적어도 하나의 제 2픽셀의 초기 보정 계수값을 수신하는 통신부; 상기 초기 보정 계수값에 기초하여 상기 제 1 픽셀과 상기 제 2픽셀의 휘도를 비교하고, 상기 비교 결과에 기초하여 상기 초기 보정 계수값을 수정하고, 상기 수정된 보정 계수값에 기초하여 상기 디스플레이 패널을 제어하는 제어부;를 포함한다.
