Abrégé
(EN) A display device according to one embodiment described in the present specification comprises: a display panel having a plurality of pixels; a timing controller for receiving a compensation command signal within a vertical blank section in which image data is not written by the pixels; and a sensing circuit for sensing driving characteristics of the pixels in one or more sensing sections corresponding to the compensation command signal. The length of the vertical blank section is different in a first frame and a second frame, and the number of the sensing sections having a predetermined length varies according to the length of the vertical blank section.
(FR) Un dispositif d'affichage selon un mode de réalisation décrit dans la présente invention comprend : un panneau d'affichage ayant une pluralité de pixels ; un contrôleur de synchronisation permettant de recevoir un signal de commande de compensation à l'intérieur d'une section de découpe verticale dans laquelle des données d'image ne sont pas écrites par les pixels ; et un circuit de détection permettant détecter des caractéristiques de commande des pixels dans une ou plusieurs sections de détection correspondant au signal de commande de compensation. La longueur de la section de découpe verticale est différente dans une première trame et une seconde trame, et le nombre des sections de détection ayant une longueur prédéterminée varie en fonction de la longueur de la section de découpe verticale.
(KO) 본 명세서의 실시예에 따른 표시장치는, 복수의 픽셀이 구비된 표시패널; 상기 픽셀로 영상 데이터가 기입되지 않는 수직 블랭크 구간 내에서 보상 커맨드 신호를 입력 받는 타이밍 콘트롤러; 및 상기 보상 커맨드 신호에 대응되는 적어도 하나 이상의 센싱 구간에서 상기 픽셀의 구동 특성을 센싱하는 센싱 회로를 포함하고, 상기 수직 블랭크 구간의 길이가 제1 프레임과 제2 프레임에서 서로 다르고, 일정 길이를 갖는 상기 센싱 구간의 개수가 상기 수직 블랭크 구간의 길이에 따라 달라진다.
