Title (EN) HIGH SPEED IMAGE CALIBRATION-ENABLED LED ELECTRONIC DISPLAY BOARD
(FR) PANNEAU D'AFFICHAGE ÉLECTRONIQUE À DEL ACTIVÉ PAR ÉTALONNAGE D'IMAGE À GRANDE VITESSE
(KO) 하이 스피드 영상 컬리브레이션이 가능한 LED 전광판
Abstract:
(EN) The present invention relates to a high speed image calibration-enabled LED electronic display board in which, through a pixel capacitor controller device provided between an image input device and a main controller, it is checked for inputted image information whether a brightness value difference exists in a part of pixels or displayed portions of the LED electronic display board, and image data being inputted in real time is corrected by applying luminance correction data according to luminance characteristics, so as to display image data in which the luminance is corrected, thereby enabling luminance correction of the image in the electronic display board regardless of a configuration of an electronic display board display driving circuit.
(FR) La présente invention concerne un tableau d'affichage électronique à DEL activé par étalonnage d'image à grande vitesse dans laquelle, par l'intermédiaire d'un contrôleur de condensateur de pixel situé entre un dispositif d'entrée d'image et un contrôleur principal, on vérifie, en ce qui concerne des informations d'image entrées, si une différence de valeur de luminosité existe dans une partie de pixels ou des parties affichées du tableau d'affichage électronique à DEL, et des données d'image entrées en temps réel sont corrigées par l'application de données de correction de luminance en fonction de caractéristiques de luminance, de façon à afficher des données d'image dans lesquelles la luminance est corrigée, ce qui permet une correction de luminance de l'image dans le tableau d'affichage électronique indépendamment d'une configuration d'un circuit d'attaque d'affichage de tableau d'affichage électronique.
(KO) 본 발명은 영상입력장치와 메인컨트롤러 사이에 설치된 픽셀 캐패시터 컨트롤러 장치를 통해 입력된 영상정보에 대해 LED 전광판의 픽셀 또는 표출부분의 일부에서 밝기값의 상이 여부를 확인하여 휘도특성에 따라 휘도보정 데이터를 적용하여 실시간으로 입력되는 영상데이터를 보정하여 휘도가 보정된 영상데이터를 표출함으로써 전광판 표출 구동회로의 구성에 관계없이 전광판의 영상 휘도 보정이 가능한 하이 스피드 영상 컬리브레이션이 가능한 LED 전광판에 관한 것이다.
