Abstract

Un dispositif d'affichage comprend un panneau d'affichage (14) comportant une pluralité de lignes de grille (16) et une pluralité de lignes de données (15) se croisant mutuellement et des pixels formés aux intersections de celles-ci ; un circuit de commande de grille (13) qui génère une impulsion de grille sur la base d'une tension de puissance de grille et applique l'impulsion de grille aux lignes de grille (16) ; un circuit de commande de données (12) qui divise la tension de puissance de données pour convertir des données vidéo numériques d'entrée en une tension de données analogique et qui applique la tension de données aux lignes de données (15); un circuit de commande de tension de puissance (111) qui détecte une fréquence de trame d'entrée et qui génère un signal de commande de puissance (CONT) différent en fonction de la fréquence de trame détectée ; et un circuit d'ajustement de tension de puissance (17) qui ajuste au moins l'une de la tension de puissance de grille et de la tension de puissance de données différemment d'un niveau de référence (VDD1/VGH1) prédéterminé en réponse au signal de commande de puissance.
