Abstract

Panneau d'affichage à plasma et système de détection de parition du photosyle. Un signal composite est formé de 3 signaux composants : un échelon d'amplitude V, (V, = tension d'entretien), un échelon d'amplitude 2Vs et un échelon d'amplitude voisine de zéro. La détection des états sous tension et hors tension des cellules peut être détectée. Applicable aux dispositifs d'affichage, acquisition d'information projetée sur écran.
