Abstract

La commande d'un écran à plasma matriciel comprend une sélection séquentielle de lignes de la matrice et pour une ligne sélectionnée, une désélection de plusieurs colonnes de la matrice précédemment sélectionnées lors de la sélection d'une ligne précédente. Afin d'éviter une raideur trop importante des fronts de descente des potentiels des colonnes, lesdites colonnes précédemment sélectionnées sont désélectionnées (33) de manière non simultanée.

Figure imgaf001
The control of a matrix plasma screen comprises a sequential selection of rows of the matrix and for a selected line, a deselection of several columns of the matrix previously selected during the selection of a previous line. In order to avoid too much stiffness of the falling edges of the column potentials, said previously selected columns are de-selected (33) non-simultaneously.
