Abstract

L'invention concerne un procédé et un système permettant d'établir des courants équilibrés à différents endroits dans des dispositifs nécessitant des sources de courant précises, adaptées et reproductibles, des dispositifs de visualisation comportant des réseaux de sources émettrices de lumière, par exemple. Dans un mode de réalisation, ce système et ce procédé permettent d'établir des courants étroitement équilibrés passant à travers des étages d'attaque de colonnes situés au niveau ou à proximité des parties d'extrémité d'une zone d'affichage. Ce procédé et ce système permettent d'obtenir des courants plus étroitement adaptés, au niveau de colonnes adjacentes, dans un dispositif tel qu'un dispositif de visualisation, les courants étant entraînés par des circuits d'attaque séparés, ce qui élimine la discontinuité de la luminance à travers la totalité de la zone d'affichage et permet d'obtenir des dispositifs de visualisation de qualité supérieure. D'autres modes de réalisation permettent d'établir des courants étroitement équilibrés passant à travers des étages d'attaque situés au niveau ou à proximité des parties d'extrémité d'une zone d'affichage. Le procédé et le système selon l'invention permettent également d'équilibrer des courants, au niveau de colonnes ou de zones adjacentes, sur l'ensemble du dispositif.
