Abstract

Au moins l'un des deux plans conducteurs rectangulaires, P1, pr?vus pour appliquer une tension aux bornes de chacun des pixels d'une matrice, est aliment? par deux bords adjacents b3, b4 ? partir de sources de tension individuelles s ? s , S ? s r?parties le long de chacun des bords. Les sources de tension ont des valeurs de tension diff?rentes, variant de pr?f?rence mais pas obligatoirement de mani?re monotone croissante entre une valeur inf?rieure v , v du c?t? de la jonction J entre les deux bords b3 et b4 et une valeur sup?rieure v , v de l'autre c?t? de chacun des bords. Les deux bords b3 et b4 par lesquels le plan conducteur est principalement aliment? sont d?coup?s pour former des points de contact ?lectrique localement isol?s les uns des autres et r?guli?rement espac?s, aliment?s chacun par une source de tension individuelle respective. L'autre plan conducteur peut ?tre aliment? de la m?me mani?re.
