Title
(EN) METHODS AND CIRCUITS FOR DIODE-BASED DISPLAY BACKPLANES AND ELECTRONIC DISPLAYS
(FR) PROCÉDÉS ET CIRCUITS POUR DES PLANS ARRIÈRE D'AFFICHAGE À BASE DE DIODES ET DISPOSITIFS D'AFFICHAGE ÉLECTRONIQUES
Abstract
(EN)
An electronic display includes a plurality of pixels, each pixel including a data line, first and second selection lines and a common electrode. A control circuit element includes first and second diode-like elements coupled between the first and second selection lines and a charging node. A charging capacitive element is coupled between the charging node and the date line. An active pixel element is coupled between the charging node and the common electrode. The common electrode can overly the entire electronic display and is a suitable transparent conductive material. Each of the first and second diode-like elements includes an amorphous metal non-linear resistor. The active pixel element may include one of liquid crystal display circuitry, light emitting diode circuitry, and electrophoretic circuitry.

Selon la présente invention, un dispositif d'affichage électronique comprend une pluralité de pixels, chaque pixel comprenant une ligne de données, des première et seconde lignes de sélection et une électrode commune. Un élément de circuit de commande comprend des premier et second éléments de type diode couplés entre les première et seconde lignes de sélection et un nœud de charge. Un élément capacitif est couplé entre le nœud de charge et la ligne de date. Un élément de pixel actif est couplé entre le nœud de charge et l'électrode commune. L'électrode commune peut recouvrir l'ensemble du dispositif d'affichage électronique et est constituée d'un matériau conducteur transparent approprié. Chacun des premier et second éléments de type diode comprend une résistance non linéaire métallique amorphe. L'élément de pixel actif peut comprendre un élément parmi des circuits d'affichage à cristaux liquides, des circuits de diodes électroluminescentes et des circuits électrophorétiques.
