Title (EN) METHOD AND SYSTEM FOR DRIVING A PIXEL CIRCUIT IN AN ACTIVE MATRIX DISPLAY
(FR) PROCEDE ET SYSTEME DE COMMANDE D'UN CIRCUIT DE PIXELS DANS UN AFFICHAGE MATRICIEL ACTIF
Abstract:
(EN) A method and system for driving a pixel circuit in an active matrix display is provided. The system implements a feedback driving scheme to enhance programming speed of the pixel circuit. The system includes a column driver for driving the pixel circuit with feedback. A controller controls a signal on a programming signal line during a programming cycle. For example, the driver may include a model for reducing the settling time of a pixel current. During the programming mode, an accelerating pulse may be provided to accelerate the programming of the pixel circuit.
(FR) L'invention se rapporte à un procédé et à un système de commande d'un circuit de pixels dans un affichage matriciel actif. Le système permet de mettre en oeuvre un programme de commande de rétroaction pour améliorer la vitesse de programmation du circuit de pixels. Le système comprend un pilote de colonne conçu pour commander le circuit de pixels rétroactivement. Une unité de commande commande un signal sur une ligne de signal de programmation au cours d'un cycle de programmation. Par exemple, le pilote peut comprendre un modèle destiné à réduire le temps de réglage d'un courant en pixels. En mode de programmation, une impulsion d'accélération peut être générée pour accélérer la programmation du circuit de pixels.
