Abstract

Un élément électro-optique (ELD) est connecté entre un premier câblage d'alimentation (Vcom) et la seconde borne de conduction (D) d'un transistor de commande (21). La premiere borne de conductin (S) du transistor de commande (21) est connectée à un second câblage d'alimentation (Vp) ; et sa seconde borne de conduction (D) connectée à travers un premier transistor de commutation (22) à la borne de commande (G) du transistor de commande (21). La borne de commande (G) du premier transistor de commutation (22) est connectée à un câblage de commande (Wi). La borne de commande (G) du transistor de commande (21) est connectée par un premier condensateur (C1) à un nœud (K), qui est connecté par un second transistor de commutation (23) à une ligne de données (Sj). La borne de commande (G) du second transistor de commutation (23) est connectée à une ligne de balayage (Gi) ; et le nœud (K) est connecté à un troisième câblage de source d'alimentation (Vref) par un second condensateur (C2). La structure ainsi réalisée permet d'obtenir un circuit de pixels (Aij20) pour régler la période, pendant laquelle la tension de seuil du TFT d'entraînement (21) est compensée, librement, et pour réduire la consommation en puissance.
