Abstract

L'invention concerne un circuit de pixel (21), un procédé d'attaque et un appareil d'affichage (1000). Le circuit de pixel (21) comprend un transistor d'attaque (T1), un sous-circuit d'écriture de données (201), un premier sous-circuit de compensation (202) et un second sous-circuit de compensation (205). Une première électrode du transistor d'attaque (T1) est connectée à un deuxième nœud (N2), une deuxième électrode de celui-ci est connectée à un troisième nœud (N3), une première électrode de commande de celui-ci est connectée à un premier nœud (N1), et une seconde électrode de commande de celui-ci est connectée à un quatrième nœud (N4) ; le sous-circuit d'écriture de données (201) est couplé au deuxième nœud (N2), à une première borne de signal de balayage (GATE1) et à une borne de signal de données (DATA) ; le premier sous-circuit de compensation (202) est couplé au premier nœud (N1), au troisième nœud (N3) et à une deuxième borne de signal de balayage (GATE2) ; le second sous-circuit de compensation (205) est couplé au premier nœud (N1), au quatrième nœud (N4) et à une troisième borne de signal de balayage (GATE3) ; et le second sous-circuit de compensation (205) est configuré pour commander la mise sous tension/hors tension du premier nœud (N1) et du quatrième nœud (N4) en réponse à la réception d'un troisième signal de balayage au niveau de la troisième borne de signal de balayage (GATE3).
