Abstract: front page image
(EN)A plurality of display pixels arranged in a matrix form respectively have a self-luminescent element (16), a driving transistor (22) which controls an electric current amount made to flow in the self-luminescent element, in accordance with an image signal, and a switch (24) formed of a thin-film transistor and connected between a gate and a drain of the driving transistor. The switch is controlled to be turned on and off by a control signal Sb supplied via a scanning line Cg from a scanning line driving circuit. When the switch is in an ON-state, an electric potential of the control signal is varied in a stepwise manner so as to be close to an electric potential for making the switch be in an OFF-state.
(FR)Selon cette invention, une pluralité de pixels d'affichage disposés selon une forme matricielle comprennent respectivement un élément auto-luminescent (16), un transistor de commande (22) chargé de commander une quantité de courant électrique qui circule dans l'élément auto-luminescent (16), conformément à un signal d'image, et un commutateur (24) comprenant un transistor en couches minces et connecté entre une grille et un drain du transistor de commande. Le commutateur peut être mis sous ou hors tension par un signal de commande (Sb) envoyé sur une ligne de balayage (Cg) par un circuit de commande de ligne de balayage. Lorsque le commutateur est sous tension, un potentiel électrique du signal de commande varie de manière séquentielle de façon qu'il soit proche d'un potentiel électrique entraînant la mise hors tension du commutateur.
