CA 2463486

A display device includes a plurality of scanning lines (X1 - X m), a plurality of signal lines (Y1 - Y n), a scanning driver (5) which sequentially supplies to the scanning lines selection signals that select the scanning lines, a data driver (3) which supplies a designation current to the plurality of signal lines within a selection period when the scanning lines are being selected, a plurality of pixel circuits which supplies a driving current corresponding to a current value of the designation current that flows to the signal lines, a plurality of optical elements (E1,1 - E m,n) which emit light in accordance with the driving current supplied by the plurality of pixel circuits and a power supply (6) which outputs to the plurality of pixel circuits a driving current reference voltage to supply the driving current.

La présent invention a trait à un dispositif comportant une pluralité de lignes de lignes d'analyse (X1 - Xm), une pluralité de lignes de signal (Y1 - Yn), une commande de balayage (5) fournissant séquentiellement aux lignes d'analyse des signaux de sélection qui effectuent la sélection de lignes d'analyse, une commande de données (3) fournissant un courant de désignation à la pluralité de lignes de signal au cours d'une période de sélection lors de la sélection des lignes d'analyse, une pluralité de circuits de pixels fournissant une courant d'excitation correspondant à la valeur courante du courant de désignation qui circule vers les lignes de signal, une pluralité d'éléments optiques (E1, 1-Em,n) émettant de la lumière selon le courant d'excitation fourni par la pluralité de circuits de pixels et une alimentation (6) fournissant à la pluralité de circuits de pixels une tension de référence de courant d'excitation en vue de la fourniture du courant d'excitation.
