Abstract[English]
A pixel driving circuit(PDC), a display apparatus and a display method are provided. The pixel driving circuit(PDC) includes a first circuit(C1) and a second circuit(C2). The first circuit(C1) is configured to provide a driving current to a light emitting element(LE) under control of the second circuit(C2). The second circuit(C2) is configured to receive a digital select signal from a digital select signal line(WL), a first digital data signal from a first digital data signal line(DLA), and a second digital data signal from a second digital data signal line(DLB); and control a frequency and duration by which the light emitting element(LE) receives the driving current during a frame of image, thereby controlling the grayscale of a subpixel having the light emitting element(LE).[French]
L'invention concerne un circuit d'excitation de pixel (PDC), un appareil d'affichage et un procédé d'affichage. Le circuit d'excitation de pixel (PDC) comprend un premier circuit (C1) et un second circuit (C2). Le premier circuit (C1) est conçu pour fournir un courant d'attaque à un élément électroluminescent (LE) sous la commande du second circuit (C2). Le second circuit (C2) est conçu pour recevoir un signal de sélection numérique en provenance d'une ligne de signal de sélection numérique (WL), un premier signal de données numérique en provenance d'une première ligne de signal de données numérique (DLA), et un second signal de données numérique en provenance d'une seconde ligne de signal de données numérique (DLB) ; et pour commander une fréquence et une durée de réception du courant d'attaque par l'élément électroluminescent (LE) pendant une trame d'image, ce qui permet de commander l'échelle de gris d'un sous-pixel doté de l'élément électroluminescent (LE).
