Abstract[English]
A method of operating a pixel driving circuit includes outputting driving currents in multiple cycles (CL1, CL2, CL3) in a frame of image to multiple light emitting elements(LE1, LE2, LE3), respectively. A respective light emitting element (LE1, LE2, LE3) of the multiple light emitting elements (LE1, LE2, LE3) is driven by driving currents output in a respective cycle (CL1, CL2, CL3) of the multiple cycles(CL1, CL2, CL3). The respective cycle (CL1, CL2, CL3) includes m number of periods (t1, t2...tm). Driving currents are output m number of times for m number of durations (1DU11, 1DU12...1DU1m...1DUnm), respectively, to the respective light emitting element (LE1, LE2, LE3) in the respective cycle (CL1, CL2, CL3) of the frame of image. In at least one frame of image, at least two durations (1DU11, 1DU12...1DU1m...1DUnm) of the m number of durations (1DU11, 1DU12...1DU1m...1DUnm) in the respective cycle (CL1, CL2, CL3) are different from each other.[French]
Un procédé de fonctionnement d'un circuit d'attaque de pixel consiste à délivrer des courants d'attaque dans de multiples cycles (CL1, CL2, CL3) dans une trame d'image à de multiples éléments électroluminescents (LE1, LE2, LE3), respectivement. Un élément électroluminescent respectif (LE1, LE2, LE3) des multiples éléments électroluminescents (LE1, LE2, LE3) est entraîné par des courants d'attaque produits dans un cycle respectif (CL1, CL2, CL3) des multiples cycles (CL1, CL2, CL3). Le cycle respectif (CL1, CL2, CL3) comprend un nombre m de périodes (t1, t2... tm). Des courants d'attaque sont délivrés m nombre de fois pendant un nombre m de durées (1DU11, 1DU12... 1 DU1m... 1 DUnm), respectivement, à l'élément électroluminescent respectif (LE1, LE2, LE3) dans le cycle respectif (CL1, CL2, CL3) de la trame d'image. Dans au moins une trame d'image, au moins deux durées (1DU11, 1DU12... 1 DU1m... 1 DUnm) du nombre m de durées (1DU11, 1DU12... 1 DU1m... 1 DUnm) dans le cycle respectif (CL1, CL2, CL3) sont différentes l'une de l'autre.
