Abstract[English]
A light emitting substrate is provided. The light emitting substrate includes a plurality of subpixels. A respective subpixel of the plurality of subpixels includes n1 number of main light emitting elements; n1 number of main pixel driving circuits configured to drive light emission in the n1 number of main light emitting elements; n2 number of auxiliary light emitting elements; n2 number of auxiliary pixel driving circuits configured to drive light emission in the n2 number of auxiliary light emitting elements; n1 ≥ 1, and n2 ≥ 1. A respective main pixel driving circuit of the n1 number of main pixel driving circuits includes a first driving transistor(Td). A respective auxiliary pixel driving circuit of the n2 number of auxiliary pixel driving circuits includes a second driving transistor(Td'). Threshold voltage levels of the first driving transistor(Td) and the second driving transistor(Td') are substantially the same.[French]
L'invention concerne un substrat électroluminescent. Le substrat électroluminescent comprend une pluralité de sous-pixels. Un sous-pixel respectif de la pluralité de sous-pixels comprend un nombre n1 d'éléments électroluminescents principaux ; un nombre n1 de circuits d'attaque de pixel principaux configurés pour entraîner l'émission de lumière dans le nombre n1 d'éléments électroluminescents principaux ; un nombre n2 d'éléments électroluminescents auxiliaires ; un nombre n2 de circuits d'attaque de pixel auxiliaires configurés pour entraîner l'émission de lumière dans le nombre n2 d'éléments électroluminescents auxiliaires ; n1 ≥ 1, et n2 ≥ 1. Un circuit d'attaque de pixel principal respectif du nombre n1 de circuits d'attaque de pixel principaux comprend un premier transistor d'attaque (Td). Un circuit d'attaque de pixel auxiliaire respectif du nombre n2 de circuits d'attaque de pixel auxiliaires comprend un second transistor d'attaque (Td'). Les niveaux de tension de seuil du premier transistor d'attaque (Td) et du second transistor d'attaque (Td') sont sensiblement identiques.
