Abstract
(EN) Provided in the present disclosure are a display substrate, a fabrication method therefor, and a display apparatus. The display substrate comprises: a substrate and a plurality of sub-pixels distributed on the substrate, each sub-pixel comprising: a voltage stabilizing electrode, and a sub-pixel driving circuit. The sub-pixel driving circuits each comprise a driving transistor and a first transistor, a first electrode of the first transistor is coupled to a second electrode of the driving transistor, and a second electrode of the first transistor is coupled to a gate of the driving transistor. An active layer of the first transistor comprises a first semiconductor portion and second semiconductor portion that are arranged at an interval, as well as a conductor portion coupled to the first semiconductor portion and the second semiconductor portion, respectively. The orthographic projection of the conductor portion on the substrate overlaps with the orthographic projection of the voltage stabilizing electrode in the previous sub-pixel adjacent to the sub-pixel belonging thereto along a first direction on the substrate. The present disclosure can improve the uniformity of the brightness of sub-pixels of a display panel.
(FR) La présente invention concerne un substrat d'affichage, son procédé de préparation et un appareil d'affichage. Le substrat d'affichage comprend : un substrat et une pluralité de sous-pixels répartis sur le substrat et dont chacun comporte : une électrode de stabilisation de tension, et un circuit d'attaque de sous-pixel. Les circuits d'attaque de sous-pixels comprennent chacun un transistor d'attaque et un premier transistor, une première électrode du premier transistor est couplée à une seconde électrode du transistor d'attaque, et une seconde électrode du premier transistor est couplée à une grille du transistor d'attaque. Une couche active du premier transistor comprend une première partie semi-conductrice et une seconde partie semi-conductrice qui sont agencées à un intervalle, ainsi qu'une partie conductrice couplée à la première partie semi-conductrice et à la seconde partie semi-conductrice, respectivement. La projection orthographique de la partie conductrice sur le substrat chevauche la projection orthographique de l'électrode de stabilisation de tension dans le sous-pixel précédent adjacent au sous-pixel appartenant au substrat le long d'une première direction sur ce dernier. La présente invention permet d'améliorer l'uniformité de la luminosité de sous-pixels d'un panneau d'affichage.
