L'écran comporte: un dispositif de commande principal pour l'ajustement d'une taille d'affichage d'une image d'origine, de sorte que l'image d'origine dans l'écran d'affichage comprenne une zone d'affichage d'image et une zone de bordure noire située au niveau des côtés supérieur et inférieur de la zone d'affichage d'image, et la détermination d'une tension d'échelle de gris de chaque circuit de pixels (1031, 1032, 1033, 1034, 1035) dans la zone de bordure noire en fonction d'une tension de fonctionnement du circuit de pixels (1031, 1032, 1033, 1034, 1035) dans la zone d'affichage d'image dans l'écran d'affichage; un circuit d'attaque pour émettre en sortie la tension d'échelle de gris pour le circuit de pixels (1031, 1032, 1033, 1034, 1035) dans la zone de bordure noire; et le circuit de pixels (1031, 1032, 1033, 1034, 1035) pour un fonctionnement sous la tension d'échelle de gris, un dispositif d'émission de lumière (1035) dans le circuit de pixels (1031, 1032, 1033, 1034, 1035) n'émettant pas de lumière. Grâce à la tendance de cohérence entre une tension de fonctionnement d'un pixel dans une zone de bordure noire avec une tension de fonctionnement d'un pixel dans une zone d'affichage d'image, une vitesse de vieillissement de la zone de bordure noire et une vitesse de vieillissement de la zone d'affichage d'image ont tendance à être cohérentes, permettant d'améliorer la qualité d'affichage d'image.
