Abstract
(EN)
A compensation apparatus, a display screen, a display apparatus, and a compensation method, relating to the technical field of display. The compensation apparatus comprises a detection circuit (220) and a processor (240). The detection circuit (220) comprises a resistance sensitive member provided in a deformation area of a display screen. When the resistance sensitive member is deformed, the resistance of the resistance sensitive member changes. The detection circuit (220) is configured to detect a resistance change amount of the resistance sensitive member. The processor (240) is configured to obtain a drift amount of a characteristic curve of a drive transistor in the deformation area according to the resistance change amount, and adjusts, according to the drift amount, a drive voltage signal output to the drive transistor. The compensation apparatus can implement brightness compensation in the deformation area, so that light emitting in the deformation area becomes more uniform.

L’invention concerne un appareil de compensation, un écran d'affichage, un appareil d'affichage,, et un procédé de compensation, se rapportant au domaine technique de l'affichage. L'appareil de compensation comprend un circuit de détection (220) et un processeur. (240) Le circuit de détection (220) comprend un élément sensible à la résistance disposé dans une zone de déformation d'un écran d'affichage. Lorsque l'élément sensible à la résistance est déformé, la résistance de l'élément sensible à la résistance change. Le circuit de détection (220) est configuré pour détecter une ampleur de changement de résistance de l'élément sensible à la résistance. Le processeur (240) est configuré pour obtenir une quantité de dérive d'une courbe caractéristique d'un transistor d'attaque dans la zone de déformation en fonction de l'ampleur du changement de résistance et ajuste, en fonction de la quantité de dérive, un signal de tension d'attaque délivré au transistor d'attaque. L'appareil de compensation peut mettre en œuvre une compensation de luminosité dans la zone de déformation, de sorte que la lumière émise dans la zone de déformation devient plus uniforme.
