Title:
COMPENSATION APPARATUS, DISPLAY SCREEN, DISPLAY APPARATUS, AND COMPENSATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/114015
Kind Code:
A1
Abstract:
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.
