Abstract

Provided is a display brightness compensation method including: setting an aging grayscale of a monochrome pixel of each of n test display panels; setting m test grayscales of the monochrome pixel; during a time period, illuminating the aging grayscale of the monochrome pixel, periodically illuminating each test grayscale of the monochrome pixel, and periodically obtaining a test display brightness of the monochrome pixel at the test grayscale at the aging grayscale; calculating a brightness-time characteristic of the monochrome pixel at each of the m test grayscales at the aging grayscale; and compensating an actual display brightness of a monochrome pixel of a target display panel at a current display moment based on the brightness-time characteristic. Both m and n are positive integers greater than or equal to 2. The monochrome pixels of any two test display panels have different aging grayscales.
