  • Publication number: 20200226976
    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.

  • Publication number: 20200126488
    Abstract: A flexible display panel and a flexible display device are described. The flexible display panel includes a bending region, a non-bending region. A number of deformation detection units are disposed in the bending region. The deformation detection units each includes a first electrode, a piezoelectric (PZT) material function layer and a second electrode which are sequentially stacked in a direction perpendicular to a light-emitting surface of the flexible display panel. The density of the PZT units and PZT function layer thickness may vary depending on their distance from the bending axis.
