METHOD FOR MODULATING BRIGHTNESS-GRAYSCALE CURVE OF DISPLAY DEVICE, AND ELECTRONIC DEVICE

A method for modulating a brightness-grayscale curve of a display device, and an electronic device. The method comprises: determining a human eye perception brightness-grayscale application standard curve (S711); obtaining a theoretical brightness value corresponding to each grayscale in a display device based on at least one of a factor of changes in the pupil of a human eye, an environmental factor and a factor related to a display device and the human eye perception brightness-grayscale application standard curve (S712); and modulating the brightness of the display device according to the theoretical brightness value corresponding to each grayscale in the display device (S713). The method solves the problems of unclear low-grayscale details, back-lighting of a picture, high-grayscale saturation, and unsmooth color transition, etc., and solves the problem that a visible grayscale in a dim link can no longer be distinguished in a bright environment, and proposes a quantitative modulation control standard.
