A light-emitting panel and a brightness adjustment method, and a display device are provided. The method includes providing the light-emitting panel including a substrate, a plurality of light-emitting units, a control circuit, and a plurality of signal lines. The control circuit includes a data signal input terminal, a data storage unit, and a plurality of first signal terminals. The data storage unit is configured to store a first voltage signal and a first pulse width modulation signal corresponding to a different grayscale value. Each signal line connects a light-emitting unit with a first signal terminal. The method also includes obtaining a to-be-displayed screen, and determining each grayscale value of a corresponding light-emitting unit of the plurality of light-emitting units. Further, the method includes according to different grayscale values, calling the first pulse width modulation signal and the first voltage signal corresponding to each grayscale value in the data storage unit.
