Abstract
A driving method includes, at a first display brightness value, inputting a pulse-width modulation signal with a duty ratio of X, and controlling a light-emitting driving current of a sub-pixel unit to be M, wherein X and M are obtained according to a first modulation rule; and at a second display brightness value, inputting the pulse-width modulation signal with a duty ratio of Y1, and controlling the light-emitting driving current of the sub-pixel unit to be N1, wherein the first display brightness value is greater than the second one, wherein, when the duty ratio and the light-emitting driving current corresponding to the second display brightness value are obtained according to the first modulation rule, the duty ratio corresponding to the second display brightness value is Y2, the light-emitting driving current corresponding to the second display brightness value is N2, Y1 is smaller than Y2, and N1 is greater than N2.
