Abstract
A method includes acquiring a parameter value of a display screen to be adjusted; comparing the parameter value to a first set threshold and a second set threshold less than the first set threshold respectively. When the parameter value is equal to or greater than the first set threshold, perform dimming on the display screen, under a one-pulse condition, via both emission dimming mode and source dimming mode, or source dimming mode, to adjust the duty ratio of PWM to a first duty ratio. When the parameter value is less than the first set threshold, and is equal to or greater than the second set threshold, perform dimming on the display screen, under a multi-pulse condition, via both emission dimming mode and source dimming mode, or source dimming mode, to adjust the duty ratio of PWM to a second duty ratio less than the first duty ratio.
