Disclosed are methods, apparatus, and storage media for dimming a display screen. The method includes: acquiring a parameter value of the display screen to be adjusted, wherein the parameter value has a correspondence with a brightness of the display screen; and comparing the parameter value with a set threshold to obtain a comparison result, and determining a corresponding dimming mode according to the comparison result, and performing dimming on the display screen via the corresponding dimming mode. The above method for dimming a display screen that determines a dimming mode according to a comparison result may overcome the deficiency caused by determining only one dimming mode, and may further mitigate impacts on the display quality while dimming.
