description The invention discloses a backlight control method and device of display equipment, a storage medium and an intelligent interaction panel. The display area of the display equipment is divided into a plurality of subareas, the backlight brightness of each subarea is independently controlled through a backlight driving device, and the method comprises the steps that a target subarea in the display equipment is obtained, and the target subarea is a subarea where a displayed image changes; obtaining a single adjustment amplitude, and determining that the backlight brightness adjustment frequency is an integral multiple of the image signal adjustment frequency of the display device; a dimming signal is sent according to the backlight brightness adjusting frequency so as to adjust the backlight brightness of the target partition, and the backlight brightness of the target partition is adjusted according to the single-time adjusting amplitude every time. The technical problem that in the prior art, flicker may occur
