The embodiment of the invention provides a backlight brightness adjusting method, device and system and a storage medium. The adjusting method comprises the steps that the light mixing distance of the backlight module and the horizontal distance and the vertical distance between the multiple lamp panels are calculated; calculating a first brightness value according to the horizontal spacing and the light mixing distance, and calculating a second brightness value according to the vertical spacing and the light mixing distance; and adjusting the brightness of the spliced part of the plurality of lamp panels according to the first brightness value and/or the second brightness value. According to the scheme provided by the embodiment of the invention, the defect that dark fringes or bright fringes are generated at the splicing positions of the lamp panels can be overcome. 本公开实施例提供一种背光亮度的调整方法及设备和系统、存储介质。调整方法包括：计算背光模组的混光距以及多个灯板之间的水平间距和垂直间距；根据水平间距和混光距计算第一亮度值，根据垂直间距和混光距计算第二亮度值；根据第一亮度值和/或第二亮度值对多个灯板拼接处的亮度进行调整。本公开实施例提供的
