1. A backlight module, comprising a plurality of backlight sources, wherein
the plurality of backlight sources each comprises a lamp panel and a plurality of light-emitting elements disposed on the lamp panel and electrically connected to the lamp panel,
the plurality of backlight sources each further comprises a transmission member, wherein the transmission member has one end directly fixedly connected to the lamp panel, the transmission member is configured to rotate so as to drive the lamp panel to rotate at a preset rotation rate, to make the lamp panel drive the plurality of light-emitting elements to rotate at the preset rotation rate, to form a surface light source, and
wherein the plurality of backlight sources are arranged in an array, a phase difference between two adjacent backlight sources is π/2, and an interval between rotation axes of two adjacent backlight sources is greater than a rotation radius of each of the plurality of backlight sources, and less than or equal to √2 times the rotation radius of each of the plurality of backlight sources, regions of surface light sources formed by rotation of two adjacent backlight sources being intersected.
