Backlight source, display device, and method for partition control

A display device, comprising:

• a backlight module, configured to provide light for display and comprising an optical regulating assembly, a back panel, a driving assembly, and a plurality of backlight sources, wherein
• the plurality of backlight sources are disposed on the back panel and each comprises a lamp panel, a plurality of light-emitting elements disposed on the lamp panel and electrically connected to the lamp panel, and 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 √{square root over (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;
• the optical regulating assembly is disposed at a light-exiting side of the backlight sources of the plurality of backlight sources and configured to regulate a light-emitting angle of the backlight sources of the plurality of backlight sources;
• and
• the driving assembly is configured to drive the backlight sources of the plurality of backlight sources to rotate at the preset rotation rate;
• and
• a display panel, disposed at a light-exiting side of the backlight module.
