1. A backlight module, applied to a display device comprising a display panel, wherein the display panel comprises a plurality of sub-pixels and M data lines; each of the M data lines is connected to at least two of the plurality of sub-pixels; M is an integer greater than 3;
the backlight module comprises a plurality of light-emitting elements and a controller; the plurality of light-emitting elements are in a one-to-one correspondence with the plurality of sub-pixels, such that the plurality of light-emitting elements serve as light sources for the plurality of sub-pixels respectively; the controller is configured to control a brightness of each of the plurality of light-emitting elements; and
the controller is configured to control a first brightness to be greater than a second brightness when a target gray scale of a (j+1)-th sub-pixel connected to an i-th data line of the M data lines is constant, wherein the first brightness is the brightness of the light-emitting element corresponding to the (j+1)-th sub-pixel connected to the i-th data line when a j-th sub-pixel connected to the i-th data line does not emit light the second brightness is the brightness of the light-emitting element corresponding to the (j+1)-th sub-pixel connected to the i-th data line when the j-th sub-pixel connected to the i-th data line emits light, i is an integer greater than 1 and less than M, and j is a positive integer.
