Abstract
A backlight module and a display device having same are provided in the present disclosure. The backlight module includes a plurality of backplanes that are combined, where a plurality of light-emitting units are disposed. Each of the light-emitting units includes a first light-emitting unit located in the combining areas of the adjacent backplanes, and a second light-emitting unit located in the other areas of the backplanes. In at least one backplane, a first resistance between the first light-emitting unit and the corresponding power source high-potential signal input terminal is smaller than a second resistance between the second light-emitting unit and the corresponding power source high-potential signal input terminal.
