Abstract
The present disclosure relates to a backlight module, a method for designing the same, and a display device. The backlight module includes: a first substrate; a plurality of LED chips on the first substrate; and a light control structure on the first substrate. The backlight module includes a plurality of light control region groups in one-to-one correspondence with the plurality of light-emitting diode chips, each light control region group includes at least a first light control region and a second light control region. The light control structure includes a plurality of light control substructure groups respectively located in the plurality of light control region groups. Each light control substructure group includes at least a first light control substructure in the first light control region and a second light control substructure in the second light control region.
