Zusammenfassung:The disclosure discloses a light source unit, a backlight module and a display device, wherein the light source unit comprises a printed circuit board and a plurality of light source groups, the plurality of light source groups are arranged on the printed circuit board, and each light source group at least comprises a red light source, a green light source and a blue light source; the plurality of light source groups are divided into a plurality of regions, and each region is independently controlled. According to the disclosure, the light source groups are divided into regions, and the display signals of the light source groups in each region are controlled through independent control switches, so that the backlight LED light source can be lighted regionally in high brightness and high color gamut region, and the energy consumption is reduced.
