Abstract: 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.

Abstract: A backlight module comprising a lamp strip (10), a light guide plate (20), a quantum dot glass tube (30) and a fixing part (40). The fixing part (40) is a hollow structure. The quantum dot glass tube (30) being provided in the cavity of the fixing part (40) which is positioned between the lame strip (10) and the light guide plate (20). One side wall of the fixing part (40) is abutting on the frame of the lamp strip (10), and the other side wall of the fixing part (40) is engaging with the light guide plate (20). The fixing part (40) is utilized to place the quantum dot glass tube (30), so as to maintain proper distance among the lamp strip (10), the light guide plate (20) and the quantum dot glass tube (30), and fix the lamp strip (10) and the light guide plate (20).
