Abstract

The invention provides a direct type backlight module and a display device, and belongs to the technical field of display. The direct type backlight module comprises a back plate, a light source assembly and a quantum dot assembly, wherein the light source assembly is arranged on one side of the back plate; the light source assembly comprises a light source driving circuit and a plurality of lightemitting devices connected to the light source driving circuit; the quantum dot assembly comprises quantum dot layers arranged on the sides, away from the back plate, of the light-emitting devices and a retaining wall surrounding all the light-emitting devices; quantum dots are contained in the quantum dot layers; and the end, far away from the back plate, of the retaining wall is connected withthe quantum dot layers. According to the direct type backlight module, a narrow frame can be achieved.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a direct-lit backlight module and a display device. Background technique [0002] Quantum dots are quasi-nanometer grains composed of hundreds or thousands of atoms, with a size ranging from 1 to 10 nm. They have good dispersion, relatively pure excitation spectrum and high quantum efficiency. Based on the photoluminescent properties of quantum dots, quantum dots can be used as excellent fluorescent materials in the backlight module of liquid crystal displays to improve the color purity and color saturation of the display. [0003] In the quantum dot backlight module, there will be blue light leakage around the backlight, which reduces the display effect. In order to block the leaked blue light, it is necessary to add light-shielding tape around the backlight module or print light-absorbing materials around the light guide plate, which is not conducive to the narrow fr...
