Abstract

The embodiment of the invention provides a light source assembly, a backlight module and a display device, relates to the technical field of display, and aims to realize the purposes that total emission can be avoided when light emitted from a light emitting diode enter to a quantum dot adhesive layer from the pipe wall of a quantum pipe and the light extraction efficiency can be improved. The light source assembly comprises the light emitting diode and the quantum tube, wherein the quantum tube is arranged on a light emission side of the light emitting diode, and comprises the pipe wall of the quantum pipe and the quantum dot adhesive layer which is arranged in an inner chamber defined by the pipe wall of the quantum pipe; the pipe wall of the quantum pipe comprises a first quantum pipe wall on the light entering side of the quantum pipe; in the width direction of the first quantum pipe wall, the middle area of the first quantum pipe wall is thicker than areas, on two sides of the middle area, of the first quantum pipe wall. The light source assembly provided by the invention is applied to the field of liquid crystal display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light source assembly, a backlight module and a display device. Background technique [0002] An existing liquid crystal display device includes a liquid crystal screen and a backlight module for providing backlight for the liquid crystal screen. The backlight module includes an optical film and a light source assembly. In order to meet the high color gamut requirements of liquid crystal display devices, such as figure 1 As shown, in the prior art, it is proposed to adopt a combination of light emitting diode 11 (Light Emitting Diode, LED) and quantum tube 12, wherein a quantum dot glue layer 121 is arranged in the quantum tube wall 120 of the quantum tube 12 to emit light. The diode 11 can emit monochromatic light, and the monochromatic light emitted by the light-emitting diode 11 can excite the quantum dots in the quantum dot glue layer 121 to realize the output of white li...
