Abstract

The invention discloses a light source assembly, which comprises a substrate (241), dot light sources (242), at least two brackets (243) and a quantum tube (244), wherein the dot light sources (242) are arranged on the substrate (241) at intervals; the brackets (243) are fixedly arranged on the substrate (241) and are arranged near the dot light source (242); the quantum tube (244) is fixedly arranged in the brackets (243). The invention also discloses a backlight module and a liquid crystal display device with the light source assembly. The light source assembly has the advantages that when the quantum tube is fixedly arranged near the dot power source by the brackets, as the brackets are made of a buffer material, the quantum tube can be buffered to certain content by the brackets under the condition of outside shock or vibration, the crushing and damage of the quantum tube are avoided, and the reliability of a product is improved; the brightness of light rays entering a light guide plate is improved by a prism structure and an attached prism membrane sheet at the side surface, backward to the dot light source, of the quantum tube.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a light source assembly with high color gamut, a backlight module and a liquid crystal display. Background technique [0002] Currently, liquid crystal displays, as display screens of electronic devices, have been widely used in various electronic products. The market has higher and higher requirements for the vividness of colors displayed by electronic devices, which requires a higher and higher color gamut of liquid crystal displays as display screens of electronic devices. [0003] Generally speaking, an existing liquid crystal display includes a liquid crystal panel disposed opposite to each other and a backlight module for providing display backlight to the liquid crystal panel. As one of the most important components of a liquid crystal display, the backlight module provides the color gamut of the display backlight to the liquid crystal panel dir...
