The quantum dot LED backlight light source structure comprises a reflection cup shell, a blue light chip structure and a red light chip, wherein the reflection cup shell is used for mounting a quantum dot LED; the blue light chip structure and the red light chip are arranged at the bottom in the reflection cup shell; at least one blue light chip structure is arranged; at least one red light chip is arranged; the blue light chip structure comprises a blue light chip and a green light quantum dot fluorescent powder layer arranged on the blue light chip; and the blue light chip structure and the red light chip are formed into the quantum dot LED. The quantum dot LED backlight light source structure can effectively reduce the Cd content of quantum dot package LED backlight and can achieve the aim of quantum dot packaging structure meeting RoHS and high color gamut coverage.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of flat panel display technology, in particular to a quantum dot LED backlight light source structure and a display device. [0003] 【Background technique】 [0004] Quantum Dots are extremely small semiconductor nanocrystals that cannot be seen by the naked eye, and are particles with a particle size of less than 10 nanometers. Generally speaking, quantum dots are composed of zinc, cadmium, selenium and sulfur atoms. Quantum dots have a unique characteristic, that is, whenever stimulated by light or electricity, quantum dots will emit colored light, and the color of light is determined by the composition material and size and shape of quantum dots. This characteristic enables quantum dots to change The color of the light emitted by the light source. As a new type of luminescent material, quantum dots have the advantages of high light color purity, high luminous quantum efficiency, adjustable luminous color, ...
