Abstract

The invention discloses a quantum dot luminous device and a backlight module. The backlight module comprises a back plate and a diffusion plate overlapped in sequence, wherein multiple quantum dot luminous devices are arranged on the surface of the back plate facing the diffusion plate. The quantum dot luminous device comprises an LED luminous chip, a bracket structure and a lens integrated structure, wherein the lens integrated structure comprises a lens body, a quantum dot layer and a first water-oxygen spacing layer; the lens body is provided with a concave part; the concave part is provided with the quantum dot layer and the first water-oxygen spacing layer sequentially from the bottom end to an opening; the first water-oxygen spacing layer covers the opening of the concave part of the lens body; and the lens integrated structure is fixedly glued with the bracket. In the invention, the failure rate of quantum dot excitation and the manufacturing cost are reduced to a great degree.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a quantum dot light-emitting device and a backlight module. Background technique [0002] A liquid crystal display device includes an LCD liquid crystal panel for displaying image content and a backlight module for providing a white light source to the LCD liquid crystal panel. The color gamut range of the white light source of the backlight module determines the color gamut range in which the liquid crystal display presents image content. In order to improve the color gamut range of the white light source, a blue LED chip is used to excite the quantum dots to emit green light and red light, and the green light, red light and unexcited blue light are mixed to form a white light source. [0003] Quantum Dot (Quantum Dot) is a quasi-zero-dimensional nanocrystal, composed of a small number of atoms, generally spherical or spherical in shape, and made of s...
