Abstract

The invention provides a resin composition which is characterized by comprising the following components in percentage by weight: 60.00-95.00% of an organic resin, 0.01-5.00% of an initiator, 0.10-10.00% of hydrophobic fumed silica and 1.00-30.00% of obstruction particles which are uniformly dispersed in the organic resin. A light conversion element based on the resin composition is good in stability and long in service life, and the problems that a conventional quantum dot material is poor in stability and short in service life in the use process are effectively solved.

Description

technical field [0001] The invention relates to the technical field of encapsulation of quantum dot materials, in particular to a resin composition, a light conversion element and a light source assembly. Background technique [0002] Quantum dots are inorganic semiconductor luminescent nanocrystals with a three-dimensional size in the range of 1-20nm. Because their size is smaller than or close to the exciton Bohr radius, quantum dots have a wide range of excitation wavelengths, controllable particle size, narrow half-width, Stokes shift and other advantages. Compared with the white light emitted by the traditional backlight, the quantum dot-based backlight can get more pure red and green light, so the display is brighter, and it can increase the color gamut of the liquid crystal display from 70% NTSC to 110% NTSC, so Quantum dots are widely used in the field of display. [0003] The existing quantum dot backlight display technology can be mainly divided into On-edge stru...
