Abstract
A quantum dot film, a method of preparing the same, and a display device are disclosed. The quantum dot film includes a quantum dot layer and a plurality of protection layers. The quantum dot layer includes a plurality of red quantum dots, green quantum dots and scattering particles, which are uniformly dispersed in a high molecular polymer substrate. Material of the plurality of scattering particles is high refractive index material with a particle size ranging from 200 nm to 1 μm. By the plurality of scattering particles with a high refractive index disposed in the quantum dot layer, the self-absorption phenomenon between a plurality of quantum dots is reduced, and a light extraction rate is improved.
