The invention discloses a kind of quanta point material and preparation method, quantum dot film, backlight module, display equipment, belong to technical field of liquid crystal display.Wherein the preparation method of quanta point material includes: step a, and preparation is dispersed with the wet gel of quantum dot；The wet gel is transparent organic polymer gel or transparent inorganic matter gel；The wet gel is transformed into aeroge using supercritical drying or freeze-drying, obtains the quanta point material by step b.Quantum dot is loaded using the three-dimensional net structure of aeroge, make quantum dot orderly and is controllably dispersed in the skeleton structure of aeroge, prevent quantum dot from reuniting, reduce quantum dot Duplication, to improve the luminous efficiency of the quantum dot film based on the quanta point material, and then the brightness of backlight module is promoted, be conducive to the development of high colour gamut liquid crystal display. |
