Abstract
(EN)
Disclosed are a quantum dot composite film preparation method and a backlight module. The quantum dot composite film preparation method comprises the following steps: preparing a metal nanoparticle dispersion liquid; preparing a metal plasma structure thin film; and preparing a quantum dot composite film: coating the metal plasma structure thin film with a polymer colloid on which quantum dots are dispersed, said polymer colloid forming a quantum dot structure layer, and performing drying and curing, so as to obtain a quantum dot composite film.
