Title:
OPTICAL DIFFUSION FILM PREPARATION METHOD AND BACKLIGHT MODULE
Document Type and Number:
WIPO Patent Application WO/2020/164254
Kind Code:
A1
Abstract:
Provided are an optical diffusion film preparation method and a backlight module, comprising: removing impurities from cellulose crystallite to obtain a first solid compound, adding the first solid compound into a surfactant solution, and vigorously stirring to form a dispersion liquid A; dissolving a dye in distilled water to form a solution B, mixing the solution B with the dispersion liquid A, performing a centrifugal treatment to form a second solid compound, dispersing the second solid compound into a polymer precursor solution, stirring and ultrasonically dispersing to form a cellulose nanocrystalline dispersion liquid; and finally curing to form the optical diffusion film.
