Title:
LIGHT CONVERSION FILM WITH SIMPLIFIED BARRIER FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/077717
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of light conversion films, and particularly relates to a light conversion film with a simplified barrier film and a preparation method therefor. The light conversion film comprises a barrier film and a barrier layer plated on the surface of the upper layer of the barrier film, wherein a thin film stack is attached to the surface of the lower layer of the barrier film; the barrier film comprises a barrier copolymer material, a photoluminescent material, TiO2, an antioxidant, white oil and other additives; the barrier layer comprises Al2O3 and SiOx; and the thin film stack is high- and low-refractive-index materials. The preparation method comprises the steps of: (1) the preparation of a barrier film, involving: stirring and mixing a barrier copolymer material, a photoluminescent material, TiO2, a hindered phenol antioxidant, white oil and other additives, subjecting the resulting mixture to melting, pulling, cooling, cutting-off, and tape casting and rolling, so as to obtain a barrier film; and (2) the preparation of a light conversion film, involving: plating a barrier layer onto the surface of the upper layer of the barrier film, and attaching a thin film stack to the surface of the lower layer of the barrier film, so as to obtain a light conversion film. By means of the present invention, the light conversion film is convenient to prepare, and has relatively good optical performance and barrier performance.
