Title:
OPTICAL FUNCTIONAL THIN FILM
Document Type and Number:
WIPO Patent Application WO/2023/124993
Kind Code:
A1
Abstract:
An optical functional thin film, sequentially comprising a release layer (05), a bonding layer (04), a substrate layer (01), an optical structure layer (02) and a filling layer (03). The optical structure layer (02) refracts light to increase a viewing angle. A surface of the filling layer (03) is provided with a fluctuating structure. The optical functional thin film can be used for being externally attached to the outer side of a screen of a liquid crystal display device, and is used for alleviating the defect of horizontal or vertical brightness viewing angles of existing liquid crystal display devices being narrow (small); and the fluctuation of a color cast value viewing angle curve is relatively low, such that the subjective feeling during the use of the liquid crystal display device to which the optical functional thin film is attached is better.
