Abstract

The invention discloses a high-brightness polymer dispersed liquid crystal thin film with a fluorescent effect, and a preparation method thereof. The liquid crystal thin film sequentially comprises afluorescent substance coating, a first conductive transparent thin film layer, a liquid crystal thin layer doped with fluorescent substances and a second conductive transparent thin film layer from top to bottom; the first conductive transparent thin film layer and the second conductive transparent thin film layer are both polyethylene terephthalate conductive transparent films plated with indiumtin oxide, and the conductive surfaces of the first conductive transparent thin film and the second conductive transparent thin film are opposite. The liquid crystal thin film has the advantages of being high in brightness, rich in color and the like.

Description

technical field [0001] The invention relates to the technical field of liquid crystal application, in particular to a polymer-dispersed liquid crystal film with fluorescent effect and high brightness and a preparation method thereof. Background technique [0002] Due to its good photostability and superior photoelectric properties, fluorescence is widely used in lighting, molecular tracking, fluorescent display and other fields. Especially the development of fluorescent display has aroused people's strong interest in fluorescence. [0003] The traditional fluorescent display uses high-speed electrons to bombard the phosphor to make the phosphor emit light. It is a self-luminous display device. It has the advantages of colorful display, high brightness, wide viewing angle range, fast dynamic response, and easy integration of integrated circuits. A typical representative of a traditional fluorescent display is a CRT (Cathode Ray Tube, cathode ray tube) display, which is curren...
