Abstract

The invention provides a negative polymer dispersed liquid crystal film. The negative polymer dispersed liquid crystal film comprises two substrates which are opposite to each other, wherein polymer dispersed liquid crystals are arranged between the two substrates; an alignment film which is used for vertically aligning liquid crystal molecules is arranged on one side of each of the two substrates, which is adjacent to the polymer dispersed liquid crystals; the polymer dispersed liquid crystals comprise positive liquid crystals and a polymer base body; at least two electrodes are arranged on each substrate; and a horizontal electric field which is parallel to the substrates is formed between the two substrates by at least two electrodes. The negative polymer dispersed liquid crystal film is prepared by using the positive liquid crystals, the production cost of the negative polymer dispersed liquid crystal film is reduced, and preparation process is simplified.

Description

technical field [0001] The invention relates to the field of liquid crystal materials, in particular to a trans polymer dispersed liquid crystal film, a liquid crystal panel and a liquid crystal display. Background technique [0002] PDLC (Polymer Dispersed Liquid Crystal, polymer dispersed liquid crystal) is to mix LC (liquid crystal, liquid crystal) with the polymer matrix, and undergo polymerization reaction under certain conditions to form micron-sized liquid crystal droplets uniformly dispersed in the polymer matrix Among them, the dielectric anisotropy of liquid crystal molecules is used to obtain materials with electro-optic response characteristics, which mainly work between the scattering state and the transparent state and have a certain gray scale. PDLC film is a kind of film material with excellent comprehensive performance. By controlling its scattering state and transmission state, the transmittance of incident light can be controlled. [0003] Since the perf...
