Abstract

The invention provides an electronic louver film based on PDLC liquid crystal light adjusting film. The electronic louver film comprises PET1 and PET2, a PDLC layer is arranged between PET1 and PET2,ITO layers are arranged between the PDLC layer and PET1 and between the PDLC layer and PET2 respectively and are provided with etching lines, and electrodes are arranged on the ITO layers at the etching line sides. The invention provides the electronic louver film based on the PDLC liquid crystal light adjusting film and a control system of the PDLC liquid crystal light adjusting film. The louverfilm achieves transparency at any range and the functions of adjusting the dull-polish area and displaying a pattern, so that the applicability of the louver film is wider, and the safety performanceis higher.

Description

technical field [0001] The invention belongs to the technical field of PDLC liquid crystal dimming film, in particular to an electronic louver film, glass and control system based on PDLC liquid crystal dimming film. Background technique [0002] Electronically controlled liquid crystal dimming film refers to an optical film made by the liquid crystal polymer technology (PDLC) invented in the United States. This technology mainly applies the mixing of nematic liquid crystal and molecular polymer, and by controlling the alignment state of the liquid crystal, the internal refractive index is different, and the macroscopic state of light transmission and astigmatism is switched. [0003] A Chinese patent with the publication number CN101059607A discloses an electronically controlled liquid crystal dimming glass and film. This invention uses smectic liquid crystal as the main material, which is coated between two layers of media through a special processing technology, such as t...
