Abstract: A light-regulation membrane easy for installation and maintenance is disclosed to include a PDLC film having two conducting layers prepared by high-reflection black and transparent materials made by means of depositing titanium oxide on a base layer of polyethylene terephthalate by means of spattering deposition and electrically connected to an external power source and a liquid crystal layer sandwiched between the conducting layers, a surface structure consisting of a hard coating layer and an anti-stain layer on one side of the PDLC film, and an adhesion layer formed the opposite side of PDLC film and releasably adhered to a transparent object. So, the transparency of the light-regulation membrane can be regulated from opaque to clear or reversely while the transmittance of the PDLC film being adjusted by the power, and then any light source passing through the light-regulation membrane can be controlled.

Abstract: A light-regulation membrane includes a surface structure having an anti-stain layer for surface cleanness, a hard coating layer for surface protection, and anti-reflective layer sandwiched between the anti-stain layer and the hard coating layer for reducing glare and ultra-violet; an adhesion layer for directly and repetitively adhering on transmissible plate even after peeled-off; two polymer compound layers sandwiched between the hard coating layer and the adhesion layer; and a PDLC (polymer dispersed liquid crystal) film sandwiched between the two polymer compound layers comprising two conducting layers and a liquid crystal layer sandwiched in-between the two conducting layers. The two conducting layers can be connected to an electric power source.
