Patent number: 8390766Abstract: 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.Type: GrantFiled: June 24, 2011Date of Patent: March 5, 2013Assignee: Chiefway Engineering Co., Ltd.Inventor: Yung-Lung Wu
