  • Patent number: 12253767
    Abstract: Provided are a method for manufacturing a PDLC membrane electrode, a negative pressure platform, and a PDLC membrane. The method for manufacturing a PDLC membrane electrode includes the following steps: placing a PDLC membrane on a negative pressure platform with a side to be processed facing upwards, and making a liquid crystal activation area of the side to be processed of the PDLC membrane coincide with a transparent area of the negative pressure platform, and other area coincides with a main body area of the negative pressure platform; activating a liquid crystal layer of the PDLC membrane; cutting and tearing off, according to a half-cut area, a PET layer and an electric conduction layer located on the liquid crystal layer, and sweeping or tearing off the activated liquid crystal layer together to expose the electric conduction layer below the liquid crystal layer to form a corresponding electrode.

  • Patent number: 8390766
    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.

  • Publication number: 20080317977
    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.
