LCG® Smart Glass Technology

Some call it smart glass. We call it LCG®.

LCG® (Light Control Glass) with Polymer Dispersed Liquid Crystal (PDLC) or Suspended Particle Device (SPD) technology by Gauzy creates dynamic, light-controlled spaces by applying technology to new and existing glass. PDLC Smart Glass can change glass from opaque to clear giving you privacy and temperature control with the click of a switch. SPD smart glass blocks 99% of light, allowing windows to dim and tint without blocking views, making it the optimal shading choice for exterior windows across industries.

LCG® Smart Glass is available with two distinct technologies: PDLC or SPD

Gauzy is the only LCG® smart glass technology company in the world that develops, manufactures, and markets both PDLC and SPD films for lamination or aftermarket installation by industry professionals.

Gauzy PDLC Smart Glass

Benefits of LCG® Smart Glass with PDLC technology:

  • on, off, or anywhere in between in milliseconds
  • privacy or an open atmosphere instantly
  • rear projection screen or whiteboard use when opaque
  • temperature control through exterior windows with Solar Control LCG® films
  • allow light to flow between spaces for greater wellbeing and energy optimization
  • easily connected to Lutron or other automation and lighting control systems

Gauzy SPD Smart Glass

Benefits of LCG® Smart Glass with SPD technology:

  • dim or tint glass to the perfect shading level
  • switches in milliseconds unlike electrochromic glass
  • blocks glare without blocking views for greater connection to surroundings
  • easily connected to Lutron or other automation and lighting control systems
  • available in architectural widths and custom shapes and sizes
  • shading directly in architectural or automotive glazing

Gauzy works exclusively with OEM’s, Tier 1 suppliers, and brands to supply the automotive industry with LCG® smart glass technologies. To learn more visit our automotive page.

LCG® Smart Glass Composition

Gauzy’s LCG® technology consists of specially developed SPD emulsions or PDLC formulations that are coated between two sheets of PET-ITO, and then UV cured, creating a single film. These films are laminated into, or installed onto, glass by Gauzy’s extensive network of trained and certified professionals worldwide.

LCG® Smart Glass Film Types

Gauzy manufactures two different kinds of films: one for lamination and one for retrofitting onto existing glass. PDLC technology is available as as a laminated smart glass or adhesive smart film. SPD technology is available as laminated smart glass.

How LCG® Smart Glass Works

Example of PDLC film in its "On" state
When off, particles are scattered creating opacity for privacy, shading, solar control, or projection.

PDLC and SPD smart glass technology is an active glass technology that switches states with electricity. The unique particles or molecules inside our films scatter or align as films are turned on and off, allowing light to pass through for opacity or transparency, and the switchable control of various forms of light (visible, IR, UV).
