What is Switchable PDLC Glass? A Comprehensive Guide

Switchable PDLC glass is an innovative glass technology that allows you to control the level of transparency. PDLC stands for Polymer Dispersed Liquid Crystal, which are films of liquid crystal droplets dispersed in a polymer that can be switched from transparent to opaque when a voltage is applied. This enables you to change the glass from clear to translucent or frosted at the flip of a switch.

Switchable PDLC Glass also call Smart Privacy Glass, electric privacy glass for window, electronic privacy glass, Functional Glass, Privacy glass, privacy glass for partition, glass for window and door, Smart glass electric switchable glass for Door, Smart Glass Office partitions, Switchable Electrochromic Glass.

How Does Switchable PDLC Glass Work?

The core of PDLC glass is a layer of liquid crystal film sealed between two sheets of glass or plastic. When no power is supplied, the liquid crystals scatter light in random directions, causing the glass to appear frosted or cloudy. But when voltage is applied, the liquid crystals align in a uniform direction, allowing most light to pass directly through so the glass becomes transparent.   

The amount of transparency is determined by the strength of the voltage applied. Low voltage results in minimal light transmission for maximum privacy, while higher voltage produces nearly see-through clarity. This enables step-less control of transparency, from opaque to clear. When the power is cut, the glass immediately returns to its frosted state.
