High Privacy PDLC Switchable Smart Glass Pane

PDLC Smart Glass

PDLC  Smart Glass is a type of laminated glass via wiring PDLC film. When electricity is applied to the film, the liquid crystals align and the glass becomes clear; when the power is turned off, the liquid crystals return to their normal scattered positions rendering the glass an opaque translucent. It switches your glass from clear to frost with smart glass technology so it is named switchable glass, smart glass panel, laminated smart PDLC glass.

PDLC Switchable Smart Glass have been widely used in homes, conference rooms, office partition, hospitals, schools, military, hotels and so on.

PDLC (Polymer Dispersed Liquid Crystal) smart glass, also known as switchable glass or privacy glass, is a versatile glazing technology that offers a range of features and benefits. 

Key features of PDLC smart glass

Privacy Control: PDLC smart glass can switch between opaque and transparent states with the flick of a switch or a remote control. This feature provides instant privacy for spaces like bathrooms, meeting rooms, or bedrooms when needed, and transparency when desired.

Light Control: It allows you to control the amount of natural light entering a space. When the glass is in the opaque state, it can block a significant amount of light, providing shading and reducing glare.

Energy Efficiency: PDLC smart glass can enhance energy efficiency by reducing the need for curtains or blinds to control light and privacy. This can help reduce heating and cooling costs in buildings.

UV Protection: When in the transparent state, PDLC smart glass can block a portion of harmful UV rays, protecting interior furnishings, artwork, and occupants from UV-related damage and health risks.

Sound Insulation: It offers some level of sound insulation, which can help create quieter and more comfortable indoor environments by reducing external noise.

Aesthetic Versatility: PDLC smart glass can be customized with various tints, colors, and patterns to match the design aesthetics of a space. This makes it suitable for both residential and commercial applications.

Security: In the opaque state, PDLC smart glass acts as a security feature by preventing visual access into a space, enhancing the security and privacy of the area.

Ease of Installation: PDLC smart glass can be retrofit into existing window openings or incorporated into new construction projects, making it a versatile choice for both renovations and new builds.

Remote Control and Automation: The glass can be controlled remotely using a switch, remote control, smartphone app, or integrated into building automation systems for convenient and automated operation.

Low Maintenance: PDLC smart glass is relatively low-maintenance. Cleaning it with standard glass-cleaning products is usually sufficient to maintain its appearance and functionality.

Durable: It is designed to be durable and long-lasting, with the ability to switch between states thousands of times without significant degradation.

Privacy Partitions: PDLC smart glass is often used to create movable privacy partitions in offices, allowing for flexible use of space while maintaining privacy when needed.

SMART Thin Film Technology

Polymer Dispersed Liquid Crystals (PDLC)
1. Without power, the liquid crystal molecules (microdroplets) are disordered. This prevents light from penetrating the film and making it opaque.
2. when smart films are energized, the liquid crystal molecules are forced to align, making them transparent.

Smart film, also known as dimmable film, is a product capable of adjusting light transmission between transparent and opaque using an AC power source. Due to their sensitivity to humidity, early versions of the film were only used to create smart glass by laminating it to glass. As moisture resistance continues to improve, a new generation (third generation) of film can be installed directly onto existing windows using special glues or self-adhesives. It combines a variety of functions such as dimming, UV and IR blocking, advertising and security.
Most film applications are made through glass, acrylic or polycarbonate laminates and are primarily related to the voltage (110VAC) required to operate the film. The company continues to experiment with various installation methods in order to utilize the film directly without the added cost of lamination.
One of the advantages of Smart Film is that it eliminates the need for blinds, shades or curtains.

How Smart Glass Works

A simple on/off mode switches Smart Switchable film from clear to translucent. In clear mode, smart switchable glass looks like any other traditional glass panel, providing unobstructed views and daylight penetration.
In translucent mode, Smart Switchable film acts as an electronic blind, providing privacy and security while still allowing daylight to pass through. In "on" or "clear" mode, an electric current is passed through a PDLC (Polymer Dispersed Liquid Crystal) sandwich that aligns microscopic crystals along parallel axes, allowing a view through the glass.
In "off" or "semi-transparent" mode, no current is applied, so the PDLCs are randomly arranged in the droplets, scattering light as it passes through the film. This results in a fuzzy milky color that obstructs the view through the glass.

Application

​In the office
Applied to the glass enclosure of a conference room. When the glass is transparent, one can see into or out of the room, and when it is non-transparent it can be used as a projection screen.
Energy-saving function of glass curtain wall
Indoor decoration of up-scale residence
Lighting cover glass curtain, sunshine house, living room and bathroom compartment. The glass is in a cloudy state when out of use, which protects privacy, and when it turns to transparent, one may fully bathed in sunshine.
Product display and commercial advertisement
Glass display window, protect the products when it is non-transparent, and may used for projection to introduce products; when it is transparent, it may be used for store advertising.
Use for special occasions
The glass door of a rest room is transparent when not in use, and immediately turns to a cloudy state when the door is closed.
Glass floor and stairs on the second floor appear cloudy when walked upon, otherwise they are transparent.
Privacy uses in hospitals, e.g., windows of infants' room and intensive care units, replacing curtains, to reduce dust and noise.
Applied to dust-free rooms and cleaning rooms, smart films may be used to switch between transparent and non-transparent, and can reduce inconvenience for customers having to wear dust-free clothes passing in and out of the room.
