How Is Privacy Glass Powered?

‍Ever wondered how privacy glass can switch from frosted to clear in an instant?
‍
This cutting-edge technology, often called Smart Glass, Smart Film, Switchable Glass, or Electric Privacy Glass, is powered by a safe and efficient low-voltage electrical system.
In this post, we’ll break down exactly how it works — and what powers the transformation.

What Is Privacy Glass?
‍

Privacy glass is a type of glass that changes transparency with the application of electricity.
When powered, it becomes clear; when the power is off, it turns opaque or frosted.
This makes it ideal for offices, homes, medical facilities, hotels, and storefronts that need privacy on demand — without curtains, blinds, or partitions.

At Smart Glass Country, our privacy glass solutions include both Smart Glass and Smart Film — two technologies that deliver the same result but in different formats.

The Power Behind Smart Glass and Smart Film
‍

So, how is Smart Glass powered?

Both Smart Glass and Smart Film use PDLC technology (Polymer-Dispersed Liquid Crystal) — an advanced material science innovation that reacts to electricity.

Here’s how it works:

• OFF (Opaque State):
  When no electrical current is applied, the liquid crystals inside the glass are randomly arranged. This scatters light and makes the glass appear frosted or opaque.
  
  
• ON (Clear State):
  When a low-voltage electrical current passes through the glass, the liquid crystals align in a uniform direction, allowing light to pass through. The glass instantly becomes clear.
  
  

This process happens in milliseconds, using minimal power and no moving parts — just pure electrical science in action.

The Electrical System: Safe, Simple, and Efficient
‍

Privacy Glass and Smart Film are powered by a low-voltage transformer that converts standard building electricity (110V or 220V) into a safe low-voltage current.

That current energizes the PDLC layer inside the glass or film, making the crystals align and switch transparency.

The system includes:

• Low-voltage transformer – safely converts power
  
  
• Controller – manages the current flow
  
  
• Switch or control module – lets you turn the glass ON or OFF
  
  

The wiring is typically concealed within window frames, walls, or door structures for a clean, professional finish.

Control Options for Privacy Glass
‍

Once installed, you can control your Smart Glass or Smart Film in several ways:

• Smart Home Automation – Connect with Alexa, Google Home, or Lutron systems
  
  
• Wall Switch or Remote – Simple, manual control
  
  
• Smartphone App – Change privacy settings from anywhere
  
  
• Timed or Sensor-Based Automation – Automate based on time of day or motion
  
  

These options make electric privacy glass and electric window tint some of the most flexible privacy solutions available.

Safety Considerations
‍

All of Smart Glass Country’s products are designed with electrical safety in mind.
The power supply operates at low voltage, and all connections are clearly marked for quick, reliable installation.

⚠️ Important: Wiring should always be performed by a certified electrician to ensure compliance with local electrical codes and maintain warranty coverage.
‍

Energy Efficiency and Power Consumption
‍

Privacy Glass and Smart Film are designed to be energy efficient.
They consume only a few watts per square meter — significantly less than a standard light bulb.

This makes them ideal for sustainable building design and LEED-certified projects, helping control light, glare, and heat gain while maintaining a modern aesthetic.
