Transform Any Space Instantly: Citystar PDLC Smart Glass — The Future of Privacy, Light, and Projection in One Glass Panel

Imagine walking into a conference room. The glass wall between you and the lobby is crystal clear — you can see colleagues walking by, natural daylight floods in, and the space feels open, airy, and connected. With one press of a button, the same panel turns into a frosted, opaque surface in less than a second. No curtains. No blinds. No awkward installation. Just pure, instant transformation.

That is the power of Switchable Smart Glass with PDLC (Polymer Dispersed Liquid Crystal) film — and it is changing the way architects, designers, developers, and business owners think about interior partitions, facades, and display surfaces.

What Is PDLC Smart Glass?

Switchable Smart Glass is a laminated glass product that sandwiches a layer of PDLC film between two pieces of glass of equal thickness, bonded together with EVA interlayer. When electricity flows through the film, the liquid crystal molecules align uniformly, allowing light to pass straight through — the glass becomes transparent. When the power is cut, the molecules scatter randomly, diffusing light and turning the glass into a frosted, opaque white surface.

This is not a coating. It is not a film you stick on later. It is glass and smart curtain integrated into one single piece of technology — a complete architectural glazing solution that combines transparency, privacy, and display capability in a single panel.

Three Transmittance Options to Match Every Project Need

We understand that no two projects are the same. That is why Filmbase offers three standard transmittance grades — 85%, 88%, and 91% — so you can choose the exact balance between clarity and privacy that your space demands.

• 85% Transmittance (085 Series): Ideal for interior partitions where you want maximum light transmission while still achieving full privacy when switched off. The on-state haze is just 6%, meaning the glass looks nearly as clear as ordinary float glass.

• 88% Transmittance (087 Series): Our most popular all-around grade, with on-state haze of only 4% — virtually invisible to the naked eye. Perfect for office meeting rooms, hotel bathrooms, and retail storefronts.

• 91% Transmittance (091 Series): The premium choice for facade applications and high-end commercial spaces where maximum optical clarity is essential. On-state haze is as low as 3%, delivering a crystal-clear view that rivals standard architectural glass.

All three grades achieve 94% haze in the off-state, ensuring complete visual privacy when you need it most. And yes — colorful options are available, so your smart glass can match your brand identity, interior design palette, or architectural vision.

More Than Privacy — It Is Also a Projection Screen

Here is where Filmbase Smart Glass truly stands apart from ordinary switchable glass: it supports rear projection.

When the glass is in its opaque (off) state, the surface doubles as a high-definition projection screen. Project videos, images, presentations, advertisements, or dynamic text directly onto the glass from behind — and your partition wall becomes a digital display.

Imagine the possibilities:

• Retail stores: Turn your storefront glass into a dynamic advertising screen after hours, while maintaining a clear view during business hours.

• Corporate lobbies: Project welcome messages, company videos, or brand stories onto partition walls that instantly become transparent when meetings end.

• Museums and exhibitions: Use glass partitions as interactive display surfaces that disappear when you need an unobstructed view.

• Hotels and restaurants: Project menus, ambiance videos, or event information onto glass dividers — then switch to clear for an open, welcoming atmosphere.

• Homes: Transform your bathroom or bedroom glass into a movie screen on demand.

Glass and smart curtain in one technology — plus a projection surface. That is three functions in one panel.

Built for Real-World Performance

Citystar Smart Glass is engineered to perform in demanding architectural environments. Here are the technical specifications that matter:

Optical Performance

• Operating voltage: 60V (safe, low-voltage operation)

• Power consumption: ≤5W per square meter — extremely energy efficient

• Viewing angle: ≥160 degrees — clarity from virtually any position

• UV blocking rate: ≥99% — protects interiors, furniture, and artwork from fading

• Infrared blocking rate: ≥60% — helps reduce heat gain and cooling loads

• Response time: OFF to ON in ≤30 milliseconds, ON to OFF in ≤200 milliseconds — near-instant transformation

Durability and Reliability

• Service life: up to 100,000 hours

• Switching cycles: ≥2 million on/off operations

• Operating temperature range: -30°C to 85°C — suitable for both indoor and demanding outdoor facade applications

• Maximum panel size: 1800mm × 2400mm — large-format panels for seamless wall installations

Glass ConfigurationOur standard construction uses two layers of 4mm super-clear glass laminated with EVA film on both sides of the PDLC layer. But we do not stop there. Filmbase Smart Glass is compatible with a wide range of glass types:

• Flat or curved panels

• Tempered safety glass

• Ultra-clear (low-iron) glass

• Low-E glass for energy-efficient facades

• Other glass specifications available on request

This means you can integrate smart glass into virtually any architectural project — from curved feature walls to energy-efficient curtain walls to tempered safety glass installations in public buildings.

Where Citystar Smart Glass Works Best

Citystar Switchable Smart Glass is designed for spaces that demand flexibility — spaces where the line between "open" and "private" needs to shift throughout the day.

Office SpacesConference rooms that need to be transparent for collaboration but private for sensitive discussions. Executive offices that feel spacious during the day but secure after hours. Reception areas that project professionalism while maintaining visual connection.

HospitalityHotel bathrooms where guests can enjoy an open, airy feel — then switch to complete privacy with a single touch. Restaurant private dining rooms that transform from open seating to intimate enclosures. Spa and wellness areas that blend natural light with seclusion.

Retail and CommercialStorefronts that display products by day and become advertising screens by night. Fitting rooms that offer instant privacy. Showrooms that adapt between open exhibition and private consultation spaces.

ResidentialBathroom windows that eliminate the need for curtains. Bedroom partitions that let in light while maintaining privacy. Home offices that separate work from living space without sacrificing natural light.

HealthcareHospital patient rooms that balance privacy with medical staff visibility. Clinic consultation areas that can be instantly shielded. Operating room partitions that meet hygiene and safety standards.

Public and Institutional BuildingsMuseums, libraries, government buildings, and educational facilities — anywhere that requires flexible space division, daylight optimization, and the ability to display information dynamically.
