PDLC Glass: The Smart Glass Technology Explained
PDLC (Polymer Dispersed Liquid Crystal) glass, also called smart
switchable glass, is an advanced glazing solution that instantly
changes from transparent to opaque with the flip of a switch. It
combines privacy, energy efficiency, and modern design in one
innovative system.
1. How PDLC Glass Works
Core Structure:
Two layers of glass (tempered or laminated)
PDLC film sandwiched between (liquid crystals + polymer)
Transparent conductive coating (ITO electrodes)
Operating Principle:
| State | Power OFF | Power ON |
| Appearance | Frosted/opaque | rystal clear |
| Light Transmission | <5% | >80% |
| Liquid Crystal Alignment | Random (scatters light) | Ordered (allows light through) |
| Transition Time | 0.1–0.5 seconds |
2. Key Features of PDLC Glass
| ✔ Instant Privacy Control | Frosted for confidential meetings → Clear for collaboration |
| No need for blinds or curtains |
| ✔ Energy Efficiency | Blocks 99% UV rays (protects interiors from sun damage) |
| Reduces glare & heat gain (cuts cooling costs) |
| ✔ Smart Integration | Controlled via: Wall switch Mobile app (Bluetooth/WiFi) Voice commands (Alexa/Google Home) Automation (scheduled or light-sensor triggered) |
| ✔ Safety & Durability | Laminated options (6+6mm with PVB interlayer) |
100,000+ switching cycles (10+ years of daily use) |
| ✔ Customization | Tinted/frosted patterns |
| Brand logos etched into glass |
Curved or oversized panels |
3. Applications of PDLC Glass
| Industry | Uses |
| Offices | Conference rooms, CEO suites |
| Healthcare | ICU windows, exam rooms |
| Hospitality | Hotel room partitions, spa doors |
| Residential | Bathroom enclosures, smart home dividers |
| Retail | Interactive display windows |
4. PDLC vs. Alternatives
| Feature | PDLC Glass | Traditional Blinds | Electrochromic Glass |
| Privacy Speed | Instant (0.5s) | Slow (manual) | Slow (minutes) |
| Energy Savings | High | None | Moderate |
| Maintenance | Zero | Dust cleaning | Minimal |
| Cost | $$$ | $ | $$$$ |
