PDLC Switchable Privacy Glass
PDLC (polymer dispersed liquid crystal) switchable glass contains a liquid crystal film laminated between glass lites that turns from opaque (frosted) to clear when an electrical current is applied, providing instant, on-demand privacy without blinds or curtains.
Product Overview
PDLC (polymer dispersed liquid crystal) switchable glass contains a liquid crystal film laminated between glass lites that turns from opaque (frosted) to clear when an electrical current is applied, providing instant, on-demand privacy without blinds or curtains.
Key Features
Switches between opaque and clear states electronically, requires no mechanical blinds or curtains, can be integrated with sensors, timers, or building automation systems, and retains standard laminated glass safety properties.
Where This Glass Is Used
Conference rooms, healthcare partitions, hospitality privacy screens, and any application requiring switchable privacy.
Manufacturing Process
- PDLC film lamination — A polymer dispersed liquid crystal film is laminated between two glass lites using a standard lamination process, similar to laminated safety glass.
- Electrical connection — Conductive coatings on the film are wired to a low-voltage power supply and control switch, timer, or building automation interface.
- State switching — Applying voltage aligns the liquid crystals for a clear state; removing voltage returns the film to its default opaque/frosted state.
- Safety base glass — The base glass lites can be tempered or laminated to meet safety glazing requirements independent of the PDLC function.
Applications & Use Cases
- Conference Room Partitions — Instant privacy for meetings without blinds, maintaining a clean architectural aesthetic.
- Healthcare Privacy Screens — Switchable privacy for patient consultation rooms and treatment areas.
- Hospitality Bathroom Partitions — Switchable glass between bedroom and bathroom spaces in hotel suites.
- Retail & Display Windows — Switches between showcase and private-storage modes for retail display applications.
