Conventional privacy solutions trade one problem for another. Blinds and curtains collect dust, block daylight entirely, and wear out through mechanical cycling. Frosted glass is irreversible — the space permanently loses its view and natural light. Decorative window film is static with no switching capability.
The underlying mechanism is always mechanical: every moving privacy surface introduces friction, dust accumulation, and a fixed trade-off between daylight and privacy. Smart film resolves this at the material level through liquid crystal molecular orientation control — no moving parts, no dust path, no mechanical wear. Daylight is preserved in the transparent state; privacy arrives in the opaque state; the transition completes in ≤ 60 milliseconds for PDLC and continuously for SPD.
Two switchable film technologies — PDLC and SPD — plus the power supplies, controllers, and installation accessories needed for project-ready deployment.
PDLC (Polymer Dispersed Liquid Crystal) film sandwiches microscopic liquid crystal droplets in a polymer matrix between two PET/ITO conductive layers. In the OFF state, LC droplets orient randomly, scattering light to produce the frosted privacy appearance. When 48/65V AC is applied, the LC molecules align along the electric field, matching the polymer refractive index — light passes through and the film turns transparent. The transition completes in ≤ 60 ms (≤ 20 ms for PRO models). AC voltage is essential to prevent polarization that would degrade the LC over time.
SPD (Suspended Particle Device) film uses a different mechanism: microscopic particles suspended in a fluid layer between conductive substrates. OFF: particles scatter randomly (deep blue, ≤ 2% VLT). ON: 90V AC aligns particles into columns (≥ 60% VLT). SPD transitions are slower (≤ 9 s) but offer continuous 30:1 dimming rather than binary switching. Both technologies use AC to prevent polarization damage to the active layer.

Each scenario lists the parameters that drive model selection and installation planning.
Conference rooms need privacy on demand without blocking daylight or the open-plan feel. PDLC partitions switch opaque in ≤ 60 ms for confidential discussions and clear again instantly. Scheduled Wi-Fi automates the daily open/closed cycle for partitions and storefronts.
Treatment rooms and consultation areas need instant privacy that complies with hygiene standards. Self-adhesive film applies to existing glass partitions with no demolition. Neutral-cure silicone edge seal protects against humidity and cleaning agents. Switching 20–50 times daily is routine.
Hotel suites and front-of-house partitions need premium instant privacy. PDLC film integrates with smart-home bridges for guest-controlled ambiance. UV rejection 93.8–96% protects interior finishes and artwork. PRO models deliver 165° viewing angle for lobby glazing.
After-hours privacy and projection-ready display surface in one product. Switching to opaque blocks visibility while allowing projected campaigns onto the glass. Wi-Fi scheduling automates the daily open/closed cycle. EL-X2-PRO delivers 97% total VLT for maximum daytime transparency.
Bathrooms, bedroom partitions, and home offices need humidity-tolerant privacy that still admits daylight. Self-adhesive film applies directly to existing glass, sized 2–3 mm shorter than the visible pane. HomeKit, Google Home, and Alexa integration for hands-free control.

PDLC (Polymer Dispersed Liquid Crystal) switches between clear and frosted in ≤ 60 ms (≤ 20 ms for PRO models) — a binary opaque/transparent transition at 3.7 W/m². SPD (Suspended Particle Device) offers continuous dimming from ≥ 60% VLT to ≤ 2% VLT over ≤ 9 seconds, operating at 90V AC and drawing 3 W/m² when transparent, 0 W when opaque. PDLC is self-adhesive and retrofit-friendly; SPD is typically laminated. Choose PDLC for instant binary privacy; choose SPD for gradual tint control on facades or skylights.
Yes. ElevatoX self-adhesive PDLC film uses a dry-install adhesive backing applied directly to existing glass — no demolition, no water during installation. SPD film is typically laminated and requires autoclave processing. For detailed installation steps and edge-sealing rules, see the PDLC film product page.
PDLC film operates on 48/65V AC at 3.7 W/m² in the ON state. SPD film operates on 90V AC (70–110V adjustable) at 3 W/m² transparent / 0 W opaque. Both must be driven through a dedicated transformer — never wired directly to mains. The alternating current prevents polarization of the active layer and preserves film performance over the > 100,000 hour lifespan.
Yes. ElevatoX controllers support wall switches, remote controls, Wi-Fi panels, door-magnetic sensors, motion sensors, rotary dimmers, and smart-home bridges including HomeKit, Google Home, and Alexa. The 48/65V AC driver (PDLC) or 90V AC driver (SPD) pairs with these controllers without additional relays in most cases. For multi-channel installations, the wiring simulator helps plan transformer sizing and channel routing before final engineering review.
SPD film operates from -20°C to 90°C, covering most exterior applications. However, exterior-rated deployments require project-specific certification and lamination specification. Contact us for spec confirmation on unprotected outdoor use. PDLC film is rated to 70°C and is suited for interior and protected exterior installations such as covered vestibules.
Pricing is driven by technology choice (PDLC vs SPD), model tier, format (ready-to-install sheet vs semi-finished roll), film width, control add-ons, volume tiering, and shipping terms. The smart film cost page breaks down each factor; the PDLC product page covers PDLC-specific procurement in detail. FOB and EXW are both supported, and OEM/ODM options are available on bulk orders.
