Self-Adhesive PDLC Smart Film (Retrofit)

Upgrade any existing glass into switchable smart glass with instant privacy on demand, without replacing framing or windows.

RETROFIT UPGRADE WITHOUT REPLACING EXISTING GLASS

ADPI's Self-Adhesive PDLC Smart Film (Retrofit) is the premier non-invasive solution for upgrading existing architectural glazing. Without dismantling frame assemblies or undergoing disruptive construction, clean dry retrofit installation delivers instant privacy and solar control.

Clean Retrofit Installation

Adheres directly onto the surface of existing glass in a dry, clean process. Ideal for corporate refurbishments and operating spaces without disruption.

Instant On-Demand Privacy

Switches in under 10 milliseconds between crystal clarity and complete visual opacity via wall switch, remote control, or smart building automation.

Diffused Natural Daylight

In its opaque state, it scatters daylight evenly throughout the interior, eliminating harsh glare without plunging rooms into darkness.

Significant Cost & Time Savings

Retain 100% of your existing glass partitions and windows. Eliminate the high fabrication, logistics, and labor expenses of installing oversized new laminated panels.

Superior UV Blockage (> 99%)

Permanently filters out over 99% of harmful ultraviolet radiation, protecting interior furnishings, wood flooring, and art from solar bleaching.

HD Rear Projection Screen

In its switched-off (opaque) state, the film acts as an ultra-high-definition rear projection surface for corporate presentations or interactive storefront displays.

HOW SELF-ADHESIVE PDLC SMART FILM WORKS

Self-adhesive PDLC Smart Film is bonded directly to the surface of existing glass via clean dry lamination. Featuring an integrated architectural optical adhesive layer, it enables rapid, non-invasive retrofit installation ideal for tenant improvements and commercial renovations.

OFF (OPAQUE) ON (CLEAR)
Self-Adhesive PDLC Film in Offices - Switched Off Opaque State Self-Adhesive PDLC Film in Offices - Switched On Clear State
STATUS: OFF • OPAQUE (FULL PRIVACY)
Voltage: 0V AC Power: 0 W/m² Direct Transmission: < 1% (Diffused 58%) Response Time: < 10 ms
OFF State (Opaque)
No Power • 0V
GLASS + ITO (0V) GLASS + ITO (0V) TOTAL SCATTERING (OPAQUE)
  • Zero Electrical Field (0V): In the absence of an applied voltage, liquid crystal droplets are randomly dispersed and disoriented within the polymer matrix.
  • Total Visual Privacy: The refractive indices of the liquid crystals and the polymer matrix mismatch, refracting and scattering light rays in all directions. Direct vision is 100% blocked.
  • Diffused Ambient Daylight: While preventing see-through vision, it allows 55% to 60% of natural sunlight to transmit as soft, glare-free diffused illumination.
ON State (Transparent)
Low Voltage • 48V–70V AC
ELECTRODE (+48V) ELECTRODE (NEUTRAL) DIRECT TRANSMISSION (CLEAR)
  • Voltage Activation (48V AC): Upon energizing, the electric field induces an instant dipole moment that aligns all liquid crystal micro-droplets perpendicularly in parallel.
  • Crystal Clarity (< 10 ms): In their aligned orientation, the refractive index of the liquid crystals matches that of the host polymer, allowing light rays to pass through without refraction.
  • Cutting-Edge Optical Clarity: Ultra-low haze (from 3.8%), eliminating the milky fogging effect typical of earlier generation PDLC films.

High-Precision Ultra-Thin Structure (~0.4 mm)

ADPI Self-Adhesive PDLC Film encapsulates switchable liquid crystal technology into an ultra-thin ~0.4 mm profile, engineered for direct retrofit application onto existing glass without autoclaves, ovens, or window removal.

  • A
    Dry Optical Adhesive (Cling):

    Ultra-transparent architectural-grade adhesive layer protected by a peel-off liner, facilitating a clean, dry, bubble-free installation.

  • B
    Anti-Scratch Hard Coat Layer:

    High-hardness protective treatment on the exposed surface, highly resistant to routine cleaning and daily contact in offices and living spaces.

  • C
    Ultra-Slim Busbar Electrodes:

    Flat-profile copper perimeter busbars that conceal cleanly beneath glazing beads, channels, or architectural trim.

SELF-ADHESIVE PDLC FILM SPECIFICATIONS

Tested and certified in international laboratories according to electrical safety, optical performance, and architectural durability directives.

FREQUENTLY ASKED QUESTIONS ABOUT PDLC SMART FILM

Technical answers regarding retrofit installation, glazing compatibility, wiring, and smart film maintenance.

It can be installed onto virtually any smooth, clean glass surface, including monolithic glass, toughened safety glass, and the interior room face of double glazing (IGUs). It is the premier choice for office partitions, residential picture windows, and existing storefronts.
Installation is performed via a dry application process following thorough mechanical cleaning and degreasing of the glass. The film features its own integrated optical adhesive layer under a protective liner. Certified technicians position the film using specialized precision squeegees to ensure perfect, bubble-free adhesion.
Ultra-thin copper busbars are positioned along the perimeter edge of the film and routed discreetly beneath existing glazing beads or concealed inside slim architectural trim profiles color-matched to the framing.
Yes. ADPI power supply controllers support standard wall switches, RF wireless remote controls, occupancy sensors, and full integration with automation protocols such as KNX, DALI, Crestron, Lutron, and voice control assistants.
The exposed surface incorporates a hard-coat anti-scratch treatment. It is easily cleaned using a soft microfiber cloth with water and mild neutral soap or isopropyl alcohol. Its operating lifespan exceeds 18 million switching cycles with zero loss of optical performance.
