PDLC film specifications

Typical specifications of PDLC film: voltage, power consumption, switching time, light transmission, haze, UV blocking and lifespan.

Ranges taken from manufacturer documentation; the values of a specific product may differ. [9][10][11][12]

PropertyTypical valueNote
Drive voltage36–65 V AC, 50/60 Hz (low-voltage films from ± 24 V)Via transformer/driver from mains (100–240 V)
Power consumption± 3–7 W/m² (0.3–0.7 W/ft²)Only in the on state
Switching timetens of milliseconds to < 0.1 sSlower at low temperatures
Light transmission on± 70–85 %Measured on the film
Light transmission off± 50–70 %Most light still comes through, scattered
Haze on / off± 3–10 % / > 90 %Haze = percentage of scattered light
UV blocking> 98 %Protects interiors from fading
Operating temperature± −10/−20 °C to +60/70 °CAbove the clearing point the film turns clear or grey
Film thickness± 0.3–0.4 mmSelf-adhesive, including adhesive layer
Maximum width± 1.2–1.8 m (roll width)Larger areas with seams or several panels
Lifespanmanufacturers state 5–10+ years, hundreds of thousands to millions of switching cyclesDepends on UV, heat and humidity
