Feasibility of using PNLC / reverse PDLC film in a small outdoor high-vibration application
Hello!
I’m looking for engineering input on the feasibility of using PNLC (reverse PDLC / switchable smart film) in a non-architectural, small-scale prototype.
Application context:
Small transparent switchable panel about 15x20 cm
Mounted on a motorcycle, exposed to outdoor conditions
Continuous vibration (single-cylinder engine)
Rain, water spray, UV exposure, temperature cycling
Power source is a 12V vehicle electrical system, likely requiring DC-DC conversion.
Functional requirement:
Two states only: transparent and diffused/opaque
Simple on/off switching, no grayscale control required.
Electrical notes from suppliers:
Most films are rated for 110–220 VAC input
Internal driver typically converts to around 48V AC operating voltage
This is not directly compatible with 12V DC systems, so an external inverter/driver would be required.
Are PNLC/PDLC films reliable outside of static architectural glass applications, especially under vibration and outdoor exposure?
How sensitive are these films to being cut into small custom sizes (around 200 cm2)?
What is the typical order of magnitude power consumption for small areas (W/m2)?
Are there better alternatives for small rugged switchable panels?
am trying to understand whether this is a viable engineering approach or if it is fundamentally unsuitable outside indoor static installations.
