What is the structure of PDLC glass?
PDLC smart glass is composed of :
Outermost panels of normal float glass (or sometimes acrylic) sandwiched around:
Inner panels of optically clear PET plastic (polyethylene terephthalate), sandwiched around:
ITO (Indium Tin Oxide) which is a transparent conductor, sandwiched around:
a PDLC core comprised of liquid crystal droplets, suspended in a polymer.
Are the only states of PDLC just ON and OFF?
No, the transmittance (level of transparency) of the PDLC can be varied from 0% in the OFF state up to any value you want until you reach the maximum transmittance (normally 70% or 80%). This is done by simply altering the voltage from 0 VAC up to 70VAC, which is typically the maximum recommended voltage. This can be done electrically with a variable isolating transformer, or electronically with a switched-mode smart glass dimmer.
What is the maximum size of smart glass?
The maximum size of smart glass: 2000mm*6000mm (6.5ft*19.5ft).
How does smart glass/film works?
Smart glass works via electrical signal through activation of switches, sensors etc. Liquid crystal molecules turn to allow light to pass through and glass becomes transparent. It is opaque when not activated.
What is the power consumption of smart glass/film?
Smart glass/film consumes less than 5W/sqm.
