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).
What is smart glass comprised?
Smart glass is a laminated glass comprising 2pcs of glass sandwiched in between by an EVA/PVB interlayer.
What are the major reasons for using PDLC smart glass?
Enhanced security (since the glass is shatter-proof thanks to the internal plastic lamination)
Privacy (thanks to the scattering of light, essentially hiding whatever is behind the smart glass)
Glare reduction (again thanks to the scattering effect)
Reduction of the carbon footprint of the building thanks to the solar control, which reduces HVAC needs, both in summer and in winter
Reduced colour fading of interior furnishings and artworks, thanks to the rejection of UV
Creative marketing, since when the PDLC smart glass is off, the scattering effect creates a screen upon which you can project images.
What is a Liquid Crystal?
A liquid crystal is a hybrid between (i) a liquid which flows like a fluid and (ii) a crystal which is normally found as a solid, exhibiting short- or long-range symmetry.
