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.
Why is PDLC considered to be smart?
The smartness of PDLCs is a result of its ability to change its transparency (technically called the transmittance) when an electrical stimulus is applied to it. This is normally by way of an alternating voltage, which exerts an alternating electric field across the PDLC material.
Nevertheless, the PDLC is only as smart as the control system which stimulates the change, which can be driven by a push button switch, a light sensor, or a building automation system.
What Form Factors are PDLC glass available in?
Switchable Toughened Glass
Switchable Laminated Glass
Switchable Double-Glazing
Switchable Window Film
Can smart glass/film be used as display screens?
Yes, smart glass/film is a rear projector screen with wide viewing angles. Even from the side one can enjoy clear, beautiful images and also in bright locations with high functional projectors.
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.
