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.
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.
How long time does smart glass/film change from opaque to transparent?
Smart glass/film change in 1/100 second from opaque to transparent and 1/10 second from transparent to opaque.
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 warranty period for smart glass/film?
Warranty period is 2 years from date of installation. The life time of the film/glass is up to 10 years depends on varies working environment.
