How Switchable PDLC Glass Working as Projection Screen?

01 Jan 1970

Switchable PDLC Glass, a variant of laminated glass with PDLC film, alternates between transparency when electrical power is applied and a frosted opaque state when not, potentially serving as a rear projection screen. For those without pre-installed Switchable PDLC Glass, the transparent-to-opaque transformation can be achieved by simply applying a self-adhesive PDLC film to any existing glass surface.

Rear Projection Theory

PDLC smart glass, leveraging projection technology, serves as an effective medium for displaying digital images and videos. In its frosted opaque mode, it doubles as a projection screen, while turning transparent upon the application of voltage, allowing for clear visibility through the glass.
Essentially, the projector is positioned behind the PDLC glass, with the audience viewing from the front. This dual-state capability of the PDLC smart glass—serving both as an efficient projection surface when opaque and permitting visibility through the glass when transparent—renders it an ideal solution for environments like conference rooms and classrooms that demand both privacy and the ability to project visual content.

An example of multiple rear projectors

Following you will see a Switchable PDLC Glass project, in which the Glass works as a display screen, with multiple rear projectors, they can cast the image or video on the smart PDLC glass directly, then make the glass surface into a large display screen, to show any image that you want.
