See-through LCD an alternative to window projection?
June 29, 2007 by Dave Haynes
The New Launches blog has a post up about a Japanese company, called Active Inc., with a new type of LCD that has transparent properties.
It uses liquid crystal optical film instead of backlights to drive the image, allowing for something akin to a stained glass effect.
Where this could get interesting is as competition to the film, like 3M’s, that can be applied to glass and then projected onto by LCD and DLP projectors. There appear to be some real limitations to this new idea, but the who projection on glass thing is limited quite a bit by the footprint of projectors and the short lifespan and cost of bulbs.
