QED and 3D
QED prides itself on being at the forefront of presentation technology, constantly developing innovative audiovisual solutions by putting research and development at the very heart of its business. QED has always provided passive 3D projection systems and so it was a natural progression for QED to become the first company in the world to embrace the new advancements in active 3D technology and to develop them for use in live events. QED’s unique in-house 3D projection facility enables 3D to be properly demonstrated and for content developers to test out creative ideas in a comfortable, air-conditioned and fully serviced environment. QED has already proven that the latest and best in 3D can be delivered very cost effectively on many high profile shows, so please call us now to see what QED can do for you.

Why active 3D?
Active 3D projection delivers the brightest and highest quality 3D experience in all situations - it does not require a special silver screen and there is no restriction upon how to create, deliver and view the content. Active 3D consistently appears sharper than passive 3D, with better colour clarity and 3D performance, even when the visuals are fast paced with constant movement. Active 3D is especially ideal for use in live events because it is easy to implement and does not reduce the quality of the 2D experience in the way that all other systems do. Simply add 3D content, put on the glasses and enjoy the very best that 3D has to offer.

How does it work?
Active projection uses a single high powered high resolution DLP projector and battery powered LCD shutter glasses. The DLP chip in the projector sends a flash of light in the transition between the left and right eye images, and the active glasses recognise this encoded white signal, synchronising to the image via infrared. When a left-eye image is transmitted the lens over the right eye closes, and vice versa. This process occurs more than a hundred times per second which the brain then interprets into a 3D image.

Is active 3D more expensive than passive 3D?
Both active and passive 3D systems are more expensive to deliver than conventional projection systems, as they require additional hardware and the content creation process is more difficult and time consuming. Passive glasses are much cheaper to buy than active glasses, however active 3D utilises half as many projectors and does not require a silver screen, therefore the costs to implement each system are often very similar. For large events which already require a high level of show switching, the transition to 3D is usually a lot cheaper than implementing a separate additional 3D system; with its unrestricted viewing angles, active 3D can also be delivered to more people without having to hire a larger viewing space
