With 3D grabbing the lion's share of attention LED technologies have quietly evolved and are an increasingly important part of the projector category landscape.

During the 2010 CEDIA trade event the high-performance video manufacturer Runco was one of the first companies to combine LED and 3D when it introduced its LED-based D-73d 3D projector.

Wavien, Inc., a Valencia, Calif.-based video manufacturer has joined the ranks of companies that are combining what are arguably the two most impactful video technologies into a single product.

This week while exhibiting at the annual Infocomm commercial audio/video trade event in Orlando, Fla., Wavien is demonstrating a prototype 3D projector that employs its proprietary LED Recycling Technology (RLT).  "Our goal is to provide a low-cost, maintenance-free 3D projection system for home and classroom uses. Wavien's RLT technology utilizes a low-cost, street-lamp type of LED, and costs are reduced even further by using large area TFT-LCD panels to simply the light engine architecture," explains Dr. Kenneth Li, President and CEO of Wavien, Inc.  "The two-polarization system permits the use of low-cost, passive polarization eyeglasses, instead of expensive LCD shutter glasses. A further innovation is to project the images onto a simple metallic spray painted screen, which is polarization preserving and has high gain."

The company describes its LED 3D projector technology as a solution that combines left and right polarized images from two TFT-LCD panels that work in tandem with a reflective polarizer to project the combined images onto a polarization-preserving screen run through a single lens.

Wavien says it is currently working with Taiwanese manufacturers to handle the production of the projector. Infocomm attendees can visit Wavien at the show in booth #5283. The Infocomm show ends on June 17.
