Xpand X102-XP2PK Radio Frequency Extension for YOUniversal Electronic 3D Eyewear

3D requires as much light as possible. XPAND X102 Series features the fastest shutter technology for the brightest image. XPAND X102 Series is optimized to work with DLP chips. To better manage battery life, the DLP-Link 3D Glasses Series glasses turn "OFF" automatically. Experience! We took what was best in Cinemas and made it available for single chip DLP projectors and televisions using DLP-Link 3D communication. DLP technology uses millions of microscopic, digital mirrors that reflect light to create a stunning picture for the best projectors on the market. This imaging technology is so fast, it can actually produce TWO images on the screen at the same time: One for the "left" eye and one for the "right" eye. Then 3D glasses combine the two images to create an amazing 3D effect.
