LED Technology for Digital Domes

Dome theaters have consistently faced the historic challenges of 1) low contrast due to light bounce across the dome surface, 2) the need for multiple projectors to create acceptable resolution, 3) low brightness due to low reflectivity of the dome surface to minimize light bounce and scatter, and 4) the maintenance of a complex projection system and cost of lamps and other consumables. Enter the LED dome. This breakthrough, game-changing technology addresses all of the historic concerns: 1) LED offers nearly unlimited contrast, 2) the [...]
