From the good people at Engadget:
DLP also introduced the first 3-D front projector with Norwegian manufacturer, projectiondesign, and the brand new pico-projector stand-alone product with Optoma. The 3-D portable high-resolution active stereoscopic single-chip projector is designed for the demanding visualization, simulation and entertainment environments in applications that have not been able to achieve this level of performance in the past, while the pico product uses a pioneering DLP Pico™ chipset for mobile applications.
Benefits of Lamp-free
Due to the inherent switching speed of the DLP chip and advancements in LEDs from Luminus, a leader in LED manufacturing, consumers will benefit from the increased picture quality, reliability and value found in this new projector category. The reflective nature of the mirrors on the DLP chip allow more light to reach the screen resulting in a 50% increase in color gamut range producing more than 200 trillion colors and a contrast ratio in excess of 500,000:1. The proprietary combination of LED illumination, coupled with DLP technology elevates picture quality to a new level while eliminating the traditional projection lamp.
In addition to the expanded color and contrast performance, the illumination system has an incredibly long life and offers up to 30% lower power usage and, most significantly, hundreds of dollars in savings from lamp purchases.
Due to the sealed DLP optics, DLP projectors are inherently prepared to withstand dusty environments and unlike projectors based on other technologies; do not require a filter to protect the optics. Most DLP projectors are filter-free. This important value attribute will remain true with new lamp-free DLP projectors, eliminating potential costly filter cleaning and replacements required by other technologies.
