Technology Showcase: Large HD Projectors

New technologies expand market.
The single DLP chip NP4001 from NEC with a WXGA (1280×768) native resolution has two options in its color wheel: either four segments for maximum light output or six segments for the best color depth. At 4500 ANSI lumens, the NP4001 features Eco-Mode technology — which extends lamp life by up to 25 percent, and BrilliantColor technology for advanced video processing. The NP4001 also offers a DynamicBlack capability that monitors the incoming video content and dynamically adjusts the contrast ratio to optimize picture quality for each video frame. Its AutoSense system automatically syncs the NP4001 with any computer signal. NEC's single-DLP-chip NP4001 features one-touch image optimization with 64-step image magnification with location control, and its sealed optical block minimizes the effects of dust to ensure the delivery of distortion-free images.
The PT-DW10000U from Panasonic is the world's smallest widescreen HD 3-chip DLP projector with 10,000 lumens of brightness at a 5000:1 contrast ratio. To enhance its portability, the four mercury lamps in the PT-DW10000U can run on standard 120V circuits. The projector's 75ft. throw distance makes it possible to place the projector in a control room, rather than on a stand in the audience. The Dynamic Iris in the PT-DW10000U opens and closes as the input signal changes for realtime control of light striking the DLP chips with minimal effect on light uniformity.
Panasonic also offers the PT-DW5100U, a 1280×768-pixel projector putting out 5500 lumens and a 2000:1 contrast ratio. A unique control technology in the PT-DW5100U is used to maximize the color-segment areas of the color wheel, and it comes with progressive cinema scan (3/2 pulldown) for the smoothest film presentation.
Due out early this summer, the latest three-DLP chip projector from Projectiondesign is the 8000-ANSI-lumen F80, a 1080p design with RealColor calibration technology and Projectiondesign's proprietary optical design for increased brightness and contrast levels of 10,000:1. With its patented DuArch dual-illumination architecture, lamps in the F80 can be replaced while the projector is still in operation. The F80 can be delivered with a range of pre-installed, application-specific optical filters.
In addition, the F30 projector series is Projectiondesign's top-of-the-line single-chip DLP model offering 1080p (1920×1080) or SXGA+ (1400×1050 pixel) resolution options at 6500 ANSI lumens. The F30 is available in special versions for 3D stereo display and visualization. A set of two F30 projectors can be set up to show passive 3D stereo for small or large groups with the help of Infitec wavelength multiplex imaging. The F30 can switch from 2D to 3D by deactivating the filters with an easy switch control.
