The Panasonic PT-D6000US takes single-chip DLP projection to a high brightness level of 6500 lumens and claims new levels of color reproduction (up to 145 percent of conventional models) with the aid of the newly engineered RGB Booster, Panasonic's proprietary Vivid Color Control technology, and a newly engineered lamp modulation drive system. Image-processing circuits in the PT-D6000US analyze the video signal frequency range for each scene by extracting data on the distribution of high-, mid-, and low-frequency components, and they bring out fine details accordingly. Maintenance is simplified by the PT-D6000US's autocleaning filter, which makes filter cleaning unnecessary for about 10,000 hours.

Norway's projectiondesign offers its first 3-chip DLP projector, the F80, with 8000 ANSI lumens of brightness and a contrast ratio of up to 10,000:1. That rating is thanks to contrast-enhancement technologies that are unique to projectiondesign and a first for 3-chip DLP projectors, according to the company. Key features in the F80 include infinitely adjustable iris and aperture settings and motorized zoom, focus, and shift with memory for use in multiple settings with programmed calibration. The projector combines fixed and motorized optical filters for each color channel. Every lens for the F80 uses low-dispersion (LD) aspherical glass elements for high-quality focusing and sharpness, as well as high optical interfield contrast, resulting in very high perceived image quality.

Late last year projectiondesign added to its line the F35, a WQXGA-resolution (2560x1600) 6500-lumen model. "We have significantly raised the bar when it comes to number of pixels," says projectiondesign's Chris Axford, "though this comes without an increase in the imager (DMD) size. We are of course working closely with TI to secure the next step in resolution, but nothing is finalized as yet." Projectiondesign says that the F35 WQXGA platform will come with a new range of projection lenses to optimize the output of the higher-resolution chipset.

Last December, the company also introduced a new blend/warp hardware product known as MIPS. Looking toward the future, projectiondesign is developing an LED light engine for its large-venue models. (At CEDIA this year, the company introduced an LED-lit single-DLP model.) LED promises purer color transmission and a significant leap in energy efficiency.

Sanyo says its PDG-DET100L, rated at 7500 lumens with an SXGA resolution (1400x1050), is the brightest DLP projector in its class. The single-chip PDG-DET100L is outfitted with two 330W VIDI UHP lamps, contributing to its increased light output efficiency. To achieve high brightness and rich color reproduction, it is equipped with Sanyo's user-changeable color wheel system. Six optional lenses are available.
