HDTV Expert - Product Review: Mitsubishi HC9000 Diamond 3D Projector

The Mitsubishi HC9000D is a 3D front projector using three .61 SXRD LCoS chips and a 230-watt short-arc lamp, delivering a calibrated 2D brightness of 635 lumens with a near-perfect 2.3 gamma curve and color temperature of 6542K. In 3D mode with active shutter glasses, brightness plummets by roughly 87% to 146 lux, making the projector underpowered for low-gain screens at typical home theater throw distances. Buyers should budget for a high-gain screen (6.0 gain or similar) and ideally a 3000-lumen output to achieve satisfactory 3D performance alongside a full 2D calibration.

HDTV Expert - Epson Goes Reflective

Epson has introduced a new .74-inch reflective high-temperature polysilicon (HTPS) LCD chip delivering full 1920x1080 resolution, claiming a 40% improvement in fill factor over its D7 HTPS chips thanks to pixel pitch of approximately 8.5 micrometers. Two projectors using this technology, the EH-R2000 and EH-R4000, are priced at roughly $4,600 and $7,600 respectively and are scheduled to ship in November 2010. For home theater buyers, this positions reflective LCD as a more film-like alternative to DLP, though it still carries a notable price premium over conventional 3LCD and single-chip DLP options.

HDTV Almanac - End of the Road for Another LCoS

Syntax-Brillian has shuttered its LCoS operations, ending development of the Olevia 665H, a 65-inch 1080p LCoS rear-projection HDTV that had been priced at $1,999 and previewed at CEDIA 2007. The company traced a long lineage from Colorado Microdisplay through multiple rebrands, joining Philips among notable LCoS exits, while Sony and JVC remain the primary players in the microdisplay panel segment. For consumers, the promising budget-priced large-screen LCoS option is effectively off the table unless a buyer acquires the 665H design.

HDTV Almanac - Brillian 1080p HDTV Wins

Syntax-Brillian's 65-inch 1080p rear-projection LCoS HDTV took the LCoS RPTV of the Year Award at the Annual China Digital TV Award 2006 in Beijing, signaling strong industry recognition for the technology. The company has also formed a joint venture with a Chinese government-owned partner to manufacture LCoS imagers for domestic TV producers, with volume production targeted for July 2006. For consumers, this expansion into China's growing middle-class market could accelerate LCoS availability and competitive pricing across both domestic and export channels.

1080p into HDTV Displays

Brillian's 65-inch 6580iFB LCoS rear-projection set operates at 120 fps and accepts external 1080p signals via DVI at 24, 30, and 60 fps, using up to 320-tap FIR filters for scaling and pixel-by-pixel motion adaptive deinterlacing on 480i inputs. However, the onboard A/D converter is limited to 140 MHz, falling short of the 148.5 MHz required for analog 1080p/60Hz sources, and 24/30 fps DVI inputs incur roughly 30% temporal/spatial resolution loss pending a software update. Buyers weighing first-generation 1080p sets should understand that 1080p input acceptance, deinterlacing quality, and software upgradeability vary significantly and directly affect real-world image performance.

HDTV Almanac - SpatiaLight LCoS HDTV Bounces Back?

SpatiaLight's LCoS imager shipments to LG Electronics and Thinktek Optronics pushed the company's NASDAQ stock up 20%, but the delivery pace raises questions: only 350 of a promised 1,000 units shipped in roughly half the allotted 30-day window. This shortfall is notable given LG's prior cancellation of rear-projection HDTV models that were to use SpatiaLight imagers. Whether LCoS technology can ultimately compete against LCD and DLP designs in the rear-projection market remains an open and consequential question for display buyers.

HDTV Almanac - Downs and Ups of LCoS HDTV

Syntax-Brillian is forming a joint venture with Henan Costar Group to manufacture LCoS light engines, targeting volume production of 300,000 units annually by July 2006. This move directly addresses one of LCoS technology's persistent weaknesses - unreliable production scalability - which has limited its adoption in rear-projection HDTV displays. If the partnership meets its targets, consumers could see a broader range of Syntax-Brillian rear-projection models and potentially third-party products built around the Syntax-Brillian light engine.

Why 1080p? - Part 2 - A Brillian(t) Case

Brillian's 65-inch 6580iFB LCoS rear-projection set renders all sources at 1920x1080 via 120 fps output, using up to 320-tap FIR filters for scaling rather than simple interpolation, which preserves image sharpness and enables non-linear aspect ratio handling. The set accepts native 1080p over DVI at 24, 30, and 60 fps, though 24 and 30 fps inputs incur roughly 30% temporal/spatial resolution loss pending a firmware update. Buyers considering a first-generation 1080p RPTV will find this technical breakdown of deinterlacing, upconversion pipelines, and upgrade paths directly relevant to long-term investment decisions.

LCoS TVs Projection HD Market Trends & Analysis

HDTV Almanac - LG Aims for #1 Spot

LG Electronics plans to deploy SpatiaLight's LCoS imagers in a 71-inch rear-projection HDTV, with SpatiaLight claiming the sets will sell at roughly one tenth the price of equivalent plasma panels. If that projection holds, a 60-inch LCoS RPTV could retail between $850 and $1,000, compared to current microdisplay RPTVs in that size range selling for $3,000 to $4,000. Such pricing would put serious pressure on LCD and plasma at comparable screen sizes, though the author remains skeptical without further substantiation from LG.

HDTV Almanac - HDTV: Love and Loathing on the Big Screen

Brillian's 6580iFB is a 65-inch 1080p LCoS rear-projection television using three separate 1,920x1,080 panels for red, green, and blue, earning a strong endorsement from DisplayMate Technologies as the best 1080p HDTV at its price point. However, the company's claim of a 'true six-megapixel light engine' is technically misleading, since each full-color pixel requires one dot from all three panels, making it a 2-megapixel display rather than 6. Buyers evaluating this set should be aware that pixel-count marketing can obscure actual resolution, a problem already common in the digital camera industry.

Ed's View - HDTV at CEDIA 2005

At CEDIA 2005, 1080p displays dominated the show floor, with consumer DLP 1080p technology using an electro-mechanical toggling mirror system that splits each frame into two sub-frames to build a full 1920x1080 image at a 20-25% retail premium over 720p models. Sony's SXRD technology, a refined LCoS implementation using polarized light reflected from an aluminum mirror, delivered the highest contrast and artifact-free performance of any display shown. Buyers evaluating high-end home theater installations will find meaningful differences in picture noise and resolution between these competing 1080p approaches.
